Jaguar local extinction consequences for medium and large-sized terrestrial mammals populations in the Atlantic Forest.

Roberta Montanheiro Paolino, MSc

Doctoral research: 

  • SummarySpecies extinctions result in consequences for ecosystems such as trophic chain effects. The absence of a top predator may increase pray and mesopredators populations, which change ecological process such as herbivory, dispersion and seed predation. Therefore, we aim to analyze jaguar (Panthera onca) local extinction consequences comparing the medium and large-sized terrestrial mammals community in two protected areas, one that has an intact trophic chain (Parque Estadual de Carlos Botelho) and other where the jaguar is probably extinct (Parque Estadual da Serra do Mar - Núcleo Santa Virgínia base Vargem Grande). We will estimate richness, beta diversity, species occupancy, detection, density and abundance in each area with camera-trapping data. We will also assess co-occurrence patterns to analyze the effect of jaguar presence. Site covariates will be incorporated in the models to assess the influence of landscape and human presence on the populations. Hunting effects and motivations will be analyzed by surveys with local residents  in order to propose mitigation and prevention actions.

Spatial prioritization in Atlantic Forest a multispecies approach (Pantera onca and Puma concolor)

Yuri Ribeiro

Undergraduate project: 

  • SummaryThe main objective of this project is to identify priority sites for both jaguars and cougars conservation in Atlantic Forest. Other objectives of this research are: to apply a conservation prioritization analysis (Zonation algorithm); to generate thematic maps, showing areas identified as priorities for the species conservation. This research results will be a useful source of information for stakeholders and decision makers in order to define conservation priorities for both species.

Landscape genetics, viability, and spatial ecology of a puma population (Puma concolor) in a highly human modified landscape.

Renata Alonso Miotto, PhD

Pos-doctoral research: 

  • SummaryBy using different tools, such as molecular markers and GPS collars data, we aim to understand how this top predator still occupy severely modified areas and which landscape features most influence its genetic structure and genetic diversity distribution.

Structure of bird assemblages and its relation with landscape metrics and ecosystem services provisioning in secondary forests.


Post-doctoral project: 

  • SummaryThis study aim to comprehend how the structure (functional richness, functional evenness and functional divergence) of bird assemblages in secondary forests respond to landscape measures potentially related to ecosystem services provisioning, and to the structural complexity of vegetation, such these informations can give support to restoration, management and conservation actions in anthropic landscapes.
