We present a combined analysis of data from two large-scale surveys of bird populations. The North American Breeding Bird Survey is conducted each summer; the Christmas Bird Count is conducted in early winter. The temporal staggering of these surveys allows investigation of seasonal components of population change, which we illustrate with an examination of the effects of severe winters on the Carolina Wren (Thryothorus ludovicianus). Our analysis uses a hierarchical log-linear model with controls for survey-specific sampling covariates. Temporal change in population size is modeled seasonally, with covariates for winter severity. Overall, the winter-spring seasons are associated with 82% of the total population variation for Carolina Wrens, and an additional day of snow cover during winter-spring is associated with an incremental decline of 1.1% of the population.

Recent conservation management has emphasized the conversion of cultivated farmland and degraded pastures to intact grassland to improve upland nesting habitat. The consequences of changes in land-use cover that alter watershed processes have not been evaluated relative to their effect on the water budgets and vegetation dynamics of associated wetlands. We simulated the effect of upland agricultural practices on the water budget and vegetation of a semipermanent prairie wetland by modifying a previously published mathematical model (WETSIM). Watershed cover/land-use practices were categorized as unmanaged grassland (native grass, smooth brome), managed grassland (moderately heavily grazed, prescribed burned), cultivated crops (row crop, small grain), and alfalfa hayland. Model simulations showed that differing rates of evapotranspiration and runoff associated with different upland plant-cover categories in the surrounding catchment produced differences in wetland water budgets and linked ecological dynamics. Wetland water levels were highest and vegetation the most dynamic under the managed-grassland simulations, while water levels were the lowest and vegetation the least dynamic under the unmanaged-grassland simulations. The modeling results suggest that unmanaged grassland, often planted for waterfowl nesting, may produce the least favorable wetland conditions for birds, especially in drier regions of the Prairie Pothole Region. These results stand as hypotheses that urgently need to be verified with empirical data.","language":"English","publisher":"Wiley Online","doi":"10.1890/05-1195","usgsCitation":"Voldseth, R., Johnson, W., Gilmanov, T., Guntenspergen, G., and Millett, B., 2007, Model estimation of land-use effects on water levels of northern Prairie wetlands: Ecological Applications, v. 17, no. 2, p. 527-540, https://doi.org/10.1890/05-1195.","productDescription":"14 p.","startPage":"527","endPage":"540","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202770,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Iowa, Minnesota, Montana, Nebraska, North Dakota, South Dakota","otherGeospatial":"Prairie Pothole Region","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -116.54296874999999,\n 50.233151832472245\n ],\n [\n -108.896484375,\n 47.87214396888731\n ],\n [\n -104.94140625,\n 47.45780853075031\n ],\n [\n -102.39257812499999,\n 47.635783590864854\n ],\n [\n -101.162109375,\n 44.402391829093915\n ],\n [\n -99.40429687500001,\n 42.74701217318067\n ],\n [\n -95.88867187500001,\n 41.57436130598913\n ],\n [\n -95.625,\n 45.89000815866182\n ],\n [\n -95.888671875,\n 49.89463439573421\n ],\n [\n -111.884765625,\n 51.56341232867585\n ],\n [\n -116.54296874999999,\n 50.233151832472245\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"17","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699b3d","contributors":{"authors":[{"text":"Voldseth, R.A.","contributorId":80778,"corporation":false,"usgs":true,"family":"Voldseth","given":"R.A.","affiliations":[],"preferred":false,"id":342683,"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":342681,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gilmanov, T.","contributorId":72892,"corporation":false,"usgs":true,"family":"Gilmanov","given":"T.","email":"","affiliations":[],"preferred":false,"id":342682,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"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":342684,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Millett, B.V.","contributorId":48274,"corporation":false,"usgs":true,"family":"Millett","given":"B.V.","email":"","affiliations":[],"preferred":false,"id":342680,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":5224717,"text":"5224717 - 2007 - Minimising visitor impacts to protected areas: The efficacy of low impact education programmes","interactions":[],"lastModifiedDate":"2021-06-04T16:34:54.998312","indexId":"5224717","displayToPublicDate":"2010-06-16T12:18:32","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2472,"text":"Journal of Sustainable Tourism","active":true,"publicationSubtype":{"id":10}},"title":"Minimising visitor impacts to protected areas: The efficacy of low impact education programmes","docAbstract":"Protected area managers, tourism providers, and other organisations commonly employ education programmes to address visitation-related impairment of natural and cultural resources, social conditions, and neighbouring communities.

