Many of these “western” species choose roost sites in crevices or cavities. Herein we provide an introduction to the biology of bats that roost in cavities and crevices and assess the challenges and opportunities associated with monitoring their populations. We reviewed recent studies and examined the U.S. Geological Survey Bat Population Database (BPD) for records of western bats using crevice and cavity roosts. We found records of 25 species of western bats that use crevice or cavity roosts for at least part of their annual cycle. There were relatively few (n = 92) observations or counts for these species in the BPD, representing only 6% of the observations in the database. This paucity of records likely reflects the difficulty of observing bats in such situations rather than actual use. We found no long-term data adequate for population trend analysis among this group of bats. Since the development of miniaturized radio transmitters, our knowledge about bats that roost in cavities and crevices has increased. Future challenges associated with monitoring these species will include understanding variability in the types of roosts used as well as the roost-switching behavior exhibited by many species. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Monitoring trends in bat populations of the United States and territories: Problems and prospects (Information and Technology Report 2003-0003)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Bogan, M., Cryan, P.M., Valdez, E.W., Ellison, L.E., and O’Shea, T.J., 2003, Western crevice and cavity-roosting bats, chap. <i>of</i> Monitoring trends in bat populations of the United States and territories: Problems and prospects (Information and Technology Report 2003-0003), p. 69-77.","productDescription":"9 p.","startPage":"69","endPage":"77","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":335370,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":335369,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/itr/2003/0003/report.pdf#page=79"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58a42537e4b0c825128ad447","contributors":{"authors":[{"text":"Bogan, Michael A.","contributorId":27128,"corporation":false,"usgs":true,"family":"Bogan","given":"Michael A.","affiliations":[],"preferred":false,"id":668693,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cryan, Paul M. 0000-0002-2915-8894 cryanp@usgs.gov","orcid":"https://orcid.org/0000-0002-2915-8894","contributorId":2356,"corporation":false,"usgs":true,"family":"Cryan","given":"Paul","email":"cryanp@usgs.gov","middleInitial":"M.","affiliations":[{"id":547,"text":"Rocky Mountain Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":668694,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Valdez, Ernest W. 0000-0002-7262-3069 ernie@usgs.gov","orcid":"https://orcid.org/0000-0002-7262-3069","contributorId":3600,"corporation":false,"usgs":true,"family":"Valdez","given":"Ernest","email":"ernie@usgs.gov","middleInitial":"W.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":668695,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ellison, Laura E. ellisonl@usgs.gov","contributorId":3220,"corporation":false,"usgs":true,"family":"Ellison","given":"Laura","email":"ellisonl@usgs.gov","middleInitial":"E.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":668696,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"O’Shea, Thomas J. osheat@usgs.gov","contributorId":2327,"corporation":false,"usgs":true,"family":"O’Shea","given":"Thomas","email":"osheat@usgs.gov","middleInitial":"J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":668697,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Many species and populations of native fishes have declined in recorded history and some now occur as isolated remnants of what once were larger more complex systems. Land management activities have been viewed as one cause of this problem. Fires also can have substantial effects on streams and riparian systems and may threaten the persistence of some populations of fish, particularly those that are small and isolated. Despite that, major new efforts to actively manage fires and fuels in forests throughout the region may be perceived as a threat rather than a benefit to conservation of native fishes and their habitats. The management of terrestrial and aquatic resources has often been contentious, divided among a variety of agencies with different goals and mandates. Management of forests, for example, has generally been viewed as an impact on aquatic systems. Implementation of the management-regulatory process has reinforced a uniform approach to mitigate the threats to aquatic species and habitats that may be influenced by management activities. The problems and opportunities, however, are not the same across the landscapes of interest. Attempts to streamline the regulatory process often search for generalized solutions that may oversimplify the complexity of natural systems. Significant questions regarding the influence of fire on aquatic ecosystems, changing fire regimes, and the effects of fire-related management remain unresolved and contribute to the uncertainty. We argue that management of forests and fishes can be viewed as part of the same problem, that of conservation and restoration of the natural processes that create diverse and productive ecosystems. We suggest that progress toward more integrated management of forests and native fishes will require at least three steps: (1) better integration and development of a common conceptual foundation and ecological goals; (2) attention to landscape and ecological context; and (3) recognition of uncertainty.