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...
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...
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...

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...

Year-round movements of a Wahlberg's Eagle Aquila wahlbergi tracked by satellite

An adult female Wahlberg's Eagle from northern Namibia was tracked by satellite ovcr a total distance of 8816 km and located 104 times between 11 February and 4 November 1994. It migrated on an almost due north heading to northern Cameroon, north-eastern Nigeria and western Chad through the rain forest...
Point count length and detection of forest neotropical migrant birds

1995, Report, Monitoring Bird Populations by Point Counts
Comparisons of bird abundances among years or among habitats assume that the rates at which birds are detected and counted are constant within species. We use point count data collected in forests of the Mid-Atlantic states to estimate detection probabilities for Neotropical migrant bird species as a function of count...
Water-quality conditions at selected landfills in Mecklenburg County, North Carolina, 1986-92
G.M. Ferrell, D.G. Smith
1995, Water-Resources Investigations Report 95-4067
Water-quality conditions at five municipal landfills in Mecklenburg County, North Carolina, were studied during 1986-92. Analytical results of water samples from monitoring wells and streams at and near the landfills were used to evaluate effects of leachate on surface and ground water. Ground-water levels at monitoring wells were used to...
Factors affecting visibility rate of aerial waterfowl surveys in the Mississippi alluvial valley

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-km strip transects in the Mississippi Alluvial Valley (MAV) during February 1990 and 1991 and observed the decoys...
