Ecological Resilience in a Primate Community Affected by Gold Mining in Suriname
Biotropica, Volume 57, Issue 2, March 2025.Over a 20‐year period of artisanal gold mining in Brownsberg Nature Park, Suriname, we documented relative stability in primate encounter rates, a shift in the location of encounters for some species and a declining trend in group sizes. We view these findings as evidence for primate resiliency tempered with concerns about smaller group sizes ...
