My research is focused in studying the morphology and DNA of arachnids to unveil their diversity, systematics and biogeography. Within the arachnids, the study groups I work with are Amblypygi (whip spiders or tailless whip scorpions), Schizomida (shorttailed whipscorpion), Thelyphonida (whip scorpions or vinegaroons), Palpigradi (microwhip scorpion), Araneae (spiders) and Opiliones (harvestmen).
- Phylogeography of the Atlantic Forest using whip spiders as a model organism
This project aims to use next generation sequencing methods and a multi-locus approach to analyze the genome of an invertebrate group, the whip spiders of the genus Charinus. Expanding on the work done for my doctoral thesis, the plan is to collect fresh material from 20 points in the Atlantic Forest, from the northernmost to the southern region of the forest, extract, amplify and sequence the DNA, and analyze the population genetics of the species sampled. With this fine-scale approach to the forest diversity, it will be possible to model species distributions, understand past effects of tectonic events and climatic changes in the forest's Charinus fauna, and predict the effects of future climate changes in this hyper diverse forest. This will be one of the first phylogeographies of the AF using an invertebrate as a model, the first phylogeography using genomic data. This research is an important step towards understanding South American biodiversity, and the broad question of why some areas of the planet harbor a greater degree of diversity than others.
- Systematics, taxonomy and biogeography of Amblypygi
The Amblypygi is an amazing group of organisms that has much of its taxonomy and systematics unresolved. This project has the aim of addressing questions relating to evolution of these animals, their conservation and relationship. To reach that, I use morphology and DNA (multilocus data [the usual suspects] and Ultraconserved Elements [UCE]). To explore the historical and ecological biogeography of the group, I date calibrate molecular trees (using BEAST), do ancestral state reconstruction (with BioGeoBEARS), and study species limits and genetic diversity (population genetics and phylogeography using a pipeline for SNPs from UCE data).
- Systematics and taxonomy of Schizomida
The poorly known arachnids order Schizomida has its diversity underestimated, a possible result of its cryptic habitat, small size and lack of taxonomic studies. This project is trying to resolve the order's taxonomy and phylogeny with the description of new species and raising of new characters for a morphological and molecular phylogeny of the group.
