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 ...

Current claims of biodiversity crisis call for immediate conservation actions. These require the identification of priority sites for conservation based on an assessment of biodiversity patterns. Patterns of species richness are crucial in such endeavor. Also rarity, measured by the size of species' geographical ranges, is often used as a single or complementary criterion. For instance, hotspots for conservation have been defined using either one or the other criterion. We apply a novel tool, range– ...

Explaining the causes of geographic gradients in biodiversity remains an elusive task. Traditionally, correlative approaches have been used to relate species richness with contemporary climate, without actually explaining the causal factors. Recent approaches propose simulation models as more appropriate tools for assessing potential causes of macroecological patterns. Here we developed stochastic models to assess the relative contribution of climate and niche conservatism in determining compositional ...

We assess the changes in Mexico's privately owned vehicle fleet and tax losses (fuel duty on gasoline) associated to the deployment of electric vehicles (EVs) through a diffusion model. Our projections for 2050 focus on a) electricity use of EVs, b) gasoline use and c) revenue for Mexico's treasury. The model uses population growth and vehicles sales to project two items: a) EV diffusion and b) substitution rates of ICVs with EVs. The equation uses vehicle km travelled and average consumption of fuel ...

Mexico harbors great cultural and ethnic diversity, yet fine-scale patterns of human genome-wide variation from this region remain largely uncharacterized. We studied genomic variation within Mexico from over 1000 individuals representing 20 indigenous and 11 mestizo populations. We found striking genetic stratification among indigenous populations within Mexico at varying degrees of geographic isolation. Some groups were as differentiated as Europeans are from East Asians. Pre-Columbian genetic ...

Aminopeptidase-N (APN1) and alkaline phosphatase (ALP) proteins located in the midgut epithelium of Manduca sexta have been implicated as receptors for Cry1Aa, Cry1Ab, and Cry1Ac insecticidal proteins produced by Bacillus thuringiensis subsp. kurstaki. In this study, we analyzed the roles of ALP and APN1 in the toxicity of these three Cry1A proteins. Ligand blot analysis using brush border membrane vesicles of M. sexta showed that Cry1Aa and Cry1Ab bind preferentially to ALP during early instars while ...

Using a random, combinatorial scheme of mutagenesis directed against the conserved SDN region of TEM β-lactamase, and selective screening in ampicillin-plates, we obtained the N132D mutant enzyme. The kinetic characterization of this mutant indicated relatively small effects compared to the wild-type. Both pK1 and pK2 for catalysis were decreased about 1 unit relative to the pK′s for the wild type. This effect was predominantly due to changes in Km . In contrast to the wild-type, the pH-rate profiles ...

The diversity of sites and the distribution of species are fundamental pieces in the analysis of biogeographic and macroecological questions. A link between these two variables is the correlation between the species diversity of sites and the mean range size of species occurring there. Alternatively, one could correlate the range sizes of species and the mean species diversity within those ranges. Here we show that both approaches are mirror images of the same patterns, reflecting fundamental mathematical ...
