Project Cantão of Giant Otters “Molecular Ecology of Giant Otters (Pteronura brasiliensis) in Cantão State Park, Araguaia, TO”

Cantão State Park is located in an octone between Cerrado and Amazon Rainforest biomes. It is situated in the middle of Araguaia migration corredor, which connects the Pantanal of Mato Grosso with the Amazon River basin. The Park shelters an unknown population of giant otters but of great genetic relevance in the area. The objectives of this project are the following: to investigate population structure, molecular demography and signs of existing population bottleneck, as well as parenthood dynamics among the individuals of this group of giant otters.

The objectives of this project partially meet Goal 2 and actions 2.1, 2.4, 2.9 of the Giant Otter National Action Plans- NAP (ICMBio).
