Wintering Sandhill Crane Distribution And Habitat Use Patterns At Bosque Del Apache National Wildlife Refuge, New Mexico, Tandi L. Perkins, Leigh H. Fredrickson

Proceedings of the North American Crane Workshop

The single most important factor regulating sandhill crane (Grus canadensis) populations is their ability to carry out annual life cycle events while responding to changing habitat availability and distribution across local, regional, and continental landscapes. Wetland and cropland resource availability and distribution across the landscape have become increasingly unpredictable. Recent changes in farming practices, urbanization, and prevailing drought conditions in New Mexico have transformed and reduced dynamic, heterogeneous landscapes into scattered fragments of the original setting. Concerns are increasing for the cumulative influence of these often irreversible actions in providing the type of resources needed by cranes at …

Estimating The Extent Of Spatial Association Of Mycobacterium Bovis Infection In Badgers In Ireland, G. E. Kelly, G. E. Mcgrath, S. J. More

Michigan Bovine Tuberculosis Bibliography and Database

Mycobacterium bovis infects the wildlife species badgers Meles meles who are linked with the spread of the associated disease tuberculosis (TB) in cattle. Control of livestock infections depends in part on the spatial and social structure of the wildlife host. Here we describe spatial association of M. bovis infection in a badger population using data from the first year of the Four Area Project in Ireland. Using second-order intensity functions, we show there is strong evidence of clustering of TB cases in each the four areas, i.e. a global tendency for infected cases to occur near other infected cases. Using …

History, Distribution, And Identification Of Exoteleia Dodecella (L.) (Lepidoptera: Gelechiidae) In North America, With Insights Into The Systematics Of Exoteleia Wallengren Using Characters Of The Adult, Immatures, Bionomics, And Dna Barcodes, David Adamski, Jean-Francois Landry, Steven C. Passoa, Robert Tracy

USDA Systematic Entomology Laboratory

Exoteleia dodecella (L.) (Lepidoptera: Gelechiidae), a native of Europe, was first documented from North America at several locations in eastern Canada. Additional records indicate this moth has now spread throughout New England and west to northern Pennsylvania, New York, and possibly into Michigan in the United States. A second introduction of E. dodecella has occurred near the Vancouver area of British Columbia in Canada. To help with the identification of E. dodecella, morphological, biological, and molecular evidence are presented. Key features of the adult, larval, and pupal morphology are compared to other species of Exoteleia and illustrated with line …

The State will use this information to improve our understanding of baseline wetland conditions, and to prioritize wetland restoration and protection activities. Nebraska will continue to work in partnership with landowners, agencies, and organizations to restore and protect 9,000 acres of wetlands. The priorities for the restoration and protection will be determined by the Nebraska Game and Parks Commission and the …

Simple Predictors Of Bite Force In Bats: The Good, The Better, And The Better Still, Patricia W. Freeman, Cliff A. Lemen

University of Nebraska State Museum: Mammalogy Papers

Bite forces of 39 species from six families of New World bats with a variety of diets are quantified with a force meter under field conditions. Using regression approaches we search for a model that is a good morphological predictor of these bite forces. Body mass, an index that ignores differences in skull morphology, has a statistically significant relationship with bite force (R² = 0.76) but is a relatively poor predictor compared with our best model (R² = 0.94). The two best models of the eight we examine are one based on an estimate of strength …

Critical Comment: What We Don’T Recognize Can Hurt Us: A Plea For Awareness About Cryptic Species, Gerardo Pérez-Ponce De León, Steven A. Nadler

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We conducted an extensive literature review on studies that have used DNA sequences to detect cryptic species of parasites during the last decade. Each literature citation that included the term ‘‘cryptic’’ or ‘‘sibling’’ species was analyzed to determine the approach used by the author(s). Reports were carefully filtered to retain only those that recognized the existence of cryptic species centered on the use of DNA sequences. Based on analysis of these papers, we comment on the different ways that parasite cryptic species are discovered in studies focusing on different aspects of the host–parasite relationship, or disciplines, within parasitology. We found …

