The Gull-billed Tern (<i>Sterna nilotica</i>), Common Tern (<i>S</i>. <i>hirundo</i>), Black Skimmer (<i>Rynchops niger</i>), and American Oystercatcher (<i>Haematopus palliatus</i>), species of concern in Virginia, nest on low shelly perimeters of salt marsh islands on the Eastern Shore of Virginia. Marsh shellpiles are free of mammalian predators, but subject to frequent floods that reduce reproductive success. In an attempt to examine nest-site selection, enhance habitat, and improve hatching success, small (<span>2 × 2 m</span>) plots on five island shellpiles were experimentally elevated, and nest-site selection and hatching success were monitored from 1 May to 1 August, 2002. In addition, location, elevation, and nesting performance of all other nests in the colonies were also monitored. No species selected the elevated experimental plots preferentially over adjacent control plots at any of the sites. When all nests were considered, Common Tern nests were located significantly lower than were random point elevations at two sites, as they tended to concentrate on low-lying wrack. At two other sites, however, Common Tern nests were significantly higher than were random points. Gull-billed Terns and American Oystercatchers showed a weak preference for higher elevations on bare shell at most sites. Hatching success was not improved on elevated plots, despite the protection they provided from flooding. Because of a 7 June flood, when 47% of all nests flooded, hatching success for all species was low. Nest elevation had the strongest impact on a nest's probability of hatching, followed by nest-initiation date. Predation rates were high at small colonies, and Ruddy Turnstones (<i>Arenaria interpres</i>) depredated 90% of early Gull-billed Tern nests at one shellpile. The importance of nest elevation and flooding on hatching success demonstrates the potential for management of certain waterbird nesting sites. Facing threats from predators on barrier islands and rising sea levels especially in the mid-Atlantic region, several species of nesting waterbirds may benefit dramatically with modest manipulation of even small habitat patches on isolated marsh islands.</p>","language":"English","publisher":"BioOne","doi":"10.1648/0273-8570-75.4.317","usgsCitation":"Rounds, R., Erwin, R., and Porter, J., 2004, Nest-site selection and hatching success of waterbirds in coastal Virginia: Some results of habitat manipulation: Journal of Field Ornithology, v. 75, no. 4, p. 317-329, https://doi.org/10.1648/0273-8570-75.4.317.","productDescription":"13 p.","startPage":"317","endPage":"329","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202565,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Virginia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -76.761474609375,\n              38.74551518488265\n            ],\n            [\n              -77.14599609375,\n              38.59970036588819\n            ],\n            [\n              -77.442626953125,\n              37.75334401310656\n            ],\n            [\n              -77.113037109375,\n              36.53612263184686\n            ],\n            [\n              -75.35522460937499,\n              36.61552763134925\n            ],\n            [\n              -76.256103515625,\n              38.35027253825765\n            ],\n            [\n              -76.761474609375,\n              38.74551518488265\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"75","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4affe4b07f02db697c9d","contributors":{"authors":[{"text":"Rounds, R.A.","contributorId":69274,"corporation":false,"usgs":true,"family":"Rounds","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":341528,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Erwin, R.M.","contributorId":57396,"corporation":false,"usgs":true,"family":"Erwin","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":341527,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Porter, J.H.","contributorId":53921,"corporation":false,"usgs":true,"family":"Porter","given":"J.H.","email":"","affiliations":[],"preferred":false,"id":341526,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Under the AHM paradigm, predictions from a set of models that reflect key uncertainties about processes underlying population dynamics are used in coordination with optimization software to determine an optimal set of harvest decisions. Managers use comparisons of the predictive abilities of these models to gauge the relative truth of different hypotheses about density-dependent recruitment and survival, with better-predicting models giving more weight to the determination of harvest regulations. We tested the effectiveness of this strategy by examining convergence rates of 'predictor' models when the true model for population dynamics was known a priori. We generated time series for cases when the a priori model was 1 of the predictor models as well as for several cases when the a priori model was not in the model set. We further examined the addition of different levels of uncertainty into the variance structure of predictor models, reflecting different levels of confidence about estimated parameters. We showed that in certain situations, the model-selection process favors a predictor model that incorporates the hypotheses of additive harvest mortality and weakly density-dependent recruitment, even when the model is not used to generate data. Higher levels of predictor model variance led to decreased rates of convergence to the model that generated the data, but model weight trajectories were in general more stable. We suggest that predictive models should incorporate all sources of uncertainty about estimated parameters, that the variance structure should be similar for all predictor models, and that models with different functional forms for population dynamics should be considered for inclusion in predictor model sets. All of these suggestions should help lower the probability of erroneous learning in mallard ABM and adaptive management in general.</p>","language":"English","publisher":"BioOne Complete","doi":"10.2193/0022-541X(2004)068[1065:EMAMMW]2.0.CO;2","usgsCitation":"Conn, P., and Kendall, W., 2004, Evaluating mallard adaptive management models with time series: Journal of Wildlife Management, v. 68, no. 4, p. 1065-1081, https://doi.org/10.2193/0022-541X(2004)068[1065:EMAMMW]2.0.CO;2.","productDescription":"17 p.","startPage":"1065","endPage":"1081","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202140,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fb052","contributors":{"authors":[{"text":"Conn, P.B.","contributorId":73974,"corporation":false,"usgs":true,"family":"Conn","given":"P.B.","email":"","affiliations":[],"preferred":false,"id":341574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kendall, W.

