Reproductive biology and juvenile recruitment of the shinyrayed pocketbook, Lampsilis subangulata (Bivalvia: Unionidae) in the Gulf Coastal Plain
C. A. O’Brien, Jayne Brim-Box
1999, American Midland Naturalist (142) 129-140
The reproductive biology, glochidial morphology and recruitment of the federally endangered shinyrayed pocketbook, Lampsilis subangulata, were studied from May 1995 to July 1996 in the Flint River system, Georgia. Gravid female L. subangulata were found nine months of the year. On 19 May 1995, a L. subangulata was discovered releasing a superconglutinate,...
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...

Bioassessment of mercury, cadmium, polychlorinated biphenyls, and pesticides in the upper Mississippi river with Zebra mussels (Dreissena polymorpha)
W. Gregory Cope, Michelle R. Bartsch, Ronald G. Rada, Steven J. Balogh, John E. Rupprecht, R. David Young, D. Kent Johnson
1999, Environmental Science & Technology (33) 4385-4390
Zebra mussels (Dreissena polymorpha) were sampled from artificial substrates deployed from May 30 to October 19, 1995, at 19 locks and dams from Minneapolis, MN, to Muscatine, IA. Analyses of composite tissue samples of zebra mussels (10−20-mm length) revealed accumulation of mercury (Hg), cadmium (Cd), and polychlorinated biphenyls (PCBs) during...
Implications of climate change for Alaska's seabirds
Rosa Meehan, G. Vernon Byrd, George J. Divoky, John F. Piatt
Gunter Weller, Patricia A. Anderson, editor(s)
1999, Conference Paper, Assessing the consequences of climate change for Alaska and the Bering Sea region
Seabirds are prominent and highly visible components of marine ecosystems that will be affected by global climate change. The Bering Sea region is particularly important to seabirds; populations there are larger and more diverse than in any similar region in North America—over 90% of seabirds breeding in the continental United...
Enhancement of anti-Aeromonas salmonicida activity in Atlantic salmon (Salmo salar) macrophages by a mannose-binding lectin
C. A. Ottinger, S.C. Johnson, K.V. Ewart, L.L. Brown, N.W. Ross
1999, Comparative Biochemistry and Physiology, Part C: Pharmacology, Toxicology and Endocrinology (123) 53-59
We investigated the effects of a calcium-dependent mannose-binding lectin isolated from the serum of Atlantic salmon on Aeromonassalmonicida viability and the anti-A. salmonicida activity of Atlantic salmon macrophages. In the absence of other factors, binding of this lectin at concentrations of 0.8, 4.0 and 20.0 ng ml−1 to virulent A....
Protocol and practice in the adaptive management of waterfowl harvests
F. Johnson, K. Williams
1999, Conservation Ecology (3)
Waterfowl harvest management in North America, for all its success, historically has had several shortcomings, including a lack of well-defined objectives, a failure to account for uncertain management outcomes, and inefficient use of harvest regulations to understand the effects of management. To address these and other concerns, the U.S. Fish...
The insect trace fossil Tonganoxichnus from the middle Pennsylvanian of Indiana: Paleobiologic and paleoenvironmental implications
M. Gabriela Mángano, Conrad C. Labandeira, Erik P. Kvale, Luis A. Buatois
1999, Ichnos: An International Journal for Plant and Animal Traces (8) 165-175
The ichnogenus Tonganoxichnus, produced by one or more monuran insect taxa, is now recorded from the Middle Pennsylvanian Mansfield Formation of Indiana. Tonganoxichnus is a resting trace that has three important implications. First, it represents a recurrent behavioral pattern in Upper Carboniferous to Lower Permian marginal marine environments of North America. Second, it...
Detailed evaluation of gas hydrate reservoir properties using JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well downhole well-log displays
T. S. Collett
1999, Bulletin of the Geological Survey of Canada 295-311
The JAPEX/JNOC/GSC Mallik 2L-38 gas hydrate research well project was designed to investigate the occurrence of in situ natural gas hydrate in the Mallik area of the Mackenzie Delta of Canada. Because gas hydrate is unstable at surface pressure and temperature conditions, a major emphasis was placed on the downhole...
