A point-intercept survey was implemented in August 2000 to determine the distribution and richness of aquatic plant species present in Waneta Lake and Lamoka Lake, NY. Myriophyllum spicatum (Eurasian watermilfoil) was the most commonly observed species in Waneta Lake (25% of entire lake, 78% of littoral zone) and Lamoka Lake (43% of entire lake, 77% of littoral zone). Eurasian watermilfoil biom...

We examined patterns of non-native plant diversity in protected and managed ponderosa pine/Douglas-®r forests of the Colorado Front Range. Cheesman Lake, a protected landscape, and Turkey Creek, a managed landscape, appear to have had similar natural disturbance histories prior to European settlement and ®re protection during the last century. However, Turkey Creek has experienced logging, graz...

both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the imandra lake (the largest subarctic lake at kola peninsula, russia) were investigated during the 1990 - 2003 period. we used different indexes of solar activity (sunspot numbers and uv- radiation values) as heliophysical factors. information about uv- radiation values was derived from satellite...

The current study deals with the physicochemical characterization, temporal variability and trophic state evaluation of a post glacial mountain lake in eastern Himalaya during the period of 2014-2016. Notable seasonal variations are recorded for physicochemical parameters of lake water. The values for electrical conductivity, total suspended solids, total dissolved solids, total alkalinity and ...

—Populations of lake trout Salvelinus namaycush in Lake Superior collapsed in the late 1950s due to overfishing and predation by sea lampreys Petromyzon marinus. A binational effort to restore the lean morphotype of lake trout began with the stocking of hatchery-reared fish followed by the chemical control of sea lampreys and closure of the commercial fishery. Previous comparisons of the contem...
