Intraspecific mitochondrial DNA variation in North American cervids
M. A. Cronin
1992, Journal of Mammalogy (73) 70-82
Intraspecific variation in mitochondrial DNA of North American cervids was assessed with restriction enzymes to determine relationships among populations and subspecies. No variation was detected in moose (Alces alces) and little in elk (Cervus elaphus). Caribou (Rangifer tarandus), white-tailed deer (Odocoileus virginianus), and mule deer (Odocoileus hemionus) possessed considerable...

Density-dependent recruitment of the bloater (Coregonus hoyi) in Lake Michigan
Edward H. Brown Jr., Gary W. Eck
1992, Polskie Archiwum Hydrobiologii (39) 289-297
Density-dependent recruitment of the bloater (Coregonus hoyi) in Lake Michigan during and after recovery of the population in about 1977-1983 was best reflected in the fit of the Beverton-Holt recruitment function to age -1 and -2 recruits and estimated eggs of parents surveyed with trawls. A lower growth rate...
Diurnal flight time of wintering Canada geese: consideration of refuges and flight energetics
J. E. Austin, D.D. Humburg
1992, Prairie Naturalist (24) 21-30
We monitored individual radio-equipped Canada geese (Branta canadensis) associated with a federal refuge to assess flight activities from late fall through spring. The number of flights per day was lowest in late fall when most geese remained within the refuge and highest in spring when they moved increasingly beyond the...
Lake trout spawning habitat in the Six Fathom Bank-Yankee Reef lake trout sanctuary, Lake Huron
Thomas A. Edsall, Charles L. Brown, Gregory W. Kennedy, Thomas P. Poe
1992, Journal of Great Lakes Research (18) 70-90
Attempts to reestablish self-sustaining stocks of lake trout (Salvelinus namaycush) in the lower four Great Lakes, where the species was extinguished in the 1950s and 1960s, have been largely unsuccessful. To avoid many of the problems believed to be contributing to this failure, the fishery management community recently established several...
A new device for collection of interstitial water from wetland sediments
Ned H. Euliss Jr., Ronald K. Barnes
1992, Wetlands Ecology and Management (1) 233-237
A sampler for collection of interstitial water from wetland sediments is described. It differs from other sampling devices because it does not have to be filled with solution to facilitate diffusion, it does not have to be removed from the wetland to collect samples, and it can be used to...

Environmental influences on major waterfowl diseases
M. Friend
1992, Conference Paper, Transactions of the 57th North American Wildlife and Natural Resources Conference
The decline of North American waterfowl resources since the 1960s is well-known to this audience and need not be detailed to establish that population numbers for several key waterfowl species are at or near their lowest levels since records have been kept. Loss of habitat is an accepted major cause...
Chemical regulation of spawning in the zebra mussel (Dreissena polymorpha)
Jeffrey L. Ram, S. Jerrine Nichols
Thomas F. Nalepa, Donald W. Schloesser, editor(s)
1992, Book chapter, Zebra mussels: Biology, impacts, and control
Previous literature suggests that spawning in bivalves is chemically regulated, both by environmental chemical cues and by internal chemical mediators. In a model proposed for zebra mussels, chemicals from phytoplankton initially trigger spawning, and chemicals associated with gametes provide further stimulus for spawning. The response to environmental chemicals...

Implications for faunal habitat related to altered macrophyte structure in regulated lakes in northern Minnesota
Douglas A. Wilcox, James E. Meeker
1992, Wetlands (12) 192-203
Water-level regulation has altered the plant species composition and thus the structure of nearshore aquatic macrophyte communities in two regulated lakes in northern Minnesota as compared with a nearby unregulated lake. Results of previous faunal studies in the regulated lakes were used as a basis for assessing the effects of...

Predation of the zebra mussel (Dreissena polymorpha) by freshwater drum in western Lake Erie
John R. P. French III, Michael T. Bur
Thomas F. Nalepa, Donald W. Schloesser, editor(s)
1992, Book chapter, Zebra mussels: Biology, impacts, and control
Environmental and economic problems associated with the colonization of zebra mussels (Dreissena polymorpha) in western Lake Erie created a need to investigate control mechanisms. Predation by fishes is one potential means of control, but predation on zebra mussels by native fishes in Lake Erie is unknown. The freshwater...

The U.S. Geological Survey library classification system has been designed for an earth science library. It is a tool for assigning classification numbers to earth science and allied pure science library materials in order to collect these materials into related subject groups on the library shelves and arrange them alphabetically...
