A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated, the maps are intended to show areas where managers might concentrate their attention. It may be ineffectual to manage habitat at a site for a species that rarely occurs in an area. The species account begins with a brief capsule statement, which provides the fundamental components or keys to management for the species. A section on breeding range outlines the current breeding distribution of the species in North America, including areas that could not be mapped using BBS data. The suitable habitat section describes the breeding habitat and occasionally microhabitat characteristics of the species, especially those habitats that occur in the Great Plains. Details on habitat and microhabitat requirements often provide clues to how a species will respond to a particular management practice. A table near the end of the account complements the section on suitable habitat, and lists the specific habitat characteristics for the species by individual studies. A special section on prey habitat is included for those predatory species that have more specific prey requirements. The area requirements section provides details on territory and home range sizes, minimum area requirements, and the effects of patch size, edges, and other landscape and habitat features on abundance and productivity. It may be futile to manage a small block of suitable habitat for a species that has minimum area requirements that are larger than the area being managed. The Brown-headed Cowbird (Molothrus ater) is an obligate brood parasite of many grassland birds. The section on cowbird brood parasitism summarizes rates of cowbird parasitism, host responses to parasitism, and factors that influence parasitism, such as nest concealment and host density. The impact of management depends, in part, upon a species' nesting phenology and biology. The section on breeding-season phenology and site fidelity includes details on spring arrival and fall departure for migratory populations in the Great Plains, peak breeding periods, the tendency to renest after nest failure or success, and the propensity to return to a previous breeding site. The duration and timing of breeding varies among regions and years. Species' response to management summarizes the current knowledge and major findings in the literature on the effects of different management practices on the species. The section on management recommendations complements the previous section and summarizes specific recommendations for habitat management provided in the literature. If management recommendations differ in different portions of the species' breeding range, recommendations are given separately by region. The literature cited contains references to published and unpublished literature on the management effects and habitat requirements of the species.

The study area was characterized by a claypan soil overlying a nitrate (NO31-)-enriched glacial-drift aquifer. Denitrification produced N2O fluxes of 0.2-6.9 g ha-1 hr-1 early in the growing season. Fluxes increased with increasing soil temperature, soil water potential, and soil saturation. However, greatly diminished N2O fluxes (0.001-0.09 gha-1 hr-1) occurred when soil saturation increased to 94 percent. Losses of N2O increased linearly during the day and decreased at night, probably because of declining soil temperatures. Declines in soil saturation (less than 80 percent) and soil moisture potential (less than -10 kPa) produced late season N2O fluxes (0.03-0.8 g ha-1 hr-1) attributable to nitrification. Results indicate that denitrification would not significantly reduce claypan soil NO31- concentrations.","language":"English","issn":"10583","usgsCitation":"Pomes, M., Wilkison, D., and McMahon, P., 1998, Nitrous oxide fluxes from a claypan soil overlying nitrate-enriched glacial drift: Journal of Environmental Hydrology, v. 6, p. 1-14.","productDescription":"Paper 8; 14 p.","startPage":"1","endPage":"14","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":241026,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":360964,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.hydroweb.com/journal-hydrology-1998.html"}],"volume":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6704e4b0c8380cd73120","contributors":{"authors":[{"text":"Pomes, M.L.","contributorId":84393,"corporation":false,"usgs":true,"family":"Pomes","given":"M.L.","affiliations":[],"preferred":false,"id":440455,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wilkison, D.H.","contributorId":39800,"corporation":false,"usgs":true,"family":"Wilkison","given":"D.H.","email":"","affiliations":[],"preferred":false,"id":440454,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McMahon, P.B. 0000-0001-7452-2379","orcid":"https://orcid.org/0000-0001-7452-2379","contributorId":10762,"corporation":false,"usgs":true,"family":"McMahon","given":"P.B.","affiliations":[],"preferred":false,"id":440453,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Site response is estimated at 232 mainshock and 201 aftershock sites relative to a low-amplitude site in the Santa Monica Mountains. Average amplification values are calculated for the frequency bands: 1 to 3, 3 to 5, and 5 to 7 Hz. These bands are chosen based on limitations in aftershock recording equipment at lower frequencies and reduced significance to the building inventory at higher frequencies. Site amplification factors determined at the instrumented locations are grouped by the surficial geology and contoured to produce a continuous spatial estimation of amplification.

