Toxicity tests were conducted with glochidia (24- to 48-h exposures) and juveniles (96-h exposures) of up to 11 mussel species in reconstituted ASTM hard water using copper, ammonia, or chlorine as a toxicant. Copper and ammonia tests also were conducted with five commonly tested species, including cladocerans (Daphnia magna and Ceriodaphnia dubia; 48-h exposures), amphipod (Hyalella azteca; 48-h exposures), rainbow trout (Oncorhynchus mykiss; 96-h exposures), and fathead minnow (Pimephales promelas; 96-h exposures). Median effective concentrations (EC50s) for commonly tested species were &gt;58 ??g Cu/L (except 15 ??g Cu/L for C. dubia) and &gt;13 mg total ammonia N/L, whereas the EC50s for mussels in most cases were 40 ??g/L and above the FAV in the WQC for chlorine. The results indicate that the early life stages of mussels generally were more sensitive to copper and ammonia than other organisms and that, including mussel toxicity data in a revision to the WQC, would lower the WQC for copper or ammonia. Furthermore, including additional mussel data in 2007 WQC for copper based on biotic ligand model would further lower the WQC. ?? 2007 SETAC.</p>","language":"English","publisher":"Wiley","doi":"10.1897/06-523R.1","issn":"07307268","usgsCitation":"Wang, N., Ingersoll, C., Hardesty, D., Ivey, C., Kunz, J., May, T., Dwyer, F., Roberts, A., Augspurger, T., Kane, C., Neves, R.J., and Barnhart, M., 2007, Acute toxicity of copper, ammonia, and chlorine to glochidia and juveniles of freshwater mussels (Unionidae): Environmental Toxicology and Chemistry, v. 26, no. 10, p. 2036-2047, https://doi.org/10.1897/06-523R.1.","productDescription":"12 p.","startPage":"2036","endPage":"2047","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":239999,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"10","noUsgsAuthors":false,"publicationDate":"2007-10-01","publicationStatus":"PW","scienceBaseUri":"5059e6dbe4b0c8380cd47696","contributors":{"authors":[{"text":"Wang, N.","contributorId":81615,"corporation":false,"usgs":true,"family":"Wang","given":"N.","email":"","affiliations":[],"preferred":false,"id":432101,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ingersoll, C.G. 0000-0003-4531-5949","orcid":"https://orcid.org/0000-0003-4531-5949","contributorId":56338,"corporation":false,"usgs":true,"family":"Ingersoll","given":"C.G.","affiliations":[],"preferred":false,"id":432099,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hardesty, D.K.","contributorId":43935,"corporation":false,"usgs":true,"family":"Hardesty","given":"D.K.","email":"","affiliations":[],"preferred":false,"id":432098,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ivey, C.D.","contributorId":33876,"corporation":false,"usgs":true,"family":"Ivey","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":432097,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Kunz, J.L.","contributorId":7872,"corporation":false,"usgs":true,"family":"Kunz","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":432094,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"May, T.W.","contributorId":75878,"corporation":false,"usgs":true,"family":"May","given":"T.W.","email":"","affiliations":[],"preferred":false,"id":432100,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Dwyer, F.J.","contributorId":107818,"corporation":false,"usgs":true,"family":"Dwyer","given":"F.J.","email":"","affiliations":[],"preferred":false,"id":432105,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Roberts, A.D.","contributorId":87757,"corporation":false,"usgs":true,"family":"Roberts","given":"A.D.","email":"","affiliations":[],"preferred":false,"id":432103,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Augspurger, T.","contributorId":81844,"corporation":false,"usgs":false,"family":"Augspurger","given":"T.","email":"","affiliations":[],"preferred":false,"id":432102,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Kane, C.M.","contributorId":20140,"corporation":false,"usgs":true,"family":"Kane","given":"C.M.","email":"","affiliations":[],"preferred":false,"id":432095,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Neves, R.

