The effects of salinity, nitrate (N) and phosphate (P) concentrations on the germination of Enhalus
acoroides seeds and growth were studied under laboratory condition. The highest percentage of seed
germination was at 20 ppt salinity for all concentrations of Nand P. However, there was not different (P >0.05) in
the percentage of germinated seed compared with other salinity levels of 25 and 30 ppt at all N and P concentrations. In
regard to the growth rate of seedling was found to be effective to the extension of root and lengths. In present
study, root and leaf lengths of E. acoroides seedling were observed to be significantly declined when the level of
salinity and N and P concentrations increased. Hence, alteration in the major nutrient concentration indicates
the vulnerability of E. acoroides seagrass under culturing laboratory condition, which must be avoidably
approached prior to transplantation into the meadow area for conservative management of seagrass resource.

This document summarizes a modeling approach to examine how plants may alter nutrient competition by modifying nutrient availability in the rhizosphere through the release of chemicals from roots. The model builds on a previous model of nutrient competition between plant species by incorporating mechanistic descriptions of nutrient diffusion, plant exudation of chemicals, and plant nutrient uptake. Simulations using the model suggest that the mechanisms controlling competition for bioavailable nutrients depend on soil properties, nutrient properties, and the mobility of nutrients and exudated chemicals in the soil. When diffusion is limited, exudation benefits only the exuding species, but when diffusion is widespread, exudation can benefit all species.

Landscape Resilience in a Changing Climate: From Concepts to Action

This presentation was given during a workshop at the Bay Area Open Space Council's March Gathering on Thursday, March 15, 2018 at the David Brower Center in Berkeley, CA.
Ecosystem
The movement of energy and matter in an ecosystem starts with photosynthetic organisms like plants getting energy from the sun. Plants process this energy along with water and carbon dioxide to produce glucose. Organisms that feed on producers are consumers or heterotrophs, while decomposers break down dead organic material and return nutrients to the soil or water in a cycle. Ecosystems have multiple trophic levels with producers on the first level, herbivores on the second, and carnivores and omnivores on third and fourth levels. Scavengers feed on dead organisms while decomposers break them down further.

In order to study the effects of herbivory on plant communities, we determined whether the types and concentrations of chemicals present in different aspen (Populus tremuloides Michx.) stands and understories, i.e., the foodscape, are associated with aspen use by elk (Cervus elaphus L.) and with aspen regeneration and recruitment. Transects were established in aspen stands with high, medium, and low regeneration levels (N=5 locations/regeneration level; ranging from 2,331 m to 2,724 m in elevation) in Wolf Creek Ranch in northern Utah. Using non-metric multidimensional scaling (NMDS) ordination and regression analyses, we examined the relationships between aspen regeneration, recruitment, elk presence, browsing, and other landscape elements with the foodscape (e.g., biomass and chemical composition of the understory and chemical defenses of juvenile aspen trees). The foodscape was affected by elevation and canopy height but it did not explain aspen use or indicators of aspen resilience. Our findings suggest that foodscapes of lower nutrient content–occurring at lower elevations under drier climatic conditions–are more likely to foster aspen stands with less forb and grass understory, and thus lower nutritional biomass. Nevertheless, the extent of the decline in the availability of nutrients in the understory did not appear to influence aspen browsing or indicators of aspen resilience. Future research should focus on exploring the influence of additional–and more contrasting–gradients of chemical availability in the landscape on aspen use by herbivores.

Impact of photosynthesis on crop yield
This document discusses the impact of photosynthesis on crop yield. It summarizes that photosynthesis captures energy from sunlight and converts it to biochemical energy for plant growth. While modern cultivars yield more than in the past, their total biomass is similar. There is limited scope to further improve carbon allocation, so the focus should be on increasing photosynthetic rates and growth to boost yield. The theoretical maximum radiation use efficiency for photosynthesis in crops is 11% but current crops only achieve around 3-4%, indicating potential for improvement.

