We found that both stressors had a strong influence on the appearance of prey (objectively quantified as the mean magnitude of the optical flow in the videos). As expected, turbidity reduced the frequency of detection between the guppies and the simulated predator, ie the magnitude of optical flow exceeded the threshold for a \"detection event\" more often in clear water. Events were also shorter in duration in turbid water, reducing the time available for a predator to detect the prey. However, during an event, prey were more detectable in warmer water (ie the mean magnitude was greater).

This raises the question: why do breeders tolerate non-breeders in such societies? Here, we test the hypothesis that breeders of the clown anemonefish (<i>Amphiprion percula</i>) will tolerate non-breeders because they are distant relatives who go on to inherit the territory. We use 40 polymorphic microsatellite loci to assess the pairwise relatedness of 683 individuals from 203 groups. We show that the mean pairwise relatedness among individuals from the same group is effectively zero, and no different from that found among individuals from the same reef or that found among individuals from the population at large. Further, we show that the mean pairwise relatedness found among breeder/breeder dyads is no different from that found among breeder/non-breeder dyads or that found among non-breeder/non-breeder dyads.

Significant differences in plant-pollinator community structure were also observed, with Diptera most abundant under low wind conditions, and Hymenoptera predominant and Lepidoptera absent in windier conditions.

To better understand the effect of noise on avian communication, we investigate whether robins modify their non-breeding song in noisy environments. We analyed the autumn songs of 25 robins exposed to varying background noise levels and found that robins increase the minimum frequency of their songs and extend phrase duration by singing fewer but longer syllables per phrase in noisy environments-adjustments that may mitigate acoustic masking. Our results provide valuable insights into the broader impact of urbanization on bird communication and highlight the need to consider non-breeding vocal behavior in conservation efforts. These findings underscore the year-round impact of noise pollution on birdsong, suggesting it affects various aspects of avian life history. However, it remains unclear whether these adjustments have evolutionary consequences for survival, as changes in key song parameters may affect how rivals interpret signals.

Here, we investigate whether heatwaves impact cognition using male guppies (<i>Poecilia reticulata</i>) as a vertebrate model. We focused on males due to their behavioral consistency in cognitive tests and because they were previously observed to alter sexual behavior after a heatwave. Males were exposed to a 5-d experimental heatwave (32 °C) or control treatment (26 °C). The chosen temperatures are ecologically relevant for the species, fall within their natural habitat's thermal range, and reflect extreme climatic events that are projected to become even more frequent and severe under future climate scenarios. Following treatment, all fish were tested at 26 °C for spatial memory and learning, mate choice, inhibitory control, and anti-predator responses. We also conducted histopathological evaluations of brain tissue to investigate potential central nervous system lesions. The results show that heatwave exposure declined maze solving efficiency, affected mate choice-related cognitive capacities, and led to suboptimal anti-predatory responses. No effects were observed on inhibitory control or habituation. Importantly, heatwave exposure induced morphological alterations in the central nervous system, potentially explaining the observed changes in cognitive performance.
