Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)
Back-yard banding above the Patuxent River gorge was limited to early mornings and evenings on 28 days from 20 August through 12 October, and four full days within the same period.Although the number of birds captured per 100 net-hours was well above average in each of the three months, the only species banded in unusually high numbers was the Gray Catbird (68 birds vs. 61, 39, and 32 in 1973, 197

New potassium-argon data on the age of mineralization and metamorphism in the Willow Creek mining district, southern Talkeetna Mountains, Alaska
The now largely abandoned Willow Creek mining district, southern Talkeetna Mountains, Alaska, produced nearly $18,000,000 in gold and minor silver between 1909 and the early 1950's. Mineralized quartz veins, which contain gold and silver along with minor quantities of base metals (in pyrite, galena, chalcopyrite, sphalerite, molybdenite, and arsenopyrite), cut Late Cretaceous and early Tertiary to

New ages on intrusive rocks and altered zones in the Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1977
Preliminary potassium-argon dating of intrusive rocks and altered zones in the Chignik and Sutwik Island quadrangles of the Alaska Peninsula seems to indicate at least three and possibly four Tertiary ages of alteration and mineralization.

Effects of dietary addition of vitamins C and D3 on growth and calcium and phosphorus content of pond-cultured channel catfish
Fingerling channel catfish, Ictalurus punctatus, were fed one of three diets: one deficient in vitamin C (ascorbic acid), one deficient in vitamin D3 (cholecalciferol), or one containing both vitamins. Semimonthly from May to September and monthly from September to February, calcium and phosphorus were determined in eviscerated bodies and fat-free skeletons by neutron activation analysis. Body wei

The United States Geological Survey in Alaska: Accomplishments during 1977
United States Geological Survey projects in Alaska study a wide range of topics of economic and scientific interest. Work done in 1977 includes contributions to economic geology, regional geology, stratigraphy, engineering geology, hydrology, and marine geology. Many maps and reports covering various aspects of the geology and mineral and water resources of the State were published. In addition, t
Impacts of transmission lines on birds in flight: Proceedings of a workshop
Progress to alleviate the national and world energy problem will come as individual issues are identified and acceptable solutions implemented. One of the specific issues to emerge in the last few years in the United States is the impact of electric power transmission lines on birds in flight. Therefore, the National Power Plant Team, Office of Biological Services, U.S. Fish and Wildlife Service,
