Estimating the influence of the thermal environment on activity patterns of the desert woodrat (Neotoma lepida) using temperature chronologies

Abstract: Environmental temperature influences the ecology and life history of animals. In habitats near the thermal range boundary, fluctuations in temperature may influence the ability of species to persist. Desert woodrats ( Neotoma lepida Thomas, 1893) occupy one of the hottest and most extreme environments in the western hemisphere, Death Valley, California, despite limited adaptations for water conservation or efficient heat dissipation. Moreover, N. lepida have a relatively low tolerance for high temperature. Thu… Show more

“…DISCUSSION In order to maintain their energy and nutritional balance, animals cope with variations in the trophic scenario through behavioural and physiological adjustments that translate into their dietary choices (Sherry 1990;Chambers et al 1995;Kyriazakis et al 1999;Sassi et al 2011). Furthermore, all this occurs under temperature and other climatic factors that impose diverse energy demands and restrictions to the foraging behaviour (Caraco et al 1990;Murray & Smith 2012).…”

“…When attached externally to an animal, the temperature recorded is often intermediate between body temperature and the ambient temperature of the environment immediately surrounding the individual (Osgodd & Weigl, 1972;Studd, Boutin, McAdam, & Humphries, 2016;Tremblay, Cherel, Oremus, Tveraa, & Chastel, 2003). Most pertinent here, collar temperature likely offers useful information about behavioral state, as it tends to more closely approximate the body temperature of inactive animals confined in small spaces (e.g., thermal refuges) and to more closely approximate the air temperature experienced by active animals fully exposed to ambient conditions (Körtner & Geiser, 2000;Messier, Taylor, & Ramsay, 1994;Murray & Smith, 2012;Olson et al, 2017;Wassmer & Refinetti, 2016). However, depending on the ecology of the species and which of these two temperatures vary more, collar temperature can be used to monitor thermal exposure (Osgodd & Weigl, 1972;Kanda, Fuller, & Friedland, 2009) or heterothermic fluctuations indicative of torpor expression or hibernation (Lazerte & Kramer, 2016).…”
