I’m interested in the classic question of “why are some groups so species rich while others are so poor?” but focusing on the species-poor group point of view, which are the exceptions to the rule in Amazon freshwaters. I am studying the Sailfin Tetra (Crenuchus splilurus), a sexually dimorphic species that is widespread in Amazon. The rationale of my work hinges on the complex geological past of the Amazon, which created many opportunities for allopatric speciation and is pivotal to explain the high diversity of small size freshwater fish species we see today. This landscape dynamics helps explaining the high diversity of most groups, but it also raises the question of why some species are widespread and phenotypically similar. I’m combining phylogeography, local abiotic pressures and behavior to understand this complex system.

My home institution is the National Institute for Amazonian Research (INPA) (located in Manaus, Brazil), where we recently assembled a laboratory for conducting behavioral trials. I also collaborate on community ecology studies. My past experience includes watching fish doing nothing in the intertidal zone and trying to sort out very similar-looking fish from the Madeira River.
