Along-axis flow within the lower crust could be induced by the reduction of overburden pressure in the central Dead Sea basin, where brittle extensional deformation is observed. Using a channel flow approximation, we estimate that lower crustal flow would occur within the time frame of basin subsidence if the viscosity is ≤7×1019–1×1021 Pa s, a value compatible with the normal heat flow in the region. Lower crustal viscosity due to the strain rate associated with basin extension is estimated to be similar to or smaller than the viscosity required for a channel flow. However, the viscosity under the basin may be reduced to 5×1017–5×1019 Pa s by the enhanced strain rate due to lateral shear along the transform plate boundary. Thus, lower crustal flow facilitated by shear may be a viable mechanism to enlarge basins and modify other topographic features even in the absence of underlying thermal anomalies.

However, most attempts to document the effects of enrichment on animal behavior have focused on terrestrial mammals. Staff at the National Aquarium in Baltimore conducted an investigation of the behavioral effects of enrichment on the seven harbor seals and two gray seals housed in the aquarium's outdoor seal exhibit. We expected that enrichment would change the amount of time the animals spent engaged in specific behaviors. The behaviors recorded were: resting in water, resting hauled out, maintenance, breeding display, breeding behavior, aggression, pattern swimming, random swimming, exploration, and out of sight. Activity levels (random swimming and exploration) were expected to increase, while stereotypic behaviors (pattern swimming) were expected to decrease. The frequency and duration of behaviors were documented for 90 hr in both the control phase (without enrichment) and the experimental phase (with enrichment). Statistically significant differences (P < 0.05) in the time spent in pattern swimming, random swimming, exploration, and out of sight were observed between the two phases. With enrichment, pattern swimming and out of sight decreased, while random swimming and exploration behavior increased. These findings demonstrate that enrichment can promote behaviors (random swimming and exploration) that are likely to be normal for phocids in the wild, and that may contribute to the behavioral complexity of these seals in captivity. ?? 2002 Wiley-Liss, Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Zoo Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/zoo.10042","issn":"07333188","usgsCitation":"Hunter, S., Bay, M.S., Martin, M.L., and Hatfield, J., 2002, Behavioral effects of environmental enrichment on harbor seals (Phoca vitulina concolor) and gray seals (Halichoerus grypus): Zoo Biology, v. 21, no. 4, p. 375-387, https://doi.org/10.1002/zoo.10042.","startPage":"375","endPage":"387","numberOfPages":"13","costCenters":[],"links":[{"id":231823,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207146,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/zoo.10042"}],"volume":"21","issue":"4","noUsgsAuthors":false,"publicationDate":"2002-07-10","publicationStatus":"PW","scienceBaseUri":"5059f0a6e4b0c8380cd4a828","contributors":{"authors":[{"text":"Hunter, S.

The landslide was approximately 980 m long, 870 m wide, and encompassed an area of approximately 68 ha. Drilling data suggested that movement may have extended to depths as great as 85 m below the ground surface. Even though the landslide moved <1 m, it caused substantial damage to numerous dwellings and other structures, primarily as a result of differential displacements and internal Assuring. Surface cracks, scarps, and compression features delineating the Villa Del Monte landslide were discontinuous, probably because coseismic displacements were small; such discontinuous features were also characteristic of the other large, coseismic landslides in the area, which also moved only short distances during the earthquake. Because features marking landslide boundaries were discontinuous and because other types of coseismic ground cracks were widespread in the area, identification of the landslides required detailed mapping and analysis. Recognition that landslides such as that at Villa Del Monte may occur near earthquake-generating fault ruptures should aid in future hazard evaluations of areas along active faults.

