The distribution of Caiman crocodilus crocodilus and Caiman yacare populations in Brazil
The distribution and relationships among populations of Caiman crocodilus crocodilus and Caiman yacare were investigated throughout Brazil. Caiman c. crocodilus inhabits the drainages of the Rio Solimoes/Rio Amazonas, Araguaia, Araguari, Itapicuru, Paranaiba, Negro, Tapajos, Tocantins, Xingu, and th...

The distribution and relationships among populations of Caiman crocodilus crocodilus and Caiman yacare were investigated throughout Brazil. Caiman c. crocodilus inhabits the drainages of the Rio Solimoes/Rio Amazonas, Araguaia, Araguari, Itapicuru, Paranaiba, Negro, Tapajos, Tocantins, Xingu, and the rivers draining to the Atlantic Ocean on the northern coast of Brazil. It does not occur in the Rio Sao Francisco. Caiman yacare is endemic to the Rio Mamore, Rio Guapore, Rio Paraguai and Rio Parana river systems and all of their lowland drainages. The northernmost limit for C. yacare lies between Costa Marques (12°25′S, 64°10′W) and Guajara Mirim, Pacaas Novos on the Rio Mamore (10°55′S, 65°15′W). Small populations of apparently hybrid individuals were observed in the upper Rio Acre, the Rio Abuna, the upper Rio Madeira, and the Rio Mamore between Guajara Mirim and Abuna. Caiman c. crocodilus and C. yacare populations are geologically separated and morphologically distinct. The taxonomic recognition of Caiman species with overlapping distributions in the states of Mato Grosso and Mato Grosso do Sul appears to be without merit. |
