We use complete species–level phylogenies of extant Carnivora and Primates to perform
the first thorough phylogenetic tests, in mammals, of the hypothesis that small body size is …

Background Little is known about the long-term patterns of body size evolution in
Crocodylomorpha, the> 200-million-year-old group that includes living crocodylians and …

Body size is a central feature of any organism, reflecting its physiology, ecology and
evolutionary history. Marine microplankton are major contributors to the particulate inorganic …

Summary 1 The prominently right‐skewed distribution of species sizes has been the subject
of a large literature in animal ecology, but has received comparatively little attention from …

The distribution of species body size is critically important for determining resource use
within a group or clade. It is widely known that non-avian dinosaurs were the largest …

Phylogenetic relationships were reconstructed for salamanders of the plethodontid
subfamily Desmognathinae to examine evolution of morphology, ecology, and life history …

Size bias in the fossil record limits its use for interpreting patterns of past biodiversity and
ecological change. Using comparative size frequency distributions of exceptionally good …

▪ Abstract Historically, a great many features of organisms have been said to show a trend
over the history of life, and many rationales for such trends have been proposed. Here I …

Interspecific interactions affect habitat use and subsequent morphological adaptation in
Anolis lizards. We examined populations of two species of Anolis lizards that evolved in the …

Body size is of fundamental importance in understanding macroevolutionary patterns, both
for extant taxa and for those with a fossil record. In this paper we describe four different kinds …