A hybrid, low-frequency, high-frequency method is used to calculate broadband (0-20 Hz) ground-motion time histories for a M 6.5 earthquake on the Seattle fault. Low frequencies (1 Hz) are calculated by a stochastic method that uses a fractal subevent size distribution to give an ω-2 displacement spectrum. Time histories are calculated for a grid of stations and then corrected for the local site response using a classification scheme based on the surficial geology. Average shear-wave velocity profiles are developed for six surficial geologic units: artificial fill, modified land, Esperance sand, Lawton clay, till, and Tertiary sandstone. These profiles together with other soil parameters are used to compare linear, equivalent-linear, and nonlinear predictions of ground motion in the frequency band 0-15 Hz. Linear site-response corrections are found to yield unreasonably large ground motions. Equivalent-linear and nonlinear calculations give peak values similar to the 1994 Northridge, California, earthquake and those predicted by regression relationships. Ground-motion variance is estimated for (1) randomization of the velocity profiles, (2) variation in source parameters, and (3) choice of nonlinear model. Within the limits of the models tested, the results are found to be most sensitive to the nonlinear model and soil parameters, notably the over consolidation ratio.

We immobilized captive swift foxes to determine the safety and effectiveness of ketamine hydrochloride and xylazine hydrochloride at different dosages. We attempted to determine appropriate dosages to immobilize swift foxes for an adequate field-handling period based on three anesthesia intervals (induction period, immobilization period, and recovery period) and physiologic responses (rectal temperature, respiration rate, and heart rate). Between October 1998–July 1999, we conducted four trials, evaluating three different dosage ratios of ketamine and xylazine (2.27:1.2, 5.68:1.2, and 11.4:1.2 mg/kg ketamine:mg/kg xylazine, respectively), followed by a fourth trial with a higher dosage at the median ratio (11.4 mg/kg ketamine:2.4 mg/kg xylazine). We found little difference in induction and recovery periods among trials 1–3, but immobilization time increased with increasing dosage (P<0.08). Both the immobilization period and recovery period increased in trial 4 compared with trials 1–3 (P≤0.03). There was a high variation in responses of individual foxes across trials, making it difficult to identify an appropriate dosage for field handling. Heart rate and respiration rates were depressed but all physiologic measures remained within normal parameters established for domestic canids. We recommend a dosage ratio of 10 mg/kg ketamine to 1 mg/kg xylazine to immobilize swift foxes for field handling.

Glochidia of C. stegaria are contained in red, worm-like conglutinates that resemble oligochaetes. Conglutinates are 20 to 80 mm long and are released through the excurrent aperture. Estimated fecundity was 22,357 to 63,459 glochidia/mussel. Eighty-four valves of C. stegaria were thin-sectioned for aging; ages ranged from 6 to 26 y. Of 16 fish species tested, 9 hosts were identified through induced infestations of glochidia: mottled sculpin (Cottus bairdi), banded sculpin (Cottus carolinae), greenside darter (Etheostoma blennioides), snubnose darter (Etheostoma simoterum), banded darter (Etheostoma zonale), tangerine darter (Percina aurantiaca), blotchside logperch (Percina burtoni), logperch (Percina caprodes), and Roanoke darter (Percina roanoka). Newly metamorphosed juveniles were cultured in recirculating and nonrecirculating aquaculture systems within dishes containing sediments of 300 to 500 μm diameter (sand) or <105 μm diameter (silt), and fed either the green algae Neochloris oleoabundans or Scenedesmus quadricauda daily. Growth and survival of juvenile mussels were highest in the nonrecirculating aquaculture system, with a mean survival of 72% after 2 wk and 38% after 4 wk.

