Recent criticisms regarding the design of monitoring programs have highlighted a failure to clearly state objectives and to address detectability and spatial sampling issues.  Here, we incorporate these criticisms to design an efficient monitoring program whose goals are to determine environmental factors which influence the current distribution and measure change in distributions over time for a suite of amphibians.  In designing the study we (1) specified a priori factors that may relate to occupancy, extinction, and colonization probabilities and (2) used the data collected (incorporating detectability) to address our scientific questions and adjust our sampling protocols.  Our results highlight the role of wetland hydroperiod and other local covariates in the probability of amphibian occupancy.  There was a change in overall occupancy probabilities for most species over the first three years of monitoring.  Most colonization and extinction estimates were constant over time (years) and space (among wetlands), with one notable exception: local extinction probabilities for Rana clamitans were lower for wetlands with longer hydroperiods.  We used information from the target system to generate scenarios of population change and gauge the ability of the current sampling to meet monitoring goals.  Our results highlight the limitations of the current sampling design, emphasizing the need for long-term efforts, with periodic re-evaluation of the program in a framework that can inform management decisions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish and Wildlife Service","doi":"10.1016/j.biocon.2008.12.002","collaboration":"7049_Mattfeldt.pdf","usgsCitation":"Mattfeldt, S., Bailey, L., and Grant, E., 2009, Monitoring multiple species: Estimating state variables and exploring the efficacy of a monitoring program: Biological Conservation, v. 142, no. 4, p. 720-737, https://doi.org/10.1016/j.biocon.2008.12.002.","productDescription":"720-737","startPage":"720","endPage":"737","numberOfPages":"18","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16982,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1016/j.biocon.2008.12.002","linkFileType":{"id":5,"text":"html"}},{"id":202267,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"142","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4fe4b07f02db6286a9","contributors":{"authors":[{"text":"Mattfeldt, S.D.","contributorId":80377,"corporation":false,"usgs":true,"family":"Mattfeldt","given":"S.D.","email":"","affiliations":[],"preferred":false,"id":343207,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bailey, L.L. 0000-0002-5959-2018","orcid":"https://orcid.org/0000-0002-5959-2018","contributorId":61006,"corporation":false,"usgs":true,"family":"Bailey","given":"L.L.","affiliations":[],"preferred":false,"id":343206,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Grant, E.H.C. 0000-0003-4401-6496","orcid":"https://orcid.org/0000-0003-4401-6496","contributorId":87242,"corporation":false,"usgs":true,"family":"Grant","given":"E.H.C.","affiliations":[],"preferred":false,"id":343208,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Shredded paper is the typical substrate in small-scale culture of L variegants, however, the effort needed to separate large numbers of individuals from decomposing paper can be prohibitive.  Burlap and nylon mesh materials were compared with paper as potential alternatives for reducing this effort.  Production and the time needed to separate L. variegatus from substrate were compared for 8 weeks among cultures with burlap, mesh, and paper substrates.   Cultures with paper increased in number and weight faster than those with burlap or mesh, but cultures using the alternative substrates also expanded their populations quickly.  The time required to separate oligochaetes from substrate was initially longer with paper and became significantly longer at 6 weeks as the paper decomposed.  Burlap frayed, but mesh exhibited no degradation.  Elevated ammonia and nitrite concentrations may have suppressed production in mesh treatments throughout the study, and ammonia was lethal in paper treatments during the final 2 weeks.  Slow initial production in burlap treatments may have been due 10 chemical applications to the fabric, which may limit the utility of burlap as a substrate.  Culture systems that maintain adequate water quality could increase production from burlap and mesh substrates to levels observed with paper substrate.  Mesh is recommended because it is nontoxic and nonbiodegradable and can significantly reduce the effort required to obtain oligochaetes and to maintain and monitor the cultures.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"North American Journal of Aquaculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"7097_Lasier.pdf","usgsCitation":"Lasier, P., 2009, Alternative substrates for culturing the freshwater oligochaete Lumbriculus variegatus: North American Journal of Aquaculture, v. 71, no. 1, p. 87-92.","productDescription":"87-92","startPage":"87","endPage":"92","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201478,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":16999,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://afs.allenpress.com/perlserv/?request=get-abstract&doi=10.1577%2FA07-104.1","linkFileType":{"id":5,"text":"html"}}],"volume":"71","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adde4b07f02db686bdf","contributors":{"authors":[{"text":"Lasier, P.