We chose areas based on their importance to migratory bird populations, agency concerns about marsh loss and sea-level rise, and availability of historic imagery. We georeferenced and processed aerial photographs from a variety of sources ranging from 1932 to 1994. Of particular interest were changes in total salt marsh area, tidal creeks, tidal flats, tidal and non-tidal ponds, and open water habitats. Nauset Marsh, within Cape Cod National Seashore, experienced an annual marsh loss of 0.40% (19% from 1947 to 1994) with most loss attributed to sand overwash and conversion to open water. At Forsythe National Wildlife Refuge in southern New Jersey, annual loss was 0.27% (17% from 1932 to 1995), with nearly equal attribution of loss to open water and tidal pond expansion. At Curlew Bay, Virginia, annual loss was 0.20% (9% from 1949 to 1994) and almost entirely due to perimeter erosion to open water. At Gull Marsh, Virginia, a site chosen because of known erosional losses, we recorded the highest annual loss rate, 0.67% per annum, again almost entirely due to erosional, perimeter loss. In contrast, at the southernmost site, Mockhorn Island Wildlife Management Area, Virginia, there was a net gain of 0.09% per annum (4% from 1949 to 1994), with tidal flats becoming increasingly vegetated. Habitat. implications for waterbirds are considerable; salt marsh specialists such as laughing gulls (<i>Larus atricilla</i>), Forster's terns (<i>Sterna forsteri</i>), black rail, (<i>Laterallus jamaicensis</i>), seaside sparrow (<i>Ammodramus maritimus</i>), and saltmarsh sharp-tailed sparrow (<i>Ammodramus caudacutus</i>) are particularly at risk if these trends continue, and all but the laughing gull are species of concern to state and federal managers.</p>","language":"English","publisher":"BioOne Complete","doi":"10.1672/0277-5212(2004)024[0891:CILMMA]2.0.CO;2","usgsCitation":"Erwin, R., Sanders, G., and Prosser, D., 2004, Changes in lagoonal marsh morphology at selected northeastern Atlantic coast sites of significance to migratory waterbirds: Wetlands, v. 24, no. 4, p. 891-903, https://doi.org/10.1672/0277-5212(2004)024[0891:CILMMA]2.0.CO;2.","productDescription":"13 p.","startPage":"891","endPage":"903","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202242,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Massachusetts, New Jersey, Virginia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -74.8388671875,\n              39.99395569397331\n            ],\n            [\n              -76.2890625,\n              39.198205348894795\n            ],\n            [\n              -75.95947265625,\n              37.84015683604136\n            ],\n            [\n              -74.86083984375,\n              38.30718056188316\n            ],\n            [\n              -73.93798828125,\n              39.30029918615029\n            ],\n            [\n              -73.5205078125,\n              40.3130432088809\n            ],\n            [\n              -72.31201171875,\n              40.730608477796636\n            ],\n            [\n              -71.25732421875,\n              41.32732632036622\n            ],\n            [\n              -70.5322265625,\n              41.244772343082076\n            ],\n            [\n              -69.8291015625,\n              41.5579215778042\n            ],\n            [\n              -69.76318359375,\n              42.06560675405716\n            ],\n            [\n              -71.38916015625,\n              42.21224516288584\n            ],\n            [\n              -73.828125,\n              40.84706035607122\n            ],\n            [\n              -74.8388671875,\n              39.99395569397331\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"24","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e5e4b07f02db5e6d12","contributors":{"authors":[{"text":"Erwin, R.M.","contributorId":57396,"corporation":false,"usgs":true,"family":"Erwin","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":341597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sanders, G.M.","contributorId":69665,"corporation":false,"usgs":true,"family":"Sanders","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":341599,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Prosser, D.J. 0000-0002-5251-1799","orcid":"https://orcid.org/0000-0002-5251-1799","contributorId":65185,"corporation":false,"usgs":true,"family":"Prosser","given":"D.J.","affiliations":[],"preferred":false,"id":341598,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Plant individuals can be marked with, e.g., plastic tags, but often the coordinates of an individual may be sufficient to identify it. Vascular plants in temperate latitudes have a pronounced seasonal life–cycle, so most plant demographers survey their study plots once a year often during or shortly after flowering. Life–states are pervasive in plants, hence the results of a demographic study for an individual can be summarized in a familiar encounter history, such as 0VFVVF000. A zero means that an individual was not seen in a year and a letter denotes its state for years when it was seen aboveground. V and F here stand for vegetative and flowering states, respectively. Probabilities of survival and state transitions can then be obtained by mere counting.