Historical Winter Diets Of Mink (Mustela Vison) In Nebraska, Justin D. Hoffman, Sam Wilson, Hugh H. Genoways Jan 2009

Historical Winter Diets Of Mink (Mustela Vison) In Nebraska, Justin D. Hoffman, Sam Wilson, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Currently there are no published accounts of the specific diets of mink (Mustela vison) in Nebraska. Herein, we present findings of an historic data set on the winter diets of mink in Nebraska. Gastrointestinal (GI) tracts of mink were collected by the Nebraska Game and Parks Commission during the 1946-1947 fur trapping season. The contents of the GI tracts were identified as specifically as possible and percentage of occurrence and percentage of total volume was calculated for each prey item. Mammals and bony fish were the most encountered items. Among mammals, rabbits and muskrats (Ondatra zibethicus) …

Characterization Of 24 Microsatellite Loci In Delta Smelt, Hypomesus Transpacificus, And Their Cross-Species Amplification In Two Other Smelt Species Of The Osmeridae Family, Kathleen M. Fisch, Jessica Lynn Petersen, Melinda R. Baerwald, John K. Pedroia, Bernie May

Department of Animal Science: Faculty Publications

We characterized 24 polymorphic tetranucleotide microsatellite loci for delta smelt (Hypomesus transpacificus) endemic to the San Francisco Bay Estuary, California, USA. Screening of samples (n = 30) yielded two to 26 alleles per locus with observed levels of heterozygosity ranging from 0.17 to 1.0. Only one locus deviated from Hardy–Weinberg equilibrium, suggesting these individuals originate from a single panmictic population. Linkage disequilibrium was found in two pairs of loci after excluding the locus out of Hardy–Weinberg equilibrium. Twenty-two primer pairs cross-amplified in wakasagi smelt (Hypomesus nipponensis), and 15 primer pairs cross-amplified in longfin smelt ( …


Estimating Predation On Declining River Herring: Tag-Recapture Study Of Striped Bass In The Connecticut River, Eric T. Schultz, Justin P. Davis, Jason Vokoun Jan 2009

Estimating Predation On Declining River Herring: Tag-Recapture Study Of Striped Bass In The Connecticut River, Eric T. Schultz, Justin P. Davis, Jason Vokoun

EEB Articles

Populations of anadromous alewife Alosa pseudoharengus and blueback herring Alosa aestivalis, collectively referred to as river herring, have declined in the Connecticut River. A hypothesis for why river herring have declined is that predation pressures have increased associated with recent increases in abundance of striped bass Morone saxatilis. Information on striped bass abundance, size structure, and consumption rates are required to test this hypothesis. This study was designed to provide estimates of striped bass population size in the Connecticut River during the spring migration season, via an intensive mark-recapture exercise and either an open or robust mark-recapture model. …


Seal Bounties In Maine And Massachusetts, 1888 To 1962, Barbarai Lelli, David Harris Ph.D, Aboueissa Abouel-Makarim Jan 2009

Seal Bounties In Maine And Massachusetts, 1888 To 1962, Barbarai Lelli, David Harris Ph.D, Aboueissa Abouel-Makarim

Faculty Publications

Maine and Massachusetts paid bounties on seals during the 19th and 20th centuries. To determine the number of seals killed for bounty, we examined historical records of bounty claims, and used geographic information systems and multiple linear regression to find predictors of places where large numbers of bounties were paid. We found records of 24,831 bounties paid in Maine (1891-1945) and 15,690 in Massachusetts (1888-1962), Considering possible fraud, missing data, and seals struck and lost, this suggests that 72,284 to 135,498 seals were killed in the bounty hunt, probably enough to account for regional declines in seal populations. Larger numbers …


Thirty-Seven Additional Microsatellite Loci In The Pacific Lion-Paw Scallop (Nodipecten Subnodosus) And Cross-Amplification In Other Pectinids, Jessica Lynn Petersen, Ana M. Ibarra, Bernie May Jan 2009

Thirty-Seven Additional Microsatellite Loci In The Pacific Lion-Paw Scallop (Nodipecten Subnodosus) And Cross-Amplification In Other Pectinids, Jessica Lynn Petersen, Ana M. Ibarra, Bernie May

Department of Animal Science: Faculty Publications

We characterized 37 new microsatellite markers in the Pacific lion-paw scallop (Nodipecten subnodosus) and tested for cross-amplification in four other species. Genetic diversity was estimated using 24 individuals from the Lagoon Ojo de Liebre, B.C.S., Mexico. Allelic richness varied from 5 to 27 alleles per locus and the average expected heterozygosity was 0.76. Ten loci exhibited significant departure from Hardy–Weinberg equilibrium likely due to the presence of null alleles. Sixteen of these markers cross-amplified in closely related N. nodosus, while little or no amplification was observed in three Argopecten species.


Condition Relative To Phenotype For Bass Populations In Southern Arkansas Lakes, R. Allen, C. Cato, Colton Dennis, Ronald L. Johnson Jan 2009

Condition Relative To Phenotype For Bass Populations In Southern Arkansas Lakes, R. Allen, C. Cato, Colton Dennis, Ronald L. Johnson

Journal of the Arkansas Academy of Science

Southern Arkansas reservoir largemouth bass populations (Micropterus salmoides) are often supplemented with stocks of Florida bass (M. floridanus) in an attempt to boost the frequency of hybrid and trophy bass. Stocking rates of Florida bass among these lakes are highly variable. We determined bass phenotype composition among 12 lake populations based upon stocking protocols: exclusively Florida bass, primarily Florida bass, mixed stocking protocol and primarily largemouth bass. We also compared condition among phenotypes (n =2,100) to test for hybrid or phenotype vigor. Mean relative weight of bass for most lakes but SWEPCO Lake (mean Wr = 72) were ≥ 90. …


Temporal Changes Of Largemouth Bass Alleles In A Northern Arkansas Reservoir Stocked With Florida Bass, R. Allen, Ronald L. Johnson Jan 2009

Temporal Changes Of Largemouth Bass Alleles In A Northern Arkansas Reservoir Stocked With Florida Bass, R. Allen, Ronald L. Johnson

Journal of the Arkansas Academy of Science

Southwest Electric Power Company (SWEPCO) Lake in northwest Arkansas is a thermal cooling pond for the Flint Creek Power Station. This reservoir has been regularly stocked with Florida bass (Micropterus floridanus) on top of a pre-existent largemouth bass (M. salmoides) population since its creation in 1976. Allozyme analysis of diagnostic loci in 1995-1996 revealed that 62% of the alleles were Florida bass alleles and that most fish were FX hybrids (77%). Microsatellite analysis of diagnostic loci in 2006 revealed that 78% of the alleles were Florida bass alleles and that most fish were FX-Florida hybrid bass (59%), with the remainder …

Determination Of Benthic Soil Conditions Using Nematodes: Nematode Foodweb Conditions Of Fish Ponds In The Lincoln And Desha Counties Of Arkansas, M. M. Matute, P. W. Perschbacher, A. Newell

Journal of the Arkansas Academy of Science

We determined the health status of similar channel catfish (Ictalurus punctatus) ponds in Lincoln and Desha counties of Arkansas, using the nematode soil food web condition as our reference point. Soil nematodes were categorized into colonizer-persister (cp) groups, based on their life course characteristics e.g sensitivity to environmental changes, body size, etc. These cp groups represent different components of the soil food web, which in turn were indicators of soil conditions. Benthic soil samples were collected at four week intervals over a 4-month period, from 6-ponds in each county. The nematodes were extracted according to standard methods and the recovered …
