Using the program PRESENCE, we modeled detection histories of each species based on single species occupancy modeling. We used different observers during four helicopter replicate surveys in the Kilbuck Mountains and five fixed-wing replicate surveys in the Ingakslugwat Hills near Bethel, AK. During helicopter surveys, Gyrfalcons had the highest detection probability estimate (p^;p^ 0.79; SE 0.05), followed by Golden Eagles (p^=0.68; SE 0.05), Common Ravens (p^=0.45; SE 0.17), and Rough-legged Hawks (p^=0.10; SE 0.11). Detection probabilities from fixed-wing aircraft in the Ingakslugwat Hills were similar to those from the helicopter in the Kilbuck Mountains for Gyrfalcons and Golden Eagles, but were higher for Common Ravens (p^=0.85; SE 0.06) and Rough-legged Hawks (p^=0.42; SE 0.07). Fixed-wing aircraft provided detection probability estimates and SEs in the Ingakslugwat Hills similar to or better than those from helicopter surveys in the Kilbucks and should be considered for future cliff-nesting raptor surveys where safe, low-altitude flight is possible. Overall, detection probability varied by observer experience and in some cases, by study area/aircraft type.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Raptor Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.3356/JRR-09-70.1","issn":"08921016","usgsCitation":"Booms, T., Schempf, P., McCaffery, B.J., Lindberg, M.S., and Fuller, M., 2010, Detection probability of cliff-nesting raptors during helicopter and fixed-wing aircraft surveys in western Alaska: Journal of Raptor Research, v. 44, no. 3, p. 175-187, https://doi.org/10.3356/JRR-09-70.1.","productDescription":"13 p.","startPage":"175","endPage":"187","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":475791,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3356/jrr-09-70.1","text":"Publisher Index Page"},{"id":246154,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218169,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3356/JRR-09-70.1"}],"country":"United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.45,51.21 ], [ 172.45,71.39 ], [ -129.99,71.39 ], [ -129.99,51.21 ], [ 172.45,51.21 ] ] ] } } ] }","volume":"44","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ff7ce4b0c8380cd4f207","contributors":{"authors":[{"text":"Booms, T.L.","contributorId":15387,"corporation":false,"usgs":true,"family":"Booms","given":"T.L.","affiliations":[],"preferred":false,"id":455426,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schempf, P.F.","contributorId":99261,"corporation":false,"usgs":true,"family":"Schempf","given":"P.F.","affiliations":[],"preferred":false,"id":455429,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McCaffery, B.

This method considers (1) contributing areas and travel times of groundwater flowpaths converging at individual supply wells, (2) the oxic and/or anoxic conditions encountered along each flowpath, and (3) the combined effects of hydrodynamic dispersion and contaminant- and oxic/anoxic-specific biodegradation. Contributing areas and travel times were assessed using particle tracks generated from calibrated regional groundwater flow models. These results were then used to estimate VOC concentrations relative to an unspecified initial concentration (C/C0) at individual public supply wells. The results show that the vulnerability of public supply wells to VOC contamination varies widely between different regional aquifers. Low-recharge rates, long travel times, and the predominantly oxic conditions characteristic of Basin and Range aquifers in the western United States leads to lower vulnerability to VOCs, particularly to petroleum hydrocarbons such as benzene and toluene. On the other hand, high recharge rates and short residence times characteristic of the glacial aquifers of the eastern United States leads to greater vulnerability to VOCs. These differences lead to distinct patterns of C/C0 values estimated for public supply wells characteristic of each aquifer, information that can be used by resource managers to develop monitoring plans based on relative vulnerability, to locate new public supply wells, or to make land-use management decisions.</p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6592.2010.01308.x","issn":"10693629","usgsCitation":"Kauffman, L.J., and Chapelle, F.H., 2010, Relative vulnerability of public supply wells to VOC contamination in hydrologically distinct regional aquifers: Ground Water Monitoring and Remediation, v. 30, no. 4, p. 54-63, https://doi.org/10.1111/j.1745-6592.2010.01308.x.","productDescription":"10 p.","startPage":"54","endPage":"63","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":218467,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6592.2010.01308.x"},{"id":246479,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-08-20","publicationStatus":"PW","scienceBaseUri":"505aa6a2e4b0c8380cd84f79","contributors":{"authors":[{"text":"Kauffman, Leon J. 0000-0003-4564-0362 lkauff@usgs.gov","orcid":"https://orcid.org/0000-0003-4564-0362","contributorId":1094,"corporation":false,"usgs":true,"family":"Kauffman","given":"Leon","email":"lkauff@usgs.gov","middleInitial":"J.","affiliations":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"preferred":true,"id":455926,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chapelle, Francis H. chapelle@usgs.gov","contributorId":1350,"corporation":false,"usgs":true,"family":"Chapelle","given":"Francis","email":"chapelle@usgs.gov","middleInitial":"H.","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true},{"id":559,"text":"South Carolina Water Science Center","active":true,"usgs":true}],"preferred":true,"id":455927,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Estimating transition probabilities between habitat states and modeling the factors that influence such transitions have many applications for investigating and managing disturbance-prone ecosystems. We identify the correspondence between multistate capture-recapture models and Markov models of habitat dynamics. We exploit this correspondence by fitting and comparing competing models of different ecological covariates affecting habitat transition probabilities in Florida scrub and flatwoods, a habitat important to many unique plants and animals. We subdivided a large scrub and flatwoods ecosystem