Measuring Groundwater–Surface Water Interaction And Its Effect On Wetland Stream Benthic Productivity, Trout Lake Watershed, Northern Wisconsin, Usa, Randall J. Hunt, Mac Strand, John F. Walker Jan 2006

Measuring Groundwater–Surface Water Interaction And Its Effect On Wetland Stream Benthic Productivity, Trout Lake Watershed, Northern Wisconsin, Usa, Randall J. Hunt, Mac Strand, John F. Walker

United States Geological Survey: Staff Publications

Measurements of groundwater–surface water exchange at three wetland stream sites were related to patterns in benthic productivity as part of the US Geological Survey’s Northern Temperate Lakes–Water, Energy and Biogeochemical Budgets (NTL–WEBB) project. The three sites included one high groundwater discharge (HGD) site, one weak groundwater discharge (WGD) site, and one groundwater recharge (GR) site. Large upward vertical gradients at the HGD site were associated with smallest variation in head below the stream and fewest gradient reversals between the stream and the groundwater beneath the stream, and the stream and the adjacent streambank. The WGD site had the highest number …

The U.S. Endangered Species Act (ESA) allows listing of subspecies and other groupings below the rank of species. This provides the U.S. Fish and Wildlife Service and the National Marine Fisheries Service with a means to target the most critical unit in need of conservation. Although roughly one-quarter of listed taxa are subspecies, these management agencies are hindered by uncertainties about taxonomic standards during listing or delisting activities. In a review of taxonomic publications and societies, we found few subspecies lists and none that stated standardized criteria for determining subspecific taxa. Lack of criteria is attributed to a centuries-old debate …


Phylogeography And Spatial Genetic Structure Of The Southern Torrent Salamander: Implications For Conservation And Management, Mark P. Miller, Susan M. Haig, R. Steven Wagner Jan 2006

Phylogeography And Spatial Genetic Structure Of The Southern Torrent Salamander: Implications For Conservation And Management, Mark P. Miller, Susan M. Haig, R. Steven Wagner

United States Geological Survey: Staff Publications

The Southern torrent salamander (Rhyacotriton variegatus) was recently found not warranted for listing under the US Endangered Species Act due to lack of information regarding population fragmentation and gene flow. Found in small-order streams associated with late-successional coniferous forests of the US Pacific Northwest, threats to their persistence include disturbance related to timber harvest activities. We conducted a study of genetic diversity throughout this species’ range to 1) identify major phylogenetic lineages and phylogeographic barriers and 2) elucidate regional patterns of population genetic and spatial phylogeographic structure. Cytochrome b sequence variation was examined for 189 individuals from 72 …


Importance Of Wetland Landscape Structure To Shorebirds Wintering In An Agricultural Valley, Oriane W. Taft, Susan M. Haig Jan 2006

Importance Of Wetland Landscape Structure To Shorebirds Wintering In An Agricultural Valley, Oriane W. Taft, Susan M. Haig

United States Geological Survey: Staff Publications

Only recently has the influence of landscape structure on habitat use been a research focus in wetland systems. During non-breeding periods when food can be locally limited, wetland spatial pattern across a landscape may be of great importance in determining wetland use. We studied the influence of landscape structure on abundances of wintering Dunlin (Calidris alpina) and Killdeer (Charadrius vociferus) observed on wetlands in the agricultural Willamette Valley of Oregon, USA, during two winters (1999–2000, 2000– 2001) of differing rainfall. We examined (1) shorebird use within a sample of 100 km2 regions differing in landscape …


Critical Habitat, J. Michael Reed, H. Resit Akçakaya, Mark Burgman, Darren Bender, Steven R. Beissinger, J. Michael Scott Jan 2006

Critical Habitat, J. Michael Reed, H. Resit Akçakaya, Mark Burgman, Darren Bender, Steven R. Beissinger, J. Michael Scott

United States Geological Survey: Staff Publications

The U.S. Endangered Species Act (ESA) requires that critical habitat-areas essential to the persistence or recovery of a species or population-be identified and protected (Goble and Freyfogle 2002). Despite apprehension that requiring critical habitat designation at the time (or within a year) of listing under the ESA would reduce the rate at which species were listed, this does not appear to have happened (Greenwald et al., this volume; Suckling and Taylor 2006). In fact, critical habitat has been designated for only a fraction of listed species (Scott et al. 2006). Reasons for the poor rate of designation include concerns …


Endangered Species Time Line, Leona K. Svancara, J. Michael Scott, Dale D. Goble, Frank W. Davis, Donna Brewer Jan 2006

Endangered Species Time Line, Leona K. Svancara, J. Michael Scott, Dale D. Goble, Frank W. Davis, Donna Brewer

United States Geological Survey: Staff Publications

The Endangered Species Act (ESA) is embedded in a web of statutes designed to regulate relationships between humans and other species that stretch back nearly a millennium (Goble, this volume; Goble and Freyfogle 2002). This chapter presents a time line of federal actions taken to protect wildlife beginning with passage of the Land and Water Conservation Fund Act in 1963 (Act of May 28, 1963). Earlier laws to protect wildlife are discussed elsewhere (Goble, this volume). The time line emphasizes federal actions that conserve species at risk of extinction and significant events in the course of implementing the Endangered Species …