This strip is characterized by deep sandy soils found in the Evesboro and Galestown sandy loams soil series.  Within this narrow strip there exists a unique flora and fauna adapted to open dry sandy soils and occurring in small remnant patches associated with old sand mining operations and scattered protected areas.  We illustrate the uniqueness of these sites using four groups, vascular plants, tenebrionid beetles (Coleoptera: Tenebrionidae), tiger beetles (Coleoptera: Cicindelidae), and bees (Hymenoptera: Apoidea: Anthophila).  Within each of these groups, rare species were detected whose populations were locally restricted to this soil type and whose nearest known populations were often hundreds of kilometers away.  In addition to documenting the direct conservation importance of these small sandy openings along the Patuxent, we contrast the lack of any indication from vertebrate inventories that this region is unique.  The combination of plant and insect inventories appears to be a better means of clarifying a site?s importance than does any survey of a single taxonomic group.

Albatross survival has been estimated using mark-recapture data and the Cormack-Jolly-Seber (CJS) model. However, albatross exhibit skipped breeding, violating assumptions of the CJS model. Multistate modeling integrating unobservable states is a promising tool for such situations. We applied multistate models to data on Grey-headed Albatross (<i>Talassarche chrysostoma</i>) to evaluate model performance and describe demographic patterns. These included a multistate equivalent of the CJS model (MS-2), including successful and failed breeding states and ignoring temporary emigration, and three versions of a four-state multistate model that accounts for temporary emigration by integrating unobservable states: a model (MS-4) with one sample per breeding season, a robust design model (RDMS-4) with multiple samples per season and geographic closure within the season, and an open robust design model (ORDMS-4) with multiple samples per season and staggered entry and exit of animals within the season. Survival estimates from the MS-2 model were higher than those from the MS-4 model, which resulted in apparent percent relative bias averaging 2.2%. The ORDMS-4 model was more appropriate than the RDMS-4 model, given that staggered entry and exit occurred. Annual survival probability for Greyheaded Albatross at Marion Island was 0.951 ± 0.006 (SE), and the probability of skipped breeding in a subsequent year averaged 0.938 for successful and 0.163 for failed breeders. We recommend that multistate models with unobservable states, combined with robust-design sampling, be used in studies of species that exhibit temporary emigration.</p>","language":"English","publisher":"American Ornithological Society","doi":"10.1525/auk.2009.07189","usgsCitation":"Converse, S.J., Kendall, W.L., Doherty, P.F., and Ryan, P.G., 2009, Multistate models for estimation of survival and reproduction in the Grey-headed Albatross (<i>Thalassarche chrysostoma</i>): The Auk, v. 126, no. 1, p. 77-88, https://doi.org/10.1525/auk.2009.07189.","productDescription":"12 p.","startPage":"77","endPage":"88","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":487123,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/auk.2009.07189","text":"Publisher Index Page"},{"id":202188,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"126","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b48d1","contributors":{"authors":[{"text":"Converse, Sarah J. 0000-0002-3719-5441 sconverse@usgs.gov","orcid":"https://orcid.org/0000-0002-3719-5441","contributorId":3513,"corporation":false,"usgs":true,"family":"Converse","given":"Sarah","email":"sconverse@usgs.gov","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kendall, William L. wkendall@usgs.gov","contributorId":406,"corporation":false,"usgs":true,"family":"Kendall","given":"William","email":"wkendall@usgs.gov","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343212,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Doherty, Paul F.

