|Gillespie at work in Uganda|
Mongabay: What's the next big thing in forest conservation? What approaches or ideas are emerging or have recently emerged? What will be the catalyst for the next big breakthrough?
Thomas Gillespie: In the past decade, technological advances in non-invasive pathogen surveillance have allowed us to make great strides in understanding how infectious diseases may threaten endangered species (i.e., fecal assays to examine respiratory pathogens and blood-borne pathogens like malaria and immunodeficiency viruses). Similarly, an exciting innovation that's just taking off is letting mosquitos, leeches, and carrion flies do the work for us! All of these invertebrates seek out wildlife for a meal. By trapping them and analyzing their gut contents, we can determine which wildlife species they fed on, and in some cases, the pathogens that infected those individuals. This is especially interesting in regards to carrion flies, since they feed more or less indiscriminately on dead or dying animals. As a result, screening large numbers of carrion flies in a selected tropical forests could provide an inventory of faunal and pathogen diversity including data on the presence or absence of cryptic species. In addition, this method may alert wildlife managers to major mortality events (i.e., based on anomalies in the frequency and amount of DNA from a specific vertebrate species being recovered).