Morphological Changes And Immunohistochemical Expression Of Rage And Its Ligands In The Sciatic Nerve Of Hyperglycemic Pig (Sus Scrofa), Judyta K. Juranek, Alexey Aleshin, Eileen M. Rattigan, Lynne Johnson, Wu Qu, Fei Song, Radha Ananthakrishnan, Nosirudeen Quadri, Shi Du Yan, Ravichandran Ramasamy, Ann Marie Schmidt, Matthew S. Geddis

Publications and Research

The aim of our project was to study the effect of streptozotocin (STZ)—induced hyperglycemia on sciatic nerve morphology, blood plasma markers and immunohistochemical expression of RAGE (the Receptor for Advanced Glycation End-products), and its ligands—S100B and Carboxymethyl Lysine (CML)-advanced glycation endproduct (AGE) in the laboratory pig. Six months after STZ—injections, blood plasma measurements, morphometric analysis of sciatic nerve fiber density, immunofluorescent distribution of potential molecular neuropathy contributors, ELISA measurement of plasma AGE level and HPLC analysis of sciatic nerve levels of one of the pre-AGE and the glycolysis intermediate products—methyl-glyoxal (MG) were performed. The results of our study revealed that …

Linkage Disequilibrium Estimates Of Contemporary Ne Using Highly Variable Genetic Markers: A Largely Untapped Resource For Applied Conservation And Evolution, Robin Waples, Chi Do

United States Department of Commerce: Staff Publications

Genetic methods are routinely used to estimate contemporary effective population size (N_e) in natural populations, but the vast majority of applications have used only the temporal (two-sample) method. We use simulated data to evaluate how highly polymorphic molecular markers affect precision and bias in the single-sample method based on linkage disequilibrium (LD). Results of this study are as follows: (1) Low-frequency alleles upwardly bias ^N_e, but a simple rule can reduce bias to N_e < 200), and small populations are not likely to be mistaken for large ones. However, it is very difficult to obtain reliable estimates for large populations. (3) With ‘microsatellite’ data, the LD method has greater precision than the temporal method, unless the latter is based on samples taken many generations apart. Our results indicate the LD method has widespread applicability to conservation (which typically focuses on small populations) and the study of evolutionary processes in local populations. Considerable opportunity exists to extract more information about N_e in nature by wider use of single-sample estimators and by combining estimates from different methods.

When Are Genetic Methods Useful For Estimating Contemporary Abundance And Detecting Population Trends?, David A. Tallmon, Dave Gregovich, Robin Waples, C. Scott Baker, Jennifer Jackson, Barbara L. Taylor, Eric Archer, Karen K. Martien, Fred W. Allendorf, Michael K. Schwartz

United States Department of Commerce: Staff Publications

The utility of microsatellite markers for inferring population size and trend has not been rigorously examined, even though these markers are commonly used to monitor the demography of natural populations. We assessed the ability of a linkage disequilibrium estimator of effective population size (N_e) and a simple capture-recapture estimator of abundance (N) to quantify the size and trend of stable or declining populations (true N = 100–10,000), using simulated Wright–Fisher populations. Neither method accurately or precisely estimated abundance at sample sizes of S = 30 individuals, regardless of true N. However, if larger samples …

Phenotypic Plasticity And Population Viability: The Importance Of Environmental Predictability, Thomas E. Reed, Robin Waples, Daniel E. Schindler, Jeffrey J. Hard, Michael T. Kinnison

United States Department of Commerce: Staff Publications

Phenotypic plasticity plays a key role in modulating how environmental variation influences population dynamics, but we have only rudimentary understanding of how plasticity interacts with the magnitude and predictability of environmental variation to affect population dynamics and persistence. We developed a stochastic individual-based model, in which phenotypes could respond to a temporally fluctuating environmental cue and fitness depended on the match between the phenotype and a randomly fluctuating trait optimum, to assess the absolute fitness and population dynamic consequences of plasticity under different levels of environmental stochasticity and cue reliability. When cue and optimum were tightly correlated, plasticity buffered absolute …

