Evidence

Peer-reviewed community-based wildlife health surveillance

Geography

Nunavut, Canadian Arctic

System

Barren-ground caribou and Arctic food system

## WHAT THE EVIDENCE SAYS

A community-based surveillance program working with Inuit harvesters documented visible lesions and filarial nematodes in harvested barren-ground caribou, including Setaria yehi and Onchocerca lineage 2\. The study links local observations, veterinary investigation and molecular identification to characterize syndromes that conventional wildlife-health systems could otherwise miss across a remote landscape.

## WHY IT MATTERS / OUR READ

The important result is as much about surveillance architecture as the parasites themselves. Harvesters operate across places and seasons that formal monitoring samples sparsely, so durable community partnerships can create earlier, geographically richer wildlife-health intelligence while keeping observations connected to food security and local knowledge.

## CAVEATS / UNCERTAINTY

The observations do not establish a population-wide prevalence trend or prove that climate change caused the infections. Sampling is tied to subsistence harvest rather than a randomized population survey, and the study does not quantify human food-safety risk. Climate sensitivity is a plausible ecological context, not a single demonstrated causal pathway.
