Evaluation of the vaccine's safety in non-target species was considered necessary prior to field use. Between June 1998 and December 1999, ground squirrels (</span><i>Spermophilus richardsonii</i><span>,&nbsp;</span><i>n</i><span>&nbsp;= 21), deer mice (</span><i>Peromyscus maniculatus</i><span>,&nbsp;</span><i>n</i><span>&nbsp;= 14), prairie voles (</span><i>Microtus ochrogaster</i><span>,&nbsp;</span><i>n</i><span>&nbsp;= 21), and ravens (</span><i>Corvus corax</i><span>,&nbsp;</span><i>n</i><span>&nbsp;= 13) were orally inoculated with SRB51 or physiologic saline. Oral and rectal swabs and blood samples were collected for bacteriologic evaluation. Rodents were necropsied at 8 to 10 wk and 12 to 21 wk post inoculation (PI), and ravens at 7 and 11 wk PI. Spleen, liver and reproductive tissues were collected for bacteriologic and histopathologic evaluation. No differences in clinical signs, appetite, weight loss or gain, or activity were observed between saline- and SRB51-inoculated animals in all four species. Oral and rectal swabs from all species were negative throughout the study. In tissues obtained from SRB51-inoculated animals, the organism was isolated from six of seven (86%) ground squirrels, one of six (17%) deer mice, none of seven voles, and one of five (20%) ravens necropsied at 8, 8, 10, and 7 wk PI, respectively. Tissues from four of seven (57%) SRB51-inoculated ground squirrels were culture positive for the organism 12 wk PI; SRB51 was not recovered from deer mice, voles, or ravens necropsied 12, 21, or 11 wk, respectively, PI. SRB51 was not recovered from saline-inoculated ground squirrels, deer mice, or voles at any time but was recovered from one saline-inoculated raven at necropsy, 7 wk PI, likely attributable to contact with SRB51-inoculated ravens in an adjacent aviary room. Spleen was the primary tissue site of colonization in ground squirrels, followed by the liver and reproductive organs. The results indicate oral exposure to SRB51 does not produce morbibity or mortality in ravens, ground squirrels, deer mice, or prairie voles.</span></p>","language":"English","publisher":"Wildlife

Landscape-level variables were measured and digitized at 200, 400 and 800 m from the perimeter of 38 200 m × 100 m strip transects. A mixture of field and landscape variables was associated with the density of savannah sparrow (</span><i>Passerculus sandwichensis</i><span>) and grasshopper sparrow (</span><i>Ammodramus savannarum</i><span>). Only landscape variables were associated with the density of bobolink (</span><i>Dolichonyx oryzivorus</i><span>), eastern meadowlark (</span><i>Sturnella magna</i><span>) and all birds that were grassland species of management concern. Field size was not an important predictor of bird density. Cover-type diversity of the surrounding area was commonly selected in the models for three species and all birds that were grassland species of management concern. Higher bird densities in the transects were associated with landscapes where the cover types were less diverse. Landscapes with low cover type diversity were dominated by grassland, pasture and hay. Field habitat, mean patch size of cover types and distance to woody vegetation were the next most common predictors of avian density. The density of some grassland birds increased as nonlinear woody features such as woodlots and shrub carrs decreased in patch size, decreased in total amount in the landscape and increased in distance from a transect. However, density of other species was positively associated with linear woody features such as the total amount and nearness of hedgerows. The composition of the surrounding landscape, at least out to 800 m, is important in grassland bird management.</span></p>","language":"English","publisher":"University of Notre

The efficiency and products of anaerobic MTBE biodegradation were dependent on the predominant terminal electron-accepting conditions. In the presence of substantial methanogenic activity, MTBE biodegradation was nominal and involved reduction of MTBE to the toxic product, tert-butyl alcohol (TBA). In the absence of significant methanogenic activity, accumulation of [14C]TBA generally decreased, and mineralization of [U-14C]MTBE to 14CO2 generally increased as the oxidative potential of the predominant terminal electron acceptor increased in the order of SO4, Fe(III), Mn(IV) < NO3 < O2. Microbial mineralization of MTBE to CO2 under Mn(IV)or SO4-reducing conditions has not been reported previously. The results of this study indicate that microorganisms inhabiting the sediments of streams and lakes can degrade MTBE effectively under a range of anaerobic terminal electron-accepting conditions. Thus, anaerobic bed sediment microbial processes may provide a significant environmental sink for MTBE in surface water systems throughout the United States.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es010794x","issn":"0013936X","usgsCitation":"Bradley, P., Chapelle, F.H., and Landmeyer, J., 2001, Effect of redox conditions on MTBE biodegradation in surface water Sediments: Environmental Science & Technology, v. 35, no. 23, p. 4643-4647, https://doi.org/10.1021/es010794x.","startPage":"4643","endPage":"4647","numberOfPages":"5","costCenters":[],"links":[{"id":232602,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207554,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es010794x"}],"volume":"35","issue":"23","noUsgsAuthors":false,"publicationDate":"2001-10-31","publicationStatus":"PW","scienceBaseUri":"505a05fde4b0c8380cd51078","contributors":{"authors":[{"text":"Bradley, P.

