The numerical model being used is a hybrid version of the Blumberg and Mellor ECOM3D model, modified to include a semi-implicit time-stepping scheme and transport of a non-reactive dissolved constituent. Tides in the bays are dominated by the semi-diurnal frequencies, in particular by the M2 tide, due to the resonance of these frequencies in the Gulf of Maine. The numerical model reproduces, well, measured tidal ellipses in unstratified wintertime conditions. Stratified conditions present more of a problem because tidal-frequency internal wave generation and propagation significantly complicates the structure of the resulting tidal field. Nonetheless, the numerical model reproduces qualitative aspects of the stratified tidal flow that are consistent with observations in the bays.","largerWorkTitle":"Proceedings - National Conference on Hydraulic Engineering","conferenceTitle":"Proceedings of the National Conference on Hydraulic Engineering","conferenceDate":"July 25-30, 1993","conferenceLocation":"San Francisco, CA, USA","language":"English","publisher":"ASCE","publisherLocation":"New York, NY, United States","isbn":"0872629201","usgsCitation":"Jenter, H., Signell, R.P., and Blumberg, A., 1993, Modeling the tides of Massachusetts and Cape Cod Bays, <i>in</i> Proceedings - National Conference on Hydraulic Engineering, no. pt 2, San Francisco, CA, USA, July 25-30, 1993, p. 2323-2332.","productDescription":"10 p.","startPage":"2323","endPage":"2332","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":228785,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.894775390625,\n              41.713930073371294\n            ],\n            [\n              -69.949951171875,\n              41.713930073371294\n            ],\n            [\n              -69.949951171875,\n              42.68647341541784\n            ],\n            [\n              -70.894775390625,\n              42.68647341541784\n            ],\n            [\n              -70.894775390625,\n              41.713930073371294\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","issue":"pt 2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5c53e4b0c8380cd6fbd8","contributors":{"editors":[{"text":"Shen Hsieh WenSu S.T.Wen Feng","contributorId":128306,"corporation":true,"usgs":false,"organization":"Shen Hsieh WenSu S.T.Wen Feng","id":536409,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Jenter, H.

A shoreface sandstone occurs in the lower part of the Mesaverde Formation at all localities studied, and is directly overlain by a coaly interval. Repetitive coarsening-upward cycles of mudstone, siltstone, and sandstone occur in the 200 ft interval of the upper part of the Cody Shale below the shoreface sandstone. These Cody sandstones are typically hummocky cross stratified with symmetrical ripples near the top, indicating that they are largely storm surge deposits that were later reworked. Channel-form sandstones from 10 to 20 ft thick, with abundant locally derived clayey clasts, occur in a 75 ft thick interval below the shoreface at one locality. These unusual sandstones are largely confined to a narrow area of the outcrop and grade laterally into more typical storm surge deposits. They may be unusually large storm surge channels created when high-energy flow conditions were localized to a limited area of the shelf.</p><p class=\"indent\">The Mesaverde Formation above the shoreface sandstone is divided into a middle member and the Teapot Sandstone Member. The lower part of the middle member is everywhere coaly. Erosional-based sandstones in this coaly interval are highly variable in thickness and architecture. Thin, single channel sandstone bodies were deposited by moderate to high sinuosity streams, and thick, multistory channel sandstone bodies were deposited by rapidly switching fluvial channel systems that remained relatively stationary for extended periods of time. The architecture of the fluvial channel sandstones in the overlying noncoaly interval appears to be highly variable as well, with complex multistory sandstones occurring at different stratigraphic levels at different localities. This distribution may be explained by long term stability of fluvial channel systems followed by major avulsion events.</p><p class=\"indent\">The Teapot Sandstone Member consists of fairly persistent to lenticular white multistory sandstone units that are as much as 85 ft thick and contain trough cross beds as much as 5 ft high. These sandstone units are interbedded with gray mudstones and carbonaceous shales. Paleosols are preserved at the tops of individual sandstones in the multistory units in some places. It is suggested that these sandstones were deposited largely by low-sinuosity to braided streams. The Meeteetse Formation consists of alternating coal and sandstone-rich intervals. The coal-rich intervals have relatively thin fluvial channel sandstones probably deposited by medium to high sinuosity streams whereas the sand-rich intervals have thick (to 105 ft) multistory fluvial channel sandstones possibly deposited by low-sinousity to braided streams.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Oil and Gas and Other Resources of the Wind River Basin, Wyoming; Special Symposium","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"Wyo.

