Extinctions in Ecological Communities – direct and indirect effects of perturbation on biodiversity

To my Mother and Father. It's all because of you. Thank you! " Doing science is not such a barrier to feeling or such a dehumanizing influence as is often made out. It does not take the beauty from nature. The only rules of scientific method are honest observations and accurate logic. To be great science it must also be guided by a judgment, almost an instinct, for what is worth studying. No one should feel that honesty and accuracy guided by imagination have any power to take away nature's beauty. "
