Intraspecific variation in the energetics of the Cabrera vole.

摘要: Basal metabolic rate (BMR) is an intensively topic studied in ecophysiology for the purpose of understanding energy budgets species, variations expenditure during their diary activities and physiological acclimatization to environment. Establishing how metabolism assembled environment can provide valuable data improve conservation strategies endangered species. In this sense, differences associated habitats have been widely reported interspecific level, however little known about intraspecific view BMR under environmental gradient. study, we researched effect habitat on Iberian endemic species: Iberomys cabrerae. Animals were captured different subpopulations its altitudinal range MR was over a thermal analyzed through Linear Mixed Model (LMM) which, addition effects, bioclimatic zone sex also influenced The beginning thermoneutrality set 26.5°C RMR 2.3ml O2g(-1)h(-1), intermediate between both zones. Supramediterranean started Tlc earlier (24.9°C) had higher than mesomediterranean ones (26.9°C). together with primary productivity conditions could explain difference behaviour Cabrera voles.
