Influence of diet overlap and nest-site aggression on human–black caiman conflict in Guyana

Abstract

The black caiman (Melanosuchus niger) is the largest aquatic predator in the Amazon freshwater bioregion. Their destruction of fishing gear, consumption of fish and turtles, and infrequent attacks on humans, pets, and livestock are drivers of conflict with riverine communities. Attitudes toward black caiman can motivate negative human–caiman interactions across their range. In this article, we explored the importance of understanding attitudes toward the presence of black caiman populations. We surveyed four villages situated along the Rupununi River in the North Rupununi Guyana. Analysis indicated that negative attitudes were influenced by seasonality, sex, and village. Results offered additional insights into human–wildlife interactions and the dynamics of living alongside a protected large predator in Guyana. We recommend further research into the linkage between black caiman behavioral ecology and incidences of conflict.
