Electrophoresis as a management tool Electrophoresis as a management tool
The theme of this 1974 Northeast Fish and Wildlife Conference is 'A New Era'. Indeed, it is a new era for improved techniques to assist in management of our fish and wildlife resources for the maximum benefit of all. In some cases, the new techniques are primarily used in research.on fish and wildlife, and the results from the research are used to aid management and enforcement agencies...

Progress report on the North American Breeding Bird Survey Progress report on the North American Breeding Bird Survey
The Breeding Bird Survey has been monitoring bird population changes in the U.S.A. and Canada since 1966. Each cooperator makes 50 3-minute stops at 0.8-km intervals along randomly selected roadside routes in 4 to 4 1/2 hours on one morning in June of each year. Data from the 1500 to 1600 routes are entered on magnetic tape, edited for accuracy, and then used for statistical analysis of...

The winter bird survey of central Maryland, U.S.A The winter bird survey of central Maryland, U.S.A
A method for monitoring changes in winter bird populations was tested in central Maryland in the winters of 1970, 1971 and 1972. A systematic sample of 41 transects was established to sample an area of 6150 sq. km. Each transect, located at the center of a standard 7 1/2-minute topographic map, was 8 km in length and approximately square in shape. Coverage began at local sunrise on any...

Recoveries of banded Laysan albatrosses (Diomedea immutabilis) and black-footed albatrosses (D. nigripes) Recoveries of banded Laysan albatrosses (Diomedea immutabilis) and black-footed albatrosses (D. nigripes)
Summarizes the seasonal distribution of pelagic recoveries of 324 banded Laysan Albatrosses and 399 banded Black-footed Albatrosses. Different age groups of each species concentrate in somewhat different areas, and, although range overlap between species is almost complete, each has its own distinctive seasonal distribution pattern.

An attempt to age mallards using eye lens proteins An attempt to age mallards using eye lens proteins
An analysis of insoluble protein content of eye lenses from 59 known-age mallards (Anas platyrhynchos) indicated a slight increase between 8-9 months and 7 years of age. Nearly a complete overlapping of the insoluble protein content of individuals of different ages was apparent showing that the technique cannot be used to separate adult year classes of mallards. These results are...
