Data and R codes from: Effects of human disturbance on risk-taking behavior in painted turtles
<p>Animals are exposed to high levels of anthropogenic disturbance, which has profound consequences for population persistence. Individuals can adjust their behavior plastically when faced with perturbations in their environment and may show consistent differences in the way they perceive and respond to risky situations. Over time, this variability among individuals in response to risk can affect the dynamics of populations exposed to human disturbance. Thus, understanding how animals cope behaviorally with human disturbance is important, especially for species vulnerable to human perturbations, such as turtles. In this context, we evaluated whether risk-taking behaviors are consistent within individual painted turtles (<em>Chrysemys picta</em>) and assessed how these behaviors are related to the extent of human disturbance along the Rideau Canal, Ontario, Canada. Specifically, we conducted repeated measurements of the number of active defensive behaviors used during handling and the time taken to escape a floating platform for a total of 730 painted turtles (1117 observations) from 22 sites varying in human disturbance along the canal. We also quantified the emergence of the turtles from the water after escaping the platform. First, individual painted turtles showed consistent differences in all risk-taking behaviors. Second, painted turtles in areas with high boat activity displayed more active defensive behaviors, while turtles from sites in proximity to more houses with access to the canal used fewer. Our study highlights the importance of studying animal behavior to better understand the impact of human activities on animal populations.</p>

Data and R code for: Handling- or digestion-limited predator: the role of body masses and habitat complexity in predator-prey feeding interaction
<p><span>Predator functional response is a key element of feeding interactions that quantify the per capita feeding rates of predators depending on prey density, and variation in its parameters is strongly associated with interaction strength and population dynamics. We studied 18 functional responses of the marine whelk-bivalve systems across three levels of predator body size and three prey species at two habitat structures. We found that the marine whelk can be a handling-limited predator which received less attention so far. We propose that the handling-limited predator can further be categorized into two types: pursuing-limited (where maximum feeding rate could be influenced by habitat complexity) and ingesting-limited (where maximum feeding rate is impacted not by habitat complexity, but predator-prey body mass ratios and prey defense strategy). Our results show that handling time scales negatively with predator-prey body mass ratios, but there are layers of complexity nested within this trend. We first provide an underlying mechanism of this trend is the transition from handling to digestion limitation with increasing predator-prey body mass ratios. In addition to confirming known body mass ratios and habitat structure effects, our study confirms the importance of prey types. Our study reveals that simple assumptions about body masses and prey defense strategy may usefully refine estimates of feeding interactions in complex food webs.</span></p>