We found that agricultural return flow drains and a municipal wastewater treatment plant were the largest sources of nutrients to the river during low river flow. The Sutter and Colusa agricultural drains contributed about 70% of the transport of DIN and DRP by the river above Sacramento (about 20% of the total transport by the river) between August 8 and September 26, 1985. Further downstream, the Sacramento Regional Wastewater Treatment Plant discharged DIN and DRP at rates that were roughly 70% of total DIN and DRP transport by the river at that time. Concentrations at Rio Vista on the tidal river below the Sacramento plant and at the head of the estuary were related to the reciprocals of the river flows, indicating the importance of dilution of the Sacramento waste by river flows. During very dry years, elevated DIN and DRP concentrations were observed in Suisun Bay. We used a steady-state, one-dimensional, single-compartment box model of the bay, incorporating terms for advection, exchange, and waste input, to calculate a residual rate for all processes not included in the model.

Because of the long time scales inherent in such a lake management manipulation, it became imperative to attempt to predict how the lake would respond to changes in planktivorous fish abundance over time scales of several decades. We know from the past 15 years of study (Lathrop and Carpenter, Ch. 7 and 8; Magnuson and Lathrop, Ch. 11) that substantial variation of planktivorous fish, zooplankton, and phytoplankton abundances can occur the lake. Given the current stocking of piscivores, we have the potential to substantially modify the abundance of planktivorous fish and possibly shift the assemblages of phytoplankton and zooplankton beyond the ranges of those which occurred previously.

It attaches to hard substrates, forming layers, occluding water intakes, encrusting and killing native mussels, filtering algae in competition with other planktivores, and possibly interfering with fish spawning.  It reproduces prolifically, suggesting that an approach to its control may be by controlling its reproduction.  Previous literature suggests that spawning in bivalves is regulated by both environmental and internal chemical cues.  A suggested sequence is that phytoplankton chemicals initially trigger spawning; chemicals associated with gametes provide a species-specific pheromonal positive feedback for spawning; and the response to environmental chemicals is mediated internally by serotonin (5-HT).  The role of 5-HT in zebra mussels is under investigation. Both males and females can be induced to spawn by either injection or external application of 5-HT.  The response can also be activated by 8-hydroxy-2-(di-n-propylamino)-tetralin, an agonist at 5-HT<sub>1A</sub> receptors.  HPLC analysis has detected 5-HT as the major biogenic amine in both male and female gonads.  5-HT immunocytochemistry demonstrates nerves containing serotonergic fibers innervating gonads of both males and females, with prominent varicosities surrounding the follicles in both sexes.  A role of 5-HT in mediating spawning responses in zebra mussels is thus strongly supported.  These studies have shown that reproductive behavior of zebra mussels can be modified by outside chemicals, a property that may be exploited for purposes of control.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Invertebrate Reproduction and Development","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"Philadelphia, PA","doi":"10.1080/07924259.1992.9672259","collaboration":"Abstract has subscript/superscript to be fixed","usgsCitation":"Ram, J.L., Fong, P., Croll, R.P., Nichols, S., and Wall, D., 1992, The zebra mussel (Dreissena polymorpha), a new pest in North America: reproductive mechanisms as possible targets of control strategies: Invertebrate Reproduction and Development, v. 22, no. 1-3, p. 77-86, https://doi.org/10.1080/07924259.1992.9672259.","productDescription":"10 p.","startPage":"77","endPage":"86","numberOfPages":"9","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":259727,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259726,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/07924259.1992.9672259","linkFileType":{"id":5,"text":"html"}}],"otherGeospatial":"North