Surveys for D. couperi at potential underground shelters conducted in late fall through early spring have been relatively successful when conducted by experienced surveyors, especially in the northern portions of the range.  However, trapping efforts for D. couperi conducted throughout the range have met with limited success.  To further evaluate detection methods, we conducted trapping and surveying from December 2002 to April 2004 in areas known to support D. couperi in southeastern Georgia.  We captured 18 D. couperi through surveys of potential underground shelters from December 2002 to March 2003 (14 person-hours per capture) and six individuals through trapping (141 trap days or 27 in-field person-hours per capture).  Trapping was most successful during early fall, a period when surveys are often less effective compared to those conducted in late fall through early spring.  We recommend a combination of surveys from mid-fall through March in conjunction with trapping, especially from late-summer through fall in the northern portions of the snake?s range.

Variation in the proportion of birds counted is a known source of error, and for robust inference it has been advocated that counts be converted to estimates of absolute population size.  We used simulation to assess nine methods for the conduct and analysis of point counts when the data included distance-related heterogeneity of individual detection probability.  Distance from the observer is a ubiquitous source of heterogeneity, because nearby birds are more easily detected than distant ones.  Several recent methods (dependent double-observer, time of first detection, time of detection, independent multiple-observer, and repeated counts) do not account for distance-related heterogeneity, at least in their simpler forms.  We assessed bias in estimates of population size by simulating counts with fixed radius w over four time intervals (occasions).  Detection probability per occasion was modeled as a half-normal function of distance with scale parameter sigma and intercept g(0) = 1.0.  Bias varied with sigma/w; values of sigma inferred from published studies were often <25 m, which suggests a bias of >50% for a 100-m fixed-radius count.  More critically, the bias of adjusted counts sometimes varied more than that of unadjusted counts, and inference from adjusted counts would be less robust.  The problem was not solved by using mixture models or including distance as a covariate.  Conventional distance sampling performed well in simulations, but its assumptions are difficult to meet in the field.  We conclude that no existing method allows effective estimation of population size from point counts.","language":"English","publisher":"American Ornithological Society","doi":"10.1525/auk.2009.07197","usgsCitation":"Efford, M.G., and Dawson, D.K., 2009, Effect of distance-related heterogeneity on population size estimates from point counts: The Auk, v. 126, no. 1, p. 100-111, https://doi.org/10.1525/auk.2009.07197.","productDescription":"12 p.","startPage":"100","endPage":"111","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":476007,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/auk.2009.07197","text":"Publisher Index Page"},{"id":202124,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"126","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db6257c1","contributors":{"authors":[{"text":"Efford, Murray G.","contributorId":91616,"corporation":false,"usgs":true,"family":"Efford","given":"Murray","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":343272,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dawson, Deanna K. ddawson@usgs.gov","contributorId":1257,"corporation":false,"usgs":true,"family":"Dawson","given":"Deanna","email":"ddawson@usgs.gov","middleInitial":"K.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":343273,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Protective guidelines have been based mainly on captive-breeding studies with chickens (Gallus gallus), mallards (Anas platyrhynchos), and ring-necked pheasants (Phasianus colchicus) or on field studies where whole eggs were collected and analyzed and the effects of the mercury were measured based on the reproductive success of the remaining eggs.  However, both of these methods have limitations.  As an alternative, we developed a technique that involves extracting a small sample of albumen from a live egg, sealing the egg, returning the egg to its nest to be naturally incubated by the parents, and then relating the hatching success of this microsampled egg to its mercury concentration.  After first developing this technique in the laboratory using chicken and mallard eggs, we selected the laughing gull (Larus atricilla) and black-necked stilt (Himantopus mexicanus) as test subjects in the field. We found that 92% of the microsampled laughing gull eggs met our reproductive endpoint of survival to the beginning of hatching compared to 100% for the paired control eggs within the same nests.  Microsampled black-necked stilt eggs exhibited 100% hatching success compared to 93% for the paired control eggs.  