Environmental Contaminants And Biomarker Responses In Fish From The Columbia River And Its Tributaries: Spatial And Temporal Trends, Jo Ellen Hinck, Christopher J. Schmitt, Vicki S. Blazer, Nancy D. Denslow, Timothy M. Bartish, Patrick J. Anderson, James J. Coyle, Gail M. Dethloff, Donald E. Tillitt

United States Geological Survey: Staff Publications

Fish were collected from 16 sites on rivers in the Columbia River Basin (CRB) from September 1997 to April 1998 to document temporal and spatial trends in the concentrations of accumulative contaminants and to assess contaminant effects on the fish. Sites were located on the mainstem of the Columbia River and on the Snake, Willamette, Yakima, Salmon, and Flathead Rivers. Common carp (Cyprinus carpio), black bass (Micropterus sp.), and large-scale sucker (Catostomus macrocheilus) were the targeted species. Fish were field-examined for external and internal lesions, selected organs were weighed to compute somatic indices, and tissue …


Comparison Of Breeding Bird And Vegetation Communities In Primary And Secondary Forests Of Great Smoky Mountains National Park, Theodore R. Simons, Susan A. Shriner, George L. Farnsworth Jan 2006

Comparison Of Breeding Bird And Vegetation Communities In Primary And Secondary Forests Of Great Smoky Mountains National Park, Theodore R. Simons, Susan A. Shriner, George L. Farnsworth

United States Geological Survey: Staff Publications

We compared breeding bird communities and vegetation characteristics at paired point locations in primary (undisturbed) and mature secondary forest (70–100 years old) sites in Great Smoky Mountains National Park, USA to understand how sites logged prior to creation of the park compare to undisturbed sites following 70 years of protection from human disturbance. We found that bird and vegetation communities are currently similar, but retain some differences in species composition. Rank abundance curves for primary and secondary forest bird communities showed very similar patterns of species dominance. Species composition was also similar on the two sites which shared 24 of …


The Agricultural Productivity Of Chaco Canyon And The Source(S) Of Pre-Hispanic Maize Found In Pueblo Bonito, Larry Benson, John Stein, Howard Taylor, Richard Friedman, Thomas C. Windes Jan 2006

The Agricultural Productivity Of Chaco Canyon And The Source(S) Of Pre-Hispanic Maize Found In Pueblo Bonito, Larry Benson, John Stein, Howard Taylor, Richard Friedman, Thomas C. Windes

United States Geological Survey: Staff Publications

Agricultural productivity estimates suggest that the core area of Chaco Canyon could have sustained only a few hundred individuals. Modern analogues of existing Pueblo populations and their domestic habitations with Chaco structures suggest that Chaco at times had a resident population exceeding 2000 people. These data suggest that maize would have had to be imported to feed permanent residents and those visiting Chaco during ritual–political gatherings and those who participated in the accelerated construction and modification of great houses between AD 1030 and 1130. Comparison of strontium-isotope and trace-element ratios of synthetic soil and natural waters from sites within the …

Can Copyright Lend Its Cinderellaic Magic To Chinese Folklore?, 5 J. Marshall Rev. Intell. Prop. L. 203 (2006), Deming Liu Jan 2006

Can Copyright Lend Its Cinderellaic Magic To Chinese Folklore?, 5 J. Marshall Rev. Intell. Prop. L. 203 (2006), Deming Liu

UIC Review of Intellectual Property Law

Folklore in China is disappearing and facing challenges for its very survival. To salvage folklore in China, some have called for immediate legislative action and proposed the law of copyright or sui generis protection as some potential solutions. However, copyright is traditionally concerned with the creations of individuals rather than the cumulative creations of an ethnic group or region. Furthermore, even sui generis protection, which is better adapted to folklore in theory, could be susceptible in practice to the abuses of private monopolies or state tyranny. Overall, the protection of folklore depends more on a consistent governmental policy of open-mindedness …

I Am My Own Worst Enemy: Problems And Possibilities Of European Foreign Policy Vis-A-Vis The United States, Eric Engle Jan 2006

I Am My Own Worst Enemy: Problems And Possibilities Of European Foreign Policy Vis-A-Vis The United States, Eric Engle

St. Thomas Law Review

The European Union ("EU") implements a Common Foreign and Security Policy. This paper argues EU Foreign policy is incohesive, but growing more cohesive. The EU poses no threat to U.S. interests; however, poses only limited opportunities for U.S. foreign policy because the U.S. has relentlessly pursued a short-sighted and self-destructive foreign policy since 2002. The paper elaborates this thesis by considering institutional actors and historical experiences. Thus, it provides an overview of the institutional structure of the EU Common Foreign and Security Policy, as well as an overview of historic experiences of EC foreign policy.

A Proposed Framework For Visualization To Teach Computer Science, M. Yousoof, M. Sapiyan, K. Kamaluddin Jan 2006

A Proposed Framework For Visualization To Teach Computer Science, M. Yousoof, M. Sapiyan, K. Kamaluddin

Research Publications (2006 to 2010)

Computer programming is considered a very difficult course by many computer science students. The reasons for the difficulties include cognitive load involved in programming, different learning styles of students, instructional methodology and the choice of the programming languages. To reduce the difficulties the following have been tried: pair programming, program visualization, different learning styles etc. However, these efforts have produced limited success. This paper reviews the problem and proposes a framework to help students overcome the difficulties involved.
