Turtles are a small taxon that has nevertheless attracted much attention from biologists for centuries. However, a major portion of their life cycle has received relatively little attention untilExpand
Physiological Regulation and Conformation: A BASIC Program for the Determination of Critical Points
A BASIC program is given that fits two-segmented straight lines. It is applicable for analysis of data concerning the physiological response of an organism to varying environmental conditions whereExpand
ECOLOGY AND PHYSIOLOGY OF HIBERNATION AND OVERWINTERING AMONG FRESHWATER FISHES, TURTLES, AND SNAKES
1. Freshwater fishes are the most northerly of freshwater ectotherms, followed by frogs. North American freshwater snakes, turtles, and salamanders do not range farther north than southernmost Canada.
Metabolism, Critical Oxygen Tension, and Habitat Selection in Darters (Etheostoma)
Six species of darters (Etheostoma) were studied in the field and laboratory to relate respiration to habitat selection. The species ranged in habitat preference from a fast—water form (EtheostomaExpand
A re-evaluation of the relationship between temperature and the critical oxygen tension in freshwater fishes
Abstract o 1. The standard metabolic rate (SMR), and the critical oxygen tension ( P c ) were determined as a function of temperature for carp ( Cyprinus carpio ) and rainbow trout ( Salmo gairdneriExpand
Gas exchange, hypercarbia and acid-base balance, paleoecology, and the evolutionary transition from water-breathing to air-breathing among vertebrates
The evolutionary transition from water-breathing to air-breathing among vertebrates was accompanied by a shift in acid-base status from a low-PCO2, low [HCO3−] acid-base status to a high-PCO2,Expand
Long-Term Submergence at 3°C of the Turtle, Chrysemys Picta Bellii, in Normoxic And Severely Hypoxic Water: I. Survival, Gas Exchange And Acid-Base Status
Survival and blood acid-base status were measured on freshwater turtles ( Chrysemys picta bellii Gray) that were submerged at 3 °C in either aerated (high O 2 ) or N 2 -equilibrated (low O 2 ) water.Expand
MOLECULAR SYSTEMATICS, PHYLOGEOGRAPHY, AND THE EFFECTS OF PLEISTOCENE GLACIATION IN THE PAINTED TURTLE (CHRYSEMYS PICTA) COMPLEX
Abstract.— The painted turtle, Chrysemys picta, is currently recognized as a continentally distributed polytypic species, ranging across North America from southern Canada to extreme northern Mexico.Expand
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 insideExpand
