Chemical mimicry of insect oviposition sites: a global analysis of convergence in angiosperms.

abstract：:Theory argues that both soil conditions and aboveground trophic interactions have equivalent potential to limit or promote plant diversity. However, it remains unexplored how they jointly modify the niche differences stabilising species coexistence and the average fitness differences driving competitive dominance. We ...

There is ambiguity in which competitive steps are included in measures of sexual selection: individuals who fail to obtain resources necessary for reproduction are often excluded. We illustr...