along central Florida's Atlantic coast into 10-ha grid cells, which approximated average territory size of the threatened Florida Scrub-Jay (Aphelocoma coerulescens), a management indicator species. We used 1.0-m resolution aerial imagery for 1994, 1999, and 2004 to classify grid cells into four habitat quality states that were directly related to Florida Scrub-Jay source-sink dynamics and management decision making. Results showed that static site features related to fire propagation (vegetation type, edges) and temporally varying disturbances (fires, mechanical cutting) best explained transition probabilities. Results indicated that much of the scrub and flatwoods ecosystem was resistant to moving from a degraded state to a desired state without mechanical cutting, an expensive restoration tool. We used habitat models parameterized with the estimated transition probabilities to investigate the consequences of alternative management scenarios on future habitat dynamics. We recommend this multistate modeling approach as being broadly applicable for studying ecosystem, land cover, or habitat dynamics. The approach provides maximum-likelihood estimates of transition parameters, including precision measures, and can be used to assess evidence among competing ecological models that describe system dynamics. ?? 2010 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/09-0964.1","issn":"00129658","usgsCitation":"Breininger, D., Nichols, J., Duncan, B., Stolen, E.D., Carter, G., Hunt, D., and Drese, J., 2010, Multistate modeling of habitat dynamics: Factors affecting Florida scrub transition probabilities: Ecology, v. 91, no. 11, p. 3354-3364, https://doi.org/10.1890/09-0964.1.","startPage":"3354","endPage":"3364","numberOfPages":"11","costCenters":[],"links":[{"id":501689,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://stars.library.ucf.edu/facultybib2010/7018","text":"External Repository"},{"id":218528,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/09-0964.1"},{"id":246548,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"91","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a60abe4b0c8380cd715fc","contributors":{"authors":[{"text":"Breininger, D.R.","contributorId":62856,"corporation":false,"usgs":true,"family":"Breininger","given":"D.R.","affiliations":[],"preferred":false,"id":455947,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":455943,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Duncan, B.W.","contributorId":92096,"corporation":false,"usgs":true,"family":"Duncan","given":"B.W.","email":"","affiliations":[],"preferred":false,"id":455949,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stolen, Eric D.","contributorId":28432,"corporation":false,"usgs":true,"family":"Stolen","given":"Eric","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":455944,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Carter, G.M.","contributorId":54429,"corporation":false,"usgs":true,"family":"Carter","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":455945,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hunt, D.K.","contributorId":74618,"corporation":false,"usgs":true,"family":"Hunt","given":"D.K.","email":"","affiliations":[],"preferred":false,"id":455948,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Drese, J.H.","contributorId":56900,"corporation":false,"usgs":true,"family":"Drese","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":455946,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

We address principal approaches to cope with complex across-level issues in ecology by applying elements of hierarchy theory and the theory of complex adaptive systems. A top-down approach, often characterised by the use of statistical techniques, can be applied to analyse large-scale dynamics and identify constraints exerted on lower levels. Current developments are illustrated with examples from the analysis of within-community spatial patterns and large-scale vegetation patterns. A bottom-up approach allows one to elucidate how interactions of individuals shape dynamics at higher levels in a self-organisation process; e.g., population development and community composition. This may be facilitated by various modelling tools, which provide the distinction between focal levels and resulting properties. For instance, resilience in grassland communities has been analysed with a cellular automaton approach, and the driving forces in rodent population oscillations have been identified with an agent-based model. Both modelling tools illustrate the principles of analysing higher level processes by representing the interactions of basic components.The focus of most ecological investigations on either top-down or bottom-up approaches may not be appropriate, if strong cross-scale relationships predominate. Here, we propose an 'across-scale-approach', closely interweaving the inherent potentials of both approaches. This combination of analytical and synthesising approaches will enable ecologists to establish a more coherent access to cross-level interactions in ecological systems. ?? 2010 Gesellschaft f??r ??kologie.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Basic and Applied Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.baae.2010.08.002","issn":"14391791","usgsCitation":"Reuter, H., Jopp, F., Blanco-Moreno, J.M., Damgaard, C., Matsinos, Y., and DeAngelis, D., 2010, Ecological hierarchies and self-organisation - Pattern analysis, modelling and process integration across scales: Basic and Applied Ecology, v. 11, no. 7, p. 572-581, https://doi.org/10.1016/j.baae.2010.08.002.","startPage":"572","endPage":"581","numberOfPages":"10","costCenters":[],"links":[{"id":218244,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.baae.2010.08.002"},{"id":246237,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0553e4b0c8380cd50d64","contributors":{"authors":[{"text":"Reuter, H.","contributorId":45158,"corporation":false,"usgs":true,"family":"Reuter","given":"H.","email":"","affiliations":[],"preferred":false,"id":454374,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jopp, F.","contributorId":54833,"corporation":false,"usgs":true,"family":"Jopp","given":"F.","affiliations":[],"preferred":false,"id":454376,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Blanco-Moreno, J.