This document summarizes a study on the effects of biochar amendment on soil microbial communities, greenhouse gas fluxes, and crop yields. Random matrix theory-based network analysis revealed that biochar treatment resulted in a more complex and resilient microbial community network compared to the no biochar treatment. Crop yields tended to increase for the Napier biograss but not for corn. Greenhouse gas flux data and further microbial analyses are still underway. The long term goals are to improve agricultural sustainability through biochar amendment and understand the underlying microbial processes influencing greenhouse gas emissions and carbon sequestration.Ess grade 11 summative october 2012-answer

This document summarizes a study that developed habitat suitability models for four cephalopod species (Todaropsis eblanae, Illex coindetii, Eledone moschata, and Eledone cirrhosa) in the Strait of Sicily using data on species densities and environmental variables collected from 1998-2011. Generalized additive models were used to relate species presence/absence and abundance to depth, slope, rugosity, salinity, temperature, chlorophyll-a, and light levels. The models showed different habitat preferences between species that relate to environmental conditions. Predictive maps highlighted key habitat areas that can inform conservation efforts in the region. Further analysis of long-term trends is planned.
Identifying systems and managing multiple entry points
This document summarizes the potential effects of climate change on Canada's food production system. It describes how each component of the food system may be impacted, including:
1) Crop productivity which depends on weather and could see changes in viable locations.
2) Animal production which could be affected by changes in crop production, water availability, and heating/cooling needs.
3) Fisheries may see changes in stocks and ecosystems due to shifts in water temperatures, chemistry, and ocean currents.
4) Pests, diseases and invasive species could become more prevalent with climate change. International trade and access to food in northern communities may also be impacted.
A possible approach to control soil erosion: natural farming
Natural farming is an agricultural method that aims to maintain soil fertility without tillage or compaction. It involves planting at least three different plant families together without tilling the soil to prevent degradation and erosion. A study compared natural farming to organic farming over four years on a farm in central Italy. The results showed that soils using natural farming had 50% higher levels of soil organic matter and a 20% higher structural stability index compared to organic farming. Natural farming also showed better resistance to soil deformation in compression tests. The study demonstrates the effectiveness of natural farming in increasing organic matter and protecting soils from erosion compared to organic methods.

1. The study evaluated the effects of treated wastewater irrigation on the growth, gas exchange, and mineral accumulation of Populus nigra L.
2. Irrigation with treated wastewater increased photosynthesis, stomatal conductance, and transpiration rates in poplar seedlings over the first 60 days compared to controls, but these effects decreased after 90 days.
3. Treated wastewater irrigation also increased biomass and root growth initially, but decreased the relative growth rate of poplars after 90 days compared to controls, possibly due to accumulation of trace metals like cadmium, lead, and nickel in plant tissues over time.

This document describes a sabbatical grant to study controls on plant-soil stoichiometry in dryland agroecosystems. The objectives are to 1) quantify how human management impacts plant and soil carbon, nitrogen, and phosphorus in cork oak savannas and 2) assess effects of woody plant encroachment and UV radiation on litter decomposition. Samples have been collected from sites in Portugal with different land uses and a two-year litter decomposition experiment was conducted measuring effects of litter type, location, and UV exposure.Vulnerability and adaptation to climate change
This document summarizes a workshop on climate change held in Andhra Pradesh, India. It discusses concepts like vulnerability to climate change, adaptation, types of adaptation, understanding stakeholder linkages, capacity building activities, research facilitation, sources of biomass for biochar production including Prosopis Juliflora trees, efficient biochar production methods, uses of biochar including soil application, composting, and mulching, results of biochar application like increased crop yields, and an integrated biochar and stove project called the Good Stoves and Biochar Communities Project.
Improved N Retention Through Plant-Microbe Interactions
- This poster examines the impact of crop diversification (4-year rotation) versus conventional (2-year) cropping systems on soil and rhizosphere microbial communities of maize.
- Diversified systems had richer, more even microbial communities that differed in structure from conventional systems. Diversification decreased AOA and AOB populations.
- Maize roots hosted distinct microbial communities that varied by cropping system. Diversification led to lower AOA and AOB abundances in the rhizosphere.
- Overall, diversification modified the microbial community in ways that could improve nitrogen retention through tighter coupling of carbon and nitrogen cycles.

