We describe a hierarchical modeling approach to the analysis of these data, in which parameters associated with the individual species estimates are treated as random variables, and probability statements are made about the species parameters conditioned on the data.  A Markov-Chain Monte Carlo (MCMC) procedure is used to fit the hierarchical model.  This approach is computer intensive, and is based upon simulation. MCMC allows for estimation both of parameters and of derived statistics.  To illustrate the application of this method, we use the case in which we are interested in attributes of a collection of estimates of population change.  Using data for 28 species of grassland-breeding birds from the North American Breeding Bird Survey, we estimate the number of species with increasing populations, provide precision-adjusted rankings of species trends, and describe a measure of population stability as the probability that the trend for a species is within a certain interval.  Hierarchical models can be applied to a variety of bird survey applications, and we are investigating their use in estimation of population change from survey data.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ornis Hungarica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Proceeding of the Bird Numbers Conference, Nyiregyhaza, Hungary, 2001.  6492_Sauer.pdf","usgsCitation":"Sauer, J., and Link, W., 2003, Hierarchical models and the analysis of bird survey information: Ornis Hungarica, v. 12-13, no. 1-2, p. 217-222.","productDescription":"217-222","startPage":"217","endPage":"222","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202045,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17351,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://kornel.zool.klte.hu/pub/ornis/articles/OrnisHungarica_vol12-13_p217-223.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"12-13","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b12e4b07f02db6a2812","contributors":{"authors":[{"text":"Sauer, J.R. 0000-0002-4557-3019","orcid":"https://orcid.org/0000-0002-4557-3019","contributorId":66197,"corporation":false,"usgs":true,"family":"Sauer","given":"J.R.","affiliations":[],"preferred":false,"id":342071,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Link, W.A. 0000-0002-9913-0256","orcid":"https://orcid.org/0000-0002-9913-0256","contributorId":8815,"corporation":false,"usgs":true,"family":"Link","given":"W.A.","affiliations":[],"preferred":false,"id":342070,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study provides a rationale for monitoring nekton in shallow (< 1 m), temperate, estuarine habitats and addresses some important issues that arise when developing monitoring protocols. Sampling in seagrass and salt marsh habitats is emphasized due to the susceptibility of each habitat to anthropogenic stress and to the abundant and rich nekton assemblages that each habitat supports. Extensive sampling with quantitative enclosure traps that estimate nekton density is suggested. These gears have a high capture efficiency in most habitats and are small enough (e.g., 1 m(2)) to permit sampling in specific microhabitats. Other aspects of nekton monitoring are discussed, including spatial and temporal sampling considerations, station selection, sample size estimation, and data collection and analysis. Developing and initiating long-term nekton monitoring programs will help evaluate natural and human-induced changes in estuarine nekton over time and advance our understanding of the interactions between nekton and the dynamic estuarine environment.","language":"English","publisher":"Springer","doi":"10.1023/A:1021389327224","usgsCitation":"Raposa, K., Roman, C.T., and Heltshe, J., 2003, Monitoring nekton as a bioindicator in shallow estuarine habitats: Environmental Monitoring and Assessment, v. 81, no. 1-3, p. 239-255, https://doi.org/10.1023/A:1021389327224.","productDescription":"17 p.","startPage":"239","endPage":"255","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":489094,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://digitalcommons.uri.edu/nrs_facpubs/732","text":"External Repository"},{"id":387517,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b04e4b07f02db69904d","contributors":{"authors":[{"text":"Raposa, K.B.","contributorId":104596,"corporation":false,"usgs":true,"family":"Raposa","given":"K.B.","affiliations":[],"preferred":false,"id":341447,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Roman, C.

