Geographic variation in thermal physiological performance of the intertidal crab Petrolisthes violaceus along a latitudinal gradient
(2014)
Environmental temperature has profound effects on the biological performance and biogeographical distribution of ectothermic species. Variation of this abiotic factor across geographic gradients is expected to produce ...
Geographic Variation in the Acoustic Signals of Dendropsophus nanus (Boulenger 1889) (Anura: Hylidae)
(2020-09-09)
Anurans communicate information during breeding activity to conspecifics mainly through acoustic signals, and different evolutionary forces may produce geographic variation in such communication systems. To understand which ...
