Florida Seagrass Habitat Evaluation: A Comparative Survey For Chemical Quality, Michael A. Lewis, Darrin D. Dantin, Cynthia A. Chancy, Kathryn Abel, Christopher G. Lewis

United States Environmental Protection Agency: Publications

Contaminant concentrations were determined for media associated with 13 Florida seagrass beds. Concentrations of 10 trace metals were more commonly detected in surface water, sediment and two seagrass species than PAHs, pesticides and PCBs. Concentrations of copper and arsenic in surface water exceeded Florida aquatic life criteria more frequently than other trace elements. Total organic carbon, mercury, chromium, zinc, total chlordane, total PAHs, total PCBs, DDD and DDE were significantly greater in seagrass-rooted sediments than adjacent non-vegetated sediments. Total DDT, DDD, DDE, total chlordane, arsenic, copper and nickel exceeded proposed sediment quality guidelines at six of 13 grass beds. Pesticides, …

American Woodcock Population Status, 2007, James R. Kelley Jr., Rebecca D. Rau

United States Fish and Wildlife Service: Publications

Singing-ground Survey data indicated that the numbers of displaying American woodcock (Scolopax minor) in the Eastern Region in 2007 declined 11.6% from 2006; however, the Central Region was unchanged. There was no significant trend in woodcock heard in either the Eastern or Central Region during 1997-07. This represents the fourth consecutive year that the 10-year trend estimate did not indicate a significant decline. There were long-term (1968-07) declines of 2.0% per year in the Eastern Region and 1.8% per year in the Central Region. The 2006 recruitment index for the U.S. portion of the Eastern Region (1.5 immatures …

Valentine National Wildlife Refuge 2007

United States Fish and Wildlife Service: Publications

INTRODUCTION

Valentine National Wildlife Refuge (NWR) was established on August 4, 1935 under the Migratory Bird Conservation Act by Executive Order 7142. The purpose of the refuge as stated in the executive order is “as a refuge and breeding ground for migratory birds and other wildlife.” Acquisition funding came from Duck Stamp sales and the Emergency Conservation Fund Of 1933.

The 71,772-acre Valentine NWR is located in the Sandhills of north-central Nebraska. The Sandhills contain the largest remaining stands of mid and tall grass native prairie left in North America. The refuge is a unique and ecologically important component of …

Sandhill Crane Abundance And Nesting Ecology At Grays Lake, Idaho, Jane Austin, Adonia Henry, I. Joseph Hall

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We examined population size and factors influencing nest survival of greater sandhill cranes (Grus canadensis tabida) at Grays Lake National Wildlife Refuge, Idaho, USA, during 1997–2000. Average local population of cranes from late April to early May, 1998–2000, was 735 cranes, 34% higher than that reported for May 1970–1971. We estimated 228 (SE = 30) nests in the basin core (excluding renests), 14% higher than a 1971 estimate. Apparent nest success in our study (x = 60%, n = 519 nests) was lower than reported for Grays Lake 30–50 years earlier. Daily survival rates (DSRs) of all nests …

Femur-Marrow Fat Of White-Tailed Deer Fawns Killed By Wolves, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

I present marrow fat (MF) data from a large sample of white-tailed deer fawns killed by wolves and a sample of fawns that died by accident in a single area, and I use these data to explore the extent that poor nutritional condition may have predisposed fawns to wolf predation. Percent MF of 110 5–10-month-old white-tailed deer (Odocoileus virginianus) fawns killed by wolves (Canis lupus) from November through April 1984–2002 in northeastern Minnesota, USA, was lower than MF for 23 fawns killed by accidents in the same area and period. The MF of both male and …

A Proposed Ethogram Of Large-Carnivore Predatory Behavior, Exemplified By The Wolf, Daniel Macnulty, L. David Mech, Douglas Smith

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Although predatory behavior is traditionally described by a basic ethogram composed of 3 phases (search, pursue, and capture), behavioral studies of large terrestrial carnivores generally use the concept of a ‘‘hunt’’ to classify and measure foraging. This approach is problematic because there is no consensus on what behaviors constitute a hunt. We therefore examined how the basic ethogram could be used as a common framework for classifying large carnivore behavior. We used >2,150 h of observed wolf (Canis lupus) behavior in Yellowstone National Park, including 517 and 134 encounters with elk (Cervus elaphus) and American bison …

Interleukin-6 And Tumor Necrosis Factor-Alpha Values In Elk Neonates, Shannon M. Barber-Meyer, Craig R. Johnson, Michael P. Murtaugh, L. David Mech, P. J. White

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Serological indicators of general condition would be helpful for monitoring or assessing ungulate wildlife. Toward that end, we report the 1st reference values for 2 cytokines, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), in neonatal elk (Cervus elaphus). We obtained blood samples from 140 calves ≤ 6 days old in Yellowstone National Park during summer 2003–2005. IL-6 values ranged from 0 to 1.21 pg/ml with a median of 0.03 pg/ml. TNF-α values ranged from 0 to 225.43 pg/ml with a median of 1.85 pg/ml. IL-6 and TNF-α concentrations were not significant predictors of elk calf survival through 21 …