The first interpretation would require a fault constitutive relationship in which rapid dynamic restrengthening of the fault surface occurs after passage of the rupture front, a hypothesized mechanical behavior that has been referred to as “self-healing.” The second interpretation would require sufficient spatial heterogeneity of stress drop to permit rapid equilibration of elastic stresses with the residual dynamic friction level, a condition we refer to as “geometrical constraint.” These interpretations imply contrasting predictions for the time dependence of the fault-plane shear stresses. We compare these predictions with dynamic shear stress changes for the 1992 Landers (<i>M</i><span>&nbsp;</span>7.3), 1994 Northridge (<i>M</i><span>&nbsp;</span>6.7), and 1995 Kobe (<i>M</i><span>&nbsp;</span>6.9) earthquakes. Stress changes are computed from kinematic slip models of these earthquakes, using a finite-difference method. For each event, static stress drop is highly variable spatially, with high stress-drop patches embedded in a background of low, and largely negative, stress drop. The time histories of stress change show predominantly monotonic stress change after passage of the rupture front, settling to a residual level, without significant evidence for dynamic restrengthening. The stress change at the rupture front is usually gradual rather than abrupt, probably reflecting the limited resolution inherent in the underlying kinematic inversions. On the basis of this analysis, as well as recent similar results obtained independently for the Kobe and Morgan Hill earthquakes, we conclude that, at the present time, the self-healing hypothesis is unnecessary to explain earthquake kinematics.</p></div>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/BSSA0880020512","issn":"00371106","usgsCitation":"Day, S., Yu, G., and Wald, D., 1998, Dynamic stress changes during earthquake rupture: Bulletin of the Seismological Society of America, v. 88, no. 2, p. 512-522, https://doi.org/10.1785/BSSA0880020512.","productDescription":"11 p.","startPage":"512","endPage":"522","numberOfPages":"11","costCenters":[],"links":[{"id":229696,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -118.88042975841473,\n              34.3841704408905\n            ],\n            [\n              -118.88042975841473,\n              34.06168547205796\n            ],\n            [\n              -118.11138678966469,\n              34.06168547205796\n            ],\n            [\n              -118.11138678966469,\n              34.3841704408905\n            ],\n            [\n              -118.88042975841473,\n              34.3841704408905\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"88","issue":"2","noUsgsAuthors":false,"publicationDate":"1998-04-01","publicationStatus":"PW","scienceBaseUri":"505a042ae4b0c8380cd5081d","contributors":{"authors":[{"text":"Day, S.M.","contributorId":41425,"corporation":false,"usgs":true,"family":"Day","given":"S.M.","email":"","affiliations":[],"preferred":false,"id":388712,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yu, G.","contributorId":61198,"corporation":false,"usgs":true,"family":"Yu","given":"G.","email":"","affiliations":[],"preferred":false,"id":388714,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wald, D.J. 0000-0002-1454-4514","orcid":"https://orcid.org/0000-0002-1454-4514","contributorId":43809,"corporation":false,"usgs":true,"family":"Wald","given":"D.J.","affiliations":[],"preferred":false,"id":388713,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The presence of larvae at low temperatures in March suggests that veligers are capable of delaying settlement and overwintering in the planktonic stage.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/02705060.1998.9663617","usgsCitation":"Reed, D.P., Herod, J.J., and Sickel, J.B., 1998, Variations in zebra mussel (<i>Dreissena polymorpha</i>) veliger densities throughout 1996 at Dam 52 on the lower Ohio River: Journal of Freshwater Ecology, v. 13, no. 3, p. 255-261, https://doi.org/10.1080/02705060.1998.9663617.","productDescription":"7 p.","startPage":"255","endPage":"261","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":479750,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1080/02705060.1998.9663617","text":"Publisher Index Page"},{"id":314971,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"56ab49d9e4b07ca61bfea61c","contributors":{"authors":[{"text":"Reed, Darren P.","contributorId":152651,"corporation":false,"usgs":false,"family":"Reed","given":"Darren","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":590056,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Herod, Jeffrey J.","contributorId":6966,"corporation":false,"usgs":true,"family":"Herod","given":"Jeffrey","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":590057,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sickel, James B.","contributorId":56993,"corporation":false,"usgs":true,"family":"Sickel","given":"James","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":590058,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Core mussels species have fish hosts with large movement range to disperse the parasitic larval glochidia to achieve high levels of abundance. Species associated with fish host of limited movement range require high success rate of finding fish host to achieve at least an intermediate level of abundance.

In groundwater systems, these nutrients can be quite scarce and can represent limiting elements for growth of subsurface microorganisms. In this study we examined silicate sources of these elements by characterizing the colonization and weathering of feldspars in situ using field microcosms. We found that in carbon-rich anoxic groundwaters where P and N are scarce, feldspars that contain inclusions of P-minerals such as apatite are preferentially colonized over similar feldspars without P. A microcline from S. Dakota, which contains 0.24% P2O5 but ,1 mmol/ g NH , was heavily colonized 1 4 and deeply weathered. A similar microcline from Ontario, which has no detectable P or NH , was barren of attached organisms and completely unweathered after one year. An- 1 4 orthoclase (0.28% P2O5, ;1 mmol/g NH ) was very heavily colonized and weathered, 1 4 whereas plagioclase specimens (,0.01% P, ,1 mmmol/g NH ) were uncolonized and 1 4 unweathered. In addition, the observed weathering rates are faster than expected based on laboratory rates. We propose that this system is particularly sensitive to the availability of P, and the native subsurface microorganisms have developed biochemical strategies to aggressively scavenge P (or some other essential nutrient such as Fe31 ) from resistant feldspars. The result of this interaction is that only minerals containing P will be signifi- cantly colonized, and these feldspars will be preferentially destroyed, as the subsurface microbial community scavenges a limiting nutrient.</p>","language":"English","publisher":"GeoScienceWorld ","doi":"10.2138/am-1998-11-1241","usgsCitation":"Rogers, J., Bennett, P., and Choi, W., 1998, Feldspars as a source of nutrients for microorganisms: American Mineralogist, v. 83, p. 1532-1540, https://doi.org/10.2138/am-1998-11-1241.","productDescription":"9 p.","startPage":"1532","endPage":"1540","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":338423,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","noUsgsAuthors":false,"publicationDate":"1998-12-01","publicationStatus":"PW","scienceBaseUri":"58da253be4b0543bf7fda86d","contributors":{"authors":[{"text":"Rogers, J.R.","contributorId":189897,"corporation":false,"usgs":false,"family":"Rogers","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":686422,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bennett, P.C.","contributorId":24357,"corporation":false,"usgs":true,"family":"Bennett","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":686423,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Choi, W.J.","contributorId":189896,"corporation":false,"usgs":false,"family":"Choi","given":"W.J.","email":"","affiliations":[],"preferred":false,"id":686424,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
