A simple method was developed for determining florfenicol concentration in a small volume (250 μl) of plasma from five phylogenetically diverse species of freshwater fish. Florfenicol was isolated from the plasma matrix through C18 solid-phase extraction and quantified by reversed-phase high-performance liquid chromatography with UV detection. The accuracy (84–104%), precision (%RSD⩽8), and sensitivity (quantitation limit <30 ng/ml) of the method indicate its usefulness for conducting pharmacokinetic studies on a variety of freshwater fish.

Although no instrumental data are available for either the mainshocks or the aftershocks, available historical accounts do provide information that can be used to estimate magnitudes and locations for the large events. In this article we investigate two of the largest aftershocks: one near dawn following the first mainshock on 16 December 1811, and one near midday on 17 December 1811. We reinterpret original felt reports to obtain a set of 48 and 20 modified Mercalli intensity values of the two aftershocks, respectively. For the dawn aftershock, we infer a Mw of approximately 7.0 based on a comparison of its intensities with those of the smallest New Madrid mainshock. Based on a detailed account that appears to describe near-field ground motions, we further propose a new fault rupture scenario for the dawn aftershock. We suggest that the aftershock had a thrust mechanism and occurred on a southeastern limb of the Reelfoot fault. For the 17 December 1811 aftershock, we infer a MW of approximately 6.1 ± 0.2. This value is determined using the method of Bakun et al. (2002), which is based on a new calibration of intensity versus distance for earthquakes in central and eastern North America. The location of this event is not well constrained, but the available accounts suggest an epicenter beyond the southern end of the New Madrid Seismic Zone.

Wet weight concentrations of TCDD and PCBs in eggs were at background levels and highest in the piscivorous hooded merganser (Lophodytes cucullatus; geometric mean=7 pg/g TCDD and 0.92 μg/g PCBs) and lowest in the omnivorous wood duck (Aix sponsa) (<1 pg/g and 0.07 μg/g); concentrations in eggs of the insectivorous tree swallow (Tachycineta bicolor) were intermediate (<1 pg/g and 0.33 μg/g). Positive accumulation rates of TCDD (8–19 pg/day) and PCBs (0.4–0.7 μg/day) in tree swallow nestlings suggest that the Wisconsin River is the source of these contaminants for tree swallow nestlings. The lower representation of trichlorobiphenyls and tetrachorobiphenyls in hooded merganser eggs compared to wood duck or tree swallow eggs suggests that the hooded merganser or its diet has a greater ability to metabolize lower-numbered PCB congeners than wood ducks or tree swallows.

The process of creating these networks is called river network upscaling and consists of lowering the resolution of already available fine networks to make them compatible with GCMs. Fine‐resolution river networks have a level of detail appropriate for analysis at the watershed scale but are too intensive for global hydrologic studies. A river network upscaling algorithm, which processes fine‐resolution digital elevation models to determine the flow directions that best describe the flow patterns in a coarser user‐defined scale, is presented. The objectives of this study were to develop an algorithm that advances the previous work in the field by being applicable at a global scale, allowing for the upscaling to be performed in a projected environment, and generating evenly distributed flow directions.

Great Blue Herons preferred large waterbodies (350 ha), whereas Great Egrets fed most often at small ponds (<25 ha). Forty-nine percent of Great Blue Herons used wetlands 301-400 hectares in size and 83% of Great Egrets fed in wetlands <100 ha in size. Great Blue Herons selected large wetlands more often than expected both at the regional (30-km radius) and local (4-km radius) scales. Habitat use by Great Egrets was in proportion to availability at the regional scale, but they selected smaller wetlands for feeding more often than expected at a local scale. The median flight distance of Great Blue Herons was 2.7 km, similar to distances reported elsewhere. Great Egrets flew farther to feeding sites than Great Blue Herons, and flew farther (median = 13.5 km) than reported in other geographic areas.

