Thermoregulation constrains effective warning signal expression.
Evolution of conspicuous signals may be constrained if animal coloration has nonsignaling as well as signaling functions. In aposematic wood tiger moth (Parasemia plantaginis) larvae, the size of a warning signal (orange patch on black body) varies phenotypically and genetically. Although a large warning signal is favored as an antipredator defense, we hypothesized that thermoregulation may con...
متن کاملBehavioral thermoregulation in lizards: importance of associated costs.
The Puerto Rican lizard Anolis cristatellus behaviorally regulates body temperature in an open habitat but passively tolerates lower and more variable temperatures in an adjacent forest where basking sites are few and distant. Thermoregulation may be adaptive only when costs resulting from associated losses of time and energy are low.
متن کاملColor Change for Thermoregulation versus Camouflage in Free-Ranging Lizards.
Animal coloration has multiple functions including thermoregulation, camouflage, and social signaling, and the requirements of each function may sometimes conflict. Many terrestrial ectotherms accommodate the multiple functions of color through color change. However, the relative importance of these functions and how color-changing species accommodate them when they do conflict are poorly under...
متن کاملOptimal foraging constrains macroecological patterns: body size and dietary niche breadth in lizards
Aim To explore and identify probable mechanisms contributing to the relationships among body size, dietary niche breadth and mean, minimum, maximum and range of prey size in predaceous lizards. Location Our data set includes species from tropical rainforests, semi-arid regions of Brazil, and from deserts of the south-western United States, Australia and the Kalahari of Africa. Methods We calcul...
متن کاملMicroclimate Conditions and Space Use Variations
This paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. The purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. We have employed a multi-method approach which combines a “qualit...
