Fast Computing Of Some Generalized Linear Mixed Pseudo-Models With Temporal Autocorrelation, Jay M. Ver Hoef, Josh M. London, Peter L. Boveng Jan 2010

Fast Computing Of Some Generalized Linear Mixed Pseudo-Models With Temporal Autocorrelation, Jay M. Ver Hoef, Josh M. London, Peter L. Boveng

United States Department of Commerce: Staff Publications

This paper considers ways to increase computational speed in generalized linear mixed pseudo-models for the case of many repeated measurements on subjects. We obtain linearly increasing computing time with number of observations, as opposed to O(n3) increasing computing time using numerical optimization. We also find a surprising result; that incomplete optimization for covariance parameters within the larger parameter estimation algorithm actually decreases time to convergence. After comparing various computing algorithms and choosing the best one, we fit a generalized linear mixed model to a binary time series data set with over 100 fixed effects, 50 random effects, …

Invasive tags designed to provide information on animal movements through radio or satellite monitoring have tremendous potential for the study of whales and other cetaceans. However, to date there have been no published studies on the survival of tagged animals over periods of years or decades. Researchers from the National Marine Mammal Laboratory and the Woods Hole Oceanographic Institution tracked five humpback whales with implanted radio tags in southeastern Alaska in August 1976 and July 1977, and tracked two humpback whales in Prince William Sound, Alaska, in June 1978. All seven of these individually identified humpback whales were resighted at …

Movements Of Satellite-Monitored Humpback Whales From New Caledonia, Claire Garrigue, Alexandre N. Zerbini, Ygor Geyer, Mads-Peter Heide-Jørgensen, Wakao Hanaoka, Phil Clapham Jan 2010

Movements Of Satellite-Monitored Humpback Whales From New Caledonia, Claire Garrigue, Alexandre N. Zerbini, Ygor Geyer, Mads-Peter Heide-Jørgensen, Wakao Hanaoka, Phil Clapham

United States Department of Commerce: Staff Publications

Knowledge of the local and migratory movements of humpback whales (Megaptera novaeangliae) from New Caledonia is very limited. To investigate this topic, we attached satellite-monitored tags to 12 whales off southern New Caledonia. Tag longevity ranged from 1 to 52 days (X = 22.5 days). Tagged whales generally moved to the south or southeast, with several spending time in a previously unknown seamount habitat named Antigonia before resuming movement, generally toward Norfolk Island or New Zealand. However, 1 female with a calf traveled the entire length of the western coast of New Caledonia (~450 km) and then …

Seasonal Home Ranges And Fidelity To Breeding Sites Among Ringed Seals, Brendan P. Kelly, Oriana H. Badajos, Mervi Kunnasranta, John R. Moran, Micaela Martinez-Bakker, Peter Boveng, Douglas Wartzok Jan 2010

Seasonal Home Ranges And Fidelity To Breeding Sites Among Ringed Seals, Brendan P. Kelly, Oriana H. Badajos, Mervi Kunnasranta, John R. Moran, Micaela Martinez-Bakker, Peter Boveng, Douglas Wartzok

United States Department of Commerce: Staff Publications

Population structure and patterns of habitat use among ringed seals (Phoca hispida) are poorly known, in part because seasonal movements have not been adequately documented. We monitored the movements of 98 ringed seals in the Beaufort and Chukchi seas between 1990 and 2006 using three forms of telemetry. In the winter—spring period (when the seals were occupying shorefast ice), we used radio and ultra-sonic tags to track movements above and below the ice, respectively. We used satellite-linked transmitters in summer and fall (when the seals ranged away from their winter sites) to track at-sea movements. In the shorefast …

A Mixed-Model Moving-Average Approach To Geostatistical Modeling In Stream Networks, Erin E. Peterson, Jay M. Ver Hoef Jan 2010

A Mixed-Model Moving-Average Approach To Geostatistical Modeling In Stream Networks, Erin E. Peterson, Jay M. Ver Hoef