The sandstones in these formations have very low permeability, so low that successful production of gas requires the presence of fractures. To increase gas production, the natural fracture system of these \"tight gas sandstones\" must be augmented by inducing artificial fractures, while minimizing the amount of formation damage due to introduced fluids. The Multiwell Experiment was undertaken to provide geological characterization, obtain physical property data, and perform stimulation experiments in the Iles and Williams Fork Formations. Three vertical wells and one follow-up slant well were drilled, logged, partially cored, tested for gas production, stimulated in various manners, and tested again. Drawing from published reports and papers, this review paper presents well log, core, and test data from the Multiwell Experiment while emphasizing the geological controls on gas production at the site. Gas production is controlled primarily by a set of regional fractures trending west-northwest. The fractures are vertical, terminating at lithologic boundaries within and at the upper and lower boundaries of sandstone beds. Fractures formed preferentially in sandstones where in situ stress and fracture gradients are lower than in shales and mudstones. The fractures cannot be identified adequately in vertical wellbores; horizontal wells are required. Because present-day maximum horizontal stress is aligned with the regional fractures, artificial fractures induced by pressuring the wellbore form parallel to the regional fractures rather than linking them, with consequent limitations upon enhancement of gas production.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mountain Geologist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"0027254X","usgsCitation":"Nelson, P.H., 2002, A review of the multiwell experiment in tight gas sandstones of the Mesaverde Group, Piceance Basin, Colorado: Mountain Geologist, v. 39, no. 3, p. 53-71.","startPage":"53","endPage":"71","numberOfPages":"19","costCenters":[],"links":[{"id":235840,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"39","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e55ee4b0c8380cd46cf6","contributors":{"authors":[{"text":"Nelson, P.

Between 1998 and 2001, wing clipped sentinel birds (wild American coots and game farm mallards [Anas platyrhynchos]) were released at Lake Surf, North Carolina, a lake with recurrent outbreaks of AVM, in order to gain a better understanding of the epizootiology of the disease. As early as 5-7 days post-release, sentinel coots and mallards showed neurologic signs of disease and were confirmed with AVM upon histologic examination of their brains. Serial releases of sentinel mallards during the summer, fall, and winter of 2000-01 demonstrated that exposure to the causative agent at a threshold sufficient to manifest disease was seasonal and occurred over about a 2 mo period, during November and December. Our findings that disease onset can be very rapid (5-7 days) and that exposure to the causative agent of AVM is site-specific, seasonal (late fall to early winter), and occurs over a relatively short duration (several months) supports the hypothesis that the disease is caused by a chemical substance, most likely of natural origin.

Effects of land processes on variability of monthly river discharge","docAbstract":"A salient characteristic of river discharge is its temporal variability. The time series of flow at a point on a river can be viewed as the superposition of a smooth seasonal cycle and an irregular, random variation. Viewing the random component in the spectral domain facilitates both its characterization and an interpretation of its major physical controls from a global perspective. The power spectral density functions of monthly flow anomalies of many large rivers worldwide are typified by a “red noise” process: the density is higher at low frequencies (e.g., <1 y−1) than at high frequencies, indicating disproportionate (relative to uncorrelated “white noise”) contribution of low frequencies to variability of monthly flow. For many high‐latitude and arid‐region rivers, however, the power is relatively evenly distributed across the frequency spectrum. The power spectrum of monthly flow can be interpreted as the product of the power spectrum of monthly basin total precipitation (which is typically white or slightly red) and several filters that have physical significance. The filters are associated with (1) the conversion of total precipitation (sum of rainfall and snowfall) to effective rainfall (liquid flux to the ground surface from above), (2) the conversion of effective rainfall to soil water excess (runoff), and (3) the conversion of soil water excess to river discharge. Inferences about the roles of each filter can be made through an analysis of observations, complemented by information from a global model of the ocean‐atmosphere‐land system. The first filter causes a snowmelt‐related amplification of high‐frequency variability in those basins that receive substantial snowfall. The second filter causes a relatively constant reduction in variability across all frequencies and can be predicted well by means of a semiempirical water balance relation. The third filter, associated with groundwater and surface water storage in the river basin, causes a strong reduction in high‐frequency variability of many basins. The strength of this reduction can be quantified by an average residence time of water in storage, which is typically on the order of 20–50 days. The residence time is demonstrably influenced by freezing conditions in the basin, fractional cover of the basin by lakes, and runoff ratio (ratio of mean runoff to mean precipitation). Large lake areas enhance storage and can greatly increase total residence times (100 to several hundred days). Freezing conditions appear to cause bypassing of subsurface storage, thus reducing residence times (0–30 days). Small runoff ratios tend to be associated with arid regions, where the water table is deep, and consequently, most of the runoff is produced by processes that bypass the saturated zone, leading to relatively small residence times for such basins (0–40 days).

