Prey may gain fitness benefits from recognizing predators at an early age. Predator cues perceived by gravid prey have the potential to prime offspring to alter their behaviour in the presence of predation threats after birth. Wolf spiders (Araneae:

Large groups of animals aggregate around resource hotspots, with group size often influenced by the heterogeneity of the environment. In most cases, the foraging success of individuals within groups is interdependent, scaling either constructively or

Leaving the nest is a key transition in the life of altricial birds, whereby fledging decisions should depend on multiple factors, including the risk of predation. High postfledging predation risk may favour fledging at a more advanced stage of devel

Strategies that mitigate predation, whether proactive or reactive, can nevertheless impose significant ‘nonconsumptive’ costs on prey species. Here we used data from two wild vervet monkey, Chlorocebus pygerythru,s groups to assess whether the de

Animal architecture is diverse in form and structure, and extraordinarily intricate, often facilitated by the collective behaviour of several individuals. Social spider webs are one such example of animal architecture, robustly supporting the collect

Foraging dives in birds and mammals involve complex physiological and behavioural adaptations to cope with the breaks in normal respiration. Optimal dive strategies should maximize the proportion of time spent under water actively foraging versus the

Small birds in winter face trade-offs between predation risk and foraging, and alternate life-history strategies may arise from these trade-offs. Animal personality shows similarities with alternative life-history strategies, and using a life-history

Territorial threat is costly and variable across contexts and behavioural flexibility is favoured to maximize any cost/benefit ratio. This is well illustrated in how animals react to familiar or unfamiliar outgroup members. In some situations, neighb

Variation in behavioural traits is especially important in novel habitats where selection forces determine successful colonizers. Prey species must constantly balance the risk versus reward of remaining in an area with threats while gaining possible

Synchronous digging activity and emergence from underground nests is important for sea turtle hatchlings, as it reduces predation risk and decreases energy consumption. However, patterns of underground hatching and diel digging activity prior to emer