Contaminants may also impact reproductive output or other aspects of life history through effects on resource acquisition or allocation. We fed successfully breeding female white-footed mice (Peromyscus leucopus) diets containing polychlorinated biphenyls (2:1 Aroclor 1242:1254) at levels of 0 (n = 10), 10 (n = 12), and 25 (n = 10) ppm (mg polychlorinated biphenyls [PCBs]/kg food). After 4 months on the diets, female mice were bred with male mice maintained on control food. There was no effect of PCB exposure on litter size at birth or weaning, although fewer female mice on the 25-ppm diet gave birth. There was no effect of PCB dose on maternal metabolic rate at peak lactation or on total food (dry matter) intake during lactation. Female mice on the 10-ppm diet, however, consumed more food per pup during lactation and weaned larger pups, although these differences disappeared after 4 weeks of age. We conclude that although moderate-term exposure to PCBs did decrease the number of litters produced for high-dose female mice, it did not change litter size, pup growth rate, or energetic measures for those female mice that did successfully reproduce.","language":"English","publisher":"Springer","doi":"10.1007/s00244-006-0045-z","usgsCitation":"Voltura, M., and French, J., 2007, Effects of dietary PCB exposure on reproduction in the white-footed mouse (Peromyscus leucopus): Archives of Environmental Contamination and Toxicology, v. 52, no. 2, p. 264-269, https://doi.org/10.1007/s00244-006-0045-z.","productDescription":"6 p.","startPage":"264","endPage":"269","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202296,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"2","noUsgsAuthors":false,"publicationDate":"2006-12-07","publicationStatus":"PW","scienceBaseUri":"4f4e4ae2e4b07f02db688cb0","contributors":{"authors":[{"text":"Voltura, M.B.","contributorId":53500,"corporation":false,"usgs":true,"family":"Voltura","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":342461,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"French, J.B. 0000-0001-8901-7092","orcid":"https://orcid.org/0000-0001-8901-7092","contributorId":13944,"corporation":false,"usgs":true,"family":"French","given":"J.B.","affiliations":[],"preferred":false,"id":342460,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":5224767,"text":"5224767 - 2007 - Herbivory by resident geese: The loss and recovery of wild rice along the tidal Patuxent River","interactions":[],"lastModifiedDate":"2018-08-15T16:42:09","indexId":"5224767","displayToPublicDate":"2010-06-16T12:18:32","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2508,"text":"Journal of Wildlife Management","active":true,"publicationSubtype":{"id":10}},"title":"Herbivory by resident geese: The loss and recovery of wild rice along the tidal Patuxent River","docAbstract":"Well known for a fall spectacle of maturing wild rice (Zizania aquatica) and migrant waterbirds, the tidal freshwater marshes of the Patuxent River, Maryland, USA, experienced a major decline in wild rice during the 1990s. We conducted experiments in 1999 and 2000 with fenced exclosures and discovered herbivory by resident Canada geese (Branta canadensis). Grazing by geese eliminated rice outside exclosures, whereas protected plants achieved greater size, density, and produced more panicles than rice occurring in natural stands. The observed loss of rice on the Patuxent River reflects both the sensitivity of this annual plant to herbivory and the destructive nature of an overabundance of resident geese on natural marsh vegetation. Recovery of rice followed 2 management actions: hunting removal of approximately 1,700 geese during a 4-year period and reestablishment of rice through a large-scale fencing and planting program.

The birds occupied territories in primary-succession habitats on growing point bars. They were most common in mixed stands of Tessaria integrifolia (Asteraceae) and Gynerium sagittatum (Gramineaceae) interspersed with bare sand areas. The uneven height of the Tessaria canopy, which resulted in openings in the vegetation large enough for the birds to flycatch, was an important habitat feature. Birds obtained insects, which formed about 96% of the diet, by aerial hawking (91%), perch gleaning (6%), and hover gleaning (3%). They also fed on fruit. Territory sizes ranged from 0.04 to 0.25 ha. Of nine territories that we observed closely, six were occupied by two birds each, two by one bird each, and one by three birds. Every territory had one dominant individual who was primarily responsible for territory defense; the other birds were associates. Vocalizations given included the fee-bee-o song, a two-syllable song, and the pit note, which are also given on the breeding grounds. A series of pits given increasingly rapidly signaled a territorial interaction. In aggressive encounters, the birds (1) interacted vocally, remaining on their territories and counter calling or exchanging agitated calls; (2) moved toward a common territorial boundary and engaged in a vocal duel; or (3) the dominant chased intruders out of the territory. Chases were most common when a wave of new birds entered the area. Dominant birds, which sang the full song, were probably adult males. Immature males do not sing a full song, and females are not known to sing in nature. Associate individuals were likely females or young males.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ornitologia Neotropical","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6772_Foster.pdf","usgsCitation":"Foster, M., 2007, Winter behavior and ecology of the Alder Flycatcher (Empidonax alnorum) in Peru: Ornitologia Neotropical, v. 18, p. 171-186.","productDescription":"171-186","startPage":"171","endPage":"186","numberOfPages":"16","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201530,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49abe4b07f02db5c5965","contributors":{"authors":[{"text":"Foster, M.S. 0000-0001-8272-4608","orcid":"https://orcid.org/0000-0001-8272-4608","contributorId":10116,"corporation":false,"usgs":true,"family":"Foster","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":342696,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":5224692,"text":"5224692 - 2007 - Mercury and growth of tree swallows at Acadia National Park, and at Orono, Maine, USA","interactions":[],"lastModifiedDate":"2016-10-27T10:52:08","indexId":"5224692","displayToPublicDate":"2010-06-16T12:18:31","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1552,"text":"Environmental Monitoring and Assessment","onlineIssn":"1573-2959","printIssn":"0167-6369","active":true,"publicationSubtype":{"id":10}},"title":"Mercury and growth of tree swallows at Acadia National Park, and at Orono, Maine, USA","docAbstract":"In 1997 and 1998 we weighed nestling tree swallows (Tachycineta bicolor) and measured selected body components at two colonies: Acadia National Park on Mt.

In 1997, mean linear growth rates of the wing (chord), tail, tarsus, and mandible were higher at Acadia than at Orono.

