- Abstract:
- ... The sensory drive hypothesis proposes that natural selection on certain behaviours will alter sensory system properties and result in correlated evolution of unrelated behaviours reliant on that sensory system. Here, we used artificially selected populations to demonstrate that selection on colour-based foraging behaviour is associated with divergence of male sexual display behaviour. In a previou ...

- Abstract:
- ... Animals may modify their behaviour towards conspecifics to manage social conflict that arises due to group living. Given that social conflict is likely to vary through space, we would expect individuals to adjust their social behaviour, accordingly, across their home range. This, however, remains to be explicitly investigated. Here, we used a longitudinal behavioural data set on eastern water drag ...

- Abstract:
- ... Animals are equipped with sophisticated guidance systems that enable them to navigate efficiently. Previous studies suggest that foraging animals such as desert ants tend to combine guidance systems in a weighted manner, where the weight given to each cue gradually changes during the approach to the goal. However, when subjected to rapid enforced decision making (e.g. under predation risk), the an ...

- Abstract:
- ... Material and/or genetic benefits are hypothesized to be the main drivers of female mate choice. Research on female mate choice has mainly focused on polyandrous species and has seldom considered monandrous species. Given the absence of postcopulatory mate choice in monandrous females, we predicted that precopulatory mate choice is important for monandrous species. Using the wolf spider Pardosa ast ...

- Abstract:
- ... In group-living species, encounters with extragroup rivals can be one of the riskiest actions in which individuals participate. Different group members often have different incentives to participate during intergroup interactions, and individuals with fewer payoffs of competition, including those of the smaller sex and/or lower rank, may ‘free-ride’ to avoid the costs of conflict. However, there i ...

- Abstract:

Understanding the evolution and maintenance of social behaviour requires a better understanding of the physiological mechanisms underlying the trade-offs between the benefits and costs of social status. Social dominance is expected to provide advantages in terms of access to resources and to reproduction but acquiring and maintaining dominance may also entail physiological costs. Dominant individu ...

- Abstract:
- ... Imperfect mimicry presents a paradox of incomplete adaptation – intuitively, closer resemblance should improve performance. Receiver psychology can often explain why mimetic signals do not always evolve to match those of their models. Here, we explored the influence of a pervasive and powerful cognitive bias where associative learning depends upon an asymmetric interaction between the cue (stimulu ...

- Abstract:
- ... Lateralization refers to the preferential use of one side of the body to perform certain tasks, often as a consequence of the specialization of cerebral hemispheres. Individuals may benefit from lateralization if it allows them to perform complex tasks simultaneously. Studies on laterality further suggest that sex and age can influence the extent of lateralization. However, most studies on lateral ...

- Abstract:
- ... Signalling is energetically expensive and increases the risk of predation and parasite infection. To balance the costs and benefits of mate attraction, individuals may adopt an alternative mating strategy such as satellite behaviour, in which nonsignalling males will settle near signalling males and attempt to intercept approaching females. While many suggest that alternative strategies are ‘makin ...

- Abstract:

The ‘positive allometry hypothesis’ predicts that ornaments and weapons of sexual selection will scale steeply when among-individual variation in trait size is compared with variation in overall body size. Intuitive and striking, this idea has been explored in hundreds of contemporary animal species and sparked controversy in palaeobiology over the function of exaggerated structures in dinosaurs a ...

We predicted that the ability to gather information about predator presence through chemical cues might be particularly important for ground-living and foraging bird species, since their main predators, namely mammals and reptiles, use chemical communication. In this context, we experimentall ...

- Abstract:
- ... Most hosts of the parasitic brown-headed cowbird, Molothrus ater, demonstrate an astonishing lack of defences against parasitism, typically explained by evolutionary lag. We investigated antiparasite strategies of the dickcissel, Spiza americana, whose apparent acceptance of parasitism is unlikely to be explained by lag because its historic centre of abundance overlaps with that of the cowbird.

Much of the research on behavioural background matching has been conducted on species with fixed coloration and body patterns, while less is known about the role background choice plays in species capable of rapid (within minutes or seconds) colour change ...

Recently we have found that when prospecting for nests, brood-parasitic female cowbirds (Molothrus ater) vary in their use of personal and social information when selecting a nest (White, Davies, Agyapong, & Seegmiller, 2017, Proceedings of the Royal Society B: Biological Sciences, 284, 1–8), with females that are most accurate at using personal information relying least on social information and ...

Behavioural flexibility, the ability to adjust behaviour to environmental change by adapting existing skills to novel situations, is key to coping with, for example, complex social interactions, seasonal changes in food availability or detecting predators.

- Abstract:

Thus, the direction and intensity of sexual selection should be affected by thermal conditions. However, the effects of temperature variation during mating events have sometimes been overlooked. We assessed traits associated with pre- and postcopulatory sexual selec ...
