Daphnia Lumholtzi, An Exotic Zooplankton, Invading A Nebraska Reservoir, Brian C. Peterson, Nicolas J. Fryda, Keith D. Koupal, Wyatt Hoback

The Prairie Naturalist

A limnological assessment project by the University of Nebraska at Kearney and the Nebraska Game and Parks Commission collected weekly vertical zooplankton tows during May through September 2002 at Harlan County Reservoir in Nebraska. Beginning on 5 August 2002, the exotic Daphnia lumholtzi (Cladocera: Daphniidae) appeared at a density of 0.04 1.1 in one of fifteen standardized sampling stations. By 6 September 2002, D. lumholtzi was found in all fifteen stations at an average density of 2.17 ± 3.10 1.1 with a site maximum density of 11.43 1.1 • Length measurements of D. lumholtzi ranged from 0.80 mm to 5.66 …


Electrocution Of An Adult White-Tailed Deer, Christopher S. Deperno, Benjamin J. Bigalke, Jonathan A. Jenks, Brian S. Haroldson, Robert G. Osborn Mar 2005

Electrocution Of An Adult White-Tailed Deer, Christopher S. Deperno, Benjamin J. Bigalke, Jonathan A. Jenks, Brian S. Haroldson, Robert G. Osborn

The Prairie Naturalist

On 16 May 2002, an adult female white-tailed deer (Odocoileus virginianus) died after becoming entangled in an electric fence in southeast Minnesota. The deer (#393) was captured 30 January 2000 as part of a cooperative, long-term deer mortality study being conducted in southern Minnesota (Bigalke et al. 2002, Brinkman 2003, Brinkman et al. 2002). Although fence entanglements occur, they do not account for significant losses in white-tailed deer populations (Matschke et al. 1984). Nixon et al. (1991) documented mortality of two fawns with broken cervical vertebrae that had collided with fences, but did not distinguish the type of …

Continued Range Expansion Ny The Cave Myotis, Shauna R. Marquardt, Jerry R. Choate, Stanley D. Roth Jr. Mar 2005

Continued Range Expansion Ny The Cave Myotis, Shauna R. Marquardt, Jerry R. Choate, Stanley D. Roth Jr.

The Prairie Naturalist

The cave myotis (Myotis velifer) is a cavernicolous bat that ranges northward from Honduras to the southern Great Plains and southwestern United States. Its known range in the United States includes the states of Kansas, Oklahoma, Texas, Arizona, New Mexico, and small, southern portions of Nevada and California (Fitch et al. 1981, Hayward 1970). The cave Myotis inhabits caves, mines, and buildings, depending on time of year and specific roost requirements (Fitch et al. 1981, Hayward 1970, Kunz 1973, Sparks and Choate 2000). Before European settlement of areas within the range of the cave Myotis, it likely …

Records Of The Eastern Red Bat On The Northern Front Range Of Colorado, Daniel J. Neubaum Mar 2005

Records Of The Eastern Red Bat On The Northern Front Range Of Colorado, Daniel J. Neubaum

The Prairie Naturalist

Although common in deciduous forest throughout the Midwest and east-central states, the eastern red bat (Lasiurus borealis) is rare in Colorado (Armstrong et al. 1994, Fitzgerald et al. 1994). However, this species has the potential to extend its range because belts of eastern deciduous forest habitat have expanded across western prairies and reached the Front Range of Colorado over the last 100 years (Knopf 1986). The eastern red bat ranges from Canada southward across the United States to northeastern New Mexico with most records occurring east of the Continental Divide (Hall 1981, Shump and Shump 1982, Cryan 2003). …


Lesser Prairie-Chicken Use Of Harvested Corn Fields During Fall And Winter In Southwestern Kansas, Gregory C. Salter, Robert J. Robel, Kenneth E. Kemp Mar 2005

Lesser Prairie-Chicken Use Of Harvested Corn Fields During Fall And Winter In Southwestern Kansas, Gregory C. Salter, Robert J. Robel, Kenneth E. Kemp

The Prairie Naturalist

The lesser prairie-chicken (Tympanuchus pallidicinctus) has declined in numbers in Kansas primarily due to the conversion of sand sagebrush (Artemisia .filifolia) prairie to cropland. The lesser prairie-chicken in Finney County, Kansas exists primarily in large fragments of sand sagebrush prairie, and it forages during fall and winter on waste grain in harvested com (Zea mays) fields adjacent to prairie fragments. We used radio-telemetry to monitor lesser prairie chicken locations and found no significant relationship between numbers of bird locations and amounts of waste grain on the ground in harvested com fields. Even the harvested …


2004 Plant Community Field Surveys In Western Nebraska (Final Report), Robert F. Steinauer Jan 2005

2004 Plant Community Field Surveys In Western Nebraska (Final Report), Robert F. Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

These surveys were undertaken to update information on native plant communities and wildlife habitats in western Nebraska to facilitate the development of the Nebraska Game and Parks Commission’s (NGPC) Comprehensive Wildlife Plan. The specific intent of the project was to identify, map, and give quality rankings to large blocks of privately-owned native plant communities within the survey area. In 2004, the surveys focused on Chase, Dundy, Hayes, Hitchcock, and Perkins counties in southwestern Nebraska, and Sioux, Dawes, Box Butte, Morrill and eastern Banner and Scotts Bluff counties in the Panhandle.