These catchments are characterized by a snowmelt-dominated hydrologic cycle, but range in the level of mining impact from little to severe. Zn concentrations increased during snowmelt along stream reaches with a history of mining, but were diluted by snowmelt where metals originated in widely disseminated pyrite in the host rock of the catchment. Inter-site differences in the relationship between Zn and sulfate, together with inter-annual variability in the timing and magnitude of peak Zn concentrations suggest that a portion of the Zn flush is retarded, perhaps through interaction with cation exchange sites in soil. Although Dissolved Organic Carbon (DOC) concentrations also increase during snowmelt, there was no indication that the export of Zn was facilitated by the flush of organic carbon.</span></p>","language":"English","publisher":"Springer-Verlag","doi":"10.1007/s002540100338","usgsCitation":"Brooks, P., McKnight, D., and Bencala, K.E., 2001, Annual maxima in Zn concentrations during spring snowmelt in streams impacted by mine drainage: Environmental Geology, v. 40, no. 11, p. 1447-1454, https://doi.org/10.1007/s002540100338.","productDescription":"8 p.

Northern Alaska, including the North Slope and adjacent Beaufort and Chukchi continental shelves, holds the lion's share of the total Alaskan endowment of more than 30 billion barrels (4.8 billion m<sup>3</sup>) of oil and natural-gas liquids plus nearly 200 trillion cubic feet (5.7 trillion m<sup>3</sup>) of natural gas. This geologically complex region includes prospective strata within passive-margin, rift, and foreland-basin sequences. Multiple source-rock zones have charged several regionally extensive petroleum systems. Extensional and compressional structures provide ample structural objectives. In addition, recent emphasis on stratigraphic traps has demonstrated significant resource potential in shelf and turbidite systems in Jurassic to Tertiary strata. Despite robust potential, northern Alaska remains a risky exploration frontier - a nexus of geologic complexity, harsh economic conditions, and volatile policy issues. Its role as a major petroleum province in this century will depend on continued technological innovations, not only in exploration and drilling operations, but also in development of huge, currently unmarketable natural-gas resources. Ultimately, policy decisions will determine whether exploration of arctic Alaska will proceed.</p>","language":"English","publisher":"American Association of Petroleum

Hybridization is a phenomenon long recognized in fishes (Hubbs, 1920, 1955; Schwarz, 1981), as well as in other plant and vertebrate taxa, despite some rather dogmatic proclamations to the contrary, e.g., comments made by David Starr Jordan at the beginning of the 20th century that the species “line” is rarely crossed in fishes (Clark Hubbs, personal communication). Since that time, interspecific genetic introgression has been well documented in many fish genera and species: Barbus (Berrebi and CattaneoBerrebi, 1993); Cyprinodon (Echelle and Connor, 1989; Dowling and DeMarais, 1993); Gambusia (Hubbs, 1959; Scribner and Avise, 1994); Esox (Wahl and Stein, 1993); Lepomis (Avise et al., 1984); Luxilus (Duvernell and Aspinwall, 1995); Morone (Harrell et al., 1993); Notropis (Dowling et al., 1989; Dowling and Hoeh, 1991); Oncorhynchus (Busack and Gall, 1981; Campton and Utter, 1985; Loudenslager et al., 1986; Leary et al., 1987; Forbes and Allendorf, 1991; Dowling and Childs, 1992); Salmo (Nyman, 1970; Wilkins et al., 1993; Giuffra et al., 1996; Hartley, 1996; Perez et al., 1999); Salvalinus (Hammar et al., 1991; Bernatchez et al., 1995; Baxter et al., 1997; Glemet et al., 1998; Wilson and Bernatchez, 1998); Sebastes (Seeb, 1988); Stizostedion (Billington et al., 1988). See also reviews in Campton (1987), Verspoor and Hammar (1991), Smith (1992), and Scribner et al. (2000). More recently, a number of investigations have documented not only first generation hybrids, but also subsequent generation introgressant hybrids (Bartley et al., 1990; Verspoor and Hammar, 1991). As a result, our views about species typology and hybrids continue to change.</p>","language":"English","publisher":"Kluwer Academic Publishers","doi":"10.1023/A:1016729132297","usgsCitation":"Epifanio, J., and Nielsen, J.L., 2001, The role of hybridization in the distribution, conservation and management of aquatic species: Symposium review: Reviews in Fish Biology and Fisheries, v. 10, no. 3, p. 245-251, https://doi.org/10.1023/A:1016729132297.","productDescription":"7 p.","startPage":"245","endPage":"251","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337399,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c3c946e4b0f37a93ee9b6b","contributors":{"authors":[{"text":"Epifanio, John","contributorId":139202,"corporation":false,"usgs":false,"family":"Epifanio","given":"John","email":"","affiliations":[],"preferred":false,"id":682613,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nielsen, Jennifer L.","contributorId":43722,"corporation":false,"usgs":true,"family":"Nielsen","given":"Jennifer","email":"","middleInitial":"L.