  abstract = {{T}he exogenous input of nutrients and energy into island systems fuels a large array of consumers and drives bottom-up trophic cascades in island communities. {T}he input of anthropogenic resources has increased on islands and particularly supplemented non-native consumers with extra resources. {W}e test the hypothesis that the anthropogenic establishments of super-abundant gulls and invasive iceplants {C}arpobrotus spp. have both altered the dynamics of an introduced black rat {R}attus rattus population. {O}n {B}agaud {I}sland, two habitats have been substantially modified by the anthropogenic subsidies of gulls and iceplants, in contrast to the native {M}editerranean scrubland with no anthropogenic inputs. {R}ats were trapped in all three habitats over two contrasting years of rainfall patterns to investigate: (1) the effect of anthropogenic subsidies on rat density, age-ratio and growth rates, and (2) the role of rainfall variability in modulating the effects of subsidies between years. {W}e found that the growth rates of rats dwelling in the non-subsidized habitat varied with environmental fluctuation, whereas rats dwelling in the gull colony maintained high growth rates during both dry and rainy years. {T}he presence of anthropogenic subsidies apparently mitigated environmental stress. {A}ge ratio and rat density varied significantly and predictably among years, seasons, and habitats. {W}hile rat densities always peaked higher in the gull colony, especially after rat breeding in spring, higher captures of immature rats were recorded during the second year in all habitats, associated with higher rainfall. {T}he potential for non-native rats to benefit from anthropogenic resources has important implications for the management of similar species on islands.},