America","volume":"22","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb1ece4b08c986b3254b9","contributors":{"authors":[{"text":"Ram, Jeffrey L.","contributorId":33659,"corporation":false,"usgs":true,"family":"Ram","given":"Jeffrey","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":354619,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fong, Peter","contributorId":94149,"corporation":false,"usgs":true,"family":"Fong","given":"Peter","email":"","affiliations":[],"preferred":false,"id":354622,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Croll, Roger P.","contributorId":83784,"corporation":false,"usgs":true,"family":"Croll","given":"Roger","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":354621,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nichols, Susan J.","contributorId":48905,"corporation":false,"usgs":true,"family":"Nichols","given":"Susan J.","affiliations":[],"preferred":false,"id":354620,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wall, Darcie","contributorId":94909,"corporation":false,"usgs":true,"family":"Wall","given":"Darcie","email":"","affiliations":[],"preferred":false,"id":354623,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Overall, tufted puffins consumed (by weight) 41% sandlance (Ammodytes hexapterus), 22% capelin (Mallotus villosus), 19% walleye pollock (Theragra chalcogramma), 13% other fish, and 5% invertebrates, whereas horned puffins took 85% sandlance, 4% capelin, 2% pollock, 8% other fish, and <1 % invertebrates. All of the pollock consumed were young of the year, whereas 4 year-classes of capelin were present, from young of the year through spawning adults. Puffins took mostly first-year sandlance, but fish in their second year or older were also common at colonies near Kodiak, Alaska. The importance of juvenile pollock in the diet of tufted puffins varied geographically from little or no use in the north-central Gulf and Kodiak areas to moderate use (5 to 20%) in the Semidi and Shumagin Islands to heavy use (25 to 75%) in the Sandman Reefs and eastern Aleutians. An estimated 11 billion pollock were consumed by tufted puffins throughout the region in 1986. The proportion of pollock in puffin diets at the Semidi Islands was strongly correlated with independent estimates of cohort strength in 3 years. Puffins may thus provide a useful index of distribution and year class abundance of first-year pollock, a species that currently supports an important commercial fishery in the Gulf of Alaska.","language":"English","publisher":"Inter-Research Science Publisher","doi":"10.3354/meps080001","usgsCitation":"Hatch, S., and Sanger, G.A., 1992, Puffins as samplers of juvenile pollock and other forage fish in the Gulf of Alaska: Marine Ecology Progress Series, v. 80, p. 1-14, https://doi.org/10.3354/meps080001.","productDescription":"14 p.","startPage":"1","endPage":"14","numberOfPages":"14","costCenters":[{"id":106,"text":"Alaska Biological Science Center","active":false,"usgs":true}],"links":[{"id":488001,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps080001","text":"Publisher Index Page"},{"id":259710,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Gulf Of Alaska","volume":"80","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9020e4b0c8380cd7fb4d","contributors":{"authors":[{"text":"Hatch, Scott","contributorId":16268,"corporation":false,"usgs":true,"family":"Hatch","given":"Scott","affiliations":[],"preferred":false,"id":355628,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sanger, Gerald A.","contributorId":10660,"corporation":false,"usgs":true,"family":"Sanger","given":"Gerald","email":"","middleInitial":"A.","affiliations":[{"id":6654,"text":"USFWS","active":true,"usgs":false}],"preferred":false,"id":355627,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Little is understood of the physiological consequences to embryo-larval fishes of prolonged exposure to soft, acidic waters; however, dysfunction of respiratory and ionoregulatory processes is suspected. In order to evaluate the effects of acid exposure on the respiratory and ionoregulatory systems of developing brook trout, Salvelinus fontinalis, differences in gill morphology and numbers of chloride