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":682614,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Concentrations were determined from samples collected from 45 streams throughout the United States during 1993 to 1995 as part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA). Separate regression models were developed for each of six percentiles (10th, 25th, 50th, 75th, 90th, 95th) of the annual distribution of stream concentrations and for the annual time-weighted mean concentration. Estimates for the individual percentiles can be combined to provide an estimate of the annual distribution of concentrations for a given stream. Agricultural use of the herbicide in the watershed was a significant predictor in nearly all of the models. Several hydrologic and soil parameters also were useful in explaining the variability in concentrations of herbicides among the streams. Most of the regression models developed for estimation of concentration percentiles and annual mean concentrations accounted for 50 percent to 90 percent of the variability among streams. Predicted concentrations were nearly always within an order of magnitude of the measured concentrations for the model-development streams, and predicted concentration distributions reasonably matched the actual distributions in most cases. Results from application of the models to streams not included in the model development data set are encouraging, but further validation of the regression approach described in this paper is needed.","language":"English","publisher":"American Water Resources Association","doi":"10.1111/j.1752-1688.2001.tb03644.x","issn":"1093474X","usgsCitation":"Larson, S., and Gilliom, R.J., 2001,

Fine-grained, variably deformed sedimentary rocks deposited in a slope or basinal setting predominate and include varicolored (mainly red and green) argillite in the Simpson area, dark argillite and chert near Barrow, and widespread gray argillite. Chitinozoans of Middle-Late Ordovician and Silurian age occur in the dark argillite and chert unit. Sponge spicules and radiolarians establish a Phanerozoic age for the varicolored and gray argillite units, both of which contain local interbeds of chert-rich sandstone and silt-stone. Conglomerate and sandstone, also chert-rich but interbedded with mudstone and coal and of Early-Middle Devonian age, occur in the Topagoruk area; these strata formed in a fluvial environment. At East Teshekpuk, granite of probable Devonian age was penetrated. Brecciated, quartz-veined rock of uncertain protolith that may be part of the basement complex was encountered in the Ikpikpuk well. Seismic data indicate that angular unconformities truncate all sedimentary units of the basement complex in NPRA. Rocks correlative in age and lithofacies with the dark argillite and chert unit occur in the subsurface near Prudhoe Bay. Other argillite units in NPRA have similarities to basement rocks in the subsurface adjacent to ANWR and the Ordovician-Silurian Iviagik Group at Cape Lisburne, but lack the interbedded limestones found in the ANWR strata, and are less metamorphosed than, and compositionally distinct from, the Iviagik. The Topagoruk conglomerate and the East Teshekpuk granite resemble the Ulungarat formation and the Okpilak batholith, respectively, in the northeastern Brooks Range. </p>","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.2110/cor.01.01.0201","usgsCitation":"Dumoulin, J.A., 2001, Lithologies of the basement complex (Devonian and older) in the National Petroleum Reserve - Alaska: SEPM Core Workshop Notes, v. 21, p. 201-214, https://doi.org/10.2110/cor.01.01.0201.","productDescription":"14 p.","startPage":"201","endPage":"214","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337406,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -164.35546875,\n              68.39918004344189\n            ],\n            [\n              -149.58984375,\n              68.39918004344189\n            ],\n            [\n              -149.58984375,\n              71.18775391813158\n            ],\n            [\n              -164.35546875,\n              71.18775391813158\n            ],\n            [\n              -164.35546875,\n              68.39918004344189\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"21","publicComments":"Volume Title: Petroleum Plays and Systems in the National Petroleum Reserve - Alaska","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c50918e4b0f37a93ee9ce2","contributors":{"editors":[{"text":"Houseknecht, David W. 0000-0002-9633-6910 dhouse@usgs.gov","orcid":"https://orcid.org/0000-0002-9633-6910","contributorId":645,"corporation":false,"usgs":true,"family":"Houseknecht","given":"David","email":"dhouse@usgs.gov","middleInitial":"W.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":683697,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Dumoulin, Julie A. 0000-0003-1754-1287 dumoulin@usgs.gov","orcid":"https://orcid.org/0000-0003-1754-1287","contributorId":203209,"corporation":false,"usgs":true,"family":"Dumoulin","given":"Julie","email":"dumoulin@usgs.gov","middleInitial":"A.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":683696,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