The document discusses the benefits of both face-to-face and virtual communications for companies. It notes that while virtual communication has increased the speed of information sharing, face-to-face interactions remain important for building strong business relationships and converting prospects to customers. Specifically, the document cites a report finding that 40% of prospects became new customers and 28% of current business would be lost without face-to-face meetings. Therefore, it recommends including both face-to-face and virtual tactics in a company's communications strategy.

TreeNet–Linking net ecosystem productivity of forests to wood growth and tree...Integrated Carbon Observation System (ICOS)
TreeNet is a monitoring and research network that continuously measures and stores stem radius changes in trees at 30 sites across Switzerland. Dendrometer measurements are linked to net ecosystem productivity measured by eddy covariance. Annual stem radius increments are highly correlated with annual net ecosystem productivity. Estimates of net ecosystem productivity can be derived from dendrometer data using site-specific relationships between the two. Both growth processes and tree water relations contribute to stem radius changes and explain its close linkage to net ecosystem productivity, allowing upscaling of carbon flux measurements across landscapes.More Related Content

The document discusses the benefits of both face-to-face and virtual communications for companies. It notes that while virtual communication has increased the speed of information sharing, face-to-face interactions remain important for building strong business relationships and converting prospects to customers. Specifically, the document cites a report finding that 40% of prospects became new customers and 28% of current business would be lost without face-to-face meetings. Therefore, it recommends including both face-to-face and virtual tactics in a company's communications strategy.

TreeNet–Linking net ecosystem productivity of forests to wood growth and tree...Integrated Carbon Observation System (ICOS)
TreeNet is a monitoring and research network that continuously measures and stores stem radius changes in trees at 30 sites across Switzerland. Dendrometer measurements are linked to net ecosystem productivity measured by eddy covariance. Annual stem radius increments are highly correlated with annual net ecosystem productivity. Estimates of net ecosystem productivity can be derived from dendrometer data using site-specific relationships between the two. Both growth processes and tree water relations contribute to stem radius changes and explain its close linkage to net ecosystem productivity, allowing upscaling of carbon flux measurements across landscapes.Tudor & gold pics

1) The study examined the effects of nutrient addition on water use efficiency (WUE) and the relationship between surface temperature (Ts) and albedo using flux tower measurements at an experimental grassland site in Spain.
2) Fertilization with nitrogen and phosphorus increased plant nutrient concentrations and increased carbon uptake and latent heat flux compared to the unfertilized control.
3) Nutrient addition, particularly nitrogen, changed WUE and increased biomass growth in spring and autumn, altering the greenness of the landscape and its impact on surface temperature through changes in albedo and latent heat flux.COMPLETE DISSERTATION - PIETER ERNST COETZEE
This document summarizes a study on the response of maize to phosphorus and nitrogen fertilizers on a soil with low phosphorus status. Treatments included two nitrogen sources (urea and LAN), three phosphorus sources (MAP, NP, and APP), and five phosphorus application rates (0, 10, 20, 30, and 40 kg P/ha). The study found that both aerial and subsoil maize growth parameters responded positively to nitrogen source, with LAN yielding greater growth than urea. Aerial and subsoil parameters also responded to phosphorus source and application rate, though responses were more prominent during the first planting. Orthophosphate sources MAP and NP produced greater aerial growth than the poly

Five bacterial strains capable of degrading polycyclic aromatic hydrocarbons (PAHs) like phenanthrene, anthracene, and pyrene were isolated from an activated sludge wastewater treatment plant. The isolates were identified as Sphingopyxis ummariensis through 16S rRNA gene sequencing. Batch experiments showed the isolates could utilize the PAHs as their sole carbon and energy source. A first-order kinetic model fit the phenanthrene degradation profiles well. Rate constants for phenanthrene degradation ranged from 0.653 to 0.878 day-1, with half-lives of 0.79 to 1.06 days. The isolates showed preference for degrading phenanthrene over anthracene
Heraud Et Al. Scenedesmus Paper
This study investigated macromolecular variability in populations of the alga Scenedesmus quadricauda grown under phosphorus-replete or phosphorus-starved conditions using Fourier transform infrared spectroscopy. Infrared spectra were obtained from individual algal coenobia, which were large enough at 35 μm in diameter for high quality spectra. The P-starved coenobia on average had higher carbohydrate and lower protein content compared to P-replete coenobia. There was variability between individual coenobia, with distributions of absorbance ratios between protein and carbohydrate bands being non-overlapping between the nutrient conditions. Multivariate models using spectral data could accurately predict the nutrient status of independent coenobia based on their infrared

