The onset of hibernation or estivation
in juvenile mammals is different from that in adults.
2001), between wetlands (Piepgras and Lang, 2000; Rowe and Moll, 1991), and is occasionally found in terrestrial habitats during bouts of estivation (Ross and Anderson, 1990; Joyal et al.
Several turtles endured multiple bouts of estivation in dry terrestrial or moist marsh beds during 2005; the longest period of inactivity averaged 18.
American spadefoot toads (Scaphiopus), for example, spend most of the year in estivation
up to 3 ft (1 m) below the soil surface.
Elongate amphibians such as salamanders and caecil-ians coil under many conditions including resting, brooding eggs, defense, and estivation
(Cochran, 1911; Heatwole, 1960; Brodie, 1977; Brodie et al.
sites include ponds or marshes (Ward et al.
The ambient and physiological conditions determining the start of estivation
are unclear, but C.
Sonoran mud turtles frequently move between aquatic and terrestrial habitats, including movements among pools and movements into terrestrial estivation
sites (van Loben Sels et al.
Regulation of glycolysis in the land snail Oreohelix during estivation
and artificial hypercapnia.
Skeletochronology can be used in animals that exhibit annual cycles of growth, typically associated with warmer or wetter periods, and torpor or estivation
associated with cooler or drier periods.