A set of 13 explanatory variables was derived from these characteristics, and variables that have a significant influence were identified using logistic regression (LR). Multivariate LR models based on more than 900 sampled wells predicted the probability of exceeding 4 mg/L of nitrate in ground water. The final LR model consists of the following variables: (1) nitrogen fertilizer loading (p-value = 0.012); (2) percent cropland-pasture (p &lt; 0.001); (3) natural log of population density (p &lt; 0.001); (4) percent well-drained soils (p = 0.002); (5) depth to the seasonally high water table (p = 0.001); and (6) presence or absence of a fracture zone within an aquifer (p = 0.002). Variables 1–3 were compiled within circular, 500 m radius areas surrounding sampled wells, and variables 4–6 were compiled within larger areas representing targeted land use and aquifers of interest. Fitting criteria indicate that the full logistic-regression model is highly significant (p &lt; 0.001), compared with an intercept-only model that contains none of the explanatory variables. A goodness-of-fit test indicates that the model fits the data well, and observed and predicted probabilities of exceeding 4 mg/L nitrate in ground water are strongly correlated (r</span><sup>2</sup><span>= 0.971). Based on the multivariate LR model, vulnerability of ground water to contamination by nitrate depends not on any single factor but on the combined, simultaneous influence of factors representing

Two disease challenge experiments were performed. The first experimental challenge resulted in no mortality; however, significant strain and challenge treatment effects were detected at Day 16 post-challenge. Strain differences in plasma lysozyme activity were found in pre-challenge samples. The second challenge experiment compared the same strains of coho salmon following immersion challenges in different doses of Vang. The fish were sampled at Days 0, 2, 7, and 18 post-challenge and mortality, plasma lysozyme, and anterior kidney phagocyte respiratory burst activity were compared. There were significant strain differences in mortality in the high dose group. The more disease-resistant strain was found to have higher levels of plasma lysozyme and anterior kidney phagocyte respiratory burst activity. These strain differences were detected at various times in the lethal (high dose) and non-lethal challenge groups. There was a clear relationship between the enhanced survival of the more disease-resistant strain and a more sustained, elevated non-specific immune response following the experimental disease challenges. The results of this study suggest that the basis for strain differences in innate disease resistance is related to the ability of the fish to respond quickly to the initial infection and to maintain the response until the infection is quelled.</span></p>","language":"English","publisher":"Inter-Research","doi":"10.3354/dao047039","usgsCitation":"Balfry, S.K., Maule, A.G., and Iwama, G.K., 2001, Coho salmon Oncorhynchus kisutch strain differences in disease resistance and non-specific immunity, following immersion challenges with Vibrio anguillarum: Diseases of Aquatic Organisms, v. 47, no. 1, p. 39-48, https://doi.org/10.3354/dao047039.","productDescription":"10 p.","startPage":"39","endPage":"48","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":478898,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/dao047039","text":"Publisher Index Page"},{"id":320377,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"47","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5719f9afe4b071321fe22bb2","contributors":{"authors":[{"text":"Balfry, Shannon K.","contributorId":168808,"corporation":false,"usgs":false,"family":"Balfry","given":"Shannon","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":627357,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Maule, Alec G. amaule@usgs.gov","contributorId":2606,"corporation":false,"usgs":true,"family":"Maule","given":"Alec","email":"amaule@usgs.gov","middleInitial":"G.