Species in the suborder Serpentes present a powerful model for understanding processes
involved in visual signal design. Although vision is generally poor in snakes, they are often …

Differences in snake color pattern have been demonstrated to affect behaviors involved in
antipredator defense. Snakes with blotched or banded color patterns are concealed when …

Each species of the snake fauna of North America north of Mexico was qualitatively scored
into one of five dorsal pattern classes and according to 16 behavioral-ecological variables …

Local populations of the adder, Vipera berus, are polymorphic for dorsal colour pattern,
containing both melanistic (black) and zig‐zag patterned individuals. Colour patterns in …

In an effort to clarify the evolutionary processes influencing color‐pattern variation in Lake
Erie island water snake (Nerodia sipedon) populations, rates of gene flow among island and …

A classic example of natural selection, that of color‐pattern variation in Lake Erie island
populations of water snakes, was reexamined to overcome shortcomings resulting from …

Color polymorphism in natural populations presents an ideal opportunity to study the
evolutionary drivers of phenotypic diversity. Systems with striking spatial, temporal, and …

Abstract Models of snakes varying in color pattern have been used to test hypotheses about
predation and mimicry. In the present study, clay models of the common garter snake were …

Correlational selection favors combinations of traits and is a key element of many models of
phenotypic and genetic evolution. Multiple regression techniques for measuring selection …

Multiple studies have addressed the mechanisms maintaining polymorphism within a
population. However, several examples exist where species inhabiting diverse habitats …