United States Department of Commerce: Staff Publications

Spatial autocorrelation is an intrinsic characteristic in freshwater stream environments where nested watersheds and flow connectivity may produce patterns that are not captured by Euclidean distance. Yet, many common autocovariance functions used in geostatistical models are statistically invalid when Euclidean distance is replaced with hydrologic distance. We use simple worked examples to illustrate a recently developed moving-average approach used to construct two types of valid autocovariance models that are based on hydrologic distances. These models were designed to represent the spatial configuration, longitudinal connectivity, discharge, and flow direction in a stream network. They also exhibit a different covariance structure than …

Validation Of A Homologous Canine Relaxin Radioimmunoassay And Application With Pregnant And Non-Pregnant Northern Fur Seals (Callorhinus Ursinus), Don R. Bergfelt, Bernard G. Steinetz, J. Lawrence Dunn, Shannon Atkinson, J. Ward Testa, Gregg P. Adams Jan 2010

Validation Of A Homologous Canine Relaxin Radioimmunoassay And Application With Pregnant And Non-Pregnant Northern Fur Seals (Callorhinus Ursinus), Don R. Bergfelt, Bernard G. Steinetz, J. Lawrence Dunn, Shannon Atkinson, J. Ward Testa, Gregg P. Adams

United States Department of Commerce: Staff Publications

The primary objectives of this study were to validate a canine relaxin RIA for use in otariids and phocids and consider practical applications. For 6 captive Northern fur seal females, serum samples were grouped and examined according to pregnancy (n = 13), post-partum (n = 8) and non-pregnancy (n = 6), and, for 2 captive Northern fur seal males, serum samples were grouped and examined together regardless of age (2 mo–15 yrs, n = 6). Placental tissue was available for examination from one Northern fur seal, Steller sea lion and harbor seal. The validation process involved several steps using an …

Foraging Effort Of Juvenile Steller Sea Lions Eumetopias Jubatus With Respect To Heterogeneity Of Sea Surface Temperature, Michelle E. Lander, Thomas R. Loughlin, Miles G. Logsdon, Glenn R. Vanblaricom, Brian Fadely Jan 2010

Foraging Effort Of Juvenile Steller Sea Lions Eumetopias Jubatus With Respect To Heterogeneity Of Sea Surface Temperature, Michelle E. Lander, Thomas R. Loughlin, Miles G. Logsdon, Glenn R. Vanblaricom, Brian Fadely

United States Department of Commerce: Staff Publications

Among many other factors, the decline of the western distinct population segment of Steller sea lions Eumetopias jubatus in Alaska (USA) has been attributed to changes in the distribution or abundance of prey due to the cumulative effects of fisheries and large-scale climate change. However, the depletion of localized prey resources due to small-scale environmental variability and perturbations may be impeding recovery, resulting in the need to understand how the environment currently affects this species on smaller spatial and temporal scales. The objective of this study, there-fore, was to assess how Steller sea lions respond to changes in localized environmental …

System Dynamics Modeling Of Corn Ethanol As A Bio Transportation Fuel In The United States, Deogratias Kibira, Guodong Shao, Stephen Nowak Jan 2010

System Dynamics Modeling Of Corn Ethanol As A Bio Transportation Fuel In The United States, Deogratias Kibira, Guodong Shao, Stephen Nowak

United States Department of Commerce: Staff Publications

The production capacity of corn ethanol as a transportation fuel is experiencing rapid growth in the United States. The demand is driven by increased prices of gasoline, government mandates, incentives, desire for cleaner fuels, and the need to achieve energy independence. Continued strong growth of the corn ethanol industry will depend on profitability by both suppliers and producers. This in turn will be influenced by several factors such as demand, government incentives, feedstock availability and prices, processing plant capacity, and efficient farm and ethanol processing technologies. How and to what extent will the projected growth of the corn ethanol industry …

