Summary: Aquatic ecosystems are impacted by various environmental stressors, and it is crucial to understand how ecosystems respond to stressors and their combined effects on ecological status. Bayesian Networks are used to simulate stream macroinvertebrates' responses to multiple stressors, providing a promising avenue for scenario analyses in restoration management.

Summary: The study found that hydropeaking has a significant impact on the grayling population in large Alpine valleys, with flow regulation and river morphology being key factors. The use of pooled bootstrapping can further validate these effects and provide insights for conservation and restoration strategies.

Summary: Rice production worldwide saw slight growth in water and land use as well as CH4 emissions from 2000 to 2016, but significant improvements in production efficiency led to substantial savings in water resources, land, and emissions. Domestic consumption covered the majority share (94%) while international trade played a less significant role (6%), although it was relevant for some Asian and African countries. Increasing yield by 0.5 tonnes/ha resulted in a global reduction of about 10% for each environmental stressor, suggesting potential trade-offs among them.

Summary: This study investigated the migratory behavior of an endemic fish, Prochilodus hartii, in a scenario of habitat fragmentation, flow alteration, hybridization with alien fish, and controversial management practices caused by the Irape Hydropower Dam. The results show how multiple stressors create a complex scenario where the conservation of migratory fishes is made more difficult.

Summary: Fluvial systems are highly sensitive to changes in terrestrial ecosystems and the impact of multiple stressors, requiring a social-ecological framework to analyze and address these dynamics. By identifying key drivers in Pampean streams and providing leverage points to avoid social-ecological traps, this approach can be applied to improve sustainability of fluvial social-ecological systems worldwide.

Summary: Many streams and rivers in the Afrotropics are facing multiple stressors, and there is a need for cost-effective tools to assess and monitor ecological changes. This study compares the performance of different indices in assessing ecological condition of Afrotropical rivers, and finds that the macroinvertebrate-based index of biotic integrity (M-IBI) performs better than other indices. It suggests the importance of testing and evaluating indices before their use in biomonitoring streams and rivers.

Summary: The UK faces multifaceted challenges in water resource management due to acute and chronic stressors, with the COVID-19 pandemic exacerbating the situation by increasing water demand unpredictably. It is suggested that a more integrated approach beyond traditional methods is needed to enhance resilience in water demand management.

Summary: Aquatic ecosystems contribute 50% of global productivity and play a crucial role in mitigating climate change. Factors such as water temperature, ocean acidification, nutrient availability, deoxygenation, and exposure to UV radiation interact to either enhance or decrease productivity. While ocean warming and deoxygenation may have opposite effects on mitochondrial respiration, they synergistically affect plankton migration and N-2-fixation of diazotrophs. Ocean acidification and elevated pCO(2) have controversial effects on marine primary producers, but they can worsen viral attacks on microalgae and reduce calcification of algal calcifiers when combined with UV radiation. Field observations over a long period of time are limited, but future studies are expected to explore the responses and mechanisms to multiple drivers in different regions.

Summary: This introductory chapter of our Environment International VSI outlines the recommendations for future research, emphasizing the role of waterbirds as food web sentinels, the dynamics of hazardous substances in the Baltic Sea food web, and the potential impacts of climate change. It also highlights the need to further develop new frameworks within the BALTHEALTH project for energy and contaminant transfer at the population level and their long-term effects on top predators in the Baltic Sea.

Summary: This study found that the response of epifauna in marine systems to warming is influenced by factors such as vertical elevation, season, hydrodynamics, and habitat age. Furthermore, these epifauna appear to be resilient to small temperature increases. These findings are important for understanding the linkages between primary producers and higher order consumers and for assessing system-wide productivity.

Summary: One of the biggest challenges in ecological risk assessment is determining the impact of multiple stressors on individual organisms and populations in real world scenarios. Metabolomic profiling provides an opportunity to address these uncertainties and accurately classify the effects of different stressors on the metabolism of non-target organisms. This study demonstrated that exposure to the insecticide carbaryl, predation stress, and a combination of both can significantly affect the metabolome and biochemical fluxes in post-metamorphosis southern leopard frogs.

Summary: This study used transcriptome-wide sequencing data to quantify the effects of multiple anthropogenic stressors on gene expression in the freshwater amphipod Gammarus fossarum. The results showed that stressor exposure led to the suppression of genes involved in metabolic and energy consuming cellular processes. The strongest transcriptional response was induced by increased salinity, which contradicted the observed abundance patterns. The interactions between stressors were mainly antagonistic.

Summary: This study investigated the impact of water and sediment quality on biotic communities using clustering analysis based on stress-response and geographical relationships. The results showed that the clustering based on Geo-SOM was the most effective in improving the performance of linear mixed-effect models. Phosphate and chlorophyll a were identified as the most influential water quality variables, while sedimentary phosphate and Cr were the most influential sediment quality variables.

Summary: In an era of climate change, the marine environment is experiencing impacts such as warming and ocean acidification. These effects are particularly significant in shallow coastal regions. This study investigates the impact of water temperature and pH on sperm characteristics and fertilization rate in sand dollars and sea urchins. It finds that both temperature and pH affect fertilization in sand dollars, while only temperature influences sperm swimming velocity and motility. The study suggests that environmental stressors like temperature and pH may impair aspects of the reproductive process beyond simple sperm swimming behavior.

Summary: Heat stress affects the fertility of dairy cattle, but supplementing vitamins E and coenzyme Q10 can alleviate its adverse effects on oocyte maturation and embryo development. Vitamin E was found to be more effective than vitamin C and coenzyme Q10 in improving maturation and cleavage rates, as well as increasing the count of blastocyst cells.
