Evaluation of some random effects methodology applicable to bird ringing data
K.P. Burnham, Gary C. White
2002, Journal of Applied Statistics (29) 245-264
Existing models for ring recovery and recapture data analysis treat temporal variations in annual survival probability (S) as fixed effects. Often there is no explainable structure to the temporal variation in S1,..., Sk; random effects can then be a useful model: Si = E(S) + ??i. Here, the temporal variation...
Regional fluid flow as a factor in the thermal history of the Illinois basin: Constraints from fluid inclusions and the maturity of Pennsylvanian coals
E. L. Rowan, M. B. Goldhaber, J. R. Hatch
2002, American Association of Petroleum Geologists Bulletin (86) 257-277
Vitrinite reflectance measurements on Pennsylvanian coals in the Illinois basin indicate significantly higher thermal maturity than can be explained by present-day burial depths. An interval of additional sedimentary section, now removed by erosion, has been suggested to account for the discrepancy. Although burial could indeed account for the observed maturity...
Syntectonic remagnetization in the southern Methow block: Resolving large displacements in the southern Canadian Cordillera
Randolph J. Enkin, J. B. Mahoney, J. Baker, M. Kiessling, Ralph Haugerud
2002, Tectonics (21) 18-1-18-18
The Upper Cretaceous Ventura Member of the Goat Wall unit in the southern Methow block of southern British Columbia and northern Washington State holds a syntectonic magnetization. Eight new sites from Manning Park in British Columbia give a mean direction of D = 27.5°, I = 60.1°, k = 304.7, α95 = 3.2° after optimal partial tilt...
Estimating recharge at Yucca Mountain, Nevada, USA: Comparison of methods
A. L. Flint, L. E. Flint, E. M. Kwicklis, J. T. Fabryka-Martin, G.S. Bodvarsson
2002, Hydrogeology Journal (10) 180-204
Obtaining values of net infiltration, groundwater travel time, and recharge is necessary at the Yucca Mountain site, Nevada, USA, in order to evaluate the expected performance of a potential repository as a containment system for high-level radioactive waste. However, the geologic complexities of this site, its low precipitation and net...
Sustainability of vegetation communities grazed by elk in Rocky Mountain National Park
K.A. Schoenecker, F. J. Singer, Romulo S.C. Menezes, L. C. Zeigenfuss, Dan Binkley
Francis J. Singer, Linda Zeigenfuss, editor(s)
2002, Report, Ecological evaluation of the abundance and effects of elk herbivory in Rocky Mountain National Park, Colorado, 1994-1999 (Open File Report 2002-208)
Current management of the worlds' grazing lands in either based on changes in plant species composition or on other management evaluation programs that emphasize changes in net aboveground production. Management is based solely on changes in aboveground production has been criticized as too limited in view, because it ignores root...
Life history attributes of fishes along the latitudinal gradient of the Missouri River
P.J. Braaten, C.S. Guy
2002, Transactions of the American Fisheries Society (131) 931-945
Populations of two short-lived species (emerald shiner Notropis atherinoides and sicklefin chub Macrhybopsis meeki) and three long-lived species (freshwater drum Aplodinotus grunniens, river carpsucker Carpiodes carpio, and sauger Stizostedion canadense) were studied in the Missouri River to examine spatial variations in life history characteristics across a latitudinal and thermal gradient...
Evaluating remedial alternatives for an acid mine drainage stream: Application of a reactive transport model
R.L. Runkel, B. A. Kimball
2002, Environmental Science & Technology (36) 1093-1101
A reactive transport model based on one-dimensional transport and equilibrium chemistry is applied to synoptic data from an acid mine drainage stream. Model inputs include streamflow estimates based on tracer dilution, inflow chemistry based on synoptic sampling, and equilibrium constants describing acid/base, complexation, precipitation/dissolution, and sorption reactions....
Leisingera methylohalidivorans gen. nov., sp. nov., a marine methylotroph that grows on methyl bromide
J.K. Schaefer, K.D. Goodwin, I.R. McDonald, J.C. Murrell, Ronald S. Oremland
2002, International Journal of Systematic and Evolutionary Microbiology (52) 851-859
A marine methylotroph, designated strain MB2T, was isolated for its ability to grow on methyl bromide as a sole carbon and energy source. Methyl chloride and methyl iodide also supported growth, as did methionine and glycine betaine. A limited amount of growth was observed with dimethyl sulfide. Growth was also...
How stakeholder roles, power, and negotiation impact natural resource policy: A political economy view
L. Caughlan
2002, Thesis
Natural resource management decisions are complicated by multiple property rights, management objectives, and stakeholders with varying degrees of influence over the decision making process. In order to make efficient decisions, managers must incorporate the opinions and values of the involved stakeholders as well as understand the complex institutional constraints and...
Climate variability from the Florida Bay sedimentary record: Possible teleconnections to ENSO, PNA and CNP
T. M. Cronin, Gary S. Dwyer, S.B. Schwede, C.D. Vann, H. Dowsett
2002, Climate Research (19) 233-245
We analyzed decadal and interannual climate variability in South Florida since 1880 using geochemical and faunal paleosalinity indicators from isotopically dated sediment cores at Russell Bank in Florida Bay (FB). Using the relative abundance of 2 ostracode species and the Mg/Ca ratios in Loxoconcha matagordensis shells to reconstruct paleosalinity, we...
Energy budget above a high-elevation subalpine forest in complex topography
A.A. Turnipseed, P.D. Blanken, D.E. Anderson, Russell K. Monson
2002, Agricultural and Forest Meteorology (110) 177-201
Components of the energy budget were measured above a subalpine coniferous forest over two complete annual cycles. Sensible and latent heat fluxes were measured by eddy covariance. Bowen ratios ranged from 0.7 to 2.5 in the summer (June–September) depending upon the availability of soil...
