Found in patches, preferentially in more shaded habitats, near watercourses.
It is possible that the two seasonal watercourses were blocked by a dam but lacked a canal system to distribute the water.
These networks were visualized by communication routes and watercourses, along which most settlements were lined up.
The reason for this exceptional sensitivity to global climate seems to be its watercourse, which includes vast swamps in the coastal plain.
These elements are the toponymic glyphs, the buildings, the watercourses, and the paths or roads.
Stream-dependent amphibians were only tested with the eight elevations where watercourses were found.
The area is extremely flat, with a difference in altitude of only a few cm per km, intersected by poorly developed watercourses.
A response to ecotones was revealed for the amphibian subset only and associated with the presence or absence of watercourses.
