Summary

Description

The objectives of the aquatic ecology study include an assessment of the fish and aquatic invertebrate populations in the streams and in the ponds throughout the entire year. Most of the work which was to be done on these populations was to be accomplished during the productive or summer months; however, it was necessary to establish observations on these populations during the winter periods. Accordingly, a trip was made in December, 1967, and one in March, 1968, during which both the fish and invertebrate populations were sampled and examined for seasonal variation in terms of both species and numbers.

Summary

Description

From 6 to 26 June, six biologists made 231 observations of geese. Of this number, 43 were banded, 74 unbanded, and 114 undiscernible. From these observations it is estimated that Agattu island has a minimum Aleutian Canada goose population of 52 individuals. Eleven Aleutian Canada goose nests and one brood pair were located. A viable population of Aleutian Canada geese has been established on Agattu through transplanting birds from Buldir. The recolonization of Agattu Island by Aleutian Canada geese has been firmly established, bringing the subspecies one step closer to removal from the endangered species list.

Summary

Description

Mallard ducks fed 0.25, 1.0, 2.5, 3.0, or 5.0 percent South Louisiana crude oil exhibited decreases in egg production, fertility, and hatchability in proportion to the concentration of oil. Extremely low amounts of petroleum hydrocarbons were also toxic to fertile, incubating mallard eggs. Our data suggests that adult waterfowl may be able to adapt and tolerate high concentrations of ingested petroleum hydrocarbons, but that all phases of reproduction and early development are severely impaired by low concentrations of petroleum hydrocarbons.

Summary

Description

Six alternatives are presently being studied by the Corps of Engineers, in conjunction with facilitating construction of a bottomfish harbor at Akutan Harbor located on Akutan Island in the Aleutian Islands. The alternatives represent a variety of engineering designs in a variety of topographic areas. Even though the environmental impacts for each alternative fall into similar categories, the extent and magnitude of concern will vary between them; therefore, we have preliminarily determined that the Akutan Point alternative is the least environmentally acceptable site and should be avoided. The Head of Bay alternative is also classified as least environmentally acceptable but to a lesser degree than Akutan Point. Those alternatives more environmentally acceptable for project construction include Salthouse Cove, South Beach, Whaling Station, and MidHarbor North and South.

Summary

Description

Sandhill cranes have been recorded on Alaska breeding pair surveys since 1957. Observations have been expanded for area only providing mean indexes of 2,200 for sprucemuskeg habitat, 26,500 for tundra habitat, and 28,800 for Alaska. These indexes have been further expanded with postulated visibility correction factors for respective habitats yielding mean populations of 23,100 for sprucemuskeg, 98,100 for tundra, and 121,700 for Alaska. Significant positive correlations r .22, p .01 for indexes; r 2 .27, p .01 for visibility corrected indexes result when breeding pair survey data is compared with Nebraska sandhill crane spring migration counts. The value of survey results could be increased with additional effort. The data shows an increase in the Alaska sandhill crane breeding population 195780, a 24 year period of consistent standard aerial waterfowl survey effort.
