Habitat-use patterns of the coypu Myocastor coypus in an urban wetland of its original distribution

The coypu Myocastor coypus Molina, 1782 is a semi-aquatic rodent native to Southern South America. In Argentina, it is an important fur resource for rural communities, and there is no evidence of its behaviour as a pest. Between October 2003 and February 2004, studies of habitat use at macro and mic...

In Argentina, it is an important fur resource for rural communities, and there is no evidence of its behaviour as a pest.

At the macrohabitat scale, the lower the herbaceous vegetation availability at the shore, the greater was the effective usage area.

The absence of hydrophilous vegetation, natural predators and human activity during the highest activity hours, in addition to suitable food resources around the year are considered to favour the coypu's behaviour as a pest in these environments.
