The comparison of usage and availability measurements for evaluating resource preference The comparison of usage and availability measurements for evaluating resource preference

Modern ecological research often involves the comparison of the usage of habitat types or food items to the availability of those resources to the animal. Widely used methods of determining preference from measurements of usage and availability depend critically on the array of components that the researcher, often with a degree of arbitrariness, deems available to the animal. This paper...

Enumeration of prairie wetlands with Landsat and aircraft data Enumeration of prairie wetlands with Landsat and aircraft data

A method is described for making an estimate of wetland numbers in the glaciated prairie region. A double-phase sampling approach is used which consists of first making a total census of wetlands using Landsat data, and then adjusting the Landsat results on the basis of samples derived from high resolution aircraft data. The method is relatively simple to use and has general...

Lead residues in sora rails from Maryland Lead residues in sora rails from Maryland

During September and October, mi- grating sora rails (Porzana carolina) use tidal marshes of the Patuxent River in Maryland, where they have been hunted for many years. Spent shot accumulates in the marsh during the rail hunting sea- son, and some shot is ingested by the birds. Twelve percent of gizzards from rails collected at the marsh during 1965- 73 contained lead shot (Artmann and...

Age determination of mallards Age determination of mallards

A technique for distinguishing adult from yearling wild mallards (Anas platyrhynchos), from late winter through the nesting season, was developed by applying discriminant analysis procedures to selected wing feather characters of 126 yearlings and 76 adults (2-year-olds) hand-reared from wild eggs during 1974, 1975, and 1977. Average values for feather characters generally increased as...

Use of prairie pothole habitat by breeding mallards Use of prairie pothole habitat by breeding mallards

Detailed information on the use by mallards (Anas platyrhynchos) of prairie pothole habitat during the nesting season is necessary to interpret habitat needs of the species during the breeding period. Many data have been collected and published relating pair counts to habitat use and water conditions (e.g., Evans and Black 1956; Smith 1971; Stoudt 1971; Stewart and Kantrud 1973, 1974)...

Modeling sandhill crane population dynamics Modeling sandhill crane population dynamics

The impact of sport hunting on the Central Flyway population of sandhill cranes (Grus canadensis) has been a subject of controversy for several years. A recent study (Buller 1979) presented new and important information on sandhill crane population dynamics. The present report is intended to incorporate that and other information into a mathematical model for the purpose of assessing the...
