Mammals and their biomass on a Brazilian ranch

Abstract

The purpose of this paper is to present information on abundance and biomass of mammals on a cattle ranch consisting of a mosaic of pasture, scrub, and woodland, a habitat now representative of many areas in Brazil and neighboring countries. Between April 1977 and September 1978, the author studied wildlife intermittently on the Acurizal ranch (17 degree 45'S, 57 degree 37'W) at the western edge of the Pantanal, a swampy plain along the upper Paraguay River in the Mato Groso states of Brazil.
