Field Sites

The work in the Lane-deGraaf lab takes place in two different, yet surprisingly similar, systems - Bali, Indonesia, and St. Louis, MO, USA. In both of these systems, we look to the anthropogenically-shaped landscape to understand the spatial and population genetics of mammalian hosts and their parasites.

St. Louis, MO, USA

In the city of St. Louis, MO, we work with the North American raccoon (Procyon lotor) and their gastrointestinal parasites, including specifically the raccoon roundworm, Baylisascaris procyonis. Our work spans the city and looks for patterns within and between raccoon populations across the Delmar Divide.

Bali, Indonesia

On the island of Bali, Indonesia, we work with long-tailed macaques (Macaca fascicularis) and their gastrointestinal parasites. Bali is one of more than 15,000 Indonesian islands, with Wallace's Line running directly between it and its nearest neighbor, Lombok. Bali sits amidst one of the most biologically diverse archipelagos in the world.
