Predação de plantas jovens de Euterpe edulis e invasão de lavouras de milho por Sapajus nigritus em remanescentes de floresta atlântica no sul do Brasil

Abstract

The almost complete replacement of the native vegetation of the Atlantic Forest by agriculture and livestock generated an altered matrix in which are embedded fragments of different sizes and historical use and degradation. In this study, the population density of Sapajus nigritus was estimated in two forest fragments surrounded by agricultural crops in southern Brazil. We use the method of linear transect between September 2011 and January 2013, covering 344.08 km in area and 216 km in another. We recorded 119 sightings and 35, respectively. In the first area the population density of Sapajus nigritus was 92.15 individuals / km2, and 32.10 individuals / km2 for the second area. While the lowest value is within the limits found for the species throughout its geographical distribution, the value of 92.15 individuals / km2 is among the highest ever recorded. In addition to offering food crops by anthropogenic factors such as low hunting pressure and predation, as well as composition and forest structure may be related to the densities found