The few early studies that did much more than mention their existence began in the 1930s and continued into the early 1960s, focusing primarily on distributional surveys and taxonomic analyses. Starting in the 1980s the Baja California rainbow trout became the subject of more detailed studies, but very little remains known of mainland trouts of the Sierra Madre Occidental. We review earlier studies and report on our own collections and observations made between 1975 and 2000. We present newly discovered historical evidence that leads us to conclude that a \"lost\" cutthroat trout, a lineage not previously known from Mexico, was collected more than a century ago from headwaters of the Ri??o Conchos (a major tributary of the Rio Grande (= Ri??o Bravo)), a basin not previously considered to harbor a native trout. We review the last century of regional natural resource management and discuss our own observations of trout habitats. Impacts of logging, road building and overgrazing are widespread and expanding. Many streams suffer from heavy erosion, siltation and contamination, and though long-term hydrologic data are generally not available, there is evidence of decreased discharge in many streams. These problems appear related to region-wide land management practices as well as recent regional drought. Trout culture operations using exotic rainbow trout have rapidly proliferated throughout the region, threatening genetic introgression and/or competition with native forms and predation on them. Knowledge of distribution, abundance, relationships and taxonomy, not to mention ecology and population biology, of native trouts of the Sierra Madre Occidental remains inadequate. Vast areas of most mainland drainages are still unexplored by fish collectors, and even rudimentary information regarding basic biology, ecology and population structure of stocks remains lacking. Concentrated exploration, research and management of this long overlooked and undervalued resource are all urgently needed. The history of natural resources exploitation that placed so many native trouts of the western United States on threatened and endangered species lists is repeating itself in the Sierra Madre Occidental. Without concentrated action and development of region-wide socio-economic solutions for current, largely non-sustainable resource management practices, native Mexican trout gene pools will soon be in grave danger of extinction.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Reviews in Fish Biology and Fisheries","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1025062415188","issn":"09603166","usgsCitation":"Hendrickson, D., Perez, H., Findley, L., Forbes, W., Tomelleri, J., Mayden, R.L., Nielsen, J., Jensen, B., Campos, G., Romero, A., van der Heiden, A., Camarena, F., and Garcia de Leon, F., 2002, Mexican native trouts: A review of their history and current systematic and conservation status: Reviews in Fish Biology and Fisheries, v. 12, no. 2-3, p. 273-316, https://doi.org/10.1023/A:1025062415188.","startPage":"273","endPage":"316","numberOfPages":"44","costCenters":[],"links":[{"id":207184,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1025062415188"},{"id":231905,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5626e4b0c8380cd6d3a3","contributors":{"authors":[{"text":"Hendrickson, D.A.","contributorId":29222,"corporation":false,"usgs":true,"family":"Hendrickson","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":399859,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Perez, H.E.","contributorId":92109,"corporation":false,"usgs":true,"family":"Perez","given":"H.E.","email":"","affiliations":[],"preferred":false,"id":399864,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Findley, L.T.","contributorId":92110,"corporation":false,"usgs":true,"family":"Findley","given":"L.T.","email":"","affiliations":[],"preferred":false,"id":399865,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Forbes, W.","contributorId":60913,"corporation":false,"usgs":true,"family":"Forbes","given":"W.","email":"","affiliations":[],"preferred":false,"id":399860,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Tomelleri, J.R.","contributorId":77418,"corporation":false,"usgs":true,"family":"Tomelleri","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":399862,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mayden, Richard L.","contributorId":12746,"corporation":false,"usgs":true,"family":"Mayden","given":"Richard","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":399857,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Nielsen, J.L.","contributorId":105665,"corporation":false,"usgs":true,"family":"Nielsen","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":399869,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Jensen, B.","contributorId":73877,"corporation":false,"usgs":true,"family":"Jensen","given":"B.","email":"","affiliations":[],"preferred":false,"id":399861,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Campos, G.R.","contributorId":91745,"corporation":false,"usgs":true,"family":"Campos","given":"G.R.","email":"","affiliations":[],"preferred":false,"id":399863,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Romero, A.V.","contributorId":104343,"corporation":false,"usgs":true,"family":"Romero","given":"A.V.","email":"","affiliations":[],"preferred":false,"id":399868,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"van der Heiden, A.","contributorId":99434,"corporation":false,"usgs":true,"family":"van der Heiden","given":"A.","email":"","affiliations":[],"preferred":false,"id":399867,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Camarena, F.","contributorId":21418,"corporation":false,"usgs":true,"family":"Camarena","given":"F.","email":"","affiliations":[],"preferred":false,"id":399858,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Garcia de Leon, F.J.","contributorId":96536,"corporation":false,"usgs":true,"family":"Garcia de Leon","given":"F.J.","affiliations":[],"preferred":false,"id":399866,"contributorType":{"id":1,"text":"Authors"},"rank":13}]}} ,{"id":1000933,"text":"1000933 -

