What are the two recognized subspecies of the Emperor Tamarin mentioned in conservation notes?

S. i. imperator and S. i. subgrisescens

For detailed ecological studies and targeted conservation initiatives, differentiating between the recognized variations within a species is crucial because their specific ranges may not perfectly align. The Emperor Tamarin has two formally recognized subspecies whose geographical distributions show only partial overlap within the overall habitat range. These two distinct subspecies are designated as *S. i. imperator* and *S. i. subgrisescens*. Knowing which specific subspecies inhabits a particular parcel of threatened rainforest can help conservationists tailor support efforts more effectively, acknowledging that localized threats might disproportionately affect one group over the other depending on their precise location within Peru, Bolivia, or Brazil.
