Benthic macroinvertebrates
This document discusses using aquatic macroinvertebrates to monitor water quality. It outlines how macroinvertebrates can indicate the health of bodies of water, explains how they are classified by their tolerance to pollution, and describes how to sample, sort, identify, and calculate a Benthic Index of Biotic Integrity score. The sampling process involves collecting macroinvertebrates from different habitats using nets and grab samplers, preserving the samples, sorting and identifying the organisms, and calculating the score to assess the water quality and detect problems.
Fish Feed for Aquaculture - Ways to Reduce its ecological footprint
This document discusses ways to reduce the ecological footprint of fish feed used in aquaculture. Currently, fish meal is a major protein source in fish feed due to its balanced nutrients. However, overfishing to meet demand for fish meal puts pressure on small pelagic fish populations. The document explores alternatives to fish meal such as terrestrial plant proteins, insects, terrestrial animal byproducts, and algae. These alternatives can help reduce the environmental impacts of aquaculture while still providing balanced nutrition to farmed fish. In conclusion, promoting omnivorous and herbivorous fish species that can eat plant-based diets, along with sustainable production of plant proteins, can help aquaculture be produced with less ecological impact.

The degradation of surface water quality in Cameroon is linked to the absence of a functional waste management strategy. For such a strategy to be efficient, a general understanding of aquatic ecosystems will be of importance, these management strategies are particularly lacking in the eastern part of the country. To better understand and appreciate the ecosystems in the town of Bertoua, five ponds where chosen for the physicochemical and zooplankton communities analysis. Sampling on these ponds was conducted from March 2016 to April 2017 on a monthly basis. Samples for physicochemical analysis were collected at 20cm below water surface at the middle of each pond and measured were done following the recommendations of Rodier and Alpha. Biological samples were collected by filtering 50 liters of water through a 64µm mesh opening sieve. Identification was done using standard methods and identification keys. One-way ANOVA analysis was conducted to assess the potential differences between the different ponds base monthly observations. Although they are all hypereutrophic, with regard to the values of the physicochemical parameters, the five ponds showed no significant difference between them but, the structure of the zooplankton community remains very diverse. 118 zooplankton species have been identified in the five ponds. The distribution of zooplankton in these hydrosystems was mainly governed by the presence of organic matter. This study sheds light on the status and biological diversity of ponds in eastern Cameroon, data on which to rely to develop management strategies.
Bae 495r Stream Ecology
Streams are ecosystems that provide the basic requirements for life including water, nutrients, energy, and an electron acceptor like oxygen. Organisms living in streams must find ways to obtain these necessities in the flowing water environment. The riffle habitat within streams provides advantages for both autotrophs and heterotrophs due to higher oxygen, light levels, and habitat structure compared to pools. Woody debris and other obstacles are important for creating microhabitats and retaining organic matter that fuels the food web.

Mercator Ocean newsletter 20
High scientific demand, sustainable management of sea
resources, assessment and monitoring of pollution sources and of
their environmental impact, urgency to understand how does the
biologic processes link to the Carbon cycle and how do they
impact climate: oceanic biologic parameters (primary production,
biomass, and pelagic populations) are in the depths of vital stakes
for our society sustainable development.
Today, Mercator-Ocean is strongly involved in producing
operational bulletins of the physical “blue” ocean. To use new
requirements, it is going to integrate the forecasting of the living
world seas’ component and become more “green”. A first quasireal
time demonstration phase will be launched in the beginning of
2006. LOBSTER biologic model will be integrated in the Mercator
operational chain. This new stage was made possible thanks to
the Bionuts research/operational collaboration. Five structures
contribute to this project: LEGOS (Toulouse), LEGI (Grenoble),
IPSL/OCEAN and IPSL/LSCE (Paris) and the GIP Mercator-
Ocean. In the News, Patrick Monfray & al. present us this project,
its stakes, as well as some recent results.
The three other Newsletter’s articles present an overview of the
Mercator associated research works on the “biology” thematic.
François Royer & al. are interested on the pelagic species’ spatial
dynamic, unavoidable stage for a better management of the sea
resources.
A toxic bloom of the cyanobacteria, Nodularia
spumigena has been reported in the Baltic Sea. On
July 24, 2003, SeaWiFS captured this view of the

In the scope of the Bionuts project, Leo Berline & al. have studied the assimilation impact (temperature, salinity, sea level)
on the biologic parameters of coupled biology/physical model. In fact, the confrontation of physical models to biology
constraints has revealed some negative effects of the assimilation scheme on the vertical processes performance. So,
improve them is a crucial stake for the biology/physical coupling.
At last, coupling between biologic and physical models is a great opportunity for Scientists to investigate how does the
dynamic impact the biology. Isabelle Dadou & al. have looked at the Rossby waves influence on the primary production.

