Hi there! I am a doctoral student in the Graduate Program of Ecology, at Federal University of Pará state, Amazon, Brazil. My research areas include ecology of communities, influence of environmental modifications on the natural communities of aquatic invertebrates in small Amazonian streams. Since my undergrad in 2014 I’ve been working with the research team of the Laboratory of Ecology and Conservation (LABECO), studying how human activities influence the aquatic fauna of streams, one of the most important and threatened freshwater systems in Brazilian Amazon. My undergrad monograph tried to understand the role played by mining activities on communities of damselflies (Odonata order) in streams of Pará state. Afterwards, in my masters, I studied the ecological relationship between dragonflies (Odonata order) and aquatic macrophytes in big freshwater systems in a national forest, also in Pará state. Finally, in my doctoral degree I’m using a huge dataset, composed by environmental, spatial, compositional and morphological information of dragonflies and damselflies sampled in the Brazilian Amazon. The main purpose of my doctoral thesis is to unveil 1) the importance of sustainable use areas for the conservation of biodiversity; 2) the influence of regional and local drivers for both dragonflies and damselflies; and 3) the importance of specific morphological traits, used as dispersal proxies, for the latitudinal ranges of both groups. The main rewards of my research are 1) going to the forests and facing great adventure along the trails; 2) using this astonishing computational tool called R, the most amazing invention in the history of humankind; 3) studying such incredible groups such as dragonflies and damselflies, fantastic bioindicators of the environment health; and much more. So, when I’m not on R, identifying dragonflies and damselflies, or writing my papers, for sure I’m reading (or re-reading) a book, studying English or French (or another language), watching some TV show or movie, or, maybe, going through my workout routine.