Land Evaluation Standards For Land Resource Mapping : Assessing Land Qualities And Determining Land Capability In South-Western Australia, Dennis Van Gool, Peter J. Tille, Geoff Allen Moore

Resource management technical reports

This report describes the standard method for attributing and evaluating conventional land resource survey maps in the south-west agriculture region of Western Australia so that strategic decisions about the management, development and conservation of land resources can be based on the best information available. The standards described are similar to the land suitability assessment (stage one of the two stage) methods described by the Food and Agriculture Organisation (FAO, 1976, 1983).


Monitoring Temporal Change In Riparian Vegetation Of Great Basin National Park, E. A. Beever, D. A. Pyke, J. C. Chambers, F. Landau, S. D. Smith, K. Murray Jan 2005

Monitoring Temporal Change In Riparian Vegetation Of Great Basin National Park, E. A. Beever, D. A. Pyke, J. C. Chambers, F. Landau, S. D. Smith, K. Murray

Life Sciences Faculty Research

Disturbance in riparian areas of semiarid ecosystems involves complex interactions of pulsed hydrologic flows, herbivory, fire, climatic effects, and anthropogenic influences. We resampled riparian vegetation within ten 10-m × 100-m plots that were initially sampled in 1992 in 4 watersheds of the Snake Range, east central Nevada. Our finding of significantly lower coverage of grasses, forbs, and shrubs within plots in 2001 compared with 1992 was not consistent with the management decision to remove livestock grazing from the watersheds in 1999. Change over time in cover of life-forms or bare ground was not predicted by scat counts within plots in …

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel Jan 2005

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel

Fisheries Management Papers

The Minister for Fisheries established this review of open access (wetline) commercial fishery arrangements to provide a more effective management framework for wetline fishing and to complement the recreational initiatives. This must involve the removal of excess fishing capacity, including latent effort, from the fishery and the establishment of a dedicated commercial fishery with clear entry criteria and an appropriate limit on catch in each bioregion. However it must be made clear that the ‘wetline review’ is not a sectoral resource sharing exercise. Following the implementation of new management arrangements for the ‘wetline’ fisheries, the appropriateness of the existing levels …

Proposed Management Arrangements For The Gascoyne Commercial 'Wetland' Fishery. A Discussion Paper., West Coast And Gascoye Wetline Review Management Planning Panel.

Fisheries Management Papers

The ‘Wetline Review’ was established to implement an effective management framework for the commercial sector to complement the recreational initiatives. It must be stressed at the outset that this review is focussed on the take of scalefish by the commercial sector. The existing levels of use between the various user groups in the Gascoyne will be examined under the new integrated fisheries initiative following the implementation of new management arrangements for scalefish taken by the commercial sector.

Characterizing Moisture Regimes For Assessing Fuel Availability In North Carolina Vegetation Communities, Roberta A. Bartlette, James Reardon, Gary M. Curcio Jan 2005

Characterizing Moisture Regimes For Assessing Fuel Availability In North Carolina Vegetation Communities, Roberta A. Bartlette, James Reardon, Gary M. Curcio

Joint Fire Science Program Research Project Reports

In the southeastern United States prescription burning, fire danger rating and wildfire suppression strategies are constrained by limited knowledge of the influence of moisture content in live vegetation, organic soils, water table and weather. The interactive influence of these factors on fire behavior is not well studied. The 3+ year long study reported here was conducted to gain direct empirical understanding of seasonal fuel and soil moisture dynamics in shrub-dominated pocosin communities, in coastal Virginia and North Carolina, mixed hardwoods communities containing significant laurel and rhododendron understory fuels in western North Carolina and eastern Tennessee, and longleaf pine communities in …


Fuel Reduction And Restoration Of Pine/Hardwood Ecosystems Severely Impacted By The Recent Southern Pine Beetle (Dendroctonus Frontalis) Epidemic In The Southern Appalachians, James M. Vose, Katherine J. Elliott Jan 2005

Fuel Reduction And Restoration Of Pine/Hardwood Ecosystems Severely Impacted By The Recent Southern Pine Beetle (Dendroctonus Frontalis) Epidemic In The Southern Appalachians, James M. Vose, Katherine J. Elliott

Joint Fire Science Program Research Project Reports

As a result of this most recent SPB epidemic (1999-2003), thousands of hectares of dead pine trees have created wildfire-hazard conditions in the southern Appalachians. One of the challenges for land managers is how to return fire to these ecosystems after (1) nearly a decade of exclusion, and (2) the more recent SPB mortality enhanced fuel loads. Higher fuel loads have the potential to increase fire intensity and severity. At the extremes, fires of high intensity and severity can have a large effect on ecosystem structure and function. The objectives of our research were: (1) to quantify fuel load reduction …

