A dominant paradigm in understanding and managing large herbivores is that, after introduction to new range or release from harvesting, the herbivore population increases to peak abundance, crashes to a lower abundance, and then increases to a carrying capacity lower than peak abundance. However, support for the paradigm has been largely anecdotal. We first developed two mathematical models to ...

Knowledge of acoustics and sound, an interest in music and his familiarity with tapping the wine barrels in his father’s inn, helped Auenbrugger develop the science of percussion. An empty barrel or a normal chest, gave a resonant sound on percussion, while a barrel filled with wine or the pleural cavity filled with an effusion, gave out a different note. He was also able to outline the cardiac...

Identification of a face is facilitated by adapting to its computationally opposite identity, suggesting that the average face functions as a norm for coding identity [Leopold, D. A., O'Toole, A.

Global Bioethics may be seen as the ultimate quid pro quo for the Land Ethic called for by Aldo Leopold in 1949• The core of that idea is conveniently expressed in the dedication of my first book on bioethics to Leopold directly quoting him.
