Feeding ecology of North American gopher snakes
Studies of food relations are important to our understanding of ecology at the individual, population and community levels. Detailed documentation of the diet of large-bodied, widespread snakes allows us to assess size-dependent and geographical variation in feeding preferences of gape-limited predators. Furthermore, with knowledge of the food habits of sympatric taxa we can explore possible ca...
متن کاملMolecular systematics of new world gopher, bull, and pinesnakes (Pituophis: Colubridae), a transcontinental species complex.
Pituophis melanoleucus (gopher, bull, and pinesnakes) is among the most widely distributed polytypic species complexes in North America, with most authors recognizing from a single transcontinental species (the melanoleucus complex, composed of 15 subspecies) to four (monotypic and polytypic) species. We used mitochondrial gene sequences from the two middle American species, P. deppei and P. li...
متن کاملFeeding Ecology of the California Mountain Kingsnake, Lampropeltis zonata (Colubridae)
Based on stomach contents of museum specimens and published records (n 5 51 prey items), Lampropeltis zonata eats lizards (37, 72.5%), squamate eggs (6, 11.8%), mammals (6), and birds (2, 3.9%). Juveniles feed on lizards, especially Sceloporus (spiny lizards) and Eumeces (skinks), whereas adults supplement their diet with squamate eggs and endothermic prey. Prey items are located by active fora...

متن کاملThe mechanics and muscular control of constriction in gopher snakes (Pituophis melanoleucus) and a king snake (Lampropeltis getula)
Constriction of prey by gopher snakes Pituophis melanoleucus and king snakes Lampropeltis getula is highly variable in posture, muscular activity and force exertion. These snakes typically use lateral bends of the anterior trunk to wind the body into a vertical coil around the prey. Three common constriction postures are fully encircling loops that form a coil, partially encircling loops, and n...
