1992, Journal of Wildlife Management (56) 337-343
Response rates to the Federal Waterfowl Hunter Questionnaire Survey (WHQS) have declined since the 1950's, suggesting that harvest estimates may be biased. Consequently, we investigated reasons for WHQS nonresponse using surveys of waterfowl hunters in Arkansas, California, Louisiana, Minnesota, New Jersey, and Texas. Sampling frames were constructed using lists of...

Response of regional seismicity to the static stress change produced by the Loma Prieta earthquake
P.A. Reasenberg, R.W. Simpson
1992, Science (255) 1687-1690
The 1989 Loma Prieta, California, earthquake perturbed the static stress field over a large area of central California. The pattern of stress changes on major faults in the region predicted by models of the earthquake's dislocation agrees closely with changes in the regional seismicity rate after the earthquake. The agreement...

Gravity-driven groundwater flow and slope failure potential: 2. Effects of slope morphology, material properties, and hydraulic heterogeneity
Mark E. Reid, Richard M. Iverson
1992, Water Resources Research (28) 939-950
Hillslope morphology, material properties, and hydraulic heterogeneities influence the role of groundwater flow in provoking slope instability. We evaluate these influences quantitatively by employing the elastic effective stress model and Coulomb failure potential concept described in our companion paper (Iverson and Reid, this issue). Sensitivity analyses show that of four...

Gravity-driven groundwater flow and slope failure potential: 1. Elastic effective-stress model
Richard M. Iverson, Mark E. Reid
1992, Water Resources Research (28) 925-938
Hilly or mountainous topography influences gravity-driven groundwater flow and the consequent distribution of effective stress in shallow subsurface environments. Effective stress, in turn, influences the potential for slope failure. To evaluate these influences, we formulate a two-dimensional, steady state, poroelastic model. The governing equations incorporate groundwater effects as body forces,...

M.B. Kruger, Raymond Jeanloz, M.P. Pasternak, R. D. Taylor, B.S. Snyder, A.M. Stacy, S.R. Bohlen
1992, Science (255) 703-705
Amorphous Fe2SiO4 synthesized at elevated pressures exhibits a Néel transition at a temperature identical to that observed in the crystalline form, TN = 65 (±2) kelvin at zero pressure. This behavior contrasts sharply with observations on other disordered systems, such as spin glasses, which characteristically exhibit strong "frustration" of the spins and consequent...
Estimating transition probabilities for stage-based population projection matrices using capture-recapture data
James D. Nichols, John R. Sauer, Kenneth H. Pollock, Jay B. Hestbeck
1992, Ecology (73) 306-312
In stage—based demography, animals are often categorized into size (or mass) classes, and size—based probabilities of surviving and changing mass classes must be estimated before demographic analyses can be conducted. In this paper, we develop two procedures for the estimation of mass transition probabilities from capture—recapture data. The first approach...
