In the Noatak National Preserve in Alaska, white spruce (Picea glauca [Moench] Voss) forests reach their northern limit, occurring primarily on well-drained sites and as gallery forests along streams. Rolling plateaus of tundra separate the white spruce forests into disjunct stands. We examined patterns of tree age, tree growth, and tree encroachment into tundra ecosystems in six stands along the Agashashok River. Warming over the past 150 years appears to have increased tree growth and resulted in forest expansion into adjacent tundra ecosystems. The forest/tundra ecotone shifted by about 80 to 100 m into the tundra in the past 200 years, as evidenced by declining maximum tree age with distance towards the tundra. The decadal-scale pattern of tree establishment at the farthest extent of trees into the tundra (the tundra-forest ecotone) correlated with the detrended growth index for trees within the forests; climate conditions that led to higher tree growth appeared to foster tree establishment in the tundra. This recent forest expansion has occurred across topographic boundaries, from well-drained soils on slopes onto poorly drained, flatter areas of tundra. Further expansion of the forests may be limited by more severe wind exposure and poor drainage that make the majority of tundra less suitable for trees.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecoscience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1080/11956860.1999.11682538","issn":"11956860","usgsCitation":"Suarez, F., Binkley, D., Kaye, M., and Stottlemyer, R., 1999, Expansion of forest stands into tundra in the Noatak National Preserve, northwest Alaska: Écoscience, v. 6, no. 3, p. 465-470, https://doi.org/10.1080/11956860.1999.11682538.","startPage":"465","endPage":"470","numberOfPages":"6","costCenters":[],"links":[{"id":229728,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationDate":"2016-03-24","publicationStatus":"PW","scienceBaseUri":"505a0db5e4b0c8380cd53161","contributors":{"authors":[{"text":"Suarez, F.","contributorId":44676,"corporation":false,"usgs":true,"family":"Suarez","given":"F.","email":"","affiliations":[],"preferred":false,"id":388252,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Binkley, Dan","contributorId":102419,"corporation":false,"usgs":true,"family":"Binkley","given":"Dan","affiliations":[],"preferred":false,"id":388254,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kaye, Margot W.","contributorId":102031,"corporation":false,"usgs":false,"family":"Kaye","given":"Margot W.","affiliations":[],"preferred":false,"id":388253,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stottlemyer, R.","contributorId":44493,"corporation":false,"usgs":true,"family":"Stottlemyer","given":"R.","email":"","affiliations":[],"preferred":false,"id":388251,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The siliciclastics comprise the Long Key Formation and were identified in two cores collected from the middle and upper Florida Keys. A chronologic model based on new planktic foraminiferal biochronology and strontium-isotope chronology suggests the timing of siliciclastic deposition and provides a basis for regional correlation. The chronologic model, supplemented by vertical trends in quartz grain size, pattern of planktic menardiiform coiling direction, and paleoenvironmental interpretations of benthic foraminiferal assemblages, shows that the Long Key Formation contains three intervals (I-III) of varying thickness, grain-size composition, and paleowater depth. Interval I is uppermost Miocene. The quartz grains in Interval I fine upward from basal very coarse sand to fine and very fine sand. Benthic foraminifera indicate an upward shift from an outer-shelf to inner-shelf depositional environment. Interval II, deposited during the late early to early late Pliocene, contains reworked upper Miocene siliciclastics and faunas. In the upper Keys, quartz grains in Interval II range from very coarse sand that fines upward to very fine sand and then coarsens to very coarse and medium sand. In situ benthic faunas indicate an upward shift from outer-shelf to inner-shelf deposition. In the middle Keys, Interval II is different, with the quartz grains ranging primarily from medium to very fine sand. In situ benthic taxa indicate deposition on an inner shelf. In both the middle and upper Keys, the upper Pliocene siliciclastics of Interval III contain quartz grains ranging from very coarse to very fine sands that were deposited on an inner shelf. A sequence boundary between Interval I and Interval II is suggested by; an abrupt shift in the strontium-isotope chemostratigraphy; coarsening in quartz grain size above the boundary; an abrupt landward shift in depositional facies in the upper Keys core; and a distinct variation in the predominant coiling direction of the menardiiform planktic foraminifera, from fluctuating dextral-sinistral to dextral in the upper Keys core. Successive siliciclastic infilling, likely associated with eustatic sea-level change and current redeposition, formed a foundation for subsequent carbonate deposition. Deep-sea biostratigraphic techniques, integrated with ages derived from strontium-isotope chemostratigraphy, can be successfully applied to coastal-margin sequences, even though a depauperate suite of faunal markers is common.</p></div></div>","language":"English","publisher":"Society of Sedimentary Geology","doi":"10.2110/jsr.69.653","issn":"15271404","usgsCitation":"Guertin, L., and McNeill, D., 1999, Chronologic model and transgressive-regressive signatures in the late neocene siliciclastic foundation (long key formation) of the Florida keys: Journal of Sedimentary Research, v. 69, no. 3, p. 653-666, https://doi.org/10.2110/jsr.69.653.","productDescription":"14 p.","startPage":"653","endPage":"666","numberOfPages":"14","costCenters":[],"links":[{"id":229889,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f5f2e4b0c8380cd4c4e3","contributors":{"authors":[{"text":"Guertin, L.A.","contributorId":47937,"corporation":false,"usgs":true,"family":"Guertin","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":388456,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McNeill, D.F.","contributorId":68901,"corporation":false,"usgs":true,"family":"McNeill","given":"D.F.","email":"","affiliations":[],"preferred":false,"id":388457,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

