Over the years ecologists have shown how biological diversity benefits the health of small, natural communities. New analysis by ecologists at UC Santa Cruz demonstrates that even higher levels of biological diversity are necessary to maintain ecosystem health in larger landscapes over long periods of time. Think of it as patches on a quilt, says Erika Zavaleta, UCSC associate professor of environmental studies. Each patch may be a diverse habitat of plants, animals, and insects but it is...

Long-term study finds that each species plays a role in maintaining a productive ecosystem Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present, results of a new study show. The long-term study of plant biodiversity found that each species plays a role in maintaining a productive ecosystem, especially when a long time horizon is considered. The research found that every additional species in a plot...
