Janzen's hypothesis (JH) posits that low thermal variation selects for narrow physiological tolerances, and thus small species distributional ranges high turnover along tropical elevational gradients. Although this has been intensely revisited, it does not explain how many may exhibit broad distributions, encompassing altitudinal Moreover, the responses of remain largely unknown, limiting our understanding on they respond to climate variation. To fill these knowledge gaps, we tested a major...
Amphibians are among the most threatened vertebrates in world and this is also true for those inhabiting Atlantic Forest hotspot, living ecosystems that highly degraded by anthropogenic activities. We present a data set containing information about amphibian communities sampled throughout Biome South America. The were extracted from 389 bibliographic references (articles, books, theses, dissertations) representing inventories of 1940 to 2017. includes 17,619 records 528 species with...
Human impacts on ecosystems have intensified water variability for terrestrial life, thus challenging the maintenance of balance, or hydroregulation. The accelerated development and accessibility technologies computational models over past decade enabled researchers to predict changes in animal hydroregulation environmental with greater spatial temporal precision. Focusing reptiles amphibians, we discuss current methods, limitations advances quantifying ecologically relevant metrics...
Geographical gradients of body size express climate-driven constraints on animals, but whether they exist and what causes them in ectotherms remains contentious. For amphibians, the water conservation hypothesis posits that larger bodies reduce evaporative loss (EWL) along dehydrating gradients. To address this mechanistically, we build well-established biophysical equations exchange anurans to propose a state-transition model predicts an increase either or resistance EWL as alternative...
Several amphibian lineages epitomize the faunal biodiversity crises, with numerous reports of population declines and extinctions worldwide. Predicting how such will cope environmental changes is an urgent challenge for biologists. A promising framework this involves mechanistic modeling, which integrates organismal ecophysiological features ecological models as a means to establish causal consequential relationships species their physical environment. Solid frameworks built other tetrapods...
The herpetofauna of São Paulo State, Brazil, can be characterized as the most well-known in country. However, despite large number studies this area, there are still many sampling gaps within biomes such Atlantic Forest that considered global conservation priorities due to high rate endemism and human disturbance. As a result political historical pressure, biome has been reduced less than 12% its original extent and, importance for biodiversity conservation, only small percentage vegetation...
The toad, Rhinella schneideri, is a large-bodied anuran amphibian with broad distribution over South America. R. schneideri known to be active at night during the warm/rainy months and goes into estivation dry/cold months; however, there no data on range of body temperatures (Tb) experienced by this toad in field, how environmental factors, thermoregulatory behaviors or activity influence them. By using implantable temperature dataloggers, we provide an examination Tb variation entire year...
Species exposed to prolonged drying are at risk of population declines or extinctions. A key missing element for assessments climate change is the sensitivity species water loss and their microhabitat preference, ecotype, as both dictate environmental drying. Here, we identified globally where water-sensitive ectotherms, i.e. anurans, increasing aridity drought, examined which ecotypes more sensitive from 238 species, estimated how behavioural activity impacted by future drought warming...
Respirometry is an important tool for understanding whole-animal energy and water balance in relation to the environment. Consequently, growing number of studies using respirometry over last decade warrants reliable reporting data sharing effective dissemination research synthesis. We provide a checklist guideline on five key sections facilitate transparency, reproducibility, replicability studies: 1) materials, set up, plumbing, 2) subject conditions/maintenance, 3) measurement conditions,...
It is broadly accepted that snakes are able to regulate their body temperature (Tb) behaviorally, but fundamental differences in this ability have been suggested exist between temperate and tropical species. Herein, we examined the thermal ecology of Golden Lancehead, Bothrops insularis, a critically endangered Neotropical crotaline snake endemic Queimada Grande Island (QGI), southeastern Brazil. We sampled Tb's individual found field tested which proximal factors, biotic abiotic, were...
Because of their permeable skin, terrestrial amphibians are constantly challenged by the potential risk dehydration. However, some physiological consequences associated with dehydration may affect aspects that themselves relevant to regulation water balance. Accordingly, we examined effects graded levels on rates evaporative loss and absorption through skin in Neotropical toad, Rhinella schneideri. Concomitantly, monitored mass visceral organs; hematocrit hemoglobin content; plasma...
ABSTRACT Total resistance (rt) to evaporative water loss (EWL) in amphibians is given by the sum of boundary layer (rb) and skin (rs). Thus, rs can be determined if rb component defined (rs=rt−rb). The use agar models has become standard technique estimate under assumption that surface imposes no barrier evaporation (rs=0). We evaluated this determining EWL rates values from exposed surfaces free water, a physiological solution mimicking osmotic properties generalized amphibian, gels...
Temperature affects physiological performance in reptiles and, therefore, body temperature (Tb) control is argued to have an important adaptive value. Alterations Tb due transient changes state, as during digestion or gestation, are often linked the potential benefits of a more precise regulation. However, such thermoregulatory responses nature remain controversial, particularly for tropical snakes. Herein, we measured golden lanceheads, Bothrops insularis (Amaral, 1921), at Queimada Grande...
Combining different sampling methods is essential to determine species richness. Recently, herpetological surveys have been conducted in poorly sampled regions Brazil using data from scientific collections as complementary information for richness estimated fieldwork. However, few studies evaluated discrepancies between estimation of obtained fieldwork and collections. Here, we demonstrate quantitatively how available can be important sources assessing amphibian reptile We used rarefaction...
