| Summary: | As in the case of human systems, biodiversity can be affected by
climate change and climate variability. The effect takes places through variations in
temperature and precipitation expressed in space, which change habitat conditions, and
determine, thereby, the distribution of species. In this sense, an analysis of climate change
impacts on the distribution of two species in the Rio Negro basin was made, specifically in
the reserve areas of the municipality of Novo Airão-Amazonas, by applying climate change
scenarios developed by the Intergovernmental Panel on Climate Change (IPCC). The
mapping was carried out for species of economic and environmental importance
in tropical forest ecosystems: Gymnotus Carapo (Sarapó) and Cichla sp. (Tucunaré);
comparing its current potential distribution with scenarios projections for 2050 and
2070, for the Representative Concentration Pathway (RCP) 8.5. This goal was achieved
by applying MaxEnt free software, which models geographic species distribution using
only local presence data and bioclimatic variables associated with each of these points
of presence. |
