High duck nesting success in a predator-reduced environment High duck nesting success in a predator-reduced environment

Duck nesting and production were studied during 1969-74 on a 51-ha field of undisturbed grass-legume cover and a surrounding 8.13-km2 area in north-central South Dakota. The principal mammalian predators of ducks were reduced within a 259-km2 zone from May 1969 through August 1971. Dabbling duck nest densities, hatching success, and breeding populations attained high levels. Seven duck...

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...

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...
