Feeding ecology of North American gopher snakes (Pituophis catenifer, Colubridae)
TLDR
The feeding ecology of the North American gopher snake, Pituophis catenifer, was studied based on the stomach contents of more than 2600 preserved and free-ranging specimens, and published and unpublished dietary records to assess size-dependent and geographical variation in feeding preferences of gape-limited predators.
Feeding ecology of the Great Basin Rattlesnake (Crotalus lutosus, Viperidae)
TLDR
Great Basin Rattlesnakes also displayed geographic variation in feeding habits, with snakes from the Great Basin Desert eating a higher proportion of lizards than serpents from the more northern Columbia Plateau.
Phylogeography of the California mountain kingsnake, Lampropeltis zonata (Colubridae)
TLDR
Examination of colour pattern variation in 321 living and preserved specimens indicated that the two main colour pattern characters used to define the subspecies of L. zonata are so variable that they cannot be reliably used to differentiate taxonomic units within this complex, which calls into question the recognition of seven geographical races of this snake.
Gape size and evolution of diet in snakes: feeding ecology of erycine boas
TLDR
The stomach contents of museum specimens and specific literature records are used to describe the food habits of a basal clade of macrostomatan snakes ‐ the erycine boas (Erycinae) with an emphasis on the North American Charina bottae.
Molecular systematics of new world gopher, bull, and pinesnakes (Pituophis: Colubridae), a transcontinental species complex.
TLDR
It is believed that three distinct species are included in the melanoleucus complex, Pituophis melanoleUCus (sensu stricto), P. catenifer, and P. ruthveni, and that their recognition better represents the evolutionary diversity within this species complex.
EFFECTS OF DISPLAY SIZE, FLOWERING PHENOLOGY, AND NECTAR AVAILABILITY ON EFFECTIVE VISITATION FREQUENCY IN COMPARETTIA FALCATA (ORCHIDACEAE)
Mitochondrial DNA-Based phylogeography of North American rubber boas, Charina bottae (Serpentes: Boidae).
We used 783 bp of mitochondrial DNA sequences to study the phylogeography of Charina bottae (rubber boa) in western North America, with an emphasis on populations from California (U.S.A.).…
Multilocus phylogeographic assessment of the California Mountain Kingsnake (Lampropeltis zonata) suggests alternative patterns of diversification for the California Floristic Province
TLDR
The increased sampling of loci for L. zonata, combined with previously published multilocus analyses of other sympatric species, suggests that previous conclusions reached by comparative phylogeographic studies conducted within the California Floristic Province should be reassessed.
Molecular systematics of New World lampropeltinine snakes (Colubridae): implications for biogeography and evolution of food habits
TLDR
The reconstruction of the evolution of food habits among lampropeltinines suggests that a diet emphasizing lizards is ancestral, and therefore diets that mostly consist of mammals, squamate and bird eggs, and snakes are derived within the clade.
Signalling displays during predator–prey interactions in a Puerto Rican anole, Anolis cristatellus
TLDR
It is suggested that predation pressure may have reinforced the effects of sexual selection in the evolution of Anolis signalling displays because the predator deterrent signals are the same as the signals used in social interactions.