The document summarizes a study that evaluated the effect of omitting macronutrients, boron, copper, and zinc on the growth, chlorophyll content, and photosynthetic capacity of Eucalyptus clones. Seedlings were grown with either full nutrients or omitting individual nutrients. Omitting magnesium and zinc most limited height growth, decreasing it by 19-24% compared to omitting phosphorus. Omitting nitrogen caused the largest reduction in total chlorophyll content, as nitrogen is part of the chlorophyll molecule. Omitting sulfur significantly affected the photosynthetic efficiency of photosystem II in the plants. In general, omitting nutrients caused damage to the plants' photosynthetic apparatus.

1) The study compared the drought response and fungicide effects of two riparian tree species, Salix nigra and Platanus occidentalis, to determine their potential for ecological restoration.
2) Results showed Platanus occidentalis grew faster than Salix nigra under drought conditions. Platanus also showed higher photosynthetic rates when drought stressed without fungicide treatment, indicating the native fungi benefited its growth.
3) The findings suggest Platanus occidentalis could be a suitable alternative to Salix nigra for riparian restoration, particularly under drought conditions if native fungi are left undisturbed.

Ion imbalance in recycled nutrient solutions is caused by selective ion uptake of plants, which occurs at different
rates in different growth stages. The objectives of this study were to investigate the ion balances in both recycled nutrient
solutions and rockwool media using different renewal patterns for the nutrient solutions, and to analyze the subsequent effects
on uptake of water and nutrients. Over 12 weeks of paprika cultivation, two different renewal patterns (week units) of 6-4-2
and 8-2-2 weeks were compared with a constant renewal pattern of 4-4-4 weeks (control). The nutrient solution in the reservoir
tank was constantly maintained at EC 2.5 dS･m
-1
and pH 5.5-6.5. The changes in the ion balance with the 4-4-4 week pattern
were smaller than those with the other treatments. In the early growth stage, however, the ion balances similarly changed
among all treatments. Greater changes were subsequently observed for the 6-4-2 week pattern. Although fruit yield and shoot
fresh weight of paprika were the lowest with 6-4-2 renewal pattern, no significant differences were observed. Our results indicate
that renewal intervals can be extended in consideration of growth stage for more efficient and practical operations in closed
soilless cultures.

Effect of nitrogen and phosphorus amendment on the yield of a Chlorella sp. s...Agriculture Journal IJOEAR
Abstract— A strain of microalgae was isolated from phytoplankton samples collected from the sea coast of Amsheet, North Lebanon. Molecular diagnosis based on ribosomal RNA genes showed it to be most closely related to Chlorella sp. (GenBank accession KC188335.1) with over 90 % nucleotide identity. It was then evaluated whether N and P amendments of seawater fertilized with Guillard’s f/2 medium would improve algal growth and production. Addition of nitrogen (30 ppm) and/or phosphorus (2 ppm) to microalgae grown under laboratory conditions in 3L bioreactors resulted in improved biomass yield (mg dry matter/ L) by approximately 48%, and increased protein yield by approximately 56%, from 19.5% to 30.6% of DM content. Total protein yield/L of culture medium was therefore increased by approximately 83%. Total lipid content and carotenoid levels of the microalgal culture were not affected by the N+P amendement, whereas chlorophyll content was almost doubled. When lower levels of N+P supplementations, 10 and 20 ppm N, were tried, the biomass yield was also improved. The experiment was repeated in 20 L bioreactors in a plastic greenhouse, under normal environmental conditions, with an average temperature of 28°C and a maximum temperature of 36°C. At these relatively high temperatures, the growth rate was slowed down, but N supplementations at 10 and 20 ppm resulted in improved dry matter yield by 25 and 45% respectively, and protein content by 17 and 35%, respectively. Knowledge of the optimal culturing conditions of this local Chlorella strain is essential for its efficient production and is expected to serve future environmental and biotechnological purposes.Bbp 201

