GTOP030, the U.S. Geological Survey's (USGS) digital elevation model (DEM) of the Earth, provides the flrst global coverage of moderate resolution elevation data. The original GTOP30 data set, which was developed over a 3-year period through a collaborative effort led by the USGS, was completed in 1996 at the USGS EROS Data Center in Sioux Falls, South Dakota. The collaboration involved contributions of staffing, funding, or source data from cooperators including the National Aeronautics and Space Administration (NASA), the United Nations Environment Programme Global Resource Information Database (UNEP/GRID), the U.S. Agency for International Development (USAID), the Instituto Nacional de Estadistica Geografia e Informatica (INEGI) of Mexico, the Geographical Survey Institute (GSI) of Japan, Manaaki Whenua Landcare Research of New Zealand, and the Scientific Committee on Antarctic Research (SCAR). In 1999, work was begun on an update to the GTOP030 data set. Additional data sources are being incorporated into GTOP030 with an enhanced and improved data set planned for release in 2000.

Historical data on sulfur content of produced coals shows little variability in coal quality for individual mines and individual coal-producing counties over relatively long periods of time. If coal-using power generators follow the compliance patterns established in Phase I of the 1990 Clean Air Act Amendments, then the industry's response to the tighter Phase II emissions standards will result in large amounts of coal production shifting from higher sulfur areas to areas with lower cost low sulfur coal. One reason this shift will likely occur is that currently only 30% of U.S. coal-fired electrical generating capacity is equipped with flue-gas scrubbers. In 1995, coal mines in the higher sulfur areas of the Illinois Basin and Northern and Central Appalachia employed 78% of all coal miners (>70,000 miners). A substantial geographical redistribution of the nation's coal supplies will likely lead to economic dislocations that will reach beyond local coal-producing areas.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Geosciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","usgsCitation":"Attanasi, E.D., and Root, D.H., 1999, Coal-fired power generaion, new air quality regulations, and future U.S. coal production: Environmental Geosciences, v. 6, no. 3, p. 139-145.","productDescription":"7 p.","startPage":"139","endPage":"145","costCenters":[],"links":[{"id":281426,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd51b0e4b0b290850f40d6","contributors":{"authors":[{"text":"Attanasi, E.

Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction, and behavior of fish and wildlife, and possibly humans. Pesticides in Stream Sediment and Aquatic Biota: Distribution, Trends, and Governing Factors assesses the occurrence and behavior of pesticides in bed sediment and aquatic biota-the two major compartments of the hydrologic system where organochlorine pesticides are most likely to accumulate. This book collects, for the first time, results from several hundred monitoring studies and field experiments, ranging in scope from individual sites to the entire nation. Comprehensive tables provide concise summaries of study locations, pesticides analyzed, and study outcomes. Comprehensive and extensively illustrated, Pesticides in Stream Sediment and Aquatic Biota: Distribution, Trends, and Governing Factors evaluates the sources, environmental fate, geographic distribution, and long-term trends of pesticides in bed sediment and aquatic biota. The book focuses on organochlorine pesticides, but also assesses the potential for currently used pesticides to be found in bed sediment and aquatic biota. Topics covered in depth include the effect of land use on pesticide occurrence, mechanisms of pesticide uptake and accumulation by aquatic biota, and the environmental significance of observed levels of pesticides in stream sediment and aquatic biota.","largerWorkTitle":"Pesticides in the Hydrologic System","language":"English","publisher":"CRC Press","publisherLocation":"Boca Raton, FL","usgsCitation":"Nowell, L.H., and Capel, P.D., 1999, Pesticides in stream sediment and aquatic biota: distribution, trends, and governing factors, v. 4, 1040 p.","productDescription":"1040 p.","numberOfPages":"1040","costCenters":[{"id":453,"text":"National Water-Quality Assessment Program","active":false,"usgs":true}],"links":[{"id":256883,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":256882,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://www.crcpress.com/product/isbn/9781566704694","linkFileType":{"id":5,"text":"html"}}],"volume":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a775de4b0c8380cd78498","contributors":{"authors":[{"text":"Nowell, Lisa H. 0000-0001-5417-7264 lhnowell@usgs.gov","orcid":"https://orcid.org/0000-0001-5417-7264","contributorId":490,"corporation":false,"usgs":true,"family":"Nowell","given":"Lisa","email":"lhnowell@usgs.gov","middleInitial":"H.