Waybright & Dillon combine new data on physiology with continental scale ground temperature data to develop landscapes of mortality risk for overwintering ectotherms, and apply the approach to predict mortality risk for overwintering bumble bee queens.

maps - Elevational (m) distributions for all squamate species climate niche compared between the recent (1981–2010) and late-century future RCP 8.5 climate scenarios (2070–2100) within each state. The 25th and 75th percentiles were compared to evaluate significance. Scenarios that do not overlap between the 25th and 75th percentiles were considered significantly different. (a) The count of species in each state where the distribution of elevation significantly increased. (b) The average median change between scenarios for each species that increased in elevation. (c) The count of species in each state where the distribution of elevation significantly decreased. (d) The average median change between scenarios for each species that decreased in elevation.

maps - Binary climate-niche rasters were combined across all species to create overall species richness and its geographic change between climate scenarios. Climate-niche species-richness map for (a) the recent climate scenario (1981–2010) and (b) late-century future RCP 8.5 climate scenario (2070–2100). Climate-niche species-richness change between the late-century future RCP 8.5 climate scenario (2070–2100) and the recent scenario (1981–2010) assuming (c) no dispersal ability for any species into novel areas, versus (d) full dispersal ability for any species into novel areas.

In their #JEB100 Commentary, @sammiefontaine & @KevinDKohl discuss how #microbiomes can influence the #thermaltolerance of #ectotherms, although questions remain regarding the role that microbes play in the thermal ecology & evolution of their hosts

Schematic diagram of a potential feedback loop between warming temperatures, microbial diversity and host heat tolerance. (1) Exposure to warming environments decreases host-associated microbial diversity in a variety of ectotherms. (2) Animals with disrupted microbiomes are often less tolerant to heat than those with undisrupted communities. (3) Animals that are less heat tolerant will be more vulnerable to increasing temperatures as climate change accelerates. These warming environments may further deplete microbial community diversity, beginning the cycle again. Created with Biorender.com.

I am ecophysiologist, with a focus on the effect of various environmental factors on the oxidative status of ectotherms. Special interest on amphibians and their ability to adapt to environmental changes, but I also examine the oxidative costs of interspecific hybridization.