A framework for examining the socioeconomic impacts associated with changes in the long-term availability of water is developed and applied to the hydrologic implications of the Canadian and British Hadley2 general circulation models (GCMs) for the 18 water resource regions in the conterminous United States. The climate projections of these two GCMs have very different implications for future water supplies and costs. The Canadian model suggests most of the nation would be much drier in the year 2030. Under the least-cost management scenario the drier climate could add nearly $105 billion to the estimated costs of balancing supplies and demands relative to the costs without climate change. Measures to protect instream flows and irrigation could result in significantly higher costs. In contrast, projections based on the Hadley model suggest water supplies would increase throughout much of the nation, reducing the costs of balancing water supplies with demands relative to the no-climate-change case.","largerWorkTitle":"Journal of the American Water Resources Association","language":"English","publisher":"American Water Resources Assoc","publisherLocation":"Herndon, VA, United States","issn":"1093474X","usgsCitation":"Frederick, K., and Schwarz, G., 1999, Socioeconomic impacts of climate change on U.S. water supplies, <i>in</i> Journal of the American Water Resources Association, v. 35, no. 6, p. 1563-1583.","startPage":"1563","endPage":"1583","numberOfPages":"21","costCenters":[],"links":[{"id":229683,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b91cbe4b08c986b319ae5","contributors":{"authors":[{"text":"Frederick, K.D.","contributorId":90063,"corporation":false,"usgs":true,"family":"Frederick","given":"K.D.","email":"","affiliations":[],"preferred":false,"id":387960,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schwarz, G.

Ranges, or maximum distances moved by individual butterflies, were typically less than 100 m. Maximum ranges were less than 1 km. These distances are similar to those reported for other lycaenid butterflies and from other studies of the Karner blue in the midwestern United States. At two sites, fewer than 2% of adults had ranges greater than 300 m, while at a third site 4.3% of adults had ranges greater than 300 m. Given typical subpopulation sizes these movement percentages suggest that few adults per generation will move between subpopulations separated by more than 300 m. Movement of individuals between subpopulation sites is important for maintaining genetic diversity within a metapopulation and for recolonizing areas following local extinctions.

We added 17 new species to Lake County's odonate records and 39 new species to the 5 previously recorded in Porter County.  Several regionally rare species were collected: Aeshna clepsydra, Enallagma cyathigerum, and Leucorrhina frigida.  Nine species listed in the historical records were missing from our collections: Hetaerina americana, Calopteryx aequabilis, Nehalennia irene, Arigomphus furcifer, Argia fumipennis violacea, Gomphus spicatus, Epitheca princeps, Libellula exusta, and Sympetrum semicinctum.