Waterfowl surveys provide population estimates for breeding ducks over most of the continent, the North American Breeding Bird Survey (BBS) provides indexes to population change for >400 breeding bird species, and many other surveys exist that index bird populations at a variety of scales and seasons. However, many fundamental questions about bird population change remain unanswered. I suggest that analyses of monitoring data provide limited understanding of causes of population change, and that the declining species paradigm (Caughley 1994) is sometimes an inefficient approach to increasing our understanding of causes of population change. In North America, the North American Bird Conservation Initiative (NABCI) provides an opportunity to implement alternative approaches that use management, modeling of population responses to management, and monitoring in combination to increase our understanding of bird populations. In adaptive resources management, modeling provides predictions about consequences of management, and monitoring data allow us to assess the population consequences of management. In this framework, alternative hypotheses about response of populations to management can be evaluated by formulating a series of models with differing structure, and management and monitoring provide information about which model best predicts population response.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ornis Hungarica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Proceeding of the Bird Numbers Conference, Nyiregyhaza, Hungary, 2001.  7068_Sauer.pdf","usgsCitation":"Sauer, J., 2003, Developing a general conceptual framework for avian conservation science: Ornis Hungarica, v. 12-13, p. 25-33.","productDescription":"25-33","startPage":"25","endPage":"33","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202143,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17353,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://kornel.zool.klte.hu/pub/ornis/articles/OrnisHungarica_vol12-13_p25-33.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"12-13","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa8e4b07f02db667321","contributors":{"authors":[{"text":"Sauer, J.R. 0000-0002-4557-3019","orcid":"https://orcid.org/0000-0002-4557-3019","contributorId":66197,"corporation":false,"usgs":true,"family":"Sauer","given":"J.R.","affiliations":[],"preferred":false,"id":343228,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

At smaller geographic scales, many states and provinces conduct surveys of colonial waterbird populations. Periodic regional surveys are conducted at varying times during the breeding season using a variety of survey methods, which complicates attempts to estimate population trends for most species. The US Geological Survey Patuxent Wildlife Research Center has recently started to coordinate colonial waterbird monitoring efforts throughout North America. A centralized database has been developed with an Internet-based data entry and retrieval page. The extent of existing colonial waterbird surveys has been defined, allowing gaps in coverage to be identified and basic inventories completed where desirable. To enable analyses of comparable data at regional or larger geographic scales, sampling populations through statistically sound sampling designs should supersede obtaining counts at every colony. Standardized breeding season survey techniques have been agreed upon and documented in a monitoring manual. Each survey in the manual has associated with it recommendations for bias estimation, and includes specific instructions on measuring detectability. The methods proposed in the manual are for developing reliable, comparable indices of population size to establish trend information at multiple spatial and temporal scales, but they will not result in robust estimates of total population numbers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ornis Hungarica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Proceeding of the Bird Numbers Conference, Nyiregyhaza, Hungary, 2001.  7069_Steinkamp.pdf","usgsCitation":"Steinkamp, M., Peterjohn, B., and Keisman, J., 2003, Incorporating precision, accuracy and alternative sampling designs into a continental monitoring program for colonial waterbirds: Ornis Hungarica, v. 12-13, p. 209-217.","productDescription":"209-217","startPage":"209","endPage":"217","numberOfPages":"9","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202184,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17354,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://kornel.zool.klte.hu/pub/ornis/articles/OrnisHungarica_vol12-13_p209-217.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"12-13","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fae4b07f02db5f4287","contributors":{"authors":[{"text":"Steinkamp, Melanie J. 0000-0001-9322-609X","orcid":"https://orcid.org/0000-0001-9322-609X","contributorId":101773,"corporation":false,"usgs":false,"family":"Steinkamp","given":"Melanie J.","affiliations":[],"preferred":false,"id":343231,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Peterjohn, B.G.","contributorId":25255,"corporation":false,"usgs":true,"family":"Peterjohn","given":"B.G.","email":"","affiliations":[],"preferred":false,"id":343230,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Keisman, J.L.","contributorId":12161,"corporation":false,"usgs":true,"family":"Keisman","given":"J.L.","affiliations":[],"preferred":false,"id":343229,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Quail have been studied extensively in the laboratory as models for understanding avian endocrinology and behavior, and as a subject for toxicological research and testing. In the lab, Japanese quail show age-related deterioration in endocrine, behavioral, and sensory system responses; the American kestrel is relatively long lived and shows moderate evidence of senescence in the oldest birds. Using data collected from captive kestrels at the Patuxent Wildlife Research Center, a database was designed to document selected parameters over the life cycle of the kestrels. Life table data collated from many species indicate that longer lived species of birds show senescence in survival ability but this pattern has not been established for reproductive function. We suggest that useful comparisons among species can be made by identifying stages in reproductive life history, organized on a relative time scale. Preliminary data from quail and kestrels, admittedly only two species, do not yet indicate a pattern of greater reproductive senescence in longer-lived birds.

