Factor analysis of 195 established campsites on eight impact indicator variables revealed three dimensions of campsite impact: area disturbance, soil and groundcover damage, and tree-related damage.  Four distinctive backcountry campsite types were identified, three of which were derived from cluster analyses of factor scores.  These four backcountry campsite types characterize the intensity and areal extent of resource impacts, and they vary in locational and environmental attributes.  At an aggregate level, different campsite types contributed unequally to the cumulative level of impact.  The dimensional structure and typology developed in this study demonstrates that campsite impacts can be viewed and examined holistically with the use of multivariate methods.

On each plot, marsh fiddler crab (Uca pugnax) populations were monitored by repeatedly counting the number of burrow holes in 2 counting areas marked out along tidal guts.  One half of each counting area was covered with bird netting to evaluate sublethal toxic effects, which, if present, could result in increased susceptibility to bird predation. A statistically significant linear association was established between the number of holes and the number of crabs.  No significant differences were found in the numbers of holes (or crabs) in the sprayed vs. control plots and in the covered vs. uncovered sections.  However, survival of juvenile crabs in in situ bioassays was significantly reduced (16% lower) by the spraying.  Median acetylcholinesterase activity in claw muscle of red-jointed fiddler crabs (U. minax) collected 2 days after an operational spray with Abate 4E was significantly reduced (28% lower) compared to unsprayed crabs.  In view of the toxicity to juvenile crabs and the cholinesterase inhibition, we recommend continued monitoring and research for non-target impacts of Abate 4E on fiddler crabs to establish whether the reported level of cholinesterase inhibition results in acute or chronic toxicity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Mosquito Control Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Pinkney, A., McGowan, P.C., Murphy, D., Lowe, T., Sparling, D.W., and Meredith, W., 1999, Effects of temephos (Abate? 4E) on fiddler crabs (Uca pugnax and Uca minax) on a Delaware salt marsh: Journal of the American Mosquito Control Association, v. 15, no. 3, p. 321-329.","productDescription":"321-329","startPage":"321","endPage":"329","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202018,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a27e4b07f02db6107f6","contributors":{"authors":[{"text":"Pinkney, A.E.","contributorId":87501,"corporation":false,"usgs":true,"family":"Pinkney","given":"A.E.","affiliations":[],"preferred":false,"id":339904,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McGowan, P.

Robust estimation of these transitions using multiple observations of individually identifiable marked individuals has received considerable attention in recent years.  However, in some situations, individuals are not identifiable (or have a very low recapture rate), although all individuals in a sample can be assigned to a particular state (e.g. breeding or non-breeding) without error.  In such cases, only aggregate data (number of individuals in a given state at each occasion) are available.  If the underlying matrix of transition probabilities does not vary through time and aggregate data are available for several time periods, then it is possible to estimate these parameters using least-squares methods.  Even when such data are available, this assumption of stationarity will usually be deemed overly restrictive and, frequently, data will only be available for two time periods.  In these cases, the problem reduces to estimating the most likely matrix (or matrices) leading to the observed frequency distribution of individuals in each state.  An entropy maximization approach has been previously suggested.  In this paper, we show that the entropy approach rests on a particular limiting assumption, and does not provide estimates of latent population parameters (the transition probabilities), but rather predictions of realized rates.","language":"English","publisher":"Taylor & Francis","doi":"10.1080/00063659909477232","usgsCitation":"Cooch, E., and Link, W., 1999, Estimating transition probabilities in unmarked populations: Entropy revisited: Bird Study, v. 46, no.