Crabs, heavy metals and near future ocean acidification - what do we know?
This study examines the combined effects of ocean acidification and varying heavy metal concentrations on the sand bubbler crab (Dotilla fenestrata) in estuaries in South Africa. The study aims to understand how heavy metal uptake and bioaccumulation in crabs is affected by increasing ocean acidity. Crabs, water, and sediment samples were collected from three estuary sites and are being analyzed for heavy metal content and crab tissue is being tested for toxicity when exposed to ocean acidification and heavy metals. The results of this study could help monitor pollution in the estuaries using crabs as bioindicators and inform environmental policy.
Marine Debris PowerPoint
This document summarizes a study on marine debris found on beaches. The study hypothesized that land-based debris would be more abundant on beaches than sea-based debris. Through surveys of sandy beaches along saltwater and freshwater shorelines, the study found that 98% of debris was from land-based sources, primarily plastic. The document discusses the environmental and economic impacts of marine debris, such as threats to wildlife, contaminated water, and decreased tourism. It calls for global action through increased research, education, and efforts by communities and individuals to help address the growing problem of marine debris.

This document summarizes a study that analyzed levels and sources of polycyclic aromatic hydrocarbons (PAHs) in green mussels from Cilincing waters in Jakarta Bay, Indonesia. Green mussels of varying shell lengths were collected and their flesh and guts extracted and analyzed for PAH concentrations using GC-MS. The highest PAH concentration was found in guts of the largest mussels. Ratios of PAH compounds indicated a mixed petrogenic and pyrogenic source from oil, shipyard waste, and atmospheric deposition. Risk analysis found PAH levels in mussels were acceptable for human consumption but further monitoring is needed due to carcinogenic effects.