While it is usually difficult to determine the age class of a randomly encountered individual, it is often the case that the individual can be readily and reliably assigned to one of a set of age classes. For example, it is often possible to distinguish first-year from older birds. In such cases, the population age structure can be regarded as a latent variable governed by a process prior, and the data as summaries of this latent structure. In this article, we consider the problem of uncovering the latent structure and estimating process parameters from summaries of age class information. We present a demographic analysis for the critically endangered migratory population of whooping cranes (Grus americana), based only on counts of first-year birds and of older birds. We estimate age and year-specific survival rates. We address the controversial issue of whether management action on the breeding grounds has influenced recruitment, relating recruitment rates to the number of seventh-year and older birds, and examining the pattern of variation through time in this rate.","language":"English","publisher":"International Biometric Society","doi":"10.1111/j.0006-341X.2003.00091.x","usgsCitation":"Link, W., Royle, J., and Hatfield, J.S., 2003, Demographic analysis from summaries of an age-structured population: Biometrics, v. 59, no. 4, p. 778-785, https://doi.org/10.1111/j.0006-341X.2003.00091.x.","productDescription":"8 p.","startPage":"778","endPage":"785","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201785,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"59","issue":"4","noUsgsAuthors":false,"publicationDate":"2003-12-11","publicationStatus":"PW","scienceBaseUri":"4f4e4ab2e4b07f02db66ed74","contributors":{"authors":[{"text":"Link, William A. wlink@usgs.gov","contributorId":3465,"corporation":false,"usgs":true,"family":"Link","given":"William A.","email":"wlink@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":341408,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Royle, J.

We found Swamp Sparrows throughout their formerly documented range except in southern Chesapeake Bay.  Swamp Sparrows were most common in the Mullica River region of New Jersey where we detected individuals at 78% of systematically chosen points with a mean count of 4.1 birds/point.  The percentages of points with positive detections in. the regions of Delaware River (39%), eastern Delaware Bay (23%), western Delaware Bay (34%), and Tuckahoe River (31%) were lower.  The mean count of birds/point was between 0.4 and 0.6 in these regions.  A higher resolution Poisson model of relative abundance suggested that the greatest concentrations of Swamp Sparrows occurred not only in the Mullica River area but also along northwestern Delaware Bay.  Regression analysis of Swamp Sparrow counts and habitat features identified shrubs (Iva frutescens and Baccharis halimifolia) as a key habitat component.  By applying density estimates generated by DISTANCE (Thomas et al. 1998) to the approximate area of potential shrub habitat along Delaware Bay, we estimated that the core population of Coastal Plain Swamp Sparrows was less than 28,000 pairs.

We used up to 34 years of capture-recapture data from about 22 100 new releases of day-old&nbsp;</span>female<span>&nbsp;ducklings and&nbsp;</span>multistate<span>&nbsp;modelling to test predictions about the influence of environmental, habitat and management factors on&nbsp;</span>natal<span>&nbsp;</span>dispersal<span>&nbsp;probability of three species of&nbsp;</span>ducks<span>&nbsp;within the Engure Marsh, Latvia. 2. The mean&nbsp;</span>natal<span>&nbsp;</span>dispersal<span>&nbsp;distances were very similar (c. 0.6-0.7 km) for all three species and were on average 2.7 times greater than breeding&nbsp;</span>dispersal<span>&nbsp;distances recorded within the same study system. 3. We were unable to confirm the kinship hypothesis and found no evidence that young first-nesting females nested closer to their relatives (either mother or sister) than to the&nbsp;</span>natal<span>&nbsp;nest. 4. Young&nbsp;</span>female<span>&nbsp;northern shovelers, like adults, moved from small islands to the large island when water level was high and vice versa when water level was low before the construction of elevated small islands.&nbsp;</span>Movement<span>&nbsp;probabilities between the two strata were much higher for young shovelers than adults, suggesting that young birds had not yet developed strong fidelity to the&nbsp;</span>natal<span>&nbsp;site. Movements of young&nbsp;</span>female<span>&nbsp;tufted&nbsp;</span>ducks<span>, unlike those of shovelers, were not dependent on water level fluctuations and reflected substantial flexibility in choice of first nesting sites. 5. Data for young birds supported our earlier conclusion that common pochard nesting habitats in black-headed gull colonies were saturated during the entire study period. Young females, like the two adult age groups, moved into and out of colonies with similar probability. Fidelity probability of&nbsp;</span>female<span>&nbsp;pochards to each stratum increased with age, being the lowest (0.62) for young (DK) females, intermediate (0.78) for yearlings (SY) and the highest (0.84) for adult (ASY) females. 6. Young&nbsp;</span>female<span>&nbsp;tufted&nbsp;</span>ducks<span>, like adults, showed higher probabilities of moving from islands to emergent marshes when water levels were higher both before and after habitat management. The relationship between the spring water levels and&nbsp;</span>movement<span>&nbsp;was much weaker for young females than for adults. 7. Young&nbsp;</span>female<span>&nbsp;diving&nbsp;</span>ducks<span>&nbsp;exhibited much stronger (compared to adults) asymmetric&nbsp;</span>movement<span>&nbsp;with respect to proximity to water, with higher&nbsp;</span>movement<span>&nbsp;probabilities to near-water locations than away from these locations. 8.

