Numerical Abundance as the Criterion for Successful Species
... A fact overlooked in connection with the Darwinian edict quoted is that predation tends to be proportional to population (McAtee, 1932, 1934, 1935). Rarity, in itself, protects both by evading notice and by forcing enemies to turn their attention to more abundant sources of subsistence. The prey-pre ...

Island restoration
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups such as New Zealand and Hawaii have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species.
