The relationship between population dynamics and dietary preferences within two snake genera (Storeria and Thamnophis)
… between <em>Storeria dekayi</em> and <em>Thamnophis sirtalis</em> and their less abundant and more geographically restricted sister species, <em>Storeria occipitomaculata</em> and <em>Thamnophis butleri</em>, in Illinois and Michigan. I hypothesized that greater abundance and more …

Impacts of the invasive Brook Stickleback (Culaea inconstans) on wandering garter snake (Thamnophis elegans vagrans) fitness, feeding behavior and diet
<p>There are multiple examples of Natricine snakes not only changing their diet to utilize an invasive fish, but deriving a fitness benefit from the new and often abundant prey item as well. To investigate a potentially similar scenario arising on the Turnbull National Wildlife Refuge (Spokane Co., …

Habitat Use And Seasonal Activity Of Selected Snakes On John F. Kenned
… commonly captured species, Coluber constrictor, Thamnophis sirtalis, and Thamnophis sauritus, combined made up 85% of the sample. These three species were active during every month of the year, but showed modal activity patterns typical of Temperate Zone snakes. Monthly snake captures were …

Phenotypic consequences of adaptive toxin production and resistance in coevolutionary partners
… Amazingly, multiple species of garter snakes (Thamnophis) have adapted to overcome this defense, harboring mutations that prevent TTX from binding to its target. These mutations, however, also decrease protein and muscle function, which suggests garter snakes may suffer evolutionary tradeoffs. …

Nest predation and habitat selection in the grasshopper sparrow (Ammodramus savannarum)
… season. Burning reduced losses by snakes (Thamnophis and Coluber spp.), whereas predation by mammals and snakes increased with litter cover and fescue (Schedonorus phoenix) surrounding the nest. Mammals were less likely to prey upon nests with increased forb cover as well. Nest losses …

Chemically-mediated prey responses: invasive brook stickleback induced changes in behavior and life history of larval long-toed salamanders
… chemical cues (kairomones) from garter snakes (Thamnophis elegans), tiger salamanders (A. tigrinum) and brook stickleback (Culaea inconstans), which had been fed a larvae-diet of A. macrodactylum or a null-diet of earthworms (Lumbricus terrestris), and measured subsequent changes in A. …

The Influence of Tail Autotomy on Avoidance of Chemical Alarm Cues in Northern Zigzag Salamanders, Plethodon dorsalis
… macerations) and those of eastern garter snakes, Thamnophis sirtalis. Tail autotomy combined with the time since tail autotomy did not influence predator avoidance of P. dorsalis to chemical alarm cues of injured conspecifics or those of T. sirtalis. Also, P. dorsalis did not avoid chemical cues …
