While most research on the relationship between ecosystem diversity and stability has focused on species richness, it is variation in species composition that provides the mechanistic basis to ...
The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems. Biological diversity, often shortened to biodiversity, is ...
A formula can be used to predict what happens when a new species is introduced into an ecosystem -- whether it will establish itself in the community or fail to gain a foothold and die out.
Fire is a natural, vital component of most western forest ecosystems. In dry forest types like ponderosa pine, fire was historically present as a frequent, low-intensity disturbance. Fire is necessary ...
