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.

The Puelche Volcanic Field belongs to an intra-arc belt of silicic magmatic centers that extends, at least, 140 km north-south and lies well east of the volcanic front but nonetheless considerably west of the intraplate extensional fields of basaltic and alkaline centers of pampean Argentina. The authors' mapping has distinguished one shallow intrusive mass of early Pleistocene biotite rhyodacite (70.5% SiO</span><sub>2</sub><span>), 11 eruptive units of mid-Pleistocene high-K biotite-rhyolite lava (71.3-75.6% SiO</span><sub>2</sub><span>), and 4 eruptive units of basaltic andesite (53.95-4.9% SiO</span><sub>2</sub><span>), the conduits of which cut some of the rhyolites. Basal contacts of the rhyolite lava flows (and subjacent pyroclastic precursors) are generally scree covered, but glacial erosion has exposed internal flow structures and lithologic zonation superbly. Thicknesses of individual rhyolite lava flows range from 75 m to 400 m. Feeders for several units are well exposed. Cliff-draping unconformities and intracanyon relationships among the 11 rhyolite units show that the eruptive sequence spanned at least one glacial episode that accentuated the local relief. Lack of ice-contact features suggests, however, that all or most eruptions took place during non-glacial intervals probably between 400 ka and 100 ka. Post-eruptive glacial erosion reduced the rhyolites to several non-contiguous remnants that altogether cover 83 km</span><sup>2</sup><span>&nbsp;and represent a surviving volume of about 21 km</span><sup>3</sup><span>. Consideration of slopes, lava thicknesses, and paleotopography suggest that the original area and volume were each about three times greater. Phenocryst content of the rhyolites ranges from 1 to 12%, with plagioclase&gt;&gt;biotite&gt;FeTi oxides in all units and amphibole conspicuous in the least silicic. The chemically varied basaltic andesites range from phenocryst-poor to phenocryst-rich, exhibiting large differences in proportions of clinopyroxene, olivine, plagioclase, and xenocrystic quartz. Compositional bimodality of the volcanic field is striking, there being no Quaternary eruptive units having SiO</span><sub>2</sub><span>&nbsp;contents between 55 and 70%. Major and trace element compositions of the mafic and silicic rocks are nonetheless typical of continental-margin arc suites, not of intracontinental suites.

Properties examined from ice cores included salinity, temperature, and ice structure. Salinities measured near zero at the surface, increasing to 3–4‰ at the ice-water interface. Ice crystal texture was dominated by columnar ice, comprising 90% of the ice sampled. Surface albedos of various ice types, measured with radiometers, showed integrated shortwave albedos of 0.1 to 0.3 for melt ponds, 0.5 for bare, discolored ice, and 0.6 to 0.8 for a deteriorated surface or snow-covered ice. Aerial photography was utilized to document the distribution of open melt ponds, which decreased from 12% coverage of the ice surface in late July at 76°N to almost none in mid-August at 88°N. Most melt ponds were shallow, and depth bore no relationship to size. Sediment was pervasive from the southern Chukchi Sea to the north pole, occurring in bands or patches. It was absent in the Eurasian Arctic, where it had been observed on earlier expeditions. Calculations of reverse trajectories of the sediment-bearing floes suggest that the southernmost sediment was entrained during ice formation in the Beaufort Sea while more northerly samples probably originated in the East Siberian Sea, some as far west as the New Siberian Islands.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/98JC02607","issn":"01480227","usgsCitation":"Tucker, W.B., Gow, A.J., Meese, D., Bosworth, H., and Reimnitz, E., 1999, Physical characteristics of summer sea ice across the Arctic Ocean: Journal of Geophysical Research C: Oceans, v. 104, no.

The complex may be described in terms of two sequences of cumulus rocks, or megarhythms, that each display an upward progression from ultramafic to gabbroic composition. A transitional zone between the megarhythms is characterized by an upwardly reverse lithologic progression from gabbroic to ultramafic composition. Broad cryptic variation in mineral composition over intervals >100 m parallel changes in the lithologic abundances and suggest changes in the rate of magma supply relative to crystallization and(or) tapping of different mantle sources that had been previously depleted to different degrees.

