Assessing the tolerance of fish and fish populations to environmental stress: The problems and methods of monitoring Assessing the tolerance of fish and fish populations to environmental stress: The problems and methods of monitoring
Environmental stress is an inescapable aspect of life in the aquatic environment. The chemical and physical demands of life underwater impose somewhat rigorous constraints on aquatic species (Smith, 1982a). Superimposed on such demands may be the additional. physiological constraints of particular ecological niches. It is true that aquatic species are adapted to these conditions, but...

Craggy Mountain Wilderness Study Area and Extension, North Carolina Craggy Mountain Wilderness Study Area and Extension, North Carolina
Craggy Mountain Wilderness Study Area and the adjoining Craggy Mountain Extension consist of more than 4 sq mi of steep wooded slopes on the west side of Great Craggy Mountain in the Blue Ridge of western North Carolina. A mineral-resource survey of the area done between 1976 and 1979 found no evidence fore metallic mineral resources. Kyanite, garnet, and building stone are the only...

Crassulacean acid metabolism in submerged aquatic plants Crassulacean acid metabolism in submerged aquatic plants
CO2-fixation in the dark is known to occur in various organs of many plants. However, only in species possessing crassulacean acid metabolism (CAM) does dark CO2-fixation contribute substantially to the carbon economy of the plant. Until very recently CAM was known only from terrestrial species, largely drought adapted succulents. The discovery of CAM in the submerged aquatic fern ally...