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":464024,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Capel, Peter D.","contributorId":44773,"corporation":false,"usgs":true,"family":"Capel","given":"Peter","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":464025,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70039191,"text":"70039191 - 1999 - Discover the many types of maps available from the U.S. Geological Survey","interactions":[],"lastModifiedDate":"2012-07-25T01:02:05","indexId":"70039191","displayToPublicDate":"2012-01-01T14:21:18","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"seriesTitle":{"id":362,"text":"General Information Product","active":false,"publicationSubtype":{"id":6}},"title":"Discover the many types of maps available from the U.S. Geological Survey","docAbstract":"This publication briefly describes various types of maps available through the U.S. Geological Survey.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/70039191","usgsCitation":"Water Resources Division, U.S. Geological Survey, 1999, Discover the many types of maps available from the U.S. Geological Survey: General Information Product, 2 Plates: 61 x 69 cm., https://doi.org/10.3133/70039191.","productDescription":"2 Plates: 61 x 69 cm.","costCenters":[],"links":[{"id":259134,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":261354,"rank":900,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/gip/70039191/plate-1.pdf"},{"id":261355,"rank":900,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/gip/70039191/plate-2.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a01ece4b0c8380cd4fdc0","contributors":{"authors":[{"text":"Water Resources Division, U.S. Geological Survey","contributorId":128075,"corporation":true,"usgs":false,"organization":"Water Resources Division, U.S. Geological Survey","id":535234,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70006965,"text":"70006965 - 1999 - Breeding of Steller's Eiders, Polysticta stelleri, on the Yukon-Kuskokwim Delta, Alaska","interactions":[],"lastModifiedDate":"2023-11-13T12:49:46.503293","indexId":"70006965","displayToPublicDate":"2012-01-01T13:37:00","publicationYear":"1999","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1163,"text":"Canadian Field-Naturalist","active":true,"publicationSubtype":{"id":10}},"title":"Breeding of Steller's Eiders, Polysticta stelleri, on the Yukon-Kuskokwim Delta, Alaska","docAbstract":"Historically, an unknown number of Steller's Elders nested along the outer coastal fringe of the Yukon-Kuskokwim Delta, Alaska, but no nests had been found since 1975.

The number of females per male varied from zero to three. Several male and territory traits were significantly correlated with number of females per male. We used multiple regression to obtain a single measure of male quality and a single measure of territory quality. These measures of male and territory quality correlated with each other and with male pairing success. We used path analysis to separate direct effects of male quality on pairing success from indirect effects due to high-quality males obtaining high-quality territories. Both direct and indirect pathways had significant effects on pairing success, and direct and indirect effects of male traits on pairing success were about equal. This study illustrates an analytical approach for estimating the relative importance of direct and indirect causal relationships in natural systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Behavioral Ecology and Sociobiology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/s002650050571","collaboration":"None","usgsCitation":"Bart, J., and Earnst, S.L., 1999, Relative importance of male and territory quality in pairing success of male rock ptarmigan (Lagopus mutus): Behavioral Ecology and Sociobiology, v. 45, no. 5, p. 355-359, https://doi.org/10.1007/s002650050571.","productDescription":"5 p.","startPage":"355","endPage":"359","numberOfPages":"5","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":258313,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":258298,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s002650050571","linkFileType":{"id":5,"text":"html"}}],"volume":"45","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa686e4b0c8380cd84ed4","contributors":{"authors":[{"text":"Bart, Jonathan jon_bart@usgs.gov","contributorId":57025,"corporation":false,"usgs":true,"family":"Bart","given":"Jonathan","email":"jon_bart@usgs.gov","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":false,"id":354453,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Earnst, Susan