Compromising Genetic Diversity In The Wild: Unmonitored Large-Scale Release Of Plants And Animals, Linda Laikre, Michael K. Schwartz, Robin Waples, Nils Ryman, Gem Working Group

United States Department of Commerce: Staff Publications

Large-scale exploitation of wild animals and plants through fishing, hunting and logging often depends on augmentation through releases of translocated or captively raised individuals. Such releases are performed worldwide in vast numbers. Augmentation can be demographically and economically beneficial but can also cause four types of adverse genetic change to wild populations: (1) loss of genetic variation, (2) loss of adaptations, (3) change of population composition, and (4) change of population structure. While adverse genetic impacts are recognized and documented in fisheries, little effort is devoted to actually monitoring them. In forestry and wildlife management, genetic risks associated with releases …

Geographic Variation Of Persistent Organic Pollutant Levels In Humpback Whale (Megaptera Novaeangliae) Feeding Areas Of The North Pacific And North Atlantic, Cristiane T. Elfes, Glenn R. Vanblaricom, Daryle Boyd, John Calambokidis, Phillip J. Clapham, Ronald W. Pearce, Jooke Robbins, Juan Carlos Salinas, Janice M. Straley, Paul R. Wade, Margaret M. Krahn

United States Department of Commerce: Staff Publications

Seasonal feeding behavior and high fidelity to feeding areas allow humpback whales (Megaptera novaeangliae) to be used as biological indicators of regional contamination. Biopsy blubber samples from male individuals (n=67) were collected through SPLASH, a multinational research project, in eight North Pacific feeding grounds. Additional male samples (n=20) were collected from one North Atlantic feeding ground. Persistent organic pollutants were measured in the samples and used to assess contaminant distribution in the study areas. North Atlantic (Gulf of Maine) whales were more contaminated than North Pacific whales, showing the highest levels of polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers …

History And Fate Of A Small Isolated Population Of Weddell Seals At White Island, Antarctica, Thomas S. Gelatt, Corey S. Davis, Ian Stirling, Donald B. Siniff, Curtis Strobeck, Isabelle Delisle

United States Department of Commerce: Staff Publications

Weddell seals (Leptonychotes weddellii Lesson) at White Island, Antarctica form a small, completely enclosed, natural population hypothesized to be of recent origin, likely founded by individuals from nearby Erebus Bay. This population constitutes an ideal model to document a founder event and ensuing genetic drift, with implications for conservation. Here we combined historical accounts, census and tagging data since the late 1960s, and genetic data (41 microsatellite loci and mitochondrial DNA sequences) from 84 individuals representing nearly all individuals present between 1990 and 2000 to investigate the history of the founding of the White Island population, document its population …

Adverse Outcome Pathways And Ecological Risk Assessment: Bridging To Population-Level Effects, Vincent J. Kramer, Matthew A. Etterson, Markus Hecker, Cheryl A. Murphy, Guritno Roesijadi, Daniel J. Spade, Julann A. Spromberg, Magnus Wang, Gerald T. Ankley

United States Department of Commerce: Staff Publications

Maintaining the viability of populations of plants and animals is a key focus for environmental regulation. Population-level responses integrate the cumulative effects of chemical stressors on individuals as those individuals interact with and are affected by their conspecifics, competitors, predators, prey, habitat, and other biotic and abiotic factors. Models of population-level effects of contaminants can integrate information from lower levels of biological organization and feed that information into higher-level community and ecosystem models. As individual-level endpoints are used to predict population responses, this requires that biological responses at lower levels of organization be translated into a form that is usable …

Hierarchical Bayesian Spatial Models For Multispecies Conservation Planning And Monitoring, Carlos Carroll, Devin S. Johnson, Jeffrey R. Dunk, William J. Zielinski

