Book Description
Tidal creek systems serve as sentinel habitats, areas where the effects of human impacts may be seen before adverse affects are detectable in the larger ecosystem. Patterns of abundances of nekton in southeastern tidal creeks draining four land use classes were determined. Lower abundances of Palaemonetes shrimp species were found in headwater tidal creeks with higher levels of human impact. The pinfish Lagodon rhomboides was found in higher abundances in larger creeks having increased levels of human impact in the watersheds. A simplified food web of small nekton in six South Carolina tidal creeks was studied to illuminate one possible pathway for land use to affect the abundances of nekton. Food web analysis showed that the diets of shrimp in the more highly impacted creeks shifted from being dominated by particulate organic matter in the reference creeks to more varied diets in urban creeks, thus suggesting that alterations in the food web are one possible cause for the alteration in abundances of nekton with increasing levels of human impact.

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.
