#85 Elizabeth and the Blood Feeding Network (Mexico)

How do you find out which animals a mosquito has been biting? You start by thinking like one. In this episode, biologist Elizabeth Linares Alcántara takes us to a public park in Mérida, Mexico, where she hunts blood-fed mosquitoes in their hiding spots and reads the DNA in their tiny abdomens to reveal who they have been feeding on, from humans and iguanas to feral cats and a neighbour's grazing goat.

The result is a "blood feeding network" that helps anticipate outbreaks of dengue and other emerging diseases. Elizabeth also shares a finding that turns intuition on its head, and offers a preview of next year's WDA conference, hosted in her own backyard on the Yucatán Peninsula.