Predicting The Occurrence Of Atlantic Bluefin Tuna (Thunnus Thynnus) Larvae In The Northern Gulf Of Mexico: Building A Classification Model From Archival Data, Barbara A. Muhling, John T. Lamkin, Mitchell A. Roffer Jan 2010

Predicting The Occurrence Of Atlantic Bluefin Tuna (Thunnus Thynnus) Larvae In The Northern Gulf Of Mexico: Building A Classification Model From Archival Data, Barbara A. Muhling, John T. Lamkin, Mitchell A. Roffer

United States Department of Commerce: Staff Publications

Although bluefin tuna are found throughout the Atlantic Ocean, spawning in the western Atlantic has been recorded predominantly in the Gulf of Mexico (GOM) in spring. Larval bluefin tuna abundances from the northern GOM are formulated into an index used to tune the adult stock assessment, and the variability of this index is currently high. This study investigated whether some of the variability in larval bluefin tuna abundances was related to environmental conditions, by defining associations between larval bluefin tuna catch locations, and a suite of environmental variables. We hypothesized that certain habitat types, as defined by environmental variables, would …

Dreissena And The Disappearance Of The Spring Phytoplankton Bloom In Lake Michigan, Henry A. Vanderploeg, James R. Liebig, Thomas F. Nalepa, Gary L. Fahnenstiel, Steven A. Pothoven Jan 2010

Dreissena And The Disappearance Of The Spring Phytoplankton Bloom In Lake Michigan, Henry A. Vanderploeg, James R. Liebig, Thomas F. Nalepa, Gary L. Fahnenstiel, Steven A. Pothoven

United States Department of Commerce: Staff Publications

We determined the clearance rates of the profunda morph of the quagga mussel (Dreissena bugensis) using seston and Cryptomonas ozolini, a high-quality algal food, for the temperature range 1–7 °C,which is the full temperature range this morph is likely to experience during isothermal conditions or in the hypolimnion of deep lakes. Experiments at 3 °C with the shallow-water morph of the quagga and the zebra mussel provided very similar results. The clearance rates were combined with dreissenid abundance in 0–30 m, 30–50 m, 50–90 m, and >90m depth zones of the southern basin of Lake Michigan to …

Interacting Effects Of Phenotypic Plasticity And Evolution On Population Persistence In A Changing Climate, Thomas E. Reed, Daniel E. Schindler, Robin Waples Jan 2010

Interacting Effects Of Phenotypic Plasticity And Evolution On Population Persistence In A Changing Climate, Thomas E. Reed, Daniel E. Schindler, Robin Waples

United States Department of Commerce: Staff Publications

Climate change affects individual organisms by altering development, physiology, behavior, and fitness, and populations by altering genetic and phenotypic composition, vital rates, and dynamics. We sought to clarify how selection, phenotypic plasticity, and demography are linked in the context of climate change. On the basis of theory and results of recent empirical studies of plants and animals, we believe the ecological and evolutionary issues relevant to population persistence as climate changes are the rate, type, magnitude, and spatial pattern of climate-induced abiotic and biotic change; generation time and life history of the organism; extent and type of phenotypic plasticity; amount …

Development And Application Of A Pollen-Based Paleohydrologic Reconstruction From The Lower Roanoke River Basin, North Carolina, Usa, Debra Willard, Christopher Bernhardt, Roger Brown, Bryan Landacre, Philip A. Townsend Jan 2010

Development And Application Of A Pollen-Based Paleohydrologic Reconstruction From The Lower Roanoke River Basin, North Carolina, Usa, Debra Willard, Christopher Bernhardt, Roger Brown, Bryan Landacre, Philip A. Townsend

