Incubation temperature has long-term effects on behaviour of young Pine snakes ( Pituophis melanoleucus )

摘要: Eggs of pine snakes (Pituophis melanoleucus) were incubated at constant temperatures 21°, 23°, 26°, 28°, 30° and 32° C to determine behavioural differences as a function incubation temperature. For all physiological measures hatchlings from medium (26°, 28°) performed tests better than those eggs low (21°, 23°). some high temperature (30°, 32°) less well hatchlings. These not due ambient or age testing since these held constant. Some the persisted for 24 weeks.
