          Abstract

          Se analizan los patrones biogeográficos de diversidad y endemismo de la mastofauna mexicana, dentro en un cuadrante comprendido entre los 15º 30' y 21º 00' de latitud N y 94º 00' y 100º 00' de longitud W, con el objetivo de identificar a la provincia Oaxaca-Tehuacanense como una unidad natural. Se analizaron los registros de 133 especies de mamíferos en bases de datos y se modelaron sus distribuciones potenciales. Usando los modelos de distribución potencial, se generó un mapa de diversidad y se llevó a cabo un análisis de endemicidad. El mapa de diversidad presenta un gradiente latitudinal de riqueza de especies, donde la mayor diversidad se ubica en los límites de los estados de Oaxaca y Veracruz, debido probablemente a que es un área límite entre provincias y nodo biogeográfico. El análisis de endemismo identificó un área (área de consenso No. 14) compuesta por tres especies endémicas (Habromys simulatus, Microtus quasiater y Megadontomys nelsoni), como provincia biogeográfica, cuyos límites son más amplios a los propuestos por Ramírez-Pulido y Castro-Campillo (1990) para la Oaxaca-Tehuacanense. Se concluye que la Oaxaca-Tehuacanense es una provincia biogeográfica que, dado el patrón de diversidad de mamíferos, probablemente cuenta con un alto número de otros grupos biológicos, entre los cuales existen especies de distribución restringida e importancia evolutiva, los cuales pueden ser criterios que permiten priorizar más eficientemente las estrategias de conservación.

          We analyzed the biogeographical patterns of diversity and endemicity of the Mexican mammals, into a quadrat between 15º 30' - 21º 00' N latitude and 94º 00' - 100º 00' W longitude, in order to identify the Oaxaca-Tehuacanense province as a natural area. We analyzed the records of 133 mammalian species in databases and we modeled their distributions. Using the potential distribution models, we built a diversity map and performed an endemicity analysis. The diversity map shows an important latitudinal gradient of species richness, where the highest diversity is in boundaries of Oaxaca and Veracruz, and it can be due to the boundaries of provinces and a probable biogeographic node. The analysis of endemicity identified an area (area of consensus No. 14) with three endemic species (Habromys simulatus, Microtus quasiater and probably Megadontomys nelsoni) as biogeographic province, with boundaries wider than the Ramírez-Pulido and Castro-Campillo's (1990) Oaxaca-Tehuacanense province. We concluded that the Oaxaca-Tehuacanense province, given its pattern of richness of mammals, probably has high number of biological groups, some of them are species with restricted distribution and evolutive importance, which can be used as criteria to prioritize with efficience the conservation strategies.

              Biogeographic areas and transition zones of Latin America and the Caribbean islands based on panbiogeographic and cladistic analyses of the entomofauna.

              Track and cladistic biogeographic analyses based on insect taxa are used as a framework to interpret patterns of the Latin American and Caribbean entomofauna by identifying biogeographic areas on the basis of endemicity and arranging them hierarchically in a system of regions, subregions, dominions, and provinces. The Nearctic region, inhabited by Holarctic insect taxa, comprises five provinces: California, Baja California, Sonora, Mexican Plateau, and Tamaulipas. The Mexican transition zone comprises five provinces: Sierra Madre Occidental, Sierra Madre Oriental, Transmexican Volcanic Belt, Balsas Basin, and Sierra Madre del Sur. The Neotropical region, which harbors many insect taxa with close relatives in the tropical areas of the Old World, comprises four subregions: Caribbean, Amazonian, Chacoan, and Parana. The South American transition zone comprises five provinces: North Andean Paramo, Coastal Peruvian Desert, Puna, Atacama, Prepuna, and Monte. The Andean region, which harbors insect taxa with close relatives in the Austral continents, comprises three subregions: Central Chilean, Subantarctic, and Patagonian.