Identifying the habitat features that influence habitat selection and enhance fitness is critical for effective management. Ecological theory predicts that habitat choices should be adaptive, such that fitness is enhanced in preferred habitats. However, studies often report mismatches between habitat preferences and fitness consequences across a wide variety of taxa based on a single spatial scale and/or a single fitness component. 2. We examined whether habitat preferences of a declining shrub steppe songbird, the Brewer's sparrow Spizella breweri, were adaptive when multiple reproductive fitness components and spatial scales (landscape, territory and nest patch) were considered. 3. We found that birds settled earlier and in higher densities, together suggesting preference, in landscapes with greater shrub cover and height. Yet nest success was not higher in these landscapes; nest success was primarily determined by nest predation rates. Thus landscape preferences did not match nest predation risk. Instead, nestling mass and the number of nesting attempts per pair increased in preferred landscapes, raising the possibility that landscapes were chosen on the basis of food availability rather than safe nest sites. 4. At smaller spatial scales (territory and nest patch), birds preferred different habitat features (i.e. density of potential nest shrubs) that reduced nest predation risk and allowed greater season-long reproductive success. 5. Synthesis and applications. Habitat preferences reflect the integration of multiple environmental factors across multiple spatial scales, and individuals may have more than one option for optimizing fitness via habitat selection strategies. Assessments of habitat quality for management prescriptions should ideally include analysis of diverse fitness consequences across multiple ecologically relevant spatial scales. ?? 2007 The Authors.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2664.2007.01352.x","issn":"00218901","usgsCitation":"Chalfoun, A., and Martin, T.E., 2007, Assessments of habitat preferences and quality depend on spatial scale and metrics of fitness: Journal of Applied Ecology, v. 44, no. 5, p. 983-992, https://doi.org/10.1111/j.1365-2664.2007.01352.x.","startPage":"983","endPage":"992","numberOfPages":"10","costCenters":[],"links":[{"id":212505,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2664.2007.01352.x"},{"id":239998,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"5","noUsgsAuthors":false,"publicationDate":"2007-07-23","publicationStatus":"PW","scienceBaseUri":"5059ee89e4b0c8380cd49de0","contributors":{"authors":[{"text":"Chalfoun, A.D.","contributorId":16954,"corporation":false,"usgs":true,"family":"Chalfoun","given":"A.D.","email":"","affiliations":[],"preferred":false,"id":432093,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Martin, T.

Three of the eight species (Rana guentheri, Polypedates megacephalus, and Eleutherodactylus planirostris) had well-established breeding populations by 2005. A further three (Fejevarya cf. livinocharis, Fejervarya cancrivora, and Microhyla pulchra) were recorded from a number of individuals, but it is not known whether these species have established breeding populations. Two species (Kaloula pulchra and Eleutherodactylus coqui) appear to be incidental transportations to the island that have not established. Before 2003, five anuran species, all introductions, had been recorded from Guam. Three of these, Polypedates leucomystax, Pseudacris regilla, and Kaloula picta, were detected on Guam in incoming cargo but destroyed. Two species established: Bufo marinus was deliberately introduced and the Australian hylid Litoria fallax was probably an accidental introduction. Successful establishment of anurans on Guam has increased the risk of frog introductions to nearby islands. By providing additional food sources for the brown tree snake (Boiga irregularis), anuran introductions have increased the chance that B. irregularis might substantially increase in numbers and in turn increase the risk of the snake being accidentally transported to other islands. ?? 2007 by University of Hawai'i Press All rights reserved.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pacific Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2984/1534-6188(2007)61[469:RROAAO]2.0.CO;2","issn":"00308870","usgsCitation":"Christy, M., Clark, C., Gee, D., Vice, D., Vice, D., Warner, M., Tyrrell, C., Rodda, G., and Savidge, J.A., 2007, Recent records of alien anurans on the Pacific Island of Guam: Pacific Science, v. 61, no. 4, p. 469-483, https://doi.org/10.2984/1534-6188(2007)61[469:RROAAO]2.0.CO;2.","startPage":"469","endPage":"483","numberOfPages":"15","costCenters":[],"links":[{"id":477094,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/10125/22630","text":"External Repository"},{"id":212478,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2984/1534-6188(2007)61[469:RROAAO]2.0.CO;2"},{"id":239968,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9635e4b0c8380cd81e7e","contributors":{"authors":[{"text":"Christy, M.T.","contributorId":20968,"corporation":false,"usgs":true,"family":"Christy","given":"M.T.","email":"","affiliations":[],"preferred":false,"id":432084,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Clark, C.S.","contributorId":20288,"corporation":false,"usgs":true,"family":"Clark","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":432083,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gee, D.E.