cells were compared between groups cf developing embryo-larval fish continuously exposed to moderately hard well water (130.0 mg.l<sup>-1</sup> as CaCO<sub>3</sub>, pH 7.94) or to reconstituted soft, acidic water (4.4 mg.l<sup>-1</sup> as CaCO<sub>3</sub>, pH 5.25) designed to mimic acidic waters of northern Wisconsin acidified lakes. Exposures were maintained for up to 48 days (82 days after fertilization) during critical periods of growth and differentiation of branchial structures. The second right gill arch of each fish was examined for changes in the development of filaments and lamellae and for differences in numbers of chloride cells. Gills of fish that developed in soft, acidic water contained greater numbers of normal and degenerating chloride cells, exhibited hyperplasia of primary epithelium and multiple fusions of adjacent filaments and lamellar epithelium than the gills of control fish. Filament and lamellar lengths and numbers of lamellae per filament were significantly less (<i>P</i>< 0.05) in fish that developed in soft, acidic water than in fish exposed to well water.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Aquatic Toxicology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0166-445X(92)90034-K","collaboration":"Abstract has subscript/superscript to be fixed","usgsCitation":"Conklin, D., Mowbray, R., and Gingerich, W., 1992, Effects of chronic exposure to soft, acidic water on gill development and chloride cell numbers in embryo-larval brook trout, Salvelinus fontinalis: Aquatic Toxicology, v. 22, no. 1, p. 39-52, https://doi.org/10.1016/0166-445X(92)90034-K.","productDescription":"14 p.","startPage":"39","endPage":"52","numberOfPages":"14","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":259874,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259826,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0166-445X(92)90034-K","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Wisconsin","volume":"22","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a06ace4b0c8380cd51376","contributors":{"authors":[{"text":"Conklin, D.J.","contributorId":24216,"corporation":false,"usgs":true,"family":"Conklin","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":355179,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mowbray, R.C.","contributorId":64084,"corporation":false,"usgs":true,"family":"Mowbray","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":355180,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gingerich, W.H.","contributorId":83481,"corporation":false,"usgs":true,"family":"Gingerich","given":"W.H.","email":"","affiliations":[],"preferred":false,"id":355181,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Masses of breast and leg muscle protein were greatest in adult males and lowest in immature males, but similar in adult and immature females. Fat and protein levels in late-wintering ruddy ducks were independent of their body size. We detected no differences among sex-age classes in the proportion of animal foods consumed. Aquatic invertebrates composed 85% of the diet; midge larvae (Diptera: Chironomidae) and brine flies (Diptera: Ephydridae) were the principal taxa consumed. Molt score by feather region and overall molt score did not vary by sex or age. Light to moderate molt (25 to 50% molting feathers) was recorded in all feather regions.

Both parametric and nonparametric methods to estimate survival have becn developed or modified from other applications. An implicit assumption in these approaches is that the probability of re-locating an animal with a functioning transmitter is one. A Monte Carlo study was conducted to determine the bias and variance of the Kaplan-Meier estimator and an estimator based also on the assumption of constant hazard and to eva!uate the performance of the two-sample tests associated with each. Modifications of each estimator which allow a re-Iocation probability of less than one are described and evaluated. Generallv the unmodified estimators were biased but had lower variance. At low sample sizes all estimators performed poorly. Under the null hypothesis, the distribution of all test statistics reasonably approximated the null distribution when survival was low but not when it was high.

