Physiological ecology of overwintering in hatchling turtles.
Temperate species of turtles hatch from eggs in late summer. The hatchlings of some species leave their natal nest to hibernate elsewhere on land or under water, whereas others usually remain inside the nest until spring; thus, post-hatching behavior strongly influences the hibernation ecology and physiology of this age class. Little is known about the habitats of and environmental conditions a...
متن کاملPotential sources of intra-population variation in the overwintering strategy of painted turtle (Chrysemys picta) hatchlings.
Many temperate animals spend half their lives in a non-active, overwintering state, and multiple adaptations have evolved to enable winter survival. One notable vertebrate model is Chrysemys picta, whose hatchlings display dichotomous overwintering strategies: some hatchlings spend their first winter aquatically after nest emergence in the autumn, whereas others overwinter terrestrially within ...
متن کاملThe Overwintering Strategy of Hatchling Painted Turtles, or How to Survive in the Cold without Freezing
P turtles (Chrysemys picta) are common residents of shallow lakes and marshes across much of North America east of the Rocky Mountains—so common, in fact, that the species has become a “model organism” for studies on the ecology and evolution of chelonians (Wilbur and Morin 1988). The natural history of painted turtles differs from that of most other species in an important respect, however. Wh...
متن کاملBrief Chilling to Subzero Temperature Increases Cold Hardiness in the Hatchling Painted Turtle (Chrysemys picta).
Although many studies of ectothermic vertebrates have documented compensatory changes in cold hardiness associated with changes of season, much less attention has been paid to adjustment of physiological functions and survival limits following more acute exposure to cold. We investigated the ability of hatchling painted turtles (Chrysemys picta) to increase cold hardiness in response to brief e...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
