Abstract

The AEHMS, via its journal (Aquatic Ecosystem Health and Management) and the Ecovision World Monograph Series, has been actively engaged in promoting great/large lakes research. Consequently, it established a working group “The Great Lakes of the World-GLOW” for bringing together large lakes researchers to exchange ideas and technology. GLOW embarked on organizing special symposia which resulted in several peer-reviewed publications and special issues. In a short period of about 15 years, the AEHMS has published 11 peer-reviewed books under the banner of Ecovision World Monograph Series (Table 1).Over the past nine years 12 special issues of Aquatic Ecosystem Health and Management have been published dealing with great/large lakes (Table 2).Most of the manuscripts included in this special issue originated from the two sessions organized at the following international conferences: “Managing the large lakes of the world: Health, Integrity and risks”Limnological Congress (SIL), Montreal, Quebec, Canada, 2007“Great Lakes tomorrow: Research tools, toys and techniques”International Great Lakes Research Conference (IAGLR),Penn State University, University Park, Pennsylvania, 2007The papers have been categorized on a continental basis: North American, European and African, and reflect a great variety of topics across these continents. For North America, the themes comprised characteristics of poorly known Canadian lakes, geological history, remote sensing, and aquatic protected areas of the Great Lakes. The European contributions dealt with climate, water quality, phytoplankton, zooplankton, optical counters and remote sensing, the African papers focused mainly on fisheries of Lakes Victoria, Tanganyika, Kivu and Naivasha. One contribution, from Dr. Ken Minns, on Canadian lakes was an invited article.We hope that this issue provides a valuable exposé and comparison of the status and health of large ecosystems distributed across the three continents. Such comparisons are essential in providing insights into common themes (biodiversity, food web interactions, fish habitat, and fisheries), and threats (eutrophication, toxic chemicals, invasive species and climate change). They should also aid in the development of models and in application of emerging technology to improve our understanding, monitoring and management of these precious aquatic resources which face multiple stressors (Munawar, 1987; 2000; 2009).M.