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Forest Ecology and Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"New York, NY","doi":"10.1016/S0378-1127(03)00062-8","usgsCitation":"Rieman, B., Lee, D., Burns, D., Gresswell, R., Young, M., Stowell, R., Rinne, J., and Howell, P., 2003, Status of native fishes in the western United States and issues for fire and fuels management: Forest Ecology and Management, v. 178, no. 1-2, p. 197-211, https://doi.org/10.1016/S0378-1127(03)00062-8.","productDescription":"15 p.","startPage":"197","endPage":"211","numberOfPages":"15","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":134430,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"178","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d6e4b07f02db5de700","contributors":{"authors":[{"text":"Rieman, B.","contributorId":11178,"corporation":false,"usgs":true,"family":"Rieman","given":"B.","email":"","affiliations":[],"preferred":false,"id":324022,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lee, D.","contributorId":25534,"corporation":false,"usgs":true,"family":"Lee","given":"D.","affiliations":[],"preferred":false,"id":324024,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Burns, D.","contributorId":91260,"corporation":false,"usgs":true,"family":"Burns","given":"D.","email":"","affiliations":[],"preferred":false,"id":626859,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gresswell, Robert E.","contributorId":13194,"corporation":false,"usgs":true,"family":"Gresswell","given":"Robert E.","affiliations":[],"preferred":false,"id":324023,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Young, M.","contributorId":57428,"corporation":false,"usgs":true,"family":"Young","given":"M.","affiliations":[],"preferred":false,"id":324027,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stowell, R.","contributorId":80238,"corporation":false,"usgs":true,"family":"Stowell","given":"R.","email":"","affiliations":[],"preferred":false,"id":324028,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rinne, J.","contributorId":38121,"corporation":false,"usgs":true,"family":"Rinne","given":"J.","email":"","affiliations":[],"preferred":false,"id":324025,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Howell, P.","contributorId":38944,"corporation":false,"usgs":true,"family":"Howell","given":"P.","email":"","affiliations":[],"preferred":false,"id":324026,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

This study used an inverse variance weighting method to integrate Lake Huron sea lamprey population estimates derived from two estimation procedures: 1) prediction of the lake-wide spawning population from a regression model based on stream size and, 2) whole-lake mark and recapture estimates. In addition, we used a re-sampling procedure to evaluate the effect of trading off sampling effort between the regression and mark-recapture models. Population estimates derived from the regression model ranged from 132,000 to 377,000 while mark-recapture estimates of marked recently metamorphosed juveniles and parasitic sea lampreys ranged from 536,000 to 634,000 and 484,000 to 1,608,000, respectively. The precision of the estimates varied greatly among estimation procedures and years. The integrated estimate of the mark-recapture and spawner regression procedures ranged from 252,000 to 702,000 transformers. The re-sampling procedure indicated that the regression model is more sensitive to reduction in sampling effort than the mark-recapture model. Reliance on either the regression or mark-recapture model alone could produce misleading estimates of abundance of sea lampreys and the effect of the control program on sea lamprey abundance. These analyses indicate that the precision of the lakewide population estimate can be maximized by re-allocating sampling effort from marking sea lampreys to trapping additional streams.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0380-1330(03)70490-0","usgsCitation":"Young, R.J., Jones, M., Bence, J., McDonald, R., Mullett, K.M., and Bergstedt, R.A., 2003, Estimating parasitic sea lamprey abundance in Lake Huron from heterogenous data sources: Journal of Great Lakes Research, v. 29, p. 214-225, https://doi.org/10.1016/S0380-1330(03)70490-0.","productDescription":"12 p.","startPage":"214","endPage":"225","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133762,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc8ad","contributors":{"authors":[{"text":"Young, Robert J.","contributorId":31356,"corporation":false,"usgs":true,"family":"Young","given":"Robert","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":309602,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jones, Michael L.","contributorId":7219,"corporation":false,"usgs":false,"family":"Jones","given":"Michael L.","affiliations":[{"id":6590,"text":"Department of Fisheries and Wildlife, Michigan State University","active":true,"usgs":false}],"preferred":false,"id":309601,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bence, James R.","contributorId":95026,"corporation":false,"usgs":false,"family":"Bence","given":"James R.","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":309604,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McDonald, Rodney B.","contributorId":105678,"corporation":false,"usgs":true,"family":"McDonald","given":"Rodney B.","affiliations":[],"preferred":false,"id":309605,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Mullett, Katherine M.","contributorId":70733,"corporation":false,"usgs":true,"family":"Mullett","given":"Katherine","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":309603,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bergstedt, Roger A. rbergstedt@usgs.gov","contributorId":4174,"corporation":false,"usgs":true,"family":"Bergstedt","given":"Roger","email":"rbergstedt@usgs.gov","middleInitial":"A.