• Abstract

  As ectotherms, anuran amphibians face constant challenges to meet requirements of thermoregulation in the kinds of heterogeneous environments they occupy. This is true especially when a frog becomes sick and the response of behavioral fever triggers more directed habitat choice. These frogs encounter microhabitats and arrays of complex environmental microbiomes that can facilitate behavio…

• Abstract

  An unequivocal pattern that involves both natural and anthropic causes, is the global, yet heterogeneous, change in the climate of Earth. This trend, paralleled by other anthropic environmental changes, is expected to cause pervasive effects on the fauna. However, the nature, span and final consequences of climate change must differ among taxa, even among related species, because of the v…

• Abstract

  The vulnerability of organisms to environmental change must be based on biologically relevant information at different levels of organization, including physiological and behavioral aspects. In the context of ectothermic vertebrates, the first historical approach aimed to obtain "performance curves" relating the speed of lizards with body temperature. These curves contain information abou…

• Abstract

  The SPEC Innovations in Human and Non-Human Animal Communities project aims to reconstruct the evolutionary history of three allegedly human-specific cognitive abilities, namely: linguistic competence, symbolic activities, and sophisticated tools.One topic within this broad question refers to the antecedents, if any, that exist in non-human animal species. Whereas primates and birds have …

• Abstract

  Climate change is causing large modifications in distribution and population structures of living organisms due to the influence of temperature on its bodily functions (e.g. increase in global temperature or its wider and more frequent oscillations). To understand, predict and mitigate such influence, we need investigations on the effects of temperature on the homeostatic regulation of ph…

• Abstract

  The interplay between ecology and behavior is important when discussing how and why environmental change affects patterns of distribution and other elements of ecology during the Anthropocene. Physiological ecology is at the core of this interplay, with a disciplinary focus on the relationship between individuals and environment, as defined by physiology. Experimental work matters in phys…

• Abstract

  Anurans display different types of locomotion that are related to their ecology and habitat use. Locomotion is generally regarded as a crucial activity for survival and as an important component of the energy budget. Given its high energetic cost, locomotion can be compromised by other physiological processes. One example is the response to an infection (i.e. an immune response). Conseque…

• Abstract

  Although in nature organisms face thermal fluctuations in time and space that integratively influence their physiology and behavior, experimental studies have focused mainly in the temporal component of thermal landscapes and neglected the spatial one. In fact, the literature presents contrasting evidence between adaptive patterns found in laboratory vs. natural conditions, probably becau…
