Background: Urbanization is rapidly changing our planet and animals that live in urban environments must quickly adjust their behavior. One of the most prevalent behavioral characteristics of urban dwelling animals is an increased level of risk-taking. Here, we aimed to reveal how urban fruitbats become risk-takers, and how they differ behaviorally from rural bats, studying both genetic and non-genetic factors that might play a role in the process. We assessed the personality of newborn pups from both rural and urban colonies before they acquired experience outdoors, examining risk-taking, exploration, and learning rates.

Results: Urban pups exhibited significantly higher risk-taking levels, …

Hurricane Irma Induces Divergent Behavioral And Hormonal Impacts On An Urban And Forest Population Of Invasive Anolis Lizards: Evidence For An Urban Resilience Hypothesis, Haralambos Fokidis, Taylor Brock

Hurricanes can have both profound short-term effects on animal populations and serve as long-term drivers of evolutionary change. Animals inhabiting varying habitats may differ in their response to hurricane impacts. Increasing evidence sug- gests that animals from urban areas exhibit different behavioral and physiological traits compared to rural counterparts, in- cluding attenuated hormonal stress responses and a lowered propensity for flight behavior. A unique opportunity was pre- sented when Hurricane Irma hit Florida on 10 September 2017 and interrupted a study of invasive brown anoles (Anolis sagrei) at an urban and a forest. Using data collected before and after Hurricane …