L. susan_earnst@usgs.gov","contributorId":4446,"corporation":false,"usgs":true,"family":"Earnst","given":"Susan","email":"susan_earnst@usgs.gov","middleInitial":"L.","affiliations":[{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":true,"id":354452,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70038775,"text":"70038775 - 1999 - Sand dunes of the northern Great Plains of Canada and the United States","interactions":[],"lastModifiedDate":"2012-06-21T01:01:41","indexId":"70038775","displayToPublicDate":"2012-01-01T10:15:10","publicationYear":"1999","noYear":false,"publicationType":{"id":5,"text":"Book chapter"},"publicationSubtype":{"id":24,"text":"Book Chapter"},"title":"Sand dunes of the northern Great Plains of Canada and the United States","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Holocene climate and environmental change in the Palliser Triangle: a geoscientific context for evaluation the impacts of climate change on the southern Canadian prairies;

Toxicity usually increased with increasing temperature and was greater in the absence of sediment. No trend was found with varying pH. A series of unidimensional parameters and multidimensional models were used to describe the changes in toxicity. Log Kow was able to explain about 40–60% of the variability in response data for aqueous exposures while molecular volume and aqueous solubility were less predictive. Likewise, the linear solvation energy relationship (LSER) model only explained 40–70% of the response variability, suggesting that factors other than solubility were most important for producing the observed response. Molecular connectivity was the most useful for describing the variability in the response. In the absence of sediment, 1χv and 3κ were best able to describe the variation in response among all compounds at each pH (70–90%). In the presence of sediment, even molecular connectivity could not describe the variability until the partitioning potential to sediment was accounted for by assuming equilibrium partitioning. After correcting for partitioning, the same molecular connectivity terms as in the aqueous exposures described most of the variability, 61–87%, except for the 11°C data where correlations were not significant. Molecular connectivity was a better tool than LSER or the unidimensional variables to explain the steric fitness of OP insecticides which was crucial to the toxicity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"SAR and QSAR in Environmental Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1080/10629369908039110","usgsCitation":"Landrum, P.F., Fisher, S.W., Hwang, H., and Hickey, J.P., 1999, Hazard evaluation of ten organophosphorous insecticides against the midge, Chironomus riparius via QSAR: SAR and QSAR in Environmental Research, v. 10, no. 5, p. 423-450, https://doi.org/10.1080/10629369908039110.","productDescription":"28 p.","startPage":"423","endPage":"450","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":263572,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":263571,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/10629369908039110"}],"volume":"10","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50bd1380e4b069d93eefc4dc","contributors":{"authors":[{"text":"Landrum, Peter F.","contributorId":20688,"corporation":false,"usgs":true,"family":"Landrum","given":"Peter","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":354553,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fisher, Susan W.","contributorId":76201,"corporation":false,"usgs":true,"family":"Fisher","given":"Susan","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":354554,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hwang, Haejo","contributorId":13116,"corporation":false,"usgs":true,"family":"Hwang","given":"Haejo","email":"","affiliations":[],"preferred":false,"id":354552,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hickey, James P.","contributorId":83460,"corporation":false,"usgs":true,"family":"Hickey","given":"James","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":354555,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70039131,"text":"70039131 - 1999 - Proceedings of the fourth biennial conference of research on the Colorado Plateau","interactions":[],"lastModifiedDate":"2017-11-25T14:20:51","indexId":"70039131","displayToPublicDate":"2012-01-01T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":6,"text":"USGS Unnumbered Series"},"seriesNumber":"1999/16","title":"Proceedings of the fourth biennial conference of research on the Colorado Plateau","docAbstract":"The 13 chapters in this book were selected from the 75 research papers presented at the Fourth Biennial Conference of Research on the Colorado Plateau.

