Soil-food-chain-pesticide wildlife relationships were investigated to learn the concentration of pesticide residues present in soils, macro-invertebrates, vertebrates, and seeds as a result of annual applications of aldrin at recommended rates for pest control. Two central Missouri cornfields treated witb aldrin at 1 lb/acre, for 16 and 15 of the...

Cytochrome P450 1A induction in sea ducks inhabiting nearshore areas of Prince William Sound, Alaska
Kimberly A. Trust, Daniel Esler, Bruce R. Woodin, John J. Stegeman
2000, Marine Pollution Bulletin (40) 397-403
Following the Exxon-Valdez oil spill, hepatic rates of EROD activity and thus, P450 1A expression, were significantly higher in harlequin ducks (Histrionicus histrionicus) and Barrow’s goldeneyes (Bucephala islandica) from oiled areas of Prince William Sound, Alaska when compared to birds from unoiled sites. Polychlorinated biphenyl exposure did not account for...

Preliminary study of gill NA+,K+-ATPase activity in juvenile spring chinook salmon following electroshock or handling stress
S. P. VanderKooi, William L. Gale, A.G. Maule
2000, North American Journal of Fisheries Management (20) 528-533
We compared gill Na+,K+-ATPase in subyearling and yearling spring chinook salmon Oncorhynchus tshawytscha 3 h, 24 h, and 7 d after exposure to either a short pulsed DC electroshock (300 V, 50 Hz, 8-ms pulse duration) or an acute handling stress. Mean gill Na+,K+-ATPase values ranged from 7.5 to 11.8...
Trophic ecology of largemouth bass and northern pike in allopatric and sympatric assemblages in northern boreal lakes
Craig A. Soupir, Michael L. Brown, Larry W. Kallemeyn
2000, Canadian Journal of Zoology (78) 1759-1766
Largemouth bass (Micropterus salmoides) and northern pike (Esox lucius) are top predators in the food chain in most aquatic environments that they occupy; however, limited information exists on species interactions in the northern reaches of largemouth bass distribution. We investigated the seasonal food habits of allopatric and sympatric assemblages of largemouth bass...
Age and growth of pike (Esox lucius) in Chivyrkui Bay, Lake Baikal
Randall W. Owens, Nikolai M. Pronin
2000, Journal of Great Lakes Research (26) 164-173
The purpose of this study was to describe age and growth of pike (Esox lucius) in Lake Baikal. Pike were collected with gill nets and by angling in Chivyrkui Bay in late July-early August 1993 and by gill nets in June 1995. Total length (mm), weight (g), and...
Land use, habitat, and water quality effects on macroinvertebrate communities in three watersheds of a Lake Michigan associated marsh system
P.M. Stewart, J.T. Butcher, T.O. Swinford
2000, Aquatic Ecosystem Health & Management (3) 179-189
Three watersheds within a marsh system draining into Lake Michigan in northwest Indiana, USA, were studied for differences among land use, habitat conditions and water quality to determine their influence on macroinvertebrate community structure. Much of this area had been altered for agricultural, commercial, industrial and residential land uses. Land...
Aggressive and foraging behavioral interactions among ruffe
Jacqueline F. Savino, Melissa J. Kostich
2000, Environmental Biology of Fishes (57) 337-345
The ruffe, Gymnocephalus cernuus, is a nonindigenous percid in the Great Lakes. Ruffe are aggressive benthivores and forage over soft substrates. Laboratory studies in pools (100 cm in diameter, 15 cm water depth) were conducted to determine whether fish density (low = 2, medium = 4, high...
Sustainability of the Lake Superior fish community: Interactions in a food web context

2000, Ecosystems (3) 545-560
The restoration and rehabilitation of the native fish communities is a long-term goal for the Laurentian Great Lakes. In Lake Superior, the ongoing restoration of the native lake trout populations is now regarded as one of the major success stories in fisheries management. However, populations of the deepwater morphotype (siscowet...
Nectar plant selection by the Karner blue butterfly (Lycaeides melissa samuelis) at the Indiana Dunes National Lakeshore
Ralph Grundel, Noel B. Pavlovic, Christina L. Sulzman
2000, American Midland Naturalist (144) 1-10
The Karner blue butterfly, Lycaeides melissa samuelis, is an endangered species residing in savanna and barrens habitats in the Midwest and Northeast United States. To improve our understanding of nectar plant selection patterns by the Karner blue, we examined nectar plant choices made by 146 butterflies. Within observation areas of 2-m radius...
FITPOP, a heuristic simulation model of population dynamics and genetics with special reference to fisheries
James E. McKenna Jr.
2000, Ecological Modelling (127) 81-95
Although, perceiving genetic differences and their effects on fish population dynamics is difficult, simulation models offer a means to explore and illustrate these effects. I partitioned the intrinsic rate of increase parameter of a simple logistic-competition model into three components, allowing specification of effects of relative differences in fitness and...
A new approach toward evaluation of fish bioenergetics models
Charles P. Madenjian, Daniel V. O’Connor, David A. Nortrup
2000, Canadian Journal of Fisheries and Aquatic Sciences (57) 1025-1032
A new approach was used to evaluate the Wisconsin bioenergetics model for lake trout (Salvelinus namaycush). Lake trout in laboratory tanks were fed alewife (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax), prey typical of lake trout in Lake Michigan. Food consumption and growth by lake trout during the...
Prolonged winter undernutrition and the interpretation of urinary allantoin:creatinine ratios in white-tailed deer
Glenn D. DelGiudice, Ken D. Kerr, L. David Mech, Ulysses S. Seal
2000, Canadian Journal of Zoology (78) 2147-2155
The urinary allantoin:creatinine (A:C) ratio (expressed in micromoles of allantoin to micromoles of creatinine) has shown potential as an index of recent winter energy intake in preliminary controlled studies of elk (Cervus elaphus) involving mild condition deterioration (up to 11% loss of body mass). To ensure reliable nutritional assessments of...
Postbreeding movements of American Avocets and implications for wetland connectivity in the western Great Basin
Jonathan H. Plissner, Susan M. Haig, L.W. Oring
2000, The Auk (117) 290-298
Wetlands in the western Great Basin of the United States are patchily distributed and undergo extensive seasonal and annual variation in water levels. The American Avocet (Recurvirostra americana) is one of many shorebird species that use these wetlands as breeding and migratory stopover sites and must adjust to variable conditions....
Comparisons of methods for determining dominance rank in male and female prairie voles (Microtus ochrogastor)
Richard B. Lanctot, Louis B. Best
2000, Journal of Mammalogy (81) 734-745
Dominance ranks in male and female prairie voles (Microtus ochrogaster) were determined from 6 measurements that mimicked environmental situations that might be encountered by prairie voles in communal groups, including agonistic interactions resulting from competition for food and water and encounters in burrows. Male and female groups of 6 individuals...
