Abstract Climate change is putting the fate of ectothermic animals at stake because their body temperature closely tracks environmental temperatures. The ability to adjust thermal limits and preference through acclimation (i.e. capacity) may compensate for changes.

Abstract The ecological niche can be thought of as a volume in multidimensional space, where each dimension describes an abiotic condition or biotic resource required by species. shape, size, and evolution this strongly determine interactions among species influence their current potential geographical distributions, but the geometry niches is poorly understood. Here, we analyse temperature response functions host plant ranges for hundreds potentially destructive plant-associated fungi oomycetes. We demonstrate that specialization uncorrelated on (i.e. response) range) axes, restrict fundamental breadth to form realized niche, both show limited phylogenetic constraint. terms ‘generalist’ ‘specialist’ therefore do not apply these microbes, evolves independently different axes. This adaptability makes pathogens formidable threat agriculture forestry.

Reptiles are critically affected by temperature throughout their lifespan, but especially so during early development. Temperature induced changes in phenotype a specific example of broader phenomenon called phenotypic plasticity which single individual is able to develop different phenotypes when exposed environments. With climate change occurring at an unprecedented rate, it important study effects on reptiles. For example, the potential impact global warming pronounced species with temperature-dependent sex determination (TSD) because has direct effect key (sex) and demographic (population ratios) trait. TSD also serve as models for studying development other traits that display continuous variation. directly influences metabolic developmental rate embryos can have permanent last beyond embryonic period. instance, incubation programs post-hatching hormone production growth physiology, profoundly influence fitness. Here, we review current knowledge First, examine biophysical processes, concept thermal performance curves, process acclimation. After discussing these reversible effects, focus bulk programming embryogenesis (i.e., effects). We oviparous eggs susceptible ambient temperature. then discuss recent work probing role epigenetic mechanisms mediating phenotype. Based temperature, return Finally, highlight areas future research, including identification sensors assessment genetic variation thermosensitivity.