It was hypothesised that combinations of an environmental contaminant (mercuric chloride or Aroclor 1254) and an immunomodulatory agent (bacterial endotoxin or cortisol) might interact to produce a greater toxicity than that of the environmental contaminant alone at concentrations typically encountered in piscine blood and other tissues. Thus lake trout thymocytes were isolated and treated with mercuric chloride or Aroclor 1254 in the presence and absence of cortisol or lipopolysaccharide. Incubations were performed for 6 or 20 h at 4° C or 10° C. Lipopolysaccharide did not affect the toxicity of either contaminant. In contrast, cortisol enhanced the toxicity of both environmental contaminants. Hence, stressors that lead to increased cortisol production, but not lipopolysaccharide directly, may increase the toxicity of mercury and Aroclor 1254 to lake trout thymocytes.

To study the effects of shock pressures on thermal infrared spectra of these minerals, we performed shock recovery experiments on orthopyroxenite and anorthosite samples from the Stillwater Complex (Montana) over peak pressures from 17 to 63 GPa. We acquired emissivity and hemispherical reflectance spectra (350–1400 cm−1; ∼7–29 μm) of both coherent chips and fine-grained powders of shocked and unshocked samples. These spectra are more directly comparable to remotely sensed data of Mars (e.g., TES) than previously acquired absorption or transmission spectra of shocked minerals. The spectra of experimentally shocked feldspar show systematic changes with increasing pressure due to depolymerization of the silica tetrahedra. For the spectra of chips, this includes the disappearance of small bands in the 500–650 cm−1 region and a strong band at 1115 cm−1, and changes in positions of a strong band near 940 cm−1 and the Christiansen feature near 1250 cm−1. Spectra of the shocked powders show the gradual disappearance of a transparency feature near 830 cm−1. Fewer changes are observed in the pyroxene spectra at pressures as high as 63 GPa. Spectra of experimentally shocked minerals will help identify more precisely the mineralogy of rocks and soils not only from TES but also from Mars instruments such as miniTES and THEMIS.

Previous work suggests that bluegills large enough to avoid predators will select habitats based on foraging profitability. However, these studies focused on smaller fish (<150 mm standard length) in laboratory experiments or in natural systems with distinct vegetated and open-water habitats. Our objective was to use radio telemetry to determine monthly and diel vegetation selection by larger (>200 mm total length [TL]) bluegills in a shallow (mean depth = 1.2 m), 332-ha, natural lake (Pelican Lake, Nebraska) with both emergent and submergent vegetation distributed throughout. A total of 78 bluegills (200-273 mm TL) were implanted with radio transmitters and relocated daily for 6 d per month (April-September); up to 20 of the tagged fish were relocated every 2 h for a 24-h period once each month. Regardless of diel period, bluegills used open-water, emergent vegetation, submergent vegetation, and mixed emergent - submergent vegetation habitat types in similar proportions. During April, June, and July, male bluegills positively selected emergent vegetation, whereas female bluegills showed no vegetation selection preference during any month. Throughout the study period, bluegills never avoided open-water habitats, suggesting that larger individuals may continue to use open-water habitats in proportion to their availability. In addition, emergent vegetation appeared to be important, particularly for male bluegills. Although the mechanism for the positive selection of emergent vegetation by males was unclear, the protection or enhancement of such habitats may facilitate the preservation of quality bluegill populations in shallow lakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/1548-8659(2002)131<1131:SADHSB>2.0.CO;2","issn":"00028487","usgsCitation":"Paukert, C., and Willis, D., 2002, Seasonal and diel habitat selection by bluegills in a shallow natural lake: Transactions of the American Fisheries Society, v. 131, no. 6, p. 1131-1139, https://doi.org/10.1577/1548-8659(2002)131<1131:SADHSB>2.0.CO;2.","startPage":"1131","endPage":"1139","numberOfPages":"9","costCenters":[],"links":[{"id":207079,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8659(2002)131<1131:SADHSB>2.0.CO;2"},{"id":231677,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"131","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b886ae4b08c986b31696d","contributors":{"authors":[{"text":"Paukert, C.P.","contributorId":10151,"corporation":false,"usgs":true,"family":"Paukert","given":"C.P.","email":"","affiliations":[],"preferred":false,"id":399981,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Willis, D.W.","contributorId":56179,"corporation":false,"usgs":true,"family":"Willis","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":399982,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70024084,"text":"70024084 - 2002 - Composition of cavity-nesting bird communities in montane aspen woodland fragments: The roles of landscape context and forest structure","interactions":[],"lastModifiedDate":"2021-12-23T16:29:05.779428","indexId":"70024084","displayToPublicDate":"2002-01-01T00:00:00","publicationYear":"2002","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1318,"text":"Condor","active":true,"publicationSubtype":{"id":10}},"title":"Composition of cavity-nesting bird communities in montane aspen woodland fragments: The roles of landscape context and forest structure","docAbstract":"We compared cavity-nesting bird communities in aspen (Populus tremuloides) woodland fragments classified on the basis of vegetation structure (tree density) and landscape context (surrounding vegetation). We found very few cavity nesters in fragments predominantly surrounded by forests. Fragments adjacent to meadows contained more species and a greater abundance of cavity nesters. Species richness and abundance were higher in sparsely than in densely treed meadow fragments. Because secondary cavity nesters are often limited by cavity availability, we augmented natural cavities with nest boxes. Although only five boxes contained bird nests, these were all in sparse aspen fragments predominantly surrounded by meadows. However, we found 25 northern flying squirrel (Glaucomys sabrinus) nests in boxes, none of which were in sparse meadow fragments. In addition to high-lighting the importance of landscape context in avian and mammalian habitat relationships, our results suggest that predator or competitor interactions may help structure this cavity-nester community.