Spatially-limited diffuse tectonic deformation within the Northeast Caribbean Plate Boundary Zone likely led to the development of the submerged Mona Passage between Puerto Rico and the Dominican Republic. GPS geodetic data and a moderate to high level of seismicity indicate that extension within the region is ongoing. Newly-collected high-resolution multibeam bathymetry and multi-channel seismic reflection profiles and previously-collected samples are used here to determine the tectonic evolution of the Mona Passage intra-arc region. The passage is floored almost completely by Oligocene-Pliocene carbonate platform strata, which have undergone submarine and subaerial erosion. Structurally, the passage is characterized by W- to NNW-trending normal faults that offset the entire thickness of the Oligo-Pliocene carbonate platform rocks. The orientation of these faults is compatible with the NE-oriented extension vector observed in GPS data. Fault geometry best fits an oblique extension model rather than previously proposed single-phase, poly-phase, bending-moment, or rotation extension models. The intersection of these generally NW-trending faults in Mona Passage with the N-S oriented faults of Mona Canyon may reflect differing responses of the brittle upper-crust, along an arc-forearc rheological boundary, to oblique subduction along the Puerto Rico trench. Several faults within the passage, if ruptured completely, are long enough to generate earthquakes with magnitudes on the order of Mw 6.5-7. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Tectonophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.tecto.2010.07.002","issn":"00401951","usgsCitation":"Chaytor, J., and ten Brink, U., 2010, Extension in Mona Passage, Northeast Caribbean: Tectonophysics, v. 493, no. 1-2, p. 74-92, https://doi.org/10.1016/j.tecto.2010.07.002.","startPage":"74","endPage":"92","numberOfPages":"19","ipdsId":"IP-017925","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":246380,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218378,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.tecto.2010.07.002"}],"volume":"493","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0e42e4b0c8380cd53387","contributors":{"authors":[{"text":"Chaytor, J.D.","contributorId":80936,"corporation":false,"usgs":true,"family":"Chaytor","given":"J.D.","affiliations":[],"preferred":false,"id":456232,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"ten Brink, Uri S. 0000-0001-6858-3001 utenbrink@usgs.gov","orcid":"https://orcid.org/0000-0001-6858-3001","contributorId":127560,"corporation":false,"usgs":true,"family":"ten Brink","given":"Uri S.","email":"utenbrink@usgs.gov","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":false,"id":456233,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Other than costly destructive harvest methods, no technique exists to rapidly and accurately measure above-ground perennial tissue for woody plants such as Vitis vinifera (common grape vine). Data collected from grapevine trunks and cordons were used to study the accuracy of wood volume derived from laser scanning as compared with volume derived from analog measurements. A set of 10 laser scan datasets were collected for each of 36 vines from which volume was calculated using combinations of two, three, four, six and 10 scans. Likewise, analog volume measurements were made by submerging the vine trunks and cordons in water and capturing the displaced water. A regression analysis examined the relationship between digital and non-digital techniques among the 36 vines and found that the standard error drops rapidly as additional scans are added to the volume calculation process and stabilizes at the four-view geometry with an average Pearson's product moment correlation coefficient of 0.93. Estimates of digital volumes are systematically greater than those of analog volumes and can be explained by the manner in which each technique interacts with the vine tissue. This laser scanning technique yields a highly linear relationship between vine volume and tissue mass revealing a new, rapid and non-destructive method to remotely measure standing biomass. This application shows promise for use in other ecosystems such as orchards and forests. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Computers and Electronics in Agriculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.compag.2010.09.005","issn":"01681699","usgsCitation":"Keightley, K., and Bawden, G., 2010, 3D volumetric modeling of grapevine biomass using Tripod LiDAR: Computers and Electronics in Agriculture, v. 74, no. 2, p. 305-312, https://doi.org/10.1016/j.compag.2010.09.005.","startPage":"305","endPage":"312","numberOfPages":"8","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":246264,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218268,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.compag.2010.09.005"}],"volume":"74","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e25ce4b0c8380cd45af8","contributors":{"authors":[{"text":"Keightley, K.E.","contributorId":57310,"corporation":false,"usgs":true,"family":"Keightley","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":456493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bawden, G.W.","contributorId":61139,"corporation":false,"usgs":true,"family":"Bawden","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":456494,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study was conducted to describe population dynamics of sand shiners including age structure, growth, mortality, and recruitment variability in 15 non-wadeable rivers in Iowa. Fish were collected during June-August (2007–2008) using a modified Missouri trawl, a seine, and boat-mounted electrofishing. Scales were removed for age and growth analysis. A total of 3,443 fish was sampled from 15 populations across Iowa, of which 676 were aged. Iowa's sand shiner populations consisted primarily of age-1 fish (53% of all fish sampled), followed by age-2 fish (30%), age-0 fish (15%), and age-3 fish (2%). Sand shiners grew an average of 38.5 mm (SE = 5.7) during their first year, 13.8 mm (4.5) during their second year, and 9.0 mm (6.9) during their third year. Total annual mortality varied from 35.0% to 92.3% among populations with a mean of 77.9% (0.2). Incremental mortality rates were 84.5% (0.2) between age 1 and age 2, and 92.0% (0.1) between age 2 and age 3. Recruitment was highly variable, as indicated by a mean recruitment variation index of-0.12 (0.54). Overall, the sand shiner was characterized by relatively low mean age, fast growth, high mortality, and high recruitment variability.

Catch rate varied with year, season and the diel period during which sampling was conducted as well as by the interaction between year and season. Indices of abundance of age-0 and age-1 yellow perch estimated from night samples typically produced better fitting models and lower estimates of age-2 abundance than those using morning or afternoon samples, whereas indices using afternoon samples typically produced less precise and higher estimates of abundance.

