ABSTRACT1. Rodents are traded as pet species, a practice that frequently results in new introduced populations. This is particularly true for tree squirrels where often only a few founders can establish viable colonies. 2. Here we review the worldwide introductions, ecology and impacts of two tree squirrel species, Callosciurus erythraeus and C. finlaysonii, and discuss the elements of a strategy to reduce squirrel introductions and settlements. 3. C. erythraeus has established viable populations in Argentina,

“…Several squirrel species are also able to inhabit modified and urbanized habitats. Consequently, introduced squirrel populations of 18 species have already been reported in 23 countries over five continents (Bertolino 2009;Jessen et al 2010). The long-studied case of introduction of the grey squirrel Sciurus carolinensis in Europe illustrates their invasive potential, their impact on native fauna and plantations, and how social support may determine the failure or success of a control program (Bertolino and Genovesi 2003;Gurnell et al 2004;Bertolino et al 2014).…”

“…In Peru, publications mainly relate to study sites in the north and east of the country, in which the departments of Loreto, Madre de Dios, and Piura have three, three, and four publications, respectively. In the capital Lima, we found two publications about the ecology of an introduced population of Simosciurus nebouxii (Jessen et al 2010). We found no publications about squirrel ecology in 19 departments of Peru.…”

The squirrels (Sciuridae), with 292 species, make up the second most diverse family of rodents. Squirrels play important roles as seed and spore dispersers and seed predators in all regions where they occur. In Neotropical regions, around 28 species of squirrel are recognised. However, our knowledge of the ecology of the Neotropical Sciuridae is severely incomplete, lacking in the most basic ecological information for most species. We reviewed the literature in English, Spanish, and Portuguese, for all squirrel species in the Neotropical biogeographic region, summarising ecological interactions between squirrels and the local biota, population density records, the number of publications, and the distribution of study sites. We found information for 20 squirrel species (71% of the recognised species), from 15 countries, in 48 publications containing 126 population density records and 155 publications containing 649 ecological interactions. The most studied species were Guerlinguetus brasiliensis, Notosciurus granatensis, and Sciurus variegatoides, with 53% of all publications, whereas for eight species of Microsciurus, we found no publications. The density of Neotropical squirrels varied from 0.08 to 100 individuals per km2 and was negatively correlated with forest area. Neotropical squirrels were recorded eating 174 plant taxa, five fungus taxa, four invertebrate taxa, and one species of vertebrate. Palms were common in the diet of squirrels (30 palm species, 27% of feeding records). Squirrels cached 28 plant species, of which 15 were palms. Sixty‐five taxa of parasites are documented to occur in Neotropical squirrels, and the most common were Enderleinellus lice. Zoonotic parasites, including trypanosomes, Leptospira spp., Leishmania spp., and plague were also reported. Our review reveals the main information gaps in the current knowledge about the ecology of Neotropical Sciuridae and maps the geographic distribution of the available information throughout South and Central America. Squirrels often thrive in small forest fragments and fulfil important roles as seed dispersers and prey for mesopredators.
