Use of egg traps to investigate lake trout spawning in the Great Lakes
Donald R. Schreiner, Charles R. Bronte, N. Robert Payne, John D. Fitzsimons, John M. Casselman
1995, Journal of Great Lakes Research (21) 433-444
Disk-shaped traps were used to examine egg deposition by lake trout (Salvelinus namaycush) at 29 sites in the Great Lakes. The main objectives were to; first, evaluate the disk trap as a device for sampling lake trout eggs in the Great Lakes, and second, summarize what has been learned about...
Evidence for lack of homing by sea lampreys
Roger A. Bergstedt, James G. Seelye
1995, Transactions of the American Fisheries Society (124) 235-239
Recently metamorphosed sea lampreys Petromyzon marinus were captured in the Devil River, a tributary to Lake Huron, during summer and autumn 1990. They were tagged with a coded wire tag and returned to the river to continue their migration to Lake Huron to begin the parasitic (juvenile) phase of their life. During...
Progress toward lake trout restoration in Lake Michigan
Mark E. Holey, Ronald W. Rybicki, Gary W. Eck, Edward H. Brown Jr., J. Ellen Marsden, Dennis S. Lavis, Michael L. Toneys, Tom N. Trudeau, Ross M. Horrall
1995, Journal of Great Lakes Research (21) 128-151
Progress toward lake trout restoration in Lake Michigan is described through 1993. Extinction of the native lake trout fishery by sea lamprey predation, augmented by exploitation and habitat destruction, resulted in an extensive stocking program of hatchery-reared lake trout that began in 1965. Sea lamprey abundance was effectively controlled using...
Pinyon-juniper woodlands
Gerald J. Gottfried, Thomas W. Swetnam, Craig D. Allen, Julio L. Betancourt, Alice L. Chung-MacCoubrey
Deborah M. Finch, Joseph A. Tainter, editor(s)
1995, General Technical Report RM-GTR-268-6
Pinyon-juniper woodlands are one of the largest ecosystems in the Southwest and in the Middle Rio Grande Basin (Fig. 1). The woodlands have been important to the region's inhabitants since prehistoric times for a variety of natural resources and amenities. The ecosystems have not been static; their distributions, stand characteristics,...

Critical thermal maxima of coho salmon (Oncorhynchus kisutch) fry under field and laboratory acclimation regimes
John T. Konecki, Carol Ann Woody, Thomas P. Quinn
1995, Canadian Journal of Zoology (73) 993-996
Juvenile coho salmon (Oncorhynchus kisutch) from three populations in Washington State were captured in the field and tested for critical thermal maximum (CTM). Tolerances varied among the populations (mean CTMs were 28.21, 29.13, and 29.23 °C) and exceeded published data from some laboratory tests. The population from a relatively cool...
Nesting success of ducks on the central Yukon Flats, Alaska
J. Barry Grand
1995, Canadian Journal of Zoology (73) 260-265
Nesting success was studied at Canvasback Lake and Mallard Lake on the Yukon Flats in interior Alaska in 1989–1991. Simple estimates of nesting success were computed using two techniques that assume a constant daily survival rate (DSR). Maximum-likelihood estimates of nesting success for all ducks, assuming constant DSR, ranged among...
Predator-prey relations and competition for food between age-0 lake trout and slimy sculpins in the Apostle Island region of Lake Superior
Patrick L. Hudson, Jacqueline F. Savino, Charles R. Bronte
1995, Journal of Great Lakes Research (21) 445-457
Slimy sculpins (Cottus cognatus) are an important component of the fish community on reefs and adjacent nursery areas of the Great Lakes and overlap spatially with age-0 lake trout (Salvelinus namaycush). Important interactions between these fishes are possible during the lake trout's first year of life, which could include predation...
Abundance indices for determining the status of lake trout restoration in Michigan waters of Lake Superior
Michael J. Hansen, Richard G. Schorfhaar, James W. Peck, James H. Selgeby, William W. Taylor
1995, North American Journal of Fisheries Management (15) 830-837
Self-sustaining populations of lake trout Salvelinus namaycush have returned to most areas in Lake Superior, but progress toward achieving historic commercial yields has been difficult to measure because of unrecorded losses to predation by sea lamprey Petromyzon marinus and to fisheries. Consequently, we developed restoration targets (catch per effort,...
Variation in brood behavior of Black Brant
James S. Sedinger, Michael W. Eichholz, Paul L. Flint
1995, The Condor (97) 107-115
We studied behavior of broods of Black Brant (Branta bernicla nigricans) during five summers between 1987 and 1993, a period in which the local breeding population increased >3-fold. Goslings spent more time foraging than adults of either sex, while adult males spent more time alert and less time foraging than...
Use of implanted satellite transmitters to locate Spectacled Eiders at-sea
Margaret R. Petersen, David C. Douglas, Daniel M. Mulcahy
1995, The Condor (97) 276-278
Population estimates of Spectacled Eiders (Somateria fischeri) on the Yukon-Kuskokwim Delta (YKD), Alaska, suggest that by 1992 the number of birds on this major nesting area had declined to 1,721 pairs, 4% of that estimated in the 1970s (Stehn st al 1993). Consequently, Spectacled Eiders were listed as threatened under...
Metabolizability and partitioning of energy and protein in green plants by yearling lesser snow geese
James S. Sedinger, Robert G. White, Jerry W. Hupp
1995, The Condor (97) 116-122
We measured apparent metabolizability of organic matter, gross energy, nitrogen and cell wall constituents of pelleted alfalfa by Lesser Snow Geese (Chen caerulescens caerulescens. We also used simultaneous measurements of energy expenditure and apparent metabolizable energy intake to estimate heat increment of feeding and net energy for production and maintenance....