In our approach, fault rupture is represented kinematically and incorporates spatial heterogeneity in slip, rupture speed, and rise time. The prescribed slip distribution is constrained to follow an inverse wavenumber-squared fall-off and the average rupture speed is set at 80% of the local shear-wave velocity, which is then adjusted such that the rupture propagates faster in regions of high slip and slower in regions of low slip. We use a Kostrov-like slip-rate function having a rise time proportional to the square root of slip, with the average rise time across the entire fault constrained empirically. Recent observations from large surface rupturing earthquakes indicate a reduction of rupture propagation speed and lengthening of rise time in the near surface, which we model by applying a 70% reduction of the rupture speed and increasing the rise time by a factor of 2 in a zone extending from the surface to a depth of 5 km. We demonstrate the fidelity of the technique by modeling the strong-motion recordings from the Imperial Valley, Loma Prieta, Landers, and Northridge earthquakes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120100057","issn":"00371106","usgsCitation":"Graves, R., and Pitarka, A., 2010, Broadband ground-motion simulation using a hybrid approach: Bulletin of the Seismological Society of America, v. 100, no. 5 A, p. 2095-2123, https://doi.org/10.1785/0120100057.","startPage":"2095","endPage":"2123","numberOfPages":"29","costCenters":[],"links":[{"id":246287,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218288,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120100057"}],"volume":"100","issue":"5 A","noUsgsAuthors":false,"publicationDate":"2010-09-20","publicationStatus":"PW","scienceBaseUri":"5059f286e4b0c8380cd4b212","contributors":{"authors":[{"text":"Graves, R.W. 0000-0001-9758-453X","orcid":"https://orcid.org/0000-0001-9758-453X","contributorId":77691,"corporation":false,"usgs":true,"family":"Graves","given":"R.W.","affiliations":[],"preferred":false,"id":456208,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pitarka, A.","contributorId":84185,"corporation":false,"usgs":true,"family":"Pitarka","given":"A.","affiliations":[],"preferred":false,"id":456209,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

However, the GOM region has the highest rate of wetland loss in the USA. Protection and management of these vital GOM habitats are critical to sustainable shrimp fisheries. Brown shrimp (Farfantepenaeus aztecus) are a major component of GOM fisheries. We present an approach for estimating the areal extent of suitable habitat for post-larval and juvenile brown shrimp in Mobile Bay, Alabama, using an existing habitat suitability index model for the northern GOM calculated from probabilistic survey of water quality and sediment data, land cover data, and submerged aquatic vegetation coverages. This estuarine scale approach is intended to support targeted protection and restoration of these habitats. These analyses indicate that approximately 60% of the area of Mobile Bay is categorized as suitable to near optimal for post-larval and juvenile shrimp and 38% of the area is marginally to minimally suitable.

We hypothesized that increased availability of grassland habitat through the Conservation Reserve Enhancement Program (CREP) has resulted in an increase or redistribution in numbers of four species of raptors in Pennsylvania since 2001. We tested this by analyzing winter raptor counts from volunteer surveys, conducted from 2001 to 2008, for Red-tailed Hawks (Buteo jamaicensis), Rough-legged Hawks (Buteo lagopus), Northern Harriers (Circus cyaneus), and American Kestrels (Falco sparverius). During that period, numbers of wintering Northern Harriers increased by more than 20% per year. Log-linear Poisson regression models show that all four species increased in the region of Pennsylvania that had the most and longest-established conservation grasslands. At the county scale (N= 67), Bayesian spatial models showed that spatial and temporal population trends of all four species were positively correlated with the amount of conservation grassland. This relationship was particularly strong for Northern Harriers, with numbers predicted to increase by 35.7% per year for each additional 1% of farmland enrolled in CREP. Our results suggest that conservation grasslands are likely the primary cause of the increase in numbers of wintering Northern Harriers in Pennsylvania since 2001. ?? 2010 The Authors.

Smolts were exposed to: control (pH 6.5, 3.4??gl-1 Al), acid and low Al (LAl: pH 5.4, 11??gl-1 Al), acid and moderate Al (MAl: pH 5.3, 42??gl-1 Al), and acid and high Al (HAl: pH 5.4, 56??gl-1 Al) for two and six days. At each time-point, smolts were sampled directly from freshwater treatment tanks and after a 24h seawater challenge. Exposure to acid/MAl and acid/HAl led to accumulation of gill Al, substantial alterations in gill morphology, reduced gill Na+/K+-ATPase (NKA) activity, and impaired ion regulation in both freshwater and seawater. Exposure to acid/MAl for six days also led to a decrease in gill mRNA expression of the apical Cl- channel (cystic fibrosis transmembrane conductance regulator I), increased apoptosis upon seawater exposure, an increase in the surface expression of mitochondria-rich cells (MRCs) within the filament epithelium of the gill, but reduced abundance of gill NKA-positive MRCs. By contrast, smolts exposed to acid and the lowest Al concentration exhibited minor gill Al accumulation, slight morphological modifications in the gill, and impaired seawater tolerance in the absence of a detectable effect on freshwater ion regulation. These impacts were accompanied by decreased cell proliferation, a slight increase in the surface expression of MRCs within the filament epithelium, but no impact on gill apoptosis or total MRC abundance was observed. However, MRCs in the gills of smolts exposed to acid/LAl exhibited morphological alterations including decreased size, staining intensity, and shape factor. We demonstrate that the seawater tolerance of Atlantic salmon smolts is extremely sensitive to acute exposure to acid and low levels of Al, and that the mechanisms underlying this depend on the time-course and severity of Al exposure. We propose that when smolts are exposed to acid and moderate to high Al concentrations, impaired seawater tolerance results from extensive gill Al accumulation, damage to the epithelium, reduced MRC and transport protein abundance, and a synergistic stimulation of apoptosis in the gill upon seawater exposure. When smolts are exposed to acid and low levels of Al, loss of seawater tolerance appears to be independent of these mechanisms and may result instead from a shift in the phenotype of MRCs present in the gill epithelium. ?? 2010 Elsevier B.V..","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Aquatic Toxicology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.aquatox.2010.03.016","issn":"0166445X","usgsCitation":"Monette, M., Yada, T., Matey, V., and McCormick, S., 2010, Physiological, molecular, and cellular mechanisms of impaired seawater tolerance following exposure of Atlantic salmon, Salmo salar, smolts to acid and aluminum: Aquatic Toxicology, v. 99, no. 1, p. 17-32, https://doi.org/10.1016/j.aquatox.2010.03.016.","startPage":"17","endPage":"32","numberOfPages":"16","costCenters":[],"links":[{"id":217215,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.aquatox.2010.03.016"},{"id":245142,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"99","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7b2ce4b0c8380cd792c3","contributors":{"authors":[{"text":"Monette, M.Y.","contributorId":77646,"corporation":false,"usgs":true,"family":"Monette","given":"M.Y.","affiliations":[],"preferred":false,"id":459188,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yada, T.","contributorId":20176,"corporation":false,"usgs":true,"family":"Yada","given":"T.","email":"","affiliations":[],"preferred":false,"id":459186,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Matey, V.","contributorId":103981,"corporation":false,"usgs":true,"family":"Matey","given":"V.","email":"","affiliations":[],"preferred":false,"id":459189,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McCormick, S.

