The Devil's in the Diversity: Divergent Parasite Faunas and their Impacts on Body Condition in Two Greenland Caribou Populations
Parasites are important components of ecosystems; significantly impacting host health, and informing on contemporary and historical host movements and environmental changes. I characterised gastrointestinal parasite faunas and assessed their associations to body condition and fecundity in two popula...

Parasites are important components of ecosystems; significantly impacting host health, and informing on contemporary and historical host movements and environmental changes.
