Biodepuration Of Polynuclear Aromatic Hydrocarbons From A Bivalve Mollusk, Mercenaria Mercenaria L, John T. Tanacredi Ph.D., Raul R. Cardenas
Biodepuration Of Polynuclear Aromatic Hydrocarbons From A Bivalve Mollusk, Mercenaria Mercenaria L, John T. Tanacredi Ph.D., Raul R. Cardenas
Faculty Works: CERCOM
Mercenaria mercenaria, exposed in vitro for 48 h to nine parent polynuclear aromatic hydrocarbons (PAHs) found in waste crankcase oil (WCCO) and analysed by multiparametric analysis over a 45- day depuration period in an activated carbon filtration aquaria system, did not depurate PAHs, but rather maintained them at detectable levels. Uptake of PAHs was shown to be directly related to clam weight. A cluster analysis of empirical results reaffirmed a biostabilization in PAH groupings in clam tissue over a 45-day depuration period and exhibited no evidence of a decreasing trend in total PAHs when subjected to ANOVA. Due to the …

Endangered And Threatened Wildlife And Plants; Determination Of Endangered Status For The Winged Mapleleaf Freshwater Mussel
Endangered Species Bulletin
The Fish and Wildlife Service (Service) determines the winged mapleleaf mussel (Quodrulo frogoso) to be an endangered species under the authority of the Endangered Species Act of 1973, as amended (16 U.S.C 1531 et seq.) (Act). Historically, this freshwater mussel occurred extensively in the Mississippi, Tennessee, Ohio, and Cumberland River drainages in the states of Ohio, Indiana, Missouri, Tennessee, Nebraska, Iowa, Illinois, Wisconsin, Oklahoma and Kentucky. As a result of land use changes, river alterations and pollution, the winged mapleleaf mussel has been reduced to a single known population located in the St. Croix River between northwestern Wisconsin …

The Distribution And Reproductive Phenology Of The Milkweeds (Asclepiadaceae: Asclepias And Cynanchum) In Nebraska, Robert B. Kaul, Steven B. Rolfsmeier, Jeffrey J. Esch
The Distribution And Reproductive Phenology Of The Milkweeds (Asclepiadaceae: Asclepias And Cynanchum) In Nebraska, Robert B. Kaul, Steven B. Rolfsmeier, Jeffrey J. Esch
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The Asclepiadaceae are represented in Nebraska by seventeen native species of Asclepias and one of Cynanchum. Two species are here added to the State's flora: Asclepias asperula and A. purpurascens. Detailed county distribution maps are presented for all species based upon our extensive field and herbarium work, and numerous additions and corrections are made to the maps published in the Atlas of the Flora of the Great Plains in 1977. A map is presented showing the zone of hybridization of A. speciosa with A. syriaca in central Nebraska. Data are given on flowering and fruiting phenology for each …

Pasture Condition Guides For The Murchison River Catchment, A Fox, T R. Eckersley
Pasture Condition Guides For The Murchison River Catchment, A Fox, T R. Eckersley
Soil conservation survey collection
Knowledge of the pasture resource and its capabilities is essential to sustainable use of the rangelands. Rangeland managers must be able to recognise firstly the different pasture types, and secondly, the differences between present condition classes for each type. Both factors affect the stock carrying capacity, and appropriate pastoral management of a pasture. This guide has been produced for use by pastoralists to assist them to recognise and assess the condition of the perennial pasture resource of their own properties. The guide describes the condition states found in 10 of the most widespread pastures of the Murchison River catchment (Fig. …
New And Corrected Floristic Records For Nebraska, Steven B. Rolfsmeier, Robert B. Kaul, David M. Sutherland
New And Corrected Floristic Records For Nebraska, Steven B. Rolfsmeier, Robert B. Kaul, David M. Sutherland
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Nineteen species (including eight Eurasian ones) are newly recorded for Nebraska: Alopecurus arundinaceus, Amaranthus californicus, Asclepias asperula, A. purpurascens, Cardamine {lexuosa*, Centaurea diffusa, Dipsacus laciniatus, Eriochloa villosa, Euclidium syriacum, Gentiana alba, Geranium viscosissimum, Geum vernum, Goodyera oblongifolia, Haplopappus multicaulis, Heterotheca latifolia, Lathyrus tuberosus, Polygonum douglasii, Scirpus saximontanus, Veronica biloba. Twenty-one others are shown to be more widespread in Nebraska than previously known, one has a more restricted range than previously reported, two (Scirpus smithii, S. torreyi) are deleted from the flora based upon corrected identifications, and the status of some rarely-collected species is updated. Thirty-two additions, two …
Black-Capped Vireo Recovery Plan, Joseph A. Grzybowski
Black-Capped Vireo Recovery Plan, Joseph A. Grzybowski
Endangered Species Bulletin
Current Species Status: This species is listed as endangered. The number of individuals is unknown. However, it has undergone substantial range reduction in Kansas, Oklahoma, and Texas. It is extirpated in Kansas, and the Oklahoma population is below 300 birds. Declines have also been documented over much of the species’ range in Texas. Its status is uncertain in Coahuila, Mexico.
Habitat Requirements and Limiting Factors: The black-capped vireo occurs in mixed deciduous/evergreen shrubland. Breeding vireos use shrubby growth of irregular height and distribution with spaces between the small thickets and clumps and with vegetative cover extending to ground …
Introgression Of Coyote Mitochondrial Dna Into Sympatric North American Gray Wolf Populations, Niles Lehman, Andrew Eisenhawer, Kimberly Hansen, L. David Mech, Rolf O. Peterson, Peter J. P. Gogan, Robert K. Wayne
Introgression Of Coyote Mitochondrial Dna Into Sympatric North American Gray Wolf Populations, Niles Lehman, Andrew Eisenhawer, Kimberly Hansen, L. David Mech, Rolf O. Peterson, Peter J. P. Gogan, Robert K. Wayne
USGS Northern Prairie Wildlife Research Center
Mitochondrial DNA (mtDNA) genotypes of gray wolves and coyotes from localities throughout North America were determined using restriction fragment length polymorphisms. Of the 13 genotypes found among the wolves, 7 are clearly of coyote origin, indicating that genetic transfer of coyote mtDNA into wolf populations has occurred through hybridization. The transfer of mtDNA appears unidirectional from coyotes into wolves because no coyotes sampled have a wolf-derived mtDNA genotype. Wolves possessing coyote-derived genotypes are confined to a contiguous geographic region in Minnesota, Ontario, and Quebec, and the frequency of coyote- type mtDNA in these wolf populations is high (> 500%). The …

Lists Of Larval Worms From Marine Invertebrates Of The Pacific Coast Of North America, Hilda Lei Ching
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Immature stages of seventy-three digenetic trematodes are listed by their families, marine invertebrate hosts, and localities and then cross listed according to their molluscan hosts. The list contains many new host records, and larval stages of fifteen digenetic trematodes were newly recorded from gastropods from British Columbia and California. A list of immature stages of fourteen cestodes, acanthocephaIans, and nematodes is also included.
