Previous studies of sexual size dimor-phism (SSD) use a variety of size dimorphism indices
(SDI's) to quantify SSD. We propose that a useful SDI should meet four criteria as follows; 1) …

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 …

It is generally recognized that larger animals eat more, live longer, have larger offspring, and
so on; but it is unusual to see these commonplace observations as a basis for scientific …

(Invited Article) Abstract Sexual size dimorphism (SSD) is widespread and variable among
animals. According to the differential equilibrium model, SSD in a given species is expected …

Sexual size dimorphism (SSD) in the slider turtle, Trachemys scripta, is pronounced; females
attain larger body sizes than males in all populations for which data are available. The …

A prominent interspecific pattern of sexual size dimorphism (SSD) is Rensch's rule,
according to which male body size is more variable or evolutionarily divergent than female …

Sexual size dimorphism (SSD) typically increases with body size (hyperallometry) in taxa in
which males are the larger sex and decreases with body size (hypoallometry) in taxa in …

Birds experience strikingly different patterns of mass change during breeding. In some
species with uniparental incubation, the incubating parents (mostly females) lose mass and …

Two factors complicate the analysis of scaling relationships between neonatal size or
gestation period and maternal size in mammals:(1) a fundamental distinction between …
