Conservation implications of commercial hunting of black and spectacled caiman in the Mamirauá Sustainable Development Reserve, Brazil
TL;DR: In the Mamiraua sustainable development reserve in the western Brazilian Amazon, illegal hunting of black and spectacled caiman is widespread Peres and Carkeek, 1993 as mentioned in this paper.

Feeding Behavior of Two Sympatric Caiman Species, Melanosuchus niger and Caiman crocodilus, in the Brazilian Amazon
TL;DR: It is found that water temperature had a negative effect on trapping by M. niger; and water depth did not affect feeding behaviors in either species; and there is probably little interspecific competition for food during the dry season.

TL;DR: Growth rates of Melanosuchus niger and Caiman crocodilus coexisting in two areas of the Brazilian Amazon with very different environmental characteristics indicate large differences among sites, but little evidence that these differences are primarily due to differences in productivity or temperature.
