Hello, Bluesky! We're the IUCN SSC Parasite Specialist Group, a part of the Species Survival Commission! We're just starting to understand the important roles parasites play in their ecosystems, and our goal is to determine the threats wildlife parasites face and to conserve rare and unique species!

Co‐Infection, but Not Infection Intensity, Increases Shedding in a Gastrointestinal Helminth of Gamebirds
Host heterogeneity in disease transmission is influential in shaping disease dynamics, but its drivers remain poorly understood. Shedding intensity is often assumed to be directly proportional to inf...