Only 6% (2 of 36) of females wintered within the wintering area of the other breeding population. Both breeding populations wintered in the closest available ice-free habitat, perhaps to minimize migratory distance. Two Beaufort Sea females wintered in areas used by Yukon-Kuskokwim Delta females, implying potential gene flow among breeding areas. Yet, we conclude that these two populations are largely geographically isolated throughout the annual cycle and the environmental factors influencing survival and reproduction likely differ between these groups of birds. Thus, regardless of the potential gene flow among breeding populations, we suggest that birds from these two breeding areas should be managed as separate populations. ??

A new approach of evaluating a fish bioenergetics model in the field involves field estimation of the efficiency with which the fish retains PCBs from its food. We used diet information, PCB determinations in both chinook salmon and their prey, and bioenergetics modeling to generate a field estimate of the efficiency with which Lake Michigan chinook salmon retain PCBs from their food. Our field estimate is the most reliable field estimate to date because (a) the estimate was based on a relatively high number (N = 142) of PCB determinations for chinook salmon from Wisconsin waters of Lake Michigan in 1985, (b) a relatively long time series (1978−1988) of detailed observations on chinook salmon diet in Lake Michigan was available, and (c) the estimate incorporated new information from analyses of chinook salmon age and growth during the 1980s and 1990s in Lake Michigan. We estimated that chinook salmon from Lake Michigan retain 53% of the PCBs that are contained within their food.

The 26-km-long, N86°W-trending Sakarya fault segment (SFS) extends from the Sapanca releasing step-over in the west to near the town of Akyazi in the east. The SFS emerges from Lake Sapanca as two distinct fault traces that rejoin to traverse the Adapazari Plain to Akyazi. Offsets were measured across 88 cultural and natural features that cross the fault, such as roads, cornfield rows, rows of trees, walls, rails, field margins, ditches, vehicle ruts, a dike, and ground cracks. The maximum displacement observed for the İzmit earthquake (∼5.1 m) was encountered on this segment. Dextral displacement for the SFS rises from less than 1 m at Lake Sapanca to greater than 5 m near Arifiye, only 3 km away. Average slip decreases uniformly to the east from Arifiye until the fault steps left from Sagir to Kazanci to the N75°W, 6-km-long Akyazi strand, where slip drops to less than 1 m. The Akyazi strand passes eastward into the Akyazi Bend, which consists of a high-angle bend (18°-29°) between the Sakarya and Karadere fault segments, a 6-km gap in surface rupture, and high aftershock energy release. Complex structural geometries exist between the İzmit, Düzce, and 1967 Mudurnu fault segments that have arrested surface ruptures on timescales ranging from 30 sec to 88 days to 32 yr. The largest of these step-overs may have acted as a rupture segmentation boundary in previous earthquake cycles.

