Recognizing form and function of animal defenses is paramount to understanding the ecological and evolutionary forces behind predator and prey dynamics. Color patterns are strongly related to defensive strategies in animals. Some rely on camouflage to avoid detection, while others are brightly colored and conspicuously signal their noxiousness to potential predators. Still others combine cryptic dorsal...
Among various environmental factors, temperature has been considered a main determinant of outcomes of predator–prey interactions involving ectotherms. Although numerous studies have aimed to examine temperature effects on those interactions, few studies have been conducted under fully natural conditions. In this study, we examined the degree to which temperature affects the outcomes of encounters...
Anthropogenic sources of environmental pollution are ever‐increasing as urban areas expand and more chemical compounds are used in daily life. The stimulant caffeine is one of the most consumed chemical compounds worldwide, and as a result, has been detected as an environmental contaminant in all types of major water sources on all continents. Exposure of wildlife to environmental pollutants can disrupt...
In long‐lived monogamous species, the trigger of costly re‐pairing is not always clear. Limited research suggests that within‐pair behavioural compatibility may be an important driver of partnership success, as cooperation should be enhanced when pair members' decisions complement one another. Animals' decision‐making processes are influenced by personality traits – defined as individual differences...
A defining feature of parasitism is the harm parasites cause to their host via a reduction in lifetime reproductive success. Harm, also referred to as “virulence,” may involve host mortality or sublethal effects, such as a decreased body condition or protracted development of immature individuals. We considered a system where colonies of the social spider Anelosimus eximius serve as hosts to confamilial...

Animals evolve in complex selective regimes, where a suite of different factors can shape signal use. We might predict that more closely related species will exhibit more similar behavior than those more distantly related; however, sometimes signals are shaped more profoundly by the environment or other forces. Lizards in the genus Sceloporus communicate with conspecifics with multimodal signals that...