The samples were analyzed for 85 pesticides, including 50 herbicides, 28 insecticides, and 7 degradation products, at method detection limits that ranged from 0.001 to 0.018 μg/L (micrograms per liter). Pesticides were frequently detected; however, concentrations were generally low. The pesticides most frequently detected were atrazine, in 97 percent of the samples; prometon, 96 percent; metolachlor, 95 percent; desethyl-atrazine, 91 percent; simazine, 88 percent; diazinon, 58 percent; alachlor, 56 percent; and carbaryl, 54 percent. Detection frequencies were highest during the growing season (April-September). At least one pesticide was detected in all but one of these samples, and 49 percent of the samples contained 9 or more pesticides. The numbers of pesticides detected at a given site ranged from 13 to 29.\n\nTen pesticides were detected at concentrations that exceeded established water-quality criteria. Thirty-one of these detections were in samples collected during the growing season and one during the nongrowing season. The pesticides that exceeded the U.S. Environmental Protection Agency (USEPA) maximum contaminant level for drinking water were atrazine, which exceeded 3 μg/L in four samples, and alachlor, 2 μg/L in two samples. Cyanazine exceeded the USEPA liftime health advisory level (HAL) of 1 μg/L in two samples. These eight detections occurred during runoff shortly after spring pesticide applications and represent a potential threat to municipal water supplies in the Raritan River basin. Concentrations of chlorpyrifos, chlorthalonil, diazinon, ethyl-parathion, and methyl-azinphos exceeded the chronic life criteria for the protection of aquatic life (ACQR) in 20 samples at four sites during the growing season. Dieldrin was detected in four samples and DDE in two samples at concentrations that exceeded New Jersey Department of Environmental Protection (NJDEP) human health criteria. \n\nIndividual and total-pesticide concentrations and total numbers of pesticides detected in the samples varied with season and flow conditions. Median and maximum concentrations of most of the pesticides were highest during runoff in the growing season. Pesticide concentrations were typically lower and less variable in the nongrowing season than in the growing season, regardless of changes in hydrologic conditions; however, median concentrations of most pesticides were slightly lower during runoff than during base flow. The median total-pesticide concentration and median total number of pesticides detected were highest and most variable in runoff samples in the growing season. In the nongrowing season, the median total-pesticide concentration was lowest in runoff samples and least variable during base-flow conditions. Median total numbers of pesticides were lowest and least varibale in the nongrowing season during base-flow conditions at most sites. \n\nThe highest total-pesticide concentrations were detected in samples from the two small agricultural basins (greater than 25 percent of land use is agricultural) during runoff in late spring and early summer. In general, insecticides were detected more frequently and in greater concentrations at urban sites. Concentrations of agricultural herbicides generally decreased with increasing flow at the four sites with less than 10 percent agriculture land use and increased with increasing flow at the three sites with more than 25 percent agricultural land use. Most of the pesticides that correlated positively with streamflow were detected at sites where land use in the basin would indicate the use of those particular pesticides. Most of the pesticides that correlated negatively with streamflow were present at the site in the Coastal Plain or at sites in which the land use in the basin would not indicate heavy u","language":"ENGLISH","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri994154","usgsCitation":"Reiser, R.G., 1999, Relation of pesticide concentrations to season, streamflow, and land use in seven New Jersey streams: U.S. Geological Survey Water-Resources Investigations Report 99-4154, 19 p., https://doi.org/10.3133/wri994154.","productDescription":"19 p.","costCenters":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"links":[{"id":116680,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_99_4154.gif"},{"id":24437,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/1999/4154/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"New Jersey;New York","otherGeospatial":"Long Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75.58333333333333,38.81666666666667 ], [ -75.58333333333333,41.416666666666664 ], [ -71.45,41.416666666666664 ], [ -71.45,38.81666666666667 ], [ -75.58333333333333,38.81666666666667 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67c2b6","contributors":{"authors":[{"text":"Reiser, Robert G. 0000-0001-5140-2745 rreiser@usgs.gov","orcid":"https://orcid.org/0000-0001-5140-2745","contributorId":4083,"corporation":false,"usgs":true,"family":"Reiser","given":"Robert","email":"rreiser@usgs.gov","middleInitial":"G.","affiliations":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"preferred":true,"id":201348,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70022168,"text":"70022168 - 1999 - Bioenergetics estimate of the effects of stocking density on hatchery production of smallmouth bass fingerlings","interactions":[],"lastModifiedDate":"2025-05-22T15:50:26.803329","indexId":"70022168","displayToPublicDate":"2011-01-09T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2885,"text":"North American Journal of Aquaculture","active":true,"publicationSubtype":{"id":10}},"title":"Bioenergetics estimate of the effects of stocking density on hatchery production of smallmouth bass fingerlings","docAbstract":"Production of and consumption by hatchery-reared fingerling (age-0) smallmouth bass Micropterus dolomieu at various simulated stocking densities were estimated with a bioenergetics model. Fish growth rates and pond water temperatures during the 1996 growing season at two hatcheries in Oklahoma were used in the model. Fish growth and simulated consumption and production differed greatly between the two hatcheries, probably because of differences in pond fertilization and mortality rates. Our results suggest that appropriate stocking density depends largely on prey availability as affected by pond fertilization and on fingerling mortality rates. The bioenergetics model provided a useful tool for estimating production at various stocking density rates. However, verification of physiological parameters for age-0 fish of hatchery-reared species is needed.

