Summary: Reef-building corals, one of the most biodiverse and economically important ecosystems on the planet, are threatened by various natural stressors. Among them, ultraviolet radiation (UVR) has a double-edged impact on corals as it is a genotoxic stressor but also essential for their energy production. This systematic literature review investigates the physiological impacts of co-exposure to UVR and other stressors on corals. The results show that UVR generally exacerbates the negative effects of other stressors on corals. There are species-specific differences in tolerance to UVR and other environmental stressors, and the ambient levels of UVR can be beneficial. Future research should explore the interactions between UVR and other stressors, investigate the effects of multiple stressors on the coral microbiome, and examine the impacts of multi-stressors with UVR across early-life history stages.

Summary: The study found a mass dependence in the relationship between field metabolic rates and dynamic body acceleration, requiring coefficient corrections to account for estimation errors in differently sized individuals. Additionally, caution must be taken when applying predictive models developed on one size class to individuals of different sizes due to strong scale dependence in the relationship between metabolic rates and body acceleration.

Summary: Anthropogenic climate change and ecosystem disturbances have negative effects on habitats and species. Concentrated biodiversity areas, like aridland riparian zones, are particularly vulnerable. Understanding ecological and environmental relationships can improve conservation strategies. This study used visual transects and tape radio telemetry to study the behavior and spatial ecology of black-necked gartersnakes in a riparian zone of Arizona. They observed how external conditions, behavioral activity, and microhabitat usage were affected by environmental factors. The decline of black-necked gartersnakes and their response to disturbances highlight the importance of monitoring and managing species in changing ecosystems.

Summary: The ability of plants to adjust to climate change is crucial for their survival and carbon cycling. A comparative study of Eastern Mediterranean forests revealed that soil water content had the strongest influence on the seasonal patterns of carbon and water fluxes, while temperature and vapor pressure had milder effects. Aleppo pine forests exhibited a strong phenotypic adjustment potential, enhancing their survival and contribution to the carbon sink in the face of climate change in the region.

Summary: Biological rhythms influenced by external factors play a significant role in driving organism physiology, with studies on elasmobranchs suggesting that many species exhibit crepuscular or nocturnal behaviors. Research on metabolic rates in the epaulette shark indicates a diel pattern with low rates during the day and increased rates at night, influenced more by time of day than temperature. These findings suggest that certain species from tropical and coastal environments may have mechanisms in place to regulate metabolic rates seasonally irrespective of temperature fluctuations.

Summary: Taurine is essential for regulating cardiac contractility, and its deficiency can impair heart function in mammals. In rainbow trout, cardiac taurine levels vary between species and environmental changes can lead to reduced levels, impacting cardiac function. While taurine deficiency did not affect overall aerobic performance, it significantly impaired cardiac contractility in beta-alanine-fed trout.

Summary: Currently, there is limited understanding of the impacts of catch-and-release ice fishing on fish biology, including their physiology, behavior, and survival. Ice-angled fish face unique challenges, such as exposure to subzero temperatures and the use of different gear types. Cold environments may mitigate the stress response, but can also cause tissue freezing. Mortality rates after release can be influenced by gear type, barotrauma, and hooking location. Further research is needed to understand postrelease behaviors and the spatial ecology of ice-angled fish in order to inform management practices. Overall, investigating the consequences of winter catch-and-release angling is essential for developing effective guidelines and practices.

Summary: Differences in genomic architecture, such as chromosomal inversions, may play an important role in facilitating adaptation despite gene flow. A putative chromosomal inversion was found in walleye from Lake Winnipeg, indicating the potential for adaptive divergence between lakes despite high gene flow. However, the specific adaptive role of this inversion could not be determined with the present data.

Summary: Within Salmonidae, spawning and rearing in brackish water is rare. Early rearing in brackish-water environments increased the fish's ability to ionoregulate in elevated salinities. A study examined the impact of a freshwater or brackish-water rearing environment on salinity preference in lake trout using a dynamic choice experiment. Contrary to predictions, lake trout reared in freshwater selected higher salinity compared to those reared in brackish water.

Summary: With the continuous development of hydropower on a global scale, understanding the mechanisms and variables affecting fish stranding in hydropeaking rivers is crucial. This study examined fish stranding in the Saskatchewan River, Canada, using remote photography and transect monitoring. The results showed that juvenile sport and commercial fish species were more susceptible to stranding. Remote photography provided precise timing of stranding events and linked them to environmental and physical conditions. The comparison of the two methods revealed similar stranded fish densities, but remote photography allowed for continuous observations. The study also found that water temperature and substrate particle size influenced the probability of fish stranding. Overall, these findings have important implications for managing hydroelectric flow and understanding the impacts on fish communities.

Summary: The acclimatization of certain ectothermic vertebrates to winter conditions involves reduced energy consumption, achieved through decreased movement activity, depression of cellular functions, or switching to anaerobic energy production. This study on crucian carp showed that winter-acclimatized fish exhibited lower metabolic rates and a shift to anaerobic energy production during anoxia. Winter dormancy in crucian carp is achieved through active reduction of energy consumption, a slowed metabolic rate, and a direct response to oxygen absence.

Summary: According to life-history theory, there might be different immunological strategies between reproductive and non-reproductive periods due to limited resources. Our study on two sympatric marine fish species, rockfish and sandperch, found that reproductive individuals showed lower immune function, but higher levels of natural antibodies in rockfish females, compared to their non-reproductive counterparts. On the other hand, reproductively active sandperch males showed lower levels of natural antibodies and higher neutrophil to lymphocyte ratio and spleen index compared to non-reproductive males. The study highlights the species-specific patterns of immunity and the potential influence of resource limitation and abiotic factors on immune trade-offs in fish.
