Impact of zebra and quagga mussels (Dreissena spp.) on freshwater unionids (Bivalvia: Unionidae) in the Detroit River of the Great Lakes
D. W. Schloesser, W. P. Kovalak, G. D. Longton, K. L. Ohnesorg, R. D. Smithee
1998, American Midland Naturalist (140) 299-313
To assess the impact of zebra and quagga mussel (Dreissena spp.) infestation on unionids, unionids (Bivalvia: Unionidae) were sampled in the Detroit River in 1982–1983, before mussels invaded the river, and in 1992 and 1994, after mussels invaded the river. Live unionids at four stations along the southeastern shore accounted for...
Electrogeochemical sampling with NEOCHIM - results of tests over buried gold deposits
R. W. Leinz, D. B. Hoover, D. L. Fey, D. B. Smith, T. Patterson
1998, Journal of Geochemical Exploration (61) 57-86
Electrogeochemical extraction methods are based on the migration of ions in an electric field. Ions present in soil moisture are transported by an applied current into fluids contained in special electrodes placed on the soil. The fluids are then collected and analyzed. Extractions are governed by Faraday's and Ohm's laws...

Virulence of Renibacterium salmoninarum to salmonids
C.E. Starliper, D. R. Smith, T. Shatzer
1997, Journal of Aquatic Animal Health (9) 1-7
Virulence of Renibacterium salmoninarum isolates representing five origins was evaluated in eight salmonid hosts; four origins were of Lake Michigan and the fifth was of the Pacific Northwest. The species type strain, ATCC (American Type Culture Collection) 33209, was also included. Each isolate was grown in a kidney disease medium...
Is incest common in gray wolf packs?
Deborah E. Smith, Thomas J. Meier, Eli Geffen, L. David Mech, John W. Burch, Layne G. Adams, Robert K. Wayne
1997, Behavioral Ecology (8) 384-391
Wolf packs generally consist of a breeding pair and their maturing offspring that help provision and protect pack young. Because the reproductive tenure in wolves is often short, reproductively mature offspring might replace their parents, resulting in sibling or parent-offspring matings. To determine the extent of incestuous pairings, we measured...
U.S. Geological Survey studies of water co-produced with oil and gas: Implications for future petroleum resource development
George N. Breit, Yousif K. Kharaka, Robert A. Zielinski, C. A. Rice, Bruce D. Smith, Jennie L. Ridgley
1997, Conference Paper, SPE/EPA exploration and production environmental conference
The U.S. Geological Survey is conducting research on the impacts of produced waters on petroleum resource development and the environment. Ongoing multidisciplinary investigations are focused on the 1) quantity and quality of current water production, 2) geologic and geochemical parameters that influence the viability of injection wells, and 3) processes...
Hydrogeology and simulation of ground-water flow in the thick regolith-fractured crystalline rock aquifer system of Indian Creek basin, North Carolina
Charles C. Daniel, Douglas G. Smith, Jo Leslie Eimers
1997, Water Supply Paper 2341-C
The Indian Creek Basin in the southwestern Piedmont of North Carolina is one of five type areas studied as part of the Appalachian Valleys-Piedmont Regional Aquifer-System analysis. Detailed studies of selected type areas were used to quantify ground-water flow characteristics in various conceptual hydrogeologic terranes. The conceptual hydrogeologic terranes are...

A revised annotated checklist of the Chironomidae (Insecta: Diptera) of the southeastern United States
Broughton A. Caldwell, Patrick L. Hudson, David R. Lenat, David Smith
1997, Transactions of the American Entomological Society (123) 1-53
A revised annotated checklist for the chironomid midges (Diptera: Chironomidae) of the southeastern United States is presented that includes the states of Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee. Much of the information concerns occurrence and habitat preference records based upon the authors' data, as well as published...
Zebra mussel induced mortality of unionids in firm substrata of western Lake Erie and a habitat for survival
D. W. Schloesser, R. D. Smithee, G. D. Longton, W. P. Kovalak
1997, American Malacological Bulletin (14) 67-74
The present study was conducted to determine impacts of zebra mussel [Dreissena polymorpha (Pallas, 1771); Dreissenidae] infestation on unionids in firm substrata in western Lake Erie. Unionid mollusks were collected at a total of 15 stations on three offshore depth contours (2, 3, and 4 m) in 1983 (before...

Continuous monitoring of dissolved oxygen and total dissolved gas pressure based on head-space partial pressures
B.J. Watten, D. R. Smith, W. J. Ridge
1997, Journal of the World Aquaculture Society (28) 316-333
We describe an instrument prototype that measures total dissolved gas pressure (TGP) and dissolved oxygen (DO) without need for standard wetted probe membranes or gas permeable tubing. Measurements were based instead on gas-phase partial pressures that develop within the head-space of a pressure vessel, and on Henry's Law. Performance trials...
Evidence of secondary consumption of invertebrate prey by Double-crested Cormorants
J. H. Johnson, R. M. Ross, D. R. Smith
1997, Waterbirds (20) 547-551
The piscivorous nature of the Double-crested Cormorant (Phalacrocorax auritus) is well documented. However, many researchers who have used regurgitated pellets to describe the diet of cormorants report that invertebrates compose a small but consistent portion of the diet. We examined the hypothesis that invertebrates found in pellets are primarily the...
Differences in detection of Aeromonas salmonicida in covertly infected salmonid fishes by the stress-inducible furunculosis test and culture-based assays
Rocco C. Cipriano, Larisa Ford, David R. Smith, J. H. Schachte, C. J. Petrie
1997, Journal of Aquatic Animal Health (9) 108-113
Accurate detection of Aeromonas salmonicida subsp. salmonicida (the cause of furunculosis disease) in covertly infected salmonids is difficult and is a cause of concern for those involved in fish health inspection and resource management programs. In this study, we examined populations of brook trout Salvelinus fontinalis, Atlantic salmon Salmo salar, and lake trout Salvelinus namaycush that previously sustained...

Denning behaviour of non-gravid wolves, Canis lupus
L. D. Mech, M.K. Phillips, D.W. Smith, T.J. Kreeger
1996, Canadian Field-Naturalist (110) 343-345
Wild wolves (Canis lupus) that had produced pups in earlier years but were not currently pregnant, and ovariectomized captive wolves, dug dens during and after the whelping season even though they produced no pups. These observations suggest that den digging is not a function of pregnancy or of ovarian...
Diurnal raptors in the fragmented rain forest of the Sierra Imataca, Venezuela

The rain forest of the Sierra Imataca in eastern Venezuela has been subjected to extensive deforestation for pastures and agricultural settlements. In the last decade the opening of access roads combined with intensified logging and mining activities have fragmented a significant portion of the remaining forest. We noted...

Factors affecting visibility rate of aerial waterfowl surveys in the Mississippi alluvial valley
D. R. Smith, K. J. Reinecke, M.J. Conroy, M.W. Brown, J.R. Nassar
1995, Journal of Wildlife Management (59) 515-527
Because visibility bias can confound attempts to detect changes in abundance, we evaluated factors that affect visibility rate in aerial surveys of wintering waterfowl. We placed waterfowl decoys in 32 2- x 0.25-kin strip transects in the Mississippi Alluvial Valley (MAV) during February 1990 and 1991 and observed the...
