Introduction, The scientific literature on foraging biology in lizards has tended to ignore
intraspecific variation. Thus, the species is treated as the unit of analysis, under the implicit …

Recent advances in ecological niche modeling (ENM) algorithms, in conjunction with
increasing availability of geographic information system (GIS) data, allow species' niches to …

Obtaining nourishment is one of the most essential activities engaged in by organisms, and
has therefore attracted much interest. Despite this, some of the most basic claims and …

One useful theoretical focus in evolutionary ecology that may advance us toward an
integrative understanding of the major features of adaptedness of any population or species …

The evolution of ecological and behavioral traits is difficult to study because of the absence
of such traits from the fossil record. For example, variation in lizard territoriality both within …

The role of interspecific competition as a key factor in the ecology of natural communities
where species exploit limited resources is well established, and the study of competition …

Sometimes a straightforward natural history observation initiates the development of a major
area of research in ecology or evolutionary biology. The observation that species numbers …

The existence of evolutionary trade-offs prevents simultaneous optimization of different
functions that require opposing biomechanical or physiological adaptations (Stearns, 1992) …

Although many descriptive studies of foraging mode have been performed, the factors that
underlie the evolution of foraging mode remain poorly understood. To test the hypothesis …

Sexual dimorphism in phenotypic traits associated with the use of resources is a widespread
phenomenon throughout the animal kingdom. While ecological dimorphisms are often …
