| description | Beta diversity, or species turnover, is a poorly understood component of species richness. In the case of Mexico, empirical evidence shows that beta diversity is a more important determinant of regional diversity than the alpha or local component. Therefore, the unusual species richness of Mexico is more a consequence of a strong geographic species turnover rather than a particularly high local diversity. The hypothesis of Mexico as a beta- diverse country is based not only on indirect inferences but on data that have been accumulated in the scientific literature in the last few years. In this paper, we review that information and present new analyses that explore the contribution of species turnover to the building of the megadiversity of Mexican mammals. In an analysis using latitudinal bands, we found that the pattern of variation of beta diversity along a latitudinal gradient is similar for volant and non-volant mammals. However the patterns of diversity of terrestrial mammals are much more associated to beta diversity. In exploring beta diversity within biogeographic provinces defined with the distribution of mammals, we found that the relative contribution of alpha and beta diversity to the regional species richness varies geographically and is correlated with different environmental variables. We also present data showing the effect of heterogeneity on alpha and beta diversity, and show a direct relationship between beta diversity and the complementarity among sites in selecting priority areas for the conservation of biological diversity. |

De los componentes de la riqueza de especies, la diversidad beta o recambio de especies es el que menos atención ha recibido. En el caso de México, la evidencia empírica apunta a que la diversidad beta, más que la diversidad alfa o local, es el componente más importante para explicar la extraordinaria diversidad de especies en el ámbito nacional. La hipótesis del México betadiverso se sustenta tanto en inferencias indirectas como en datos que se han ido acumulando en la literatura científica. En este trabajo revisamos esa información y presentamos análisis nuevos que examinan la contribución del recambio de especies a la conformación de la megadiversidad de mamíferos de México. Usando un análisis de bandas latitudinales, se encontró un patrón de variación de la diversidad beta respecto a la latitud similar para quirópteros y mamíferos terrestres. Sin embargo el recambio de especies es un componente asociado en mayor medida a los patrones de diversidad de los mamíferos terrestres. Al explorar la diversidad beta dentro de las provincias mastofaunísticas del país, se encontró que la contribución de las diversidades alfa y beta a la diversidad gamma varían geográficamente y se correlacionan con distintas variables ambientales. Se presentan también datos que muestran el efecto de la heterogeneidad ambiental sobre la diversidad alfa y beta y se muestra cómo la diversidad beta está relacionada con la complementariedad como estrategia para seleccionar sitios prioritarios para la conservación.
