Geochemistry of Arsenic, Manganese, and Iron in the Dexter Pit Lake, Tuscarora, Nevada
The Dexter pit lake is a mine pit lake located in north-eastern Nevada, located in the Tuscarora volcanic field. The pit lake formed in 1990 following cessation of open-pit gold and silver mining operations. This pit lake has been the subject of previous geological study, which served to outline …

Comparison of Creel Survey Data to Traditional Sampling Techniques in Pit-Lake Fisheries of Muhlenberg County, Kentucky
… macrochirus</em>, were evaluated from five pit-lakes in Muhlenberg County, Kentucky, to determine if accurate proportional stock density (PSD) data can be obtained from a mandatory creel survey. It was hypothesized that the proportion of stock-to-quality (300-400mm) and quality (+400mm) …

Relationships between population density feeding and growth of the roach (Ratilus ratilus, L. 1758) and other coarse fish in a gravel-pit lake in Southern England
Gravel-pit lakes are an increasingly common feature of our landscape, particularly on the flood plains of rivers close to large urban or industrial areas e. g. the Thames Valley (see Fig. 1). When sand and gravel are removed from below the water table, lakes are produced by seepage into the …

Identifying Optimal Sites for Aquaculture in Southern Ontario Aggregate Pit Lakes: A Sustainable Post-Mining Land-Use Alternative
… the water table. As these sites transition into pit lakes, they are often characterized by low nutrients, steep walls, and limited biological activity. These future pit lakes represent a unique opportunity for repurposing to create positive social and economic impacts. However, effective …

The role of aquatic macrophytes in the availability of food for young fish
Quantitative samples from a gravel-pit lake in 1977 (April-December) showed higher geometric mean densities and biomasses of microcrustacea in the marginal weedbeds (907/1 and 3107ug/l) than in the open water (225/1 and 245ug/l). The weedbeds were dominated by Cyclops vernalis americanus and …

Part A: Studies Towards Total Synthesis of an Anticancer and Antifungal Natural Product, Pseudolaric Acid B; Part B: Synthesis and Biological Evaluation of Berkeleyamide a and Its Derivatives
… evolved in extreme ecosystems such as a Berkeley Pit Lake in search of potential anticancer and antimicrobial agents. One such natural product, Berkeleyamide A, isolated from the fungi Pencillium rubrum, inhibited caspase-1 (ICE) and the signal transducing enzyme matrix metalloproteinase-3 (MMP-3) …
