Journal ArticleDOI
Functional diversity supports the physiological tolerance hypothesis for plant species richness along climatic gradients
TL;DR: It is found that functional diversity was higher in more favourable climatic conditions (mesic slopes) and that multivariate functional diver- sity mediated the relationship of the topographic climate gradient to plant species richness.
Journal ArticleDOI
Multivariate control of plant species richness and community biomass in blackland prairie
TL;DR: In this article, structural equation modeling was used to investigate how soil characteristics and shade by scattered Juniperus virginiana trees relate to standing biomass and species richness in 99 0.25 m2 quadrats collected in eastern Mississippi, USA.
Journal ArticleDOI
The interacting roles of climate, soils, and plant production on soil microbial communities at a continental scale

TL;DR: It is highlighted that soil microbial communities can be modeled within the context of multiple interacting ecosystem properties acting both directly and indirectly on their composition and function, and this provides a rich and informative context with which to examine communities.
Journal ArticleDOI
Invasion in a diversity hotspot: exotic cover and native richness in the Californian serpentine flora.
TL;DR: The results suggest that, in spite of some localized impacts, exotic species are not exerting a detectable overall effect on the community richness of the unique native flora of Californian serpentine.
Journal ArticleDOI
Growth and invasive potential of Sapium sebiferum (Euphorbiaceae) within the coastal prairie region: the effects of soil and moisture regime.
TL;DR: Soil analyses revealed the highest sand, sodium, and phosphorus contents, and much higher electrical conductivity in the western soil, and it was concluded that the soil examined from the western region is unfavorable for S. sebiferum growth, though not to the extent to preclude S. biferum completely.
