Research focus<\/h4>\n

Historical climatic fluctuations, biogeographic barriers, and landscape dynamics have shaped the diversification and distribution of many South American forest plant lineages. Tree ferns, primarily associated with humid forest domains, provide an ideal system to investigate how evolutionary processes, geographic isolation, and demographic history interact across large spatial scales. At the same time, several species within this group are increasingly affected by anthropogenic pressures.
\nMy PhD project investigates the population structure, species delimitation, and historical connectivity of South American tree ferns, with a focus on Dicksonia and Lophosoria (Dicksoniaceae) across Brazil, Bolivia, and Chile. The project integrates systematics, biogeography, and population genetics to clarify taxonomic boundaries and reconstruct patterns of historical and contemporary connectivity among populations. By assessing genetic diversity, population differentiation, and gene flow across the species\u2019 ranges, the research aims to identify distinct evolutionary lineages and characterize patterns of genetic structure. These insights also inform conservation assessments, particularly for Dicksonia sellowiana, currently classified as Endangered (EN) on the Brazilian Red List due to habitat loss and past overexploitation for ornamental and horticultural purposes.<\/p>\n