</span><br><span>Problems arise when there is an unobservable dormant state, i.e., when plants may stay belowground for one or more growing seasons. Encounter histories such as 0VF00F000 may then occur where the meaning of zeroes becomes ambiguous. A zero can either mean a dead or a dormant plant. Various ad hoc methods in wide use among plant ecologists have made strong assumptions about when a zero should be equated to a dormant individual. These methods have never been compared among each other. In our talk and in Kéry et al. (submitted), we show that these ad hoc estimators provide spurious estimates of survival and should not be used.</span><br><span></span></p><p><span>In contrast, if detection probabilities for aboveground plants are known or can be estimated, capturerecapture (CR) models can be used to estimate probabilities of survival and state–transitions and the fraction of the population that is dormant. We have used this approach in two studies of terrestrial orchids, </span><i>Cleistes bifaria</i><span> (Kéry et al., submitted) and </span><i>Cypripedium reginae</i><span>(Kéry &amp; Gregg, submitted) in West Virginia, U.S.A. For Cleistes, our data comprised one population with a total of 620 marked ramets over 10 years, and for </span><i>Cypripedium</i><span>, two populations with 98 and 258 marked ramets over 11 years. We chose the ramet (= single stem or shoot) as the demographic unit of our study since there was no way distinguishing among genets (genet = genetical individual, i.e., the “individual” that animal ecologists are mostly concerned with). This will introduce some non–independence into the data, which can nevertheless be dealt with easily by correcting variances for overdispersion. Using ramets instead of genets has the further advantage that individuals can be assigned to a state such as flowering or vegetative in an unambiguous manner. This is not possible when genets are the demographic units. In all three populations, auxiliary data was available to show that detection probability of aboveground plants was m 0.995</span><br><span></span></p><p><span>We fitted multistate models in program MARK by specifying three states (D, V, F), even though the dormant state D does not occur in the encounter histories. Detection probability is fixed at 1 for the vegetative (V) and the flowering state (F) and at zero for the dormant state (D). Rates of survival and of state transitions as well as slopes of covariate relationships can be estimated and LRT or the AIC machinery be used to select among models. To estimate the fraction of the population in the unobservable</span><br><span>dormant state, the encounter histories are collapsed to 0 (plant not observed aboveground) and 1 (plant observed aboveground). The Cormack–Jolly–Seber model without constraints on detection probability is used to estimate detection probability, the complement of which is the estimated fraction of the population in the dormant state.</span><br><span>Parameter identifiability is an important issue in multi state models. We used the Catchpole–Morgan–Freeman approach to determine which parameters are estimable in principle in our multi state models. Most of 15 tested models were indeed estimable with the notable exception of the most general model, which has fully interactive state- and time-dependent survival and state transition rates. This model would become identifiable if at least some plants would be excavated in years when they do not show up aboveground.</span><br><span></span></p><p><span>Our analyses for three analyzed populations of Cleistes and Cypripedium yielded annual ramet survival rates ranging from 0.86–0.96. Estimates of the average fraction dormant ranged from 0.02–0.30, but with up to half a population in the dormant state in some years. Ultrastructural modeling enables interesting hypotheses to be tested about the relationships of demographic rates with climatic covariates for instance. Such covariate modeling makes the CR approach particularly interesting for evolutionary–ecological questions about, e.g., the adaptive significance of the dormant state.</span></p>","language":"English","publisher":"Museu de Ciencies Naturals de Barcelona","usgsCitation":"Kery, M., and Gregg, K., 2004, Demographic estimation methods for plants with dormancy: Animal Biodiversity and Conservation, v. 27, no. 1, p. 129-131.","productDescription":"3 p.","startPage":"129","endPage":"131","numberOfPages":"3","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":196030,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":330502,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://abc.museucienciesjournals.cat/volum-27-1-2004-abc/demographic-estimation-methods-for-plants-with-dormancy/?lang=en"}],"volume":"27","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fee4b07f02db5f7541","contributors":{"authors":[{"text":"Kery, M.","contributorId":46637,"corporation":false,"usgs":true,"family":"Kery","given":"M.","affiliations":[],"preferred":false,"id":341657,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gregg, K.B.","contributorId":34224,"corporation":false,"usgs":true,"family":"Gregg","given":"K.B.","email":"","affiliations":[],"preferred":false,"id":341656,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Fifty-three birds banded in previous years were captured, all of species that either nest or. winter here. Included were a record high 16 Gray Catbirds, nine of which were hatching-year (HY) birds when banded. Six return Red-eyed Vireos were captured, again far fewer than during the station's first 20 years of operation; the oldest, an adult when banded in Aug 1998, was last captured in Aug 2000.

