Lakes are key components of biogeochemical and ecological processes, thus knowledge about their distribution, volume and residence time is crucial in understanding their properties and interactions within the Earth system. However, global information is scarce and inconsistent across spatial scales and regions. Here we develop a geo-statistical model to estimate the volume of global lakes with ...

In the recent several decades, glacial lakes have been expanding at the terminus of debris-covered glaciers associated with glacier shrinkage in the Himalayas. Accordingly, glacial lake outburst floods (GLOFs) have become serious natural disasters in the Himalayas. Bathymetrical surveys have been carried out at several glacial lakes, and the relationship between the lake area and water volume h...

We explored the Wisconsin Department of Natural Resources’ (WI DNR) fish contaminant database to determine the availability and utility of historical (1970 2002) Hg records for different species and to identify lakes with historical Hg data. Walleye skin-on fillets were selected for further examination. This project supported processing and characterization of 310 additional walleyes from 36 la...

The Aquatic Macrophyte Community Index (AMCI) is a multipurpose tool developed to assess the biological quality of aquatic plant communities in lakes. It can be used to specifically analyze aquatic plant communities or as part of a multimetric system to assess overall lake quality for regulatory, planning, management, educational, or research purposes. The components of the index are maximum de...

Solar ultraviolet radiation (UVR, 290-400 nm) is a crucial environmental factor in alpine lakes because of the natural increase of the UVR flux with elevation and the high water transparency of these ecosystems. The ecological importance of UVR, however, has only recently been recognized. This review, examines the general features of alpine lakes regarding UVR, summarizes what is known about th...

Competition for shared resources is typically invoked as the most important ecological interaction promoting diversification and speciation, whereas the roles of abiotic variables and natural enemies have been largely neglected. To improve our understanding of the ecological factors involved in the evolution of sympatric stickleback species pairs (Gasterosteus aculeatus), I examined whether lak...

The Great Lakes constitute the largest body of surface freshwater on earth and are one of the planet's most valuable natural resources. Home to roughly 36 million people, the Great Lakes basin is a major industrial and agricultural region of North America. The Canadian portion of the basin contains one-third of the Canadian population and half of all the manufacturing activity in Canada. The he...
