A Globally Consistent Richness‐Climate Relationship for Angiosperms. Export

@article{citeulike:4612260, abstract = {doi: 10.1086/368223 PMID: 12776882 Species richness, the simplest index of biodiversity, varies greatly over broad spatial scales. Richness‐climate relationships often account for >80\% of the spatial variance in richness. However, it has been suggested that richness‐climate relationships differ significantly among geographic regions and that there is no globally consistent relationship. This study investigated the global patterns of species and family richness of angiosperms in relation to climate. We found that models relating angiosperm richness to mean annual temperature, annual water deficit, and their interaction or models relating richness to annual potential evapotranspiration and water deficit are both globally consistent and very strong and are independent of the diverse evolutionary histories and functional assemblages of plants in different parts of the world. Thus, effects of other factors such as evolutionary history, postglacial dispersal, soil nutrients, topography, or other climatic variables either must be quite minor over broad scales (because there is little residual variation left to explain) or they must be strongly collinear with global patterns of climate. The correlations shown here must be predicted by any successful hypothesis of mechanisms controlling richness patterns.}, author = {Francis, Anthony p and Currie, David j}, citeulike-article-id = {4612260}, citeulike-linkout-0 = {http://dx.doi.org/10.1086/368223}, citeulike-linkout-1 = {http://www.journals.uchicago.edu/doi/abs/10.1086/368223}, day = {1}, doi = {10.1086/368223}, journal = {The American Naturalist}, keywords = {diversity, plant, test}, month = {April}, number = {4}, pages = {523--536}, posted-at = {2009-05-23 18:38:07}, priority = {2}, title = {A Globally Consistent Richness‐Climate Relationship for Angiosperms.}, url = {http://dx.doi.org/10.1086/368223}, volume = {161}, year = {2003} }
