| 1 | The effect of white noise on behavioral and flight responses of blue-tailed skinks显示文摘As human development expands,environments are increasingly exposed to anthropogenic noise which may disrupt animals in a variety of ways.Anthropogenic noise can be disruptive both as a source of auditory masking,which prevents animals from acquiring acoustic information(Brumm and Slabbekoorn 2005),or as a source of distraction,reallocating an individual's attention and impairing an animal's ability to engage in critical behaviors such as prey risk assessment(Chan et al.2010). | Connor KELLIGREW Sarah TIAN Marcus WeISS Dana M.WILLIAMS Daniel T.BLUMSTEIN | 2021 | Current Zoology2021，67，1： | 0 |
| 2 | High human disturbance decreases individual variability in skink escape behavior显示文摘Animals living around people may modify their antipredator behavior as a function of proximity to humans,and this response has profound implications for whether or not a population can coexist with humans.We asked whether inland blue-tailed skinks Emoia impar modified their individual antipredator behavior as a function of differential exposure to humans.We conducted multiple consecutive flushes and recorded 2 measures of antipredator response:flight initiation distance(FID),the distance from a threatening stimulus at which an individual flees,and distance fled,the distance an individual fled after a flush.We used a multiple model comparison approach to quantify variation in individual escape behavior across multiple approaches and to test for differences in between-individual variation among populations.We found that individuals tolerated closer approach and fled shorter distances at locations with relatively less human disturbance than at locations with medium and high human disturbance,respectively.In addition,skinks living at high human disturbance sites had less variable FIDs than at low human disturbance sites.Two theories may explain these results.Selection against less favorable phenotypes has reduced behavioral variation in urban habitats and behavioral plasticity allows individuals to flexibly adjust their behavioral patterns in response to human disturbance.These results highlight the importance of studying variation within populations,at the individual level,which may better elucidate the impact that human disturbance has on the behavioral composition of populations. | Dana M.WILLIAMS Phat-Tan NGUYEN Kemal CHAN Madeleine KROHN Daniel T.BLUMSTEIN | 2020 | Current Zoology2020，66，1： | 0 |
