Alexander Strohmaier many island species lost defences that evolved in mammal-dominated ecosystems and gained new defences against bird-dominated islands. However, the study of island evolution has been taxonomically compartmentalised, with research on island animals and plants being conducted independently of one anot

Romeo Brunetti,Klaus Fredenhagenon stems largely from observations of intense damage from invasive mammalian herbivores on islands. However, this evidence is misleading because most oceanic island plants have not evolved with native mammalian herbivores, and so should not have evolved defenses against them. In contrast, many islan

There, to first approximation, one is left with the problem of quantum field theory on Lorentzian manifolds. Surprisingly, this seemingly modest approach leads to far reaching conceptual and