Benzene-D6, toluene, ethylbenzene, o-, m- and p-xylenes and four pairs of C3- and C4-benzenes were added to an in situ microcosm and studied over a 3-year period. The microcosm allowed for a mass-balance approach and quantification of hydrocarbon biodegradation rates within a well-defined iron-reducing zone of the anoxic plume. Among the BTEX compounds, the apparent order of persistence is ethylbenzene > benzene > m,p-xylenes > o-xylene ≥ toluene. Threshold concentrations were observed for several compounds in the in situ microcosm, below which degradation was not observed, even after hundreds of days. In addition, long lag times were observed before the onset of degradation of benzene or ethylbenzene. The isomer-specific degradation patterns were compared to observations from a multi-year study conducted using data collected from monitoring wells along a flowpath in the contaminant plume. The data were fit with both first-order and Michaelis-Menten models. First-order kinetics provided a good fit for hydrocarbons with starting concentrations below 1 mg/L and Michaelis-Menten kinetics were a better fit when starting concentrations were above 1 mg/L, as was the case for benzene. The biodegradation rate data from this study were also compared to rates from other investigations reported in the literature.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Contaminant Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jconhyd.2009.12.001","issn":"01697722","usgsCitation":"Cozzarelli, I., Bekins, B., Eganhouse, R., Warren, E., and Essaid, H., 2010, In situ measurements of volatile aromatic hydrocarbon biodegradation rates in groundwater: Journal of Contaminant Hydrology, v. 111, no. 1-4, p. 48-64, https://doi.org/10.1016/j.jconhyd.2009.12.001.","productDescription":"17 p.","startPage":"48","endPage":"64","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":241845,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214151,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jconhyd.2009.12.001"}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -94.94943,47.424564 ], [ -94.94943,47.5269 ], [ -94.799758,47.5269 ], [ -94.799758,47.424564 ], [ -94.94943,47.424564 ] ] ] } } ] }","volume":"111","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a39a7e4b0c8380cd619c6","contributors":{"authors":[{"text":"Cozzarelli, I.M. 0000-0002-5123-1007","orcid":"https://orcid.org/0000-0002-5123-1007","contributorId":22343,"corporation":false,"usgs":true,"family":"Cozzarelli","given":"I.M.","affiliations":[],"preferred":false,"id":443019,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bekins, B.A.","contributorId":98309,"corporation":false,"usgs":true,"family":"Bekins","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":443021,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Eganhouse, R.P.","contributorId":67555,"corporation":false,"usgs":true,"family":"Eganhouse","given":"R.P.","email":"","affiliations":[],"preferred":false,"id":443020,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Warren, E.","contributorId":15360,"corporation":false,"usgs":true,"family":"Warren","given":"E.","email":"","affiliations":[],"preferred":false,"id":443017,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Essaid, H.I.","contributorId":22342,"corporation":false,"usgs":true,"family":"Essaid","given":"H.I.","email":"","affiliations":[],"preferred":false,"id":443018,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Attempting to reduce fuel loads and expedite forest regeneration in these areas, the USDA Forest Service often disrupts this cycle by the logging of fire-killed trees, replanting of conifers and killing of shrubs. We measured the effects of these treatments on live and dead fuel loads and alien species and modeled potential fire behavior and fire effects on regenerating forests. Sampling occurred in untreated, logged and herbicide-treated stands throughout the Sierra Nevada in four large fire areas 4–21 years after stand-replacing fires. Logging fire-killed trees significantly increased total available dead fuel loads in the short term but did not affect shrub cover, grass and forb cover, alien species cover or alien species richness. Despite the greater available dead fuel loads, fire behavior was not modeled to be different between logged and untreated stands, due to abundant shrub fuels in both logged and untreated stands. In contrast, the herbicide treatment directed at shrubs resulted in extremely low shrub cover, significantly greater alien species richness and significantly greater alien grass and forb cover. Grass and forb cover was strongly correlated with solar radiation on the ground, which may be the primary reason that grass and forb cover was higher in herbicide treated stands with low shrub and tree cover. Repeat burning exacerbated the alien grass problem in some stands. Although modeled surface fire flame lengths and rates of spread were found to be greater in stands dominated by shrubs, compared to low shrub cover conifer plantations, surface fire would still be intense enough to kill most trees, given their small size and low crown heights in the first two decades after planting.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.foreco.2010.03.026","usgsCitation":"McGinnis, T.W., Keeley, J.E., Stephens, S.L., and Roller, G.B., 2010, Fuel buildup and potential fire behavior after stand-replacing fires, logging fire-killed trees and herbicide shrub removal in Sierra Nevada forests: Forest Ecology and Management, v. 260, no. 1, p. 22-35, https://doi.org/10.1016/j.foreco.2010.03.026.","productDescription":"14 p.","startPage":"22","endPage":"35","ipdsId":"IP-016432","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":329332,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"260","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57fe8151e4b0824b2d1480c2","contributors":{"authors":[{"text":"McGinnis, Thomas W.","contributorId":87272,"corporation":false,"usgs":true,"family":"McGinnis","given":"Thomas","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":650242,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keeley, Jon E. 0000-0002-4564-6521 jon_keeley@usgs.gov","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":1268,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","email":"jon_keeley@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":650243,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stephens, Scott