Marajó, located in the lower Amazon, Brazil, is one of the largest river islands in the world. Most of the island is subject to tidal or seasonal flooding. Despite its historical, cultural and geographical importance, Marajó Island remains relatively less investigated in terms of mammal diversity, ecology and community structure than the rest of the Amazon. This scenario has motivated the presentation of this list of land mammals of eastern Marajó Island. Two field surveys were conducted in the course of 7-11 December 2012 and 17-25 October 2013 in Jaranduba, Dunas and Ribanceira Farms, northeast portions of Marajó Island. A total of 23 large and medium-sized land mammal species were recorded in the study area. These farms host a representative mammal community of northeastern Marajó, an area lacking previous faunal studies. Human pressure over centuries has deeply modified the environment in Marajó. Therefore, striking evidence of a long human-populated past in this island is in accordance to many other sites throughout the Amazon plain. The result of a land mammal survey in northeastern Marajó is a clear evidence of past and present human interference in the island. Even though Marajó Island has exalted mammal diversity, it will be much higher if long-term studies are effectively implemented.