Sediment cores were collected from nearshore and offshore sites in Lake Superior and used to evaluate spatial and temporal variations in copper loading associated with mining-related activities. Although both settings have been strongly affected by anthropogenic releases of copper, copper concentrations in nearshore cores are significantly greater than those found in offshore cores, implying that nearshore copper loading is dominated by simple deposition and burial of sediment generated from mining activities. Temporal variations in copper profiles in sediments from nearshore environments closelymimic copper production rates. Conversely, copper loading histories derived from offshore sediments are not well correlated to production rates. The offshore sediment cores, when compared with analogous cores from Lakes Ontario and Michigan, show that the average, lake-wide intensity of copper loading in Lake Superior is comparable to the other two lakes, despite the fact that Lake Superior has received the largest total burden of anthropogenic copper. Cu/Zn ratios, used to evaluate the amount of copper loading derived from mining discharges, vary strongly in nearshore environments in response to loading. Cu/Zn ratios in offshore sediments are much less variable, implying that copper loading may be regulated by additional mechanisms (solution chemistry and/or biologic uptake). Study of trace metal partitioning within Lake Superior sediments indicates that the organic fraction of the sediment contains the majority of the copper. Copper concentrations in offshore sediments are significantly correlated to organic carbon content of the sediment whereas copper concentrations in nearshore sediments are not. These findings support the model that transport and deposition of particles released from mining discharges dominate copper loading in nearshore sediments, whereas biologic uptake and settling of particulate organic matter may regulate copper loading in offshore sediments.</p></div></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/S0380-1330(99)70766-5","issn":"03801330","usgsCitation":"Kolak, J., Long, D., Kerfoot, W., Beals, T., and Eisenreich, S.J., 1999, Nearshore versus offshore copper loading in Lake Superior sediments: Implications for transport and cycling: Journal of Great Lakes Research, v. 25, no. 4, p. 611-624, https://doi.org/10.1016/S0380-1330(99)70766-5.","productDescription":"14 p.","startPage":"611","endPage":"624","numberOfPages":"14","costCenters":[],"links":[{"id":230042,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a641ee4b0c8380cd728b7","contributors":{"authors":[{"text":"Kolak, J.J.","contributorId":46246,"corporation":false,"usgs":true,"family":"Kolak","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":388044,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Long, D.T.","contributorId":67930,"corporation":false,"usgs":true,"family":"Long","given":"D.T.","email":"","affiliations":[],"preferred":false,"id":388046,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kerfoot, W.C.","contributorId":24122,"corporation":false,"usgs":true,"family":"Kerfoot","given":"W.C.","affiliations":[],"preferred":false,"id":388043,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Beals, T.M.","contributorId":92009,"corporation":false,"usgs":true,"family":"Beals","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":388047,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Eisenreich, Steven J.","contributorId":66001,"corporation":false,"usgs":false,"family":"Eisenreich","given":"Steven","email":"","middleInitial":"J.","affiliations":[{"id":6626,"text":"University of Minnesota","active":true,"usgs":false}],"preferred":false,"id":388045,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Using seven existing walkup towers at this stand, high frequency velocity, temperature, water vapour and carbon dioxide concentrations were measured at 15.5 m above the ground surface from October 6 to 10 in 1997. These seven towers were separated by at least 100m from each other. The objective of this study was to examine whether single tower turbulence statistics measurements represent the flow properties of RSL turbulence above a uniform even-aged managed loblolly pine forest as a best-case scenario for natural forested ecosystems. From the intensive space-time series measurements, it was demonstrated that standard deviations of longitudinal and vertical velocities (σ<sub>u</sub>, σ<sub>w</sub>) and temperature (σ<sub>T</sub>) are more planar homogeneous than their vertical flux of momentum (u<sub>*</sub><sup>2</sup>) and sensible heat (H) counterparts. Also, the measured H is more horizontally homogeneous when compared to fluxes of other scalar entities such as CO<sub>2</sub>and water vapour. While the spatial variability in fluxes was significant (&gt;15 %), this unique data set confirmed that single tower measurements represent the ‘canonical’ structure of single-point RSL turbulence statistics, especially flux-variance relationships. Implications to extending the ‘moving-equilibrium’ hypothesis for RSL flows are discussed. The spatial variability in all RSL flow variables was not constant in time and varied strongly with spatially averaged friction velocity u<sub>*</sub>, especially when u<sub>*</sub><span>&nbsp;</span>was small. It is shown that flow properties derived from two-point temporal statistics such as correlation functions are more sensitive to local variability in leaf area density when compared to single point flow statistics. Specifically, that the local relationship between the reciprocal of the vertical velocity integral time scale (I<sub>w</sub>) and the arrival frequency of organized structures (ū/h) predicted from a mixing-layer theory exhibited dependence on the local leaf area index. The broader implications of these findings to the measurement and modelling of RSL flows are also discussed.</p>","language":"English","publisher":"Springer","doi":"10.1023/A:1002079602069","issn":"00068314","usgsCitation":"Katul, G., Hsieh, C., Bowling, D., Clark, K., Shurpali, N., Turnipseed, A., Albertson, J., Tu, K., Hollinger, D., Evans, B.M., Offerle, B., Anderson, D., Ellsworth, D., Vogel, C., and Oren, R., 1999, Spatial variability of turbulent fluxes in the roughness sublayer of an even-aged pine forest: Boundary-Layer Meteorology, v. 93, no. 1, p. 1-28, https://doi.org/10.1023/A:1002079602069.","productDescription":"28 p.","startPage":"1","endPage":"28","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":479561,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/2027.42/42512","text":"External Repository"},{"id":230238,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":206567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1002079602069"}],"volume":"93","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b94b6e4b08c986b31ac05","contributors":{"authors":[{"text":"Katul, G.","contributorId":15363,"corporation":false,"usgs":true,"family":"Katul","given":"G.","email":"","affiliations":[],"preferred":false,"id":387931,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hsieh, C.-I.","contributorId":72551,"corporation":false,"usgs":true,"family":"Hsieh","given":"C.-I.","email":"","affiliations":[],"preferred":false,"id":387938,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bowling, D.","contributorId":53978,"corporation":false,"usgs":true,"family":"Bowling","given":"D.","email":"","affiliations":[],"preferred":false,"id":387935,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Clark, K.","contributorId":71720,"corporation":false,"usgs":true,"family":"Clark","given":"K.","email":"","affiliations":[],"preferred":false,"id":387937,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shurpali, N.","contributorId":88114,"corporation":false,"usgs":true,"family":"Shurpali","given":"N.","affiliations":[],"preferred":false,"id":387940,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Turnipseed, A.","contributorId":88518,"corporation":false,"usgs":true,"family":"Turnipseed","given":"A.","email":"","affiliations":[],"preferred":false,"id":387941,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Albertson, J.","contributorId":28767,"corporation":false,"usgs":true,"family":"Albertson","given":"J.","email":"","affiliations":[],"preferred":false,"id":387932,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Tu, K.","contributorId":64420,"corporation":false,"usgs":true,"family":"Tu","given":"K.","email":"","affiliations":[],"preferred":false,"id":387936,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Hollinger, D.","contributorId":33873,"corporation":false,"usgs":true,"family":"Hollinger","given":"D.","email":"","affiliations":[],"preferred":false,"id":387933,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Evans, B.

