Introduction
I am an evolutionary biologist and ecologist interested in understanding the processes that have created and shaped tropical biodiversity at species and genetic level. For this purpose, I use dated phylogenetic reconstructions, population genetic analyses, ecological niche modelling, and field-based approaches. I aim that my research contributes to the conservation of ecologically and economically important species, their genetic diversity, and the ecosystems they inhabit.

Article
The palm tribe Phytelepheae form a clade of three genera and eight species whose phylogenetic relationships and historical biogeography are not fully understood. Based on morphological similarities and phylogenetic relatedness, it has been suggested that Phytelephas seemannii and Phytelephas schottii are synonyms of Phytelephas macrocarpa, implying...

AIM Pleistocene (2.58 Ma–11.7 ka) climatic fluctuations have shaped intraspecific genetic patterns worldwide; however, their impact on species in many regions remains unknown. In order to determine the impact of Pleistocene climatic fluctuations on the tropical rain forests of western Ecuador, we explored the evolutionary history of the endemic pal...

Post-dispersal seed removal by ground-foraging frugivores promotes secondary dispersal of large seeds, reducing seed predation and increasing recruitment and regeneration. We studied how habitat disturbance influences seed removal patterns in the large-seeded palm Phytelephas aequatorialis within three habitats forming a continuum of disturbance (a...

Andean orogenesis has driven the development of very high plant diversity in the Neotropics through its impact on landscape evolution and climate. The analysis of the intraspecific patterns of genetic structure in plants would permit inferring the effects of Andean uplift on the evolution and diversification of Neotropical flora. In this study, usi...

Phytelephas aequatorialis is the commercially exploited ivory palm in western Ecuador, where less than 25% of the natural forest remains. To determine the conservation status of this palm, we visited 15 populations, growing under different degrees of human disturbance in both the lowlands and the lower Andean slopes. We collected leaf material for...

The vegetable ivory palms (Phytelepheae) form a small group of Neotropical palms whose phylogenetic relationships are not fully understood. Three genera and eight species are currently recognized; however, it has been suggested that Phytelephas macrocarpa could include the species Phytelephas seemannii and Phytelephas schottii because of supposed p...

Research and conservation of palm species relies on training new generations of palm biologists, especially in tropical countries. Such trainings pave the way to answer new questions related to palm biology, sustainable management, the cultural and economic links between humans and palms, and build conservation strategies through education and civi...