Effect of some abiotic factors on the growth of Oreochromis niloticus Linnaeu...Journal of Research in Biology
The Growth of Oreochromis niloticus (2.6g initial average size) was studied in 100m2 earthen ponds for 180 days under tropical field environment. Varying fertilizing regimes consisting of Pennisetum purpureum (PP) and Musa sapientum (MS), two locally available weedy grasses were applied in duplicates in the experimental ponds, at the rate of 0.1-0.2 kg dry matter per m2 per day. Water quality parameters were monitored bimonthly between 8:00am-9:00am . Final average fish weight varied significantly (p<0.05) as follows: 43.85g, 35.5g, 59.5g, 24.9g and 50g, 2 respectively for PP, MS, MS+PP, T0 and T1. Corresponding daily growth were 2.2g/d, 0.1g/d, 0.3g/d, 0.1g/d and 0.2g/d. Survival rate equally varied significantly as follow: 60 %, 67 %, and 98 %, 70 % and 97 % respectively. During the study period, the results indicated the water quality were permissibole limits and can be used for livestock of Oreochromis niloticus .Pelagic Environments and Ecosystems (1)
The pelagic zone is the largest habitat on Earth, encompassing 330 million cubic miles of the open ocean. Within this zone, various species of pelagic fish and plankton are found throughout in numbers and distributions that vary depending on factors like light availability, nutrients, temperature, and pressure. The photic zone near the ocean's surface experiences a daily cycle of light and dark that is a powerful environmental signal, influencing diel vertical migrations of organisms seeking their optimum light intensity. Upwelling regions bring nutrients into surface waters, supporting highly productive marine ecosystems and fisheries. Plankton are primary producers and consumers that drift with ocean currents, and include phytoplankton like diatoms, dinoflagellates
Stakeholders’ Perception of Fish Decline in the Lagos Lagoon and Effects of S...
Stakeholders’ Perception of Fish Decline in the Lagos Lagoon and Effects of S...BRNSS Publication Hub
Lagos Lagoon provides a number of important ecosystem services that include fish supply for the indigenous
fishing communities of Ilajes and Ijaws. The Lagoon is also a sink for pollutants from various point sources,
including sawmilling activities at the Okobaba hub of the lagoon. The perception of stakeholders about the
environmental risks of these anthropogenic activities is important considerations for sustainable management
of this important coastal ecosystem. Organic pollutants such as polycyclic aromatic hydrocarbons (PAHs)
are priority pollutants that are associated with anthropogenic activities including the burning of wastes. The
early life stages of fish species are useful bioindicators of pollutant effects for environmental risk assessments.
This study investigated stakeholders’ environmental risks perception of the sawmilling activities on the
Lagos Lagoon. Furthermore, physicochemical parameters and 16 priority PAHs were assessed in surface
water, porewater, and sediment from the study area on the Lagos Lagoon. Further, the embryotoxic effects
of crude and cleaned up sediment organics and porewater extracts on the African sharptooth catfish (Clarias
gariepinus) embryos were evaluated. Most (70–93%) respondents observed fish declines, burn wastes on
the bank of the lagoon and are aware of the environmental and human health risks of their activities. High
molecular weight PAHs dominated the PAHs profile, especially in the sediment. Developmental abnormalities
and decreased hatching success were observed in C. gariepinus embryos exposed to extracts from the test
site compared to the controls though non-significant (P > 0.05). The results show the environmental risks
of sawmill activities on the Lagos Lagoon. There is a need for targeted environmental management and
stakeholders’ engagement to forestall further coastal degradation and promote sustainable fisheries in the
lagoon in support of the UN sustainable development goal three (life below water).Microplastics Report
The document discusses the extent to which the oil and gas industry contributes plastics and microplastics to the marine environment. It analyzes data from the North Sea region, where extensive oil and gas operations occur. The report examines definitions of marine litter, plastics, and microplastics. It investigates microplastic uses in offshore oil and gas operations, particularly in drilling fluids, proppants, and cement. The report also assesses studies by Cefas and others on microplastic contributions from various offshore activities and pathways. It concludes that while the oil and gas industry currently contributes minimally to marine microplastics, further investigation and cooperation is needed to fully understand and address microplastic sources and impacts.
Comparision of biogeography of microbial mapping
This document outlines a research study on the biogeography of microbes in the Neil and Havelock islands. The objectives are to isolate bacteria and actinobacteria from sediment samples using molecular techniques, study their spatial and temporal variation, and understand differences between the islands through spatial mapping. So far, sediment samples have been collected from both islands and marine bacteria and actinobacteria isolated and identified using molecular methods. Mapping of microbial diversity and biogeography is underway.
microbial loop
This document provides an overview of the microbial loop in marine ecosystems. It discusses how bacteria consume dissolved organic matter released by phytoplankton and protozoans. These bacteria are then consumed by protozoans like flagellates and ciliates, recycling nutrients and carbon back into the food web. Approximately 60% of energy in marine food chains is estimated to pass through this microbial loop. The loop links dissolved organic matter to microbes and micrograzers, and is crucial to ecosystem function by transferring carbon and nutrients between trophic levels.
Microplastics in fish from the KZN Bight
This document summarizes a study on microplastics found in fish caught in the Agulhas current large marine ecosystem off the coast of KwaZulu-Natal, South Africa. The study aimed to quantify microplastic particles in fish from different regions, including an eddy in the Kwazulu-Natal Bight, and determine if there were differences between fish from epipelagic and mesopelagic zones. Microplastics were found in 34% of fish studied. The most common shapes of microplastics found were broken pieces of larger plastic items (56%) and thread-like pieces resembling fishing line (29%). Some fish contained up to 6 microplastic particles. The study acknowledges contributions from fund

Effect of some abiotic factors on the growth of Oreochromis niloticus Linnaeu...Journal of Research in Biology
The Growth of Oreochromis niloticus (2.6g initial average size) was studied in 100m2 earthen ponds for 180 days under tropical field environment. Varying fertilizing regimes consisting of Pennisetum purpureum (PP) and Musa sapientum (MS), two locally available weedy grasses were applied in duplicates in the experimental ponds, at the rate of 0.1-0.2 kg dry matter per m2 per day. Water quality parameters were monitored bimonthly between 8:00am-9:00am . Final average fish weight varied significantly (p<0.05) as follows: 43.85g, 35.5g, 59.5g, 24.9g and 50g, 2 respectively for PP, MS, MS+PP, T0 and T1. Corresponding daily growth were 2.2g/d, 0.1g/d, 0.3g/d, 0.1g/d and 0.2g/d. Survival rate equally varied significantly as follow: 60 %, 67 %, and 98 %, 70 % and 97 % respectively. During the study period, the results indicated the water quality were permissibole limits and can be used for livestock of Oreochromis niloticus .Pelagic Environments and Ecosystems (1)
The pelagic zone is the largest habitat on Earth, encompassing 330 million cubic miles of the open ocean. Within this zone, various species of pelagic fish and plankton are found throughout in numbers and distributions that vary depending on factors like light availability, nutrients, temperature, and pressure. The photic zone near the ocean's surface experiences a daily cycle of light and dark that is a powerful environmental signal, influencing diel vertical migrations of organisms seeking their optimum light intensity. Upwelling regions bring nutrients into surface waters, supporting highly productive marine ecosystems and fisheries. Plankton are primary producers and consumers that drift with ocean currents, and include phytoplankton like diatoms, dinoflagellates

