We integrate field data and phylogenetic comparative analyses to investigate causes of
body size evolution and stasis in an old insect order: odonates (“dragonflies and …

Cope's Rule is the tendency for organisms in evolving lineages to increase in size over time.
The concept is detailed in many textbooks, but has rarely been demonstrated. Many …

The relationship between body size and fitness components in odonates was examined
using a meta‐analysis of 33 published studies. There was a positive and significant overall …

1. Body size is a central element in current theories of life‐history evolution. Models for
optimal age at maturity are based on the assumptions that there is a trade‐off between …

Highlights•Allometry describes the relationship between organ and body size.•Changes in
allometry generate the vast diversity of animal shapes.•Understanding how allometry …

The evolution of body size is a dominant feature of animal evolution. However, little is known
about how the underlying developmental mechanisms that determine size change as body …

Sokolovska et al.(2000) used 57 weighted correlation coefficients derived from 33 published
studies of 20 species to produce the first meta-analysis of body size and fitness in odonates …

Body size is a key feature of organisms and varies continuously because of the effects of
natural selection on the size‐dependency of resource acquisition and mortality rates. This …

Body size is one of the most important life history characters of organisms, yet little is known
of the physiological mechanisms that regulate either body size or variation in body size …

The recent “overhead threshold” model for optimal age and body size at maturity (Day and
Rowe) predicts that phenotypic variability in adult body size will be low under inferior …