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":309600,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Currently, over 3 million visitors drives through the park on Trail Ridge Road, camp in designated campgrounds, day hike, etc. each year. Many of those visitors also report using the backcountry-wilderness areas that are not easily accessible by roads or trails. Use of the backcountry is growing at RMNP and is accompanied by changing visitor expectations and preferences for wilderness management. For these reasons it is of great importance for the Park to periodically assess what types of environments and conditions wilderness users seek to facilitate a quality experience.</p><p> To assist in this effort, the Political Analysis and Science Assistance [PSAS] program / Fort Collins Center / U.S. Geological Survey, in close collaboration with personnel and volunteers from RMNP, as well as the Natural Resource Recreation and Tourism [NRRT] Department at Colorado State University, launched a research effort in the summer of 2002 to investigate visitors wilderness experiences in the Park. </p><p>Specifically, the purpose of this research was: (1) To determine what constitutes a wilderness experience; (2) To identify important places, visual features, and sounds essential to a quality wilderness experience and; (3) To determine what aspects may detract from wilderness experience. Thus, answers to these questions should provide insight for Park managers about visitors expectation for wilderness recreation and the conditions they seek for quality wilderness experiences. Ultimately, this information can be used to support wilderness management decisions within RMNP. </p><p>The social science technique of Visitor Employed Photography [VEP] was used to obtain information from visitors about wilderness experiences. Visitors were selected at random from Park-designated wilderness trails, in proportion to their use, and asked to participate in the survey. Respondents were given single use, 10-exposure cameras and photo-log diaries to record experiences. A total of 293 cameras were distributed, with a response rate of 87%. Following the development of the photos, a copy of the photos, two pertinent pages from the photo-log, and a follow-up survey were mailed to respondents. Fifty-six percent of the follow-up surveys were returned.

We sequenced a rapidly evolving portion of the mitochondrial control region in 332 birds from 16 populations. Although our sampling area covers the proposed boundary between the eastern and western subspecies, no genetic evidence to support the delineation of these subspecies was found. However, a population straddling southwestern Nevada and eastern California was found to contain an unusually high proportion of unique haplotypes, consistent with its genetic isolation from other Sage-grouse populations. Of additional interest was the lack of diversity in the two populations sampled from Washington, one of which contained only a single haplotype.

More species were captured at the most regulated site along the Green River above its confluence with the Yampa River. Within sites, more species were captured in riparian habitats than adjacent upland habitats.

Alewife weight at age was relatively constant between 1984 and the mid-1990s but decreased from the mid-1990s to 2001. Mean condition for a given alewife age was, on average, 13.7% higher during 1984&ndash;1994 than during 1995&ndash;2001. This decline in alewife condition was not a density-dependent response by the alewife population because alewife abundance trended neither upward nor downward during 1984&ndash;2001.

A logistic model was used to estimate the probability of survival among treatments, trials, species, and sizes. Mortality was minimal in all test concentrations of TFM alone and the TFM/1% niclosamide combination. Estimated survival decreased 6% for each unit increase in the relative toxicity of TFM. Survival was greater for E. complanata than for P. cataracta, and for adults relative to juveniles.

The site appears to be relatively safe for a MER landing site because of its predicted low wind velocities in mesoscale atmospheric circulation models and its low surface roughness at various scales as indicated by topographic and imaging data sets. Previously, the site's surface rocks have been interpreted to be marine sediments or lava flows. In addition, we suggest that Late Noachian to Early Hesperian collapse and mass wasting of Noachian highland rocks contributed to the deposition of detritus in the area of the ellipse. Furthermore, we document partial Late Hesperian to Early Amazonian resurfacing of the ellipse by flows and vents that may be of mud or silicate volcanic origin.

