Data from: Predation risk perception, food density and conspecific cues shape foraging decisions in a tropical lizard
When foraging, animals can maximize their fitness if they are able to tailor their foraging decisions to current environmental conditions. When making foraging decisions, individuals need to assess the benefits of foraging while accounting for the potential risks of being captured by a predator. However, whether and how different factors interact to shape these decisions is not yet well understood, especially in individual foragers. Here we present a standardized set of manipulative field experiments in the form of foraging assays in the tropical lizard Anolis cristatellus in Puerto Rico. We presented male lizards with foraging opportunities to test how the presence of conspecifics, predation-risk perception, the abundance of food, and interactions among these factors determines the outcome of foraging decisions. In Experiment 1, anoles foraged faster when food was scarce and other conspecifics were present near the feeding tray, while they took longer to feed when food was abundant and when no conspecifics were present. These results suggest that foraging decisions in anoles are the result of a complex process in which individuals assess predation risk by using information from conspecific individuals while taking into account food abundance. In Experiment 2, a simulated increase in predation risk (i.e., distance to the feeding tray) confirmed the relevance of risk perception by showing that the use of available perches is strongly correlated with the latency to feed. We found Puerto Rican crested anoles integrate instantaneous ecological information about food abundance, conspecific activity and predation risk, and adjust their foraging behavior accordingly.
Data from: Sex differences in risk perception in deep-diving bottlenose dolphins leads to decreased foraging efficiency when exposed to human disturbance
1. Individuals make behavioural decisions by weighing potential advantages and costs (e.g. increased food intake vs. increased risk of predation). When animals change their activities in response to a perceived threat, their energetic input may decline. Marine ecotourism, including whale and dolphin watching, is growing globally and cetaceans perceive interactions with tour vessels as a form of risk. Observable behavioural changes need to be linked to bioenergetic effects to determine the potential population consequences of this disturbance. 2. We developed a theoretical optimal dive model for bottlenose dolphins under three potential types of perceived risk resulting from human interactions at the surface (decreasing instantaneous risk, increasing instantaneous risk and no risk). We compared the predictions of these theoretical models to observed dive cycles of foraging male and female dolphins in the presence and absence of tour vessels. We used mixture models to classify dive types and mixed effects models to analyse changes in the interbreath interval of surface and bottom dives and the frequency of estimated bottom dives. 3. Males significantly increased bottom time and performed fewer bottom dives when boats were present, matching predictions of our theoretical model for perceived decreasing instantaneous risk. In contrast, females significantly decreased bottom times and increased the frequency of bottom dives, matching predictions from the model for perceived increasing instantaneous risk. Therefore, our empirical results suggest differences in the perception of risk between sexes. 4. Synthesis and applications. By comparing theoretical predictions with observed dive data, our study suggests that boat interactions during foraging can cause decreased net energy gain over a foraging bout for both sexes, with females being more impacted. The population under study is currently listed as critically endangered. Understanding whether these predicted energetic impacts affect an individual's vital rates will provide a link to the population-level consequences of this disturbance. Previous analytical approaches have failed to capture the costs associated with disturbance during foraging, leading to management recommendations that only protect animals from increased energetic expenditure. We suggest that the current management scheme should be revised to include foraging areas in order to secure the energy intake of animals.

The effect of perceived crowding on risk perception in leisure sports: Based on Edward T. Hall's concept of "proxemics"
<p class="MsoNormal"><span>This study aims to identify how we can prevent the spread of infectious diseases and examines the social distancing required for participants in leisure sports activities to safely enjoy these activities. Based on crowdedness and risk perception in spaces perceived by people today, the above is investigated in terms of distance in Edward T. Hall's concept of proxemics. The study subjects are people aged 20</span><span>–</span><span>65 who used spaces for leisure sports during the COVID-19 pandemic in South Korea. An online survey was conducted from September 20 to October 20, 2021, and data from a total of 391 participants were used for the final analysis. Measures of perceived crowding, risk perception, and Edward T. Hall's proxemics were used as the tools after modifying and validating them. The results showed that perceived crowding according to space for leisure sports activities during the COVID-19 pandemic affected individual risk perception in indoor leisure sports and social risk perception in outdoor leisure activities. Perceived crowding according to proxemics influenced personal, social, and public distance in individual risk perception and public and social distance in social risk perception. Therefore, it is necessary to re-examine the scope of social distance in perceiving risk perception and reducing the crowdedness of participants in leisure sports activities to prevent the spread of infectious diseases like COVID-19. Moreover, individuals must make efforts to maintain a minimum distance from others. Further, media education and warning messages must be disseminated to prevent infection and reduce crowding.</span></p>