Anasazi (Pre-Columbian Native-American) Migrations During The Middle-12th And Late-13th Centuries – Were They Drought Induced?, Larry Benson, Kenneth Petersen, John Stein

United States Geological Survey: Staff Publications

Severe droughts in the middle-12th and late-13th centuries appear to have affected Anasazi (pre-Columbian Native American) populations. During the first drought most of the great houses in the central San Juan Basin were vacated; the second drought resulted in the abandonment of the Four Corners region. During the first drought, villages may not have been completely abandoned. The multi-year drought periods probably were characterized by reductions in both winter and summer precipitation. Maize is dependent on winter precipitation for its germination and initial growth and on summer (monsoonal) precipitation for its continued growth. Reductions in precipitation are hypothesized to have …

Hydrologic Connectivity And The Contribution Of Stream Headwaters To Ecological Integrity At Regional Scales1, Mary C. Freeman, Catherine M. Pringle, C. Rhett Jackson

United States Geological Survey: Staff Publications

Cumulatively, headwater streams contribute to maintaining hydrologic connectivity and ecosystem integrity at regional scales. Hydrologic connectivity is the water-mediated transport of matter, energy and organisms within or between elements of the hydrologic cycle. Headwater streams compose over two-thirds of total stream length in a typical river drainage and directly connect the upland and riparian landscape to the rest of the stream ecosystem. Altering headwater streams, e.g., by channelization, diversion through pipes, impoundment and burial, modifies fluxes between uplands and downstream river segments and eliminates distinctive habitats. The large-scale ecological effects of altering headwaters are amplified by land uses that alter …

Butterfly Responses To Prairie Restoration Through Fire And Grazing, Jennifer A. Vogel, Diane M. Debinski, Rolf R. Koford, James R. Miller

United States Geological Survey: Staff Publications

The development of land for modern agriculture has resulted in losses of native prairie habitat. The small, isolated patches of prairie habitat that remain are threatened by fire suppression, overgrazing, and invasion by non-native species. We evaluated the effects of three restoration practices (grazing only, burning only, and burning and grazing) on the vegetation characteristics and butterfly communities of remnant prairies. Total butterfly abundance was highest on prairies that were managed with burning and grazing and lowest on those that were only burned. Butterfly species richness did not differ among any of the restoration practices. Butterfly species diversity was highest …

Genetically Attenuated Plasmodium Berghei Liver Stages Induce Sterile Protracted Protection That Is Mediated By Major Histocompatibility Complex Class I–Dependent Interferon-Y–Producing Cd8+ T Cells, Ousman Jobe, Joanne Lumsden, Ann-Kristin Mueller, Jackie Williams, Hilda Silva-Rivera, Stefan H. I. Kappe, Robert J. Schwenk, Kai Matuschewski, Urszula Krzych

United States Army: Publications

At present, radiation-attenuated plasmodia sporozoites (y-spz) is the only vaccine that induces sterile and lasting protection in malaria-naive humans and laboratory rodents. However, g-spz are not without risks. For example, the heterogeneity of the y-spz could explain occasional breakthrough infections. To avoid this possibility, we constructed a double-knockout P. berghei parasite by removing 2 genes, UIS3 and UIS4, that are up-regulated in infective spz.We evaluated the double-knockout Pbuis3(-)/4(-) parasites for protective efficacy and the contribution of CD8+ T cells to protection. Pbuis3(-)/4(-) spz induced sterile and protracted protection in C57BL/6 mice. Protection was linked to CD8+ …

Factors Influencing Movement Probabilities Of Big Brown Bats (Eptesicus Fuscus) In Buildings, Laura E. Ellison, Thomas J. O’Shea, Daniel J. Neubaum, Richard Bowen

United States Geological Survey: Staff Publications

We investigated movements of female big brown bats (Eptesicus fuscus) roosting in maternity colonies in buildings in Fort Collins, Colorado (USA), during the summers of 2002, 2003, and 2005. This behavior can be of public health concern where bats that may carry diseases (e.g., rabies) move among buildings occupied by people. We used passive integrated transponders (PIT tags) to mark individual bats and hoop PIT readers at emergence points to passively monitor the use of building roosts by marked adult females on a daily basis during the lactation phase of reproduction. Multi-strata models were used to examine movements …

Conservation Biology For Suites Of Species: Demographic Modeling For Pacific Island Kingfishers, Dylan C. Kesler, Susan M. Haig

United States Geological Survey: Staff Publications

Conservation practitioners frequently extrapolate data from single-species investigations when managing critically endangered populations. However, few researchers initiate work with the intent of making findings useful to conservation efforts for other species. We presented and explored the concept of conducting conservation-oriented research for suites of geographically separated populations with similar natural histories, resource needs, and extinction threats. An example was provided in the form of an investigation into the population demography of endangered Micronesian kingfishers (Todiramphus cinnamominus). We provided the first demographic parameter estimates for any of the 12 endangered Pacific Todiramphus species, and used results to develop a …

Using Adaptive Management To Meet Conservation Goals, Thomas M. Franklin Franklin, Ronald Helinski Helinski, Andrew Manale Manale