A Core Operations Team (COT), sequestered at the Jet Propulsion Laboratory without knowledge of test site location, prepared command sequences and interpreted data acquired by the rover. Instrument sensors included a stereo panoramic camera, navigational and hazard-avoidance cameras, a color microscopic imager, an infrared point spectrometer, and a rock coring drill. The COT designed command sequences, which were relayed by satellite uplink to the rover, and evaluated instrument data. Using aerial photos and Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) data, and information from the rover sensors, the COT inferred the geology of the landing site during the 18 sol mission, including lithologic diversity, stratigraphic relationships, environments of deposition, and weathering characteristics. Prominent lithologic units were interpreted to be dolomite-bearing rocks, kaolinite-bearing altered felsic volcanic materials, and basalt. The color panoramic camera revealed sedimentary layering and rock textures, and geologic relationships seen in rock exposures. The infrared point spectrometer permitted identification of prominent carbonate and kaolinite spectral features and permitted correlations to outcrops that could not be reached by the rover. The color microscopic imager revealed fine-scale rock textures, soil components, and results of coring experiments.

Further sampling in the bay in 2001 revealed infections on 7 additional species (bluegill, Lepomis macrochirus; carp, Cyprinus carpio; channel catfish, Ictalurus punctatus; goldfish, Carassius auratus; green sunfish, Lepomis cyanellus; rock bass, Ambloplites rupestris; and smallmouth bass, Micropterus dolomieu). An additional 21 species examined in 2001 were devoid of the parasite. A limited collection of fish from Lake Superior (n = 8) and Lake Michigan (n = 46) in 1994 showed no infection. Neoergasilus japonicus is most frequently found attached to the dorsal fin and, in decreasing frequency, on the anal, tail, pelvic, and pectoral fins. Prevalence generally ranged from 15 to 70 and intensity from 1 to 10. The greatest number of copepods on a single host was 44. The copepod Neoergasilus japonicus appears to disperse over long distances rather quickly, spreading across Europe in 20 yr and then moving on to North America over a span of 10 yr. Its main vehicle of transport and introduction into the Great Lakes is probably exotic fish hosts associated with the fish-culture industry.

The degraded condition presents numerous opportunities for pollution mitigation and ecosystem restoration. In many areas of the river and watershed, biological communities are characterized by low diversity and pollution-tolerant organisms. By establishing programs of nonnative species control, prescribed burning, sediment removal, wetland establishment and extirpated species re-introduction, the Grand Calumet can be improved to reflect some of its natural history. The dredging plan for the river presents an opportunity to coordinate simultaneous improvement and restoration plans.

In the Detroit River fish, carp and large mouth bass, the congener patterns were dominated by the 2,2′,4,4′-tetrabromo (BDE-47) congener; however, in Des Plaines River carp the dominant isomers were the heptabromo congeners BDE-181 and BDE-183 and lesser amounts of another heptabromo congener, BDE-190, and two hexabromo congeners, BDE-154 and BDE-153. Three possible sources exist for these less-commonly identified PBDE congeners: (a) waste discharge from manufacturing or discarded products near the river, (b) public owned treatment work (POTW) effluents which constitute more than 75% of the flow in the Des Plaines River, (c) or formation of these congeners by debromination of in-place deposits of decabromodiphenyl ether. Average concentration totals (sum of concentrations for seven of the dominant PBDE congeners) were similar on a wet weight bases for the carp (5.39 ng/g wet weight) and large mouth bass (5.25 ng/g) in the Detroit River samples; however, the bass were significantly higher, ρ=0.01, when compared on a lipid basis (bass-163 ng/g vs. carp-40.5 ng/g lipid weight). Some of the PBDE congeners were positively correlated with increasing lipid levels in both fish species. Average total PBDE concentrations in the carp from the Des Plaines River (12.48 ng/g wet weight) were significantly higher, ρ=0.01, than in carp from the Detroit River. The residues were isolated using standard organochlorine methods for fish and analyzed using gas chromatography/mass spectrometry-negative chemical ionization methods.

This field is the first CBM field in Texas (Fig. 1). The field is producing from bituminous coal in the Cretaceous Olmos Formation that outcrops to the west and dips easterly towards the Gulf Coast. The CBM field was developed in coalbeds whose general structure was known from log top data in pre-existing oil and gas wells drilled throughout the basin (Fig. 2). These preliminary data showed a large area of coal above 2000 ft depth with net coal thicknesses in the 5 to 30 ft range. Subsequently, TXCO and the USGS formed a cooperative research effort to determine the gas in place, rank, quality, extent and thickness of the Olmos coal in order to understand the resource potential of this newly emerging field.