With three stations reporting their worst year ever, we really need to be refreshed. After a cool and wet July, August was hot and wet in the east. Temperatures in September remained close to normal, but thanks to tropical storms Henri (6-8 Sep) and Isabel (18 Sep), rainfall was excessive in the Chesapeake Bay states. The entire Northeast had cool weather in October, starting with an early freeze on 3 Oct that triggered some good banding days in our region. Precipitation was unusually spotty in October, but plentiful at most of the Region IV stations. November temperatures were consistently well above the norm, starting with a record-breaking 81 ø in Baltimore on the 1<sup>st</sup>.</p><p>Four of the five Maryland stations had their best day on 19 or 20 Oct. One might expect some of the Virginia coastal stations, Chincoteague, Kiptopeke, and Back Bay, to share the same best day, but they did not. Three stations reported an increase in birds per net hour this year, while seven had a decline. Summarizing the changes in rank in Table 2, Gray Catbird was the species with the most (5) increases in rank (in excess of decreases), followed by junco (4) and Myrtle Warbler and Swamp Sparrow (3 each). Yellowthroat had the most decreases (5), followed by redstart (3).</p><p>Myrtle Warbler (4572) was once again the most commonly banded species in Region IV, followed by White-throated Sparrow (1723), Gray Catbird (1349), and Western Palm Warbler (1090). Michelle Davis' station on Key Biscayne is the envy of the rest of us. Her top eight species were all warblers and there was not a Myrtle among them. Imagine having Parula, Prairie, and Worm-eating warblers fighting for sixth place!</p><p>Not showing among the top ten, however, are other surprises. Several banders commented on Sawwhet Owls and Bicknell's Thrushes. Deanna Dawson banded a Cerulean Warbler at Patuxent. Danny Bystrak caught 138 Swamp Sparrows at Jug Bay. In addition to two Clay-colored Sparrows and two Gambel's White-crowns, Jim Gruber at Chino Farms had his first Le Conte's Sparrow and a state high of 39 Lincoln's Sparrows. Dick Roberts' new species at Chincoteague included Yellow-throated and Mourning warblers, while Jethro Runco's best birds at Kiptopeke included S edge Wren and Golden-winged Warbler. The Simpsons at Back Bay finally identified a Western Wood-Pewee after many years of trying. Unusual for Michelle Davis' warbler station on Key Biscayne were Tennessee, Chestnut-sided, and Bay-breasted warblers. </p>","language":"English","publisher":"Western, Inland, and Eastern Bird Banding Associations","usgsCitation":"Robbins, C.S., 2004, Atlantic Flyway review: Region IV - Fall 2003: North American Bird Bander, v. 29, no. 3, p. 124-131.","productDescription":"8 p.","startPage":"124","endPage":"131","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":337258,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://www.westernbirdbanding.org/nabb.html","text":"Journal's Website"},{"id":197888,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"29","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaee4b07f02db66c816","contributors":{"authors":[{"text":"Robbins, Chandler S. crobbins@usgs.gov","contributorId":4275,"corporation":false,"usgs":true,"family":"Robbins","given":"Chandler","email":"crobbins@usgs.gov","middleInitial":"S.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":341622,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Cumulative unionid mortality ranged from 13 to 93% among sites, and was associated with low flow velocity (below 0.01 m/s) and dissolved oxygen concentrations below 5 mg/L.  Species assemblages demonstrated differential mortality under declining dissolved oxygen conditions.  Riffle and medium-large stream mussel assemblages had greater mortality than generalist assemblages under reduced dissoloved oxygen (DO < 5 mg/L).  Mussel community composition at medium-sized sites shifted toward greater dominance of generalist species and lower proportions of riffle and medium-large stream species.  At other sites, community structure changed little, likely due to the dominance of drought-resilient species in small streams and less detrimental changes in stream habitat conditions in large streams.  Low flow conditions and severe drought adversely affected mussel distributions and assemblages, particularly in high diversity, medium-sized streams.","language":"English","publisher":"Taylor &

