“…Droughts can further increase the severity of heat stress because reduced water availability constrains thermoregulation (Sannolo & Carretero, 2019; Veldhuis et al, 2019; Rozen‐Rechels et al, 2020), and dehydration itself causes cognitive impairment (Santollo et al, 2019). Acidification interacts with warming in affecting cognitive performance and behavioral responses of marine animals (Nagelkerken & Munday, 2016; Domenici et al, 2017; Laubenstein et al, 2019). CO 2 levels in line with end‐of‐century projections can impair the ability to discriminate predator cues (Dixson et al, 2010), slowing reaction times (Allan et al, 2013; Jutfelt et al, 2013), and increasing mortality in the wild (Munday et al, 2010).…”

With global surface air temperature rising rapidly, extensive research effort has been dedicated to assessing the consequences of this change for wildlife. While impacts on the phenology, distribution, and demography of wild animal populations are well documented, the impact of increasing temperature on cognition in these populations has received relatively little attention. Cognition encompasses the mental mechanisms that allow individuals to process information from the surrounding environment, respond accordingly, and flexibly adjust behavior. Hence, it is likely to be a key factor in allowing animals to adjust adaptively to climate change. Captive studies show that heat stress can negatively affect cognitive performance not only in the short‐term but also in the long‐term, by altering cognitive development at early life stages. Field studies indicate that cognitive performance may affect survival and reproductive success. However, the link between heat stress, cognition, and fitness in wild animals has yet to be formally established. We propose a comprehensive research framework for the collection of robust empirical datasets on heat stress and cognitive performance in the wild. We then suggest how knowledge of heat stress impacts on cognitive performance could be applied to population viability models and wildlife management actions. We believe that a joint research effort encompassing the fields of thermal physiology, behavioral ecology, comparative cognition, and conservation science, is essential to provide timely mitigation measures against the potential impacts of climate change on wildlife.

“…Exposure to elevated CO 2 has shown to alter important behaviors, such as navigation, habitat selection, learning and predator-prey interactions in some fish (Nagelkerken and Munday, 2016;Munday et al, 2019;Paula et al, 2019;Williams et al, 2019) and invertebrates (Watson et al, 2013;Jellison et al, 2016). For example, exposure to elevated CO 2 impairs the natural avoidance behavior of chemical alarm cues (CAC) in some fishes (Ferrari et al, 2011;Chivers et al, 2014;Welch et al, 2014;Ou et al, 2015;Welch and Munday, 2017;Laubenstein et al, 2019). Chemical alarm cues are compounds released from the skin of injured fishes, thereby providing a reliable cue of immediate predation threat (Ferrari et al, 2009).…”

Elevated CO 2 levels predicted to occur by the end of the century can affect the physiology and behavior of marine fishes. For one important survival mechanism, the response to chemical alarm cues from conspecifics, substantial among-individual variation in the extent of behavioral impairment when exposed to elevated CO 2 has been observed in previous studies. Whole brain transcriptomic data has further emphasized the importance of parental phenotypic variation in the response of juvenile fish to elevated CO 2 . In this study, we investigate the genome-wide proteomic responses of this variation in the brain of 5-week old spiny damselfish, Acanthochromis polyacanthus. We compared the accumulation of proteins in the brains of juvenile A. polyacanthus from two different parental behavioral phenotypes (sensitive and tolerant) that had been experimentally exposed to short-term, long-term and inter-generational elevated CO 2 . Our results show differential accumulation of key proteins related to stress response and epigenetic markers with elevated CO 2 exposure. Proteins related to neurological development and glucose metabolism were also differentially accumulated particularly in the long-term developmental treatment, which might be critical for juvenile development. By contrast, exposure to elevated CO 2 in the parental generation resulted in only three differentially accumulated proteins in the offspring, revealing potential for intergenerational acclimation. Lastly, we found a distinct proteomic pattern in juveniles due to the behavioral sensitivity of parents to elevated CO 2 , even though the behavior of the juvenile fish was impaired regardless of parental phenotype. Our data shows that developing juveniles are affected in their brain protein accumulation by elevated CO 2 , but the effect varies with the length of exposure as well as due to variation of parental phenotypes in the population.

“…Studies on species exposed to wider thermal ranges are more scarce. Reproduction performance is an important part of fish development and it is then crucial to understand the impacts of multiple stressors such as pH and temperature in cross-factorial studies 28,44 . Out study shows that exposure to extreme present conditions of temperature and pH already have negative effects on multiple aspects of reproduction.…”

Fish reproductive success is linked to the ability of couples to mate and produce clutches that successfully hatch. Environmental stressors like high temperature and low pH can jeopardize this energetically costly process. In this study, exposure to high temperature and low pH was tested on a marine temperate species, Gobiusculus flavescens, to evaluate effects on reproductive performance. Breeding pairs were assigned to different temperatures (+ 0 °C, + 3 °C relative to in situ temperature) and pH levels (8.0, 7.6), in a cross-factorial design for a 3-month period. Reproduction activity, success, and paternal investment were measured throughout the exposure period. Results show reproduction is impaired by elevated temperature, while low pH had little impact. Breeding pairs under high temperature had 3% to 10% hatching success, up to 30% less eggs and eggs up to 20% smaller. Although paternal investment was not affected by tested parameters, males of breeding pairs exposed to elevated temperature had smaller gonadosomatic indexes, which might indicate a lack of investment in the reproductive process. Overall, results show that elevated temperature, expected more frequently in the near future, as a consequence of global warming, may impair key processes like reproduction in temperate fish, with potential consequences for fitness and population replenishment.
