This study examined the role of water regime in the ecology of seasonally flooded prairie wetlands, and the potential for using water level manipulation as a seasonal marsh management tool. Specific objectives were 1) to determine the effects of water regime on decomposition of whitetop (Scolochloa festucacea), a dominant emergent grass of seasonal prairie wetlands, 2) to determine the influence of water regime on macroinvertebrate abundance in seasonal marshes, and 3)to compare whitetop forage yield under dry and seasonally flooded conditions. Distinct water regimes (permanent drought, permanent flooding, or seasonal flooding) were applied to 3 contiguous impoundments on the Delta Marsh, Manitoba, from April 1981 through July 1983. Responses within the litter, aquatic macroinvertebrate, and aboveground macrophyte components to each treatment were measured.Prolonged flooding hastened weight loss from whitetop litter.Differences in weight loss patterns were related to the length of.

Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. - Advances understanding of natural disturbances by combining geophysical and ecological processes - Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances - Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition

This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.

This study examined the seasonal differences in aquatic macroinvertebrate populations within and between the dominant vegetation types in a series of 5-ha experimental marshes in south-central Manitoba. Following periods of normal water depths, the marshes were flooded to 1-m above the existing cattail beds to determine the invertebrate response to above-normal flooding of marsh habitat. The effects of changing invertebrate levels on the waterfowl (Anatidae) and coot (Fulica americana) use of the experimental marshes were also examined. During periods of normal water depths, maximum nektonic invertebrate levels (densities, biomass, and number of taxa) were recorded during mid-summer in open water sites with dense beds of submersed vegetation. During the same time period, minimum nekton levels within the experimental marshes were recorded in stands of emergent vegetation. Benthic invertebrate levels were low in all cover types during periods of normal water depths. Factors affecting in.