Stakeholders’ Perception of Fish Decline in the Lagos Lagoon and Effects of S...BRNSS Publication Hub
Lagos Lagoon provides a number of important ecosystem services that include fish supply for the indigenous
fishing communities of Ilajes and Ijaws. The Lagoon is also a sink for pollutants from various point sources,
including sawmilling activities at the Okobaba hub of the lagoon. The perception of stakeholders about the
environmental risks of these anthropogenic activities is important considerations for sustainable management
of this important coastal ecosystem. Organic pollutants such as polycyclic aromatic hydrocarbons (PAHs)
are priority pollutants that are associated with anthropogenic activities including the burning of wastes. The
early life stages of fish species are useful bioindicators of pollutant effects for environmental risk assessments.
This study investigated stakeholders’ environmental risks perception of the sawmilling activities on the
Lagos Lagoon. Furthermore, physicochemical parameters and 16 priority PAHs were assessed in surface
water, porewater, and sediment from the study area on the Lagos Lagoon. Further, the embryotoxic effects
of crude and cleaned up sediment organics and porewater extracts on the African sharptooth catfish (Clarias
gariepinus) embryos were evaluated. Most (70–93%) respondents observed fish declines, burn wastes on
the bank of the lagoon and are aware of the environmental and human health risks of their activities. High
molecular weight PAHs dominated the PAHs profile, especially in the sediment. Developmental abnormalities
and decreased hatching success were observed in C. gariepinus embryos exposed to extracts from the test
site compared to the controls though non-significant (P > 0.05). The results show the environmental risks
of sawmill activities on the Lagos Lagoon. There is a need for targeted environmental management and
stakeholders’ engagement to forestall further coastal degradation and promote sustainable fisheries in the
lagoon in support of the UN sustainable development goal three (life below water).Microplastics Report
The document discusses the extent to which the oil and gas industry contributes plastics and microplastics to the marine environment. It analyzes data from the North Sea region, where extensive oil and gas operations occur. The report examines definitions of marine litter, plastics, and microplastics. It investigates microplastic uses in offshore oil and gas operations, particularly in drilling fluids, proppants, and cement. The report also assesses studies by Cefas and others on microplastic contributions from various offshore activities and pathways. It concludes that while the oil and gas industry currently contributes minimally to marine microplastics, further investigation and cooperation is needed to fully understand and address microplastic sources and impacts.
Comparision of biogeography of microbial mapping
This document outlines a research study on the biogeography of microbes in the Neil and Havelock islands. The objectives are to isolate bacteria and actinobacteria from sediment samples using molecular techniques, study their spatial and temporal variation, and understand differences between the islands through spatial mapping. So far, sediment samples have been collected from both islands and marine bacteria and actinobacteria isolated and identified using molecular methods. Mapping of microbial diversity and biogeography is underway.
microbial loop
This document provides an overview of the microbial loop in marine ecosystems. It discusses how bacteria consume dissolved organic matter released by phytoplankton and protozoans. These bacteria are then consumed by protozoans like flagellates and ciliates, recycling nutrients and carbon back into the food web. Approximately 60% of energy in marine food chains is estimated to pass through this microbial loop. The loop links dissolved organic matter to microbes and micrograzers, and is crucial to ecosystem function by transferring carbon and nutrients between trophic levels.
Microplastics in fish from the KZN Bight
This document summarizes a study on microplastics found in fish caught in the Agulhas current large marine ecosystem off the coast of KwaZulu-Natal, South Africa. The study aimed to quantify microplastic particles in fish from different regions, including an eddy in the Kwazulu-Natal Bight, and determine if there were differences between fish from epipelagic and mesopelagic zones. Microplastics were found in 34% of fish studied. The most common shapes of microplastics found were broken pieces of larger plastic items (56%) and thread-like pieces resembling fishing line (29%). Some fish contained up to 6 microplastic particles. The study acknowledges contributions from fund

