Sexual size dimorphism (SSD) is common in both plants and animals, and current evidence
suggests that it reflects the adaptation of males and females to their different reproductive …

Males and females of nearly all animals differ in their body size, a phenomenon called
sexual size dimorphism (SSD). The degree and direction of SSD vary considerably among …

Why do males and females frequently differ so markedly in body size and morphology? Sex,
Size, and Gender Roles is the first book to investigate the genetic, developmental, and …

Rensch's rule states that sexual size dimorphism (SSD) increases with body size
(hyperallometry) in taxa in which males are the larger sex and decreases with body size …

In comparative studies of sexual size dimorphism (SSD), the methods used to quantify
dimorphism are controversial. SSD is commonly expressed as a ratio between species …

Understanding the mechanics of adaptive evolution requires not only knowing the
quantitative genetic bases of the traits of interest but also obtaining accurate measures of the …

Bergmann's and Rensch's rules describe common large‐scale patterns of body size
variation, but their underlying causes remain elusive. Bergmann's rule states that organisms …

We manipulated, in accord with global—warming predictions, the thermal regime of a
permanent first—order stream near Toronto, Ontario, Canada. We examined the effects of a …

Sexual size dimorphism (SSD) is the evolutionary result of selection operating differently on
the body sizes of males and females. Anolis lizard species of the Greater Antilles have been …

Sexually antagonistic coevolution may be an important force in the evolution of sexual
dimorphism. We undertake a comparative study of correlated evolution of male and female …
