Cladistic biogeography of the Mexican transition zone
Journal of Biogeography, 2000AbstractBiogeographic relationships among nine montane areas of endemism across the transition zone between North and South America are analysed cladistically based on phylogenetic hypotheses of thirty‐three resident monophyletic taxa of insects, fish, reptiles, and plants.Areas of endemism include the Arizona mountains (AZ), Sonoran Desert (SD ...

Gymnosperms and cladistic biogeography of the Mexican Transition Zone
TAXON, 2007Distributional patterns of 81 species of three genera of Mexican gymnosperms ( Ceratozamia, Dioon, Pinus ) were analyzed to evaluate their contribution to the cladistic biogeography of the Mexican Transition Zone, applying Brooks Parsimony Analysis (BPA) and parsimony analysis of paralogy ...

AbstractAimMost biodiversity studies have considered species to be isolated entities, neglecting the fact that their biotic interactions and spatial variation are fundamental to their persistence across elevational gradients. Here, using a standardized sampling methodology, we evaluated how and why the composition of flower–visitor interactions (i.e ...

Zootaxa, 2005
A new flea species, Hystrichopsylla cryptotis, is described from the Sierra Madre Oriental and Sierra Madre del Sur, Mexico. The host of this new species is the shrew Cryptotis mexicana (Coues, 1877) (Mammalia: Soricidae). This flea species is easily recognized by its large size, seven genal combs, and the slender sternum IX, with 13 pairs of thick ...

AbstractGenomic data continue to advance our understanding of species limits and biogeographic patterns. However, there is still no consensus regarding appropriate methods of phylogenomic analysis that make the best use of these heterogeneous data sets.

Invertebrate Systematics, 2013
We incorporated new data to re-evaluate the biogeographical patterns in the Mexican Transition Zone (MTZ) through the recognition of congruence in the geographic distributions of Mexican passalids (Coleoptera : Passalidae). We used three different approaches to parsimony analysis of endemicity (PAE): (1) the use of specific distribution data; (2) the ...

The genus Pinguicula (Lentibulariaceae) is composed of 115 species of carnivorous plants and Mexico is a center of diversification. The Mexican Transition Zone (MTZ) is the boundary between the Nearctic and Neotropical regions. It includes the main mountain ranges of Mexico, which extend south to northeastern Nicaragua.

Organisms Diversity & Evolution, 2013
The role of horizontal and vertical colonization on the diversity and integration of the dung beetle fauna of two mountains in the Mexican Transition Zone (Los Tuxtlas and La Chinantla) are analyzed and compared. On each mountain standardized sampling was done using pitfall traps baited with dung and carrion along elevation gradients. On both mountains

Halffter (1976), in an attempt to explain the origin and dispersal of Neotropical insects in North America, developed a theory of reference models, with which the distribution of a given group can be compared. He characterized dispersal in the Mexican Transition Zone (the southern U.S., Mexico and most of Central America), and grouped patterns by ...