Although precise ages of accretion are unknown, slip directions are compatible with inferred plate motions during the general time frame of accretion of the McHugh Complex. The slip vectors are interpreted to preserve the convergence directions between the overriding and underriding plates, which became more oblique with time. They are not considered indicative of strain partitioning into belts of orogen-parallel and orogen-perpendicular displacements, because the kinematic data are derived from the earliest preserved structures, whereas fabrics related to strain partitioning would be expected to be superimposed on earlier accretion-related fabrics.Permian to Cretaceous melange of the McHugh Complex on the Kenai Peninsula, south-central Alaska includes blocks and belts of graywacke, argillite, limestone, chert, basalt, gabbro, and ultramafic rocks, intruded by a variety of igneous rocks.

Antrozous pallidus was gone. A maternity colony of Myotis velifer no longer existed. Tadarida brasiliensis was rare in 1997 compared to 1972; aggregations of Myotis yumanensis seen in 1972 were missing in 1997. Breeding Corynorhinus townsendii were found in 1997, but were unknown at this location in 1972. Small numbers of Eptesicus fuscus, Myotis californicus, and Pipistrellus hesperus occupied the site in both 1972 and 1997. Additionally, museum records show that most of the bats we documented at this site also were present in 1931. Surrounding habitat did not appear substantially different between 1972 and 1997, and a reconstruction of possible impacts from bat biologists did not suggest that researchers caused the local extinctions we document. The most obvious change over 25 years was a dramatic increase in recreational use of the area.

