Moose Survival and Habitat‐Associated Risk of Endoparasites
Ecology and Evolution, Volume 15, Issue 12, December 2025.We observed high rates of adult and calf moose survival in New York State, with mortality primarily due to disease associated with giant liver fluke infections. Calf mortality risk increased with increasing use of wetlands, where they can acquire giant liver fluke infections, and decreased with higher amounts of nutritional energy available.
