Effects of fire retardant chemical and fire suppressant foam on shrub steppe vegetation in northern Nevada Effects of fire retardant chemical and fire suppressant foam on shrub steppe vegetation in northern Nevada
The objectives of this study were to determine the effects of fire retardantchemical (Phos-Chek G75-F*) and fire suppressant foam (Silv-Ex) application,alone and in combination with fire, on Great Basin shrub steppe vegetation. Wemeasured growth, resprouting, flowering, and incidence of galling insects onChrysothamnus viscidiflorusandArtemisia tridentata. These characteristics were...

Uncommon breeding birds in North Dakota: Population estimates and frequencies of occurrence Uncommon breeding birds in North Dakota: Population estimates and frequencies of occurrence
Breeding bird populations were surveyed on 128 randomly selected quarter-sections throughout North Dakota in 1967, 1992, and 1993. Population estimates and frequencies of occurrence are reported for 92 uncommon breeding bird species with statewide frequencies of less than 10%.

Twenty-year home-range dynamics of a white-tailed deer matriline Twenty-year home-range dynamics of a white-tailed deer matriline
We examined the seasonal migration and home-range dynamics of a multigeneration white-tailed deer (Odocoileus virginianus) matriline comprising six females from four generations spanning a 20-year period in northeastern Minnesota. All, from the matriarch to her great-granddaughter, migrated to the same summer and winter ranges, the longest individual record being 14.5 years. Three...

Effects of management practices on grassland birds: Lark Sparrow Effects of management practices on grassland birds: Lark Sparrow
Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated...

Foods of American badgers in west-central Minnesota and southeastern North Dakota during the duck nesting season Foods of American badgers in west-central Minnesota and southeastern North Dakota during the duck nesting season
Although the American badger (Taxidea taxus) is common in grasslands and preys on a wide diversity of foods including birds, little is known about badger diet in areas where nesting ducks are common. Small mammals, primarily Muridae and Geomyidae, were the most common food items in the diet of badgers collected from west-central Minnesota and southeastern North Dakota during April-July...

The insignificance of statistical significance testing The insignificance of statistical significance testing
Despite their use in scientific journals such as The Journal of Wildlife Management, statistical hypothesis tests add very little value to the products of research. Indeed, they frequently confuse the interpretation of data. This paper describes how statistical hypothesis tests are often viewed, and then contrasts that interpretation with the correct one. I discuss the arbitrariness of P...

Wood duck brood movements and habitat use on prairie rivers in South Dakota Wood duck brood movements and habitat use on prairie rivers in South Dakota
Wood duck (Aix sponsa) populations have been increasing in the Central Flyway, but little is known about wood duck brood rearing in prairie ecosystems. We compared movements and habitat use of radiomarked female wood ducks with broods in South Dakota on 2 rivers with contrasting prairie landscapes. The perennial Big Sioux River had a broad floodplain and riparian forest, whereas the...

Survival of postfledging mallards in northcentral Minnesota Survival of postfledging mallards in northcentral Minnesota
Effective, economical management of waterfowl populations requires an understanding of age-, sex-, and cause-specific forces of mortality. We used radio telemetry to estimate survival rates of immature mallards (Anas platyrhynchos) from fledging to autumn migration in northcentral Minnesota. We monitored 48 females and 42 males during 1972-74 and observed 31 deaths during 2,984 exposure...
