“…It had been proposed (Fitzgerald 1978;King 1982;Murphy 1992), and accepted (Choquenot & Ruscoe 2000;Blackwell et al 2001;Ruscoe 2001;King 2002), that winter breeding is necessary for mouse populations to reach high density in those forests.…”

“…Although commensal mouse populations breed year round (Bronson 1979), feral house mice in temperate ecosystems are seasonal breeders (Bronson 1979;Pye 1993;Singleton et al 2001; this study). In New Zealand they typically breed only in spring and summer (Efford et al 1988;Ruscoe 2001). Mice in Australian wheatfields have a longer breeding season when increasing to "plague" densities (Singleton & Redhead 1990;Singleton et al 2001).…”

Mice (Mus musculus) in New Zealand's Nothofagus forests reach peak densities after mast seeding, but the role of beech mast and winter breeding in these fluctuations is uncertain. In the Orongorongo Valley, near Wellington, seedfall was measured and mice were trapped quarterly in mixed hard beech (N. truncata) and podocarp/hardwood forest (100-250 m a.s.l.) from 1971 to 1993, and in silver beech (N. menziesii) forest at higher altitude (580-786 m a.s.l.) from 1973 to 1978. Density (indexed by the percentage of traps catching mice, adjusted for linearity; ± SE) reached peaks of 6.2 ± 1.0-13.8 ± 1.6 after masting in 1971, 1979, 1986, and 1990, but also without mast in 1975, 1977, 1982, and 1983. Females bred in spring and summer. In the lower-altitude population, most breeding in mast years preceded autumn seedfall, and almost no mice bred in winter. The density index peaked in the following spring when the population comprised overwintered mice. Apparent recruitment between Z03031;

“…Field specialists seem unanimous in viewing rats as strong competitors of mice, negatively affecting the rate of change in mouse abundance and even excluding them when resources are scarce (Choquenot & Ruscoe 2000;Courchamp et al 2000;Ruscoe 2001). It has been shown already that where populations of mice and ship rats coexist in New Zealand forests, mice are scarcer than rats (King et al 1996).…”

“…Such mouse population might be released from rat competition if the latter is suddenly removed, triggering an explosion of the mouse population. Such a dramatic increase could be disastrous as mice have been shown to be active predators of invertebrates, reptiles and even birds that can be 300 times their weight (Newman 1994;Fitzgerald et al 1996;Campos & Granadeiro 1999;Ruscoe 2001;Le Roux et al 2002;Smith et al 2002;Cuthbert & Hilton 2004;Wanless et al 2007).…”

Introduced vertebrate predators are one of the most important threats to endemic species throughout a range of ecosystems, in particular on islands in biodiversity hot spots. Consequently, the reduction of predator numbers is considered a key conservation action in the management of many native vertebrates vulnerable to predators. It is now established that control attempts may affect non-target species through trophic interactions, but little is known concerning their consequences on competitive relationships. We study a mathematical model mimicking the effects of controlling introduced species in the presence of their competitors.We used two competing rodents to illustrate our study: black rats, Rattus rattus, and mice, Mus musculus. Analyses of the model show that control of only one introduced species logically results in the dramatic increase of the overlooked competitor. We present empirical data that confirm our theoretical predictions. Less intuitively, this process, which we term 'the competitor release effect', may also occur when both introduced competitors are simultaneously controlled. In our setting, controlling both predators can promote their coexistence. This occurs as soon as the inferior competitor benefits from the differential effect of the simultaneous control of both competitors, that is, when the indirect positive effect of control (the removal of their competitors) exceeds its direct negative effect (their own removal). Both control levels and target specificity have a direct influence on the extent of this process: counter-intuitively, the stronger and more specific the control, the greater the effect. The theoretical validation of the competitor release effect has important implications in conservation, especially for control management.
