Effect of carcass storage condition on searcher efficiency trials for conservation detection dogs

The Journal of Wildlife Management, EarlyView.
We investigated the influence of storage condition on bat carcass odor through chemical analysis. Additionally, we tested the detectability of 3 carcass storage conditions through searcher efficiency trials with conservation detection dogs. Only 20% of the chemicals observed were shared across all 4 carcass storage conditions.