On average among locations, total mercury (THg) biomagnified 2 to 4-fold from food to eggs and 9 to 18-fold from food to feathers. These are minimum values because the proportion of transferable methyl mercury (MeHg) of the THg in insects varies (i.e., 35%–95% of THg) in food boluses. THg was highest in food boluses at Aunt Betty Pond at Acadia, whereas THg in eggs was highest at the Superfund site. A few eggs from nests at each of these locations exceeded the threshold (i.e., 800–1,000 ng/g, wet wt.) of embryotoxicity established for Hg. Hatching success was 88.9% to 100% among locations, but five eggs failed to hatch from 4 of the 11 clutches in which an egg exceeded this threshold. MeHg in feathers was highest in tree swallows at Aunt Betty Pond and the concentration of THg in bodies was related to the concentration in feathers. Transfer of an average of 80%–92% of the Hg in bodies to feathers may have enhanced nestling survival. Residues of Hg in tissues of tree swallows in the Northeast seem higher than those of the Midwest.

Habitat loss and fragmentation due to land use changes is thought to be one of the major factors contributing to the decline. BBS routes, the primary source for monitoring bird population trends, include 50 sampling stops every 0.8 km. Although data from BBS routes are extrapolated to determine regional trends in bird populations, it is important to understand the effects of habitat changes at the stop-level along BBS routes. Route-level analysis of habitat changes may mask important changes that are occurring at a smaller scale particularly for the cerulean warbler which displays several micro-scale habitat preferences. We are examining cerulean warbler habitat and population changes in its core breeding range of the Ohio Hills and Cumberland Plateau physiographic regions. We quantified land cover changes within 300 m of BBS routes in the core cerulean warbler breeding range of Ohio, West Virginia, and Kentucky by digitizing aerial photographs from two time periods: the 1980s and 2004. We also quantified land cover changes within 300 m of BBS routes with the National Land Cover Dataset (NLCD) from 1992 and 2001. The hand-digitized aerial photos will be compared with the NLCD to determine how similar the two methods are in quantifying land cover changes. We then compared stop-level land cover changes with stop level changes in cerulean warbler detections within the same time periods along the BBS routes. This will allow for a more detailed analysis of how well habitat changes along BBS routes reflect the changes in cerulean warbler populations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"McElhone, P., Wood, P., and Dawson, D., 2007, Effects of habitat change along Breeding Bird Survey routes in the central Appalachians on Cerulean Warbler population: Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies, v. 61.","productDescription":"131 (abstract)","startPage":"131 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16823,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://24.73.102.130/resource/dynamic/private/PDF/McElhone-131.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":202247,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2ce4b07f02db613ad9","contributors":{"authors":[{"text":"McElhone, P.","contributorId":52302,"corporation":false,"usgs":true,"family":"McElhone","given":"P.","email":"","affiliations":[],"preferred":false,"id":343037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wood, P.W.","contributorId":81608,"corporation":false,"usgs":true,"family":"Wood","given":"P.W.","email":"","affiliations":[],"preferred":false,"id":343039,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dawson, D.","contributorId":72901,"corporation":false,"usgs":true,"family":"Dawson","given":"D.","email":"","affiliations":[],"preferred":false,"id":343038,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5224890,"text":"5224890 - 2007 - Using a novel micro-sampling technique to monitor the effects of methylmercury on the eggs of wild birds","interactions":[],"lastModifiedDate":"2012-02-02T00:15:29","indexId":"5224890","displayToPublicDate":"2010-06-16T12:18:31","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3139,"text":"Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies","active":true,"publicationSubtype":{"id":10}},"title":"Using a novel micro-sampling technique to monitor the effects of methylmercury on the eggs of wild birds","docAbstract":"Methylmercury is the predominant chemical form of mercury reported in the eggs of wild birds. The embryo is the life stage at which birds are most sensitive to methylmercury. Protective guidelines have been based largely on captive-breeding studies done with chickens (Gallus domesticus), mallards (Anas platyrhynchos), and ring-necked pheasants (Phasianus colchicus). Typically these studies are cost and time prohibitive. In the past, researchers have used either egg injections or the ?sample egg? technique to determine contaminant effects on bird eggs. Both techniques have their limitations. As an alternative to the above methods and because most of the methylmercury is found in the albumen we have developed a novel, less invasive technique, to micro-sample the albumen of eggs in the field. An albumen sample would be analyzed and then compared to the hatching success of that egg. Using the micro-sampling procedure, the egg is oriented with the blunt end up and the pointed end down. A vent hole is drilled at the top to relieve pressure. Approximately one third up from the bottom, a withdrawal site is drilled just until the inner shell membrane is exposed. A syringe with a 21 or 18 gauge needle is gently inserted just into the egg and approximately 200?300?l of albumen is removed. Almost concurrently this site and then the vent are sealed. Thus far we have experimented with both chicken and mallard eggs in the laboratory. We sampled chicken eggs at days 0 and 3 of incubation with a hatching success of 76% and 70%, respectively. Neither group was significantly different from control eggs (P=0.52, 0.54). Field studies are in progress using this technique in which birds are allowed to incubate their own eggs. We envision micro-sampling to be a tool that researchers and managers could use in the field to determine the effects of mercury or other contaminants in bird populations. Micro-sampling would reduce the impact on the sampled population and could be used to monitor sensitive species without impacting reproduction and recruitment.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Klimstra, J., Stebbins, K., and Heinz, G.H., 2007, Using a novel micro-sampling technique to monitor the effects of methylmercury on the eggs of wild birds: Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies, v. 61.","productDescription":"129 (abstract)","startPage":"129 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16822,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://24.73.102.130/resource/dynamic/private/PDF/Klimstra-129.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":202568,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a15e4b07f02db6030e8","contributors":{"authors":[{"text":"Klimstra, J.D.","contributorId":62328,"corporation":false,"usgs":true,"family":"Klimstra","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":343035,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stebbins, K.R.","contributorId":55558,"corporation":false,"usgs":true,"family":"Stebbins","given":"K.R.","email":"","affiliations":[],"preferred":false,"id":343034,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Heinz, G.