Exploration of the Ecological Niche of Chacoan Species in Environmental SpaceAlejandro Manuel Ferreiro
This document explores the ecological niches of four species predominantly found in the Chaco region - Bulnesia sarmientoi, Calomys callosus, Leptodactylus bufonius, and Tolypeutes matacus - by modeling their niches in environmental space. It finds that L. bufonius and T. matacus have broader niches while B. sarmientoi and C. callosus have narrower niches. Additionally, all species' niches show some overlap, with an area of environmental space where all four species' niches overlap. Modeling species' niches in environmental space provides new insights into the biogeography of species in the ChacoAgricultural depletion of soil nutrient in arable land
This academic article summarizes a study on the depletion of soil nutrients in agricultural land over time. The study analyzed soil samples from different arable areas in Bhopal, India twice over a one year period. The initial samples had higher concentrations of most nutrients measured compared to the later samples, indicating depletion occurred. Factors like soil pH, erosion, temperature fluctuations, and lack of organic carbon management can limit nutrient uptake by plants and availability over time. Integrated plant nutrient management that uses fertilizers, manures, and agronomic practices is recommended to sustain agricultural productivity and food supply.

This field research was presented at the 2015 3rd Global Conference on Climate-Smart Agriculture in Montpelier, France on March 18, 2015.
Climate change and climate variability pose significant risks to smallholders in the rainfed lowlands of Lao PDR. Increased surface temperatures, declining rainfall, persistent drought and depletion of soil nutrients all serve to impact agricultural productivity and livelihoods. This study investigates the impact of five treatments on soil nutrients, moisture, plant growth, and yield of water spinach (Ipomoea aquatica). The treatments tested were rice husk biochar only, biochar inoculated with manure, manure tea, inorganic fertilizer and the control. The costs and benefits of the treatments were also assessed. The randomized complete block design was used to assign five treatments and eight replications to the experimental units. Biochar was produced through slow pyrolysis. Soil physical properties were assessed with the visual soil assessment method and 15-randomized soil samples were collected for chemical analyses. Sprinklers were used for irrigation and a weather station installed to monitor the climate. Descriptive statistics and analysis of variance were used to analyze the data. Costs-benefits evaluation of the treatments was conducted to determine the net benefits relative to the initial costs ratio. The analysis of variance of mean yield indicates that the difference in yield among the treatments was highly significant. The computed F value (8.28) was higher than the F critical (2.64) at the 5% level of significance. The calculated coefficient of variance of mean yield was 17.33%. The net benefits to initial costs ratio of treatments suggest that the control (4.11), biochar inoculated with manure plus NPK (1.64), and biochar plus manure tea (1.01) are preferred. The net benefits and initial costs evaluation of treatments is important to assess whether utilizing these treatments would impact smallholders’ livelihoods. The results of this study contribute to the evidence that biochar could play an essential role to mitigate climate change risks by enhancing soil quality and increase agricultural productivity.

