Male‐biased sexual size dimorphism (SSD) in mammals has been explained by sexual
selection favouring large, competitive males. However, new research has identified other …

In this cross-sectional study gender differences in body composition (relative fat mass and
lean body mass adjusted by height) were analyzed among 869 girls and 780 boys aging …

Background Body mass estimation is of paramount importance for paleobiological studies,
as body size influences numerous other biological parameters. In mammals, body mass has …

Food availability is likely to influence body condition and, in turn, fitness. The intensity of this
response may vary between populations of the same species on a small spatial and …

In mammals, species with highly male-biased sexual size dimorphism tend to have high
variance in male reproductive success. However, little information is available on patterns of …

Determining sex-bias in brain structure is of great societal interest to improve diagnostics
and treatment of brain-related disorders. So far, studies on sex-bias in brain structure …

Sociality modulates life-history traits through changes in resource allocation to fitness-
related traits. However, how social factors at different stages of the life cycle modulate …

Redclaw crayfish (Cherax quadricarinatus) was introduced to China many years ago. In
recent years, a breeding boom for C. quadricarinatus has been set off in China due to a …

Many polygynous, capital breeders exhibit sexual dimorphism with respect to body size and
composition. Sexual dimorphism is often facilitated by sex differences in foraging behavior …

The different reproductive roles of the sexes can predict the direction and magnitude of
sexual dimorphism of external and internal morphology. Males should have enlarged …
