![]() ![]() This makes the occurrence and distribution of nesting-sites unpredictable using Landsat images. crocodilus is a generalist species, able to nest hundreds of meters inside the forest far from permanent water. This behavior facilitates the identification of suitable nesting sites using moderate-resolution remote-sensing tools and should guide monitoring efforts and the protection of these areas. niger nests mainly on the shores of stable, temporally impounded floodplain lakes isolated from the early stages of the annual rising water of main rivers. Our results indicate that there is little evidence that hunting pressure shapes nest-site use of these species in our study areas. crocodilus reflects environmental constraints or is a result of hunting pressure. Ground nest surveys combined with satellite imagery allowed us to evaluate whether nest-site use by M. The heterogeneous spatial distribution of Melanosuchus niger and Caiman crocodilus in Amazonia has been suggested to reflect past hunting pressure, often underestimating the natural ecological peculiarities of these species. ![]() Nest distributions shed light on habitat use by breeding populations, which might be used as a basis for monitoring and management. Management of crocodilians is often based on source-sink dynamics, protecting breeding habitat and concentrating hunting in other areas. ![]()
