The document discusses a study on how specific leaf area (SLA), a measure of leaf thickness, changes with canopy position and nutrient amendment treatment in trees. The study found that relative growth rate was higher in trees given a phosphorus treatment. It was hypothesized that SLA would decrease more slowly with increasing canopy position in phosphorus-treated trees. Methods involved measuring SLA of leaves sampled from different heights on 4 trees. Preliminary results found sun leaves had lower SLA and phosphorus trees maintained thinner leaves higher in the canopy. Future work planned to replicate the study and measure additional leaf traits.

Forest Gap Models- Silviculture
Gap models are used to simulate changes in forest gaps over time. They project the annual growth and death of individual trees as well as regeneration of new trees. The first gap model was JABOWA, developed in 1972. Gap models emphasize the response of individual trees to their environment and how trees modify those conditions. Growth is modeled based on factors like leaf area and size. Environmental constraints and competition between trees are also modeled based on light availability, soil resources, and other factors. Mortality and establishment of new trees are also modeled stochastically based on factors like growth rates. Gap models can be used to examine vegetation response to changing environments and predict forest composition and yield over time.
Competition for space, light and nutrient in forest stands shanta kafle
This document summarizes a presentation on competition for space, light and nutrients in forest stands. It begins with an introduction defining competition and describing it as either symmetric or asymmetric. It then outlines the presentation's sections and provides details on three methodologies studied for assessing regeneration status and seedling survival under different spacing conditions. The results section finds seedling density and growth correlated with gap size and neighbor distance. Discussion notes competition's influence on evolution. The conclusion states competition alters species survival and growth, with light competition asymmetric and below-ground competition symmetric. It recommends further study to harmonize compatible species arrangements.

Relative Growth Rate (RGR) - Plant Physiology
The document summarizes several studies on plant growth analysis and the parameters used to describe and quantify growth. It discusses how relative growth rate (RGR) can be factored into leaf area ratio (LAR), specific leaf area (SLA), leaf mass ratio (LMR), and net assimilation rate (NAR). SLA, LMR and the proportion of resources allocated to leaves versus other plant parts influence LAR and growth. NAR is influenced by photosynthesis, respiration, and carbon allocation. Studies found SLA and allocation to leaves had a stronger influence on RGR than NAR between plant species.
Light interception
This document provides an overview of a seminar on light interception by trees in relation to multistoried cropping systems. It discusses the introduction and benefits of multistoried cropping, including more efficient use of space, resources, and solar energy. Examples of multistoried cropping patterns combining trees, shrubs and herbaceous plants at different heights are provided. The document also covers principles of multistoried cropping systems, methods for measuring light interception, and the effects of light interception on crop growth and production.
Parameters of primary productivity
This document discusses parameters used to analyze plant growth, including leaf area index (LAI), leaf area ratio (LAR), leaf area duration (LAD), specific leaf area (SLA), specific leaf weight (SLW), net assimilation rate (NAR), relative growth rate (RGR), crop growth rate (CGR), harvest index (HI), and others. It provides the definitions and equations for calculating each parameter, and cites the scientists who originally proposed the terms.

This document discusses using imaging spectroscopy and field studies to distinguish between nitrogen (N) and phosphorus (P) additions from the air. It finds that N addition reduced reflectance by producing more chlorophyll and absorbing more light, while P addition increased reflectance. When a model was trained on treatment classes (control, N, P, N+P) for 75% of plots, it predicted the other 25% of plots with 83% accuracy. Field measurements of resin-available N and P in soil aligned with clustering of tree-top spectra responses to nutrients. This indicates trees can act as remote signals of belowground nutrient availability and function.

Mycorrhizal type and co-limitation of forest productivity. Noah Blumenthal
This study investigated how the two types of mycorrhizal associations in northern hardwood forests (arbuscular mycorrhizal and ectomycorrhizal) influence nutrient limitations and forest productivity. The researchers measured annual stem growth in mature forest stands between 2015-2019. They found that nutrient additions of nitrogen and phosphorus had interactive effects on productivity, suggesting co-limitation, and this effect was stronger for arbuscular mycorrhizal tree species than ectomycorrhizal species. They concluded the greater relative abundance of arbuscular mycorrhizal trees promotes nutrient co-limitation in mature northern hardwood forests.
Grow with the changes: Forest succession and woody debris. Joe Nash
1) The document analyzes data from two studies to quantify stocks of downed dead wood in northern hardwood forest stands of different ages.
2) Thirteen forest stands ages 31-145 years old were inventoried for coarse and fine woody debris using line intersect and nested subplot sampling.
3) The primary objective is to distinguish the characteristics of woody debris corresponding to different successional stages in northern hardwood forests.
Litterfall and soil respiration fluxes in the MELNHE study. Thomas Mann
This document summarizes a study examining how soil respiration and litterfall in northern hardwood forests are controlled by nutrient availability. The study measured soil CO2 fluxes and collected fine litterfall from treatment plots with different nitrogen and phosphorus additions across 13 forest stands from 2008-2019. Preliminary results found that nitrogen addition lowered soil respiration in nitrogen-poor sites from 2011-2013. While apparent trends were observed, the authors note that statistical analysis is still needed and fertilization effects on litterfall may be more complicated. Next steps include further statistical analysis and exploring why nutrient additions did not significantly impact soil respiration rates.
N-P co-limitation in young northern hardwood forest. Tim Fahey
1) The document discusses nitrogen, phosphorus, and fine roots in young northern hardwood stands.
2) It presents the hypothesis that growth of new fine roots in these stands may be co-limited by balanced mineral nutrition of nitrogen and phosphorus.
3) A factorial experiment using ingrowth cores found that fine root growth and biomass increased at the plot level in response to the addition of both nitrogen and phosphorus, but not from the addition of only one nutrient.

