Book Description
A benthic macroinvertebrate survey was conducted on the Butternut Creek, Otsego County, New York. Samples were collected from 18 sites between Basswood Pond and the confluence of Butternut Creek and the Unadilla River from 1 July 2002 to 15 July 2002. Assessments of physical habitat (PHA), family biotic index (FBI), percent model affinity (PMA), and percent Ephemeroptera, Plecoptera and Trichoptera (%EPT) were made at each site. Mean assessment results indicate that the habitat and water quality of Butternut Creek is in good condition. PHA results of 94.17 (+/- 19.42) indicate optimal habitat. Percent EPT values of 50.56 (+/- 20.98) are in the non-impacted range. FBI data averages 4.26 (+/- 1.16) revealing a non-impacted condition. A PMA of 62.61% (+/- 13.20) places the water quality in the slightly impacted range. The benthic community at each site was broken down according to functional feeding group (FFG). A significant decline in shredder populations was found as sampling proceeded down the course of the stream. No relationship was found between location on the stream and PHA. PHA did not have a significant effect on FBI, PMA or %EPT scores at each site.

Methods in Stream Ecology
Author: F. Richard HauerPublisher: Academic Press
ISBN: 0080547435
Category : Science
Languages : en
Pages : 894
Book Description
Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. - Exercises in each chapter - Detailed instructions, illustrations, formulae, and data sheets for in-field research for students - Taxanomic keys to common stream invertebrates and algae - Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers

Book Description
Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. - Presents algae as the important player in relation to environmental health - Prepared by leading authorities in the field - Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms - Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems

Pages : 345
Book Description
Long-term population monitoring is an important tool in our investigations of the role waterbirds play in their environment. This book is international in scope and presents information on species as diverse as the Common Loon, Harlequin Duck, and Semi-Palmated Sandpiper, and habitat in locations ranging from Iceland to Japan. Papers presented in this volume further our understanding of the important role that limnology plays in determining habitat suitability for waterbirds.