Ecology3
This document provides an overview of ecology and different biomes. It begins with questions about ecological concepts like elements, cycles, and bacteria involved in nutrient cycles. It then defines biomes as large regions characterized by certain climates and plant and animal communities. The main biomes discussed are tropical rainforests, savannas, deserts, temperate grasslands, temperate deciduous forests, taiga, and tundra. Key factors that determine biomes are described as temperature, precipitation, latitude, and seasonal variations. Each biome's characteristic climate and representative vegetation are summarized.
Ecology good
Ecology is the scientific study of interactions between organisms and their environments, focusing on energy transfer. The environment includes biotic factors like living organisms and abiotic non-living factors like temperature and soil. Organisms exist at different levels of organization from individual to population to community to ecosystem to biosphere. Feeding relationships include producers, consumers at different trophic levels, and decomposers. Relationships can be symbiotic like mutualism, commensalism, or parasitism. Nutrients cycle through ecosystems like water, carbon, and nitrogen to maintain homeostasis. Toxins can biomagnify and increase in concentration up food chains.
Capstone_Presentation_2015.pptx
This study analyzed changes in soil chemistry following prescribed burns in a pine-hardwood forest. Soil and leaf litter samples were collected from control sites and sites one month, two months, and six months after burns. Isotopic analysis found nitrogen isotope concentrations significantly increased one month after burns before declining to normal levels by two months. Phosphorus, potassium, and magnesium levels also temporarily increased before returning to normal within two months. Overall, prescribed burns had a minimal impact on some nutrients but increased levels of important nutrients like phosphorus and potassium, promoting nutrient cycling and positively impacting vegetation.
Ecology2
This document discusses several biogeochemical cycles that occur within ecosystems, including the water, carbon, nitrogen, and phosphorus cycles. It explains that the main elements that make up living things, like hydrogen, carbon, nitrogen, and oxygen, are held primarily in the atmosphere and cycle between reservoirs in the environment and organisms. The water cycle involves evaporation from bodies of water, condensation into clouds, and precipitation back to the earth. The carbon cycle relies on photosynthesis in producers and respiration in all organisms. Nitrogen fixation by bacteria allows nitrogen to be used by living things. Phosphorus cycles between rocks and the soil and through living organisms.
Ecology review 2
The document summarizes several natural cycles:
1) The carbon cycle involves carbon sinks like plants, forests and soil that absorb carbon, and carbon sources like combustion, respiration and decomposition that release carbon.
2) Nitrogen fixation converts inert nitrogen gas into bio-usable forms through atmospheric fixation by lightning or biological fixation by microbes and plants. Nitrification converts ammonia into nitrites and nitrates which plants can use but are soluble and can leach from soil.
3) The hydrological cycle describes the continuous movement of water above, on and below the Earth's surface, with the same amount of water circulating but individual molecules coming and going quickly.
Ecology - Chapter 5 Section 2
The document discusses the carbon, nitrogen, and phosphorus cycles, explaining how each element cycles through the environment and is used by organisms. It also describes how human activities like burning fossil fuels, agriculture, and deforestation are disrupting these natural cycles and releasing excess carbon, nitrogen, and phosphorus into the environment, leading to issues like global warming, acid rain, and pollution of waterways.
Nitrogen cycle PERIOD 5
The nitrogen cycle describes the movement of nitrogen through the environment. It involves nitrogen fixation by bacteria, ammonification by decomposers, nitrification by soil bacteria, and denitrification by bacteria in waterlogged soils that converts nitrogen back to its gaseous form. Human activities such as fossil fuel combustion, use of nitrogen fertilizers, and livestock ranching have significantly increased the global nitrogen cycle, causing issues like smog, acid rain, eutrophication, and increased greenhouse gas emissions. While some seek solutions, many nations prioritize food production over environmental impacts.

The document summarizes a study on the effect of nitrogen on mycorrhizal colonization of Populus grandidentata roots. Methods included collecting roots from nitrogen treatment and control plots, quantifying ecto- and arbuscular mycorrhizal colonization under a microscope. Preliminary results found that nitrogen decreases mycorrhizal colonization, with control trees showing more activity than treatment trees. The student will continue this work for their senior thesis and try different staining techniques to further examine the impact of nitrogen on mycorrhizal associations.
Organization of communities and ecosystem
The document discusses biological organization from the subatomic to the ecosystem levels. It presents a pyramid of 12 levels of biological organization, ranging from the lowest levels of subatomic particles and atoms, to molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, and finally ecosystems at the top level. It explains that life begins at the cellular level and progresses through higher levels of organization within this pyramidal framework.