The largest stress-induced pore pressure changes occur when fluid is trapped in pores in an “undrained” condition. We have measured the undrained poroelastic response of two sandstones to changes in mean and deviatoric stress. Pore pressure was found to respond to mean stress σm in the usual manner: Δp = BΔσm (B ranging from 0.4 to 0.7), nearly independent of the ambient deviatoric stress state. However, variations in deviatoric stress (σd = (σ1 − σ3)/2) at constant mean stress were also found to induce a reversible (elastic) pore pressure response to stress levels up to and exceeding 80% failure stress (i.e., Δp = ![\"image\"](\"https://agupubs.onlinelibrary.wiley.com/cms/asset/5598fe28-61b6-4865-8b44-a5eea3d516bd/jgrb13299-math-0001.gif\")
= const.). The coefficient η became more negative with increasing deviatoric stress level in sandstone and Ottawa sand samples. That is, η represents a dilatant response where increased deviatoric stress causes a decrease in pore pressure. The poroelastic response to deviatoric stress is explained in terms of anisotropic matrix stiffening due to closure of crack-like pore space or flattening of grain contacts at high ambient stress levels and can be important in calculations of earthquake stress transfer.

This earthquake was located 10-15 km west of Shishaldin Volcano, a large, frequently active basaltic-andesite stratovolcano. A Strombolian eruption began at Shishaldin roughly 1 month after the mainshock, culminating in a large explosive eruption on 19 April. We address the question of whether or not the eruption caused the mainshock by computing the Coulomb stress change caused by an inflating dike on fault planes oriented parallel to the mainshock focal mechanism. We found Coulomb stress increases of ???0.1 MPa in the region of the mainshock, suggesting that magma intrusion prior to the eruption could have caused the mainshock. Satellite and seismic data indicate that magma was moving upwards beneath Shishaldin well before the mainshock. indicating that, in an overall sense, the mainshock cannot be said to have caused the eruption. However, observations of changes at the volcano following the mainshock and several large aftershocks suggest that the earthquakes may, in turn, have influenced the course of the eruption.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Volcanology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00445-002-0226-1","issn":"02588900","usgsCitation":"Moran, S., Stihler, S., and Power, J., 2002, A tectonic earthquake sequence preceding the April-May 1999 eruption of Shishaldin Volcano, Alaska: Bulletin of Volcanology, v. 64, no. 8, p. 520-524, https://doi.org/10.1007/s00445-002-0226-1.","startPage":"520","endPage":"524","numberOfPages":"5","costCenters":[],"links":[{"id":207058,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00445-002-0226-1"},{"id":231644,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"64","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e5f2e4b0c8380cd47050","contributors":{"authors":[{"text":"Moran, S.C. 0000-0001-7308-9649","orcid":"https://orcid.org/0000-0001-7308-9649","contributorId":78896,"corporation":false,"usgs":true,"family":"Moran","given":"S.C.","affiliations":[],"preferred":false,"id":400355,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stihler, S.D.","contributorId":42616,"corporation":false,"usgs":true,"family":"Stihler","given":"S.D.","email":"","affiliations":[],"preferred":false,"id":400354,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Power, J.A.","contributorId":20765,"corporation":false,"usgs":true,"family":"Power","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":400353,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Surface-water and groundwater ecosystems are viewed as linked components of a hydrologic continuum leading to related sustainability issues. This overview concludes with a discussion of research needs and challenges facting this evolving field. The biogeochemical processes within the upper few centimeters of sediments beneath nearly all surface-water bodies (hyporheic zone) have a profound effect on the chemistry of the water interchange, and here is where most of the recent research has been focusing. However, to advance conceptual and other modeling of GW-SW systems, a broader perspective of such interactions across and between surface-water bodies is needed, including multidimensional analyses, interface hydraulic characterization and spatial variability, site-to-region regionalization approaches, as well as cross-disciplinary collaborations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrogeology Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10040-001-0170-8","issn":"14312174","usgsCitation":"Sophocleous, M., 2002, Interactions between groundwater and surface water: The state of the science: Hydrogeology Journal, v. 10, no. 1, p. 52-67, https://doi.org/10.1007/s10040-001-0170-8.","startPage":"52","endPage":"67","numberOfPages":"16","costCenters":[],"links":[{"id":209470,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10040-001-0170-8"},{"id":235948,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"1","noUsgsAuthors":false,"publicationDate":"2002-01-11","publicationStatus":"PW","scienceBaseUri":"505a3cc3e4b0c8380cd63007","contributors":{"authors":[{"text":"Sophocleous, M.","contributorId":13373,"corporation":false,"usgs":true,"family":"Sophocleous","given":"M.","email":"","affiliations":[],"preferred":false,"id":403765,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

