Arboreal mammal richness on fluvial islands and continuous floodplain forests of Middle-Solimões River region in Central Amazon

These data are a product of Rafael Rabelo’s Master thesis, conducted at the Ecology Graduate Program of Brazil´s National Institute for Amazon Research (INPA), with logistical and financial support from Mamirauá Institute for Sustainable Development (IDSM-OS/MCTIC). The main objective of the research was to test the 'habitat amount hypothesis', which predicts that the effect of patch size on number of species results from a 'sample area effect' rather than an 'island effect'. Additionally, the separated the effects of island size and of landscape-scale habitat amount on species richness were evaluated.
