Climatic controls on the global distribution, abundance, and species richness of mangrove forests Climatic controls on the global distribution, abundance, and species richness of mangrove forests
Mangrove forests are highly productive tidal saline wetland ecosystems found along sheltered tropical and subtropical coasts. Ecologists have long assumed that climatic drivers (i.e., temperature and rainfall regimes) govern the global distribution, structure, and function of mangrove forests. However, data constraints have hindered the quantification of direct climate-mangrove linkages...

Using structural equation modeling to link human activities to wetland ecological integrity Using structural equation modeling to link human activities to wetland ecological integrity
The integrity of wetlands is of global concern. A common approach to evaluating ecological integrity involves bioassessment procedures that quantify the degree to which communities deviate from historical norms. While helpful, bioassessment provides little information about how altered conditions connect to community response. More detailed information is needed for conservation and...

Does urban sprawl hold down upward mobility? Does urban sprawl hold down upward mobility?
Contrary to the general perception, the United States has a much more class-bound society than other wealthy countries. The chance of upward mobility for Americans is just half that of the citizens of the Denmark and many other European countries. In addition to other influences, the built environment may contribute to the low rate of upward mobility in the U.S. This study tests the...

Disentangling vegetation diversity from climate–energy and habitat heterogeneity for explaining animal geographic patterns Disentangling vegetation diversity from climate–energy and habitat heterogeneity for explaining animal geographic patterns
Broad-scale animal diversity patterns have been traditionally explained by hypotheses focused on climate–energy and habitat heterogeneity, without considering the direct influence of vegetation structure and composition. However, integrating these factors when considering plant–animal correlates still poses a major challenge because plant communities are controlled by abiotic factors...

Comment on "Worldwide evidence of a unimodal relationship between productivity and plant species richness" Comment on "Worldwide evidence of a unimodal relationship between productivity and plant species richness"
Fraser et al. (Reports, 17 July 2015, p. 302) report a unimodal relationship between productivity and species richness at regional and global scales, which they contrast with the results of Adler et al. (Reports, 23 September 2011, p. 1750). However, both data sets, when analyzed correctly, show clearly and consistently that productivity is a poor predictor of local species richness.

Integrative modelling reveals mechanisms linking productivity and plant species richness Integrative modelling reveals mechanisms linking productivity and plant species richness
How ecosystem productivity and species richness are interrelated is one of the most debated subjects in the history of ecology. Decades of intensive study have yet to discern the actual mechanisms behind observed global patterns. Here, by integrating the predictions from multiple theories into a single model and using data from 1,126 grassland plots spanning five continents, we detect...