From this area, the potentiometric surface declined towards large well fields at Severndale, Arnold, and Annapolis. The ground-water levels declined to 78 feet below sea level at Severndale, 38 feet below sea level at Arnold, and 31 feet below sea level a few miles west of Annapolis. There was also a cone of depression covering a large area in Charles County that includes Waldorf, LaPlata, Indian Head, and the Morgantown power plant. The ground-water levels were as low as 173 feet below sea level at Waldorf, 126 feet below sea level at LaPlata, 112 feet below sea level at Indian Head, and 92 feet below sea level at the Morgantown power plant.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr2002448","usgsCitation":"Curtin, S.E., Andreasen, D., and Wheeler, J.C., 2002, Potentiometric Surface of the Lower Patapsco Aquifer in Southern Maryland, September 2001: U.S. Geological Survey Open-File Report 2002-448, 1 p., https://doi.org/10.3133/ofr2002448.","productDescription":"1 p.","temporalStart":"2001-09-01","temporalEnd":"2001-09-30","costCenters":[{"id":41514,"text":"Maryland-Delaware-District of Columbia Water Science Center","active":true,"usgs":true}],"links":[{"id":9036,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr02-448/","linkFileType":{"id":5,"text":"html"}},{"id":176536,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"scale":"250000","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.33333333333333,38 ], [ -77.33333333333333,39.5 ], [ -76,39.5 ], [ -76,38 ], [ -77.33333333333333,38 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad4e4b07f02db6832c9","contributors":{"authors":[{"text":"Curtin, Stephen E. securtin@usgs.gov","contributorId":3703,"corporation":false,"usgs":true,"family":"Curtin","given":"Stephen","email":"securtin@usgs.gov","middleInitial":"E.","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":true,"id":242155,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Andreasen, David C.","contributorId":59003,"corporation":false,"usgs":true,"family":"Andreasen","given":"David C.","affiliations":[],"preferred":false,"id":242157,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wheeler, Judith C.","contributorId":13620,"corporation":false,"usgs":true,"family":"Wheeler","given":"Judith","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":242156,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We also determined the oral bioavailability of methylmercury during these trials to test for age-related changes. The blood concentration-time curves for individuals dosed during feather development (initiated 35 days post hatch) were best described by a one-compartment toxicokinetic model with an elimination half-life of 3 days. The data for birds dosed following completion of feather growth (84 days post hatch) were best fitted by a two-compartment elimination model that includes an initial rapid distribution phase with a half-life of 0.9 days, followed by a slow elimination phase with a half-life of 116 days. We determined the oral bioavailability of methylmercury during the first dosing interval by comparing the ratios of the area under the blood concentration-time curves (AUC0→∞) for orally and intravenously dosed chicks. The oral bioavailability of methylmercury during the first dosing period was 0.83. We also determined bioavailability during both dosing periods using a second measure because of irregularities with intravenous results in the second period. This second bioavailability measure estimated the percentage of the dose that was deposited in the blood volume (f), and the results show that there was no difference in bioavailability among dosing periods. The results of this study highlight the importance of feather growth on the toxicokinetics of methylmercury.","language":"English","publisher":"Elsevier","doi":"10.1016/S1095-6433(02)00140-X","issn":"10956433","usgsCitation":"Fournier, F., Karasov, W.H., Kenow, K., Meyer, M., and Hines, R.K., 2002, The oral bioavailability and toxicokinetics of methylmercury in common loon (Gavia immer) chicks: Comparative Biochemistry and Physiology, Part A: Molecular & Integrative Physiology, v. 133, no. 3, p. 703-714, https://doi.org/10.1016/S1095-6433(02)00140-X.","productDescription":"12 p.","startPage":"703","endPage":"714","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":231801,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"133","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bae59e4b08c986b324022","contributors":{"authors":[{"text":"Fournier, F.","contributorId":57001,"corporation":false,"usgs":true,"family":"Fournier","given":"F.","email":"","affiliations":[],"preferred":false,"id":400252,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Karasov, W.