L.","contributorId":46022,"corporation":false,"usgs":false,"family":"Stephens","given":"Scott","email":"","middleInitial":"L.","affiliations":[{"id":6609,"text":"UC Berkeley","active":true,"usgs":false}],"preferred":false,"id":650244,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Roller, Gary B.","contributorId":175151,"corporation":false,"usgs":false,"family":"Roller","given":"Gary","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":650245,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We conducted two simulations using the finite difference method, and one by the finite element method, and performed qualitative and quantitative comparisons between the corresponding results. The results are in good agreement with each other; only small differences occur both in amplitude and phase between the various synthetics at ten observation points located near and away from the fault-as far as 150 km away from the fault. Using an available goodness-of-fit criterion all the comparisons scored above 8, with most above 9.2. This score would be regarded as excellent if the measurements were between recorded and synthetic seismograms. We also report results of comparisons based on time-frequency misfit criteria. Results from these two criteria can be used for calibrating the two methods for comparing seismograms. In those cases in which noticeable discrepancies occurred between the seismograms generated by the three groups, we found that they were the product of inherent characteristics of the various numerical methods used and their implementations. In particular, we found that the major source of discrepancy lies in the difference between mesh and grid representations of the same material model. Overall, however, even the largest differences in the synthetic seismograms are small. Thus, given the complexity of the simulations used in this verification, it appears that the three schemes are consistent, reliable and sufficiently accurate and robust for use in future large-scale simulations. ?? 2009 The Authors Journal compilation ?? 2009 RAS.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Journal International","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-246X.2009.04417.x","issn":"0956540X","usgsCitation":"Bielak, J., Graves, R., Olsen, K., Taborda, R., Ramirez-Guzman, L., Day, S., Ely, G., Roten, D., Jordan, T., Maechling, P., Urbanic, J., Cui, Y., and Juve, G., 2010, The ShakeOut earthquake scenario: Verification of three simulation sets: Geophysical Journal International, v. 180, no. 1, p. 375-404, https://doi.org/10.1111/j.1365-246X.2009.04417.x.","startPage":"375","endPage":"404","numberOfPages":"30","costCenters":[],"links":[{"id":487725,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-246x.2009.04417.x","text":"Publisher Index Page"},{"id":214498,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-246X.2009.04417.x"},{"id":242231,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"180","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba8e7e4b08c986b321f17","contributors":{"authors":[{"text":"Bielak, J.","contributorId":88572,"corporation":false,"usgs":true,"family":"Bielak","given":"J.","email":"","affiliations":[],"preferred":false,"id":442434,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Graves, R.W. 0000-0001-9758-453X","orcid":"https://orcid.org/0000-0001-9758-453X","contributorId":77691,"corporation":false,"usgs":true,"family":"Graves","given":"R.W.","affiliations":[],"preferred":false,"id":442432,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olsen, K.B.","contributorId":66022,"corporation":false,"usgs":true,"family":"Olsen","given":"K.B.","email":"","affiliations":[],"preferred":false,"id":442430,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Taborda, R.","contributorId":19792,"corporation":false,"usgs":true,"family":"Taborda","given":"R.","email":"","affiliations":[],"preferred":false,"id":442424,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ramirez-Guzman, L.","contributorId":60459,"corporation":false,"usgs":true,"family":"Ramirez-Guzman","given":"L.","affiliations":[],"preferred":false,"id":442429,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Day, S.M.","contributorId":41425,"corporation":false,"usgs":true,"family":"Day","given":"S.M.","email":"","affiliations":[],"preferred":false,"id":442426,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Ely, G.P.","contributorId":97719,"corporation":false,"usgs":true,"family":"Ely","given":"G.P.","email":"","affiliations":[],"preferred":false,"id":442436,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Roten, D.","contributorId":73836,"corporation":false,"usgs":true,"family":"Roten","given":"D.","affiliations":[],"preferred":false,"id":442431,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Jordan, T.H.","contributorId":83320,"corporation":false,"usgs":true,"family":"Jordan","given":"T.H.","affiliations":[],"preferred":false,"id":442433,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Maechling, P.J.","contributorId":24582,"corporation":false,"usgs":true,"family":"Maechling","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":442425,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Urbanic, J.","contributorId":47597,"corporation":false,"usgs":true,"family":"Urbanic","given":"J.","email":"","affiliations":[],"preferred":false,"id":442427,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Cui, Y.","contributorId":93717,"corporation":false,"usgs":true,"family":"Cui","given":"Y.","email":"","affiliations":[],"preferred":false,"id":442435,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Juve, G.","contributorId":49993,"corporation":false,"usgs":true,"family":"Juve","given":"G.","email":"","affiliations":[],"preferred":false,"id":442428,"contributorType":{"id":1,"text":"Authors"},"rank":13}]}}

