Geographic variation in behaviors that influence resource utilization is a key component in current ecological theory, but the phenomenon has been poorly documented. Propensity to attack slugs varies geographically in a western garter snake, Thamnophis elegans. Many naive, newborn snakes from inland localities in California refuse to eat slugs. In contrast, virtually all naive young from coastal localities eat slugs. There is, however, no demonstrable polymorphism or geographic variation for… 
Garter Snake Diets in a Fluctuating Environment: A Seven-Year Study
TLDR
Snakes foraged more successfully, judging from the incidence of stomachs containing prey, in years when metamorphic toads (Bufo boreas) were available.
Microgeographic variation in the diets of garter snakes
TLDR
Diets of the terrestrial garter snake and the common garterSnake were studied at 22 sites in an area of about 250 km2 in northern California during the summers of 1978–80, where T. sirtalis consumed mostly amphibian and T. elegans ate an equal mixture of amphibians, fish, and leeches.
Variation in the Diet of the Mexican Black-bellied Gartersnake Thamnophis melanogaster: Importance of Prey Availability and Snake Body Size
TLDR
It is suggested that the observed interannual and seasonal variation observed in Mexican Black-bellied Snakes is due mostly to temporal variation in prey availability and proportions of snake size classes.
BEHAVIORAL VARIATION IN NATURAL POPULATIONS. II. THE INHERITANCE OF A FEEDING RESPONSE IN CROSSES BETWEEN GEOGRAPHIC RACES OF THE GARTER SNAKE, THAMNOPHIS ELEGANS
  • S. J. Arnold
  • Biology
    Evolution; international journal of organic evolution
  • 1981
TLDR
Despite its novel and unseemly aspects, this analysis of slug-eating in a garter snake apparently represents the most thorough documentation of geographic variation in behavior in the vertebrate literature.
Evolutionary interplay between ecology, morphology and reproductive behavior in threespine stickleback, Gasterosteus aculeatus
TLDR
The morphology of populations exhibiting both group cannibalism and a second kind of cannibalism in which solitary females court males, gain access to nests as a consequence, and then cannibalize eggs without spawning are compared.
The energetic consequences of dietary specialization in populations of the garter snake, Thamnophis elegans
TLDR
The hypothesis that snakes with specialized diets can evolve physiological traits to extract nutrients more efficiently is supported as there was no apparent trade-off on the more generalized diet that was associated with this specialization.
Global biogeographical patterns in the diet of a cosmopolitan avian predator
TLDR
Patterns of trophic ecology in a cosmopolitan nocturnal raptor, the common barn owl group, are described from a biogeographical perspective to compare variation in diet between barn owls living in the Americas, and those inhabiting Europe, Middle‐East and Africa.
Geographic variation in the foraging behavior of the garter snake, Thamnophis elegans
TLDR
According to behavioral comparisons, the coastal population of the garter snake Thamnophis elegans has retained all the elements of its aquatic foraging repertoire, but its tendencies to perform them have diminished.
Geographical ecology of Tantilla melanocephala (Squamata: Serpentes: Colubridae) in a Neotropical region: a comparison of northeastern Atlantic Forest and Caatinga populations
Studying species with wide geographical distributions allows the evaluation of the effects of environmental variation and phylogenetic constraints on the ecology of these organisms. The snake Tanti...
Strong response to anuran chemical cues by an extreme dietary specialist, the eastern hog-nosed snake (Heterodon platirhinos)
TLDR
These findings are consistent with those of several other investigators in showing close correspondence between the inclusion and importance of dietary items and the intensity of chemosensory investigation in snakes.

Snake Food Preference: Innate Intraspecific Geographic Variation
TLDR
Compared to Florida individuals, a smaller percentage of Massachusetts Thamnophis sirtalis sirtali will accept fish; the behavior is innate and correlated with habitat differences between the two localities.
Intraspecific Geographical Variation in Chemical Food Cue Preferences of Newborn Garter Snakes (Thamnophis Sir Talis)
TLDR
Geographic differences in responses to chemical cues within a species were shown as seen in the responses to the fish and earthworm extracts in garter snakes born to females captured in three different geographic areas.
CALL DIFFERENTIATION IN A COMPLEX OF SEVEN SPECIES OF CRINIA (ANURA, LEPTODACTYLIDAE)
TLDR
Seven species of the Australian leptodactylid genus Crinia Tschudi appear to have the characteristics desirable for a study of the origin of differences in male call, and this isolating mechanism among the members of a closely related species group may be of interest.
Revision of the Giant West Coast Land Slugs of the Genus Ariolimax Moerch (Pulmonata: Arionidae)
TLDR
A revision of the taxonomy of this genus is published with adequate information on its speciation, phylogeny, and distribution, and the morphological aspects are limited to those external and internal structures, which are or have been considered of taxonomic importance.
VARIATION AND EVOLUTION OF THE PUSH-UP DISPLAYS OF THE SIDE-BLOTCHED LIZARD GENUS UTA (IGUANIDAE)
TLDR
Variation in the displays can be divided into seven geographic zones of push-up similarity; taxonomic recognition of the display variation may require revision of the infraspecific taxonomy of Uta stansburiana.
Chemical prey preference polymorphism in newborn garter snakes Thamnophis sirtalis.
TLDR
Newborn, previously unfed garter snakes respond with prey attack and tongue flicking to water based extracts prepared from the surface substances of normally eaten prey and presented on cotton swabs, demonstrating reliable individual differences in preferred stimuli among members of the same litter.
Chemical-Cue Preferences of Newborn Snakes: Influence of Prenatal Maternal Experience
TLDR
The initial stimulus control of the attack response in newborn snakes seems relatively unmodifiable, in contrast with the easy modifiability of chemical-cue preferences in young snakes after birth.