Important species (American cotton, <i>Gossypium hirsutum</i>, and lake trout, <i>Salvelinus namaycush</i>) and the industries they supported were negatively affected. Initial control efforts were unsuccessful until pesticides and application technologies were developed. For boll weevils, controls relying on pesticides evolved into an integrated program that included recommended farming practices and poisoned baits. However, the discovery of a boll weevil sex pheromone in 1964 allowed adoption of an ongoing program of eradication. Despite opposition over concept and cost, insecticides, pheromone traps, poisoned baits, and approved farming practices were used to eradicate boll weevils from Virginia, North Carolina, South Carolina, Georgia, Florida, and Alabama by 1999. Using the working back approach along the path of the original invasion, eradication was nearly completed by 2002 in Mississippi and eradication programs were underway in Arkansas, Tennessee, Oklahoma, Louisiana, and parts of Texas. Insecticide use for cotton production decreased 50 to 90%, and cotton yields and farm income increased an average of 78 kg/ha and $190 U.S./ha in areas where boll weevils were eradicated. For sea lampreys, integrated management uses lampricides, barriers to migration, trapping, and release of sterilized males. Although sea lamprey eradication is not currently feasible, recent research on larval and sex pheromones might provide the tools to make it possible. A successful eradication program for sea lampreys starting in Lake Superior and expanding to the lower Great Lakes would ultimately provide huge ecological and economic benefits by eliminating lampricide applications, removing barriers that block teleost fishes, and facilitating the recovery of lake trout. Should the opportunity arise, the concept of sea lamprey eradication should not be rejected out of hand. The successful boll weevil eradication program shows that sea lamprey eradication might be achievable.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/S0380-1330(03)70507-3","collaboration":"Out-of-print","usgsCitation":"Smith, J.W., and Swink, W.D., 2003, Boll weevil eradication: a model for sea lamprey control?: Journal of Great Lakes Research, v. 29, p. 445-455, https://doi.org/10.1016/S0380-1330(03)70507-3.","productDescription":"11 p.","startPage":"445","endPage":"455","numberOfPages":"11","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133364,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267261,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0380-1330(03)70507-3"}],"volume":"29","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1be4b07f02db60713a","contributors":{"authors":[{"text":"Smith, James W.","contributorId":47749,"corporation":false,"usgs":true,"family":"Smith","given":"James","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":309569,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Swink, William D.","contributorId":60586,"corporation":false,"usgs":true,"family":"Swink","given":"William","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":309570,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Microscopic counts, extractable DNA, and plate counts of viable aerobic copiotrophs (VAC) revealed that the top centimeter of crusted soils contained atypically large bacterial populations, tenfold larger than those in uncrusted, deeper soils. The plate counts were not always consistent with more direct estimates of microbial biomass. Bacterial populations peaked at the immediate subsurface (1-2 mm) in light-appearing, young crusts, and at the surface (0-1 mm) in well-developed, dark crusts, which corresponds to the location of cyanobacterial populations. Bacterial abundance decreased with depth below these horizons. Spatially resolved DGGE fingerprints of Bacterial 16S rRNA genes demonstrated the presence of highly diverse natural communities, but we could detect neither trends with depth in bacterial richness or diversity, nor a difference in diversity indices between crust types. Fingerprints, however, revealed the presence of marked stratification in the structure of the microbial communities, probably a result of vertical gradients in physicochemical parameters. Sequencing and phylogenetic analyses indicated that most of the naturally occurring bacteria are novel types, with low sequence similarity (83-93%) to those available in public databases. DGGE analyses of the VAC populations indicated communities of lower diversity, with most types having sequences more than 94% similar to those in public databases. Our study indicates that soil crusts represent small-scale mantles of fertility in arid ecosystems, harboring vertically structured, little-known bacterial populations that are not well represented by standard cultivation methods.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Microbial Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00248-003-1004-0","issn":"00953628","usgsCitation":"Garcia-Pichel, F., Johnson, S.L., Youngkin, D., and Belnap, J., 2003, Small-Scale Vertical Distribution of Bacterial Biomass and Diversity in Biological Soil Crusts from Arid Lands in the Colorado Plateau: Microbial Ecology, v. 46, no. 3, p. 312-321, https://doi.org/10.1007/s00248-003-1004-0.","startPage":"312","endPage":"321","numberOfPages":"10","costCenters":[],"links":[{"id":207755,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00248-003-1004-0"},{"id":232943,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b918fe4b08c986b31998a","contributors":{"authors":[{"text":"Garcia-Pichel, F.","contributorId":23910,"corporation":false,"usgs":true,"family":"Garcia-Pichel","given":"F.","affiliations":[],"preferred":false,"id":403535,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, S.

