Resumen:
The enemy release hypothesis (ERH)postulates that during the invasion process an introducedspecies is released from the natural enemiesthat regulate its populations, promoting its invasionsuccess in the new environment. Callosciurus erythraeusis a sciurid native to Southeast Asia that hasbeen successfully introduced into Argentina and otherAsian and European countries. The aim of this studywas to provide new parasitological data on thisspecies and to compare it with studies in native andother introduced ranges under the framework of theERH. We proposed two working hypotheses: (1) ananalysis at the community level to compare theprevalence, abundance and identity of parasites of C.erythraeus and sympatric native mammals in the maininvasion focus of Argentina, and (2) an analysis at thebiogeographical level to compare parasite richness innative and introduced ranges of C. erythraeus andparasite prevalence and richness among introducedregions with different invasion success (using populationdensity and spread as proxy variables). Thecommunity analyses indicated that C. erythraeus haslost its specific parasites in Argentina and that it has alower level of parasitism than other native mammals.