United States Department of Commerce: Staff Publications

Biologists who develop and apply habitat models are often familiar with the statistical challenges posed by their data’s spatial structure but are unsure of whether the use of complex spatial models will increase the utility of model results in planning. We compared the relative performance of nonspatial and hierarchical Bayesian spatial models for three vertebrate and invertebrate taxa of conservation concern (Church’s sideband snails [Monadenia churchi], red tree voles [Arborimus longicaudus], and Pacific fishers [Martes pennanti pacifica]) that provide examples of a range of distributional extents and dispersal abilities. We used presence–absence data derived from regional monitoring programs to develop …

Hydrological Connectivity For Riverine Fish: Measurement Challenges And Research Opportunities, A. H. Fullerton, K. M. Burnett, E. A. Steel, R. L. Flitcroft, G. R. Pess, B. E. Feist, C. E. Torgersen, D. J. Miller, B. L. Sanderson

United States Department of Commerce: Staff Publications

1. In this review,we first summarize how hydrologic connectivity has been studied for riverine fish capable of moving long distances, and then identify research opportunities that have clear conservation significance. Migratory species, such as anadromous salmonids, are good model organisms for understanding ecological connectivity in rivers because the spatial scale over which movements occur among freshwater habitats is large enough to be easily observed with available techniques; they are often economically or culturally valuable with habitats that can be easily fragmented by human activities; and they integrate landscape conditions from multiple surrounding catchment(s) with in-river conditions. Studies have focussed on …

Meridional Patterns In The Deep Scattering Layers And Top Predator Distribution In The Central Equatorial Pacific, Elliott L. Hazen, David W. Johnston

United States Department of Commerce: Staff Publications

The deep scattering layers (DSL) in the central equatorial Pacific form an important prey resource in a relatively oligotrophic habitat. In March of 2006, we used a calibrated 38-kHz SIMRAD EK60 scientific sonar to assess the spatial distribution of the deep scattering layer relative to broad-scale oceanographic features and fine-scale physical and biological measurements. We conducted a single continuous transect from approximately 10°S to 20°N at 170°W while measuring acoustic backscatter, current velocity and direction, temperature, salinity, oxygen, and fluorescence with depth, coincident with marine mammal occurrence. These data were combined with remotely sensed sea surface height, chlorophyll, and sea …

The Malarial Cdk Pfmrk And Its Effector Pfmat1 Phosphorylate Dna Replication Proteins And Co-Localize In The Nucleus, Dayadevi Jirage, Yueqin Chen, Diana Caridha, Michael T. O’Neil, Fredrick Eyase, William H. Witola, Choukri Ben Mamoun, Norman C. Waters

United States Army: Publications

Cyclin-dependent kinases (CDKs) have an established role in metazoans and yeast in DNA replication, transcription and cell cycle regulation. Several CDKs and their effectors have been identified in the malaria parasite Plasmodium falciparum and their biological functions are beginning to be investigated. Here we report results from the functional characterization of Pfmrk and its effector PfMAT1. We validated the interactions between Pfmrk and PfMAT1 and pinpointed their intracellular location. Co-immunoprecipitation studies demonstrated physical interaction between the two proteins and identified the C-terminal domain of PfMAT1 as the Pfmrk activator domain. Immunofluorescence analyses using GFP and RFP-tagged versions of Pfmrk and …

Evaluation Of Multiple (3-Cycle) Decontamination Processing For Filtering Facepiece Respirators, Michael S. Bergman, Dennis J. Viscusi, Brian K. Heimbuch, Joseph D. Wander, Anthony R. Sambol, Ronald E. Shaffer

United States Air Force: Publications

Disposable N95 filtering facepiece respirators (FFRs) certified by the National Institute for Occupational Safety and Health (NIOSH) are widely used by healthcare workers to reduce exposures to infectious biological aerosols. There is currently major concern among public health officials about a possible shortage of N95 FFRs during an influenza pandemic. Decontamination and reuse of FFRs is a possible strategy for extending FFR supplies in an emergency; however, the NIOSH respirator certification process does not currently include provisions for decontamination and reuse. Recent studies have investigated the laboratory performance (filter aerosol penetration and filter airflow resistance) and physical integrity of FFRs …