The chemical composition was determined by microprobe for 16 elements from a polished thin section. Three analyses were made per millimeter and averaged to give the composition of each millimeter. The age of the crust was determined by measuring the strontium isotope composition of the crust and comparing it with the Tertiary seawater curve. The crust represents 18.5 m.y. of growth of Fe and Mn oxyhydroxides. The crust is composed of alternating botryoidal and laminated layers. The botryoidal layers formed during the same time intervals that widespread Neogene deep-sea hiatuses were forming in bottom sediments. The botryoidal layers represent growth during times of intensified deepwater flow, whereas the laminated intervals represent more quiescent conditions. The correspondence between the botryoidal layers and the Neogene hiatuses is so strong that we were able to choose a variable growth rate model over a constant growth rate model for the crust. Chemical changes in the crust take two forms. The first is represented by broad changes in the composition defined chiefly by fourth-order polynomial fits to the chemical profiles of each element with depth in the crust. The second is high-frequency changes in composition. The broader changes occurred primarily at about 15, 11.5, 7.4, 6.4, 5.2, and 4.6 Ma, which may correlate with major changes in paleoceanographic circulation and development of ice caps at the poles. The periods of the high-frequency changes may reflect climatic changes that resulted from orbital forcing. These high-frequency changes may correspond to the high-order eccentricity periods of 3.47, 2.04, and 1.31 m.y.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/91PA02936","issn":"08838305","usgsCitation":"Hein, J., Bohrson, W., Schulz, M.S., Noble, M., and Clague, D., 1992, Variations in the fine-scale composition of a central Pacific ferromanganese crust: Paleoceanographic implications: Paleoceanography and Paleoclimatology, v. 7, no. 1, p. 63-77, https://doi.org/10.1029/91PA02936.","productDescription":"15 p.","startPage":"63","endPage":"77","costCenters":[],"links":[{"id":224785,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-05-04","publicationStatus":"PW","scienceBaseUri":"505bc18fe4b08c986b32a646","contributors":{"authors":[{"text":"Hein, J.R. 0000-0002-5321-899X","orcid":"https://orcid.org/0000-0002-5321-899X","contributorId":61429,"corporation":false,"usgs":true,"family":"Hein","given":"J.R.","affiliations":[],"preferred":false,"id":375997,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bohrson, W.A.","contributorId":102092,"corporation":false,"usgs":false,"family":"Bohrson","given":"W.A.","affiliations":[],"preferred":false,"id":375998,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schulz, M.

Of 131 birds released through December 1990, 103 were reared by foster parents. The remaining 28 were experimentally hand-reared in 1989 and 1990. After refining release procedures, parent-reared birds have integrated into the wild flock, many have survived, and some have bred. Releases of hand-reared cranes elsewhere in the 1970's were largely unsuccessful, at least in part due to the lack of a lengthy acclimation period. A new hand-rearing protocol holds promise in producing release-worthy birds. The technique employs some features first used in the 1960's (e.g., a costume for the human caretaker and model crane heads used to train chicks to feed). In the mid-1980's, the following features were added: (1) the costumed caretaker was given a visor and feathers, (2) a taxidermic crane head or a hand puppet was held or suspended from the ceiling for use in stimulating chicks to feed, (3) a taxidermic mount of a brooding crane supplied warmth, (4) a full-sized live crane was maintained in an adjacent pen and in visual contact with neonatal young to provide an imprinting model, and (5) a small group of adult (or subadult) cranes was penned adjacent to the outdoor chick pens to provide socialization models. Recent releases of Mississippi sandhill cranes hand-reared according to this protocol and released in Mississippi have had high first-year survival rates. The now-operational technique holds promise for producing large numbers of release-worthy birds.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Sixth North American Crane Workshop.