Several sets of stereo image pairs were collected during the descent. The digital terrain models constructed from those images show rugged topography, in places approaching the angle of repose, adjacent to flatter darker plains. Brighter regions north of the landing site display two styles of drainage patterns: (1) bright highlands with rough topography and deeply incised branching dendritic drainage networks (up to fourth order) with dark-floored valleys that are suggestive of erosion by methane rainfall and (2) short, stubby low-order drainages that follow linear fault patterns forming canyon-like features suggestive of methane spring-sapping. The topographic data show that the bright highland terrains are extremely rugged; slopes of order of 30° appear common. These systems drain into adjacent relatively flat, dark lowland terrains. A stereo model for part of the dark plains region to the east of the landing site suggests surface scour across this plain flowing from west to east leaving ∼100-m-high bright ridges. Tectonic patterns are evident in (1) controlling the rectilinear, low-order, stubby drainages and (2) the “coastline” at the highland–lowland boundary with numerous straight and angular margins. In addition to flow from the highlands drainages, the lowland area shows evidence for more prolific flow parallel to the highland–lowland boundary leaving bright outliers resembling terrestrial sandbars. This implies major west to east floods across the plains where the probe landed with flow parallel to the highland–lowland boundary; the primary source of these flows is evidently not the dendritic channels in the bright highlands to the north.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Planetary and Space Science","largerWorkSubtype":{"id":10,"text":"Journal

Evaluating the hazards associated with such alteration is difficult because alteration has been mapped on few active volcanoes and the distribution and intensity of subsurface alteration are largely unknown on any active volcano. At Mount Adams, some Holocene debris flows contain abundant hydrothermal minerals derived from collapse of the altered edifice. Intense hydrothermal alteration significantly reduces the resistivity and magnetization of volcanic rock, and therefore hydrothermally altered rocks can be identified with helicopter electromagnetic and magnetic measurements. Electromagnetic and magnetic data, combined with geological mapping and rock property measurements, indicate the presence of appreciable thicknesses of hydrothermally altered rock in the central core of Mount Adams north of the summit. We identify steep cliffs at the western edge of this zone as the likely source for future large debris flows. In addition, the electromagnetic data identified water in the brecciated core of the upper 100–200 m of the volcano. Water helps alter the rocks, reduces the effective stress, thereby increasing the potential for slope failure, and acts, with entrained melting ice, as a lubricant to transform debris avalanches into lahars. Therefore knowing the distribution of water is also important for hazard assessments. Our results demonstrate that high-resolution geophysical and geological observations can yield unprecedented views of the three-dimensional distribution of altered rock and shallow pore water aiding evaluation of the debris avalanche hazard.</p></div></div>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2006JB004783","issn":"01480227","usgsCitation":"Finn, C., Deszcz-Pan, M., Anderson, E., and John, D., 2007, Three-dimensional geophysical mapping of rock alteration and water content at Mount Adams, Washington: Implications for lahar hazards: Journal of Geophysical Research B: Solid Earth, v. 112, no. 10, 21 p., https://doi.org/10.1029/2006JB004783.","productDescription":"21 p.","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":477084,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2006jb004783","text":"Publisher Index Page"},{"id":239763,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"112","issue":"10","noUsgsAuthors":false,"publicationDate":"2007-10-18","publicationStatus":"PW","scienceBaseUri":"505bb32be4b08c986b325c16","contributors":{"authors":[{"text":"Finn, C.

Growth rates of Mooneye differed between the Tallapoosa River population and a previously studied population from the northern extent of the species' range (Assiniboine River, MB, Canada). In addition, fecundity of Mooneye from the Tallapoosa River was similar to the northern population, ranging from 5321 to 7432 eggs per female. Because the species is declining throughout its range in Alabama, we recommend that managers use our findings in conservation efforts. Future studies should investigate how hydrology influences the spawning success and early growth and development of Mooneye in regulated systems.

