Download or read book The Seasonal Occurrence and Distribution of Stoneflies Plecoptera of a Western Oregon Stream written by Cary Dean Kerst and published by . This book was released on 1970 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plecoptera were collected from four sampling stations selected to represent a range of conditions on Oak Creek, a small woodland stream originating in the foothills of the Oregon Coast Range. The elevation of Site I was 700 ft. while the lowest site was located at 225 ft. Monthly benthos samples were taken for one year from a riffle and glide section at each site using a stovepipe sampler (6 in. dia.) and a standard tropical fish net. Samples were sorted in the laboratory and Plecoptera identified and placed into 1 mm size classes. Emergence of adults was measured for 13 months using a tent-shaped trap (1 m2) at each site. Traps were checked once or twice weekly. Forty-two species of Plecoptera were found in Oak Creek. The number of species is very large when compared with other studies. The stonefly fauna is fairly similar to that reported 35 years ago. Thirty-seven of the 42 species complete emergence during the spring. Temporal separation is marked in the emergence periods of Nemoura and Leuctra. Examples of split emergence periods and early emergence of males were found. Life cycle information is given for a number of species and genera. Using the Shannon-Wiener function, diversity of emerging adults ranks by season as: Spring> Summer> Winter> Fall. The diversity of the sites on a yearly basis is: II> I> III> IV. Using a percentage of similarity index it is concluded that Sites I and II are very similar. Site III is intermediate while Site IV is quite different. A number of examples of restricted distributions are cited. These examples illustrate that differences in longitudinal distribution are important in ecological segregation. Herbivorous stoneflies (suborder Filipalpia) comprise a greater proportion of the fauna at the upper site while predaceous stoneflies (Setipalpia) predominate in the lower areas. Water depth and amounts of leaves and silt are important factors in determining the distribution of stoneflies. Most species are abundant in leaf drifts. Microhabitat selection does not appear to be rigorous.

Download or read book Nymphs Stoneflies Caddisflies and Other Important Insects written by Ernest Schwiebert and published by Rowman & Littlefield. This book was released on 2007-09-01 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume II After the mayfly family, detailed in Nymphs: The Mayflies, the fly fisher must know the caddisfly, stonefly, and midge populations just as well to catch trout that are keyed in on such insects. Nymphs: Caddisflies, Stoneflies, and Other Important Species gives the reader all the essential information about identifying individual species of these insects throughout their North American range, and then delves into detailed instructions for scores of artificial patterns to imitate them. Few books in fishing literature have focused so closely on so many individual species of the particular genera of aquatic insects in this volume. And just as in Nymphs: The Mayflies, this book contains numerous stories and anecdotes from Schwiebert's travels that illuminate the selection and use of nymph patterns, and recount great days spent on the water as interpreted through one of the great minds of modern fly fishing.

Available in PDF, EPUB and Kindle. Book excerpt: This account provides the first comprehensive coverage of the insect and other arthropod pests in the urban environment worldwide. Presented is a brief description, biology, and detailed information on the development, habits, and distribution of urban and public health pests. There are 570 illustrations to accompany some of the major pest species. The format is designed to serve as a ready-reference and to provide basic information on orders, families, and species. The species coverage is international and based on distribution in domestic and peridomestic habitats. The references are extensive and international, and cover key papers on species and groups. The introductory chapters overview the urban ecosystem and its key ecological components, and a review of the pests status and modern control strategies. The book will serve as a professional training manual, and handbook for the pest control professionals, regulatory officials, and urban entomologists. It is organized alphabetically throughout.
