The development of the computer interface for ecological information transfer was supported with an scholarship from the Pew Charitable Trusts in Integrated Approaches to Training in Conservation and Sustainable Development. Many people made valuable contributions to this dissertation. First among them was my major professor, John W. Day, whose early comments shaped the structure of the whole project, and his constant insightful ideas and suggestions significantly strengthened the flow of this research. The members of my advisory committee, Drs. Michael E. Orlowski, Lawrence J. Rouse, Richard F. Shaw, Fred H. Sklar, Paul H. Templet, who always displayed such a keen interest in my work; I can't thank them enough for their contributions and positive criticisms along the way. There are some special people that I would like to mention, Dr. Alejandro Ybhez-Arancibia, who as my national advisor, constantly steered me towards resource management, specially from the Mexican perspective. His suggestions were indispensable in bringing me back to reality. The special and golden opportunity that Dr. Ybftez-Arancibia gave me to demonstrate the interface to our President was beyond any academic interests. A heartfelt thanks to all the staff of the EPOMEX program, particularly Ana Laura, whose ideas and fun were always such a refreshing welcome. Thanks to all the students at the Dept, of Oceanography and Coastal Sciences, especially from the old crew, Dano and Rick, who were always there to share a laugh and a few beers, as well as constantly improving on their Spanglish. Finally, I would like to thank my family, Ana Maria, Ana, Rodolfo, Raul and Carolina for a continuous supply of love and understanding so far away from home. Alejandra and Lorena, I miss you girls.

  • Effects of Eutrophication on Stream Ecosystems

    Effects of Eutrophication on Stream Ecosystems

    EFFECTS OF EUTROPHICATION ON STREAM ECOSYSTEMS Lei Zheng, PhD and Michael J. Paul, PhD Tetra Tech, Inc. Abstract This paper describes the effects of nutrient enrichment on the structure and function of stream ecosystems. It starts with the currently well documented direct effects of nutrient enrichment on algal biomass and the resulting impacts on stream chemistry. The paper continues with an explanation of the less well documented indirect ecological effects of nutrient enrichment on stream structure and function, including effects of excess growth on physical habitat, and alterations to aquatic life community structure from the microbial assemblage to fish and mammals. The paper also dicusses effects on the ecosystem level including changes to productivity, respiration, decomposition, carbon and other geochemical cycles. The paper ends by discussing the significance of these direct and indirect effects of nutrient enrichment on designated uses - especially recreational, aquatic life, and drinking water. 2 1. Introduction 1.1 Stream processes Streams are all flowing natural waters, regardless of size. To understand the processes that influence the pattern and character of streams and reduce natural variation of different streams, several stream classification systems (including ecoregional, fluvial geomorphological, and stream order classification) have been adopted by state and national programs. Ecoregional classification is based on geology, soils, geomorphology, dominant land uses, and natural vegetation (Omernik 1987). Fluvial geomorphological classification explains stream and slope processes through the application of physical principles. Rosgen (1994) classified stream channels in the United States into seven major stream types based on morphological characteristics, including entrenchment, gradient, width/depth ratio, and sinuosity in various land forms.

Acknowledgments First I would like to thank my parents, Linda and Salvador Salinas, for their unwavering support during my graduate studies; to them I dedicate this dissertation. At the University of Texas at Austin, I am greatly indebted to my academic advisor, Dr. Matthew Butler, who for the past six years has provided insightful and constructive feedback on all of my academic work and written many letters of support on my behalf. I am also grateful for my dissertation committee members, Professor Jonathan Brown, Professor Seth Garfield, Professor Virginia Garrard-Burnett, and Professor Samuel Brunk, who all read and provided insightful feedback on this dissertation.

The experiment was conducted at the experimental wastewater treatment plant of the Agronomic and Veterinary Medicine Institute (AVI) of Rabat, Morocco, using a HRPTS in a fish pond receiving the plant effluent. The effluent was highly dominated by phytoplankton (99.95%). Silver carp could survive and grow in the fish pond. Production was 37 kg with a very low mortality rate (12%). The high specific intestine weight (7%) and intake rates of biomass and phytoplankton by silver carp (616 g kg-1 of fish day-1 and 1.6 x 1011 cell kg-1 of fish day-1, respectively) demonstrated the importance of the feeding activity of the fish. Zooplankton intake rates were lower (2 x 107 bodies kg-1 of fish day-1). The high intestine index (3 to 4.3 for fish sizes of 14 to 22 cm) and the dominance of phytoplankton in the gut contents (99.95%) confirmed an omnivorous/ phytoplanctivorous diet.