Our results indicate that microsampling is an effective tool for nonlethally sampling mercury concentrations in eggs and, as such, can be used for monitoring sensitive species, as well as for improving studies that examine the effects of mercury on avian reproduction.","language":"English","publisher":"Wiley","doi":"10.1897/08-316.1","usgsCitation":"Stebbins, K.R., Klimstra, J.D., Eagles-Smith C.A., Ackerman, J., and Heinz, G., 2009, A nonlethal microsampling technique to monitor the effects of mercury on wild bird eggs: Environmental Toxicology and Chemistry, v. 28, no. 3, p. 465-470, https://doi.org/10.1897/08-316.1.","productDescription":"6 p.","startPage":"465","endPage":"470","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":202571,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-03-01","publicationStatus":"PW","scienceBaseUri":"4f4e4b20e4b07f02db6ab9a5","contributors":{"authors":[{"text":"Stebbins, Katherine R.","contributorId":94012,"corporation":false,"usgs":true,"family":"Stebbins","given":"Katherine","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":343254,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klimstra, Jon D.","contributorId":6985,"corporation":false,"usgs":false,"family":"Klimstra","given":"Jon","email":"","middleInitial":"D.","affiliations":[{"id":6661,"text":"US Fish and Wildlife Service","active":true,"usgs":false}],"preferred":false,"id":343255,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Eagles-Smith C.A.","contributorId":128008,"corporation":true,"usgs":false,"organization":"Eagles-Smith C.A.","id":535070,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ackerman, Joshua T. 0000-0002-3074-8322 jackerman@usgs.gov","orcid":"https://orcid.org/0000-0002-3074-8322","contributorId":147078,"corporation":false,"usgs":true,"family":"Ackerman","given":"Joshua T.","email":"jackerman@usgs.gov","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":343256,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Heinz, Gary gheinz@usgs.gov","contributorId":3049,"corporation":false,"usgs":true,"family":"Heinz","given":"Gary","email":"gheinz@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":343257,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Its millions of wetlands and abundant ecosystem goods and services are highly sensitive to wide variations of temperature and precipitation in time and space characteristic of a strongly continental climate. Precipitation and temperature gradients across the PPR are orthogonal to each other. Precipitation nearly triples from west to east from approximately 300 mm/year to 900 mm/year, while mean annual temperature ranges from approximately 1&deg;C in the north to nearly 10&deg;C in the south. Twentieth-century weather records for 18 PPR weather stations representing 6 ecoregions revealed several trends. The climate generally has been getting warmer and wetter and the diurnal temperature range has decreased. Minimum daily temperatures warmed by 1.0&deg;C, while maximum daily temperatures cooled by 0.15&deg;C. Minimum temperature warmed more in winter than in summer, while maximum temperature cooled in summer and warmed in winter. Average annual precipitation increased by 49 mm or 9%. Palmer Drought Severity Index (PDSI) trends reflected increasing moisture availability for most weather stations; however, several stations in the western Canadian Prairies recorded effectively drier conditions. The east-west moisture gradient steepened during the twentieth century with stations in the west becoming drier and stations in the east becoming wetter. If the moisture gradient continues to steepen, the area of productive wetland ecosystems will shrink. Consequences for wetlands would be especially severe if the future climate does not provide supplemental moisture to offset higher evaporative demand.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Climatic Change","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10584-008-9543-5","collaboration":"7065_Millett.pdf","usgsCitation":"Millett, B., Johnson, W., and Guntenspergen, G., 2009, Climate trends of the North American prairie pothole region 1906-2000: Climatic Change, v. 93, no. 1-2, p. 243-267, https://doi.org/10.1007/s10584-008-9543-5.","productDescription":"243-267","startPage":"243","endPage":"267","numberOfPages":"25","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16977,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1007/s10584-008-9543-5","linkFileType":{"id":5,"text":"html"}},{"id":202229,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"93","issue":"1-2","noUsgsAuthors":false,"publicationDate":"2009-02-19","publicationStatus":"PW","scienceBaseUri":"4f4e4a51e4b07f02db62a07d","contributors":{"authors":[{"text":"Millett, B.","contributorId":40709,"corporation":false,"usgs":true,"family":"Millett","given":"B.","email":"","affiliations":[],"preferred":false,"id":343221,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, W.C.","contributorId":68003,"corporation":false,"usgs":true,"family":"Johnson","given":"W.C.","email":"","affiliations":[],"preferred":false,"id":343222,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guntenspergen, G.","contributorId":88305,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"G.","email":"","affiliations":[],"preferred":false,"id":343223,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The holotypes of these species were deposited and placed on public exhibit in the Philadelphia Museum, the predominant North American systematic collection of the early nineteenth century.  Like most private museums of that era, the Philadelphia Museum eventually went out of business, and its collections were dispersed and, for the most part, lost.  Fortunately, Titian R. Peale made a detailed field sketch of the two specimens soon after their capture and subsequently executed a watercolor based on that sketch.

