Virtual Issue - Domestic Carnivores and Wildlife Conservation

Within the field of conservation ecology, the importance of invasive species has long been recognized. Invasive animals are of particular concern when they are vertebrate carnivores, perhaps because these taxa are able to persist in diverse habitats and once comfortably embedded in these novel setting, are often able to instigate strong declines in prey species, or indeed, trophic cascades. The pages of Animal Conservation are littered with articles on invasive vertebrate carnivores.
Two carnivorous species blur the line when it comes to assessing whether a taxon is invasive: the domestic dog (Canis familiaris) and cat (Felis catus). Because they are often desired and subsidized human commensals, we rarely consider the ecological role of these species when they are either unowned or beyond the control of their ‘owners’ (whether free-ranging out of ear-shot or as animals that have left the fold and reverted to a feral lifestyle). Thus while conservationists, and sometimes the general public, are often attuned to some concerns regarding the impacts of cats on birds, or the potential for dogs to hybridize with wolves (C. lupus), many in this same audience are unaware of other concerns regarding these predators. While recent syntheses (Denny & Dickman, 2010; Hughes & Macdonald, 2013; Gompper, 2014; Nogales et al., 2014) have served to bring these issues to the forefront for ecologists and conservationists, much remains unclear. For example, in some landscapes free-ranging dogs and cats have existed for thousands of years. Furthermore, in some localities free-ranging populations of these species may serve as ecological surrogates of native carnivores that have been lost due to anthropogenic impacts. Recognition of such patterns suggests that understanding the impacts of domestic dogs and cats on wildlife requires in-depth research and nuanced interpretation of the ensuing data.
The extent of research on how domestic carnivores influence wildlife of conservation concern can be observed on the pages of Animal Conservation, where numerous articles on the theme have been published. In this Virtual Issue, eleven articles published over the past decade are highlighted. These papers collectively reveal the diversity of ecological interactions that domestic carnivores have with wildlife. The articles examine these interactions from diverse perspectives, with foci that include edge effects, predation, scavenging, disease maintenance and transmission, and hybridization.
