Premise of research. The zosterophylls are a group of primitive land plants that possess comparatively few characters useful in taxonomic distinction but vary considerably among these characters, such that a large number of genera and species are cur

Autor: Douglas A. Jensen, Steven J. Lozano, Michael M. Petzold, Carl Richards, Donald R. Schreiner, David S. DeVault, Charles R. Bronte, Mark P. Ebener
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 60:1552-1574
Changes in Lake Superior's fish community are reviewed from 1970 to 2000. Lake trout (Salvelinus namaycush) and lake whitefish (Coregonus clupeaformis) stocks have increased substantially and may be approaching ancestral states. Lake herring (Coregon

Benthos as the basis for arctic lake food webs
Autor: Douglas A. Jensen, Michael E. McDonald, Michael E. Sierszen
Publikováno v: Aquatic Ecology. 37:437-445
Plankton have traditionally been viewed as the basis for limnetic food webs, with zooplankton acting as a gateway for energy passing between phytoplanktonic primary producers and fish. Often, benthic production has been considered to be important pri

Zebra Mussel [Dreissena polymorpha (Pallas)] Colonization of Rusty Crayfish [Orconectes rusticus (Girard)] in Green Bay, Lake Michigan
Autor: Douglas A. Jensen, John C. Brazner
Publikováno v: The American Midland Naturalist. 143:250-256
In August 1995 six rusty crayfish (Orconectes rusticus) colonized with zebra mussels (Dreissena polymorpha) were captured in small-meshed fyke-nets set as part of a fish sampling effort at Peter's Marsh and Long-Tail Point Wetland in lower Green Bay.

Relative Abundance and Distribution of Ruffe (Gymnocephalus cernuus) in a Lake Superior Coastal Wetland Fish Assemblage
Autor: John C. Brazner, Armond Lemke, Danny K. Tanner, Douglas A. Jensen
Publikováno v: Journal of Great Lakes Research. 24:293-303
Fish assemblages from Allouez Bay Wetland in the St. Louis River estuary were sampled with fyke-nets from May to October, 1995, to characterize typical use patterns in different seasons and microhabitats. The relative abundance and distribution of ru

Bioassay Directed Characterization of the Acute Aquatic Toxicity of a Creosote Leachate
Autor: Lawrence P. Burkhard, Douglas W. Kuehl, Gerald T. Ankley, Douglas A. Jensen
Publikováno v: Hazardous Waste and Hazardous Materials. 7:283-291
A toxicity based approach to chemical characterization has been used to identify select toxicants in an aqueous leachate of creosote. Gas Chromatographic-mass spectral analysis of toxic fractions of the leachate identified pentachlorophenol and a mix

Characteristics of surfactants in toxicity identification evaluations
Autor: Gregory S. Peterson, Marta T. Lukasewycz, Gerald T. Ankley, Douglas A. Jensen
Publikováno v: Chemosphere. 21:3-12
The behavior of a number of anionic, nonionic and cationic surfactants in manipulations associated with toxicity identification evaluations was studied. It was found that toxicity of the surfactants could be removed from aqueous samples via aeration,