In all, 1,773 bottom sample stations were occupied, 3,358 km of side-scan sonar and 5,011 km of seismic reflection profiles were gathered. On the basis of these data, a surficial sediment map was created for the Maine inner continental shelf during the Year 8 project, and cores and seismic data were collected to evaluate sand thickness during Years 9 and 10. Sand covers only 8 % of the Maine shelf, and is concentrated seaward of beaches off southern Maine in water depths less than 60 m. Sand occurs in three depositional settings: (1) in shoreface deposits connected dynamically to contemporary beaches; (2) in submerged deltas associated with lower sea-level positions; and (3) in submerged lowstand shoreline positions between 50 and 60 m. Seismic profiles over the shoreface off Saco Bay, Wells Embayment, and off the Kennebec River mouth each imaged a wedge-shaped acoustic unit which tapered off between 20 and 30 m. Cores determined that this was sand that was underlain by a variable but thin (commonly 1 m) deposit of estuarine muddy sand and a thick deposit of glacial-marine mud. Off Saco Bay, more than 55 million m3 of sand exists in the shoreface, compared with about 22 million m3 on the adjacent beach and dunes. Seaward of the Kennebec River, a large delta deposited between 13 ka and the present time holds more than 300 million m3 of sand and gravel. The best sorted sand is on the surface nearshore, with increasing amounts of gravel offshore and mud beneath the surficial sand sheet. Bedforms indicate that the surficial sand is moved by waves to at least 55 m depth. Seaward of the Penobscot River, no significant sand or gravel was encountered. Muddy estuarine sediments overlie muddy glacial-marine sediment throughout the area offshore area of this river. No satisfactory explanation is offered for lack of a sandy delta seaward of Maine's largest river. Lowstand-shoreline deposits were cored in many places in Saco Bay and off the Kennebec River mouth. Datable materials from cores indicated that the lowstand occurred around 10.5 ka off the Kennebec. Cores did not penetrate glacial-marine sediment in the lowstand deposits, and seismic profiles were ambiguous about the vertical extent of sand in these units. For these reasons, no total thickness of sand was determined from the lowstand deposits, but given the area of the surficial sand, the volume is probably in the hundreds of millions of cubic meters.

These pesticides may threaten groundwater quality. Previous studies, however, suggested that the pesticides had not moved from the gravel in several sample profiles. Excavations at a closed facility revealed tremendous variability in pesticide distribution within the site. Pesticides were present below the gravel in two profiles, but the mechanism(s) for their movement were not clear. The objectives of this study were to investigate how the physical and chemical properties of the gravel influence the environmental fate of atrazine. All of the gravel samples collected and characterized contained atrazine and sufficient organic C to adsorb significant amounts of atrazine, thus retarding its movement through the gravel. Laboratory column leaching experiments, however, suggested that much of the atrazine should leach from the gravel within a year or two. A field-scale test plot was constructed to study how atrazine moves through the gravel under controlled conditions. Atrazine was “spilled” in the test plot. Atrazine moved from the gravel both vertically and horizontally. It appears that formulated product spilled on gravel will leach. A single discrete spill can give rise to phantom spills whose occurrence and distribution is not related to any specific pesticide-management practice. The apparent lack of atrazine leaching from gravel appeared to be a transient phenomenon and/or the result of sampling limitations in previous studies. The contaminated gravel clearly poses a risk to groundwater quality.

As Johnsgard (1997) remarks in his preface, the evolutionary, ecological, and behavioural questions posed by obligate brood parasites are among the most intriguing contemporary ornithological topics. Rothstein & Robinson (1998) explain that brood parasites make ideal subjects for testing the generality of models for the evolution of social and mating behaviour, foraging behaviour, spatial distribution, and vocal development, because the strategy of providing no parental care removes constraints imposed on other birds. Since Aristotle, people have been fascinated by brood parasites, but only in the past two decades has the number of investigators working on this topic reached a critical mass and created momentum that promises many breakthroughs. New studies are being completed so rapidly that a general book is inevitably out of date on some topics by the time it is published. A complete library on brood parasitism should add two recent volumes (Morrison et al. 1999; Smith et al., in press).to the three reviewed here.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Animal Behaviour","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1006/anbe.1999.1253","collaboration":"5364_Hahn.pdf","usgsCitation":"Hahn, D., 1999, [Book review] Cowbirds and Other Brood Parasites by Catherine Ortega.
