Potential distribution of vouacapoua americana aubl. In the brazilian amazon and the impact of the change in land use

Abstract

Predictive modelling has been used to analyze species geographic distribution based on conditioning variables. The objective of this work was to describe a potential distribution of Vouacapoua americana to the Amazonian territory, checking if the species is under anthropogenic pressure in the occurrence sites. Data on the occurrence of the species were used, using records in herbariums and climatic variables derived from precipitation and temperature. Models were generated using the maximum entropy algorithm and validated from confusion matrices and the area under the curve. Secondary data on land use, deforestation, pastures and forest fires were processed in the open gis QGIS 3.14. The species was found in northern South America. A total of 294 foci of calories and 98,521 km² of pastures were found in endemic areas of the Vouacapoua americana in the Brazilian Amazon. The result is that the species receives anthropogenic pressure, making it necessary for public policies to conserve biodiversity. © 2021, Universidade Federal de Pernambuco. All rights reserved.