Illustrations of holotypes are taxonomically useful when they depict diagnostic characters of species.  They take on added taxonomic significance in the absence of the holotypes.

Reducing the bias and variance of estimates of population parameters reduces uncertainty in population status and projections, thereby reducing the overall uncertainty under which a population manager must make a decision. In capture-recapture studies, imperfect detection of individuals, unobservable life-history states, local movement outside study areas, and tag loss can cause bias or precision problems with estimates of population parameters. Furthermore, excessive disturbance to individuals during capture?recapture sampling may be of concern because disturbance may have demographic consequences. We address these problems using as an example a monitoring program for Black-footed Albatross (Phoebastria nigripes) and Laysan Albatross (Phoebastria immutabilis) nesting populations in the northwestern Hawaiian Islands. To mitigate these estimation problems, we describe a synergistic combination of sampling design and modeling approaches. Solutions include multiple capture periods per season and multistate, robust design statistical models, dead recoveries and incidental observations, telemetry and data loggers, buffer areas around study plots to neutralize the effect of local movements outside study plots, and double banding and statistical models that account for band loss. We also present a variation on the robust capture?recapture design and a corresponding statistical model that minimizes disturbance to individuals. For the albatross case study, this less invasive robust design was more time efficient and, when used in combination with a traditional robust design, reduced the standard error of detection probability by 14% with only two hours of additional effort in the field. These field techniques and associated modeling approaches are applicable to studies of most taxa being marked and in some cases have individually been applied to studies of birds, fish, herpetofauna, and mammals.</p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/07-1072.1","usgsCitation":"Kendall, W.L., Converse, S.J., Doherty, P.F., Naughton, M.B., Anders, A., Hines, J., and Flint, E., 2009, Sampling design considerations for demographic studies: a case of colonial seabirds: Ecological Applications, v. 19, no. 1, p. 55-68, https://doi.org/10.1890/07-1072.1.","productDescription":"14 p.","startPage":"55","endPage":"68","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202098,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a03e4b07f02db5f8305","contributors":{"authors":[{"text":"Kendall, William L. wkendall@usgs.gov","contributorId":406,"corporation":false,"usgs":true,"family":"Kendall","given":"William","email":"wkendall@usgs.gov","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343241,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Converse, Sarah J. 0000-0002-3719-5441 sconverse@usgs.gov","orcid":"https://orcid.org/0000-0002-3719-5441","contributorId":3513,"corporation":false,"usgs":true,"family":"Converse","given":"Sarah","email":"sconverse@usgs.gov","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343243,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Doherty, Paul F.

