Refining reproductive parameters for modelling sustainability and extinction in hunted primate populations in the Amazon.

Primates are frequently hunted in Amazonia. Assessing the sustainability of hunting is essential to conservation planning. The most-used sustainability model, the 'Production Model', and more recent spatial models, rely on basic reproductive parameters for accuracy. These parameters are of...
