Application of a Dichotomous Key to the Classification of Sea Lamprey Marks on Great Lakes Fish

Book Description
This document augments the dichotomous key crated by Ebener et al. (2003) with photographs taken during the 2002 and 2003 workshops, and it is intended to help fishery agencies implement the King and Edsall (1979) protocol for classifying sea lamprey marks. Their illustrations represented the "idealized" types and stages of sea lamprey marks in comparison with the more complicated marks often observed in the field. We combined the original King and Edsall (1979) photographic illustrations with photographs made at the five workshops to create this sequel to the 1979 field guide.

Restoration of Aquatic Ecosystems

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

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.