Along with 793 individual birds (107 species and six additional genera), we found seven mammals and nine insects. In addition, two nestling peregrines were consumed. We found a larger dependence upon White-throated Swifts (<i>Aeronautes saxatalis</i>) and birds on migration in northern Arizona, while in southeastern and central Arizona average prey mass was greater and columbiforms formed the largest dietary component. In northern, central, and southeastern Arizona, 74, 66, and 56 avian prey taxa, respectively, were recorded. We used capture-recapture modeling to estimate totals of <span>111 ± 9.5, 113 ± 10.5, and 86 ± 7.9</span> (SE) avian taxa taken in these same three areas. These values are counterintuitive inasmuch as the southeast has the richest avifauna. For the entire study area, <span>156 ± 9.3</span> avian taxa were estimated to be taken by peregrines.</p>","language":"English","publisher":"Oxford

Traditional methods include the assumptions that (1) each state an animal occupies is observable, and (2) state is assigned correctly at each point in time.  Failure of either of these assumptions can lead to biased estimates of demographic parameters.  I review design and analysis options for minimizing or eliminating these biases.  Unobservable states can be adjusted for by including them in the state space of the statistical model, with zero capture probability, and incorporating the robust design, or observing animals in the unobservable state through telemetry, tag recoveries, or incidental observations.  Mis-classification can be adjusted for by auxiliary data or incorporating the robust design, in order to estimate the probability of detecting the state an animal occupies.  For both unobservable and mis-classified states, the key feature of the robust design is the assumption that the state of the animal is static for at least two sampling occasions.","language":"English","publisher":"Museu de Ciencies Naturals de Barcelona","usgsCitation":"Kendall, W., 2004, Coping with unobservable and mis-classified states in capture-recapture studies: Animal Biodiversity and Conservation, v. 27, no. 1, p. 97-107.","productDescription":"11 p.","startPage":"97","endPage":"107","numberOfPages":"11","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201915,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17605,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://abc.museucienciesjournals.cat/volum-27-1-2004-abc/coping-with-unobservable-and-mis-classified-states-in-capture-recapture-studies/?lang=en","linkFileType":{"id":5,"text":"html"}}],"volume":"27","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad8e4b07f02db6848af","contributors":{"authors":[{"text":"Kendall, W.

We investigated the response of the faunal community of a small microtidal estuary dominated by Ruppia maritima (widgeon grass) in Maine, United States, to increased nitrogen loading using an in situ mesocosm enrichment experiment.  Community response was characterized by assessing quantitative shifts in macroin-vertebrate community composition and identifying changes in food web structure using stable carbon and nitrogen isotope ratios of producers and consumers.  The community was dominated by brackish water invertebrates including midge larvae, oligochaetes, damselfly larvae, amphipods, and ostracods.  Experimental nutrient additions resulted in significantly lower densities of herbivorous chironomids and predatory damselflies and greater densities of deposit feeding oligochaetes.  Grazing midge larvae (Chironomidae: Dicrotendipes, Cricotopus) consumed epiphytic algae under both natural and enriched conditions.  Deposit feeding Chironomus was dependent on allochthonous sources of detritus under natural conditions and exhibited a shift to autochthonous sources of detritus under enriched conditions.