When selecting variables to monitor, managers first need to carefully consider their objectives, the geographic and temporal scale at which they will operate, and the effort needed to implement the program. Generally, monitoring can be divided into two categories: index and inferential. Although index monitoring is usually easier to implement, analysis of index data requires strong assumptions about consistency in detection rates over time and space, and parameters are often biasednot accounting for detectability and spatial variation. In most cases, individuals are not always available for detection during sampling periods, and the entire area of interest cannot be sampled. Conversely, inferential monitoring is more rigorous because it is based on nearly unbiased estimators of spatial distribution. Thus, we recommend that detectability and spatial variation be considered for all monitoring programs that intend to make inferences about the target population or the area of interest. Application of these techniques is especially important for the monitoring of Threatened and Endangered (T&E) species because it is critical to determine if population size is increasing or decreasing with some level of certainty. Use of estimation-based methods and probability sampling will reduce many of the biases inherently associated with index data and provide meaningful information with respect to changes that occur in target populations. We incorporated inferential monitoring into protocols for T&E species spanning a wide range of taxa on the Cherokee National Forest in the Southern Appalachian Mountains. We review the various approaches employed for different taxa and discuss design issues, sampling strategies, data analysis, and the details of estimating detectability using site occupancy. These techniques provide a science-based approach for monitoring and can be of value to all resource managers responsible for management of T&E species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Klimstra, J., O'Connell, A., Pistrang, M., Lewis, L., Herrig, J., and Sauer, J., 2007, Design and implementation of estimation-based monitoring programs for flora and fauna: A case study on the Cherokee National Forest: Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies, v. 61.","productDescription":"126 (abstract)","startPage":"126 (abs)","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":16821,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://24.73.102.130/resource/dynamic/private/PDF/Klimstra-126.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":202567,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"61","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa9e4b07f02db667eb7","contributors":{"authors":[{"text":"Klimstra, J.D.","contributorId":62328,"corporation":false,"usgs":true,"family":"Klimstra","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":343031,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O'Connell, A.F.

Our study focuses on movement and survival related to the natal location of snail kites in Florida and shows that kites, in addition to exhibiting a high level of site tenacity to breeding regions, also exhibit particular attraction to their natal region. More specifically, we found that estimates of movement from post-dispersal regions were greater toward natal regions than toward non-natal regions (differences were significant for three of four regions). We also found that estimates of natal philopatry were greater than estimates of philopatry to non-natal regions (differences were statistically significant for two of four regions). A previous study indicated an effect of natal region on juvenile survival; in this study, we show an effect of natal region on adult survival. Estimates of adult survival varied among kites that were hatched in different regions. Adults experienced mortality rates characteristic of the region occupied at the time when survival was measured, but because there is a greater probability that kites will return to their natal region than to any other regions, their survival was ultimately influenced by their natal region. In most years, kites hatched in southern regions had greater survival probabilities than did kites hatched in northern regions. However, during a multiregional drought, one of the northern regions served as a refuge from drought, and during this perturbation, survival was greater for birds hatched in the north. Our study shows that natal location may be important in influencing the ecological dynamics of kites but also highlights the importance of considering temporal variation in habitat conditions of spatially structured systems when attempting to evaluate the conservation value of habitats.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Oecologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00442-007-0729-8","collaboration":"6774_Martin.pdf","usgsCitation":"Martin, J., Kitchens, W., and Hines, J., 2007, Natal location influences movement and survival of a spatially structured population of snail kites: Oecologia, v. 153, no. 2, p. 291-301, https://doi.org/10.1007/s00442-007-0729-8.","productDescription":"291-301","startPage":"291","endPage":"301","numberOfPages":"11","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201480,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":16857,"rank":300,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00442-007-0729-8 ; https://www.springerlink.com/content/avf070ktcexykupa/fulltext.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":293330,"type":{"id":15,"text":"Index Page"},"url":"https://link.springer.com/article/10.1007%2Fs00442-007-0729-8"}],"volume":"153","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-05-26","publicationStatus":"PW","scienceBaseUri":"4f4e4b02e4b07f02db6989fb","contributors":{"authors":[{"text":"Martin, J.","contributorId":18871,"corporation":false,"usgs":true,"family":"Martin","given":"J.","affiliations":[],"preferred":false,"id":342702,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kitchens, W.M.","contributorId":87647,"corporation":false,"usgs":true,"family":"Kitchens","given":"W.M.","affiliations":[],"preferred":false,"id":342704,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hines, J.E. 0000-0001-5478-7230","orcid":"https://orcid.org/0000-0001-5478-7230","contributorId":36885,"corporation":false,"usgs":true,"family":"Hines","given":"J.E.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":342703,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":5224699,"text":"5224699 - 2007 - Patch-occupancy models indicate human activity as major determinant of forest elephant Loxodonta cyclotis seasonal distribution in an industrial corridor in Gabon","interactions":[],"lastModifiedDate":"2014-08-12T10:19:02","indexId":"5224699","displayToPublicDate":"2010-06-16T12:18:00","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1015,"text":"Biological Conservation","active":true,"publicationSubtype":{"id":10}},"title":"Patch-occupancy models indicate human activity as major determinant of forest elephant Loxodonta cyclotis seasonal distribution in an industrial corridor in Gabon","docAbstract":"The importance of human activity and ecological features in influencing African forest elephant ranging behaviour was investigated in the Rabi-Ndogo corridor of the Gamba Complex of Protected Areas in southwest Gabon. Locations in a wide geographical area with a range of environmental variables were selected for patch-occupancy surveys using elephant dung to assess seasonal presence and absence of elephants. Patch-occupancy procedures allowed for covariate modelling evaluating hypotheses for both occupancy in relation to human activity and ecological features, and detection probability in relation