Evolution of composition of major mineral phases in layered complex of ophiolite assemblage: Evidence for the Voykar ophiolites (Polar urals, Russia)
E.V. Sharkov, A.V. Chistyakov, E. E. Laz’ko, J. E. Quick
1999, Conference Paper, Ofioliti
We present a detailed study of compositional variation of major minerals through a cross section of the layered complex of the Late Devonian Voykar ophiolite assemblage (Polar Urals). The principal characteristics of this layered complex suggest crystallization from a periodically replenished open magma system in a tectonically dynamic, oceanic environment....
Kinematic analysis of melange fabrics: Examples and applications from the McHugh Complex, Kenai Peninsula, Alaska
T.M. Kusky, D. C. Bradley
1999, Journal of Structural Geology (21) 1773-1796
Permian to Cretaceous melange of the McHugh Complex on the Kenai Peninsula, south-central Alaska includes blocks and belts of graywacke, argillite, limestone, chert, basalt, gabbro, and ultramafic rocks, intruded by a variety of igneous rocks. An oceanic plate stratigraphy is repeated hundreds of times across the map area, but most...
Characterization of fly ash from low-sulfur and high-sulfur coal sources: Partitioning of carbon and trace elements with particle size
James C. Hower, A.S. Trimble, Cortland F. Eble, Curtis A. Palmer, Allan Kolker
1999, Energy Sources (21) 511-525
Fly ash samples were collected in November and December of 1994, from generating units at a Kentucky power station using high- and low-sulfur feed coals. The samples are part of a two-year study of the coal and coal combustion byproducts from the power station. The ashes were wet screened at...
Coral adaptation and acclimatization: A most ingenious paradox
R. W. Buddemeier, S. V. Smith
1999, American Zoologist (39) 1-9
Reef corals and the communities they form evidently possess effective mechanisms of adaptation and acclimation that have ensured their survival and recurrence over geologic time. Current reef degradation suggests that these mechanisms are being taxed beyond their limits; understanding of the problem is hampered by serious inadequacies in our understanding...
The potential for free and mixed convection in sedimentary basins
Jeff P. Raffensperger, D. Vlassopoulos
1999, Hydrogeology Journal (7) 505-520
Free thermal convection and mixed convection are considered as potential mechanisms for mass and heat transport in sedimentary basins. Mixed convection occurs when horizontal flows (forced convection) are superimposed on thermally driven flows. In cross section, mixed convection is characterized by convection cells that migrate laterally...
Nearshore versus offshore copper loading in Lake Superior sediments: Implications for transport and cycling
J.J. Kolak, D.T. Long, W.C. Kerfoot, T.M. Beals, Steven J. Eisenreich
1999, Journal of Great Lakes Research (25) 611-624
A thorough understanding of the fate and transport of metals in Lake Superior is necessary in order to predict the ability of Lake Superior to recover from anthropogenic perturbations (copper mining). Sediment cores were collected from nearshore and offshore sites in...

P. J. Squillace, M.J. Moran, W.W. Lapham, C. V. Price, R.M. Clawges, J.S. Zogorski
1999, Environmental Science & Technology (33) 4176-4187
As part of the National Water-Quality Assessment Program of the U.S. Geological Survey, an assessment of 60 volatile organic compounds (VOCs) in untreated, ambient groundwater of the conterminous United States was conducted based on samples collected from 2948 wells between 1985 and 1995. The samples represent urban and rural areas...
Use of generalized linear models and digital data in a forest inventory of northern Utah
Gretchen G. Moisen, Thomas C. Edwards Jr.
1999, Journal of Agricultural, Biological, and Environmental Statistics (4) 372-390
Forest inventories, like those conducted by the Forest Service's Forest Inventory and Analysis Program (FIA) in the Rocky Mountain Region, are under increased pressure to produce better information at reduced costs. Here we describe our efforts in Utah to merge satellite-based information with forest inventory data for the purposes of...