The need to contain visitor impacts within acceptable limits has prompted park and protected area managers to implement a wide variety of strategies and actions, many of which are spatial in nature. This paper classifies and illustrates the basic spatial strategies for managing visitor impacts in parks and protected areas.      A typology of four spatial strategies was proposed based on the recreation and park management literature.  Spatial segregation is a common strategy for shielding sensitive resources from visitor impacts or for separating potentially conflicting types of use.  Two forms of spatial segregation are zoning and closure.  A spatial containment strategy is intended to minimize the aggregate extent of visitor impacts by confining use to limited designated or established Iocations.   In contrast, a spatial dispersal strategy seeks to spread visitor use, reducing the frequency of use to levels that avoid or minimize permanent resource impacts or visitor crowding and conflict.  Finally, a spatial configuration strategy minimizes impacting visitor behavior though the judicious spatial arrangement of facilities.  These four spatial strategics can be implemented separately or in combination at varying spatial scales within a single park.      A survey of national park managers provides an empirical example of the diversity of implemented spatial strategies in managing visitor impacts.  Spatial segregation is frequently applied in the form of camping restrictions or closures to protect sensitive natural or cultural  resources and to separate incompatible visitor activities.  Spatial containment is the most widely applied strategy for minimizing the areal extent of resource impacts.  Spatial dispersal is commonly applied to reduce visitor crowding or conflicts in popular destination areas but is less frequently applied or effective in minimizing resource impacts.  Spatial configuration was only minimally evaluated, as it was not included in the survey.      The proposed typology of spatial strategies offers a useful means of organizing and understanding the wide variety of management strategies and actions applied in managing visitor impacts in parks and protected areas.  Examples from U.S. national  parks demonstrate the diversity of these basic strategies and their flexibility in implementation at various spatial scales. Documentation of these examples helps illustrate their application and inform managers of the multitude of options.  Further analysis from the spatial perspective is needed Io extend the applicability of this typology to other recreational activities and management issues.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Park and Recreation Administration","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"5511_Leung.pdf","usgsCitation":"Leung, Y., and Marion, J., 1999, Spatial strategies for managing visitor impacts in National Parks: Journal of Park and Recreation Administration, v. 17, no. 4, p. 20-38.","productDescription":"20-38","startPage":"20","endPage":"38","numberOfPages":"19","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200205,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269476,"type":{"id":11,"text":"Document"},"url":"https://js.sagamorepub.com/jpra/article/view/1626"}],"volume":"17","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e478fe4b07f02db48a1e3","contributors":{"authors":[{"text":"Leung, Y.-F.","contributorId":34613,"corporation":false,"usgs":true,"family":"Leung","given":"Y.-F.","email":"","affiliations":[],"preferred":false,"id":340022,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Marion, J.

We measured the vocal responses and movements of radio-tagged black rails (Laterallus jamaicensis; 26 M, 17 F) to playback of vocalizations at 2 sites in Florida during the breeding seasons of 1992-95.  We used coefficients from logistic regression equations to model probability of a response conditional to the birds' sex. nesting status, distance to playback source, and time of survey.  With a probability of 0.811, nonnesting male black rails were ))lost likely to respond to playback, while nesting females were the least likely to respond (probability = 0.189).  We used linear regression to determine daily, monthly and annual variation in response from weekly playback surveys along a fixed route during the breeding seasons of 1993-95.  Significant sources of variation in the regression model were month (F3.48 = 3.89, P = 0.014), year (F2.48 = 9.37, P < 0.001), temperature (F1.48 = 5.44, P = 0.024), and month X year (F5.48 = 2.69, P = 0.031).  The model was highly significant (P < 0.001) and explained 54% of the variation of mean response per survey period (r2 = 0.54).  We combined response probability data from radiotagged black rails with playback survey route data to provide a density estimate of 0.25 birds/ha for the St. Johns National Wildlife Refuge.  The relation between the number of black rails heard during playback surveys to the actual number present was influenced by a number of variables.

The predominant tree species with cavities were red maple (Acer rubrum; 39%) and aspen (Populus sp.; 31%); 72% of all trees with cavities were alive.  Density ees/plot averaged from 1.0 +0.4 (x +SE) in wetland softwoods to 1.9 +0.4 in upland hardwoods.  This low density of potential cavity trees and the small mean dbh (39.4 +1.6 cm) indicate a young forest with few suitable cavities.

An understanding of the reference condition requires knowledge of dominant factors influencing ecosystem processes and biological communities.  In this paper, we focus on  natural physical factors (conditions and processes) that drive coastal wetland ecosystems of the Laurentian Great Lakes.  Great Lakes coastal wetlands develop under conditions of large-lake hydrology and disturbance imposed at a hierarchy of spatial and temporal scales and contain biotic communities adapted to unstable and unpredictable conditions.  Coastal wetlands are configured along a continuum of hydrogeomorphic types: open coastal wetlands, drowned river mouth and flooded delta wetlands, and protected wetlands, each developing distinct ecosystem properties and biotic communities. Hydrogeomorphic factors associated with the lake and watershed operate at a hierarchy of scales: a) local and short-term (seiches and ice action), b) watershed / lakewide / annual (seasonal water- level change), and c) larger or year-to-year and longer ( regional and/or greater than one-year).  Other physical factors include the unique water quality features of each lake.  The aim of this paper is to provide scientists and managers with a framework for considering regional and site-specific geomorphometry and a hierarchy of physical processes in planning management and conservation projects.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Robbins, C., 1999, Fifty-eighth Christmas Bird Count. 166.

