Global trade and the spread of human populations have increasingly moved thousands of native animal and plant species across the natural barriers that have kept them ecologically separated for millions of years. Because some of them thrive in their new regions and harm the environment, the economy, and human health, the prevention and management of such invasive species has become a major local, national, and international policy initiative. Yet even though ecologists have been studying the negative (and sometimes positive) environmental impacts of invasive species and trying to curb their proliferation, and even though their work has in some cases stimulated public conversation and policy, politicians have generally ignored their recommendations. As a result, ecologists have achieved limited success in slowing the spread of invasives. They ve been realizing that in order to fully characterize the impacts of these species, they need to engage with other relevant disciplines across the social and legal sciences as well as the humanities. Drawing together a wide variety of ecologists, historians, economists, legal scholars, policymakers, and communication scholars, Invasive Species in a Globalized World aims to facilitate a dialogue among these various disciplines in order to fully understand invasives and stop their spread. Addressing the numerous challenges associated with reducing invasive impacts, the contributors provide direct policy recommendations, strategies for communicating the risks of invasive species, and insight into how public discourse drives our response to these risks."

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.

The book provides the most comprehensive review of lamprey biology since Hardisty and Potter’s five-volume “The Biology of Lampreys” published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.

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.

Hagfishes and lampreys, both examples of jawless fishes, are elongated, eel-like animals lacking paired fins, and are the only living representatives of ancient creatures that gave rise to current species of fish and, eventually, humans. This volume provides an overview of the current status of knowledge on a variety of topics related to jawless fishes, including their taxonomy, zoogeography, phylogeny, molecular biology, evolution, life history, role in the ecosystem, and fisheries and management of hagfishes and lampreys worldwide. This is the first book dealing exclusively with the various aspects of jawless fish species throughout the world. It brings together a number of papers providing new data on jawless fishes, and offers readers a range of useful information within a single reference, reflecting the growing appreciation for hagfishes and lampreys worldwide.
