La increíble diversidad específica y ecosistémica sitúan a México entre los países megadiversos del planeta. Los patrones biogeográficos de taxones país también muestran una notable complejidad. parte norte se sitúa en la región Neártica, mientras que austral pertenece Neotropical. Entre ambas, principalmente las sierras Madre Faja Volcánica Transmexicana, mezcla neárticos neotropicales determina Zona Transición Mexicana. Esta encrucijada biótica hace sea tan interesante, no solo términos sus especies endémicas, sino cuanto variadas relaciones filogenéticas hipótesis han formulado para explicar cómo orígenes diversos, ensamblado Adicionalmente, el posee casi todos tipos vegetación, con desiertos, bosques tropicales templados, pastizales yermos alta montaña.

Why biogeographical transition zones matter

Journal of Biogeography, Journal Year: 2023, Volume and Issue: 51(4), P. 544 - 549

Published: May 24, 2023

Abstract Biogeographical transition zones are areas of overlap, replacement or partial segregation between different biotas, which sets taxa sharing similar geographical distributions as a result common evolutionary history and ecological affinities. Transition occur in few particular the world where historically contingent processes have allowed biotic elements to coexist interact. Evolutionary historical biogeographers traditionally characterized by overlap elements. More recently, authors applying track analyses detected presence nodes conflicting results cladistic biogeographic analyses. Ecological taken approach, usually quantitative methods, for example, species turnover indices analyse strength breadth zones. Some consider represent outstanding analysing principles shaping assembly, whereas others dismissed them, sometimes artificial. particularly interesting truly integrative biogeography, being natural laboratories interaction can be analysed fruitfully, especially appropriate an epistemologically grounded pluralism. A coherent conceptual framework zones, however, is still lacking.

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

Abstract Aim The Mexican Transition Zone ( MTZ ) is an area where the Nearctic and Neotropical biogeographical regions overlap, generating high species richness endemism. objective of this study was to analyse if potential changes in composition geographical location areas endemism (AEs) for beetles mammals during Last Glacial Maximum LGM ), mid‐Holocene MH or Interglacial LIG have influenced definition present.

A novel approach to time-slicing areas within biogeographic-area classifications: Wallacea as an example

Australian Systematic Botany, Journal Year: 2017, Volume and Issue: 30(6), P. 495 - 495

Published: Jan. 1, 2017

Time-slicing of areas is a novel biogeographic method that helps resolve conflicting area relationships and assess temporal overlap as an explanation for the conflict. The differs from others currently popular in biogeography it does not date nodes before analysis (e.g. divergence dating) to infer classification. Here, time-slicing used proof concept approach interpret inter-relationships Neogene Palaeogene biotic Wallacea, well-studied between South-East Asia Australasia.

Track analysis of the Nearctic region: Identifying complex areas with mammals

Journal of Zoological Systematics & Evolutionary Research, Journal Year: 2018, Volume and Issue: 56(3), P. 466 - 477

Published: Feb. 6, 2018

The Nearctic region is located on the North American plate. However, its tectonic history related to convergence with other plates, which has promoted a complex topography. This complexity should be reflected by distributional patterns of biota. We used track analysis 574 species mammals identify generalized tracks and panbiogeographic nodes in propose an updated point view areas their boundaries America.

Abstract This is the first report evaluating genetic diversity of Mexican grape species utilizing DNA-based markers to understand distribution species, and patterns hybridization. The study utilized accessions maintained in three collections Mexico, one USA recently collected germplasm. Fifteen SSR were used develop a fingerprint database identify unique Two different clustering analyses without prior population assignment, groups that verified by Discriminant Analysis Principal Components Coordinate Analysis. Genetic estimates made across within validate results obtained from analyses. Multiple parameters supported six representing geographic regions. Northeastern group was most diverse with range extending Eastern Central while Coahuila least diverse. Vitis arizonica Engelm. cinerea ex Millardet abundant many hybrid forms. We provide evidence wild Mexico follow physical barriers mountain ranges like Sierra Madre Oriental an east–west divide Trans-Mexican Volcanic Belt as corridor for gene flow among species.