The U.S. Fish and Wildlife Service, the U.S. Forest Service, and state agencies initiated reforestation efforts in the late 1980s to improve wildlife habitat. We surveyed restorationists responsible for reforestation in the LMAV to determine the magnitude of past and future efforts and to identify major limiting factors. Over the past 10 years, 77,698 ha have been reforested by the agencies represented in our survey and an additional 89,009 ha are targeted in the next 5 years. Oaks are the most commonly planted species and bare-root seedlings are the most commonly used planting stock. Problems with seedling availability may increase the diversity of plantings in the future. Reforestation in the LMAV is based upon principles of landscape ecology; however, local problems such as herbivory, drought, and flooding often limit success. Broad-scale hydrologic restoration is needed to fully restore the structural and functional attributes of these systems, but because of drastic and widespread hydrologic alterations and socioeconomic constraints, this goal is generally not realistic. Local hydrologic restoration and creation of specific habitat features needed by some wildlife and fish species warrant attention. More extensive analyses of plantings are needed to evaluate functional success. The Wetland Reserve Program is a positive development, but policies that provide additional financial incentives to landowners for reforestation efforts should be seriously considered.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Restoration Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1046/j.1526-100X.1999.72029.x","issn":"10612971","usgsCitation":"King, S., and Keeland, B.D., 1999, Evaluation of reforestation in the Lower Mississippi River Alluvial Valley: Restoration Ecology, v. 7, no. 4, p. 348-359, https://doi.org/10.1046/j.1526-100X.1999.72029.x.","startPage":"348","endPage":"359","numberOfPages":"12","costCenters":[],"links":[{"id":206517,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1526-100X.1999.72029.x"},{"id":230081,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"4","noUsgsAuthors":false,"publicationDate":"2002-01-05","publicationStatus":"PW","scienceBaseUri":"505a0cb6e4b0c8380cd52c7b","contributors":{"authors":[{"text":"King, S.L.","contributorId":105663,"corporation":false,"usgs":true,"family":"King","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":387902,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keeland, B.

Because few odonate surveys were conducted in northwest Indiana in the past, a poor baseline exists for comparisons of temporal trends in odonate diversity.","language":"English","publisher":"Natural Areas Association","usgsCitation":"Smolka, G.E., Stewart, P.M., and Swinford, T.O., 1999, Distribution of odonates (dragonflies and damselflies) in the Indiana Dunes National Lakeshore and nearby lands: Natural Areas Journal, v. 19, no. 2, p. 132-141.","productDescription":"10 p.","startPage":"132","endPage":"141","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":128988,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":403929,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.jstor.org/stable/43911822"}],"country":"United States","state":"Indiana","otherGeospatial":"Indiana Dunes National Lakeshore, Lake Michigan","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.5390625,\n              41.290189955885644\n            ],\n            [\n              -86.77001953125,\n              41.290189955885644\n            ],\n            [\n              -86.77001953125,\n              41.76926321969369\n            ],\n            [\n              -87.5390625,\n              41.76926321969369\n            ],\n            [\n              -87.5390625,\n              41.290189955885644\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"19","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6fe4b07f02db6408bd","contributors":{"authors":[{"text":"Smolka, George E.","contributorId":100321,"corporation":false,"usgs":true,"family":"Smolka","given":"George","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":309207,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stewart, Paul M.","contributorId":63336,"corporation":false,"usgs":true,"family":"Stewart","given":"Paul","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":309205,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Swinford, Thomas O.","contributorId":77089,"corporation":false,"usgs":true,"family":"Swinford","given":"Thomas","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":309206,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Here we describe our efforts in Utah to merge satellite-based information with forest inventory data for the purposes of reducing the costs of estimates of forest population totals and providing spatial depiction of forest resources. We illustrate how generalized linear models can be used to construct approximately unbiased and efficient estimates of population totals while providing a mechanism for prediction in space for mapping of forest structure. We model forest type and timber volume of five tree species groups as functions of a variety of predictor variables in the northern Utah mountains. Predictor variables include elevation, aspect, slope, geographic coordinates, as well as vegetation cover types based on satellite data from both the Advanced Very High Resolution Radiometer (AVHRR) and Thematic Mapper (TM) platforms. We examine the relative precision of estimates of area by forest type and mean cubic-foot volumes under six different models, including the traditional double sampling for stratification strategy. Only very small gains in precision were realized through the use of expensive photointerpreted or TM-based data for stratification, while models based on topography and spatial coordinates alone were competitive. We also compare the predictive capability of the models through various map accuracy measures. The models including the TM-based vegetation performed best overall, while topography and spatial coordinates alone provided substantial information at very low cost.</span></p>","language":"English","publisher":"Springer","doi":"10.2307/1400496","issn":"10857117","usgsCitation":"Moisen, G.G., and Edwards, T.C., 1999, Use of generalized linear models and