to vegetation density. The best fitting models for old and fresh dung data sets indicate that (1) detection probability for elephant dung is negatively related to the relative density of the vegetation, and (2) human activity, such as presence and infrastructure, are more closely associated with elephant distribution patterns than are ecological features, such as the presence of wetlands and preferred fresh fruit. Our findings emphasize the sensitivity of elephants to human disturbance, in this case infrastructure development associated with gas and oil production. Patch-occupancy methodology offers a viable alternative to current transect protocols for monitoring programs with multiple covariates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2006.10.028","collaboration":"6651_Buij.pdf","usgsCitation":"Buij, R., McShea, W., Campbell, P., Lee, M., Dallmeier, F., Guimondou, S., Mackaga, L., Guisseougou, N., Mboumba, S., Hines, J., Nichols, J., and Alonso, A., 2007, Patch-occupancy models indicate human activity as major determinant of forest elephant Loxodonta cyclotis seasonal distribution in an industrial corridor in Gabon: Biological Conservation, v. 135, no. 2, p. 189-201, https://doi.org/10.1016/j.biocon.2006.10.028.","productDescription":"13 p.","startPage":"189","endPage":"201","numberOfPages":"13","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196297,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":292002,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2006.10.028"}],"country":"Gabon","volume":"135","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db6889c3","contributors":{"authors":[{"text":"Buij, R.","contributorId":44632,"corporation":false,"usgs":true,"family":"Buij","given":"R.","affiliations":[],"preferred":false,"id":342406,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McShea, W.J.","contributorId":46187,"corporation":false,"usgs":true,"family":"McShea","given":"W.J.","affiliations":[],"preferred":false,"id":342407,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Campbell, P.","contributorId":99249,"corporation":false,"usgs":true,"family":"Campbell","given":"P.","email":"","affiliations":[],"preferred":false,"id":342409,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lee, M.E.","contributorId":26779,"corporation":false,"usgs":true,"family":"Lee","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":342402,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dallmeier, F.","contributorId":39894,"corporation":false,"usgs":true,"family":"Dallmeier","given":"F.","email":"","affiliations":[],"preferred":false,"id":342405,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Guimondou, S.","contributorId":39087,"corporation":false,"usgs":true,"family":"Guimondou","given":"S.","email":"","affiliations":[],"preferred":false,"id":342404,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mackaga, L.","contributorId":16534,"corporation":false,"usgs":true,"family":"Mackaga","given":"L.","email":"","affiliations":[],"preferred":false,"id":342401,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Guisseougou, N.","contributorId":107393,"corporation":false,"usgs":true,"family":"Guisseougou","given":"N.","email":"","affiliations":[],"preferred":false,"id":342410,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Mboumba, S.","contributorId":12141,"corporation":false,"usgs":true,"family":"Mboumba","given":"S.","email":"","affiliations":[],"preferred":false,"id":342399,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Hines, J.E. 0000-0001-5478-7230","orcid":"https://orcid.org/0000-0001-5478-7230","contributorId":36885,"corporation":false,"usgs":true,"family":"Hines","given":"J.E.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":342403,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Nichols, J.D. 0000-0002-7631-2890","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":14332,"corporation":false,"usgs":true,"family":"Nichols","given":"J.D.","affiliations":[],"preferred":false,"id":342400,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Alonso, A.","contributorId":57561,"corporation":false,"usgs":true,"family":"Alonso","given":"A.","email":"","affiliations":[],"preferred":false,"id":342408,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}} ,{"id":5224729,"text":"5224729 - 2007 - Immunotoxicity of trenbolone acetate in Japanese quail","interactions":[],"lastModifiedDate":"2013-03-15T20:26:39","indexId":"5224729","displayToPublicDate":"2010-06-16T00:00:00","publicationYear":"2007","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2481,"text":"Journal of Toxicology and Environmental Health, Part A","active":true,"publicationSubtype":{"id":10}},"title":"Immunotoxicity of trenbolone acetate in Japanese quail","docAbstract":"Trenbolone acetate is a synthetic androgen that is currently used as a growth promoter in many meat-exporting countries. Despite industry laboratories classifying trenbolone as nonteratogenic, data showed that embryonic exposure to this androgenic chemical altered development of the immune system in Japanese quail. Trenbolone is lipophilic, persistent, and released into the environment in manure used as soil fertilizer. This is the first study to date to assess this chemical's immunotoxic effects in an avian species. A one-time injection of trenbolone into yolks was administered to mimic maternal deposition, and subsequent effects on the development and function of the immune system were determined in chicks and adults. Development of the bursa of Fabricius, an organ responsible for development of the humoral arm of the immune system, was disrupted, as indicated by lower masse, and smaller and fewer follicles at day 1 of hatch. Morphological differences in the bursas persisted in adults, although no differences in either two measures of immune function were observed. Total numbers of circulating leukocytes were reduced and heterophil-lymphocyte ratios were elevated in chicks but not adults. This study shows that trenbolone acetate is teratogenic and immunotoxic in Japanese quail, and provides evidence that the quail immune system may be fairly resilient to embryonic endocrine-disrupting chemical-induced alterations following no further exposure posthatch.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Toxicology and Environmental Health, Part A","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1080/15287390600755026","collaboration":"6681_Quinn.pdf","usgsCitation":"Quinn, M., McKernan, M., Lavoie, E., and Ottinger, M.A., 2007, Immunotoxicity of trenbolone acetate in Japanese quail: Journal of Toxicology and Environmental Health, Part A, v. 70, no. 1, p. 88-93, https://doi.org/10.1080/15287390600755026.","productDescription":"88-93","startPage":"88","endPage":"93","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201497,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269418,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/15287390600755026"}],"volume":"70","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-02-24","publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db6887ba","contributors":{"authors":[{"text":"Quinn, M.J.","contributorId":50990,"corporation":false,"usgs":true,"family":"Quinn","given":"M.J.","affiliations":[],"preferred":false,"id":342497,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McKernan, M.","contributorId":103388,"corporation":false,"usgs":true,"family":"McKernan","given":"M.","email":"","affiliations":[],"preferred":false,"id":342500,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lavoie, E.T.","contributorId":94767,"corporation":false,"usgs":true,"family":"Lavoie","given":"E.T.","email":"","affiliations":[],"preferred":false,"id":342498,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ottinger, M.