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":627358,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Iwama, George K.","contributorId":168809,"corporation":false,"usgs":false,"family":"Iwama","given":"George","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":627359,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In common are six multispectral bands with a 30-m ground-projected instantaneous field of view (GIFOV). However, the thermaL-IR (TIR) band now has a 60-m GIFOV, instead of 120-m. Also, a 15-m panchromatic band has been added. The artificial neural network (NN) image sharpening method described here uses data from the higher spatial resolution ETM+ bands to enhance (sharpen) the spatial resolution of the TIR imagery. It is based on an assumed correlation over multiple scales of resolution, between image edge contrast patterns in the TIR band and several other spectral bands. A multilayer, feedforward NN is trained to approximate TIR data at 60m, given degraded (from 30-m to 60-m) spatial resolution input from spectral bands 7, 5, and 2. After training, the NN output for full-resolution input generates an approximation of a TIR image at 30-m resolution. Two methods are used to degrade the spatial resolution of the imagery used for NN training, and the corresponding sharpening results are compared. One degradation method uses a published sensor transfer function (TF) for Landsat 5 to simulate sensor coarser resolution imagery from higher resolution imagery. For comparison, the second degradation method is simply Gaussian low pass filtering and subsampling, wherein the Gaussian filter approximates the full width at half maximum amplitude characteristics of the TF-based spatial filter. Two fixed-size NNs (that is, number of weights and processing elements) were trained separately with the degraded resolution data, and the sharpening results compared. The comparison evaluates the relative influence of the degradation technique employed and whether or not it is desirable to incorporate a sensor TF model. Preliminary results indicate some improvements for the sensor model-based technique. Further evaluation using a higher resolution reference image and strict application of sensor model to data is recommended.","largerWorkTitle":"Proceedings of SPIE - The International Society for Optical Engineering","conferenceTitle":"Visual Information Processing X","conferenceDate":"19 April 2001 through 20 April 2001","conferenceLocation":"Orlando,FL","language":"English","doi":"10.1117/12.438256","issn":"0277786X","usgsCitation":"Lemeshewsky, G., and Schowengerdt, R., 2001, Landsat 7 thermal-IR image sharpening using an artificial neural network and sensor model, <i>in</i> Proceedings of SPIE - The International Society for Optical Engineering, v. 4388, Orlando,FL, 19 April 2001 through 20 April 2001, p. 181-192, https://doi.org/10.1117/12.438256.","startPage":"181","endPage":"192","numberOfPages":"12","costCenters":[],"links":[{"id":207607,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1117/12.438256"},{"id":232703,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4388","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a43cde4b0c8380cd66623","contributors":{"editors":[{"text":"Park S.K.Rahman Z.Schowengerdt R.A.","contributorId":128439,"corporation":true,"usgs":false,"organization":"Park S.K.Rahman Z.Schowengerdt R.A.","id":536503,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Lemeshewsky, G.P.","contributorId":106927,"corporation":false,"usgs":true,"family":"Lemeshewsky","given":"G.P.","affiliations":[],"preferred":false,"id":398403,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schowengerdt, R.A.","contributorId":83707,"corporation":false,"usgs":true,"family":"Schowengerdt","given":"R.A.","affiliations":[],"preferred":false,"id":398402,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Plague epizootics frequently kill >99% of prairie dogs in infected colonies. Although epizootics of sylvatic plague occur throughout most of the range of prairie dogs in the United States and are well described, long-term maintenance of plague in enzootic rodent species is not well documented or understood. We review dynamics of plague in white-tailed (Cynomys leucurus), Gunnison's (C. gunnisoni), and black-tailed (C. ludovicianus) prairie dogs, and their rodent and flea associates. We use epidemiologic concepts to support an enzootic hypothesis in which the disease is maintained in a dynamic state, which requires transmission of Y. pestis to be slower than recruitment of new susceptible mammal hosts. Major effects of plague are to reduce colony size of black-tailed prairie dogs and increase intercolony distances within colony complexes. In the presence of plague, black-tailed prairie dogs will probably survive in complexes of small colonies that are usually >3 km from their nearest neighbor colonies.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1644/1545-1542(2001)082<0894:ICOSPI>2.0.CO;2","issn":"00222372","usgsCitation":"Cully, J., and Williams, E., 2001, Interspecific comparisons of sylvatic plague in prairie dogs: Journal of Mammalogy, v. 82, no. 4, p. 894-905, https://doi.org/10.1644/1545-1542(2001)082<0894:ICOSPI>2.0.CO;2.","startPage":"894","endPage":"905","numberOfPages":"12","costCenters":[],"links":[{"id":207632,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/1545-1542(2001)082<0894:ICOSPI>2.0.CO;2"},{"id":232746,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"82","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3daae4b0c8380cd6373e","contributors":{"authors":[{"text":"Cully, J.F.