This document discusses an experimental study that examined the effects of nutrient amendments on mycorrhizal colonization and root morphology in red maple seedlings. The study predicted that nitrogen amendments would decrease vesicles in roots, phosphorus amendments would increase coil structures, and root morphology would vary depending on mycorrhizal colonization and structures under each treatment type. It then describes the experimental design, data collection process involving root processing and staining, and analysis of mycorrhizal colonization and root morphology.

(1) The MELNHE study examines nutrient co-limitation of forest productivity across 13 forest stands of different ages located in three sites. Fertilization experiments add nitrogen, phosphorus, or both to test for co-limitation.
(2) So far, tree growth has been found to be primarily limited by phosphorus rather than nitrogen or co-limitation.
(3) A new study tested whether root growth is directly limited by nitrogen or phosphorus availability, or responds to aboveground nutrient allocation. Fine root growth responded directly to nitrogen addition but not phosphorus addition, and roots foraged more in phosphorus-rich patches.

This document summarizes a study that examined how the physical, chemical, and metabolic characteristics of sugar maple leaves vary with their depth in the tree crown and with the addition of nutrients. The study found that foliar nitrogen and chlorophyll increased deeper in the crown and with nitrogen addition, while foliar phosphorus increased with phosphorus addition. The study concludes that most leaves are shaded rather than just "sun" or "shade" leaves, and that examining the vertical gradient in a tree crown can help reveal relationships between leaf characteristics and nutrients.
The timing of senescence affects foliar p resorption dan hong
This document discusses a study on the timing of senescence and its effects on foliar phosphorus (P) resorption. The study (1) examined how foliar concentration and resorption of P and other nutrients varied with N, P, and N+P additions and between species, and (2) investigated whether the timing of senescence affected foliar resorption with nutrient additions. Field collections of green leaves and litter were made over multiple dates in the fall. Results showed adding N increased foliar N but decreased foliar P, while adding P increased foliar P. P resorption efficiency was lower under P additions and proceeded over the course of the fall.
Space wars the fight for light in the stands of bartlett sarah congress
This document discusses using LiDAR to map and quantify forest canopy structure within stands at Bartlett, Hubbard Brook, and Jeffers Brook. The first steps are to create maps of the tree canopy and describe the position of each species. Field data on species heights is collected along transects and recorded. Next steps are to combine LiDAR and field data to create species-specific vegetation area index profiles and determine if treatments have affected species dominance or position in the canopy.
Having a stake in nutrient cycling effects of n and p addition on wood decay...
In a 3-year pilot study, researchers placed sugar maple wood stakes in forest stands to examine the effects of adding nitrogen, phosphorus, both nutrients, and a control on wood decay. Over 273 stakes were distributed across plots with different nutrient additions or a control at 3 sites. The stakes will be collected and analyzed to determine percent mass loss over the study period, with future analysis of nutrients, soil microbes, and their role in wood decay.

Collecting fungal sporocarps allows researchers to survey the effects of nutrient additions on mycorrhizal fungi fitness over a larger area than soil samples alone. The study aims to determine how ectomycorrhizal sporocarp abundance and fungal community composition vary with nitrogen, phosphorus, and combined nutrient additions and between seasons. Over 4,000 sporocarps from 35 genera and 160 morphospecies were collected and will be identified using genetic techniques to analyze impacts of nutrient manipulations.
Does the fate of n depend on p availability in soil - samuel butler
This document discusses using an N15 experiment to determine if the fate of nitrogen (N) in soil depends on the availability of phosphorus (P). Previous research found that adding phosphorus suppresses resin-available nitrogen in soils. Additional studies showed that trees grew more in response to added phosphorus in mid-aged and old growth forests, but responded more to added nitrogen in younger forests. The proposed experiment would use the N15 isotope to trace nitrogen pathways through soil organic matter, plant roots, the microbial biomass, and mineral soil.

This document summarizes a study estimating belowground carbon allocation in forests by measuring soil respiration and aboveground litter inputs over multiple years. The researchers found that nitrogen decreases soil respiration and likely belowground carbon allocation, while phosphorus decreases leaf litter production. Preliminary results suggest phosphorus may matter more for aboveground growth while nitrogen affects belowground processes to a greater degree.

The document discusses a study examining how nutrient treatments affect germination rates and seedling survival of American beech and sugar maple. The study had three hypotheses: 1) germination and survival of maple would be highest with calcium addition; 2) germination and survival of beech would reflect limitation of nitrogen or phosphorus; and 3) survival may reflect nutritional value of seedlings. Methods involved counting germinants and seedlings in nutrient treatment plots over two years. Results showed beech germination increased with nitrogen and phosphorus addition, while maple decreased. Seedling survival decreased with nitrogen and phosphorus addition but increased with calcium addition, with no difference between nitrogen and phosphorus effects.
And you thought there were no earthworms in our forests
There were few earthworms found at Bartlett but many earthworms were found at Jeffers Brook. Plots at Jeffers Brook with added nitrogen had fewer earthworms, while plots with added calcium had more earthworms.

Forest inventory crews were analyzed to determine measurement errors in tree diameter. The study found bias may exist due to penalties for observations more than one class off. While measurement error magnitude was identified, the most uncertain measurements may not be the most important to improve. Propagating the errors into forest inventory data product calculations like timber volume and carbon storage will show which measurements are most important to improve.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

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).
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
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.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