Georgia?s Bobwhite Quail Initiative (BQI) is a competitive, proposal-based system that provides incentives to landowners to establish habitat for northern bobwhites (Colinus virginianus).  Using data from monitoring conducted in the program?s first years (1999?2001), we developed alternative hierarchical models to predict bobwhite abundance in response to program habitat modifications on local and regional scales.  Effects of habitat and habitat management on bobwhite population response varied among geographical scales, but high measurement variability rendered the specific nature of these scaled effects equivocal.  Under some models, BQI had positive impact at both local farm scales (1, 9 km2), particularly when practice acres were clustered, whereas other credible models indicated that bird response did not depend on spatial arrangement of practices.  Thus, uncertainty about landscape-level effects of management presents a challenge to program managers who must decide which proposals to accept.  We demonstrate that optimal selection decisions can be made despite this uncertainty and that uncertainty can be reduced over time, with consequent improvement in management efficacy.  However, such an adaptive approach to BQI program implementation would require the reestablishment of monitoring of bobwhite abundance, an effort for which funding was discontinued in 2002.  For landscape-level conservation programs generally, our approach demonstrates the value in assessing multiple scales of impact of habitat modification programs, and it reveals the utility of addressing management uncertainty through multiple decision models and system monitoring.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Landscape Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10980-008-9320-x","collaboration":"7062_Howell.pdf","usgsCitation":"Howell, J., Moore, C., Conroy, M., Hamrick, R., Cooper, R., Thackston, R., and Carroll, J., 2009, Conservation of northern bobwhite on private lands in Georgia, USA under uncertainty about landscape-level habitat effects: Landscape Ecology, v. 24, no. 3, p. 405-418, https://doi.org/10.1007/s10980-008-9320-x.","productDescription":"405-418","startPage":"405","endPage":"418","numberOfPages":"14","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16974,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1007/s10980-008-9320-x","linkFileType":{"id":5,"text":"html"}},{"id":197284,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-02-07","publicationStatus":"PW","scienceBaseUri":"4f4e4b00e4b07f02db69840b","contributors":{"authors":[{"text":"Howell, J.E.","contributorId":28694,"corporation":false,"usgs":true,"family":"Howell","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":332791,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, C.

Retention probabilities for standard aluminum leg bands were high (estimate of 0.9995, SE = 0.001) and constant over 1-40 months.   In contrast, apparent retention probabilities for reward bands demonstrated an interactive relationship between 5 size and species classes (small cackling, medium Canada, large Canada, snow, and Ross?s geese).  In addition, apparent retention probabilities for each of the 5 classes varied quadratically with time, being lower immediately after banding and at older age classes.

We have compiled 56 measurements of above-ground annual productivity for Spartina alterniflora, the dominant macrophyte in North American coastal wetlands.  Our compilation indicates a significant latitudinal gradient in productivity, which we interpret to be determined primarily by temperature and/or the length of growing season.  Simple linear regression yields a 27 g m-2 yr -1 increase in productivity with an increase of mean annual temperature by one degree C.  If temperatures warm 2?4 C over the next century, then marsh productivity may increase by 10?40%, though physiological research suggests that increases in the north could potentially be offset by some decreases in the south.  This increase in productivity is roughly equivalent to estimates of marsh lost due to future sea level change.  If a warming-induced stimulation of vegetation growth will enhance vertical accretion and limit erosion, then the combined effects of global change may be to increase the total productivity and ecosystem services of tidal wetlands, at least in Northern latitudes.","largerWorkType":{"id":2,"text":"Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2486.2008.01834.x","usgsCitation":"Kirwan, M., Guntenspergen, G.R., and Morris, J.T., 2009, Latitudinal trends in <i>Spartina alterniflora</i> productivity and the response of coastal marshes to global change: Global Change Biology, v. 15, no. 8, p. 1982-1989, https://doi.org/10.1111/j.1365-2486.2008.01834.x.","productDescription":"8 p.","startPage":"1982","endPage":"1989","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202127,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"8","noUsgsAuthors":false,"publicationDate":"2009-07-02","publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a89ef","contributors":{"authors":[{"text":"Kirwan, Matthew L. 0000-0002-0658-3038","orcid":"https://orcid.org/0000-0002-0658-3038","contributorId":84060,"corporation":false,"usgs":true,"family":"Kirwan","given":"Matthew L.","affiliations":[],"preferred":false,"id":343175,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guntenspergen, Glenn R. 0000-0002-8593-0244 glenn_guntenspergen@usgs.gov","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":2885,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"Glenn","email":"glenn_guntenspergen@usgs.gov","middleInitial":"R.