Body size evolution in mammals: complexity in tempo and mode
COOPER, NATALIE; PURVIS, ANDY (University of Chicago Press, 2010)Body size correlates with virtually every aspect of species? biology, so understanding the tempo and mode of its evolution is of key importance in macroecology and macroevolution. Here we use body-mass data from 3473 of ... -
A common tendency for phylogenetic overdispersion in mammalian assemblages
COOPER, NATALIE; RODRIGUEZ, JESUS; PURVIS, ANDY (The Royal Society, 2008)Competition has long been proposed as an important force in structuring mammalian communities. Although early work recognised that competition has a phylogenetic dimension, only with recent increases in the availability ... -
Macroecology and extinction risk correlates of frogs
COOPER, NATALIE; BIELBY, JON; THOMAS, GAVIN H; PURVIS, ANDY (Blackwell Publishing, 2008)Aim Our aim was to test whether extinction risk in frogs could be predicted from their body size, fecundity or geographic range size. Because small geographic range size is a correlate of extinction risk in many taxa, we ... -
What factors shape rates of phenotypic evolution? A comparative study of cranial morphology of four mammalian clades
COOPER, NATALIE; PURVIS, ANDY (2009)Understanding why rates of morphological evolution vary is a major goal in evolutionary biology. Classical work suggests that body size, interspecific competition, geographic range size and specialisation may all be ...