The survival of subyearling Chinook salmon Oncorhynchus tshawytscha released into the system ranged from 0.774 to 0.911 and was significantly lower than the survival of test fish released into turbines and the area immediately below the powerhouse where bypass system flow reentered the river. Yearling and subyearling Chinook salmon and yearling coho salmon O. kisutch released into the bypass system were injured or descaled. Also, levels of blood plasma cortisol and lactate were significantly higher in yearling and subyearling Chinook salmon that passed through the bypass system than in fish released directly into a net located over the bypass exit. This original system was then extensively modified using updated design criteria, and the site where juvenile fish reentered the river was relocated 2.8 km further downstream to reduce predation on bypassed fish by northern pikeminnow Ptychocheilus oregonensis. Based on studies conducted from 1999 to 2001, the new bypass system resulted in high fish survival, virtually no injuries to fish, fish passage times that were generally similar to water travel times, and mild stress responses from which fish recovered quickly. The mean estimated survival of subyearling Chinook salmon passing through the new bypass system was 0.946 in 2001, which was an usually low-flow year. Survival, physical condition, passage timing, and blood physiological indicators of stress were all useful metrics for assessing the performance of both bypass systems and are discussed. The engineering and hydraulic criteria used to design the new bypass system that resulted in improved fish passage conditions are described.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/T06-158.1","issn":"00028487","usgsCitation":"Ferguson, J., Sandford, B., Reagan, R., Gilbreath, L., Meyer, E., Ledgerwood, R., and Adams, N., 2007, Bypass system modification at Bonneville Dam on the Columbia River improved the survival of juvenile salmon: Transactions of the American Fisheries Society, v. 136, no. 6, p. 1487-1510, https://doi.org/10.1577/T06-158.1.","startPage":"1487","endPage":"1510","numberOfPages":"24","costCenters":[],"links":[{"id":212241,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/T06-158.1"},{"id":239699,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"136","issue":"6","noUsgsAuthors":false,"publicationDate":"2011-01-09","publicationStatus":"PW","scienceBaseUri":"5059f2bfe4b0c8380cd4b338","contributors":{"authors":[{"text":"Ferguson, J.W.","contributorId":87755,"corporation":false,"usgs":true,"family":"Ferguson","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":432015,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sandford, B.P.","contributorId":27234,"corporation":false,"usgs":true,"family":"Sandford","given":"B.P.","email":"","affiliations":[],"preferred":false,"id":432012,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reagan, R.E.","contributorId":50474,"corporation":false,"usgs":true,"family":"Reagan","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":432013,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gilbreath, L.G.","contributorId":21762,"corporation":false,"usgs":true,"family":"Gilbreath","given":"L.G.","email":"","affiliations":[],"preferred":false,"id":432011,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Meyer, E.B.","contributorId":19779,"corporation":false,"usgs":true,"family":"Meyer","given":"E.B.","email":"","affiliations":[],"preferred":false,"id":432010,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ledgerwood, R.D.","contributorId":73820,"corporation":false,"usgs":true,"family":"Ledgerwood","given":"R.D.","email":"","affiliations":[],"preferred":false,"id":432014,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Adams, N.S.","contributorId":93175,"corporation":false,"usgs":true,"family":"Adams","given":"N.S.","affiliations":[],"preferred":false,"id":432016,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

However, empirical evidence for food-related stress in wild animals is frequently lacking or inconclusive. We used a field endocrinology approach to measure stress, identify its causes, and examine a link between stress and population processes in the common murre Uria aalge. We tested the empirical relationship between variations in the stress hormone corticosterone (CORT) and food abundance, reproduction, and persistence of individuals at declining and increasing colonies in Cook Inlet, Alaska, from 1996 to 2001. We found that CORT secretion in murres is independent of colony, reproductive stage effects, and gender of individuals, but is directly negatively correlated with abundance of their food. Baseline CORT reflected current food abundance, whereas acute stress-induced CORT reflected food abundance in the previous month. As food supply diminished, increased CORT secretion predicted a decrease in reproductive performance. At a declining colony, increased baseline levels of CORT during reproduction predicted disappearance of individuals from the population. Persistence of individuals in a growing colony was independent of CORT during reproduction. The obtained results support the hypothesis that nutritional stress during reproduction affects reproduction and survival in seabirds. This study provides the first unequivocal evidence for CORT secretion as a mechanistic link between fluctuations in food abundance and population processes in seabirds. ??

Evidence for these previously undescribed spring deposits includes calcite macroscopic structures within the quarry strata - such as pisolites and travertine fragments - and calcite micromorphologies - including radial-fibrous, feather, and scandulitic dendrite morphologies and tufa clasts. At least two episodes of bone incorporation are preserved in the quarry based on their stratigraphic position and lithologic associations. The unique depositional setting in and around the Crystal Geyser Dinosaur Quarry appears to have been favorable for the preservation of vertebrate fossils and provides insight into early Cretaceous environments in North America.