Environmental models have been developed to predict the spread of introgression, but few studies have assessed the role of propagule pressure. We used an extensive set of fish stocking records and geographic information system (GIS) data to produce a spatially explicit index of potential propagule pressure exerted by introduced rainbow trout in the Upper Kootenay River, British Columbia, Canada. We then used logistic regression and the information-theoretic approach to test the ability of a set of environmental and spatial variables to predict the level of introgression between native westslope cutthroat trout and introduced rainbow trout. Introgression was assessed using between four and seven co-dominant, diagnostic nuclear markers at 45 sites in 31 different streams. The best model for predicting introgression included our GIS propagule pressure index and an environmental variable that accounted for the biogeoclimatic zone of the site (r<sup>2</sup> = 0.62). This model was 1.4 times more likely to explain introgression than the next-best model, which consisted of only the propagule pressure index variable. We created a composite model based on the model-averaged results of the seven top models that included environmental, spatial, and propagule pressure variables. The propagule pressure index had the highest importance weight (0.995) of all variables tested and was negatively related to sites with no introgression. This study used an index of propagule pressure and demonstrated that propagule pressure had the greatest influence on the level of introgression between a native and introduced trout in a human-induced hybrid zone. ?? 2010 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/08-0441.1","issn":"10510761","usgsCitation":"Bennett, S., Olson, J., Kershner, J.L., and Corbett, P., 2010, Propagule pressure and stream characteristics influence introgression: Cutthroat and rainbow trout in British Columbia: Ecological Applications, v. 20, no. 1, p. 263-277, https://doi.org/10.1890/08-0441.1.","startPage":"263","endPage":"277","numberOfPages":"15","costCenters":[],"links":[{"id":216752,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/08-0441.1"},{"id":244638,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8f14e4b0c8380cd7f588","contributors":{"authors":[{"text":"Bennett, S.N.","contributorId":87784,"corporation":false,"usgs":true,"family":"Bennett","given":"S.N.","email":"","affiliations":[],"preferred":false,"id":443870,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Olson, J.R.","contributorId":98976,"corporation":false,"usgs":true,"family":"Olson","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":443871,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kershner, J.

Using hierarchical linear models, we examined the relations between flow regime and young-of-year fish density using fish sampling and discharge data from three different warmwater streams in Illinois, Alabama, and Georgia. We used an information theoretic approach to evaluate the relative support for models describing hypothesized influences of five flow regime components representing: short-term high and low flows; short-term flow stability; and long-term mean flows and flow stability on fish reproductive success during fish spawning and rearing periods. We also evaluated the influence of ten fish species traits on fish reproductive success. Species traits included spawning duration, reproductive strategy, egg incubation rate, swimming locomotion morphology, general habitat preference, and food habits. Model selection results indicated that young-of-year fish density was positively related to short-term high flows during the spawning period and negatively related to flow variability during the rearing period. However, the effect of the flow regime components varied substantially among species, but was related to species traits. The effect of short-term high flows on the reproductive success was lower for species that broadcast their eggs during spawning. Species with cruiser swimming locomotion morphologies (e.g., Micropterus) also were more vulnerable to variable flows during the rearing period. Our models provide insight into the conditions and timing of flows that influence the reproductive success of warmwater stream fishes and may guide decisions related to stream regulation and management. ?? 2010 US Government.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00267-010-9511-5","issn":"0364152X","usgsCitation":"Craven, S., Peterson, J., Freeman, M.C., Kwak, T., and Irwin, E., 2010, Modeling the relations between flow regime components, species traits, and spawning success of fishes in warmwater streams: Environmental Management, v. 46, no. 2, p. 181-194, https://doi.org/10.1007/s00267-010-9511-5.","startPage":"181","endPage":"194","numberOfPages":"14","costCenters":[],"links":[{"id":216765,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00267-010-9511-5"},{"id":244652,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-06-18","publicationStatus":"PW","scienceBaseUri":"505a5c4ee4b0c8380cd6fbb5","contributors":{"authors":[{"text":"Craven, S.W.","contributorId":50009,"corporation":false,"usgs":true,"family":"Craven","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":445104,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peterson, J.T.","contributorId":30170,"corporation":false,"usgs":true,"family":"Peterson","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":445103,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Freeman, Mary C. 0000-0001-7615-6923","orcid":"https://orcid.org/0000-0001-7615-6923","contributorId":99659,"corporation":false,"usgs":true,"family":"Freeman","given":"Mary","email":"","middleInitial":"C.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":445106,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kwak, T.J.","contributorId":104236,"corporation":false,"usgs":true,"family":"Kwak","given":"T.J.","email":"","affiliations":[],"preferred":false,"id":445107,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Irwin, E.","contributorId":95721,"corporation":false,"usgs":true,"family":"Irwin","given":"E.","email":"","affiliations":[],"preferred":false,"id":445105,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Important information about tectonic processes may occur at amplitudes at and below tidal strains and pressure loading. If incorrect assumptions are made regarding the background noise in the strain data, then the estimates of tectonic signal amplitudes may be incorrect. Furthermore, the use of simplifying assumptions that data are uncorrelated can lead to incorrect results and pressure loading and tides may not be completely removed from the raw data. Instead, any algorithm used to process strainmeter data must incorporate the strong temporal correlations that are inherent with these data. The technique described here uses least squares but employs data covariance that describes the temporal correlation of strainmeter data. There are several advantages to this method since many parameters are estimated simultaneously. These parameters include: (1) functional terms that describe the underlying error model, (2) the tidal terms, (3) the pressure loading term(s), (4) amplitudes of offsets, either those from earthquakes or from the instrument, (5) rate and changes in rate, and (6) the amplitudes and time constants of either logarithmic or exponential curves that can characterize postseismic deformation or diffusion of fluids near the strainmeter. With the proper error model, realistic estimates of the standard errors of the various parameters are obtained; this is especially critical in determining the statistical significance of a suspected, tectonic strain signal. The program also provides a method of tracking the various adjustments required to process strainmeter data. In addition, the program provides several plots to assist with identifying either tectonic signals or other signals that may need to be removed before any geophysical signal can be identified.