I am a plant biologist from the National Autonomous University of Mexico (UNAM), specially interested in the ecological, geographical and historical factors that influence species and gene diversities at different spatial scales. I’ve spent the last five years studying the climatic history of cloud forest species in the northern Neotropics, focusing on the demographic history, population genetics and ecology of scaly tree ferns (Cyatheaceae). Together with several colleagues, I’m currently studying the relationship between population genetic structure, ecological niches, morphological evolution and species diversification in tree ferns. For this, we are studying different aspects of tree fern evolution: genetic structure within and among populations, species diversification rates among lineages, community composition, pattern of species distribution and the presence of cryptic lineages. I’m also addressing these questions in other biological systems, particularly recently diversified groups of plants species in the Neotropics. Currently, I’m involved in a project dealing with the systematics, spatial genetics, species diversification and morphological evolution in loranth mistletoes (Loranthaceae). I’m also part of a collaborative effort to understand the temporal and spatial patterns of extant species accumulation in the families of flowering plant.