The mission of the agency is to provide scientific information to a??describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.a?? Prior to 1996, the USGS comprised 3 divisions or disciplines: geology, mapping, and water. Historically, the agency was most noted for cartographic products that were used widely by both government and private sector. With the inclusion of the National Biological Service into the USGS in 1996 as the Biological Resource Discipline (BRD), a living resources dimension was added to the earth sciences character of the USGS. With the addition of BRD, the bureau is able now to contribute both the physical and biological sciences to address the nation's resource management problems.

Short-term (48 h) in situ nutrient addition experiments were conducted between May and October at three sites located along the longitudinal axis of the lake. Nutrient limitation was detected in 12 of the 18 experiments conducted over 2 years. Phytoplankton responded to additions of phosphorus alone although highest chlorophyll concentrations were observed in enclosures receiving combined (P and N) additions. Growth responses were greatest at downstream sites and in late summer suggesting that those populations experience more severe nutrient limitation. Interannual variation in nutrient limitation and primary production corresponded to differences in the timing of hydrologic inputs. Above average rainfall and discharge in late-summer (July-October) of 1996 coincided with higher in-lake nutrient concentrations, increased production, and minimal nutrient limitation. During the same period in 1995, discharge was lower, nutrient concentrations were lower, and nutrient limitation of phytoplankton production was more pronounced. Our results suggest that nutrient limitation is common in this river impoundment but that modest inter-annual variability in the timing of hydrologic inputs can substantially influence seasonal and spatial patterns.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1021388315552","issn":"00188158","usgsCitation":"Bukaveckas, P., and Crain, A., 2002, Inter-annual, seasonal and spatial variability in nutrient limitation of phytoplankton production in a river impoundment: Hydrobiologia, v. 481, p. 19-31, https://doi.org/10.1023/A:1021388315552.","startPage":"19","endPage":"31","numberOfPages":"13","costCenters":[],"links":[{"id":207090,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1021388315552"},{"id":231702,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"481","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3c9fe4b0c8380cd62ed1","contributors":{"authors":[{"text":"Bukaveckas, P.A.","contributorId":87322,"corporation":false,"usgs":true,"family":"Bukaveckas","given":"P.A.","affiliations":[],"preferred":false,"id":400964,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crain, A.S.","contributorId":10833,"corporation":false,"usgs":true,"family":"Crain","given":"A.S.","email":"","affiliations":[],"preferred":false,"id":400963,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Palila and Cydia both specialize on the seed embryos of mamane but avoid eating the seed coats. Palila actively seek out and feed mamane embryos and Cydia larvae to their nestlings. Because mamane embryos contain potentially toxic levels of alkaloids, including broadly toxic quinolizidine alkaloids, and because insects often sequester alkaloids from their food plants, we focus on the questions of why palila forage upon mamane embryos and why they supplement their diet with Cydia larvae. Our data show that mamane embryos contain high amounts of potentially toxic alkaloids, but are well balanced nutritionally and contain lipids, carbohydrates, proteins, amino acids, and minerals at levels that are likely to be sufficient for maintenance and breeding. Mamane seed coats contain lower levels of alkaloids and nutrients, somewhat higher levels of phenolics, and much higher levels of nondigestible fiber. Taken together, these results suggest that palila have evolved tolerance to high levels of alkaloids and that they forage upon embryos primarily because of their availability in the habitat and high nutritional reward. Our data also suggest that Cydia are used by palila because they are readily accessible, nontoxic, and nutritious; the larvae apparently do not sequester alkaloids while feeding upon mamane seeds. Our results are interpreted with respect to the likelihood of current and historical coadaptive responses in this ecologically isolated and simplified island setting.