Book Description
This volume focuses on the US-Canadian experience with the shared fishery resources of the Laurentian Great Lakes, a vast and complex ecosystem that holds 20 percent of the world's surface fresh water supply and a wide array of fish and fisheries. Written by scientists from federal, state, and provincial management agencies, contributions address current knowledge of the ecological, sociological, and policy issues that face the region's fishery managers and policy makers in both countries.

Coregonid Fishes of the Great Lakes
Author: Walter KoelzLampreys: Biology, Conservation and Control
Author: Margaret F. DockerPublisher: Springer
ISBN: 9402416846
Category : Science
Languages : en
Pages : 590
Book Description
This book, published in two volumes, provides the most comprehensive review of lamprey biology since Hardisty and Potter’s “The Biology of Lampreys” published more than 30 years ago. This second volume offers a synthesis of topics related to the lamprey gonad (e.g., lamprey sex ratios, sex determination and sex differentiation, sexual maturation, and sex steroids), the artifical propagation of lampreys, post-metamorphic feeding and the evolution of alternative feeding and migratory types, the history and status of sea lamprey control in the Laurentian Great Lakes and Lake Champlain, and an overview of contributions of lamprey developmental studies for understanding vertebrate evolution.

Author: Ecological Effects of Water-level Fluctuations in Lakes
Author: Karl M. WantzenPublisher: Springer Science & Business Media
ISBN: 1402091923
Category : Technology & Engineering
Languages : en
Pages : 184
Book Description
Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.