These strata, now foreshortened and fault-bounded, were originally contiguous with miogeoclinal strata to the east that formed as a passive-margin sequence along the northwestern margin of the North American continent. Seventy-five detrital zircon grains from the Adams Argillite and the Nation River Formation were analyzed in an effort to provide constraints on the original sources of the grains, and to generate a detrital zircon reference for miogeoclinal strata in the northern Cordillera. Thirty-five single zircon grains from a quartzite in the Adams Argillite yield dominant age clusters of 1047-1094 (n = 6), 1801-1868 (n = 10), and 2564-2687 (n = 5) Ma. Forty zircons extracted from a sandstone in the Nation River Formation yield clusters primarily of 424-434 (n = 6), 1815-1838 (n = 6), 1874-1921 (n = 7), and 2653-2771 (n = 4) Ma. The Early Proterozoic and Archean grains in both units probably originated in basement rocks in a broad region of the Canadian Shield. In contrast, the original igneous sources for mid-Proterozoic grains in the Adams Argillite and approximately 430 Ma grains in the Nation River Formation are more difficult to identify. Possible original sources for the mid-Proterozoic grains include: (1) the Grenville Province of eastern Laurentia, (2) the Pearya terrane along the Arctic margin, and (3) mid-Proterozoic igneous rocks that may have been widespread along or outboard of the Cordilleran margin. The approximately 430 Ma grains may have originated in: (1) arc-type sources along the Cordilleran margin, (2) the Caledonian orogen, or (3) a landmass, such as Pearya, Siberia, or crustal fragments now in northern Asia, that resided outboard of the Innuitian orogen during mid-Paleozoic time.</p></div></div>","language":"English","publisher":"Society of Sedimentary Geology","doi":"10.2110/jsr.69.135","issn":"1073130X","usgsCitation":"Gehrels, G.E., Johnsson, M.J., and Howell, D.G., 1999, Detrital zircon geochronology of the Adams Argillite and Nation River Formation, east-central Alaska, U.S.A: Journal of Sedimentary Research, v. 69, no. 1, p. 135-144, https://doi.org/10.2110/jsr.69.135.","productDescription":"10 p.","startPage":"135","endPage":"144","numberOfPages":"10","costCenters":[],"links":[{"id":229878,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fffee4b0c8380cd4f50f","contributors":{"authors":[{"text":"Gehrels, G.

The ranges in chemistry variables for feral lake trout were generally wider than those for laboratory-reared lake trout, and significant differences existed between male and female feral lake trout for several tests.

In our model, the plutons in the Glenelg (south-eastern Australia) and Wilson (northern Victoria Land) zones formed the roots of continental-margin magmatic arcs. Eastward shifting of arc magmatism resulted in the Stavely (south-eastern Australia) and Bowers (northern Victoria Land) volcanic eruptions onto oceanic forearc crust. The turbidites in the Stawell (southeastern Australia) and Robertson Bay (northern Victoria Land zones) shed from the Glenelg and Wilson zones, respectively, were deposited along the trench and onto the subducting oceanic plate. The margin was subsequently truncated by thrust faults and uplifted during the Delamerian and Ross orogenies, leading to the present-day aeromagnetic signatures.","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(1999)027<1087:ALOEPS>2.3.CO;2","issn":"00917613","usgsCitation":"Finn, C.A., Moore, D., Damaske, D., and Mackey, T., 1999, Aeromagnetic legacy of early Paleozoic subduction along the Pacific margin of Gondwana: Geology, v. 27, no. 12, p. 1087-1090, https://doi.org/10.1130/0091-7613(1999)027<1087:ALOEPS>2.3.CO;2.","productDescription":"4 p.","startPage":"1087","endPage":"1090","costCenters":[],"links":[{"id":230128,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Gondwana","volume":"27","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e734e4b0c8380cd478d9","contributors":{"authors":[{"text":"Finn, Carol A. 0000-0002-6178-0405 cfinn@usgs.gov","orcid":"https://orcid.org/0000-0002-6178-0405","contributorId":1326,"corporation":false,"usgs":true,"family":"Finn","given":"Carol","email":"cfinn@usgs.gov","middleInitial":"A.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":388203,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, D.","contributorId":105307,"corporation":false,"usgs":true,"family":"Moore","given":"D.","affiliations":[],"preferred":false,"id":388206,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Damaske, D.","contributorId":66771,"corporation":false,"usgs":true,"family":"Damaske","given":"D.","affiliations":[],"preferred":false,"id":388204,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mackey, T.","contributorId":76085,"corporation":false,"usgs":true,"family":"Mackey","given":"T.","email":"","affiliations":[],"preferred":false,"id":388205,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The daughter products 1,2‐dichloroethylene, vinyl chloride, 1,1,2‐trichloroethane, and 1,2‐dichloroethane are produced from hydrogenolysis of TCE and from PCA degradation through hydrogenolysis and dichloroelimination (reductive dechlorination) pathways. Total concentrations of TCE, PCA, and their degradation products, however, decrease to below detection levels within 0.15–0.30 m of land surface. The enhanced reductive dechlorination of TCE and PCA in the wetland sediments is associated with the naturally higher concentrations of dissolved organic carbon and the lower redox state of the groundwater compared to the aquifer.

These estimated changes in runoff primarily are the result of estimated changes in precipitation.

