Project Update: November 2009

The first part of the project(fieldwork) was finished in the dry season (September - October 2009).The study was conducted in the lower part of the Mamoré, the Madera, the Abuna and the Negro rivers, all forming part of the Amazon basin in the northeast of the Beni and Pando departments.

A large amount of field data was collected. Physical characteristics of the rivers were measured, as well as chemical parameters (temperature, pH, transparency, TDC and conductivity). A census of river dolphins was conducted using standard methodologies. The analysis allows the estimation of relative abundance and the elaboration of distribution maps.