Polymeric composite membranes for temperature and pH-responsive delivery of d...Nanomedicine Journal (NMJ)
Abstract
Objective(s):
Nowadays hydrogels are one of the upcoming classes of polymer-based controlled-release drug delivery systems. Temperature and pH-responsive delivery systems have drawn much attention because some diseases reveal themselves by a change in temperature and/or pH. The objective of this work is to prepare and characterize composite membrane using responsive nanoparticles into a polymer matrix.
Materials and Methods:
These nanoparticles were made of the copolymer poly (N-isopropylacrylamide-co-methaçrylic acid) by an aqueous dispersion polymerization process and are responsible for dual sensitivity to temperature and pH. Morphology study with SEM, swelling behavior with Dynamic Light Scattering Technique, in vitro drug release behavior with side-by-side Diffusion Cells were also investigated in this paper. Doxorubicin hydrochloride was used as a model solute.
Results:
The study on the release of doxorubicin hydrochloride showed that the release rate was higher at pH 5 than pH 7.4, increased with the increase of temperature. Nevertheless, ionic strength only poses a minor direct effect at higher pH.
Conclusion:
Such system may be potentially used as a tumor-targeting doxorubicin hydrochloride delivery in the body.
Numerical simulation of bioremediation of poly aromatic hydrocarbon polluted
The document describes a numerical simulation of bioremediation of polyaromatic hydrocarbon (PAH) polluted soil using different species of mushrooms. Three mushroom substrates (saprophytic, symbiotic, and parasitic) were applied to six polluted soil cells for 10 weeks. Residual PAH concentrations were measured every two weeks. A kinetic model was developed using MATLAB to study biodegradation rates. Results showed the parasitic mushroom degraded PAHs fastest with a rate constant of 0.3751 day-1 and lowest residual concentration of 2.825 after 10 weeks, indicating it is most effective for bioremediating PAH pollution.

This doctoral thesis examines the relationship between fire (pyrodiversity) and biodiversity in Mediterranean-type ecosystems. It uses a comparative study of two Mediterranean regions, southeastern France and southwestern Australia, analyzing fire patterns over 50 years at multiple scales. The thesis aims to quantify the effects of fire on plant diversity, including effects on habitat, taxonomic species, and functional trait diversity. A key finding is that higher pyrodiversity, meaning greater spatiotemporal variability in fire patterns, is associated with greater diversity of successional habitats and plant life at both local and landscape scales. However, the two regions differ in their floras and responses to fire due to differing fire management and environmental conditions. Overall, the research

Abstract
Questions
Does the plant species composition of Thandiani sub Forests Division (TsFD) correlate with edaphic, topographic and climatic variables? Is it possible to identify different plant communities in relation to environmental gradients with special emphasis on indicator species? Can this approach to vegetation classification support conservation planning?
Location
Thandiani sub Forests Division, Western Himalayas.
Methods
Quantitative and qualitative characteristics of species along with environmental variables were measured using a randomly stratified design to identify the major plant communities and indicator species of the Thandiani sub Forests Division. Species composition was recorded in 10 × 2.5 × 2 and 0.5 × 0.5 m square plots for trees, shrubs and herbs, respectively. GPS, edaphic and topographic data were also recorded for each sample plot. A total of 1500 quadrats were established in 50 sampling stations along eight altitudinal transects encompassing eastern, western, northern and southern aspects (slopes). The altitudinal range of the study area was 1290 m to 2626 m above sea level using. The relationships between species composition and environmental variables were analyzed using Two Way Cluster Analysis (TWCA) and Indicator Species Analysis (ISA) via PCORD version 5.
Results
A total of 252 plant species belonging to 97 families were identified. TWCA and ISA recognized five plant communities. ISA additionally revealed that mountain slope aspect, soil pH and soil electrical conductivity were the strongest environmental factors (p ≤ 0.05) determining plant community composition and indicator species in each habitat. The results also show the strength of the environment-species relationship using Monte Carlo procedures.
Conclusions
An analysis of vegetation along an environmental gradient in the Thandiani sub Forests Division using the Braun-Blanquet approach confirmed by robust tools of multivariate statistics identified indicators of each sort of microclimatic zones/vegetation communities which could further be used in conservation planning and management not only in the area studied but in the adjacent regions exhibit similar sort of environmental conditions.
.literdecompositionprocessincofeagroforestysystem
This document summarizes the litter decomposition process in coffee agroforestry systems. It discusses how decomposition is influenced by both biotic and abiotic factors and involves complex chemical, physical, and biological processes. Decomposition acts as a natural fertilizer and plays an important role in nutrient cycling and maintaining productivity in agroforestry systems. The document reviews several studies on weight loss, decomposition rates, initial chemical composition, and nutrient release during decomposition. It concludes that more research is needed on decomposition and associated microflora and fauna in coffee agroforestry systems to better understand nutrient dynamics and develop models to describe short, medium, and long-term changes in soil nutrients.