Premining streamflow characteristics and streamflow gain-loss variation were determined so that pre- and postmining gain-loss characteristics could be compared. This report describes the methods used in this study and the results of two streamflow-measurement sets collected during low-flow conditions.\r\n\r\nStreamflow gain-loss measurements were collected using rhodamine WT and sodium bromide tracers at four sites spanning the mine-permit area on June 26-28, 2007. Streamflows were estimated and compared between four measurement sites within three stream subreaches of the study reach. Data from two streamflow-gaging stations on Hubbard Creek upstream and downstream from the mine-permit area were evaluated. Streamflows at the stations were continuous, and flow at the upstream station nearly always exceeded the streamflow at the downstream station. Furthermore, streamflow at both stations showed similar diurnal patterns with traveltime offsets.\r\n\r\nOn June 26, streamflow from the gain-loss measurements was greater at site 1 (most upstream site) than at site 4 (most downstream site); on June 27, streamflow was greater at site 4 than at site 2; and on June 27, there was no difference in streamflow between sites 2 and 3. Data from streamflow-gaging stations 09132940 and 09132960 showed diurnal variations and overall decreasing streamflow over time. The data indicate a dynamic system, and streamflow can increase or decrease depending on hydrologic conditions. The streamflow within the study reach was greater than the streamflows at either the upstream or downstream stations.\r\n\r\nA second set of gain-loss measurements was collected at sites 2 and 4 on November 8-9, 2007. On November 8, streamflow was greater at site 4 than at site 2, and on the following day, November 9, streamflow was greater at site 2 than at site 4. Data collection on November 8 occurred while the streamflow was increasing due to contributions from stream ice melting throughout different parts of the basin. Data collection on November 9 occurred earlier in the day with less stream ice melting and more steady-state conditions, so the indication that streamflow decreased between sites 2 and 4 may be more accurate.\r\n\r\nDiurnal variations in streamflow are common at both the upper and the lower streamflow-gaging stations. The upper streamflow-gaging station shows a melt-freeze influence from tributaries to Hubbard Creek during the winter season. Downstream from the study reach, observed diurnal variation is likely due to evapotranspiration associated with dense flood-plain vegetation, which consumes water from the creek during the middle of the day. Varying diurnal patterns in streamflow, combined with possible variations in tributary inflows to Hubbard Creek in the study reach, probably account for the observed variations in streamflow at the tracer measurement sites.\r\n\r\nDuring both sampling periods in June and November 2007, conditions were less than ideal and not steady state. The June 27 sampling indicates that the streamflow was increasing between measurement sites 2 and 4, and the November 9 sampling indicates that the streamflow was decreasing between measurement sites 2 and 4. The data collected during the diurnal and day-to-day variations in streamflow indicated that the streamflow reach is dynamic and can be gaining, losing, or constant. \r\n","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/sir20095271","collaboration":"Prepared in cooperation with Bowie Mining Company","usgsCitation":"Ruddy, B.C., and Williams, C.A., 2007, Evaluation of Streamflow Gain-Loss Characteristics of Hubbard Creek, in the Vicinity of a Mine-Permit Area, Delta County, Colorado, 2007: U.S. Geological Survey Scientific Investigations Report 2009-5271, vi, 19 p. , https://doi.org/10.3133/sir20095271.","productDescription":"vi, 19 p.

