Dates of emergence from hibernation, and the estimated ambient subsurface temperatures in the hibernacula, were used to investigate the effects of those temperatures on the emergence from hibernation of the box turtles, Terrapene carolina triunguis and T. o. ornata. In the spring, near St. Louis, Missouri, box turtles move from their hibernacula toward the surface of the ground as they follow a minimum ambient temperature of ca. 7 C. They emerge after 5 consecutive days of subsurface (10-20 cm… 
Seasonal Inactivity of the Desert Box Turtle, Terrapene ornata luteola, at the Species' Southwestern Range Limit in Arizona
Abstract At its southwestern range limit in southeastern Arizona, the Desert Box Turtle Terrapene ornata luteola, takes refuge in subterranean mammal burrows, primarily those of the Kangaroo Rat
Spring emergence of Eastern Box Turtles (Terrapene carolina): influences of individual variation and scale of temperature correlates
It is suggested that individual variation in emergence timing is common within populations and confounds efforts to identify reliable emergence cues, and the scale of meteorological data limits the ability to identify emergence predictors.
Thermal Environment of Overwintering Ornate Box Turtles, Terrapene ornata ornata, in Iowa
It is suggested that spring emergence may be correlated with a more complex set of factors and that Terrapene ornata ornata can withstand prolonged freezing temperatures.
Seasonal Thermal Ecology of Bog Turtles (Glyptemys muhlenbergii) in Southwestern Virginia
Temperature data loggers were deployed in wetlands occupied by Bog Turtles in southwestern Virginia to contrast the temperatures of the wetland environment to turtle carapace temperatures over two field seasons to evaluate probable hibernation depth and the timing and cues of spring emergence.
Hibernal Phenology of the Eastern Box Turtle, Terrapene carolina carolina
The eastern box turtle, Terrapene carolina carolina, is a terrestrial ectotherm that is vulnerable due to sustained population declines across its range in the Eastern United States. Where this
Hibernal thermal ecology of eastern box turtles within a managed forest landscape
Box turtles are being extirpated from much of their former range and remaining populations often live in association with anthropogenically altered habitats. This is particularly evident at the
Physiological ecology of overwintering in hatchling turtles.
Field biologists have long been intrigued by the environmental conditions survived by hatchlings using terrestrial hibernacula, especially nests that ultimately serve as winter refugia, and differential tolerances to these stressors may explain variation in hatchling overwintering habits among turtle taxa.
Minimal overwintering temperatures of red-sided garter snakes (Thamnophis sirtalis parietalis): a possible cue for emergence?
The hypothesis that an increase in ground temperature (and hence body temperature) is necessary for emergence from winter dormancy is not supported and it is suggested that critically low tempera- tures are a Zeitgeber entraining an endogenous circannual cycle that regulates snake emergence.
Patterns of variation in spring emergence by black rat snakes (Elaphe obsoleta obsoleta)
Patterns of spring emergence by black rat snakes observed at 13 communal hibernacula in eastern Ontario from 1992-1997 are reported and individuals demonstrated significant repeatability between years in their time of emergence relative to other snakes in the same bibernaculum.
Thermal environment and microhabitat of ornate box turtle hibernacula
This study suggests the phenology of box turtle hibernation may be similar across years and that hibernacula selection is driven by above- and belowground characteristics that ultimately lead to a more stable and warmer thermal environment.


Hibernation, Hibernacula and Associated Behavior of the Three-Toed Box Turtle (Terrapene carolina triunguis)
The following study was made on the Oliver Wildlife Preserve of the University of Oklahoma, 2 miles south of Norman, Cleveland County, Oklahoma, which consisted of approximately 60 acres, of which 50 acres were flood plain forest of the South Canadian River.
During 196 8 , a quantitative and descriptive field study was made in a 23 acre woodland on a population of the eastern box turtle, finding smaller turtles were found to be more active in the fall and individual turtles generally had a peak in weight in the latter part of the summer.
Overwintering Activity of Box Turtles (Terrapene carolina) in South Carolina
The study of the energy metabolism of dormant spadefoot toad Scaphiopus hammondi and the physiological correlates of forced activity and burrowing showed links to vitellogenesis, which led to the development of paedogenic Ambystoma tigrinum during viteLLogenesis.
Amphibians and Reptiles in Kansas
This edition of "Amphibians and Reptiles in Kansas" includes, for the first time, 96 colour photographs of salamanders, frogs and toads, turtles, lizards and snakes, as well as a collection of black-and-white photographs.
Introduction to the Study of the Reptiles of Indiana
The reptile group has become an increasingly popular one for students of natural history, and it is hoped that the descriptions and observations assembled from the literature may be useful to amateur naturalists and in the schools.
We Need Both Exploratory and Confirmatory
This work states that exploratory data analysis is an attitude, a flexibility, and a reliance on display, NOT a bundle of techniques, and should be so taught, and confirmatory analysis is easier to teach and easier to computerize.