Individuals from 2 of these lineages, an eastern and a western form, co-occur within maternity colonies in Colorado. The discovery of 2 divergent mtDNA lineages in sympatry prompted a set of questions regarding possible biological differences between haplotypes. We captured big brown bats at maternity roosts in Colorado and recorded data on body size, pelage color, litter size, roosting and overwintering behaviors, and local distributions. Wing biopsies were collected for genetic analysis. The ND2 region of the mtDNA molecule was used to determine lineage of the bats. In addition, nuclear DNA (nDNA) intron 1 of the ??-globin gene was used to determine if mtDNA lineages are hybridizing. Eastern and western mtDNA lineages differed by 10.3% sequence divergence and examination of genetic data suggests recent population expansion for both lineages. Differences in distribution occur along the Colorado Front Range, with an increasing proportion of western haplotypes farther south. Results from nDNA analyses demonstrated hybridization between the 2 lineages. Additionally, no outstanding distinctiveness was found between the mtDNA lineages in natural history characters examined. We speculate that historical climate changes separated this species into isolated eastern and western populations, and that secondary contact with subsequent interbreeding was facilitated by European settlement. ?? 2007 American Society of Mammalogists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1644/06-MAMM-A-228R1.1","issn":"00222372","usgsCitation":"Neubaum, M., Douglas, M., Douglas, M., and O'Shea, T., 2007, Molecular ecology of the big brown bat (Eptesicus fuscus): Genetic and natural history variation in a hybrid zone: Journal of Mammalogy, v. 88, no. 5, p. 1230-1238, https://doi.org/10.1644/06-MAMM-A-228R1.1.","startPage":"1230","endPage":"1238","numberOfPages":"9","costCenters":[],"links":[{"id":212567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/06-MAMM-A-228R1.1"},{"id":240070,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"88","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5d01e4b0c8380cd700cb","contributors":{"authors":[{"text":"Neubaum, M.A.","contributorId":50866,"corporation":false,"usgs":true,"family":"Neubaum","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":431968,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Douglas, M.R.","contributorId":76548,"corporation":false,"usgs":true,"family":"Douglas","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":431969,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Douglas, M.E.","contributorId":43570,"corporation":false,"usgs":true,"family":"Douglas","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":431966,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"O'Shea, T.

After adjustments to a few parameters (specifically the SURLAG variable, the runoff curve number, Manning's N for overland flow, soil available water capacity, and the base-flow alpha factor) the SWAT model fit the observed streamflow well (the Coefficient of Efficiency and R2 were greater than 60). The results from comparing observed fluometuron concentrations with simulated concentrations were reasonable. The simulated concentrations (which were daily averages) followed the pattern of observed concentrations (instantaneous values) closely, but could be off in magnitude at times.

Celastrus orbiculatus (oriental bittersweet) is a liana introduced into the United States in the mid-1800s from East Asia as an ornamental plant. Its native congener, Celastrus scandens (American bittersweet), ranges from the east coast of the United States as far west as Wyoming. In the Northeastern United States, C. orbiculatus is continuing to expand its range while C. scandens appears to be in serious decline. One hypothesis for this decline is that C. scandens does not have such a wide range of ecological tolerances in the current landscape as C. orbiculatus, which seems to tolerate a greater range of resource conditions. To investigate this hypothesis, we transplanted these two species into ten sites that spanned a full range of light and soil moisture conditions to compare their establishment and performance in terms of aboveground growth (biomass and height) and mortality. After two years, C. orbiculatus showed significantly lower mortality and greater biomass across all resource conditions compared to C. scandens. In addition, C. orbiculatus preferred more mesic soil moisture conditions, while C. scandens performed better in drier soil moisture conditions. Since much of the Northeastern United States is now forested, this preference for mesic soil conditions could make it more successful than C. scandens in the region. This study shows the utility of manipulative experiments, particularly those using congeneric native species as benchmarks, for assessing the causes and predicting the course of invasions. ?? 2007 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Oecologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00442-007-0839-3","issn":"00298549","usgsCitation":"Leicht-Young, S.A., Silander, J., and Latimer, A., 2007, Comparative performance of invasive and native Celastrus species across environmental gradients: Oecologia, v. 154, no. 2, p. 273-282, https://doi.org/10.1007/s00442-007-0839-3.","startPage":"273","endPage":"282","numberOfPages":"10","costCenters":[],"links":[{"id":212504,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00442-007-0839-3"},{"id":239997,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"154","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-08-28","publicationStatus":"PW","scienceBaseUri":"5059f821e4b0c8380cd4ced0","contributors":{"authors":[{"text":"Leicht-Young, S.