Despite the important role of individual heterogeneity in vital rates in demography, population dynamics and life history theory, the idea of 'individual quality' is elusive. It is sometimes assumed to be a static or dynamic individual characteristic. When considered as a dynamic trait, it is sometimes assumed to vary deterministically or stochastically, or to be confounded with the characteristics of the habitat. We addressed heterogeneity in reproductive performance among individuals established in higher-quality habitat in a long-lived seabird species. We used approaches to statistical inference based on individual random effects permitting quantification of heterogeneity in populations and assessment of individual variation from the population mean. We found evidence of heterogeneity in breeding probability, not success probability. We assessed the influence of dispersal on individual reproductive potential. Dispersal is likely to be destabilizing in species with high site and mate fidelity. We detected heterogeneity after dispersal, not before. Individuals may perform well regardless of quality before destabilization, including those that recruited in higher-quality habitat by chance, but only higher-quality individuals may be able to overcome the consequences of dispersal. Importantly, results differed when accounting for individual heterogeneity (an increase in mean breeding probability when individuals dispersed), or not (a decrease in mean breeding probability). In the latter case, the decrease in mean breeding probability may result from a substantial decrease in breeding probability in a few individuals and a slight increase in others. In other words, the pattern observed at the population mean level may not reflect what happens in the majority of individuals.","language":"English","publisher":"Wiley","doi":"10.1111/j.0030-1299.2003.13097.x","usgsCitation":"Cam, E., Monnat, J.#., and Royle, J., 2004, Dispersal and individual quality in a long lived species: Oikos, v. 106, no. 2, p. 386-398, https://doi.org/10.1111/j.0030-1299.2003.13097.x.","productDescription":"13 p.","startPage":"386","endPage":"398","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202449,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"106","issue":"2","noUsgsAuthors":false,"publicationDate":"2004-07-05","publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db62595b","contributors":{"authors":[{"text":"Cam, E.","contributorId":12952,"corporation":false,"usgs":true,"family":"Cam","given":"E.","affiliations":[],"preferred":false,"id":341386,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Monnat, J. #NAME?","contributorId":33019,"corporation":false,"usgs":true,"family":"Monnat","given":"J.","email":"","middleInitial":"#NAME?","affiliations":[],"preferred":false,"id":341387,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Royle, J.

Fifty-nine females were radiomarked and tracked during 1997 through 2000 in Irondequoit, New York, USA, a suburb of Rochester. We constructed home ranges for those deer with A greater than or equal to 18 reclocations/season. Fifty percent minimum convex polygons (MCP) averaged 3.9 (SE = 0.53) ha in the summer and 5.3 (SE = 0.80) ha in the winter. Deer showed strong fidelity to both summer and winter home ranges, and 30 of 31 females showed overlap of summer and winter home ranges. Annual survival was 64%; the major cause of mortality was deer-automobile collisions. Average annual dispersal rates were &lt;15% for yearlings and adults. Using matrix population modeling, we explored the role of female dispersal in sustaining different management objectives in adjacent locales of approximately 1,000 ha. Modeling showed that if female dispersal was 8%, culling would have to reduce annual survival to 58% to maintain a population just under ecological carrying capacity and reduce survival to 42% to keel) the population at one-half carrying capacity. With the same dispersal, contraception Would need to be effective in 32% of females if the population is near carrying capacity and 68% if the population is at one-half of carrying capacity. Movement behavior data and modeling results lend support to the use of a localized approach to management of females that emphasizes neighborhood-scale manipulation of deer populations, but our research suggests that dispersal rates in females could be critical to long-term success.</p>","language":"English","publisher":"BioOne Complete","doi":"10.2193/0022-541X(2004)068[0247:MBDATP]2.0.CO;2","usgsCitation":"Porter, W., Underwood, H., and Woodard, J., 2004, Movement behavior, dispersal, and the potential for localized management of deer in a suburban environment: Journal of Wildlife Management, v. 68, no. 2, p. 247-256, https://doi.org/10.2193/0022-541X(2004)068[0247:MBDATP]2.0.CO;2.","productDescription":"10 p.","startPage":"247","endPage":"256","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201912,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"New York","county":"Monroe County","city":"Irondequoit","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -77.60467529296875,\n              43.206176810164784\n            ],\n            [\n              -77.5360107421875,\n              43.206176810164784\n            ],\n            [\n              -77.5360107421875,\n              43.248203680382346\n            ],\n            [\n              -77.60467529296875,\n              43.248203680382346\n            ],\n            [\n              -77.60467529296875,\n              