From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at the district to document the presence of species within its boundaries. Park staff also carried out extensive infrared-triggered camera work for medium and large mammals from 2002-2005 and results from that effort are reported here. Our spatial sampling design for all taxa employed a combination of random and nonrandom survey sites. Survey effort was greatest for medium and large mammals and herpetofauna. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the district. We also provide an overview of previous survey efforts in the district. We use data from our inventory and other surveys to compile species lists and to assess inventory completeness. \r\n\r\nThe survey effort for herpetofauna, birds, and medium and large mammals was the most comprehensive ever undertaken in the district. We recorded a total of 320 plant and vertebrate species, including 21 species not previously found in the district (Table 1). Based on a review of our inventory and past research at the district, there have been a total of 723 species of plants and vertebrates found there. We believe inventories for most taxonomic groups are nearly complete. \r\n\r\nBased on our surveys, we believe the native plant and vertebrate community compositions of the district are relatively intact, though some species loss has occurred and threats are increasing, particularly to herpetofauna and larger mammals. Of particular note is the relatively small number of non-native species and their low abundance in the district, which is in contrast to many nearby natural areas. Rapidly expanding development on the west, north, and east sides of the district is cause for concern that the park continue its commitment to environmental restoration, which is largely responsible for reducing the threats posed by non-native plants. With continued maintenance of natural processes and the ecological structure of the park's biodiversity, the park will become an increasingly important place to both the general public and the scientific community.\r\n\r\nThis report supersedes results reported in Powell et al.

We used our data as well as data from previous research to compile species lists for the memorial, assess inventory completeness, and make suggestions on future monitoring efforts. \r\n\r\nThere have been 940 species of plants and vertebrates recorded at Coronado NM (Table 1), of which 46 (5%) are non-native. The species richness of the memorial is one of the highest in the Sonoran Desert Network of park units, third only to park units that are two and one-half (Chiricahua National Monument), 19 (Saguaro National Park) and 70 (Organ Pipe Cactus National Monument) times larger in area. The high species diversities are due to the large elevational gradient, overlap of bigeographical regions, wide range of geology and soils, and diverse vegetation communities present at the memorial. \r\n\r\nChanges in species composition have occurred at the memorial over the last 20 years in all major taxonomic groups. These changes are likely due to increases in grassy plant species (both native and non-native) at the lower elevations of the memorial. We suspect that grassy plant cover has increased because of changes in grazing intensity, introduction of some non-native species, and a recent fire. All recent vertebrate inventories have yielded grassland obligate species not previously recorded at the memorial. \r\n\r\nBased on the review of past studies, we believe the inventory for most taxa, except bats, is nearly complete, though some rare or elusive species will likely be added with additional survey effort.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20071393","collaboration":"Prepared in cooperation with the University of Arizona School of Natural Resources","usgsCitation":"Powell, B., Swann, D.E., and Halvorson, W., 2007, Vascular Plant and Vertebrate Inventory of Coronado National Memorial (Version 1.0): U.S. Geological Survey Open-File Report 2007-1393, xiv, 114 p., https://doi.org/10.3133/ofr20071393.","productDescription":"xiv, 114 p.","onlineOnly":"Y","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":118675,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2007_1393.jpg"},{"id":12849,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1393/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.4,31.3 ], [ -110.4,31.4 ], [ -110.2,31.4 ], [ -110.2,31.3 ], [ -110.4,31.3 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7afde4b0b2908510dd80","contributors":{"editors":[{"text":"Schmidt, Cecilia A.","contributorId":47483,"corporation":false,"usgs":true,"family":"Schmidt","given":"Cecilia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":742840,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Powell, Brian F.","contributorId":25644,"corporation":false,"usgs":true,"family":"Powell","given":"Brian F.","affiliations":[],"preferred":false,"id":302905,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Swann, Don E.","contributorId":90002,"corporation":false,"usgs":true,"family":"Swann","given":"Don","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":302907,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halvorson, William L.","contributorId":97194,"corporation":false,"usgs":true,"family":"Halvorson","given":"William L.","affiliations":[],"preferred":false,"id":302908,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":97656,"text":"ofr20071295 - 2007 - Vascular Plant and Vertebrate Inventory of Tonto National Monument","interactions":[],"lastModifiedDate":"2012-02-10T00:11:49","indexId":"ofr20071295","displayToPublicDate":"2009-07-08T00:00:00","publicationYear":"2007","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2007-1295","title":"Vascular Plant and Vertebrate Inventory of Tonto National Monument","docAbstract":"This report summarizes the results of the first biological inventory of plants and vertebrates at Tonto National Monument (NM). From 2001 to 2003, we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at Tonto NM to record species presence. We focused most of our efforts along the Cave Springs riparian area, but surveyed other areas as well. We recorded 149 species in the riparian area, and 369 species overall in the monument, including 65 plant species and four bird species that were previously unrecorded for the monument. We recorded 78 plant species in the riparian area that previous studies had not indicated were present there. \r\n\r\nSeveral species of each taxonomic group were found only in the riparian area, suggesting that because of their concentration in this small area these populations are vulnerable to disturbance and may be of management concern. Four of the bird species that we recorded (Bell's vireo, yellow warbler, summer tanager, and Abert's towhee) have been identified as riparian 'obligate' species by other sources. Bird species that are obligated to riparian areas are targets of conservation concern due to widespread degradation of riparian areas in the desert southwest over the last century. \r\n\r\nThe flora and fauna of the riparian area would benefit from continued limited public access. The dependence of the riparian area on the spring and surface flow suggests monitoring of this resource per se would benefit management of the riparian area's flora and fauna as well. The monument would benefit from incorporating monitoring protocols developed by the Sonoran Desert Network Inventory and Monitoring program rather than initiating a separate program for the riparian area. Park managers can encourage the Inventory and Monitoring program to address the unique monitoring challenges presented by small spatial areas such as this riparian area, and can request specific monitoring recommendations. We suggest that repeat inventories for vertebrates, and census (rather than sampling) of perennial vegetation may be the most effective long-term monitoring strategies in the riparian area to verify species persistence through time in this unique and spatially limited environment.