Feeding ecology and energetics
Successful management of walleye and sauger populations often requires a detailed knowledge of prey resources. As with many fishes, diets of juvenile Sander spp. are often different than those of adult fish and can have important implications for growth and survival. Similarly, spatial and temporal variation in diet composition can contribute to variation in growth and production of Sander populat

Development of a bioenergetics model for age-0 American shad
Bioenergetics modeling can be used as a tool to investigate the impact of non-native age-0 American shad (Alosa sapidissima) on reservoir and estuary food webs. The model can increase our understanding of how these fish influence lower trophic levels as well as predatory fish populations that feed on juvenile salmonids. Bioenergetics modeling can be used to investigate ecological processes, evalua

Diet of juvenile and adult American shad in the Columbia River
The diet of juvenile and adult American shad Alosa sapidissima captured from various locations in the Columbia River was investigated during 2007 and 2008. Collection efforts in 2007 were restricted to fish collected from existing adult and juvenile fish collection facilities located at Bonneville Dam and to adult shad captured by angling downstream from Bonneville Dam. In 2008, we used gillnets,

Growth characteristics and otolith analysis on age-0 American shad
Otolith microstructure analysis provides useful information on the growth history of fish (Campana and Jones 1992, Bang and Gronkjaer 2005). Microstructure analysis can be used to construct the size-at-age growth trajectory of fish, determine daily growth rates, and estimate hatch date and other ecologically important life history events (Campana and Jones 1992, Tonkin et al. 2008). This kind of i

Thiaminase activity and life history investigations in American shad in the Columbia River
American shad Alosa sapidissima fry were successfully transplanted from the Atlantic to the Pacific coast in 1871 and have subsequently proliferated. The Columbia River population is in the millions, yet few investigations have been conducted to better understand their life history, population dynamics, or potential impacts on other species. In 2007 and 2008 we captured American shad from the Colu

Late quaternary climate variations reflected in Baltic Sea sediments
Late Pleistocene to Holocene climate change of the Atlantic and the northern European realm is reflected by the facies of sediments in the Baltic Sea. The sedimentary sequence have been subdivided into zones reflecting the main postglacial stages of the Baltic Sea basin development according to sediment echosounder profiling and investigating sediment cores from the central Baltic. The changes in

Porosity variability in limestone sequences
Porosity is the state of being porous, as measured by the percentage of bulk volume of a rock or soil that is occupied by space, whether isolated or connected. In hydrocarbon-bearing limestone settings, subsurface porous strata containing the oil or gas usually underlie non-porous caprock through which hydrocarbons cannot pass. In settings, subsurface freshwater aquifers beneath caprock can become

Mountain Glaciers and Ice Caps
In addition to the Greenland Ice Sheet, the Arctic contains
a diverse array of smaller glaciers ranging from small cirque
glaciers to large ice caps with areas up to 20 000 km

these glaciers cover an area of more than 400 000 km

half the global area of mountain glaciers and ice caps. Their