United States Geological Survey: Staff Publications

We used pollen assemblages to reconstruct late-Holocene paleohydrologic patterns in floodplain deposits from the lower Roanoke River basin (North Carolina, southeastern USA). Using 120 surface samples from 38 transects, we documented statistical relationships between pollen assemblages, vegetation, and landforms. Backswamp pollen assemblages (long hydroperiods) are dominated by Nyssa (tupelo) and Taxodium (cypress) and have high pollen concentrations. Sediments from elevated levees and seasonally flooded forests (shorter hydroperiods) are characterized by dominant Pinus (pine) pollen, variable abundance of hardwood taxa, and low pollen concentrations. We apply the calibration data set to interpret past vegetation and paleohydrology. Pollen from a radiocarbon-dated sediment …

Vulnerability Of Age-0 Pallid Sturgeon Scaphirhynchus Albus To Fish Predation, W. E. French, Brian D. S. Graeb, S. R. Chipps, Katie N. Bertrand, T. M. Selch, R. A. Klumb Jan 2010

Vulnerability Of Age-0 Pallid Sturgeon Scaphirhynchus Albus To Fish Predation, W. E. French, Brian D. S. Graeb, S. R. Chipps, Katie N. Bertrand, T. M. Selch, R. A. Klumb

United States Geological Survey: Staff Publications

Stocking is a commonly employed conservation strategy for endangered species such as the pallid sturgeon, Scaphirhynchus albus. However, decisions about when, where and at what size pallid sturgeon should be stocked are hindered because vulnerability of pallid sturgeon to fish predation is not known. The objective of this study was to evaluate the vulnerability of age-0 pallid sturgeon to predation by two Missouri River predators under different flow regimes, and in combination with alternative prey. To document vulnerability, age-0 pallid sturgeon (<100 mm) were offered to channel catfish Ictalurus punctatus and smallmouth bass Micropterus dolomieu in laboratory experiments. Selection of pallid sturgeon by both …

Patent Law, Hippo, And The Biodiversity Crisis, 9 J. Marshall Rev. Intell. Prop. L. 624 (2010), Andrew W. Torrance

UIC Review of Intellectual Property Law

Planet earth is host to a dazzling variety of living organisms. This diversity of life, or “biodiversity,” is vital to the survival and prosperity of humanity, supplying such vital amenities as food, clothing, shelter, natural biochemicals useful in medicine, industry, and agriculture, and even irreplaceable ecosystem services, such as clean air and water. Despite the prodigious amount of biodiversity on earth, human activities have been depleting it at an accelerating rate that has now reached the level of a mass extinction event. The five greatest threats to biodiversity can be summarized by the “HIPPO” acronym: (1) Habitat loss, (2) Invasives, …

It was with a considerable degree of hesitation that, during the winter of 1970-71, I sat down and contemplated the scope and structure of a possible book on the waterfowl of North America. On my bookshelf behind me were copies of A. C. Bent's Life Histories of North American Wild Fowl, F. H. Kortright's The Ducks, Geese, and Swans of North America, and Jean Delacour's The Waterfowl of the World. My task, as I saw it, was to try to develop a book that might be useful …

Waterfowl Of North America: Identification Key To North American Waterfowl, Paul A. Johnsgard Jan 2010

Waterfowl Of North America: Identification Key To North American Waterfowl, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

The key on the following pages provides an efficient means of identifying virtually all North American waterfowl that may be examined in the hand. The procedure for using it is comparable to that used for all such dual-choice or "dichotomous" keys. One simply chooses which of the initial descriptive couplets (A or A') best fits the unknown bird. Having chosen one of these, the pair of descriptive couplets (a and a') immediately below the chosen alternative is next considered, without further regard for the rejected one. Subsequent choices, which are sequentially numbered (1 and 1', 2 and 2', etc.) must …

Waterfowl Of North America: Waterfowl Distributions And Migrations In North America, Paul A. Johnsgard Jan 2010

Waterfowl Of North America: Waterfowl Distributions And Migrations In North America, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