Importantly, they breed more or less obligatorily in local clusters of colonies that can move regularly from site to site, and they routinely exchange breeders.  The properties of such metapopulations have only recently begun to be examined, often with models that are occupancy-based (using only colony presence or absence data) and deterministic (using single, empirically determined values for each of several population biology parameters).  Some recent models are now frequency-based (using actual population sizes at each site), as well as stochastic (randomly varying critical parameters between biologically realistic limits), yielding better estimates of the behavior of future populations. Using two such models designed to quantify relative risks of population changes under different future scenarios (RAMAS/stage and RAMAS/space), we have examined probable future populations dynamics for three hypothetical seabirds -- an albatross, a cormorant, and a tern.  With real parameters and ranges of values we alternatively modelled each species with and without density dependence, as well as with their numbers in a single, large colony, or in many smaller ones, distributed evenly or lognormally.  We produced a series of species-typical lines for different population risks over the 50 years we simulated. We call these curves Instantaneous Threat Assessments (ITAs), and their shapes mirror the varying life history characteristics of our three species.  We also demonstrated (by a process known as sensitivity analysis) that the most important parameters determining future population fates of all three species were correlation of mean growth rate among colonies; dispersal rate of present and future breeders;  subadult survivorship; and the number of subpopulations (=colonies) - in roughly that descending order of importance. In addition, density dependence was found to markedly alter ITA line shape and position, dramatically in the tern.  Finally, we show that for each of our three seabirds, a substantial reduction in the risk of the entire population's going to extinction was provided by a metapopulation (i.e. colonial) breeding structure -- thus comfortably confirming what avian ecologists have long known but about which population modellers are somtimes still unsure.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Wildlife 2001:  Populations  ","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":" Elsevier","publisherLocation":"London and NY","usgsCitation":"Buckley, P.A., and Downer, R., 1992, Modeling metapopulation dynamics for single species of seabirds, chap. <i>of</i> Wildlife 2001:  Populations  , p. 563-585.","productDescription":"xv, 1163","startPage":"563","endPage":"585","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202213,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a2ce4b07f02db613e51","contributors":{"editors":[{"text":"McCullough, D.R.","contributorId":112162,"corporation":false,"usgs":true,"family":"McCullough","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":507202,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Barrett, R.H.","contributorId":80603,"corporation":false,"usgs":true,"family":"Barrett","given":"R.H.","email":"","affiliations":[],"preferred":false,"id":507201,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Buckley, P.

Models provide a framework for projecting future populations, determining the effects of management decisions on future population dynamics, evaluating extinction probabilities, and addressing a variety of questions of ecological and evolutionary interest. Even when insufficient information exists to allow complete identification of the model, the modelling procedure is useful because it forces the investigator to consider the life history of the species when determining what parameters should be estimated from field studies and provides a context for evaluating the relative importance of demographic parameters. Models have been little used in the study of the population dynamics of passerine birds because of: (1) widespread misunderstandings of the model structures and parameterizations, (2) a lack of knowledge of life histories of many species, (3) difficulties in obtaining statistically reliable estimates of demographic parameters for most passerine species, and (4) confusion about functional relationships among demographic parameters. As a result, studies of passerine demography are often designed inappropriately and fail to provide essential data. We review appropriate models for passerine bird populations and illustrate their possible uses in evaluating the effects of management or other environmental influences on population dynamics. We identify environmental influences on population dynamics. We identify parameters that must be estimated from field data, briefly review existing statistical methods for obtaining valid estimates, and evaluate the present status of knowledge of these parameters.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Wildlife 2001: Populations.

Combinations of attachment and transmitter designs included neoprene cord harness with batteries separate from the transmitter (2 harness designs), Teflon ribbon harness with batteries incorporated into the transmitter package (4 transmitter models), and a package attached directly to the bird with epoxy glue only. Physical effects seen on cranes wearing PTT's ranged from skin lacerations (caused by rubbing of harness material) to no observed effects (other than feather wear). The most successful harness material and design utilized a Teflon ribbon harness with the 4 ribbon ends from the transmitter forming a neck loop and a body loop joined at the sternum. Time spent by sandhill cranes performing most activities did not change after transmitter attachment using this harness method.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Sixth North American Crane Workshop","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Platte River Whooping Crane Maintenance Trust","publisherLocation":"Grand Island, NE","usgsCitation":"Olsen, G.H., Ellis, D.H., Landfried, S., Miller, L., Klugman, S., Fuller, M., and Vermillion, C., 1992, Behavior of sandhill cranes harnessed with different satellite transmitters, chap. <i>of</i> Proceedings of the Sixth North American Crane Workshop, p. 50-56.","productDescription":"vi, 179","startPage":"50","endPage":"56","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200643,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a54e4b07f02db62c3c7","contributors":{"authors":[{"text":"Olsen, Glenn H. 0000-0002-7188-6203 golsen@usgs.gov","orcid":"https://orcid.org/0000-0002-7188-6203","contributorId":40918,"corporation":false,"usgs":true,"family":"Olsen","given":"Glenn","email":"golsen@usgs.gov","middleInitial":"H.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":328932,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ellis, D.

