ESTIMATION POPULATION SIZE PECCARIES (TAYASSU PECARI), IN THE “RIO NEGRO” FARM - BRASILIAN PANTANAL, DURING 2003 - 2004, BY MEANS CAPTURE AND RECAPTURE MULTIPLE METHOD

Abstract

The Tayassu pecari are predominantly distributed in conserved biomes and the maintenance of the species is very susceptible to human activity. In this context, it is important the search for methods of population estimation as well as apply robust methods that allow more accurate estimative. Therefore, this work aims to estimate the population of peccaries, on the Rio Negro farm (Aquidauana-MS) through the multiple captures and recapture method during the years 2003 and 2004, considering the assumption that the population is closed.    The estimate of the population size was obtained by the computational resampling and three procedures are compared. It was verified the marked difference between males and females for both years. The population size it was estimated in 134 and 192, however, by means the bootstrap method, a notable change in the distribution pattern of estimates was verified, being positively asymmetric and symmetric, for 2003 and 2004 respectively.
