Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 857-867, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...