43.206176810164784\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"68","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6fe4b07f02db640e29","contributors":{"authors":[{"text":"Porter, W.F.","contributorId":81597,"corporation":false,"usgs":true,"family":"Porter","given":"W.F.","email":"","affiliations":[],"preferred":false,"id":341398,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Underwood, H.B. 0000-0002-2064-9128","orcid":"https://orcid.org/0000-0002-2064-9128","contributorId":90849,"corporation":false,"usgs":true,"family":"Underwood","given":"H.B.","affiliations":[],"preferred":false,"id":341399,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Woodard, J.L.","contributorId":36263,"corporation":false,"usgs":true,"family":"Woodard","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":341397,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The quality of sediments from five impoundments (impoundments no. 1, 2, 6, 7, and 17) on the NWR was evaluated using physical and chemical characterization, contaminant concentrations (metals, organochlorine pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons), and toxicity testing. Survival of <i>Hyalella azteca</i> (freshwater amphipod) exposed for 28 days to solid-phase sediments was not significantly different from controls, but growth was significantly decreased at several sites. Survival in 96-hour exposures to sediment pore water was significantly decreased at most sites. Factors contributing to the toxic responses were low pH (3.7 to 4.1), ammonia (20 mg/L), and increased concentrations of cations in the pore water. The excess of simultaneously extracted metals over the acid volatile sulfides in the sediments was also typical of sites displaying decreased sediment quality. Elemental concentrations in pore water were negatively correlated with pH, and the highest concentrations were observed in impoundment no. 7. The acidic nature of the sediment in this impoundment was exacerbated by recent draining, burning, and disking, which allowed oxidation of the previously anoxic wetland sediment. Sediment disturbance and mixing of vegetation into the sediments by disking may also have contributed to the formation of ammonia caused by microbial decomposition of the fragmented organic matter. Contaminants were not detected in sediments from the impoundments, but releases of acidic water with increased levels of sediment cations from the impoundments may have contributed to the degraded sediment conditions previously observed in the river. The practice of dewatering sediments for vegetation control may exacerbate the acidification of vulnerable sediments within impoundments of this NWR.</p>","language":"English","publisher":"SpringerLink","doi":"10.1007/S00244-004-3088-Z","usgsCitation":"Winger, P.V., and Lasier, P., 2004, Sediment quality in freshwater impoundments at Savannah National Wildlife Refuge: Archives of Environmental Contamination and Toxicology, v. 47, no. 3, p. 304-313, https://doi.org/10.1007/S00244-004-3088-Z.","productDescription":"10 p.","startPage":"304","endPage":"313","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202089,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Georgia","otherGeospatial":"Savannah National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.17042541503906,\n              32.1134038780317\n            ],\n            [\n              -81.07017517089842,\n              32.1134038780317\n            ],\n            [\n              -81.07017517089842,\n              32.23603621746476\n            ],\n            [\n              -81.17042541503906,\n              32.23603621746476\n            ],\n            [\n              -81.17042541503906,\n              32.1134038780317\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"47","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0be4b07f02db5fbfb5","contributors":{"authors":[{"text":"Winger, P.

Currently &gt;250,000 ha of marginal farmland have been returned to hardwood forests. I observed establishment of trees and shrubs on 205 reforested bottomlands: 133 sites were planted primarily with oak species (</span><i>Quercus</i><span>&nbsp;spp</span><i>.</i><span>), 60 sites were planted with pulpwood producing species (</span><i>Populus deltoides</i><span>,&nbsp;</span><i>Liquidambar styraciflua</i><span>, or&nbsp;</span><i>Platanus occidentalis</i><span>), and 12 sites were not planted (i.e., passive regeneration). Although oak sites were planted with more species, sites planted with pulpwood species were more rapidly colonized by additional species. The density of naturally colonizing species exceeded that of planted species but density of invaders decreased rapidly with distance from forest edge. Trees were shorter in height on sites planted with oaks than on sites planted with pulpwood species but within a site, planted trees attained greater heights than did colonizing species. Thus, planted trees dominated the canopy of reforested sites as they matured. Planted species acted in concert with natural invasion to influence the current condition of woody vegetation on reforested sites. Cluster analysis of species importance values distinguished three woody vegetation conditions: (1)&nbsp;</span><i>Populus deltoides</i><span>&nbsp;stands (2) oak stands with little natural invasion by other tree species, and (3) stands dominated by planted or naturally invading species other than oaks. Increased diversity on reforested sites would likely result from (a) greater diversity of planted species, particularly when sites are far from existing forest edges and (b) thinning of planted trees as they attain closed canopies.