Item Moisture loss in relation to habitat selection in some Floridian reptiles. American Museum novitates ; no. 1358(New York City : The American Museum of Natural History, 1947) Bogert, Charles M. (Charles Mitchill), 1908-1992.; Cowles, Raymond B. (Raymond Bridgman), 1896-1975.; Archbold Biological Station."Ten species of Floridian reptiles were subjected to nearly constant environmental temperatures of 38° C. in an experimental chamber in which the relative hunidity was maintained at a level approximating 37 per cent. An additional species, a subterrestrial lizard, was subjected to wet and dry sand at room temperatures. The experimental animals were weighed at periodic intervals during their exposure to such extreme environmental conditions, and those that survived were returned to a moist environment and weighed again. A few reptiles maintained in the thermal chamber in closed containers with wet sand in the bottom lost no weight so that it could be relatively certain that loss in weight represented a loss of moisture"--P. 33.Item A preliminary study of the thermal requirements of desert reptiles. Bulletin of the AMNH ; v. 83, article 5(New York : [American Museum of Natural History], 1944) Cowles, Raymond B. (Raymond Bridgman), 1896-1975.; Bogert, Charles M. (Charles Mitchill), 1908-1992.Item Temperature tolerances in the American alligator and their bearing on the habits, evolution, and extinction of the dinosaurs. Bulletin of the AMNH ; v. 86, article 7(New York : [American Museum of Natural History], 1946) Colbert, Edwin Harris, 1905-; Cowles, Raymond B. (Raymond Bridgman), 1896-1975.; Bogert, Charles M.
