Type specimens and basic principles of avian taxonomy Type specimens and basic principles of avian taxonomy
"Ornithology" may be defined as the scientific study of birds. No aspect of avian biology, including management and conservation, can be carried out without reference by name to birds at some taxonomic level. Thus, the names of species of birds, and of groups of species, can fairly be considered to be of primary importance in ornithology. To be useful, these names themselves must be...

Down-regulation of muscarinic receptors and the m3 subtype in white-footed mice by dietary exposure to parathion Down-regulation of muscarinic receptors and the m3 subtype in white-footed mice by dietary exposure to parathion
The effect of ad libitum dietary exposure (as occurs in the field) to parathion for 14 d was investigated on the muscarinic acetylcholine receptor (mAChR) in brains and submaxillary glands of adults of a field species, the white-footed mouse Peromyscus leucopus. Immunoprecipitation using subtype selective antibodies revealed that the relative ratios of the m1-m5 mAChR subtypes in...

Campsite impact management: A survey of National Park Service backcountry managers Campsite impact management: A survey of National Park Service backcountry managers
Though a central purpose for the creation and management of parks, visitation inevitably affects the natural resources of parks. This is particularly true at campsites, where visitation and its effects are concentrated. This paper presents partial results from a survey of National Park Service managers regarding general strategies and specific actions implemented by park managers to...

Estimating survival of radio-tagged birds Estimating survival of radio-tagged birds
Parametric and nonparametric methods for estimating survival of radio-tagged birds are described. The general assumptions of these methods are reviewed. An estimate based on the assumption of constant survival throughout the period is emphasized in the overview of parametric methods. Two nonparametric methods, the Kaplan-Meier estimate of the survival funcrion and the log rank test, are...

Population trends of quails in North America Population trends of quails in North America
We used North American Breeding Bird Survey data (1966-91) to estimate distribution, relative abundance, and populatiori trends of quails. Population trends in grassland/shrub birds sympatric with northern bobwhite (Colinus virginianus) were also examined. Northern bobwhite and scaled quail (Callipepla squamata) populations have declined since 1966. Rates of decline for these quails have

Prey escaping wolves, Canis lupus, despite close proximity Prey escaping wolves, Canis lupus, despite close proximity
We describe attacks by wolf (Canis lupus) packs in Minnesota on a white-tailed deer (Odocoileus virginianus) and a moose (Alces alces) in which wolves were within contact distance of the prey but in which the prey escaped.
