Influence of habitat fragmentation and host dispersal abilities on host population genetic structures and on virus prevalence in several neotropical bat species

In my PhD thesis I am particularly interested in how anthropogenic landscape modification influences bat diversity, changes virus prevalence and alters transmission in bat-virus systems. My research focuses on the population genetic structure of six phyllostomid bat species (Artibeus jamaicensis, Dermanura watsoni, Carollia perspicillata, Glossophaga soricina, Uroderma bilobatum, Trachops cirrhosus) and, therefore, their current and future distribution. I will use individual genetic data to estimate dispersal rates, population genetic structure and effective population size.
Knowledge about the population genetic patterns of organisms that are host to infectious diseases is important to make assumptions about transmission of parasites and diseases. Emerging infectious diseases in humans are increasingly traced to a wildlife origin and dispersal routes may be important pathways for transmission of these pathogens. This knowledge will allow appropriate management for conservation and the prevention of disease spread and virus transmission.
