Summary: The experiment found that sockeye salmon collected closer to the river entrance had less severe infections compared to those collected further upstream, likely due to differences in migration distance. Higher temperatures had a significant negative impact on the longevity of river-collected fish, while the effect on marine-collected fish was less significant. Cumulative stressors were detrimental to all fish, possibly due to extreme physiological disturbance.

Summary: Understanding the transmission of viruses between host populations is crucial for developing strategies to control viral diseases. This study identified three transmission links associated with the emergence of IHNV in coastal Washington steelhead trout populations between 2007 and 2011, providing insight into the virus movement from source to recipient populations. The findings suggest at least three introductions of virus from Columbia fish to coastal fish, with infected juvenile fish in the Columbia region being the likely source and adult fish returning to coastal hatcheries as the first detected recipient populations. Variations in timing and distance of these transmission links highlight the complexity of IHNV transmission routes.

Summary: The frequency and severity of extreme thermal events and disease outbreaks are predicted to continue shifting due to global change. Host species' persistence increasingly depends on the interaction between thermal stress and pathogen exposure. Infection can directly disrupt a host's ability to cope with thermal stress, and various sources of variation in host thermal performance must be considered when assessing species vulnerability and disease spread during extreme thermal events.

Summary: Through comparing three mangrove systems in the Colombian Pacific with different levels of anthropogenic intervention, this study found that higher levels of anthropogenic intervention can lead to decreased diversity and modifications in the trophic structure of tropical mangrove fish communities. The results indicate that high anthropogenic intervention levels result in lower abundance and species numbers, as well as an increase in isotopic niche width, suggesting a decrease in availability of prey and basal resources.

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.
