Feral swine damage and damage management in forested ecosystems. (2009, background): “…Islands suggests that feral swine have sustained a large breeding population of golden eagles (Aquila chrysaetos), which in turn have caused the near extirpation of 3 subspecies of island fox (Urocyon littoralis) through increased predation (Roemer et al., 2001, 2002; Knowlton et al., 2007).”
Endangered, apparently: the role of apparent competition in endangered species conservation (2009, background): “…et al., 2002; Wittmer et al., 2007), and predator functional and numeric responses (Norbury, 2001), as well as correlative analyses of resource, prey and predator density data over space or time (Taylor, 1979; Harrington et al., 1999; Roemer et al., 2001; Robinson et al., 2002; Pope et al., 2008).”
Population‐level declines in Australian predators caused by an invasive species (2009, background): “Alternatively, native predators may consume invasives, thereby reducing invader populations while increasing their own biomass (Roemer et al., 2001; Noonburg & Byers, 2005).”
Allee Effects in Ecology and Conservation (2008, background): “Before the introduction of pigs, eagles were only transient visitors to the Channel Islands, since fox populations by themselves did not provide enough prey to sustain a permanent population, but since the introduction of pigs eagles have established resident populations on the northern islands (Roe”
Mammal invaders on islands: impact, control and control impact (2003, background): “Researchers on these islands pointed out that the decline in foxes was linked to a coincident increase in golden eagle (Aquila chrysaetos ) predation (Roemer, 1999; Roemer et al., 2001).”
The Ecological Role of the Mammalian Mesocarnivore (2009, background): “Furthermore, on San Miguel, where skunks are absent, the decline in foxes resulted in outbreaks of island deer mice, Peromyscus maniculatus (Coonan et al. 2000, Roemer et al. 2001).”
Non-indigenous ungulates as a threat to biodiversity (2009, methodology): “Roemer et al. (2001) used demographic information, observations and modelling to show that hyper-predation induced by the introduction of S. scrofa leads to population declines in an indigenous species (supporting information Table S5).”