We examined the influence of 2 features characteristic of ephemeral systems, downstream hydrologic decay and in-channel tree growth, on the distribution, transport, and retention of woody debris following a flood having a ∼2.6-y recurrence interval in the ephemeral Kuiseb River in southwestern Africa. A total of 2105 pieces of wood were painted at 8 sites along the river channel to measure retention patterns. The flood had a peak discharge of 159 m&lt;sup&gt;3&lt;/sup&gt;/s at the upper end of the study area, decaying to &lt;1 m&lt;sup&gt;3&lt;/sup&gt;/s by 200 km downstream. Downstream export of wood from marking sites totaled 59.5% (n = 1253). Transport distances ranged from 1 to 124 km, and 34.8% (n = 436) of the exported wood was recovered. Marked wood retained within marking sites was significantly longer than exported wood (p &lt; 0.001, t-test). Once in transport, there was little correlation between wood length and distance traveled (r = 0.11, correlation analysis, n = 369). Length influenced the site of retention; material retained on debris piles was significantly longer than that stranded on channel sediments (p &lt; 0.001, t-test). In-channel growth of Faidherbia trees significantly influenced wood retention; 83.7% of marked wood not moved by the flood was associated with debris piles on Faidherbia trees. Similarly, 65% of the exported wood retained within downstream debris piles was associated with Faidherbia trees. In contrast to many perennial systems, we observed a general increase in wood retention downstream, peaking in the river's lower reaches in response to hydrologic decay. Debris piles induced sediment deposition and the formation of in-channel islands. Following flood recession, debris piles and their associated sediments provided moist, organic-rich microhabitats, which were focal points for decomposition and secondary production, mimicking patterns reported from the channels of perennial streams and rivers. The ecological significance of retentive obstacles and associated organic debris is a feature common to all fluvial ecosystems, irrespective of their hydrologic regime.</p></div></div></div></div>","language":"English","publisher":"University of Chicago Press","doi":"10.2307/1468376","issn":"08873593","usgsCitation":"Jacobson, P., Jacobson, K., Angermeier, P., and Cherry, D., 1999, Transport, retention, and ecological significance of woody debris within a large ephemeral river: Journal of the North American Benthological Society, v. 18, no. 4, p. 429-444, https://doi.org/10.2307/1468376.","productDescription":"16 p.","startPage":"429","endPage":"444","numberOfPages":"16","costCenters":[],"links":[{"id":230084,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb75de4b08c986b327210","contributors":{"authors":[{"text":"Jacobson, P.J.","contributorId":18529,"corporation":false,"usgs":true,"family":"Jacobson","given":"P.J.","email":"","affiliations":[],"preferred":false,"id":388053,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jacobson, K.M.","contributorId":105465,"corporation":false,"usgs":true,"family":"Jacobson","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":388055,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Angermeier, P.

However, it is theoretically possible that residual free chlorine in the HCl can react with dissolved organic carbon (DOC) to form chloroform via the haloform reaction. Analyses of 1501 ground water samples preserved with HCl from the U.S. Geological Survey's National Water-Quality Assessment Program indicate that chloroform was the most commonly detected VOC among 60 VOCs monitored. The DOC concentrations were not significantly larger in samples with detectable chloroform than in those with no delectable chloroform, nor was there any correlation between the concentrations of chloroform and DOC. Furthermore, chloroform was detected more frequently in shallow ground water in urban areas (28.5% of the wells sampled) than in agricultural areas (1.6% of the wells sampled), which indicates that its detection was more related to urban land-use activities than to sample acidification. These data provide strong evidence that acidification with HCl does not lead to the production of significant amounts of chloroform in ground water samples. To verify these results, an acidification study was designed to measure the concentrations of all trihalomethanes (THMs) that can form as a result of HCl preservation in ground water samples and to determine if ascorbic acid (C</span><sub>6</sub><span>H</span><sub>8</sub><span>O</span><sub>6</sub><span>) could inhibit this reaction if it did occur. This study showed that no THMs were formed as a result of HCl acidification, and that ascorbic acid had no discernible effect on the concentrations of THMs measured.</span></p>","language":"English","publisher":"Ground Water Pub.

Braided-stream, meandering-stream, deltaic and shoreline, and lacustrine sediments preserved in multi-level terraces in the northern Rio Desaguadero Valley record two high-water intervals; one between 4500 and 3900 yr BP and another between 2000 and 2200 yr BP. These wet periods were interrupted by three periods of fluvial downcutting, centered at approximately 4000 yr BP, 3600 yr BP, and after 2000 yr BP. Braided-river sediments preserved in a single terrace level in the southern Rio Desaguadero Valley record a history of nearly continuous fluvial sedimentation from at least 7000 yr BP until approximately 3200 yr BP that was followed by a single episode (post-3210 yr BP) of down-cutting and lateral migration. The deposition and subsequent fluvial downcutting of the northern strata was controlled by changes in effective moisture that can be correlated to Holocene water-level fluctuations of Lake Titicaca.
