1992, Journal of Wildlife Diseases (28) 91-94
Resting metabolic rates, weight gains and hematologic profiles of six newborn, captive white-tailed deer (Odocoileus virginianus) fawns (four females, two males) were determined during the first 3 mo of life. Estimated mean daily weight gain of fawns was 0.2 kg. The regression equation...
A study of the genetic relationships within and among wolf packs using DNA fingerprinting and mitochondrial DNA
Niles Lehman, Peter Clarkson, L. David Mech, Thomas J. Meier, Robert K. Wayne
1992, Behavioral Ecology and Sociobiology (30) 83-94
DNA fingerprinting and mitochondrial DNA analyses have not been used in combination to study relatedness in natural populations. We present an approach that involves defining the mean fingerprint similarities among individuals thought to be unrelated because they have different mtDNA genotypes. Two classes of related individuals are identified by their...
Assessing effects of pesticides on amphibians and reptiles: status and needs
R.J. Hall, P.F.P. Henry
1992, Herpetological Journal (2) 65-71
Growing concern about the decline of certain amphibian populations and for conservation of amphibians and reptiles has led to renewed awareness of problems from pesticides. Testing amphibians and reptiles as a requirement for chemical registration has been proposed but is difficult because of the phylogenetic diversity of these groups....
The relationship between annual survival rate and migration distance in mallards: An examination of the time-allocation hypothesis for the evolution of migration
J.B. Hestbeck, J.D. Nichols, J.E. Hines
1992, Canadian Journal of Zoology (70) 2021-2027
Predictions of the time-allocation hypothesis were tested with several a posteriori analyses of banding data for the mallard (Anas platyrhynchos). The time-allocation hypothesis states that the critical difference between resident and migrant birds is their allocation of time to reproduction on the breeding grounds and survival on the nonbreeding...
Winter habitat occurrence patterns of temperate migrant birds in Belize
D.K. Dawson, C.S. Robbins, J.R. Sauer
1992, El Pitirre (Society of Caribbean Ornithology) (5) 3-4
We used mist nets and point counts to sample bird populations in 61 sites in Belize during January-March of 1987-1991. Sites were classified as forest, second growth, woody agricultural crops (citrus, mango, cacao, and cashew), or non-woody agricultural crops (rice and sugar cane). We evaluated patterns of occurrence of wintering...
An evaluation of regression methods to estimate nutritional condition of canvasbacks and other water birds
D. W. Sparling, J.A. Barzen, J.R. Lovvorn, J.R. Serie
1992, Biological Report 3
Regression equations that use mensural data to estimate body condition have been developed for several water birds. These equations often have been based on data that represent different sexes, age classes, or seasons, without being adequately tested for intergroup differences. We used proximate carcass analysis of 538 adult...
Modeling metapopulation dynamics for single species of seabirds
P. A. Buckley, R. Downer
D.R. McCullough, R.H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations
Seabirds share many characteristics setting them apart from other birds. Importantly, they breed more or less obligatorily in local clusters of colonies that can move regularly from site to site, and they routinely exchange breeders. The properties of such metapopulations have only recently begun to be examined, often with...
Relating results from earthworm toxicity tests to agricultural soil
W. N. Beyer
P.W. Greig-Smith, editor(s)
1992, Book chapter, Ecotoxicology of Earthworms
The artificial soil tests of the European Economic Community and of the Organization for Economic Cooperation produce data relating earthworm mortality to pesticide concentrations in soil under laboratory conditions. To apply these results to agricultural soils it is necessary to relate these concentrations to amounts of pesticide applied per area....

Modelling population change from time series data
R. J. Barker, J.R. Sauer
D.R. McCullough, R.H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations
Information on change in population size over time is among the most basic inputs for population management. Unfortunately, population changes are generally difficult to identify, and once identified difficult to explain. Sources of variald (patterns) in population data include: changes in environment that affect carrying capaciyy and produce...
Geographic patterns in population trends of neotropical migrants in North America
J.R. Sauer, Sam Droege
John M. Hagan III, D.W. Johnston, editor(s)
1992, Book chapter, Ecology and Conservation of Neotropical Migrant Landbirds
We use the route-regression method to estimate the population trends of 100 species of Neotropical migrants using data from the North American Breeding Bird Survey (BBS). We examine long-term (1966-1988) and recent (1978-1988) trends. In the long-term, more species of Neotropical migrants were increasing than were decreasing in...
Black duck population units as determined by patterns of band recovery
G.W. Pendleton, J.R. Sauer
D.R. McCullough, R.H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations.
To estimate regional survival and band recovery rates for waterfowl populations, banding sites must be grouped for data analysis. We group American black duck banding sites using cluster analysis of pairwise comparisons of the distributions of band recoveries. We propose 6 population units, substantially fewer than the 27 black duck...
Population models for passerine birds: structure, parameterization, and analysis
B.R. Noon, J.R. Sauer
D.R. McCullough, R.H. Barrett, editor(s)
1992, Book chapter, Wildlife 2001: Populations.
Population models have great potential as management tools, as they use infonnation about the life history of a species to summarize estimates of fecundity and survival into a description of population change. Models provide a framework for projecting future populations, determining the effects of management decisions on future population dynamics,...

The extent of temporal smearing in surface-temperature histories derived from borehole temperature measurements
G.D. Clow
1992, Palaeogeography, Palaeoclimatology, Palaeoecology (98) 81-86
The ability of borehole temperature data to resolve past climatic events is investigated using Backus-Gilbert inversion methods. Two experimental approaches are considered: (1) the data consist of a single borehole temperature profile, and (2) the data consist of climatically-induced temperature transients measured within a borehole during a monitoring experiment. The...

P.R. Whitney
1992, Precambrian Research (57) 1-19
Granitic rocks in the west-central Adirondack Highlands of New York State include both relatively homogeneous charnockitic and hornblende granitic gneisses (CG), that occur in thick stratiform bodies and elliptical domes, and heterogeneous leucogneisses (LG), that commonly are interlayered with metasedimentary rocks. Major- and trace-element geochemical analyses were obtained for 115...
Distribution and characteristics of a Middle Ordovician oolitic ironstone in northeastern Kansas based on petrographic and petrophysical properties: A Laurasian ironstone case study
P. Berendsen, J.H. Doveton, S. Speczik
1992, Sedimentary Geology (76) 207-219
The margins of Gondwana are generally considered to be the major sites of oolitic ironstone production during the Ordovician, and appear to be linked with global eustatic sea-level rise. Occurrences of oolitic ironstones within the North American craton are less well documented, but provide important supplementary data. The low latitude...
The nature of Archean terrane boundaries: An example from the northern Wyoming Province
D.W. Mogk, P.A. Mueller, J. L. Wooden
1992, Precambrian Research (55) 155-168
The Archean northern Wyoming Province can be subdivided into two geologically distinct terranes, the Beartooth-Bighorn magmatic terrane (BBMT) and the Montana metasedimentary terrane (MMT). The BBMT is characterized by voluminous Late Archean (2.90-2.74 Ga) magmatic rocks (primarily tonalite, trondhjemite, and granite); metasedimentary rocks are preserved only as small, rare enclaves...
Spectral ratio method for measuring emissivity
K. Watson
1992, Remote Sensing of Environment (42) 113-116
The spectral ratio method is based on the concept that although the spectral radiances are very sensitive to small changes in temperature the ratios are not. Only an approximate estimate of temperature is required thus, for example, we can determine the emissivity ratio to an accuracy of 1% with a...