United States Environmental Protection Agency: Publications

Natural resource professionals should know whether or not they are doing an effective job of managing natural resources. Their decision-making process should produce the kind of results desired by the public, elected officials, and their agencies’ leadership. With billions of dollars spent each year on managing natural resources, accountability is more important than ever. Producing results is the key to success. Managers must have the necessary data to make enlightened decisions during program implementation—not just at the conclusion of a program. Adaptive management is described as an adapt-and-learn methodology as it pertains to implementing Farm Bill conservation practices. Four regional …

United States Environmental Protection Agency: Publications

A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals and populations interact with their environment. In this paper we summarize an extensive body of work examining the adaptive responses of Fundulus species to environmental conditions, and describe how this research has contributed importantly to our understanding of physiology, gene regulation, toxicology, and ecological and evolutionary genetics of teleosts and other vertebrates. These explorations have reached a critical juncture at which advancement is hindered by the lack of genomic resources for these …

A Novel Endonuclease Activity Associated With The Arabidopsis Ortholog Of The 30-Kda Subunit Of Cleavage And Polyadenylation Specificity Factor, Balasubrahmanyam Addepalli, Arthur G. Hunt

Plant and Soil Sciences Faculty Publications

The polyadenylation of messenger RNAs is mediated by a multi-subunit complex that is conserved in eukaryotes. Among the most interesting of these proteins is the 30-kDa-subunit of the Cleavage and Polyadenylation Specificity Factor, or CPSF30. In this study, the Arabidopsis CPSF30 ortholog, AtCPSF30, is characterized. This protein possesses an unexpected endonucleolytic activity that is apparent as an ability to nick and degrade linear as well as circular single-stranded RNA. Endonucleolytic action by AtCPSF30 leaves RNA 3′ ends with hydroxyl groups, as they can be labeled by RNA ligase with [³²P]-cytidine-3′,5′-bisphosphate. Mutations in the first of the three CCCH …

Characteristics Of Reduced Fat Milks As Influenced By The Incorporation Of Folic Acid, K. Achanta, C. A. Boeneke, K. J. Aryana

Faculty Publications

Folic acid plays an important role in the prevention of neural tube defects (e.g., spina bifida and anencephaly), heart defects, facial clefts, urinary abnormalities, and limb deficiencies. Milk and milk products serve as a potential source for folic acid fortification because of the presence of folate-binding proteins that seem to be involved in folate bioavailability. Although milk is not a good source of folic acid, fortification could help in the prevention of the above-mentioned defects. The objective of this study was to examine the physicochemical characteristics of reduced fat milks fortified with folic acid. Reduced fat milks were prepared using …

Use Of The Global Positioning System In The Field Recovery Of Scattered Human Remains, Ginesse A. Listi, Mary H. Manhein, Michael Leitner

Faculty Publications

This study examines the Global Positioning System (GPS) as a tool for field mapping of scattered human remains or other materials in forensic investigations. Two aspects of the GPS are considered: (1) the level of accuracy that can be obtained using a mid-priced GPS unit, and (2) the effectiveness of using the GPS to map scattered materials. The positional accuracy of the GPS receiver was tested using a National Geodetic Survey (NGS) point located in Baton Rouge, LA. The utility of the GPS for mapping was investigated by setting up a mock field recovery and mapping the remains using both …

Fragile Democracies, Samuel Issacharoff

Faculty Articles

Democratic regimes around the world find themselves besieged by antidemocratic groups that seek to use the electoral arena as a forum to propagandize their causes and rally their supporters. Virtually all democratic countries respond by restricting the participation of groups or political parties deemed to be beyond the range of tolerable conduct or viewpoints. The proscription of certain views raises serious problems for any liberal theory in which legitimacy turns on the democratic consent of the governed. When stripped down to their essentials, all definitions of democracy rest ultimately on the primacy of electoral choice and the presumptive claim of …

Bell Atlantic V. Twombly: How Motions To Dismiss Become (Disguised) Summary Judgments, Richard A. Epstein

Faculty Articles

The recent Supreme Court decision in Bell Atlantic v. Twombly stands at the crossroads of antitrust and civil procedure. As an antitrust case, Twombly makes sense on structural grounds. The FCC regulation of the telecommunications industry, and the many innocent explanations as to why each telecommunications company would stay out of its rival's territories obviated the need for further discovery. But in many other contexts, including Conley v. Gibson a case involving potential breach of the duty of fair representation on matters of racial discrimination discovery could flesh out the relevant factual issues. The Supreme Court's general disapproval of Conley …

The "Charles Stimson" Rule And Three Other Proposals To Protect Lawyers From Lawyers, Stephen Gillers

Faculty Articles

Lawyers can be “at the edge” for many different reasons. For purposes of this Article, I define “at the edge” to mean lawyers who for one of two reasons encounter risks of, or actual harm to, their career, freedom, physical safety, reputation, or income. The two reasons are the identity of the lawyer’s client, or the nature of the claim the lawyer is making in court, or both. Lawyers may also be at risk for tactics that bring sanctions. But that is a different kind of risk, a risk of crossing an ethical or legal boundary, and not part of …