Typical treatment of mine drainage waters involves pH adjustment, but this often results in excessive sludge formation and removal of nontoxic species such as magnesium and calcium. Theoretical consideration of the stability of metal carbonate species suggests that the target metals could be removed from solution by coprecipitation with calcium carbonate. The U.S. Geological Survey has developed a limestone-based process for remediation of acid mine drainage that increases calcium carbonate saturation. This treatment could then be coupled with carbonate coprecipitation as an innovative method for removal of toxic metals from circumneutral mine drainage waters. The new process was termed the carbonate coprecipitation (CCP) process. The CCP process was tested at the laboratory scale using a synthetic mine water containing 50 mg/L each of Mn and Zn. Best results showed over 95% removal of both Mn and Zn in less than 2 h of contact in a limestone channel. The process was then tested on a sample of water from the Palmerton zinc superfund site, near Palmerton, Pennsylvania, containing over 300 mg/L Zn and 60 mg/L Mn. Treatment of this water resulted in removal of over 95% of the Zn and 40% of the Mn in the limestone channel configuration. Because of the potential economic advantages of the CCP process, further research is recommended for refinement of the process for the Palmerton water and for application to other mining impacted waters as well. ??

The production of evaporite minerals during evaporative loss of near-surface ground water results in both the creation and maintenance of several centimeters or more of loose sediment on and near the surfaces of wet playas. Observations that characterize the texture, mineralogic composition and hardness of playa surfaces at Franklin Lake, Soda Lake and West Cronese Lake playas in the Mojave Desert (California), along with imaging of dust emission using automated digital photography, indicate that these kinds of surface sediment are highly susceptible to dust emission. The surfaces of wet playas are dynamic - surface texture and sediment availability to wind erosion change rapidly, primarily in response to fluctuations in water-table depth, rainfall and rates of evaporation. In contrast, dry playas are characterized by ground water at depth. Consequently, dry playas commonly have hard surfaces that produce little or no dust if undisturbed except for transient silt and clay deposited on surfaces by wind and water. Although not the dominant type of global dust, salt-rich dusts from wet playas may be important with respect to radiative properties of dust plumes, atmospheric chemistry, windborne nutrients and human health.","language":"English","publisher":"Wiley","doi":"10.1002/esp.1515","issn":"01979337","usgsCitation":"Reynolds, R.L., Yount, J., Reheis, M.C., Goldstein, H.L., Chavez, P.F., Fulton, R.E., Whitney, J.W., Fuller, C.C., and Forester, R.M., 2007, Dust emission from wet and dry playas in the Mojave Desert, USA: Earth Surface Processes and Landforms, v. 32, no. 12, p. 1811-1827, https://doi.org/10.1002/esp.1515.","productDescription":"17 p.","startPage":"1811","endPage":"1827","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":239862,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Mojave Desert","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -119,\n              34\n            ],\n            [\n              -113,\n              34\n            ],\n            [\n              -113,\n              37\n            ],\n            [\n              -119,\n              37\n            ],\n            [\n              -119,\n              34\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"32","issue":"12","noUsgsAuthors":false,"publicationDate":"2007-04-19","publicationStatus":"PW","scienceBaseUri":"505a041de4b0c8380cd507c1","contributors":{"authors":[{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":441,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":271,"text":"Federal Center","active":false,"usgs":true}],"preferred":true,"id":431895,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yount, James C.","contributorId":39341,"corporation":false,"usgs":true,"family":"Yount","given":"James C.","affiliations":[],"preferred":false,"id":431893,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reheis, Marith C. 0000-0002-8359-323X mreheis@usgs.gov","orcid":"https://orcid.org/0000-0002-8359-323X","contributorId":138571,"corporation":false,"usgs":true,"family":"Reheis","given":"Marith","email":"mreheis@usgs.gov","middleInitial":"C.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":431890,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Goldstein, Harland L. 0000-0002-6092-8818 hgoldstein@usgs.gov","orcid":"https://orcid.org/0000-0002-6092-8818","contributorId":147881,"corporation":false,"usgs":true,"family":"Goldstein","given":"Harland","email":"hgoldstein@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":false,"id":431896,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Chavez, Pat F.

