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 …

Body size affects important fitness variables such as mate selection, predation and tolerance
to heat, cold and starvation. It is therefore subject to intense evolutionary selection. Recent …

Many male animals wield ornaments or weapons of exaggerated proportions. We propose
that increased cellular sensitivity to signaling through the insulin/insulin-like growth factor …

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 …

1. Classic evolutionary models interpret ageing as a cost of reproduction, but evolutionary
research has thus far largely neglected the conceptual links between the evolution of ageing …

Publisher Summary This chapter discusses the juvenile hormones (JH). The JH, a family of
acyclic sesquiterpenoids, are essential to insect development and reproduction. This …

Insects are the most ecologically important multicellular heterotrophs in terrestrial systems.
They play critical roles in ecological food webs, remain devastating agricultural and medical …

Phenotypic plasticity is a fascinating concept of immense importance to biology Like
evolutionary theory, phenotypic plasticity is all-encompassing, connecting virtually all fields …

The integration of evolutionary biology with developmental genetics into the hybrid field of
'evo-devo'resulted in major advances in understanding multicellular development and …

Developmental bias, or genetic channeling, can influence the tempo and direction of
evolution and, thus, become reflected in patterns of biodiversity. Twenty years ago, this …
