Bachelor's degree in Biological Sciences at the University of São Paulo (2002/2003). Master in Ecology at the National Institute of Amazonian Research - INPA (2006) and Ph.D. in Botany at the Institute of Biosciences - USP (2011). I offered classes of botany and evolutionary biology at the Federal University of São Carlos (campus Sorocaba) during a year, from August 2011 to June 2012. I'm currently developing a post-doctoral project at the Institute of Biosciences - USP (FAPESP process 2012/02110-5; http://www.bv.fapesp.br/pt/bolsas/133325/evolucao-dos-nectarios-extraflorais-herdabilidade-selecao-natural-e-especializacao-das-interacoes-fo/). The duration of the pos-doc project is from May/2012 to December/2014, entitled - Evolution of extrafloral nectaries: heritability, natural selection and specialization of ant-plant interactions. I have field experience in ecology and botany including natural areas of rainforests (e.g. Amazon forest) and savannas (e.g. Cerrado). My actual research is focused on questions related to (1) distribution patterns of plants, and (2) trait evolution associated with different aspects of plant-animal interactions. I'm really interested in planning projects with evolutionary biology integrating observational and experimental approaches, considering the evolutionary process on the scale of populations, and the macro-evolutionary pattern among species.

This project investigates floral variation in the genus Chamaecrista, focusing on two complementary dimensions: resource allocation and micromorphological diversification. The first phase analyzes the allometric relationships between total floral mass and biomass allocation to the male (androecium) and female (gynoecium) reproductive organs. The central hypothesis is that larger, more pol…
Nitrogen (N) is essential for life, with atmospheric N2 being converted into ammonia by root-nodulating bacteria in a process called biological nitrogen fixation (BNF), primarily associated with legumes. This nutrition mutualism occurs in belowground root nodules, enhancing the ecosystem's nitrogen availability and crop growth. However, the outcome of plant-rhizobia mutualisms varies spat…
In the last decades, we have experienced a large increase in the research interest in mutualistic interactions. Mutualism is now best viewed as reciprocal exploitation in which the benefits often outweigh the associated costs of interactions, with the net benefit varying as a function of biotic and abiotic factors that directly or indirectly modify costs and benefits. Although variable, t…

The visit of Prof. Ítalo Coutinho aims to deepen the study of the anatomy and function of extrafloral nectaries (EFNs) in Chamaecrista (Fabaceae). As a specialist in secretory structures and vegetation of dry areas, he will contribute to integrating morphoanatomical data with water transport and nectar secretion, clarifying how EFN vascularization influences their function and environment…
The ecological heterogeneity of tropical ecosystems is related to the high diversity of plant species. The growth and survival of these species depend on morphological and functional traits, such as wood anatomy and water transport capacity. In this project we will investigate how the vascular structure of the xylem is related to the hydraulic functions along of climatic gradient, especia…
Plantas e rizóbios são parceiros em mutualismos nutricionais que evoluíram diversas vezes, inclusive entre leguminosas. A estabilidade desse mutualismo em leguminosas está ligada à formação de nódulos radiculares. A formação e proliferação dos nódulos pode ser reduzida sob certas condições ambientais e depende dos parceiros envolvidos, afetando a eficiência da fixação de nitrogênio e outr…
The nutritional mutualism between plants and nitrogen-fixing bacteria is an evolutionary response to the nitrogen (N) limitations that constrain restoration efforts and agriculture. Some legumes maintain a nutritional mutualism with N-fixing rhizobia via specialized plant organs, the nodules, whose formation depends on a gene network. These nodulation genes probably evolved in an ancestra…
Mutualisms play a pivotal role in shaping ecosystems, exerting profound effects on plant fitness and community dynamics. This project seeks to explore the mutualistic relationships between legumes, particularly Chamaecrista species, and their symbiotic microorganisms, with a focus on rhizobial and non-rhizobial bacteria, as well as arbuscular mycorrhizal fungi (AMF).The primary objective …

The outcome of mutualisms can vary depending on the quantity and quality of services and resources exchanged between species. In pollination, pollinators are attracted by flower signals associated with resources such as nectar and pollen. When the signal and the resource are correlated, we consider the system honest to pollinators due to the phenotypic coupling of both. In species with po…
Esta bolsa técnica visa o processamento, tratamento, organização, e divulgação dos dados gerados pelo projeto Synergistic effect of multiple mutualists on plants: how bacteria, ants and bees contribute to the evolution of a hyper-diverse lineage of legumes. Primeiramente, será realizado o processamento e tratamento de dados experimentais e observacionais de mais de 100 espécies de Chamaec…

Life History Theory explores how organisms allocate limited resources between growth and reproduction, leading to distinct short and long-life cycles. In angiosperms, these strategies correlate with floral traits and reproductive system. Short-lived species tend toward self-pollination, with smaller, less resourced flowers, while long-lived species are often cross-pollinated and invest mo…
Plants obtain energy through photosynthesis, distributing non-structural carbohydrates (NSC) to various organs throughout the day, with some resources allocated to maintaining mutualistic relationships with other species. However, the influence of carbohydrate availability in these tissues on the balance of such interactions remains underexplored. The restriction of soil water availabilit…
The main aim of this project is consolidate ecological and evolutionary studies of ant-plant-herbivores interactions in the tribe Bignonieae (Bignoniaceae). During the six months in the Universidad de Jaén, we expect to: (1) test the ecological network structure of ant-plant interactions and the degree of specialization of these interactions in an Amazonian forest community, in conjunctio…
