Journey of the Pink Dolphins: An Amazon Quest(more) »rank: 599583by: Sy Montgomery
: : Scientists call them Inia geoffransin, an ancient species of toothed whale whose origin dates back about 15 million years. To the local people of the Amazon, pink river dolphins are 'botos,' shape shifters that, in the guise of human desire, can claim your soul and take you to the Encante, an enchanted underwater world. As tributaries braid into a single river, Journey of the Pink Dolphins weaves ancient myth and modern science into one woman's search for these clusive creatures. With their melonlike foreheads and tubular snouts, pink dolphins look eerily familiar, like people in watery beginnings. No one ... |

Yet only recently have we begun to understand the scale of those impacts.Defying Ocean's End is the result of an unprecedented effort among the world's largest environmental organizations, scientists, the business community, media, and international governments ... |

Ecology of Desert Systems(more) »rank: 667571by: Walter G. Whitford
: :Conventional wisdom considers deserts stark, harsh regions that support few living things. Most people also believe that water alone makes the desert bloom. Ecology of Desert Systems challenges these conventional views. This volume explores a broad range of topics of interest to ecosystem, population, community, and physiological ecologists. Climate, weather patterns, geomorphology, and wind and water processes are examined as variables that affect the distribution of biota through fundamental ecosystem processes. Descriptions of morphological, behavioral, and physiological adaptations of desert biota illuminate, through the lens of patch dynamics, principles for understanding observed patterns of primary production, nutrient cycling, and the ... |

Ocean Life(more) »rank: 563574by: Sally Morgan, Pauline Lalor

This volume demystifies the complexity of the tides by systematically examining its many constituents and demonstrates that: Nature ... |


The story is pointedly set in the late 1980s, years before the establishment of the WNBA, so Monica's prospects for pro ball lie exclusively in Europe, while Quincy steps into the pros at home. It's a pleasure to see a character as passionate and fully developed as Monica, and Lathan gives a fiery portrayal (she had never played ball before the film, but you'd never tell from her performance). Prince-Bythewood favors her struggle over Quincy's and opens our eyes to her unique challenges with a sharp, savvy contrast. Alfre Woodard costars as Monica's harping mom (always trying to get her to be more ladylike) and Dennis Haysbert is Quincy's philandering father. Hoops fan Spike Lee produced. --Sean Axmaker
