Scale-eating in characoids and other fishes, they sink, or picked up from the bottom. Scale-eating is probably a size-limited habit. Specialized scale-eaters rarely exceed 200 mm, most ranging near 120 mm. Some species eat scales only when young; most take other food items in addition to scales. Scale-eating habits probably arose from trophic

The evolutionary ecology of respiratory mode in fishes: an analysis based on the costs of breathingredation pressure and several morphological and behavioral characteristics may also have an influence. These factors are integrated into a general theory of breathing costs which permits prediction of patterns in respiratory partitioning, habitat selection, the frequency of occurrence of respiratory

Evolutionary genetics of trophic differentiation in goodeid fishes of the genus ,,t the morphs are components of the same gene pool, i.e. they are conspecific. This hypothesis receives additional support from analysis of the broods of field-impregnated females..A chromosomal polymorphism, probably involving pericentric inversions, exists at one or more sites in the Río del Tule s

Natural and sexual selection on color patterns in poeciliid fishes,ip between predation intensity and color pattern is different for melanin, carotenoid, and structural colors. Different color patterns have different degrees of conspicuousness on different backgrounds, and may appear differently to predators and mates with differing visual abilities.

On measuring niches and not measuring them, the 6 measures, we recommend the overlap equation based on the Freeman-Tukey statistic, primarily because the variance estimates do not depend on the resource data set, but on the measure itself. Using our methods one can (a) compare a calculated overlap value with any specified value (e.g., does i
