A comparative, global analysis of behavior, genetics, physiology and
morphology of these species will help us to understand the evolutive
path that originated acoustic communication, as it is today, in the
species of the genus under study.
The present project, in addition to seeking to describe the
behavioral repertoire of the cavy-like rodents Kerodon rupestris
and Galea spixii, which inhabit the Brazilian semi-arid
region, also aims to associate the sound emissions used by the
species in question in each situation suggested, identifying the
reactions of both the emitting and receiving animals and their
context.
Acoustic communication is very important with regard to
communication at a distance, especially when other communicative
functions, such as smell and sight, are not efficient, either
because of dense vegetation or dim light. It may also have a
modulating function in the behavior of animals living in colonies,
such as the animals in question. Therefore, the study of acoustic
communication and the description of this repertoire are extremely
important in order to categorize the species’ actions (or behavior).
Fazenda Tamanduá, in the person of Mr. Pierre Landolt, not only
opened its doors to the development of this research, but also made
available to us part of its structure so that we could carry
out the work. We were also able to enjoy the unrestrained help of
its workers, who show a great deal of awareness in relation to the
importance of preserving species and the environment, and of
partnerships in scientific production and the generation of
knowledge.
The results of this research will be published in a future edition
of this journal.
