Advances in Algal Biology: A Commemoration of the Work of Rex Lowe
Author: R. Jan StevensonPublisher: Springer Science & Business Media
ISBN: 1402050704
Category : Science
Languages : en
Pages : 249
Book Description
Advances in Algal Biology: A Commemoration of the Work of Rex Lowe was written by students and colleagues of Rex Lowe to acknowledge his esteemed career that included exceptional contributions to research and teaching. Papers in the book cover a variety of topics in algal ecology, focusing on benthic algal ecology in freshwater ecosystems. The studies provide an unusual combination of small-scale experiments and large-scale regional surveys that bridge both basic and applied ecology. Ecologists, limnologists, phycologists, and environmental scientists will find valuable contributions to the development and application of algal research.

Book Description
The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems. With the controls on point sources reducing chemical contamination, new environmental challenges associated with nonpoint sources have emerged. To adequately deal with these new problems, EPA's Office of Research and Development recognized the need to develop an overall under standing of the condition of our ecological resources, the trends in their condition, and the stressors affecting these systems on a broad scale. Toward this end, the En vironmental Monitoring and Assessment Program (EMAP) was established by EPA and has been strategically developing the scientific tools and techniques to monitor and assess the status and trends of aquatic ecosystems. EMAP scientists have developed new indicators and probability-based de signs to fill data gaps in the development of regional-scale assessments of our aquatic resources, as required in the Clean Water Act. We have a scientifically de fensible approach that allows: 100 percent coverage of the aquatic resources within broad geographic areas and the formulation of reference 'conditions for es tablishing the health of these resources. The use of these indicators and designs were successfully demonstrated in the landscapes, streams, and estuaries of the mid-Atlantic states as part of the Mid-Atlantic Integrated Assessment (MAlA).
