Seed dormancy is an innate seed property that defines the environmental conditions in
which the seed is able to germinate. It is determined by genetics with a substantial …

Recent attempts to address the long-debated 'origin'of the angiosperms depend on a
phylogenetic framework derived from a matrix of taxa versus characters; most assume that …

Wood density is a crucial variable in carbon accounting programs of both secondary and old
growth tropical forests. It also is the best single descriptor of wood: it correlates with …

Numerous ecological and evolutionary processes are thought to play a role in maintaining
the high plant species diversity of tropical forests. An understanding of the phylogenetic …

Background Plant-feeding insects make up a large part of earth's total biodiversity. While it
has been shown that herbivory has repeatedly led to increased diversification rates in …

The problem of scale dependency is widespread in investigations of ecological
communities. Null model investigations of community assembly exemplify the challenges …

We report herein the application of a set of algorithms to identify a large number (2869) of
single-copy orthologs (COSII), which are shared by most, if not all, euasterid plant species …

Theory has long predicted that insect community structure should be related to host plant
phylogeny. We examined the distribution of insect herbivore associations with respect to …

Seventynine species representing 12 genera of Vitaceae were sequenced for the trnLF
spacer, 37 of which were subsequently sequenced for the atpBrbcL spacer and the rps16 …

A significant proportion of the global diversity of flowering plants has evolved in recent
geological time, probably through adaptive radiation into new niches. However, rapid …
