Patterns of Richness and Endemism in the Gypsicolous Flora of Mexico
Gypsum soils occur around the world, mainly in arid regions. These harsh environments promote unusual flora with high degrees of endemism. Mexico has extensive gypsum outcrops, but their flora has been poorly studied.

Phylogenetic endemism of the orchids of Megamexico reveals complementary areas for conservation
Orchid diversity provides a unique opportunity to further our understanding of biotic and abiotic factors linked to patterns of richness, endemism, and phylogenetic endemism in many regions. However, orchid diversity is consistently threatened by illegal

Delimiting areas of endemism through kernel interpolation. [PDF]
We propose a new approach for identification of areas of endemism, the Geographical Interpolation of Endemism (GIE), based on kernel spatial interpolation. This method differs from others in being independent of grid cells.
