Resumen:
Exotic mammals in South America represent
about 20% of world mammal introductions. The
aim of our paper is to provide a global assessment of
the exotic mammals of Argentina, their pathways,
impacts, and a synthesis of their attributes as potential
invasive species. We reviewed and compiled data
from a diversity of sources and databases on alien
mammals occurring in feral state exclusively. We
recorded 18 species of exotic mammals for Argentina.
The majority of introductions occurred between the
18th and 19th centuries and their ports of entry were
located in temperate ecosystems, between 34 and 55
SL. Most of their entry pathways were associated with
human activities (e.g. sport hunting, food and fur
industry). The exotic mammals occupy ecoregions
similar to their original distributions, but most of them
have experienced a range expansion to novel habitats.
The fauna of exotic mammals of Argentina represents
a good opportunity to understand the dynamics of the
invasion process as they represent a diversity of
ecological groups and environmental contexts. and 55
