Biochemical identification of mallard-black duck hybrids through a breeding program and in nature Biochemical identification of mallard-black duck hybrids through a breeding program and in nature
From 1974 to 1976, a breeding program was used to produce black duck-mallard hybrids for the evaluation of inheritance patterns of serum proteins and esterases. In addition to the initial crosses, a series of matings in 1975 and 1976 were designed to evaluate inheritance patterns in hybrid matings with either black duck or mallards. At the F1 level, hybrids were easily distinguished...

Habitat use by prairie raccoons during the waterfowl breeding season Habitat use by prairie raccoons during the waterfowl breeding season
Mobility and habitat use of raccoons (Procyon lotor) in an intensively farmed area of the prairie pothole region were studied during the waterfowl breeding seasons (April-July) of 1973-75. Over 5700 locations of 30 raccoons were analyzed. Movement patterns varied with sex, age, and reproductive status. Adult males moved regularly throughout slightly overlapping ranges that averaged 2560...

Changes in submerged aquatic macrophyte populations at the head of Chesapeake Bay, 1958-1975 Changes in submerged aquatic macrophyte populations at the head of Chesapeake Bay, 1958-1975
Submerged aquatic plant populations in the Susquehanna Flats of the Chesapeake Bay were followed for 18 years. An exotic species, eurasian water milfoil, Myriophyllum spicatum, increased dramatically from 1958 to 1962; at the same time the dominant native species declined. After 1962, milfoil populations declined and the native rooted aquatics gradually began to return to their former...

Leech parasitism of waterfowl in North America Leech parasitism of waterfowl in North America
Leech parasitism of waterfowl is widespread in North America. Twenty species of ducks, geese, and swans have been infested by leeches, particularly Theromyzon rude and Placobdella ornata. Sites of attachment include the eyes, nasal passages, and body. Information is lacking on the biology and ecology of duck leeches. Their significance as morbidity and mortality factors and their...

Post-breeding activities of mallards and wood ducks in north-central Minnesota Post-breeding activities of mallards and wood ducks in north-central Minnesota
We used radio telemetry to monitor the post-breeding activities of 129 mallards (Anas platyrhynchos) and 118 wood ducks (Aix sponsa) on a 932-km2 area in north-central Minnesota from 1968 to 1974. Upon completion of breeding activities and before the flightless period, all mallard drakes departed the area; this exodus peaked during early June. Of the non-brood hens 8 of 23 remained on...

Duck nesting in intensively farmed areas of North Dakota Duck nesting in intensively farmed areas of North Dakota
A study to determine the major factors limiting duck nesting and production on intensively farmed areas in eastern North Dakota was conducted from 1969 through 1974. A total of 186 duck nests was found during searches on 6,018 ha of upland. Nest density per km2 for 5 major habitat types was 20.2 in untilled upland, 3.7 in standing grain stubble, 1.6 in mulched grain stubble, 1.2 in...

Some Bayesian statistical techniques useful in estimating frequency and density Some Bayesian statistical techniques useful in estimating frequency and density
This paper presents some elementary applications of Bayesian statistics to problems faced by wildlife biologists. Bayesian confidence limits for frequency of occurrence are shown to be generally superior to classical confidence limits. Population density can be estimated from frequency data if the species is sparsely distributed relative to the size of the sample plot. For other...

Analysis and machine mapping of the distribution of band recoveries Analysis and machine mapping of the distribution of band recoveries
A method of calculating distance and bearing from banding site to recovery location based on the solution of a spherical triangle is presented. X and Y distances on an ordinate grid were applied to computer plotting of recoveries on a map. The advantages and disadvantages of tables of recoveries by State or degree block, axial lines, and distance of recovery from banding site for...