The species of waterfowl breeding in North America have distribution patterns that collectively reflect the past geologic and ecological histories of this continent. In general, our waterfowl species may be grouped into those that are limited (endemic) to North America, those that are shared between North and South America, and those that are shared with Europe and/or Asia. Of the forty-four species known to breed in continental North America, the resulting grouping of breeding distributions is as follows:
Limited to North America: Snow goose (also on Greenland and Wrangel Island) , Ross goose, Canada goose (also on Greenland), wood duck, …

Waterfowl Of North America: Pochards (Fresh Water Diving Ducks), Tribe Aythyini, Paul A. Johnsgard Jan 2010

Waterfowl Of North America: Pochards (Fresh Water Diving Ducks), Tribe Aythyini, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010) by Paul A. Johnsgard

Until recent classifications by Jean Delacour and others, the pochard group was not taxonomically distinguished from the more marine-adapted sea ducks, here included in the following tribe Mergini. Nevertheless, the pochards are a readily definable group of mostly medium-sized ducks that differ from their close relatives, the surface-feeding ducks, in several respects. Their legs are situated somewhat farther back on the body, so that they are less adept at walking on land; their feet and associated webs are larger, increasing diving effectiveness (reflected by the increased length of the outer toes); and their bills are generally broad, heavy, and adapted …

Legal Fictions And Juristic Truth, Nancy J. Knauer Jan 2010

Legal Fictions And Juristic Truth, Nancy J. Knauer

St. Thomas Law Review

This Essay reviews the three categories of new fictions outlined above, which I refer to as (1) empirical legal errors; (2) discredited legal regimes; and (3) complex statutory schemes. With respect to each category, I conclude that the appellation of legal fiction is a misnomer and that the integrity of Fuller's classic definition should be retained for its analytic force. The conundrum presented by the legal fiction is that it retains its utility despite its falsity, similar to false statements used in science and mathematics in order to advance a proof or hypothesis. The new legal fictions, however, are different …

Fire Regimes Of The Southern Appalachian Mountains: Temporal And Spatial Variability Over Multiple Scales And Implications For Ecosystem Management, Charles W. Lafon, Henri D. Grissino-Mayer, Sally P. Horn, Robert N. Klein Jan 2010

Fire Regimes Of The Southern Appalachian Mountains: Temporal And Spatial Variability Over Multiple Scales And Implications For Ecosystem Management, Charles W. Lafon, Henri D. Grissino-Mayer, Sally P. Horn, Robert N. Klein

Joint Fire Science Program Research Project Reports

Information about historic fire regimes and the departure of current fire regimes from historic conditions is essential for guiding and justifying management actions, such as prescribed burning programs for ecosystem process restoration and fuel reduction. Such information is noticeably lacking for the southern Appalachian Mountains, where human populations are encroaching onto wildland areas, and where decades of fire exclusion have contributed to the decline of fire-associated communities and also to altered fuel loads. We address this knowledge gap via a multi-scale investigation of the variability in fire regimes over time and space using tree-ring reconstructions of fire history and stand …

Effect Of Season And Interval Of Prescribed Burns In A Ponderosa Pine Ecosystem On Tree Growth And Understory Vegetation., W. G. Thies, Becky K. Kerns, Douglas J. Westlind Jan 2010

Effect Of Season And Interval Of Prescribed Burns In A Ponderosa Pine Ecosystem On Tree Growth And Understory Vegetation., W. G. Thies, Becky K. Kerns, Douglas J. Westlind

Joint Fire Science Program Research Project Reports

After decades of fire exclusion many stands now have historically unprecedented (high) levels of fuels and overstocking. As a result these stands have developed a variety of health issues. In response to these problems land managers are using prescribed fire to restore fuel loads and stand stocking to pre-fire exclusion levels. The impacts of season of prescribed burn as well as burn interval are not well understood. Managers need the ability to better predict these impacts on such things as tree mortality from fire, associated insect attack and disease development, tree growth, and plant communities. The “Season of Burn” study …