</span></p>","language":"English","publisher":"SpringerLink","doi":"10.1023/B:VEGE.0000026344.29613.4a","usgsCitation":"Twedt, D., 2004, Stand development on reforested bottomlands in the Mississippi Alluvial Valley: Plant Ecology, v. 172, no. 2, p. 251-263, https://doi.org/10.1023/B:VEGE.0000026344.29613.4a.","productDescription":"13 p.","startPage":"251","endPage":"263","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203154,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arkansas, Kentucky, Louisiana, Mississippi, Missouri, Tennessee","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.0537109375,\n              39.36827914916014\n            ],\n            [\n              -94.7900390625,\n              38.20365531807149\n            ],\n            [\n              -94.52636718749999,\n              35.35321610123823\n            ],\n            [\n              -93.955078125,\n              29.726222319395504\n            ],\n            [\n              -89.82421875,\n              29.11377539511439\n            ],\n            [\n              -89.29687499999999,\n              29.99300228455108\n            ],\n            [\n              -87.62695312499999,\n              30.06909396443887\n            ],\n            [\n              -85.166015625,\n              30.826780904779774\n            ],\n            [\n              -84.90234374999999,\n              32.24997445586331\n            ],\n            [\n              -85.6494140625,\n              34.74161249883172\n            ],\n            [\n              -81.82617187499997,\n              37.47485808497102\n            ],\n            [\n              -82.265625,\n              37.96152331396614\n            ],\n            [\n              -82.30957031249999,\n              38.54816542304656\n            ],\n            [\n              -84.638671875,\n              39.027718840211605\n            ],\n            [\n              -85.86914062499999,\n              38.13455657705411\n            ],\n            [\n              -88.11035156249999,\n              37.71859032558816\n            ],\n            [\n              -88.90136718749999,\n              37.125286284966805\n            ],\n            [\n              -89.86816406249999,\n              36.31512514748051\n            ],\n            [\n              -89.4287109375,\n              37.19533058280065\n            ],\n            [\n              -90.3515625,\n              38.92522904714054\n            ],\n            [\n              -91.7138671875,\n              40.68063802521456\n            ],\n            [\n              -95.5810546875,\n              40.51379915504413\n            ],\n            [\n              -95.0537109375,\n              39.36827914916014\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"172","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e1e4b07f02db5e47ff","contributors":{"authors":[{"text":"Twedt, D.J. 0000-0003-1223-5045","orcid":"https://orcid.org/0000-0003-1223-5045","contributorId":105009,"corporation":false,"usgs":true,"family":"Twedt","given":"D.J.","affiliations":[],"preferred":false,"id":341396,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

It is a 65-ha Waterfowl Production Area with numerous temporary, seasonal, and semi-permanent wetlands.  Ground water and surface water have been monitored at the site from 1987 to 1989 and from 1993 to the present.  Vegetation has been monitored since 1993.  The monitoring record includes two nearly back-to-back weather extremes: a drought in the late 1980s and a deluge in the early- to mid-1990s.  Wetlands differed sharply in water levels between 3-yr dry and wet periods.  For example, the time of inundation ranged among semi-permanent wetlands from 13 to 71 percent during the dry years to 100 percent during the wet years, while for seasonal wetlands, it was 0-29 percent and 46-100 percent, respectively, during dry and wet periods.  Temporary wetlands had no surface water during the dry period but had standing water 0-67 percent of the time during the deluge years.  The highest ground-water levels during the dry period were lower than most levels during the wet period.  The difference in the water-table elevations of temporary wetlands between the periods was as much as 4 m.  Ground-water levels near semi-permanent wetlands were considerably more stable (annual range of 0.3-1.6 m) than those near temporary wetlands (1.3-2.5 m).  The results support the concept that weather extremes drive the wetland cover cycle and other key ecological processes in prairie wetlands.  The new data from Orchid Meadows, together with other long-term data sets from North Dakota and Saskatchewan, Canada, are useful for many research purposes, including the parameterization and testing of models that simulate the effects of climate variability and climate change on prairie wetland ecosystems.

(1992) and Hamel (1992), such concern prompted the U.S. Department of the Interior, Fish and Wildlife Service (USFWS) to commission a status assessment of the Cerulean Warbler (Hamel 2000a). Shortly after the status review was published, a petition (Ruley 2000) was delivered to the USFWS urging that the species be listed as “threatened” under the Endangered Species Act of 1973. The account of the Cerulean Warbler in the Birds of North America series also appeared that year (Hamel 2000b). Substantial attention is currently focused on the species, and the Cerulean Warbler Technical Group (CWTG) was formed in 2002 (see Appendix).</p><p>This overview consists of two parts.
