Summary: Multiple stressors such as climate change, eutrophication, and pesticide contamination have caused a decline in lake zoobenthos, impacting energy dynamics, nutrient cycling, and sediment degradation. These stressors decrease zoobenthos abundance and diversity, resulting in changes in species composition and structure. Eutrophication increases abundance but reduces taxonomic diversity, while climate change affects species adaptability to temperature changes. Pesticides like imidacloprid negatively affect zoobenthos survival and growth. However, the interactions between imidacloprid and other stressors are not well-studied.

Summary: While research has extensively explored the physiological effects of multiple environmental stressors, the role of behavioural and life-history plasticity in mediating these effects has been neglected. This study presents a conceptual framework that links animal behaviour to energy allocation pathways, elucidating the impact of multiple stressors on fitness. The framework highlights how small-scale behavioural changes and trade-offs in energy allocation and escape strategies contribute to the complex effects of stressors on organisms. Considering animal behaviour in stressor research can enhance our understanding and inform future studies.

Summary: Eutrophication, climate change, water level fall, fish introduction, and salinity have impacts on lake ecosystems. This study investigates the long-term trends in a brackish lake in China in response to these environmental stressors. The findings show that trophic level is the main driver of diatom assemblage changes, and other environmental variables also contribute to diatom community variation.

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 study assesses the impact of various stressors on the biodiversity of Mediterranean coastal wetlands. It finds that eutrophication and chemical pollution are the most studied stressors, while temperature rise and species invasions are less represented. Most studies show direct or indirect effects of these stressors on primary producers and invertebrate communities, leading to changes in species dominance patterns and a decline in endemic populations. Few studies have addressed stressor interactions, highlighting the need for further research to guide ecosystem management and restoration measures.

Summary: This study emphasizes the importance of considering not only climate refugia, but also other stressors such as human-induced changes in fire and hydrology, for conservation efforts. The authors introduced a new conceptual approach called "domains of refugia" to assess refugial capacity and identify areas with low exposure to multiple stressors. Results suggest that areas with high refugial capacity may be underrepresented in existing protected area networks, highlighting the need for expanding conservation efforts.

Summary: Through a statistical framework using linear mixed models (LMMs), the study found that water quality in nearshore areas of large lakes is influenced by multiple factors, with geographic proximity to shoreline tributaries and stormwater drains being the most important drivers for parameters such as phosphorus concentration. This framework highlights how individual nutrient sources can be distinguished from climate factors within dominant nearshore-offshore gradients in water quality within large lake ecosystems.

Summary: The study conducted experiments to investigate the toxic effects of chlorpyrifos and dichlorvos mixture on common carp, with findings that chlorpyrifos had higher toxicity to the species and the toxic effects of the mixture were dominated by synergism. The exposure of fish to sub-lethal concentrations of the pesticides and their mixture resulted in increased buccal movements and oxygen uptake, along with feeding depression, suggesting that joint toxicity assessment is crucial for realistic water quality standards and monitoring guidelines.

Summary: This study investigates the distribution of metals and metalloids in water, sediment, and fish tissues of Lake Hawassa in Ethiopia and assesses the resulting health and ecological risks. The results show that the metal concentrations in water do not have a potential adverse effect on aquatic life, but certain metals exceed the probable effect concentration in sediment, suggesting potential toxicity to aquatic organisms. Fish store more metals in their liver than in their muscle, and different fish species have varying levels of metal accumulation. Positive correlations among metals in water and sediment indicate a potential common pollution source.

Summary: Protective responses are crucial for organismal persistence in complex environments. Cross-protection, the phenomenon where encountering one stressor enhances tolerance to another stressor, has been observed in diverse taxa and habitats. This Commentary discusses the mechanistic basis and adaptive significance of cross-protection, advocating it as a "pre-adaptation" to a changing world. The longevity of cross-protection responses and associated costs should be quantified for more accurate predictions of species' responses to complex environments.

Summary: Nitrogen-based fertilizers can increase agricultural yields but also pose the risk of water contamination. This study found that chronic exposure to nitrate can reduce growth rates and body sizes in southern bell frogs during their early life stages. However, the observed impairments were not associated with changes in heart rate or metabolic rate, suggesting other mechanisms are involved. These results highlight the vulnerability of L. raniformis to nitrate exposure during early life.
