“…adult SVL) and more fecund reptiles were more likely to succeed in establishing novel populations. Interestingly, a similar pattern in body size has been found in some fishes (Ruesink, 2005), insects (Lester, 2005) and mammals (Jeschke & Strayer, 2006;Pereira-Garbero et al, 2013), but not in birds . Our results support the idea that smaller-bodied organisms are more successful when introduced as they are less prone to extinction (Jeschke & Strayer, 2008;Tingley et al, 2013) and may be related to greater niche availability for smaller-bodied species (Meiri, 2008), reduced susceptibility to human-altered landscapes associated with the introduced locations, or differences in early detection by management officials.…”

Aim Non-native reptiles are often detrimental to native communities and ecosystems and can be extremely difficult to manage once established. Thus, there is considerable interest in predicting the likelihood of establishment of nonnative reptiles. We assessed three hypotheses describing possible factors contributing to the successful establishment of introduced reptiles in an effort to better identify potential invaders.Methods Using a global invasion database (1307 introductions of 398 species) and Bayesian generalized linear mixed models, we tested the relative importance of event-level (e.g. propagule pressure), location-level (e.g. climate matching) and species-level (e.g. parthenogenesis) factors in reptile establishment success. ResultsThe factors that positively influenced establishment success included: (i) Event-level: longer time since initial introduction, greater number of introduction events and intentional introductions; (ii) Location-level: smaller differences in latitude between native and introduced ranges and the presence of native congeners in the introduced range; and (iii) Species-level: smaller body size, herbivores, larger native range size, parthenogenesis and high fecundity.Main conclusions We found that location-level factors were most important in describing reptile establishment success, followed by event-and species-level factors, respectively. This pattern matches closely with what others have found in a variety of vertebrate taxa. However, the importance of species traits may be underestimated considering the insufficient knowledge of reptile life history within introduced ranges. Importantly, individual variables from all three hypotheses contributed to global reptile establishment. Managers should be especially cognizant of small herbivorous and fecund reptiles that are frequently introduced into areas with a strong climate match to their native range. Further, parthenogenesis greatly facilitated establishment, indicating that obligate parthenogenetic species may become ubiquitous through modern globalized trade.

“…This severe defaunation occurred by the end of the 1800s and the early 1900s, when livestock populations were already established. Moreover, during the early 1900s, wild pigs, goats, Asian buffalo and two species of exotic deer were introduced into Uruguay and formed established wild populations [45, 70]. Wild pigs are now widely distributed in Uruguay and could be a food source for D. rotundus [70–72].…”

The emergence of vampire bat rabies in Uruguay within a historical context

Pathogen spillover from wildlife to humans or domestic animals requires a series of conditions to align with space and time. Comparing these conditions between times and locations where spillover does and does not occur presents opportunities to understand the factors that shape spillover risk. Bovine rabies transmitted by vampire bats was first confirmed in 1911 and has since been detected across the distribution of vampire bats. However, Uruguay is an exception. Uruguay was free of bovine rabies until 2007, despite high-cattle densities, the presence of vampire bats and a strong surveillance system. To explore why Uruguay was free of bovine rabies until recently, we review the historic literature and reconstruct the conditions that would allow rabies invasion into Uruguay. We used available historical records on the abundance of livestock and wildlife, the vampire bat distribution and occurrence of rabies outbreaks, as well as environmental modifications, to propose four alternative hypotheses to explain rabies virus emergence and spillover: bat movement, viral invasion, surveillance failure and environmental changes. While future statistical modelling efforts will be required to disentangle these hypotheses, we here show how a detailed historical analysis can be used to generate testable predictions for the conditions leading to pathogen spillover.

1.A better understanding of the effects of exotic species is fundamental for ecosystem management, given that biological invasions are major agents of change affecting native biodiversity worldwide. However, exotic species can also have positive effects on native communities, for instance by providing additional food sources. 2. We reviewed dietary studies in the scientific literature published between 1980 and 2016 in order to examine the role of exotic mammals in the diets of 42 terrestrial species of the mammalian order Carnivora from South America. We recorded information about species' characteristics and analysed the ways in which they relate to exotic mammal consumption. 3. We found 62 references in which 11 carnivores from four families were reported to consume exotic mammals. Using only dietary studies in which the frequency of occurrence of each prey item was presented, we compiled 152 cases from 56 papers. 4. The frequency of occurrence of exotic mammals in the diet of South American carnivores reached on average 21%. The more common prey-carnivore interactions occurred with exotic lagomorphs, while exotic ungulates were less frequently consumed and were only preyed upon by pumas Puma concolor. Consumers with mainly carnivorous habits consumed exotic mammals more frequently than frugivorous or omnivorous species. 5. The carnivore species and the location of the study area influenced the frequency of occurrence of exotic mammals in the diets described. Certain carnivores, including the puma, culpeo fox Lycalopex culpaeus, Pampas fox Lycalopex gimnocercus, lesser grison Galictis cuja and Molina's hog-nosed skunk Conepatus chinga, consumed more exotic mammals than average, and the occurrence of exotic mammals was the highest in the diets of carnivores in the southwestern regions of South America. 6. Exotic mammals in South America can create new food web interactions in the native carnivore community and can serve as an important food resource for some native species. This is particularly true in human-transformed landscapes, where native prey populations have declined. Thus, it is important to consider the role of exotic mammals in the conservation of native carnivore populations.