Using historical presence-absence data and our own surveys, we estimated annual rates of extirpation and recolonization for several populations of the goby in southern California. As predicted, large wetlands had lower rates of extirpation than small wetlands. There was a negative but statistically nonsignificant correlation between recolonization rate and distance to the nearest northerly source population. Populations at small sites were sensitive to drought, presumably because droughts can eliminate suitable habitat at small wetlands. Populations in small wetlands have declined over time, even after accounting for variation in stream flow, supporting the species' endangered status. Our study emphasizes the need to understand metapopulation dynamics for conserving species where the unit of conservation is a local population. It is also emphasizes the importance of not treating metapopulations as identical units. Finally, our results provide a means for describing the decline of a species that is complex in time and space and provide insight into how to target protection measures among metapopulations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Conservation Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1046/j.1523-1739.1999.98016.x","issn":"08888892","usgsCitation":"Lafferty, K.D., Swift, C.C., and Ambrose, R., 1999, Extirpation and recolonization in a metapopulation of an endangered fish, the tidewater goby: Conservation Biology, v. 13, no. 6, p. 1447-1453, https://doi.org/10.1046/j.1523-1739.1999.98016.x.","startPage":"1447","endPage":"1453","numberOfPages":"7","costCenters":[],"links":[{"id":206469,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1523-1739.1999.98016.x"},{"id":229883,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"6","noUsgsAuthors":false,"publicationDate":"2001-12-24","publicationStatus":"PW","scienceBaseUri":"505a0e57e4b0c8380cd533db","contributors":{"authors":[{"text":"Lafferty, K.

Estimated mean Karner blue adult life span was less than 3.5 days. Populations exhibited protandry and about a 2:1 male:female sex ratio at population peak within a brood. 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. Therefore, prudent conservation planning should aim for a landscape with habitat patches suitable for Karner blue butterfly occupancy separated by less than 300 m.","language":"English","publisher":"Natural Areas Association","usgsCitation":"Knutson, R.L., Kwilosz, J.R., and Grundel, R., 1999, Movement patterns and population characteristics of the Karner

Significant relationships were observed between time-since-burn (difference between burn and image collection dates; 550-900 days after burn) and returns related to all polarizations. As marsh burn recovery progressed, VV returns decreased while HH and VH returns increased. Radar returns extracted from control sites adjacent to each burn-simulated nonburn marsh and were not individually or in combination significantly related to the timesince-burn. Normalized by the control data, VH-polarization explained up to 83% of the total variations. Overall, the L-band multipolarization radars estimated time-since-burn within ±59 to ±92 days.&nbsp;</p>","language":"English","publisher":"IEEE","doi":"10.1109/36.739136","issn":"01962892","usgsCitation":"Ramsey, E., Nelson, G., Sapkota, S., Laine, S., Verdi, J., and Rrasznay, S., 1999, Using multiple-polarization L-band radar to monitor marsh burn recovery: IEEE Transactions on Geoscience and Remote Sensing, v. 37, no. 1 II, p. 635-639, https://doi.org/10.1109/36.739136.","startPage":"635","endPage":"639","numberOfPages":"5","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"links":[{"id":229964,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"St. Marks National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -84.26651000976561,\n              30.071470887901302\n            ],\n            [\n              -84.10720825195312,\n              30.071470887901302\n            ],\n            [\n              -84.10720825195312,\n              30.203893976001527\n            ],\n            [\n              -84.26651000976561,\n              30.203893976001527\n            ],\n            [\n              -84.26651000976561,\n              30.071470887901302\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"37","issue":"1 II","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc07de4b08c986b32a15e","contributors":{"authors":[{"text":"Ramsey, Elijah W.