Molecular transformation involves the movement of discrete amounts of DNA into cells, the expression of genes on the transported DNA, and the sustainable replication of the transforming DNA. The ability to transform fungi is dependent on the stable replication and expression of genes located on the transforming DNA. Three phenomena observed in bacteria, that is, competence, plasmids, and restriction enzymes to facilitate cloning, were responsible for the development of molecular transformation in fungi. Initial transformation success with filamentous fungi, involving the complementation of auxotrophic mutants by exposure to sheared genomic DNA or RNA from wt isolates, occurred with low transformation efficiencies. In addition, it was difficult to retrieve complementing DNA fragments and isolate genes of interest. This prompted the development of transformation vectors and methods to increase efficiencies. The physiological studies performed with fungi indicated that the cell wall could be removed to generate protoplasts. It was evident that protoplasts could be transformed with significantly greater efficiencies than walled cells.</span></p>","language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam","doi":"10.1016/S1874-5334(01)80010-1","usgsCitation":"Gold, S.E., Duick, J.W., Redman, R.S., and Rodriguez, R.J., 2001, Molecular transformation, gene cloning, and gene expression systems for filamentous fungi: Applied Mycology and Biotechnology, v. 1, p. 199-238, https://doi.org/10.1016/S1874-5334(01)80010-1.","productDescription":"40 p.","startPage":"199","endPage":"238","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":323970,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"576913dae4b07657d19ff1b4","contributors":{"authors":[{"text":"Gold, Scott E.","contributorId":168815,"corporation":false,"usgs":false,"family":"Gold","given":"Scott","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":627377,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Duick, John W.","contributorId":168816,"corporation":false,"usgs":false,"family":"Duick","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":627378,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Redman, Regina S. 0000-0001-5108-7570","orcid":"https://orcid.org/0000-0001-5108-7570","contributorId":75829,"corporation":false,"usgs":true,"family":"Redman","given":"Regina","email":"","middleInitial":"S.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":false,"id":627379,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rodriguez, Rusty J.","contributorId":62497,"corporation":false,"usgs":true,"family":"Rodriguez","given":"Rusty","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":627380,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

For six years, we recaptured wild subyearling chinook salmon smolts, which had been previously PIT tagged in the Snake River, to genetically determine if the fish were offspring of spring and summer (hereafter, spring/summer), or fall chinook salmon. Springfall chinook salmon comprised over 10% of the samples of recaptured smolts in five of six years. For these five years, we used discriminant analysis to determine run membership of PIT-tagged smolts that were not recaptured (i.e., not sampled for genetic identification). Accuracy of the discriminant analysis models, based on genetically identified smolts, varied between 75 and 85%. After using discriminant analysis to classify run membership for each PIT-tagged smolt that was not genetically identified, we compared early life history attributes between fall and spring/summer chinook salmon and calculated annual run composition. The life history attributes we studied overlapped, but spring/summer chinook salmon reared along the shoreline of the free-flowing Snake River earlier, were larger, and began seaward migration earlier than fall chinook salmon. Spring/summer chinook salmon made up from 15.1 to 44.4% of the tagged subyearling smolts that were detected passing Lower Granite Dam. As a result, the presence of spring/summer chinook salmon makes migration timing for the fall chinook salmon seem earlier and more protracted than is the case.

