With some notable exceptions, small ectothermic vertebrates are incapable of endogenously
sustaining a body temperature substantially above ambient temperature. This view was …

The reptilian form of hibernation (brumation) is much less studied than its mammalian and
insect equivalents. Hibernation and brumation share some basic features but may differ in …

Recent palaeoatmospheric models suggest large-scale fluctuations in ambient oxygen level
over the past 550 million years. To better understand how global hypoxia and hyperoxia …

The ectothermic vertebrates are a diverse group that includes the Fishes (Agnatha,
Chondrichthyes, and Osteichthyes), and the stem Tetrapods (Amphibians and Reptiles) …

The tegus increase in body mass after hatching until early autumn, when the energy intake
becomes gradually reduced. Resting rates of oxygen consumption in winter drop to 20% of …

The tegu lizard Salvator merianae is a large, widely distributed teiid lizard endemic to South
America that exhibits annual cycles of high activity during the spring and summer, and …

Tupinambis merianae, is a large, omnivorous tegu lizard native to South America. Two
populations of tegus are established in the state of Florida, USA, but impacts to native …

Ectotherm antipredator behaviour might be strongly affected both by body temperature and
size: when environmental temperatures do not favour maximal locomotor performance, large …

This study was designed to determine the manner in which metabolism is suppressed
during dormancy in black and white tegu lizards (Tupinambis merianae). To this end, heart …

Studies have suggested a role for natural seasonal change to drive patterns of disease,
especially within ectothermic vertebrates. In light of recent climate change, it is important to …
