Cooperation may emerge from intrinsic factors such as social structure and extrinsic environmental conditions. Although these might reinforce or counteract each other, their interaction remains unexplored in animal populations. Studies on multilevel societies suggest a link between structure, conditions individual investment cooperative behaviours. These exhibit flexible configurations, with stable groups that overlap associate hierarchically. Structure can be seasonal, upper-level units appearing only during specific seasons, lower-level persisting year-round. This offers an opportunity to investigate how cooperation relates Here, we study the seasonal society of superb fairy-wrens ( Malurus cyaneus ), observing responses experimental playback conspecific distress calls. Individuals engaged more helping behaviour less aggressive/territorial song harsher non-breeding season compared breeding season. The increase was greater for group members than same community, upper unit, comprised distinct association. Results drives switch cooperation, supporting hypothesis harsh

ABSTRACT Anthropogenically induced climate change has significantly increased the frequency of acute weather events, such as drought. As human activities amplify environmental stresses, animals may be forced to prioritize survival over behaviors less crucial immediate fitness, socializing. Yet, social bonds also enable individuals deleterious effects conditions. We investigated how highly plains zebra ( Equus quagga ) modify their activity budgets, networks, and multimodal communication during a Although prioritized feeding number interactions dramatically decreased in late drought period, associations remained robust. observed age/sex class‐specific changes behavior, reflecting nutritional needs niche each individual. Stallions devoted more time greeting behaviors, which could mitigate harassment by bachelor males facilitate grazing for females harem. Juveniles spent active socializing, despite mothers showing greatest decrease interactions. Instead, unrelated, nonlactating served partners, accommodating both juveniles' lactating mothers' nutritive requirements. Using network‐based representation communication, we signals used Individuals diverse combinations, particularly costly context aggression. These findings illustrate roles differential responses stress within stable groups contribute species resilience, flexibly responds sociality under harsh