Unfortunately, population changes are generally difficult to identify, and once identified difficult to explain.  Sources of variald (patterns) in population data include: changes in environment that affect carrying capaciyy and produce trend, autocorrelative processes, irregular environmentally induced perturbations, and stochasticity arising from population processes.  In addition. populations are almost never censused and many surveys (e.g., the North American Breeding Bird Survey) produce multiple, incomplete time series of population indices, providing further sampling complications.  We suggest that each source of pattern should be used to address specific hypotheses regarding population change, but that failure to correctly model each source can lead to false conclusions about the dynamics of populations.  We consider hypothesis tests based on each source of pattern, and the effects of autocorrelated observations and sampling error. We identify important constraints on analyses of time series that limit their use in identifying underlying relationships.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Wildlife 2001: Populations","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Elsevier Applied Science","publisherLocation":"New York, New York","collaboration":"  PDF on file: 4190_Barker.pdf","usgsCitation":"Barker, R.J., and Sauer, J., 1992, Modelling population change from time series data, chap. <i>of</i> Wildlife 2001: Populations, p. 182-194.","productDescription":"xv, 1163","startPage":"182","endPage":"194","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200754,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db6884f3","contributors":{"editors":[{"text":"McCullough, D.R.","contributorId":112162,"corporation":false,"usgs":true,"family":"McCullough","given":"D.R.","email":"","affiliations":[],"preferred":false,"id":506680,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Barrett, R.H.","contributorId":80603,"corporation":false,"usgs":true,"family":"Barrett","given":"R.H.","email":"","affiliations":[],"preferred":false,"id":506679,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Barker, R.

A pin feather is taken from a pre-fledging bird for tissue culture and karyotype analysis. Through this method, the sex was identified and the karyotype described of the whooping crane (Grus americana) and the Mississippi sandhill crane (G. canadensis pulla). Giemsa-stained karyotypes of these species showed an identical chromosome constitution with 2n = 78 + 2. However, differences in the amount of centromeric heterochromatin were observed in the Mississippi sandhill crane when compared to the whooping crane C-banded karyotype.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the 1988 North American Crane Workshop","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Florida Game and Fresh Water Fish Commission.","usgsCitation":"Goodpasture, C., Seluja, G., and Gee, G., 1992, Karyotype and identification of sex in two endangered crane species, chap. <i>of</i> Proceedings of the 1988 North American Crane Workshop, p. 219-224.","productDescription":"v, 305","startPage":"219","endPage":"224","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":200685,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b484b","contributors":{"editors":[{"text":"Wood, Don A.","contributorId":112950,"corporation":false,"usgs":true,"family":"Wood","given":"Don","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":506811,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Goodpasture, C.","contributorId":43078,"corporation":false,"usgs":true,"family":"Goodpasture","given":"C.","email":"","affiliations":[],"preferred":false,"id":328845,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Seluja, G.","contributorId":39494,"corporation":false,"usgs":true,"family":"Seluja","given":"G.","email":"","affiliations":[],"preferred":false,"id":328844,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gee, G.","contributorId":64768,"corporation":false,"usgs":true,"family":"Gee","given":"G.","email":"","affiliations":[],"preferred":false,"id":328846,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