Jocher, Georg: Addressing forest canopy decoupling on a global scaleIntegrated Carbon Observation System (ICOS)
This document discusses addressing forest canopy decoupling on a global scale. It provides background on decoupling, which occurs when there is insufficient mixing of air masses above and below the forest canopy. This can bias carbon flux measurements made above the canopy. The document outlines a global decoupling synthesis study involving over 30 forest sites. Preliminary results show decoupling occurs at all sites and is influenced by atmospheric conditions, canopy properties, and surrounding topography. Topography in particular can impact flow patterns and cause horizontal advection during decoupled periods. In conclusion, complementary below-canopy measurements are recommended to better understand decoupling and its effects on carbon flux estimates.Dukat, Paulina: How does drought impact water and carbon exchange in the temp...

This study examined how drought impacts water and carbon exchange in Scots pine forests across boreal and temperate climate zones. The researchers used the Standardized Precipitation Evapotranspiration Index (SPEI) to determine drought conditions at six Scots pine forest sites representing a range of climates. They found that prolonged drought, even over multiple summers, reduced the carbon uptake and increased the water use efficiency of the pine forests. Specifically, they observed a reduction in the assimilation rate and annual carbon sequestration at one temperate forest site after an extreme drought in 2015. Linking long-term SPEI data to on-site flux and soil measurements helped explain the forest ecosystem responses to drought across different climaticvan Zwieten, Ruthger: Performance assessment of the mobile g4301 Cavity Ring-...

This document describes methods to improve machine learning reconstructions of ocean carbon dioxide (pCO2) by incorporating physical knowledge. It presents two methods: (1) reconstructing the pCO2 residual by removing the temperature component, focusing the model on other drivers; and (2) using ocean biogeochemical models as a prior and training a machine learning model to estimate the climatological misfit between models and observations, allowing extension of reconstructions back to 1959. Both methods showed improved performance over original models in independent evaluation data, with the climatological correction approach capturing most of the improvement. The techniques demonstrate how physical knowledge can enhance machine learning reconstructions of pCO2.Kowalska, Natalia: Does Below-Above Canopy Air Mass Decoupling Impact Tempera...

The study measured CO2 fluxes above and below the forest canopy from 2015-2020 at a site in Lanžhot, Czech Republic. While decoupling between the layers occurred regularly, the analysis found no significant effect of decoupling on the annual net ecosystem carbon exchange derived from above-canopy measurements. The flat terrain around the study site likely inhibited the removal of carbon-rich air, minimizing any bias from decoupling over longer time scales.Cinelli, Giorgia: Use of outdoor radon activity concentration and radon flux ...

2) The rates of change estimated by the regression model were similar to rates estimated from observed regional trends over the study period, suggesting only small impacts from natural variability.
3) A strong linear relationship wasHavu, Minttu: Spatial variability of local carbon emissions and sinks in Hels...

This document summarizes a study estimating the spatial variability of carbon cycle components in Helsinki, Finland using the SUEWS modelling tool. The study found that CO2 emissions from human metabolism accounted for 45% of local anthropogenic emissions, while net biogenic CO2 exchange accounted for 25% of anthropogenic emissions. Spatial maps showed traffic emissions were concentrated along ring roads, building heating emissions in residential areas, and human metabolism emissions in city centers. Vegetation uptake and emissions from human metabolism were comparable to or exceeded emissions from traffic and building heating in some areas of Helsinki.Veerkamp, Hannes: Measurements of the CO2 gas transfer velocity in Jade Bay
Veerkamp, Hannes: Measurements of the CO2 gas transfer velocity in Jade BayIntegrated Carbon Observation System (ICOS)
This study measured CO2 fluxes and water turbulence in Jade Bay, Germany during winter to better understand how these parameters influence air-sea CO2 exchange. Researchers used a floating chamber method and infrared gas analyzer to measure the gas transfer velocity (k) and acoustic instruments to measure turbulent kinetic energy (TKE). Preliminary results found only a weak correlation between wind speed and TKE, and no significant correlation between wind speed and k. Further analysis will test for correlations between k and TKE and compare different instruments' TKE measurements, to improve models of air-sea CO2 flux.Suto, Hiroshi: The Greenhouse gas Observations of Biospheric and Local Emissi...