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Chemical Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1016248502927","issn":"00980331","usgsCitation":"Banko, P., Cipollini, M., Breton, G., Paulk, E., Wink, M., and Izhaki, I., 2002, Seed chemistry of Sophora chrysophylla (mamane) in relation to diet of specialist avian seed predator Loxioides bailleui (palila) in Hawaii: Journal of Chemical Ecology, v. 28, no. 7, p. 1393-1410, https://doi.org/10.1023/A:1016248502927.","startPage":"1393","endPage":"1410","numberOfPages":"18","costCenters":[],"links":[{"id":207124,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1016248502927"},{"id":231779,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8abbe4b08c986b31733e","contributors":{"authors":[{"text":"Banko, P.C. 0000-0002-6035-9803","orcid":"https://orcid.org/0000-0002-6035-9803","contributorId":99531,"corporation":false,"usgs":true,"family":"Banko","given":"P.C.","affiliations":[],"preferred":false,"id":400980,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cipollini, M.L.","contributorId":14605,"corporation":false,"usgs":true,"family":"Cipollini","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":400975,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Breton, G.W.","contributorId":82492,"corporation":false,"usgs":true,"family":"Breton","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":400979,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Paulk, E.","contributorId":27226,"corporation":false,"usgs":true,"family":"Paulk","given":"E.","email":"","affiliations":[],"preferred":false,"id":400976,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wink, M.","contributorId":35905,"corporation":false,"usgs":true,"family":"Wink","given":"M.","email":"","affiliations":[],"preferred":false,"id":400977,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Izhaki, Ido","contributorId":53560,"corporation":false,"usgs":true,"family":"Izhaki","given":"Ido","email":"","affiliations":[],"preferred":false,"id":400978,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Experiments were conducted using synthetic solutions prepared by spiking both distilled/ deionized water and Missouri River water with the studied compounds. Sorption on Calgon WPH powdered activated carbon, reverse osmosis, and oxidation with chlorine and ozone under typical plant conditions were all shown to be effective in removing the studied antibiotics. Conversely, coagulation/flocculation/sedimentation with alum and iron salts, excess lime/soda ash softening, ultraviolet irradiation at disinfection dosages, and ion exchange were all relatively ineffective methods of antibiotic removal. This study shows that the studied antibiotics could be effectively removed using processes already in use many water treatment plants. Additional work is needed on by-product formation and the removal of other classes of antibiotics.","language":"English","publisher":"ASCE","doi":"10.1061/(ASCE)0733-9372(2002)128:3(253)","issn":"07339372","usgsCitation":"Adams, C., Wang, Y., Loftin, K., and Meyer, M., 2002, Removal of antibiotics from surface and distilled water in conventional water treatment processes: Journal of Environmental Engineering, v. 128, no. 3, p. 253-260, https://doi.org/10.1061/(ASCE)0733-9372(2002)128:3(253).","productDescription":"8 p.","startPage":"253","endPage":"260","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":233103,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207856,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)0733-9372(2002)128:3(253)"}],"volume":"128","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa725e4b0c8380cd85251","contributors":{"authors":[{"text":"Adams, C.","contributorId":88531,"corporation":false,"usgs":true,"family":"Adams","given":"C.","affiliations":[],"preferred":false,"id":402623,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wang, Y.","contributorId":64213,"corporation":false,"usgs":true,"family":"Wang","given":"Y.","affiliations":[],"preferred":false,"id":402622,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Loftin, K.","contributorId":36326,"corporation":false,"usgs":true,"family":"Loftin","given":"K.","email":"","affiliations":[],"preferred":false,"id":402621,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Meyer, M.","contributorId":92835,"corporation":false,"usgs":true,"family":"Meyer","given":"M.","affiliations":[],"preferred":false,"id":402624,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
