Here are my research projects:

The value of forest corridors to the conservation of birds in an Atlantic forest fragmented landscape (master thesis)

This project is divided in two approaches: movement behavior of an understory bird species at the individual level; and bird community responses to corridor width and type (riparian or non-riparian).

How wide forest corridors should be to maintain Atlantic forest birds? I evaluated how patterns of forest bird richness and composition are affected by corridor width. I found that narrow corridors (< 100 m wide) are much less effective in conserving Atlantic forest birds. This result have direct  consequences on the discussions about modifications in the Brazilian Forest Code. Here is a link to a press note about this study (in Portuguese).

Do corridors increase interpatch movements? I am using an empirical approach with a rainforest bird to address this question. Using translocations associated to radio-tracking I am studying if corridors enhance movements of the White-shouldered Fire-eye (Pyriglena leucoptera) in fragmented landscapes.

The white-shouldered fire-eye (Pyriglena leucoptera,  Thamnophilidae, Passeriformes) is an understory insectivorous bird endemic to the  Atlantic forest. It is negativelly affected by deforestation in the Atlantic plateau of the state of São Paulo. Are fire-eyes able to use forest corridors to move through fragmented landscapes ? Or, more importantly, do fire-eyes manage to move in the absence of corridors? These are questions I tried to answer in my Master Thesis.

Movement behavior of an endemic woodcreeper in Atlantic forest fragmented landscapes

In this research my colleagues and I evaluated the effects of open fields and isolated trees (stepping-stones) on the movement behavior of the Lesser woodcreeper  (Xiphorhynchus fuscus), an Atlantic forest endemic bird. Using experimental translocations coupled with radio-telemetry we compared the homing behavior of the species in forest patches separated by increasing distances from each other and with or without stepping-stones. The results of this research were published in Biotropica.


Ecology and distribution of the critically endangered Cone-billed Tanager
Conothraupis mesoleuca

For three years I have been mapping the distribution of the critically endangered Cone-billed Tanager in the state of Mato Grosso, western Brazil, as well as conducting a habitat selection study. Using playback trials I compared avaliable vs. used habitats, being able to infer if different habitat types available in the region are preferred or not by the species. Partial results of these study were published in Bird Conservation International.