Several factors have been put forward to explain risks of extinction, including ecological and life history characteristics of individuals.  For instance, factors that affect the balance between natality and mortality can have profound effects on population persistence.  Sexual selection has been identified as one such factor.  Populations under strong sexual selection experience a number of costs ranging from increased predation and parasitism to enhanced sensitivity to environmental and demographic stochasticity.  These findings have led to the prediction that local extinction rates should be higher for species/populations with intense sexual selection.  We tested this prediction by analyzing the dynamics of natural bird communities at a continental scale over a period of 21 years (1975-1996), using relevant statistical tools.  In agreement with the theoretical prediction, we found that sexual selection increased risks of local extinction (dichromatic birds had on average a 23% higher local extinction rate than monochromatic species).  However, despite higher local extinction probabilities, the number of dichromatic species did not decrease over the period considered in this study.  This pattern was caused by higher local turnover rates of dichromatic species, resulting in relatively stable communities for both groups of species.  Our results suggest that these communities function as metacommunities, with frequent local extinctions followed by colonization.  Anthropogenic factors impeding dispersal might therefore have a significant impact on the global persistence of sexually selected species.","language":"English","publisher":"National Academy of Sciences","doi":"10.1073/pnas.0836953100","usgsCitation":"Doherty, P.F., Sorci, G., Royle, J., Hines, J., Nichols, J., and Boulinier, T., 2003, Sexual selection affects local extinction and turnover in bird communities: Proceedings of the National Academy of Sciences, v. 100, no. 10, p. 5858-5862, https://doi.org/10.1073/pnas.0836953100.","productDescription":"5 p.","startPage":"5858","endPage":"5862","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":478313,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://doi.org/10.1073/pnas.0836953100","text":"External Repository"},{"id":199443,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"100","issue":"10","noUsgsAuthors":false,"publicationDate":"2003-04-07","publicationStatus":"PW","scienceBaseUri":"4f4e4b06e4b07f02db69a46b","contributors":{"authors":[{"text":"Doherty, Paul F.

We draw together > 50 years of research on the Huntington Wildlife Forest in the central Adirondack Mountains of New York to explore regeneration of northern hardwoods.  A series of studies each of which focused on a single factor failed to identify the cause of regeneration failure.  However, integration of these studies led to broader understanding of the process of forest stand development and identified at least three interacting factors: lighting regime, competing vegetation and selective browsing by white-tailed deer (Odocoileus virginianus).  The diverse 100-200 year-old hardwood stands present today probably reflect regeneration during periods of low deer density (< 2.0 deer/km super(2)) and significant forest disturbance.  If this hypothesis is correct, forest managers can mimic these 'natural windows of opportunity' through manipulation of a few sensitive variables in the system.  Further, these manipulations can be conducted on a relatively small geographic scale.  Control of deer densities on a scale of 500 ha and understory American beech (Fagus grandifolia) on a scale of < 100 ha in conjunction with an even-aged regeneration system consistently resulted in successful establishment of desirable hardwood regeneration.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal for Nature Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1078/1617-1381-00021","usgsCitation":"Sage, R., Porter, W., and Underwood, H., 2003, Windows of opportunity: white-tailed deer and the dynamics of northern hardwood forests of the northeastern US: Journal for Nature Conservation, v. 10, no. 4, p. 213-220, https://doi.org/10.1078/1617-1381-00021.","productDescription":"213-220","startPage":"213","endPage":"220","numberOfPages":"8","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198241,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":17285,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1078/1617-1381-00021","linkFileType":{"id":5,"text":"html"}}],"volume":"10","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e4b5a","contributors":{"authors":[{"text":"Sage, R.W.","contributorId":92387,"corporation":false,"usgs":true,"family":"Sage","given":"R.W.","affiliations":[],"preferred":false,"id":341252,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Porter, W.F.","contributorId":81597,"corporation":false,"usgs":true,"family":"Porter","given":"W.F.","email":"","affiliations":[],"preferred":false,"id":341250,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"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":341251,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
