Introduction
I am interested in the study of genetic diversity and population structure in plants and to what extent these are influenced by the life-history and reproductive traits of the species. I am also interested in the application of morphological and molecular data to plant taxonomy and phylogenetics.

Cuantificación de la diversidad morfológica y genética y filogeografía de la hepática acuática amenazada Riella helicophylla como herramientas para su conservación.

The genus Erica is the epitome of fynbos biodiversity and both species richness and endemism in this genus are markedly associated to the fire-sensitive, post-fire-recruiting (i.e. seeder) life-form. By using microsatellite markers, Segarra-Moragues and Ojeda (2010) investigated the genetic background of seeder and resprouter (fire-resistant) populations of the fynbos species Erica coccinea and found higher within-population genetic diversity and higher among-population differentiation in seeder populations. Apart from the regeneration polymorphism of E. coccinea (i.e. distinct seeder and resprouter individuals) this species is characterized by a conspicuous variation in flower size and colour. Most populations are colour-monomorphic, although there are some colour-dimorphic populations, including red-flowered and yellow-flowered plants. A strong association between flower colour and regeneration form has been highlighted in E. coccinea: seeder plants being mostly yellow-flowered and resprouter plants being mostly red-flowered. Red-flowered plants in E. coccinea are anthocyanin producers (A+), whereas yellow-flowered plants are unable of biosynthesize anthocyanins (A-). Both red and yellow flowers in this species are indistinctly visited by the orange-breasted sunbird (Anthobaphes violacea), which seems to be the only pollinator of this species. Thus, what is driving flower colour polymorphism in E. coccinea? To answer this question, I am using both floral biology (in collaboration with Jeremy Midgley) and metabolomics approaches (in collaboration with Riitta Julkunen-Tiitto's lab).
