Protected areas in tropical countries are managed under different governance regimes, the relative effectiveness of which in avoiding deforestation has been the subject of recent debates. Participants in these debates answer appeals for more strict protection with the argument that sustainable use areas and indigenous lands can balance deforestation(More)
Indigenous people of the Rupununi region of Amazonian Guyana interact with their natural environment through hunting and subsistence agriculture. To date the sustainability of indigenous livelihoods has been analyzed by modeling either hunting or forest clearing. Here we develop a holistic model framework with agent-based modeling to examine interactions(More)
Conservation of Neotropical game species must take into account the livelihood and food security needs of local human populations. Hunting management decisions should therefore rely on abundance and distribution data that are as representative as possible of true population sizes and dynamics. We simultaneously applied a commonly used encounter-based method(More)
Citizen scientists’ important contributions to biodiversity conservation are constrained by their focus on data collection and public outreach in wealthy, accessible places. Sustainable conservation actions require initiatives such as those supported by the Participatory Monitoring and Management Partnership (, in which data collected(More)
Using data from a three-year study of socioeconomic factors influencing hunting in 23 indigenous communities, we assess the influence of indigenous and Christian beliefs and practices on dietary taboos among Makushi and Wapishana peoples in the Guyanese Amazon. We found that members of Evangelical and established (Anglican and Catholic) churches do not(More)
Biodiversity affects many ecosystem functions and services, including carbon cycling and retention. While it is known that the efficiency of carbon capture and biomass production by ecological communities increases with species diversity, the role of vertebrate animals in the carbon cycle remains undocumented. Here, we use an extensive dataset collected in(More)
