Summary: Water temperature is a crucial factor affecting organismal growth and habitat use, and climate change is altering estuary temperatures. This study investigated the spatial and temporal patterns of water temperature in two estuaries and simulated the growth potential of juvenile Chinook salmon under present conditions and a climate warming scenario. The results showed that temperature distribution differed between the estuaries, leading to complex effects on salmon growth opportunities. While there was an overall increasing trend in growth potential with temperature warming, excessively high temperatures in late summer hindered growth potential. The vulnerability of estuaries and habitats to increasing temperatures also varied under climate change.

Summary: Fishing activities are vulnerable to climate change, especially in fishery-dependent coastal communities with low economic diversification. Adaptation measures, such as economic diversification, improvement in processing and commercialization of fishery products, and enhanced fisheries management, are crucial in reducing vulnerability to the impacts of climate change. Mexico has the policy framework in place for these measures, but requires financing and more efficient regulatory processes to address the rapid effects of climate change in marine systems.

Summary: Climate change and human activities have profound effects on marine ecosystem productivity, particularly impacting seabird breeding success, with stronger effects on fish-eating species in the northern hemisphere; hence, ocean management at hemispheric scales and targeted recovery plans are necessary. In the southern hemisphere, lower changes in seabird productivity provide opportunities for strategic management approaches like establishing large marine protected areas to sustain food webs and predator productivity.

Summary: Fisheries bycatch has global impact on marine species. This study investigates the influence of thermal and diel depth-use behaviors on the bycatch of a keystone species (Chinook salmon) in the largest fishery on the US West Coast. The results show that warmer sea surface temperatures and night time behavior of Chinook salmon contribute to increased bycatch rates. Furthermore, the effectiveness of a voluntary bycatch mitigation strategy varies depending on the sea surface temperatures and diel behaviors of the salmon.

Summary: Total dissolved gas (TDG) supersaturation, caused by sources such as hydroelectric dams, can lead to gas bubble trauma (GBT) in aquatic animals. Locomotion is hypothesized to promote bubble nucleation in fish tissues exposed to TDG supersaturation. This study aimed to understand the effects of locomotion on GBT in rainbow trout exposed to TDG supersaturation in static or flowing water conditions. The results indicate that there is no statistically significant difference in GBT occurrence between static and flowing water conditions.

Summary: The authors synthesized evidence to address methodological concerns and misconceptions surrounding the interpretation of critical thermal maximum (CTmax) in ecological and evolutionary studies of fishes. They highlighted the importance of considering factors that influence thermal limits when interpreting CTmax in ecological contexts. Applications of CTmax include mitigating the effects of climate change, informing infrastructure planning, and modeling species responses to temperature change. Future research directions aim to improve the application and interpretation of CTmax data in ecological contexts.

Summary: Despite major threats to humanity, evidence-based decision-making in environment management is relatively nascent. However, there is a growing number of environmental evidence syntheses available for decision-makers. Research is urgently needed to understand patterns and trends in environmental evidence use, and there is a need for reflection and sharing among those involved in producing and using evidence syntheses. It is hoped that these ideas will lead to further scholarship to enhance evidence-based decision-making and benefit the environment and humanity.

Summary: The use of plastic structures in freshwater ecosystems to enhance fish habitat or restore freshwater systems has become popular, but there are concerns about ecological benefits and potential pollution from plastic degradation. The evidence base for using plastic materials in these activities is limited, and there is a need to consider the full life cycle of restoration and potential environmental consequences. Natural materials should be embraced for habitat restoration, and stakeholders should have a say in material choices. Based on current evidence, the use of plastic for habitat enhancement or restoration in freshwater systems is littering.
