Ph.D. research
“The evolution and systematics of the Cycnoches orchids”

Orchids have always captured the imagination of biologists, naturalists, amateurs and lay people from around the world, due to their remarkable display of floral morphologies and reproductive strategies. With about 800 genera and 26,000 species distributed worldwide, Orchidaceae is one of the largest families of flowering plants. Orchids are also of key economic importance in many corners of the world because of their top priced horticultural varieties and their industrial applications, as is the case of the vanilla orchid. Charles Darwin, a professed orchid lover, stands as one of the major researchers in orchid pollination biology. In 1862, he studied sexual systems and the impact of self-pollination in orchids and he termed members of the subtribe Catasetinae “the most remarkable of all Orchids” (Darwin 1862, chapter VI). Darwin was bewildered with members of this charismatic Neotropical lineage because of their amazing array morphological diversity, pollination syndromes, such sexual deceit, oil and fragrance reward, and reproductive strategies.
My dissertation project deals with the evolution of the subtribe Catasetinae (Cymbidieae), with special emphasis on the sexually dimorphic genus Cycnoches. Using a wide range of phylogenetic analysis, I aim to reconstruct the evolutionary relationships within the subtribe. Based on a solid phylogenetic framework, I am interested on study the evolution of sexual systems in Catasetinae and investigate different geographic, biological and climatic factors that have shaped clade evolution between this remarkable lineage.

Other research interests

Orchid taxonomy

I am also interested on the taxonomy of various neotropical orchid lineages such as those belonging to the subtribes Epidendrinae (Epidendrum L.) and Pleurothallidinae (Acianthera Schw., Lepanthes Sw.). This part of my research work involves active fieldwork, focused on the endangered and poorly studied cloud forests of Colombia. Explorations carried out during several years (2008-2012) have resulted on the enrichment of local herbaria collections (VALLE, CUVC – Colombia).

Species delimitation using Next Generation Sequencing and Fragrance profiles on orchid species complexes

Using SNIP data generated by GBS technique and fragrance profiles analyzed using Gas Chromatography-Mass Spectrophotometry; we aim to bring light into the intricate relationships of several variable species from the orchid genus Cycnoches. Such species are clustered into two complexes, named C. egertonianum and C. guttulatum complexes. The former encompasses species distributed from Costa Rica to Southern Mexico, whereas the latter includes species growing in Panama and possibly in the Choco Biogeographic Colombian region. Preliminary results have shown that, individuals formerly assigned to different species (e.g. C. guttulatum, C. dianae and C. pachydactylon), might in fact by a single, quite variable specie: they share the same pollinator and fragrance profiles are very similar.