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Computers and Geosciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.cageo.2009.08.011","issn":"00983004","usgsCitation":"Langbein, J.O., 2010, Computer algorithm for analyzing and processing borehole strainmeter data: Computers & Geosciences, v. 36, no. 5, p. 611-619, https://doi.org/10.1016/j.cageo.2009.08.011.","startPage":"611","endPage":"619","numberOfPages":"9","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":217104,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.cageo.2009.08.011"},{"id":245021,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f955e4b0c8380cd4d587","contributors":{"authors":[{"text":"Langbein, John O. 0000-0002-7821-8101 langbein@usgs.gov","orcid":"https://orcid.org/0000-0002-7821-8101","contributorId":3293,"corporation":false,"usgs":true,"family":"Langbein","given":"John","email":"langbein@usgs.gov","middleInitial":"O.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":459311,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Components of the Earths climate system that vary over long timescales, such as ice sheets and vegetation, could have an important effect on this temperature sensitivity, but have often been neglected. Here we use a coupled atmosphere-ocean general circulation model to simulate the climate of the mid-Pliocene warm period (about three million years ago), and analyse the forcings and feedbacks that contributed to the relatively warm temperatures. Furthermore, we compare our simulation with proxy records of mid-Pliocene sea surface temperature. Taking these lines of evidence together, we estimate that the response of the Earth system to elevated atmospheric carbon dioxide concentrations is 30-50% greater than the response based on those fast-adjusting components of the climate system that are used traditionally to estimate climate sensitivity. We conclude that targets for the long-term stabilization of atmospheric greenhouse-gas concentrations aimed at preventing a dangerous human interference with the climate system should take into account this higher sensitivity of the Earth system. ?? 2010 Macmillan Publishers Limited.

As such, it is important to evaluate the impacts that such actions may have on both target and non-target species within a region. Understanding how species richness and composition differ as a result of management treatments can help determine potential ecological consequences. Yet it is difficult to estimate richness because traditional sampling approaches detect species at variable rates and some species are never observed. We present a framework for assessing management actions on biodiversity using a multi-species hierarchical model that estimates individual species occurrences, while accounting for imperfect detection of species. Our model incorporates species-specific responses to management treatments and local vegetation characteristics and a hierarchical component that links species at a community-level. This allows for comprehensive inferences on the whole community or on assemblages of interest. Compared to traditional species models, occurrence estimates are improved for all species, even for those that are rarely observed, resulting in more precise estimates of species richness (including species that were unobserved during sampling). We demonstrate the utility of this approach for conservation through an analysis comparing bird communities in two geographically similar study areas: one in which white-tailed deer (Odocoileus virginianus) densities have been regulated through hunting and one in which deer densities have gone unregulated. Although our results indicate that species and assemblage richness were similar in the two study areas, point-level richness was significantly influenced by local vegetation characteristics, a result that would have been underestimated had we not accounted for variability in species detection.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2009.11.016","issn":"00063207","usgsCitation":"Zipkin, E., Andrew, R.J., Dawson, D., and Bates, S., 2010, Multi-species occurrence models to evaluate the effects of conservation and management actions: Biological Conservation, v. 143, no. 2, p. 479-484, https://doi.org/10.1016/j.biocon.2009.11.016.","startPage":"479","endPage":"484","numberOfPages":"6","costCenters":[],"links":[{"id":215276,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2009.11.016"},{"id":243066,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"143","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5fc8e4b0c8380cd71129","contributors":{"authors":[{"text":"Zipkin, E.F.","contributorId":52790,"corporation":false,"usgs":true,"family":"Zipkin","given":"E.F.","affiliations":[],"preferred":false,"id":449721,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Andrew, Royle J.","contributorId":69800,"corporation":false,"usgs":true,"family":"Andrew","given":"Royle","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":449722,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dawson, D.K. 0000-0001-7531-212X","orcid":"https://orcid.org/0000-0001-7531-212X","contributorId":94752,"corporation":false,"usgs":true,"family":"Dawson","given":"D.K.","affiliations":[],"preferred":false,"id":449723,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bates, S.","contributorId":44271,"corporation":false,"usgs":true,"family":"Bates","given":"S.","email":"","affiliations":[],"preferred":false,"id":449720,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