In this paper we investigated the degree to which species density varies with location within the landscape, independent of contemporaneous environmental conditions.  The area studied was a coastal marsh landscape subject to periodic storm events.  To evaluate the impact of historical effects, it was assumed that the landscape position of a plot relative to the river's mouth ('distance from sea') and to the edge of a stream channel ('distance from shore') would correlate with the impact of prior storm events, an assumption supported by previous studies.  To evaluate the importance of spatial location on species density, data were collected from five sites located at increasing distances from the river's mouth along the Middle Pearl River in Louisiana.  At each site, plots were established systematically along transects perpendicular to the shoreline.  For each of the 175 Plots, we measured elevation, soil salinity, percent of plot recently disturbed, percent of sunlight captured by the plant canopy (as a measure of plant abundance), and plant species density.  Structural equation analysis ascertained the degree to which landscape position variables explained variation in species density that could not be explained by current environmental indicators.  Without considering landscape variables, 54% of the variation in species density could be explained by the effects of salinity, flooding, and plant abundance.  When landscape variables were included, distance from shore was unimportant but distance from sea explained an additional 12% of the variance in species density (R2 of final model = 66%).  Based on these results it appears that at least some of the otherwise unexplained variation in species density can be attributed to landscape position, and presumably previous storm events.  We suggest that future studies may gain additional insight into the factors controlling current patterns of species density by examining the effects of position within the landscape.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecoscience","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1080/11956860.1999.11682536","usgsCitation":"Grace, J., and Guntenspergen, G., 1999, The effects of landscape position on plant species density:  Evidence of past environmental effects in a coastal wetland: Écoscience, v. 6, no. 3, p. 381-391, https://doi.org/10.1080/11956860.1999.11682536.","productDescription":"381-391","startPage":"381","endPage":"391","numberOfPages":"11","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200274,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationDate":"2016-03-24","publicationStatus":"PW","scienceBaseUri":"4f4e4a9be4b07f02db65deca","contributors":{"authors":[{"text":"Grace, J.B. 0000-0001-6374-4726","orcid":"https://orcid.org/0000-0001-6374-4726","contributorId":38938,"corporation":false,"usgs":true,"family":"Grace","given":"J.B.","affiliations":[],"preferred":false,"id":339869,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guntenspergen, G.R. 0000-0002-8593-0244","orcid":"https://orcid.org/0000-0002-8593-0244","contributorId":95424,"corporation":false,"usgs":true,"family":"Guntenspergen","given":"G.R.","affiliations":[],"preferred":false,"id":339870,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Operation Recovery, which linked numerous ringing stations along the east coast in a study of autumn migration of passerines, and the Preseason Duck Ringing Programme in prairie states and provinces, conclusively demonstrated the feasibility of large-scale projects.  The subsequent development of powerful analytical models and computing capabilities expanded the quantitative potential for further large-scale projects.  Monitoring Avian Productivity and Survivorship, and Adaptive Harvest Management are current examples of truly large-scale programmes.  Their exemplary success and the availability of versatile analytical tools are driving changes in the North American bird ringing programme.  Both the US and Canadian ringing offices are modifying operations to collect more and better data to facilitate large-scale studies and promote a more project-oriented ringing programme.  New large-scale programmes such as the Cornell Nest Box Network are on the horizon.","language":"English","publisher":"Taylor & Francis","doi":"10.1080/00063659909477254","usgsCitation":"Tautin, J., Metras, L., and Smith, G.W., 1999, Large-scale studies of marked birds in North America: Bird Study, v. 46, no.