1.1 WHY MARINE CONSERVATION BIOLOGY?
So you have chosen to do Marine Conservation Biology! Congratulations on your wise choice.
There is an urgent need to focus science and research on conservation issues in the marine
environment. Many marine ecosystems are on the verge of collapse, many habitats have been
decimated and many believe we are on the threshold of a human-induced mass extinction event.
The mission of this subject is to develop scientific skills and enhance employment prospects to
confront the biodiversity crisis in the marine environment.
Conservation biology is the application of scientific methodology to the conservation of biological
diversity. It is an ecological science that targets the causes and seeks remedies to the disastrous
global decline in biodiversity that we have already seen on land and are beginning to see in our
harbours and oceans. Marine conservation biology is a relatively new and rapidly changing
discipline in marine biology. New concepts are devel.
Unep deep sea biodiversity
This report provides an overview of key socio-economic, management, and governance issues relating to conservation and sustainable use of deep-sea ecosystems and biodiversity. It highlights the current understanding and identifies knowledge gaps. The deep sea is home to diverse ecosystems and provides many goods and services. However, human activities like deep-sea fishing, oil and gas extraction, and mining are threatening habitats and increasing pressures. Effective governance is needed to balance conservation with sustainable use, but challenges include implementing an ecosystem approach, addressing uncertainties, and improving multi-level cooperation. Further research can help close knowledge gaps and better inform policymaking.
Charting Advances in Marine Science
The immense region of the world’s seas has long enraptured human interest, filling in as both a wellspring of secret and a boondocks for logical investigation. Throughout the long term, propels in sea life science have unfurled like the pages of a convincing story, uncovering the complexities of maritime environments, the elements of marine life, and the significant impact of the seas on Earth’s environment. From the beginning of sea investigation to the present state of the art advancements, the excursion of understanding our seas has been set apart by constant development and disclosure.
This gathering plans to diagram the momentous advances in sea life science, giving a thorough outline of the developing scene of maritime exploration. We will investigate the pivotal moments, revolutionary technologies, and collaborative efforts that have shaped our understanding of the oceans as we delve into the depths of this multidisciplinary field. From the revelation of aqueous vents and the planning of sea flows to the investigation of outrageous remote ocean conditions, every part in this investigation of sea life science mirrors the vigorous quest for information that drives researchers, specialists, and pioneers the same.
The job of sea life science reaches out past the domains of unadulterated interest. It assumes a critical part in tending to squeezing worldwide difficulties, for example, environmental change, overfishing, and the protection of biodiversity. As we face a period of exceptional ecological change, the bits of knowledge acquired from sea life science become progressively crucial for educated independent direction and supportable administration regarding our seas.
Anastasija Martjanova Bachelor project report 2015
This document presents a bachelor thesis that investigated the habitat behavior and sediment preferences of juvenile European eels (Anguilla anguilla). Laboratory experiments were conducted over 10 days with 127 eels ranging from 70-130mm in length. The experiments found that 72% of eels preferred larger substrates like medium and large gravel, while only 15% preferred sand with vegetation and 12% preferred small gravel. Observation of the eels also showed that burial activity occurred continuously throughout the experiments, while the highest number of eels in the water column was observed after one hour. The results provide important insights into juvenile eel habitats that can help inform coastal zone management and protection of habitats critical to eel populations.

The document discusses the complexity in predicting coral reef responses to climate stressors like temperature and ocean acidification. It presents two models examining community interactions and biochemical feedbacks between corals and the environment. Scenarios altering the stress impacts on different species showed predictions are sensitive to uncertainties. Biogeochemical coupling between corals and water further complicates predictions. The conclusion is that simple projections of reef responses to climate change are dangerous, and more studies considering multiple stressors and species are needed.

Beyond taxonomy: A traits-based approach to fish community ecology
This document discusses using traits-based approaches to understand fish community ecology. It begins by outlining threats to freshwater fishes like habitat loss and pollution. The author argues that traits-based ecology enhances understanding of ecological patterns and processes, provides opportunities for generalization, and links biodiversity and ecosystem function. Research on fish traits can explain where species live, how many coexist in an area, and how they respond to environmental change. The author presents on using traits to predict extinction risk of fishes and anticipate how communities will respond to environmental change. Body size correlates with extinction risk, with smaller-bodied fishes less vulnerable. Life histories have evolved trade-offs that enable coping with ecological challenges. Traits may indicate ecosystem implications

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
