ABSTRACT The development of in situ applicable mitigation methods against diseases is an area conservation biology that deserves more attention. chytrid fungus Batrachochytrium dendrobatidis (Bd) causes chytridiomycosis, infectious disease amphibians. Although it responsible for population declines and extinctions worldwide, no widely method available the disease. has a lower thermal tolerance than most amphibian species, which raises possibility curing individuals with treatments, alternative likely safer to use under natural conditions chemicals. Amphibians, being ectothermic animals, actively seek warm environments, so presenting them reaching their preferred body temperatures may be mild but effective intervention. In this study, we tested whether providing heated shelter Bd‐exposed common toad ( Bufo bufo ) tadpoles, kept seminatural at different densities, helps eliminate infection or reduce its costs. We found tadpoles access shelters decreased intensity not prevalence Bd‐infection, density did alter beneficial effect treatment. mean mass was lowered when were high density, availability have on individuals. Our results suggest application microrefugia help Bd‐infected overcome disease, device itself both need further improvements. could become cheap treatment chytridiomycosis other waterborne, cold‐adapted pathogens nature conservation.

ABSTRACT Ectothermic vertebrates with genotypic sex determination may adjust their sexual phenotype to early‐life environmental conditions by reversal, and theoretical models predict diverse consequences for population dynamics microevolution under change. Environments that frequently expose individuals sex‐reversing effects select or against the propensity undergo depending on relative fitness of sex‐reversed individuals. Yet, empirical data adaptive value evolutionary potential reversal is scarce. Here we conducted a common‐garden experiment agile frogs ( Rana dalmatina ) respond larval heat stress test whether sex‐reversal has changed via in populations live anthropogenic habitats where potentially events are more frequent, compared cooler woodland habitats. Furthermore, infer fitness‐related traits between heat‐exposed females phenotypically developed into males (sex‐reversed) (sex‐concordant). We found frequency varied sibgroups was higher originating from habitats, regardless thermal environment they had been exposed during sex‐determination period. Among animals, time metamorphosis similar sex‐concordant females, but former reached larger body mass end than latter, approaching males. These results suggest have increased environments microevolution, minimize cost reduced growth caused events. Thus, provide an strategy ectothermic cope challenges Anthropocene. Such knowledge causes will help pinpoint which most threatened extinction due climatically influenced determination.

Abstract Urban phenotypic divergences are documented across diverse taxa and commonly assumed to result from microevolution, but the underlying genetic environmental drivers behind these changes unknown in most wild urban systems.

In line divergence wild, had faster breath rates (i.e., higher stress response) were smaller than origins, suggesting differentiation has driven differences. Conversely, differences aggression exploration not garden, indicating plasticity conditions likely drives shifts.

Among-individual size response similar contexts, whereas among-individual lower wild.

Synopsis Intraspecific variation can be as great across species, but the role of intraspecific in driving local and large-scale patterns is often overlooked, particularly field thermal biology. In amphibians, which depend on environmental conditions behavior to regulate body temperature, recognizing trait essential comprehensively understanding how global change impacts populations. Here, we examine drivers micro- macrogeographical amphibians. At scale, arise via changes ontogeny, size, between sexes, developmental plasticity, acclimation, maternal effects may modulate predictions amphibian performance under future climate scenarios. macrogeographic adaptation traits occur along latitudinal elevational gradients, with seasonality range-edge dynamics likely playing important roles that impact persistence. We also discuss importance considering disease a factor affecting population resilience change, given pathogens preferences critical limits hosts. Finally, make recommendations for work this area. Ultimately, our goal demonstrate why it researchers consider determine amphibians change.
