Healthy ecosystems include many species (high richness) with similar abundances (high evenness). Thus, both aspects of biodiversity are worthy of conservation. Simultaneously conserving richness and evenness might be difficult, however, if, for example, the restoration of previously absent species to low densities brings a cost in reduced evenness. Using meta‐analysis, we searched for benefits to biodiversity following adoptio...

Ecology Letters (2012) 15 : 378–392 Abstract Forest trees are the dominant species in many parts of the world and predicting how they might respond to climate change is a vital global concern. Trees are capable of long‐distance gene flow, which can promote adaptive evolution in novel environments by increasing genetic variation for fitness. It is unclear, however, if this can compensate for maladaptive effects of gene flow and...

Conservation biologists often must make decisions about the sustainability of harvest rates based on minimal demographic information. To assist them formulated a method to estimate maximum rates of production which could be used to detect overharvesting based on only age at first reproduction, fecundity, and maximum longevity. By assuming constant adult survival, we reduced the Euler equation to a simple form that allows calcu...