The slow-growing (mm/Ma) Fe-Mn crusts concentrate most elements above their mean concentration in the Earth’s crust. Tellurium is enriched more than any other element (up to about 50,000 times) relative to its Earth’s crustal mean of about 1 ppb, compared with 250 times for the next most enriched element.</p><p>We analyzed the Te contents for a suite of 105 bulk hydrogenetic crusts and 140 individual crust layers from the global ocean. For comparison, we analyzed 10 hydrothermal stratabound Mn-oxide samples collected from a variety of tectonic environments in the Pacific. In the Fe-Mn crust samples, Te varies from 3 to 205 ppm, with mean contents for Pacific and Atlantic samples of about 50 ppm and a mean of 39 ppm for Indian crust samples. Hydrothermal Mn samples have Te contents that range from 0.06 to 1 ppm. Continental margin Fe-Mn crusts have lower Te contents than open-ocean crusts, which is the result of dilution by detrital phases and differences in growth rates of the hydrogenetic phases.</p><p>Correlation coefficient matrices show that for hydrothermal deposits, Te has positive correlations with elements characteristic of detrital minerals. In contrast, Te in open-ocean Fe-Mn crusts usually correlates with elements characteristic of the MnO<sub>2</sub>, carbonate fluorapatite, and residual biogenic phases. In continental margin crusts, Te also correlates with FeOOH associated elements. In addition, Te is negatively correlated with water depth of occurrence and positively correlated with crust thickness. Q-mode factor analyses support these relationships. However, sequential leaching results show that most of the Te is associated with FeOOH in Fe-Mn crusts and ≤10% is leached with the MnO<sub>2</sub>.</p><p>Thermodynamic calculations indicate that Te occurs predominantly as H<sub>5</sub>TeO<sub>6</sub><sup>−</sup><span>&nbsp;</span>in ocean water. The speciation of Te in ocean water and charge balance considerations indicate that Te should be scavenged by FeOOH, which is in agreement with our leaching results. The thermodynamically more stable Te(IV) is less abundant by factors of 2 to 3.5 than Te(VI) in ocean water. This can be explained by preferential (not exclusive) scavenging of Te(IV) by FeOOH at the Fe-Mn crust surface and by Fe-Mn colloids in the water column. We propose a model in which the extreme enrichment of Te in Fe-Mn crusts is likely the result of an oxidation reaction on the surface of FeOOH. A similar oxidation process has been confirmed for Co, Ce, and Tl at the surface of MnO<sub>2</sub><span>&nbsp;</span>in crusts, but has not been suggested previously to occur in association with FeOOH in Fe-Mn crusts. Mass-balance considerations indicate that ocean floor Fe-Mn deposits are the major sink for Te in the oceans. The concentration and redox chemistry of Te in the global ocean are likely controlled by scavenging on Fe-Mn colloids in the water column and Fe-Mn deposits on the ocean floor, as is also the case for Ce.</p></div></div></div><ul id=\"issue-navigation\" class=\"issue-navigation u-margin-s-bottom u-bg-grey1\"></ul>","language":"English","publisher":"Elsevier","doi":"10.1016/S0016-7037(02)01279-6","usgsCitation":"Hein, J., Koschinsky, A., and Halliday, A.N., 2003, Global occurrence of tellurium-rich ferromanganese crusts and a model for the enrichment of tellurium: Geochimica et Cosmochimica Acta, v. 67, no. 6, p. 1117-1127, https://doi.org/10.1016/S0016-7037(02)01279-6.","productDescription":"11 p.","startPage":"1117","endPage":"1127","numberOfPages":"11","costCenters":[],"links":[{"id":235019,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"67","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2950e4b0c8380cd5a850","contributors":{"authors":[{"text":"Hein, J.R. 0000-0002-5321-899X","orcid":"https://orcid.org/0000-0002-5321-899X","contributorId":61429,"corporation":false,"usgs":true,"family":"Hein","given":"J.R.","affiliations":[],"preferred":false,"id":407419,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Koschinsky, A.","contributorId":42724,"corporation":false,"usgs":true,"family":"Koschinsky","given":"A.","affiliations":[],"preferred":false,"id":407418,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halliday, A.
