Body size is manifestly one of the most important attributes of an organism from an
ecological and evolutionary point of view. Size has a predominant influence on an animal's …

Many species pass through several distinct age classes (instars or year classes) as they
grow. The variety of resources used by age classes effectively expands niche width. This" …

I examined the effects of age and body size on intra—and interspecific habitat relationships
for 15 species of fishes in a natural second—order warmwater stream. Juveniles (age 0) of …

The two conditions for stability of an evolutionary equilibrium, the m-stability and the δ-
stability conditions, are discussed. The m-stability condition is a condition for the …

Ecological causes for the evolution of sexual dimorphism can be confidently inferred only
when the sexes differ in morphology or relative size of the feeding apparatus, in a direction …

Body elongation and limblessness have evolved numerous times within Tetrapoda, typically
associated with aquatic, fossorial, crevice dwelling, or grassswimming lifestyles (Gans …

In size—structured populations interspecific competitors often have been suggested to have
their greatest impact on the juvenile life stage. We hypothesized that roach (Rutilus rutilus) …

This study examines the role of functional morphology of the feeding apparatus in
constraining the food habits of Caribbean wrasses (Labridae) in the genus Halichoeres. Like …

A 13‐year study of free‐ranging water pythons (Liasis fuscus) and their main prey (dusky
rats, Rattus colletti) in tropical Australia provided extensive data on the relationship between …

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 …