An Inventory Of Rangelands In Part Of The Broome Shire, Western Australia, W E. Cotching

Technical Bulletins

The inventory of rangelands in part of the Broome Shire in Western Australia was undertaken by DAFWA between 1989 and 1990. It describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The survey of part of the Broome Shire …


First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles Jan 2005

First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles

The Prairie Naturalist

The evening bat (Nycticeius humeralis) occurs throughout the eastern and southeastern United States and into extreme northeastern Mexico, approximately 42° to 18° N latitude (Watkins and Shump 1981). Although records of females are common, records of adult male evening bats are rare in the northern portion of the species range (Watkins 1969, Watkins 1972). Jones et al. (1967) suggested that adult males might not accompany females to at least some parts of the parturient range. As part of a larger study (Davis 2003) we surveyed bats on Fort Leavenworth Military Reservation (FLMR), Leavenworth County, Kansas in July 2002 …


Grassland And Woodland Bird Occurrence And Habitat Selection In The Prairie-Forest Transition Zone Of Minnesota, Thomas Robert Cooper Jan 2005

Grassland And Woodland Bird Occurrence And Habitat Selection In The Prairie-Forest Transition Zone Of Minnesota, Thomas Robert Cooper

Electronic Theses and Dissertations

Numerous species of woodland and grassland nesting birds have experienced population declines in the midwestern United States. Habitat loss and habitat fragmentation are suspected to be two of the underlying causes for the population declines of woodland and grassland birds. The Minnesota Valley Wetland Management District (WMD) covers 14 counties in southeastern Minnesota in the transition zone between forested and prairie ecoregions. Little information is available relative to which birds are using grassland or woodland habitat within the WMD and how their presence or absence is related to the available habitat conditions. Therefore, my study objectives were to: 1) determine …


The Use Of Discontinuities And Functional Groups To Assess Relative Resilience In Complex Systems, Craig R. Allen, L. Gunderson, A. R. Johnson Jan 2005

The Use Of Discontinuities And Functional Groups To Assess Relative Resilience In Complex Systems, Craig R. Allen, L. Gunderson, A. R. Johnson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

It is evident when the resilience of a system has been exceeded and the system qualitatively changed. However, it is not clear how to measure resilience in a system prior to the demonstration that the capacity for resilient response has been exceeded. We argue that self-organizing human and natural systems are structured by a relatively small set of processes operating across scales in time and space. These structuring processes should generate a discontinuous distribution of structures and frequencies, where discontinuities mark the transition from one scale to another. Resilience is not driven by the identity of elements of a system, …


Factors Affecting Regional Variation In Growth Of Channel Catfish, Bart W. Durham, Kevin L. Pope, Gene R. Wilde Jan 2005

Factors Affecting Regional Variation In Growth Of Channel Catfish, Bart W. Durham, Kevin L. Pope, Gene R. Wilde

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We related the length at age of channel catfish Ictalurus punctatus, an indirect measure of growth, to three climatic and five morphoedaphic variables in 144 Texas reservoirs. Growth of channel catfish ages 3 through 6 was negatively related to longitude, a factor that explained as much as 34% of the variation in length at age. Channel catfish length at age was not significantly related to latitude, conductivity, morphoedaphic index, mean depth, and maximum depth in all age-classes. Among age-7 channel catfish, length at age was positively related to reservoir area, which explained 35% of the variation in growth. A …

Effects Of Human Disturbances On The Behavior Of Wintering Ducks, Melissa L. Pease, Robert K. Rose, Mark J. Butler Jan 2005

Effects Of Human Disturbances On The Behavior Of Wintering Ducks, Melissa L. Pease, Robert K. Rose, Mark J. Butler

Biological Sciences Faculty Publications

Human activity causes wintering waterfowl to expend energy to avoid humans at a time in their annual cycle when energy conservation is important to survival, migration, and breeding reserves. Understanding the effects of recreational activities on waterfowl is important to managing natural resource areas where migratory birds depend on wetland habitat for resting and feeding. We investigated responses of 7 species of dabbling ducks to 5 different experimental human activities, (a pedestrian, a bicyclist, a truck traveling at 2 different speeds, and an electric passenger tram). Responses of ducks depended on type of disturbance, species, and distance from disturbances. Most …

The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff, Jan Nystrom Dec 2004

The Other Side Of Silence: Rachel Carson’S Views Of Animals, Marc Bekoff, Jan Nystrom

Animal Welfare Collection

The publication of Rachel Carson’s Silent Spring in 1962 is widely regarded as one of the major events that launched the modern environmental movement. Silent Spring is a compelling blend of stories, natural history, human values, and biological facts. In this essay we consider Carson’s attitude toward animals in Silent Spring and in other texts. Despite the facts that she was raised to love Nature and animals, little direct attention has been given to Carson’s views about our moral responsibilities to, and the moral standing of animals. Carson favored responsible stewardship, was more of an animal welfarist and environmentalist/conservation biologist …
