This new collection focuses on the impact of sprawl on biodiversity and the measures that can be taken to alleviate it. Leading biological and social scientists, conservationists, and land-use professionals examine how sprawl affects species and alters natural communities, ecosystems, and natural processes. The contributors integrate biodiversity issues, concerns, and needs into the growing number of anti-sprawl initiatives, including the "smart growth" and "new urbanist" movements.

Fragments of wisdom from the ancient world In the sixth century b.c.-twenty-five hundred years before Einstein--Heraclitus of Ephesus declared that energy is the essence of matter, that everything becomes energy in flux, in relativity. His great book, On Nature, the world's first coherent philosophical treatise and touchstone for Plato, Aristotle, and Marcus Aurelius, has long been lost to history--but its surviving fragments have for thousands of years tantalized our greatest thinkers, from Montaigne to Nietzsche, Heidegger to Jung. Now, acclaimed poet Brooks Haxton presents a powerful free-verse translation of all 130 surviving fragments of the teachings of Heraclitus, with the ancient Greek originals beautifully reproduced en face.
