The integration processes of the distributional patterns in the Mexican Transition Zone: Phyletic, paleogeographic and ecological factors of a case study

Zootaxa, 2019
In this study, we take the Onthophagus chevrolati species group, likely a monophyletic species group as an example to analyze the processes that led to the biogeographic integration of the Holarctic fauna in the mountains of the Mexican Transition Zone to test our biogeographic hypotheses.

Analysing the assembly of cenocrons in the Mexican transition zone through a time-sliced cladistic biogeographic analysis

Australian Systematic Botany, 2017
A transition zone shows the overlap between two or more regions and represents an event of biotic hybridisation, where different cenocrons assembled as a result of historical and ecological processes. The Mexican transition zone, the area where the Nearctic and Neotropical regions overlap, includes the following five biogeographical provinces: Sierra ...

Phylogenomics of alligator lizards elucidate diversification patterns across the Mexican Transition Zone and support the recognition of a new genus

Biological Journal of the Linnean Society, 2021
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.

Areas of endemism persist through time: A palaeoclimatic analysis in the Mexican Transition Zone

Journal of Biogeography, 2018
AbstractAimThe Mexican Transition Zone (MTZ) is an area where the Nearctic and Neotropical biogeographical regions overlap, generating high species richness and endemism. The objective of this study was to analyse if potential changes in the composition and the geographical location of areas of endemism (AEs) for beetles and mammals during the Last ...

The Distribution of Southwest North American Mayfly Genera (Ephemeroptera) in the Mexican Transition Zone

1990
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 ...

Cladistic biogeography of the Mexican transition zone

Journal of Biogeography, 2000
AbstractBiogeographic 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 ...

Temperature dissimilarity drives flower–visitor interaction turnover across elevation in the Mexican Transition Zone

Journal of Biogeography, 2023
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 ...

A new species of Hystrichopsylla Taschenberg (Siphonaptera: Hystrichopsyllidae) from the Mexican transition zone

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 ...
