Some Changes in the Bottom Fauna of Green Bay, Lake Michigan from 1952 to 1969

Category : Aquatic invertebrates
Languages : en
Pages : 58
Book Description
Bottom samples were collected in lower and middle Green Bay in May 1969 on the same date, at the same 27 stations, and using the same methods as a 1952 survey. In 1969 there were fewer Oligochaeta and Chironomidae in the vicinity of the Fox River mouth. Elsewhere in the lower and middle bay oligochaetes and midge larvae were more abundant than in 1952 but most other benthic invertebrates were less abundant. The observed changes are interpreted as indicative of greater pollution and increased eutrophication during the intervening 17 years.

Book Description
After some conversations with Professor Dr. H. Caspers and other participants at the triennial congress of the International Association of Theoretical and Applied Limnology (S. I. L. ) held in Copenhagen, Denmark (1977), the senior editor approached the international delegates at the business meeting for approval of the concept of holding the First International Symposium on Aquatic Oligochaete Biology at Sidney (near Victoria) British Columbia on May 1-4, 1979. The S. I. L. agreed to sponsor such a meeting, and this sponsorship in turn led to the provision of space and technical facilities at the Institute of Ocean Sciences Patricia Bay, the Pacific Regional headquarters of the Ocean and Aquatic Sciences component of the federal Fisheri~s and Oceans Department. The National Research Council of Canada provided travel support for a number of non-Canadian participants. Invitations were sent to as many active workers in the field as the senior editor could name, and in addition two representatives of closely allied fields were invited - Dr. V. Standen who works with closely related but terrestrial species, and Dr. J. Grassle who works with polychaetes but especially with Capitella capitata which is much like an oligochaete in some aspects of its biolog- so much so that the senior editor in his salad days succumbed to some ill-founded advice and described Capitella as a new marine tubificid! The addition of these "outside" influences prevented the group from making a number of unfounded assumptions during discussions, and provided valuable cross-linkages.

Book Description
In aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors’ experience, of a number of current issues which have been raised in the literature.