The clay bed is composed of pure nontronite (described for the first time in the Tyrrhenian Sea), which appears to be the most aluminous nontronite ever found among the seafloor hydrothermal deposits. The high Al content suggests precipitation from Al-containing hydrothermal solutions. The REE distribution of the Eolo nontronite has a V-shape pattern. The heavy REE enrichment is in part due to their preferential partitioning in the nontronite structure. This enrichment was possibly further enhanced by the HREE preferential sorption on bacterial cell walls. The light REE enrichment is the result of scavenging uptake by one of the nontronite precursors, i.e., poorly-ordered Fe-oxyhydroxides, from the hydrothermal fluids. Oxygen isotopic composition of the nontronite yields a formation temperature of 30????C, consistent with a low-temperature hydrothermal origin. The relatively radiogenic Nd isotopic signature of the nontronite compared to the present-day Mediterranean seawater indicates that approximately half of Nd, and presumably the rest of the LREE, are derived from local volcanic sources. On the other hand, 87Sr/86Sr is dominated by present-day seawater Sr. Scanning electron microscopy investigation revealed that the nontronite is composed of aggregates of lepispheres and tube-like filaments, which are indicative of bacteria assisted precipitation. Bacteria inhabiting this hydrothermal site likely acted as reactive geochemical surfaces on which poorly-ordered hydrothermal Fe-oxyhydroxides and silica precipitated. Upon aging, the interactions of these primary hydrothermal precipitates coating bacterial filaments and cell walls likely led to the formation of nontronite. Finally, the well-balanced interlayer and layer charges of the crystal lattice of seafloor hydrothermal nontronite decrease its sorption capacity to zero. Thus the ubiquitous nontronite precipitation along the active plate boundaries and around the hot spots has no significant impact on oceanic trace element chemistry. ?? 2007 Elsevier B.V.

Measurements of surface salinity and bacterial counts collected from research vessels were compared to MODIS-Aqua satellite imagery. The spectra of normalized water-leaving radiation (nLw) were different in plumes and ambient ocean waters, enabling plumes discrimination and plume area size assessments from remotely-sensed data. The plume/ocean nLw differences (i.e., plume optical signatures) were most evident during first days after the rainstorm over the San Pedro shelf and in the San Diego region and less evident in Santa Monica Bay, where suspended sediments concentration in discharged water was lower than in other regions. In the Ventura area, plumes contained more suspended sediments than in other regions, but the grid of ship-based stations covered only a small part of the freshwater plume and was insufficient to reveal the differences between the plume and ocean optical signatures. The accuracy of plume area assessments from satellite imagery was not high (77% on average), seemingly because of inexactitude in satellite data processing. Nevertheless, satellite imagery is a useful tool for the estimation of the extent of polluted plumes, which is hardly achievable by contact methods.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of SPIE - The International Society for Optical Engineering","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"Coastal Ocean Remote Sensing","conferenceDate":"August 26-27, 2007","conferenceLocation":"San Diego, CA","language":"English","publisher":"SPIE","doi":"10.1117/12.732754","issn":"0277786X","isbn":"9780819468284","usgsCitation":"Nezlin, N., DiGiacomo, P., Jones, B., Reifel, K., Warrick, J., Johnson, S., and Mengel, M., 2007, MODIS imagery as a tool for synoptic water quality assessments in the southern California coastal ocean, <i>in</i> Proceedings of SPIE - The International Society for Optical Engineering, v. 6680, San Diego, CA, August 26-27, 2007, https://doi.org/10.1117/12.732754.","costCenters":[],"links":[{"id":239794,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6680","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4ae6e4b0c8380cd69127","contributors":{"authors":[{"text":"Nezlin, N.P.","contributorId":77644,"corporation":false,"usgs":true,"family":"Nezlin","given":"N.P.","affiliations":[],"preferred":false,"id":431873,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DiGiacomo, P.M.","contributorId":39501,"corporation":false,"usgs":true,"family":"DiGiacomo","given":"P.M.","affiliations":[],"preferred":false,"id":431870,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jones, B.H.","contributorId":96810,"corporation":false,"usgs":true,"family":"Jones","given":"B.H.","email":"","affiliations":[],"preferred":false,"id":431875,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Reifel, K.M.","contributorId":49327,"corporation":false,"usgs":true,"family":"Reifel","given":"K.M.","affiliations":[],"preferred":false,"id":431871,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Warrick, J.A.","contributorId":53503,"corporation":false,"usgs":true,"family":"Warrick","given":"J.A.","affiliations":[],"preferred":false,"id":431872,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Johnson, S.C.","contributorId":93008,"corporation":false,"usgs":true,"family":"Johnson","given":"S.C.","email":"","affiliations":[],"preferred":false,"id":431874,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mengel, M.J.","contributorId":21267,"corporation":false,"usgs":true,"family":"Mengel","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":431869,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