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20071295","collaboration":"Prepared in cooperation with the University of Arizona School of Natural Resources","usgsCitation":"Albrecht, E.W., Powell, B., Halvorson, W., and Schmidt, C., 2007, Vascular Plant and Vertebrate Inventory of Tonto National Monument (Version 1.0): U.S. Geological Survey Open-File Report 2007-1295, xii, 57 p., https://doi.org/10.3133/ofr20071295.","productDescription":"xii, 57 p.","onlineOnly":"Y","temporalStart":"2001-01-01","temporalEnd":"2003-12-31","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":125449,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2007_1295.jpg"},{"id":12805,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1295/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.8,33.3 ], [ -110.8,33.4 ], [ -110.7,33.4 ], [ -110.7,33.3 ], [ -110.8,33.3 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48d4e4b07f02db548efa","contributors":{"authors":[{"text":"Albrecht, Eric W.","contributorId":8568,"corporation":false,"usgs":true,"family":"Albrecht","given":"Eric","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":302782,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powell, Brian F.","contributorId":25644,"corporation":false,"usgs":true,"family":"Powell","given":"Brian F.","affiliations":[],"preferred":false,"id":302783,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halvorson, William L.","contributorId":97194,"corporation":false,"usgs":true,"family":"Halvorson","given":"William L.","affiliations":[],"preferred":false,"id":302785,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schmidt, Cecilia A.","contributorId":25645,"corporation":false,"usgs":true,"family":"Schmidt","given":"Cecilia A.","affiliations":[],"preferred":false,"id":302784,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":97639,"text":"gip57 - 2007 - South San Francisco Bay, California","interactions":[],"lastModifiedDate":"2016-07-27T10:44:49","indexId":"gip57","displayToPublicDate":"2009-06-27T00:00:00","publicationYear":"2007","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":315,"text":"General Information Product","code":"GIP","onlineIssn":"2332-354X","printIssn":"2332-3531","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"57","title":"South San Francisco Bay, California","docAbstract":"The U.S. Geological Survey, in cooperation with the California Coastal Conservancy and the National Oceanic and Atmospheric Administration, mapped the floor of south San Francisco Bay and adjoining land using single-beam sonar and airborne lidar (light detection and ranging).

With sea level rise greater than marsh elevation increase, marshes can be submerged, marsh soils become waterlogged, and plant growth becomes stressed, often resulting in conversion of vegetation-dominated marsh to mudflat or open water habitat. Given that the rate of sea level rise is expected to accelerate over the next century and that some marshes in the northeast are becoming submerged (e.g., Jamaica Bay, NY), it is important to understand the processes that control marsh development.

Berberis thunbergii (Japanese barberry), Frangula alnus (glossy or alder buckthorn) and Lythrum salicaria (purple loosestrife) are invasive species known to reduce native plant diversity and are thus of great concern to Acadia National Park. Pollinators visit them for nectar and pollen. The effects of invasive plant species on pollinator behavior were investigated by comparing pollinator visitation to co-flowering native and invasive species with visitation to native species growing alone. The effect of invasives on pollination of native plants was studied by comparing fruit set in patches of the native species growing near invasives with patches far from invasive species in Acadia National Park. The coflowering pairs were as follows: in the spring native Vaccinium angustifolium (lowbush blueberry) was paired with B. thunbergii; in early summer native Viburnum nudum (wild raisin) was paired with F. alnus ; in late summer native Spiraea alba (meadowsweet) was paired with L. salicaria. We investigated whether these invasives competed with native plants for pollinators in Acadia and thus negatively affected native plant reproduction. Our objectives were to determine: 1) the influence, if any, of each invasive on pollinator visitation to a co-flowering native species, 2) factors that might affect visitation, 3) invasive pollen transfer to native plants, and 4) whether invasives influence native plant reproduction (fruit set). Our findings indicate that at times the number of flower visitors to natives was lower or the species composition of visitors different when invasives were present, that invasives sometimes attracted more pollinators, that generally the invasives were more rewarding as far as nectar and pollen availability for pollinators, and that generally native plant fruit set and seed set was not significantly lowered in the presence of the invasive. In fact, in one year fruit set of S. alba was significantly greater in the presence of L. salicaria. The number of invasive pollen grains on native stigmas was extremely low; on average less than one grain per stigma. These fruit set and pollen deposition findings indicate that native plant reproduction was not adversely affected in the short term by these invasive species and that therefore competition between the native and invasive species for pollinators did not occur. Native bee populations monitored in 2004-2005 at sites with and without B. thunbergii and/or F. alnus indicated a greater abundance of native bees at sites with these invasives present. Native bees collected from the native and invasive plants were compared with historical records to assess whether invasive plants favor different bee species than those that formerly predominated on Mount Desert Island. This does not appear to be the case. Several species of bumble bees (Bombus spp.) as well as nine solitary bee species were found that were not documented by the Procter surveys of 1917-1940. Collecting of native bees was limited to the study plants, which may, in part, explain why some bee species documented in the Procter Surveys were not found in the present research. A field guide for identification of native bumble bees has been produced to help Park Natural Resource personnel monitor the status of native bee populations in Acadia. Other educational materials were also developed, aimed at educating Park visitors by exposing them to: 1) the role of native plants and their bee pollinators in terrestrial ecosystems; 2) the effects of invasive plants on native plant-pollinator mutualisms; 3) the need for conserving native bees and other pollinators; and 4) conservation strategies for protecting and enhancing native plant-pollinator mutualisms in the Park.
