The sacred balance : rediscovering our place in nature

Abstract: In this extensively revised and enlarged edition of his best-selling book, David Suzuki reflects on the increasingly radical changes in nature and science -- from global warming to the science behind mother/baby interactions -- and examines what they mean for humankind's place in the world. The book begins by presenting the concept of people as creatures of the Earth who depend on its gifts of air, water, soil, and sun energy. The author explains how people are genetically programmed to crave the company of other species, and how people suffer enormously when they fail to live in harmony with them. Suzuki analyzes those deep spiritual needs, rooted in nature, that are a crucial component of a loving world. Drawing on his own experiences and those of others who have put their beliefs into action, "The Sacred Balance" is a powerful, passionate book with concrete suggestions for creating an ecologically sustainable, satisfying, and fair future by rediscovering and addressing humanity's basic needs.

Feeding Preferences of the Magellanic Penguin over Its Breeding Range in Argentina

Abstract: -The diet of Magellanic Penguins (Spheniscus magellanicus) was studied by stomach-pumping birds at five colonies (San Lorenzo, Punta Clara, Punta Loberia, Monte Leon and Punta Dungeness) over the species' latitudinal range in Argentina. A total of 159 birds were sampled during the period February 1986 to December 1988. Most prey items consisted of pelagic school fish, although squid and shrimps were also taken. At any one colony, birds appeared to be principally monoor bi-phagic and there were clear latitudinal differences in prey taken. Penguins in the northern colonies at San Lorenzo, Punta Clara and Punta Loberia consumed primarily anchovy (Engraulis anchoita) while birds at the two southerly colonies of Monte Leon and Punta Dungeness fed primarily on squid (Loligo spp. and Illex spp.), sprats (Sprattusfuegensis) and Hagfish (Myxine spp.). The strict dependence of Magellanic Penguins on commercially-exploited, schooling prey species makes the species particularly susceptible to changes in prey stocks, as has happened to congeners elsewhere that have suffered population crashes due to poorly-managed fisheries.
