“…Similarly, the introduction events listed by Bertolino and Lurz (2013) for redbellied squirrels in Japan also indicate the occurrence of 17 new introductions after a lag period of approximately 20 years, though we cannot discriminate between multiple introductions and translocations within the country. Table 1 Year of introduction and number of red-bellied squirrels released at nine sites located in the city of Buenos Aires, and the provinces of Buenos Aires and Santa Fé, Argentina (see Fig.…”

“…population has been reporded in Italy though taxonomic identification is still pending . In all countries of introduction, only one or two Callosciurus populations have been reported with the exception of Argentina and Japan where several invasion foci have been described Bertolino and Lurz 2013). Native habitat in Southeast Asia includes tropical and subtropical evergreen forests and also conifer forests, while various arboreal habitat types are inhabited by C. erythraeus in introduced ranges such as natural forests, fruit and timber plantations, and parks and gardens in rural and urbanised areas; its highly arboreal habits relates to nesting on trees and feeding on vegetable matter mainly obtained from trees and shrubs .…”

“…Long (2003) provides accounts of 337 mammal species moved around the world (around 6% of the global mammal fauna), but some of this number have been re-introduced rather than introduced, while other mammal species with known introductions (e.g. Callosciurus finlaysonii, Bertolino and Lurz 2013) are missing from the compilation. A recent study by Capellini et al (2015) identified 232 mammal species as having been introduced (c.4% of the total mammal species richness) based on data in Long (2003) and other sources.…”

Patterns of selectivity in introductions of mammal species worldwide

Humans have an extremely long history of transporting and introducing mammal species outside their native geographic ranges. The characteristics of the species introduced (taxonomy, life-history, ecology, environment) can all influence which traits are available (and selected) for establishment, and subsequent invasive spread. Understanding the non-randomness in species introductions is therefore key to understanding invasions by alien species. Here, we test for selectivity in the identities and traits of mammal species introduced worldwide. We compiled and analysed a comprehensive database of introduced mammal species, including information on a broad range of life history, ecological, distributional and environmental variables that we predicted to differ between introduced and non-introduced mammal species. Certain mammal taxa are much more likely to have been introduced than expected, such as Artiodactyls in the families Bovidae and Cervidae. Rodents and bats were much less likely to have been introduced than expected. Introduced mammal species have significantly larger body masses, longer lifespans and larger litter sizes than a random sample of all mammal species. They also have much larger native geographic ranges than expected, originate from significantly further north, from cooler areas, and from areas with higher human population densities, than mammal species with no recorded introductions. The traits and distributions of species help determine which have been introduced, and reflect how the evolutionary history of mammals has resulted in certain species with certain traits being located in the way of human histories of movement and demands for goods and services. The large amount of unexplained variation is likely to relate to the intrinsically stochastic nature of this human-driven process. Blackburn et al. / NeoBiota 33: 33-51 (2017) 34

“…Squirrels have an enormous invasive capacity, as demonstrated by Callosciurus erythraeus and Sciurus carolinensis , which are able to successfully colonise new areas from as few as 10 initial individuals, causing considerable environmental damage in the new areas and being extremely difficult to eradicate (Palmer et al. , Bertolino & Lurz ).…”

NEOSQUIRREL: a data set of ecological knowledge on Neotropical squirrels

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.
