Patterns of Richness and Endemism in the Gypsicolous Flora of Mexico

open access: yesDiversity, 2023
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

open access: yesPlant Diversity, 2022
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

Areas of endemism of two biogeographic provinces in central Mexico based on their endemic Asteraceae: a conservation proposal

open access: yesRevista Mexicana de Biodiversidad, 2021
The Transmexican Volcanic Belt (TVB) and the Balsas Basin (BB), situated in central Mexico, stand out for their species richness and endemism. Documenting patterns of distribution of endemism is relevant, since species restricted to an area may become ...

Delimiting areas of endemism through kernel interpolation. [PDF]

open access: yesPLoS ONE, 2015
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.

Biogeographic analysis of the American genus Echeandia (Agavoideae: Asparagaceae)

open access: yesRevista Mexicana de Biodiversidad, 2021
Echeandia (Asparagaceae) is an American genus of herbaceous geophytes. Its distribution is heterogeneous but concentrates along the Mexican Transition Zone (MTZ). We analyzed the species richness distribution and endemism of the group.

Distribution of freshwater fish from the Southern Neotropics reveals three new areas of endemism and show diffuse limits among freshwater ecoregions

open access: yesNeotropical Ichthyology, 2021
Ecoregions and areas of endemism are central concepts in biogeography. Based on collection records and the Endemic Analyses implemented with NDM/VNDM method we analyzed fish areas of endemism in the junction of three freshwater ecoregions related to the ...
