Jerry Dennis, Glenn Wolff (Illustrator), The Bird in the Waterfall : A Natural History of Oceans, Rivers, and Lakes Amazon:$18.20
Dennis, a frequent contributor to Smithsonian and Wildlife Conservation, lives near Lake Michigan and has always
been curious about bodies of water. He shares his fascination while discussing why water changes color, how dowsing
locates subterranean springs, what causes ocean currents, how a lake freezes, and why rivers meander. Contrary to what
seems most logical, rivers meander because flowing water seeks consistency and tries to deepen shallows, fill in deep
spots, and smooth out rapids and waterfalls. Dennis also describes the organisms that live in water: algae and bacteria
that give color to the hot springs in Yellowstone National Park; North American dippers and torrent ducks of the Andes
that thrive in rushing white water; pupfishes that can survive in hot water up to 113 degrees; and flamingos whose
specialized beaks are adept at filtering algae and diatoms from the saline and soda lakes in which they feed.
Explores the mysteries of the world's oceans, rivers, and lakes, in a nature study that addresses such topics as the
sources of hot springs and geysers, marine animal migration, and waterfalls.
Mark W. Denny, Air and Water : The Biology and Physics of Life's Media Amazon: $65.00
Addressing general readers and biologists, Mark Denny shows how the physics of fluids (in this case, air and water) influences the often fantastic ways in which life forms adapt themselves to their terrestrial or aquatic "media."
