Removal of toxic chemicals from water with activated carbon
Activated carbon was effective in removing fish toxicants and anesthetics from water solutions. Its capacity to adsorb 3-trifluoromethyl-4-nitrophenol (TFM), antimycin, NoxfishA? (5% rotenone), Dibrorms, juglone, MSa??222, and benzocaine ranged from 0.1 to 64 mg per gram of carbon. The adsorptive capacity (end point considered as a significant discharge) of activated carbon for removal of TFM w

Upland sandpiper nesting and management in North Dakota
Nests of 195 upland sandpipers (Bartramia longicauda) on the Missouri Coteau of North Dakota generally were well concealed by grassy vegetation which ranged from 15.4-30.8 cm in height. Nest densities ranged from 0.3 per 40.5 ha on annually tilled croplands to 6.8 per 40.5 ha on native grasslands during the second growing season after a prescribed burn. Hatching success in native grasslands varied

Plasma luteinizing hormone and the development of ovarian follicles after loss of clutch in female mallards (Anas platyrhynchos)
The plasma level of LH and the extent of development of ovarian follicles were analyzed in incubating female Mallards. In both wild and game-farm stock, incubation was associated with a significant decline in plasma levels of LH from those of laying females. Within 1 day after removal of eggs, LH levels had increased to levels indistinguishable from those of laying females. The mean diameter of th
