RESEARCH
INTERESTS:
My current doctoral research investigates the population dynamics
of two flycatcher species (Myiarchus
magnirostris
and Pyrocephalus
rubinus)
to understand their colonization history, diversification and disease
ecology on the Galápagos Islands. I am using molecular markers,
songs and morphological characters to compare the populations among
islands and with their closest relatives on the continent.
I started working with population genetics of Hymenopteran parasitoids
during my undergraduate courses in Brazil. However, since Ornithology
has always been a passion of mine, I changed my study taxon to Passerine
birds when I started my Masters at the LBEM.
My master’s research focused on the effects of historical and anthropogenic
fragmentation on the genetic diversity of Conopophaga
lineata
(Passeriformes: Conopophagidae) populations. I worked with populations
from Atlantic Forest fragments in Minas Gerais state, southeastern
Brazil. My results proposed that the anthropogenic fragmentation
process in this area occurred too recently (150 years ago) to be
detected on a molecular level, but instead, historical processes
had an important role in shaping the actual distribution of the
genetic variability of this species. By establishing collaborations
with other graduate students in Brazil, I started to investigate
this processes within a wider distribution range and also for other
endemic passerine species in the Atlantic Forest. These projects
are still ongoing and we have been detecting congruent historical
events for different species, but each species demonstrates unique
present population dynamics. I also participated on a Barcoding
project
under the supervision of Dr. Fabrício Santos generating barcodes
for Thamnophilidae, Pipridae and Tyrannidae species from Brazil.