To further assess the validity of the recovery units, we analyzed genetic data by using mitochondrial deoxyribonucleic acid (mtDNA) sequences and nuclear DNA microsatellites. In total, 125 desert tortoises were sampled for mtDNA and 628 for microsatellites from 31 study sites, representing all recovery units and desert regions throughout the Mojave Desert in California and Utah, and the Colorado Desert of California. The mtDNA revealed a great divergence between the Mojave populations west of the Colorado River and those occurring east of the river in the Sonoran Desert of Arizona. Some divergence also occurred between northern and southern populations within the Mojave population. The microsatellites indicated a low frequency of private alleles and a significant correlation between genetic and geographic distance among 31 sample sites, which was consistent with an isolation-by-distance population structure. Regional genetic differentiation was complementary to the recovery units in the Recovery Plan. Most allelic frequencies in the recovery units differed. An assignment test correctly placed most individuals to their recovery unit of origin. Of the 6 recovery units, the Northeastern and the Upper Virgin River units showed the greatest differentiation; these units may have been relatively more isolated than other areas and should be managed accordingly. The Western Mojave Recovery Unit, by using the new genetic data, was redefined along regional boundaries into the Western Mojave, Central Mojave, and Southern Mojave recovery units. Large-scale translocations of tortoises and habitat disturbance throughout the 20th century may have contributed to the observed patterns of regional similarity. ?? 2007 Chelonian Research Foundation.","language":"English","publisher":"BioOne","doi":"10.2744/1071-8443(2007)6[229:AGAOTR]2.0.CO;2","issn":"10718443","usgsCitation":"Murphy, R., Berry, K., Edwards, T., and McLuckie, A., 2007, A genetic assessment of the recovery units for the mojave population of the desert tortoise, Gopherus agassizii: Chelonian Conservation and Biology, v. 6, no. 2, p. 229-251, https://doi.org/10.2744/1071-8443(2007)6[229:AGAOTR]2.0.CO;2.","productDescription":"23 p.","startPage":"229","endPage":"251","numberOfPages":"23","costCenters":[],"links":[{"id":495013,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.2744/1071-8443(2007)6[229:agaotr]2.0.co;2","text":"Publisher Index Page"},{"id":239328,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Mojave Desert","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.82887195343143,\n              36.14319621654907\n            ],\n            [\n              -116.82887195343143,\n              33.116789670872976\n            ],\n            [\n              -114.01757814690296,\n              33.116789670872976\n            ],\n            [\n              -114.01757814690296,\n              36.14319621654907\n            ],\n            [\n              -116.82887195343143,\n              36.14319621654907\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"6","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e3f1e4b0c8380cd462f1","contributors":{"authors":[{"text":"Murphy, R.

Theoretical and empirical studies suggest that parental care behaviors can evolve in response to nest predation risk and thereby differ among ecological conditions that vary in inherent risk. However, parental care also can influence predation risk. Separating the effects of nest predation risk inherent to a nest site from the risk imposed by parental strategies is needed to understand the evolution of parental care. Here we identify correlations between risks inherent to nest sites, and risk associated with parental care behaviors, and use an artificial nest experiment to assess site-specific differences in nest predation risk across nesting guilds and between habitats that differed in nest predator abundance. We found a strong correlation between parental care behaviors and inherent differences in nest predation risk, but despite the absence of parental care at artificial nests, patterns of nest predation risk were similar for real and artificial nests both across nesting guilds and between predator treatments. Thus, we show for the first time that inherent risk of nest predation varies with nesting guild and predator abundance independent of parental care. ??

Estuaries within a class have similar physical and hydrologic characteristics and would be expected to demonstrate similar biological responses to stressor loads from the adjacent watersheds. Nine classes of estuaries were identified by applying cluster analysis to a database for 138 U.S. estuarine drainage areas. The database included physical measures of estuarine areas, depth and volume, as well as hydrologic parameters (i.e., tide height, tidal prism volume, freshwater inflow rates, salinity, and temperature). The ability of an estuary to dilute or flush pollutants can be estimated using physical and hydrologic properties such as volume, bathymetry, freshwater inflow and tidal exchange rates which influence residence time and affect pollutant loading rates. Thus, physical and hydrologic characteristics can be used to estimate the susceptibility of estuaries to pollutant effects. This classification of estuaries can be used by natural resource managers to describe and inventory coastal systems, understand stressor impacts, predict which systems are most sensitive to stressors, and manage and protect coastal resources. ??