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":343176,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Morris, James T.","contributorId":29118,"corporation":false,"usgs":true,"family":"Morris","given":"James","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":343174,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Transition from agriculture to residential land and water use necessitates additional understanding of water resources. The ground-water basin is conceptualized as a single interconnected hydrologic system consisting of the consolidated-rock mountains and adjoining unconsolidated basin-fill valleys. Within the basin fill, unconfined conditions exist along the valley margins and confined conditions exist in the central areas of the valleys. Transmissivity of the unconsolidated basin-fill aquifer ranges from 1,000 to 270,000 square feet per day. Within the consolidated rock of the mountains, ground-water flow largely is unconfined, though variability in geologic structure, stratigraphy, and lithology has created some areas where ground-water flow is confined. Hydraulic conductivity of the consolidated rock ranges from 0.003 to 100 feet per day.\r\n\r\nGround water within the basin generally moves from the mountains toward the central and northern areas of Tooele Valley. Steep hydraulic gradients exist at Tooele Army Depot and near Erda. The estimated average annual ground-water recharge within the basin is 82,000 acre-feet per year. The primary source of recharge is precipitation in the mountains; other sources of recharge are irrigation water and streams. Recharge from precipitation was determined using the Basin Characterization Model. Estimated average annual ground-water discharge within the basin is 84,000 acre-feet per year. Discharge is to wells, springs, and drains, and by evapotranspiration. Water levels at wells within the basin indicate periods of increased recharge during 1983-84 and 1996-2000. During these periods annual precipitation at Tooele City exceeded the 1971-2000 annual average for consecutive years.\r\n\r\nThe water with the lowest dissolved-solids concentrations exists in the mountain areas where most of the ground-water recharge occurs. The principal dissolved constituents are calcium and bicarbonate. Dissolved-solids concentration increases in the central and northern parts of Tooele Valley, at the distal ends of the ground-water flow paths. Increased concentration is due mainly to greater amounts of sodium and chloride. Deuterium and oxygen-18 values indicate water recharged primarily from precipitation occurs throughout the ground-water basin. Ground water with the highest percentage of recharge from irrigation exists along the eastern margin of Tooele Valley, indicating negligible recharge from the adjacent consolidated rock. Tritium and tritiogenic helium-3 concentrations indicate modern water exists along the flow paths originating in the Oquirrh Mountains between Settlement and Pass Canyons and extending between the steep hydraulic gradient areas at Tooele Army Depot and Erda. Pre-modern water exists in areas east of Erda and near Stansbury Park. Using the change in tritium along the flow paths originating in the Oquirrh Mountains, a first-order estimate of average linear ground-water velocity for the general area is roughly 2 to 5 feet per day.\r\n\r\nA numerical ground-water flow model was developed to simulate ground-water flow in the Tooele Valley ground-water basin and to test the conceptual understanding of the ground-water system. Simulating flow in consolidated rock allows recharge and withdrawal from wells in or near consolidated rock to be simulated more accurately. In general, the model accurately simulates water levels and water-level fluctuations and can be considered an adequate tool to help determine the valley-wide effects on water levels of additional ground-water withdrawal and changes in water use. The simulated increase in storage during a projection simulation using 2003 withdrawal rates and average recharge indicates that repeated years of average precipitation and recharge conditions do not completely restore the system after multiple years of below-normal precipitation.

