“…On the Brazilian side of the boundary lies the Serra do Divisor National Park, and on the Peruvian side its transboundary sister reserve, the Sierra del Divisor National Park. The adjacent transnational parks are part one of the largest contiguous blocks of protected areas in the Amazon, but despite their protected status, the region is threatened by anthropogenic activities including agriculture, hunting and subsistence fishing, tourism, and plant extraction for timber, charcoal, firewood, and horticulture (Associação SOS Amazônia 1998;Daly et al 2016;Esteves & Luz 2019). The location surveyed in this study, selected as the type locality, is protected within the Serra do Divisor National Park (SDNP), whereas the other known locality occurs outside of the park boundaries in an area that has been actively deforested in the last 40 years and where habitat transformation and deforestation continue unabated.…”