This document discusses the Greenhouse gas Observations of Biospheric and Local Emissions from the Upper sky (GOBLEU) project. The project aims to monitor Japan's climate mitigation progress using high-resolution greenhouse gas measurements from instruments installed on commercial airliners. Initial results show GOBLEU can observe nitric oxide concentrations over cities at finer scales than satellites. Comparisons to ground-based data find GOBLEU measurements correlate well, particularly in the megacity of Nagoya where satellite data correlates less. Future work includes more frequent flights and observations of solar-induced chlorophyll fluorescence over forested areas to monitor carbon sinks.Moonen, Robbert: First results of CO2 and H2O isotope-Flux Measurements in th...

This document summarizes research measuring stable isotopologues of water and carbon dioxide in the Amazon rainforest to better understand land-atmosphere exchange processes. Laser spectrometry was used to measure isotopic composition and fluxes at high temporal resolution. Preliminary results showed daytime CO2 uptake enriching ambient air in carbon-13, and water vapor fluxes originating from evaporated, fractionated sources similar to root water. Further analysis will include laboratory analysis of leaf, soil, and air samples to partition fluxes, as well as isotope modeling to integrate effects and fluxes. The goal is to describe turbulent exchange processes at small scales to improve understanding of this complex system.Mikaloff-Fletcher, Sara: MethaneSAT: Towards detecting agricultural emissions...

MethaneSAT is a new satellite funded by donations that aims to measure methane emissions globally to help reduce them. Its high resolution could allow detecting diffuse agricultural emissions for the first time from space. New Zealand's researchers will help develop methods to measure agricultural methane using MethaneSAT data. They will test these methods with measurement campaigns in New Zealand, where agriculture is a major source of methane emissions. The goal is to then apply this capability to measure methane from livestock and rice farming globally.Leggett, Graham: LI-COR Trace Gas Analyzers - Applications for Measurements o...

Radon is a useful tracer gas for estimating greenhouse gas emissions and reducing uncertainties in atmospheric transport models. However, current radon measurement techniques have inconsistencies that limit their usefulness. This study proposes a standardized protocol for radon data processing to harmonize measurements across sites and over time. Applying time response corrections to radon detector outputs from two UK sites improved correlations with methane concentrations and allowed more frequent flux estimations in atmospheric transport models. The standardized protocol has potential to better utilize radon measurements for quantifying greenhouse gas emissions.Grünwald, Thomas: Windthrow turns a former old spruce forest into a net CO2 s...

A large windthrow event in 2007 turned a former old spruce forest (DE-Hzd) into a net CO2 source for 11 years until 2017. Compared to an undisturbed old spruce forest (DE-Tha), the disturbed forest was a weaker carbon sink from 2018-2021, absorbing only 21% as much carbon. In total, the windthrow caused the disturbed forest to lose an estimated 288 tons of carbon per hectare from 2010-2021. Parallel monitoring revealed both the duration and magnitude of carbon loss following the disturbance.Davis, Kenneth: Applications of eddy covariance flux measurements in quantify...

This document summarizes research using eddy covariance flux tower measurements to quantify greenhouse gas (GHG) emissions from cities. Flux towers can directly measure CO2 and other gas fluxes continuously over urban areas. When combined with trace gas measurements and footprint modeling, flux data can be decomposed to separate biological from fossil-fuel derived CO2 fluxes. Comparisons of decomposed flux data to high-resolution urban GHG emissions inventories like Hestia show good agreement, validating the inventories. Flux towers also reveal active photosynthesis in urban turf grasses, highlighting needs to represent different urban vegetation types. Accounting for variations in rural biogenic fluxes is also important for isolating urban anthropogenic emissions.More from Integrated Carbon Observation System (ICOS) (20)

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
