The observation of heterothermy in a single suborder (Strepsirrhini) only within the primates is puzzling. Given that the placental-mammal ancestor was likely a heterotherm, we explored the potential for heterothermy in a primate closely related to t

Tropical ectotherms are generally believed to be more vulnerable to global heating than temperate species. Currently, however, we have insufficient knowledge of the thermoregulatory physiology of equatorial tropical mammals, particularly of small diu

Archaic mammals became exclusively nocturnal by the Late Triassic, and today, the majority of extant mammals remain nocturnal. Although there is ample morphological and physiological evidence supporting Late Mesozoic nocturnalism, a succinct hypothes

Recent palaeontological data and novel physiological hypotheses now allow a timescaled reconstruction of the evolution of endothermy in birds and mammals. A three-phase iterative model describing how endothermy evolved from Permian ectothermic ancest

This study provides first insights into the energetics of the Nesomyinae, a subfamily of rodents endemic to Madagascar. The ancestral nesomyine colonized Madagascar from Africa ca. 30–15 mya at the onset of Oligocene global cooling. We tested the h

Tenrecs (Order Afrosoricida) exhibit some of the lowest body temperatures (T b) of any eutherian mammal. They also have a high level of variability in both active and resting T bs and, at least in cool temperatures in captivity, frequently employ bot

The spiny tenrecs, an endemic subfamily of Malagasy insectivores (Tenrecinae), are wide ranging and fairly conspicuous, yet long-term studies on free-ranging populations remain sparse. Basal to most eutherian mammals, they share many ecological and m

Information on the spatial distribution and habitat use of the Tenrecidae (Supraorder: Afrotheria) of Madagascar are severely lacking. Here, we present the first data available on home range size, as well as further data on population distribution an
