City-dwelling is becoming more important for wildlife as the global human population
grows (Baker & Harris, 2007). Secondly, it is evident that increasing numbers of carnivores are using urban areas. For example, during the 1990s, there was a 15-fold increase in the numbers of nuisance coyotes Canis latrans removed annually from the Chicago metropolitan area (Gehrt, 2011); similarly, there has been a 10-fold increase in complaints about black bears Ursus americanus in urban Nevada (Beckmann & Lackey, 2008). Thirdly, it is biologically interesting that some species, but not others, do so well in urban environments. Understanding more about the biology of these animals is likely to aid our management and conservation of carnivores as a group. Finally, selleck products as Gehrt, Riley & Cypher (2010) pointed out, carnivores elicit strong feelings in people (e.g. fascination, admiration, fear and hate), which may be a manifestation of our ancestral predator–prey
relationships and which certainly mould and direct our interactions www.selleckchem.com/products/AZD2281(Olaparib).html with these animals. In this review, we summarize the history of terrestrial mammalian carnivore species as urban dwellers in a taxonomic framework (section: ‘History of carnivore urban adaptation’). We then examine how the ecology of carnivores is influenced by urban living, addressing their habitat utilization and diet (section: ‘How is the ecology of mammal carnivores influences by urban living?’). We explore the causes of mortality and the effects of increased density on carnivore behavior and sociality. In the following section (‘Which species make the best urban adapter/exploiter?’), we investigate features that may allow a species to become adapted to urban environments (i.e. taxonomy, body size, diet and phylogenetic history). Finally, we explore Sitaxentan the consequences of carnivore presence within cities for humans, and, in turn, what a future in urban areas may hold for carnivores. Carnivores have demonstrated a range of adaptation to living with humans (Fig. 1). Dogs and cats have lived in close association with humans
for millennia, and as human populations have spread, these animals have travelled with them, gaining access to some of the most remote locations on the globe. Their extremely adaptable nature has allowed dogs and cats to move out from human habitation to exploit new environments. A key example of this has been the establishment of the dingo Canis lupus dingo in Australia. Dingoes entered the continent with human settlers some 3500–4000 years ago (Corbett, 1995) and have since become established over the entire continent. Arguably, the cat is even more successful in its exploitation of habitats. Its high mobility and flexible biology makes the cat robust to habitat fragmentation (Crooks, 2002) and, coupled with transportation by humans (McKinney, 2006), these animals have spread largely unchecked over new landscapes (e.g.
