Abstract Predicting the biodiversity impacts of global warming implies that we know where and with what magnitude these will be encountered. Amphibians are currently most threatened vertebrates, mainly due to habitat loss emerging infectious diseases. Global may further exacerbate their decline in near future, although impact might vary geographically. We predicted subtropical amphibians should relatively susceptible warming‐induced extinctions because upper critical thermal limits ( CT max...
Summary 1 . Current studies indicate that estimates of thermal tolerance limits in ectotherms depend on the experimental protocol used, with slower and presumably more ecologically relevant rates warming negatively affecting upper (CT max ). Recent empirical evidence also gives credence to earlier speculations suggesting heritability could drop heating rates. 2 Using published data from fruit fly Drosophila melanogaster , we show patterns can be explained if flies’ physical condition...
Abstract Aim The climate variability hypothesis ( CVH ) states that a positive relationship may exist between the breadth of thermal tolerance range and level climatic experienced by taxa with increasing latitude, especially in terrestrial ectotherms. Under , we expected to find correspondence both limits CT max min), ambient extreme temperature sizes species. We examined validity these predictions lowland tropical temperate tadpole assemblage.

Abstract Anurans breed in a variety of aquatic habitats with contrasting levels desiccation risk, which may result selection for faster development during larval stages. Previous studies suggest that species ephemeral ponds reduce their developmental times to minimize risks, although it is not clear how variation risk affects strategies different species. Employing comparative phylogenetic approach including data from published and unpublished encompassing 62 observations across 30 species,...
Parsley frogs (Pelodytes) comprise the only genus in family Pelodytidae, an ancient anuran lineage that split from their closest relatives over 140 million years ago. Pelodytes is a Palearctic group restricted to Western Eurasia including three extant species: eastern species P. caucasicus, endemic Caucasus area, and two closely related inhabiting Europe: Iberian ibericus more widespread punctatus. Previous studies based on mitochondrial nuclear DNA markers have revealed existence of...
The "climate extremes hypothesis" is a major assumption of geographic studies heat tolerance and climatic vulnerability. However, this remains vastly untested across taxa, multiple factors may contribute to uncoupling limits. Our dataset includes 1000 entries data maximum temperatures for each species' known limits (hereafter, Tmax). We gathered information animal including marine fish, terrestrial arthropods, amphibians, non-avian reptiles, birds, mammals. first tested if constrains the...
Water salinity is an intense physiological stress for amphibians. However, some species, such as Bufo calamita, breed in both brackish and freshwater environments. Because selection under environmentally stressful conditions can promote local adaptation of populations, we examined the existence geographic variation water tolerance among B. calamita populations from either fresh or ponds Southern Spain. Comparisons were made throughout various ontogenetic stages. A combination field...

Abstract Aim Under the H utchinsonian concept of realized niche, biotic interactions and dispersal limitation may prevent species from fully occupying areas that they could tolerate physiologically. This can hamper translation physiological limits into climatically defined range distorts inferences evolutionary changes adaptive (i.e. niche conservatism). In contrast, heritable should conform more closely to position in climatic hyperspace. Here, we hypothesize a measure hyperspace is...
Although temperature variation is known to cause large-scale adaptive divergence, its potential role as a selective factor over microgeographic scales less well-understood. Here, we investigated how in breeding pond affects divergence multiple physiological (thermal performance curve and critical thermal maximum [CTmax]) life-history developmental reaction norms) traits network of Rana arvalis populations. The results supported responses face two main constraints limiting the evolution...
Abstract Aim We analysed elevational and microclimatic drivers of thermal tolerance diversity in a tropical mountain frog clade to test three macrophysiological predictions: less spatial variation upper than lower limits (Bretts’ heat‐invariant hypothesis); narrower ranges habitats with temperature (Janzen's climatic variability higher level heat impacts at elevations.

Abstract The vulnerability of species to climate change is jointly influenced by geographic phenotypic variation, acclimation and behavioural thermoregulation. importance interactions between these factors, however, remains poorly understood. We demonstrate how advances in mechanistic niche modelling can be used integrate assess the influence sources uncertainty forecasts impacts. explored variation thermal tolerance (i.e. maximum minimum limits) its potential for juvenile European common...

Water salinity represents an environmental stress for many species. Amphibians are particularly sensitive because they generally poor osmoregulators, and most species completely absent from brackish saline environments. We experimentally examined the effect of different levels on larvae toad Bufo calamita L., a that occupies freshwater ponds but can also breed in ponds. Two independent experiments reported here. In both experiments, tadpoles under conditions (ranging between 85 200 mOsm)...
To forecast biological responses to changing environments, we need understand how a species's physiology varies through space and time assess changes in physiological function due environmental may interact with phenotypic caused by other types of variation. Amphibian larvae are well known for expressing environmentally induced phenotypes, but relatively little is about these might temperatures their thermal physiology. address this question, studied the grey treefrog tadpoles (Hyla...
The climate variability hypothesis posits that increased environmental thermal variation should select for generalists, while stable environments favor specialists. This has been tested on large spatial scales, such as latitude and elevation, but less so smaller scales reflective of the experienced microclimate. Here, we estimated tolerance limits 75 species amphibian tadpoles from an aseasonal tropical mountain range Ecuadorian Andes, distributed along a 3500 m elevational range, to test...

Climate change may have dramatic consequences for communities through both direct effects of peak temperatures upon individual species and interspecific mismatches in thermal sensitivities interacting organisms which mediate changes interactions (i.e. predation). Despite this, there is a paucity information on the patterns spatial physiological sensitivity (at landscape local scales) could ultimately influence geographical variation climate community processes. In order to assess where these...