The data sets are analyzed using principal component analysis to examine the temporal variability of the flows which create the residual circulation. It is seen that in this periodically and partially stratified estuary the residual flows are created through a series of pulses with strong variability at the 24‐hour timescale, through the interaction of shear, stratification and mixing. This interaction is captured through the use of a dimensionless number, the horizontal Richardson number (</span><i>Ri</i><sub><i>x</i></sub><span>), which is developed to examine the&nbsp;</span><i>local</i><span>&nbsp;balance between the stratifying and destratifying forces at the tidal timescale. It is seen that&nbsp;</span><i>Ri</i><sub><i>x</i></sub><span>&nbsp;is a valuable parameter in predicting the onset of the residual‐creating events, with a threshold value of ≈3 on ebb tides. This critical value is argued to be a threshold, above which the stratification and shear flow create a feedback effect, each further intensifying the other. This feedback results in a highly variable exchange flow which creates the estuarine residual in intermittent pulses rather than as a steady flow. Although typically attributed to baroclinic forcing, an argument is made that these pulses of residual‐creating exchange flow could be created by barotropic forcing in the presence of variable stratification which is asymmetric between flood and ebb tides. This result poses a great challenge for turbulence modeling, as the timing and magnitude of stratification and shear must be correctly simulated on the tidal timescale in order to reproduce the effects seen in the data sets presented.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/2000JC000576","issn":"01480227","usgsCitation":"Stacey, M., Burau, J., and Monismith, S., 2001, Creation of residual flows in a partially stratified estuary: Journal of Geophysical Research C: Oceans, v. 106, no.

Better predictions of strong ground shaking will therefore require additional geologic data and more comprehensive computer simulations of individual earthquakes.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/fs00101","usgsCitation":"Field, E., Jones, L., Jordan, T., Benthien, M., and Wald, L., 2001, Earthquake shaking — Finding the \"hot spots\" (Online version 1.0.): U.S. Geological Survey Fact Sheet 001-01, 2 p., https://doi.org/10.3133/fs00101.","productDescription":"2 p.","costCenters":[],"links":[{"id":122849,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_001_01.jpg"},{"id":404281,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_34761.htm","linkFileType":{"id":5,"text":"html"}},{"id":8982,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/2001/fs001-01/","linkFileType":{"id":5,"text":"html"}}],"edition":"Online version 1.0.","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a52e4b07f02db62ace7","contributors":{"authors":[{"text":"Field, Edward H. 0000-0001-8172-7882 field@usgs.gov","orcid":"https://orcid.org/0000-0001-8172-7882","contributorId":1165,"corporation":false,"usgs":true,"family":"Field","given":"Edward H.","email":"field@usgs.gov","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":150756,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, Lucile","contributorId":9639,"corporation":false,"usgs":true,"family":"Jones","given":"Lucile","affiliations":[],"preferred":false,"id":150757,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jordan, Tom","contributorId":44524,"corporation":false,"usgs":true,"family":"Jordan","given":"Tom","affiliations":[],"preferred":false,"id":150759,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Benthien, Mark","contributorId":32146,"corporation":false,"usgs":true,"family":"Benthien","given":"Mark","affiliations":[],"preferred":false,"id":150758,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wald, Lisa","contributorId":60196,"corporation":false,"usgs":true,"family":"Wald","given":"Lisa","affiliations":[],"preferred":false,"id":150760,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
