Introduction
I am an entomologist interested in studies with a focus on taxonomy, phylogenetic systematics, historical biogeography, geometric morphometry and biological conservation, and I use the Coleoptera order as a model group, although I am also interested in applying the analytical tools of these disciplines to other groups of organisms. ​My study group, the order Coleoptera, is the most diverse taxon in the animal kingdom, with great ecological and economic importance...

Chapter
Las larvas de Coleopteros del género Phyllophaga representan un riesgo para la seguridad alimentaria en Oaxaca y todo México. Para México las pérdidas - brada, mientras que para el estado de Oaxaca los daños llegan hasta el 90%. El objetivo del trabajo es determinar qué zonas agrícolas están en mayor ries- go por Phyllophaga en escenarios de cambio...
Article
Deforestation and land use changes are major drivers of biodiversity decline. At the genetic level, these human activities restrict gene flow and increase the effects of genetic drift and inbreeding, reducing a populations’ capacity to respond and adapt to changing environments. We pro- duced novel genomic data (Single Nucleotide Polymorphisms [SNP...
Article
1. Ecological niche models and species distribution models (SDMs) are tools used to define a species’ niche based on presence records and to identify areas where appropriate ecological conditions converge, indicating zones of potential distribution for the species. SDMs help optimize conservation efforts, which is particularly important in countrie...

Insects are the most diverse group of organisms, but their large number of species and the lack of specialists to study them have made this group particularly vulnerable to the main limitations in biological diversity, such as the Wallacean deficit. This study will contribute to the geographical knowledge of an insect trophic guild that has been wi...