The species were collected in all possible pairwise combinations of sympatry, including the first record of such documented for S. arizonae and S. mascotensis.  Emphasis is devoted to the discrimination of S. arizonae and S. mascotensis, from each other and from typical S. hispidus, using qualitative features of the skin and skull and morphometric analyses of craniodental measurements.  Based on these results and examination of type specimens, additional synonyms of S. mascotensis are identified, with reassignment of two forms, tonalensis Bailey (1902) and obvelatus Russell (1952), currently mistaken as subspecies of S. hispidus.  Sigmodon mascotensis emerges as a species distributed from southern Nayarit and Zacatecas to extreme western Chiapas, where it inhabits deciduous or semi-deciduous tropical vegetation having a pronounced dry season.  These reallocations and other reidentifications remove any documentation for S. hispidus along the entire Pacific versant of Mexico.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Biological Society of Washington","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Carleton, M., Fisher, R., and Gardner, A.L., 1999, Identification and distribution of cotton rats, genus Sigmodon (Muridae: Sigmodontinae), of Nayarit, M?xico: Proceedings of the Biological Society of Washington, v. 112, no. 4, p. 813-856.","productDescription":"813-856","startPage":"813","endPage":"856","numberOfPages":"44","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":199523,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"112","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5faaf1","contributors":{"authors":[{"text":"Carleton, M.D.","contributorId":106597,"corporation":false,"usgs":true,"family":"Carleton","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":339784,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fisher, R.D.","contributorId":62967,"corporation":false,"usgs":true,"family":"Fisher","given":"R.D.","email":"","affiliations":[],"preferred":false,"id":339782,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gardner, A.

We applied this methodology to a data set of 4184 serins (Serinus serinus) trapped in northeastern Spain during 1985-96, in order to investigate age-, sex-, and time-specific variation in survival rates.  Using this approach, we were able to successfully incorporate the majority of ringings of serins.  Had we eliminated birds not previously captured (as has been advocated to avoid the problem of transience) we would have reduced our sample sizes by >2000 releases.  In addition, we were able to include 1610 releases of birds of unknown (but predicted) sex; these data contributed to the precision of our estimates and the power of statistical tests.  We discuss problems with data structure, encoding of the algorithms to compute parameter estimates, model selection, identifiability of parameters, and goodness-of-fit, and make recommendations for the design and analysis of future studies facing similar problems.","language":"English","publisher":"Taylor & Francis","doi":"10.1080/00063659909477233","usgsCitation":"Conroy, M., Senar, J., Hines, J., and Domenech, J., 1999, Development and application of a mark-recapture model incorporating predicted sex and transitory behaviour: Bird Study, v. 46, no.

DeSante 1995). Examples include studies of habitat quality, population trends, life-history tactics, and metapopulation dynamics. From a demographic perspective, productivity is the number of young counted at a given time of year, produced per adult (e.g. Caswell 1989). Various measures have been used to estimate productivity. One of the most attractive is mist netting during the summer after young have left the nest, but ideally before they have left the study area. Several programs use this approach, including the Constant Effort Sites Scheme of the British Trust for Ornithology (Baillie et al. 1986, Bibby et al. 1992) and the Monitoring Avian Productivity and Survivorship (MAPS) program (DeSante et al. 1993) in North America.</p><p>Hatching-year (HY) and after-hatching-year (AHY) birds are widely believed to have different susceptibilities to netting (DeSante et al. 1995, Peach et al. 1996), so the ratio of HY's to AHY's obtained from netting is not used as an estimate of productivity. Instead, investigators hope that the relative susceptibility to capture is about the same among the samples being compared so that the age ratios in mistnet samples provide a reliable index to productivity (DeSante 1995, DeSante et al. 1995).</p>","language":"English","publisher":"American Ornithological Society","doi":"10.2307/4089698","usgsCitation":"Bart, J., Kepler, C., Sykes, P., and Bocetti, C.I., 1999, Evaluation of mist-net sampling as an index to productivity in Kirtland's Warblers: The Auk, v. 116, no. 4, p. 1147-1151, https://doi.org/10.2307/4089698.","productDescription":"5 p.","startPage":"1147","endPage":"1151","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":199587,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"116","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e499fe4b07f02db5bcd0f","contributors":{"authors":[{"text":"Bart, J.","contributorId":76272,"corporation":false,"usgs":true,"family":"Bart","given":"J.","affiliations":[],"preferred":false,"id":339778,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kepler, C.","contributorId":77627,"corporation":false,"usgs":true,"family":"Kepler","given":"C.","email":"","affiliations":[],"preferred":false,"id":339779,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sykes, P.","contributorId":35851,"corporation":false,"usgs":true,"family":"Sykes","given":"P.","affiliations":[],"preferred":false,"id":339776,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bocetti, Carol I.","contributorId":60343,"corporation":false,"usgs":true,"family":"Bocetti","given":"Carol","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":339777,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
