Introduction
I am a post-doctoral fellow at the Spatial Ecology and Conservation Lab at UNESP, Rio Claro, São Paulo, Brazil. During the last few years, I have been studying the influences of urbanization on biodiversity and ecological processes. I am especially interested in understanding how environmental characteristics of urban landscapes, especially of the urban vegetation, affect taxonomic and functional characteristics of birds inhabiting the urban matrix. Currently I am leading a research network with the aim of assessing the effects of urbanization on predator-prey associations distributing dummy caterpillar models in all Brazilian state capitals. My research interests include ornithology, ecological modeling, spatial ecology, landscape planning and urban ecology.

Preprint
Biodiversity conservation in heterogeneous landscapes faces the challenge of accounting for the complex interactions between the variation in species responses, existence of multiple habitats, diverse governance regimes, and anthropogenic threats. Yet, the scarcity of integrative studies still limits our understanding of the combined effects of soc...
Article
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban...

The Cartesian world view established a model of development for western cities that led to a number of environmental, social, and economic consequences. In order to overcome these challenges, a reform in current thinking is necessary. Thus, this article aims to intertwine the concepts of complexity of Edgard Morin and the concepts of landscape prop...
Article
Cities are new and expanding ecosystems that harbor a variety of habitats with different degrees of permeability to the local fauna. However, the assessment of urban landscape permeability usually considers biotic and abiotic conditions, with sociopolitical dimensions (e.g., zoning regulations) – also important in shaping urban biodiversity – being...
Article
Intensification of urbanization has been shown to be associated with taxonomic and functional modifications of biological communities, leading to changes in trophic interactions. These changes may reduce the delivery of ecosystem services provided by urban ecosystems. For instance, predation on herbivorous insects is an important ecological process...

Article
Cultivated pastures occupy 30% of the Brazilian Cerrado. Most pastures have low productivity, demanding intensification. Pasture intensification, as conventionally proposed, promises conservation by land sparing. However, it does not embrace silvopastoral systems, a type of intensification that enhances carbon balance and in situ biodiversity conse...

To reduce herbivory, plants bearing extrafloral nectaries interact with ants and attract them by providing food. As plant bodyguards, ants respond to the resource provision and, using their antennae, detect chemical messages from the host plants that help them to locate herbivores. Ants can also use their vision to explore the environment; however,...

The effects of streets on biodiversity is an important aspect of urban ecology, but it has been neglected worldwide. Several vegetation attributes (e.g. street tree density and diversity) have important effects on biodiversity and ecological processes. In this study, we evaluated the influences of urban vegetation—represented by characteristics of...

Project
This project's main goal is to integrate how the structural characterization of the urban landscape affects the arthropod fauna, focusing on the role of urban green spaces to achieve sustainability in cities and contribute to the conservation of biodiversity. Thus, we have like specific goals (I) to assess how the urban density gradient affects the structure of the arthropod community; (II) to analyze the effects of green cover on pollinating insects, assessing diversity aspects and composition of these insects and what urban factors are important to maintain and ensure biodiversity and the ecosystem services provided by these organisms; (III) to survey the vector and synanthropic Diptera fauna of the continuous urban area of ​​Belém, to assist in the decision-making on mitigating measures on a fauna that negatively impacts the population human; (IV) to know the biodiversity of arboreal arthropods associated with urban vegetation so that understand how structural aspects of trees and connectivity with surrounding vegetation can restrict the diversity and abundance of these organisms; (V) to create and suggest management strategies and urban planning indicators, based on these groups of organisms for sustainable growth and development of the municipality of Belém and its municipalities neighbors, as well as finding positive aspects, identifying deficiencies, and proposing solutions.
Project
Using dummy caterpillar as models, my post-doctoral project aims to achieve two main scientific goals: (1) assess the predation risk on insect prey and predator composition within urban parks and squares and (2) assess the predation risk on insect prey in urban landscapes in a continental scale. To do this, we will adopt an ambitious approach: through a large-scale collaborative research network we will distribute dummy caterpillar models through squares and urban parks within each Brazilian state capital – totaling 27 cities – and will adopt a standardized sampling method. For the first goal, we will compare predation risk and predator composition between urban parks and squares. For the continental scale assessment, we will explore the large variability between Brazilian cities and assess the effects of the latitudinal and altitudinal gradients, the proportion of vegetation and human population on predation risk on insect prey.
Project
The objective of this project is to evaluate the impacts of the landscape structure and connectivity on the occurrence of endemic birds of the Brazilian Atlantic Forest using landscape metrics and urbanization data. We used 10 birds species: Sclerurus scansor, Xiphorhynchus fuscus, Automolus leucophthalmus, Drymophila ochropyga, Formicivora serrana, Mackenziaena leachii, Chiroxiphia caudata, Pyriglena leucoptera, Thamnophilus caerulescens and Myiothlypis leucoblephara. The study is divided into three stages: - 1: to evaluate multiple scales that influence the occurrence of these species, ranging from the landscape structure (on a macro scale) to the vegetation structure (on a micro scale). - 2: to relate the impact of urbanization on these species, evaluating the importance of urban forest fragments for the persistence of these species, as well as the need to preserve key fragments for the connectivity of the landscape. - 3: to elaborate ecological corridors using biological data of the species associated to urbanistic data.
