Aim Climate change is expected to impose severe physiological stress on ectotherms, potentially reshaping their geographic distributions. Many species are expected to be impacted by the detrimental effects of climate change on their homeostatic balance, with suitable habitat shifting to higher latitudes and elevations. However, little is known about the ecophysiological mechanisms driving their redistribution and the extent to...
A global analysis of field body temperatures of active squamates in relation to climate and behaviourNARA Subscribed
Aim Squamate fitness is affected by body temperature, which in turn is influenced by environmental temperatures and, in many species, by exposure to solar radiation. The biophysical drivers of body temperature have been widely studied, but we lack an integrative synthesis of actual body temperatures experienced in the field, and their relationships to environmental temperatures, across phylogeny, behaviour and climate. Locatio...
The biogeography of warming tolerance in lizardsNARA Subscribed
Aim Many ectotherms are at risk from climate change as temperatures are increasingly exceeding their thermal limits. Many evaluations of the vulnerability of ectotherms to climate change have relied on statistical metrics derived from coarse‐scale climatic data, which may result in misleading predictions. By applying an integrative approach, we investigated geographical correlates of the vulnerability of lizards to climate cha...
A database of the morphology, ecology and literature of the world's limb‐reduced skinksNARA Subscribed
Aim Limb‐reduced squamates are a convenient model system to investigate macroevolutionary trends in morphology. Here, we provide morphological, ecological and literature data on all known species of limb‐reduced skinks (Scincidae) and their relatives, representing one of the most diverse and widely distributed groups of limb‐reduced squamates. Location Global. Taxon Skinks (Reptilia, Squamata: Scincidae). Limb‐reduced forms. M...
Ecophysiology of a small ectotherm tracks environmental variation along an elevational clineNARA Subscribed
Aim Physiological responses to climate can be used to quantify the environmental limits that a species can tolerate and are, therefore, key to biogeographical studies. Several ecophysiological responses to climatic factors may shape the distribution of species, but our knowledge is mostly centred in thermal ecophysiology. We applied an integrative approach to investigate how ecophysiological responses of a small ectotherm are...
Aim Our understanding of species’ responses to climate depends on choosing the scale for the analysis. Processes driving physiological adaptation that occur at the small spatial scales most relevant to animals may be masked in correlations between organismal traits and broad‐scale climatologies, but the extent to which this undermines our understanding of the macroevolution of physiological traits is unknown. Location Global....
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyon...
