Book Description
Discovered the extent of morphological variation of the individual species of Oscillatoriaceae, a group of algae which cover a substantial part of the earth¿s barren surfaces & constitute a goodly proportion of the conspicuous plants in its bodies of water. The capabilities of these algae for structural change during natural growth in diverse habitats, & in a single habitat as the environment changes, have been ignored. Plants deviating from the ¿typical¿ as a result of such variability have been interpreted as atypical or anomalous for the species concerned or have been described forthrightly as taxa new to science. The outcome of this investigation is comparable with that of a similar study of the coccoid Myxophyceae by Drouet & Daily (1956). Illustrations.

Book Description
The 31 chapters provide a wealth of previously unpublished information, plus topic syntheses, for a wide range of ecological parameters. These include the physical driving forces that created and continue to shape the Everglades and patterns and processes of its flora and fauna. The book summarizes recent studies of the region's vegetation, alligators, wading birds, and endangered species such as the snail kite and Florida panther. This referee-reviewed volume is the product of collaboration among 58 international authors from 27 institutional affiliations over nearly five years. The book concludes with a synthesis of system-wide restoration hypotheses, as they apply to the Everglades, that represent the integration and a collective viewpoint from the preceding 30 chapters. Techniques and systems learned here can be applied to ecosystems around the world.

Book Description
Lakes of New York State, Volume I: Ecology of the Finger Lakes describes the state of Finger Lakes, which is a group of eleven elongated bodies of water of glacial origin in the west-central portion of New York, and its respective watershed. This book assesses the structure of the Finger Lakes' plant and animal communities and how these communities interact with the abiotic components of the environment. The condition of the lakes from the standpoint of fish population dynamics are also analyzed, including an examination of the various physical, chemical, and biological aspects of the lakes' ecosystem. This text ranks the Finger Lakes into a unilateral trophic list by tabulating their trophic information according to three commonly used indicator measurements— average summer Secchi disc depth, average summer chlorophyll a concentration, and average winter total phosphorus level. This publication is valuable to limnologists and ecologists working on temperate zone freshwater lakes.
