Biology, PhD in Ecology

My area of interest es in plant Ecology and animal-plant interactions. I have developed skills in data analysis in several projects incluiding biodiversity studies (specially avian communities), seed germination, seed dispersal and granivory. I have advised more than 20 projects and thesis, using several statistic pakages, incluiding R environment and SPSS.

Pollen flow in Palicourea fendleri : an experimental test of the Disassortative Pollen Hypothesis

Oecologia
The Disassortative Pollen Flow Hypothesis proposed by Darwin postulates that the relative position of anthers and stigmas in distylous flowers enhances pollen flow between flowers of different morphs (legit- imate pollination). In our experimental system, the probability that the pollinator extracts a pollen grain from the anther and the probability of self-pollination were both dependent on the type of floral morph

Gene Flow Between Natural and Domestic Populations of Lutzomyia longipalpis (Diptera: Psychodidae)

Journal of medical entomology
The epidemiology ofthe visceral leishmaniasis in the Americas is associated with both a natural and a domestic cycle. Th This species has high migration rates between domestic and natural environments, and has the potential to transport for Leishmania from natural to domestic environments

Granivory, seed dynamics and suitability of the seed-dish technique for granivory estimations

Journal ofTropical Ecology
Spatial and seasonal patterns of seed removal by rodents, ants and birds were evaluated using seed-dish experiments in a savanna. Rodents were the major seed predators in all the habitats, except for the savanna/forest border where birds dominated. Ants removed more seeds than birds, but since they preferred the smallest seeds, ants ranked last in mass removed.

Ecology and Biogeography of Arbuscular Mycorrhizal in the Guayana Shield), Venezuela

Springer Nature
Arbuscular mycorrhizal fungi (AMF) play a crucial role in ecosystem functioning by improving plant nutrition and resistance to environmental stress. In this work, some ecological and historical factors possibly involved with the restricted distribution of these species. Their endemism could be the result of a process of in situ diversification combined with limitations for dispersal and/ or establishment. These findings allows proposing LGS as an evolutionary hotspot for Gigasporaceae.

PATTERNS OF HABITAT USE BY BIRDS ON A WELL-DRAINED SAVANNA OF OF THE EASTERN VENEZUELAN LLANOS

Ecotropicos
We studied habitat use by the avian community during dry and rainy seasons, in a region of well-drained savannahs on the Eastern Llanos, in Venezuela. We obtained a list of 173 bird species for this area. . We found evidence of population movements between habitats. The largest movement was observed between savannahs and low-lands. We detected important interactions among bird communities of the three habitats; these three habitats have a large effect in the diversity of birds.