The datasets are made available for use as a management tool to research scientists and natural-resource managers. An innovative scanning lidar instrument originally developed by NASA, and known as the Airborne Topographic Mapper (ATM), was used during data acquisition. The ATM system is a scanning lidar system that measures high-resolution topography of the land surface and incorporates a green-wavelength laser operating at pulse rates of 2 to 10 kilohertz. Measurements from the laser-ranging device are coupled with data acquired from inertial navigation system (INS) attitude sensors and differentially corrected global positioning system (GPS) receivers to measure topography of the surface at accuracies of +/-15 centimeters. The nominal ATM platform is a Twin Otter or P-3 Orion aircraft, but the instrument may be deployed on a range of light aircraft.\r\n\r\nElevation measurements were collected over the survey area using the ATM system, and the resulting data were then processed using the Airborne Lidar Processing System (ALPS), a custom-built processing system developed in a NASA-USGS collaboration. ALPS supports the exploration and processing of lidar data in an interactive or batch mode.

The datasets are made available for use as a management tool to research scientists and natural-resource managers. An innovative scanning lidar instrument originally developed by NASA, and known as the Airborne Topographic Mapper (ATM), was used during data acquisition. The ATM system is a scanning lidar system that measures high-resolution topography of the land surface and incorporates a green-wavelength laser operating at pulse rates of 2 to 10 kilohertz. Measurements from the laser-ranging device are coupled with data acquired from inertial navigation system (INS) attitude sensors and differentially corrected global positioning system (GPS) receivers to measure topography of the surface at accuracies of +/-15 centimeters. The nominal ATM platform is a Twin Otter or P-3 Orion aircraft, but the instrument may be deployed on a range of light aircraft.\r\n\r\nElevation measurements were collected over the survey area using the ATM system, and the resulting data were then processed using the Airborne Lidar Processing System (ALPS), a custom-built processing system developed in a NASA-USGS collaboration. ALPS supports the exploration and processing of lidar data in an interactive or batch mode. Modules for presurvey flight-line definition, flight-path plotting, lidar raster and waveform investigation, and digital camera image playback have been developed. Processing algorithms have been developed to extract the range to the first and last significant return within each waveform. ALPS is used routinely to create maps that represent submerged or first-surface topography.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ds448","usgsCitation":"Klipp, E.S., Nayegandhi, A., Brock, J., Sallenger, A., Bonisteel, J.M., Yates, X., and Wright, C.W., 2009, ATM Coastal Topography-Texas, 2001: UTM Zone 14: U.S. Geological Survey Data Series 448, HTML Document; DVD, https://doi.org/10.3133/ds448.","productDescription":"HTML Document; DVD","onlineOnly":"N","additionalOnlineFiles":"Y","costCenters":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true},{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":423299,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_97205.htm","linkFileType":{"id":5,"text":"html"}},{"id":13501,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/ds/448/","linkFileType":{"id":5,"text":"html"}},{"id":197381,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Texas","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -97.1511,\n              28.5933\n            ],\n            [\n              -97.1511,\n              27.715\n            ],\n            [\n              -96,\n              27.715\n            ],\n            [\n              -96,\n              28.5933\n            ],\n            [\n              -97.1511,\n              28.5933\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b14e4b07f02db6a4774","contributors":{"authors":[{"text":"Klipp, Emily S. eklipp@usgs.gov","contributorId":2754,"corporation":false,"usgs":true,"family":"Klipp","given":"Emily","email":"eklipp@usgs.gov","middleInitial":"S.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":304788,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nayegandhi, Amar","contributorId":37292,"corporation":false,"usgs":true,"family":"Nayegandhi","given":"Amar","affiliations":[],"preferred":false,"id":304790,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brock, John 0000-0002-5289-9332 jbrock@usgs.gov","orcid":"https://orcid.org/0000-0002-5289-9332","contributorId":2261,"corporation":false,"usgs":true,"family":"Brock","given":"John","email":"jbrock@usgs.gov","affiliations":[{"id":5061,"text":"National Cooperative Geologic Mapping and Landslide Hazards","active":true,"usgs":true}],"preferred":true,"id":304787,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sallenger, A.
