Spectroscopy of rocks and minerals and principles of spectroscopy
Roger N. Clark
Andrew N. Rencz, editor(s)
1999, Book chapter, Manual of remote sensing, Volume 3, Remote sensing for the earth sciences
Spectroscopy is the study of light as a function of wavelength that has been emitted, reflected or scattered from a solid, liquid, or gas. In this chapter I will primarily discuss the spectroscopy of minerals, but the principles apply to any material. No single chapter can cover this topic adequately,...

Population demographics and genetic diversity in remnant and translocated populations of sea otters
James L. Bodkin, Brenda E. Ballachey, M. A. Cronin, K.T. Scribner
1999, Conservation Biology (13) 1378-1385
The effects of small population size on genetic diversity and subsequent population recovery are theoretically predicted, but few empirical data are available to describe those relations. We use data from four remnant and three translocated sea otter ( Enhydra lutris) populations to examine relations among magnitude and duration of minimum population...
Discovery of a new Kittlitz's murrelet nest: Clues to habitat selection and nest-site fidelity
John F. Piatt, Nancy L. Naslund, Thomas I. van Pelt
1999, Northwestern Naturalist (80) 8-13
On 13 June 1993, a new Kittlitz's murrelet (Brachyramphus brevirostris) nest was discovered near Red Mountain on the Kenai Peninsula, Alaska. The nest was on a 22° slope at about 900 m elevation with a northeast aspect, and contained a 60.2 × 40.6 mm egg that weighed 49.0 g. Downy...
Maturation, fecundity, and intertidal spawning of Pacific sand lance in the northern Gulf of Alaska
Martin D. Robards, John F. Piatt, G.A. Rose
1999, Journal of Fish Biology (54) 1050-1068
Pacific sand lance Ammodytes hexapterus in Kachemak Bay, Alaska, showed no sexual dimorphism in length-to-weight (gonad-free) ratio or length-at-age relationship. Most matured in their second year, males earlier in the season than females, but females (31%) attained a higher gonadosomatic index than males (21%). Sand lance spawned intertidally once each...
Structural domains and their potential impact on recharge to intermontane-basin aquifers
G.C. Ohlmacher
1999, Environmental & Engineering Geoscience (5) 61-71
Variations in the structures exposed in structural domains associated with faults can affect the amount of ground-water recharge to fractured rock aquifers supplying intermontane-basin aquifers. In the southwestern Franklin Mountains, El Paso, Texas, an outcrop of the Ordovician Scenic Drive Formation exposes a group of structures including faults, joints, and...

Fishes in mangrove prop-root habitats of northeastern Florida Bay: Distinct assemblages across an estuarine gradient
J.A. Ley, Carole McIvor, C.L. Montague
1999, Estuarine, Coastal and Shelf Science (48) 701-723
Seasonal changes in freshwater inflow and other environmental conditions may induce changes in density and species composition of mangrove fishes along estuarine gradients. Fishes within mangrove habitats in a subtropical estuary were sampled monthly from May 1989 to May 1990, using block nets with rotenone and visual censuses. At 18...

Xenobiotic-induced apoptosis: significance and potential application as a general biomarker of response
Leonard I. Sweet, Dora R. Passino-Reader, Peter G. Meier, Geneva M. Omann
1999, Biomarkers (4) 237-253
The process of apoptosis, often coined programmed cell death, involves cell injury induced by a variety of stimuli including xenobiotics and is morphologically, biochemically, and physiologically distinct from necrosis. Apoptotic death is characterized by cellular changes such as cytoplasm shrinkage, chromatin condensation, and plasma membrane asymmetry. This form of cell...
Tools for groundwater protection planning: An example from McHenry County, Illinois, USA
R. C. Berg, B. Brandon Curry, R. Olshansky
1999, Environmental Management (23) 321-331
This paper presents an approach for producing aquifer sensitivity maps from three-dimensional geologic maps, called stack-unit maps. Stack-unit maps depict the succession of geologic materials to a given depth, and aquifer sensitivity maps interpret the successions according to their ability to transmit potential contaminants. Using McHenry County, Illinois, as a...
A closure test for time-specific capture-recapture data
T.R. Stanley, K.P. Burnham
1999, Environmental and Ecological Statistics (6) 197-209
The assumption of demographic closure in the analysis of capture-recapture data under closed-population models is of fundamental importance. Yet, little progress has been made in the development of omnibus tests of the closure assumption. We present a closure test for time-specific data that, in principle, tests the null hypothesis of...
