An Additional Record Of The Ornate Box Turtle From Western South Dakota, Steven G. Platt, Jennifer I. Stover, Edward J. Stover Iii
An Additional Record Of The Ornate Box Turtle From Western South Dakota, Steven G. Platt, Jennifer I. Stover, Edward J. Stover Iii
The Prairie Naturalist
On June 11, 2003, one of us (EJS) found an ornate box turtle crossing BIA Highway 2, approximately 7.2 km north of Sharps Comer on the Pine Ridge Indian Reservation in Shannon County, South Dakota. The air temperature at the time of collection was approximately 30°C and the substrate was moist from light rain the previous day. The turtle was an adult female with a straight-line carapace length of 118 mm. Other straight-line measurements were: maximum carapace width = 100 mm; plastron length = 122 mm; maximum plastron width = 82 mm; and maximum shell depth = 64 mm. We …
The Quintessential Companion For North American Birders: Review Of The Birdwatcher's Companion To North American Birdlife By Christopher W. Leahy, Lawrence Igl
The Prairie Naturalist
The Birdwatcher's Companion was revised in 2004 under a new title, The Birdwatcher's Companion to North American Birdlire, and by a new publisher, Princeton University Press. This substantial work builds on Leahy's previous edition published in 1982. Hailed by the publisher as the quintessential, alphabetically arranged guide to North American birdlife, the new edition of The Birdwatcher's Companion is over 100 pages longer than the first edition, but, overall, the style and format have not changed much between the two editions. The Companion begins with a brief chapter in which the author describes how to use the book, how it …
Factors Influencing Persistence Of White-Footed Mice, Brock R. Mcmillan, Glennis A. Kaufman, Donald W. Kaufman
Factors Influencing Persistence Of White-Footed Mice, Brock R. Mcmillan, Glennis A. Kaufman, Donald W. Kaufman
The Prairie Naturalist
We examined factors that potentially influenced persistence of the white-footed mouse (Peromyscus leucopus) during 1981 to 1988 at Konza Prairie Biological Station, Kansas. We predicted that both abiotic (e.g., precipitation and temperature) and biotic (e.g., availability of food and density of conspecifics) factors would influence persisten~e of individuals at the study site. Persistence of individual white-footed mice on the study site differed among years and seasons. White-footed mice that were first captured in summer or in autumn persisted longer than those first captured in spring. Young females (less than 20 g) had greater persistence than young males, whereas …
Lack Of Brown-Headed Cowbird Nest Parasitism In A Short Grass Region, Stephen L. Winter, Jack F. Cully Jr.
Lack Of Brown-Headed Cowbird Nest Parasitism In A Short Grass Region, Stephen L. Winter, Jack F. Cully Jr.
The Prairie Naturalist
While conducting field work in Morton County, southwestern Kansas and Baca County, southeastern Colorado, during the period 27 May to 2 July 1997, we found 36 nests of seven bird species. Nests were not searched for systematically, but were found coincidentally as data were collected along transects during research investigating the breeding bird and plant communities of black-tailed prairie dog (Cynomys ludovicianus) colonies and noncolonized shortgrass prairie (Winter 1999).
Low densities of the brown-headed cowbird in our study region, which is characterized by a semi-arid climate, might be a consequence of host populations that exhibit extreme temporal and …
Comparison Of Microclimate At Grassland Bird Nests With Different Substrates, Kimberly M. Suedkamp Wells, Samuel D. Fuhlendore
Comparison Of Microclimate At Grassland Bird Nests With Different Substrates, Kimberly M. Suedkamp Wells, Samuel D. Fuhlendore
The Prairie Naturalist
We compared the effects of two different nest placement strategies (shrubs vs. bunchgrasses) on microclimate conditions for grasshopper sparrow (Ammodramus savannarum) and lark sparrow (Chondestes grammacus) in Oklahoma. We predicted that the intensity and duration of extreme temperatures (greater than 39° C) and their variability would be reduced at shrub nests compared to bunchgrass nests. A verage maximum temperatures were similar at nests of grasshopper sparrow and lark sparrow, but confidence intervals were more variable and included biologically detrimental temperatures at grasshopper sparrow nests compared to lark sparrow nests. The proportion of time greater than 39° …
The Sooner State Bird Atlas: Review Of Oklahoma Breeding Bird Atlas, Dan L. Reinking, Editor, Timothy J. O'Connell
The Sooner State Bird Atlas: Review Of Oklahoma Breeding Bird Atlas, Dan L. Reinking, Editor, Timothy J. O'Connell
The Prairie Naturalist
In Oklahoma, forest meets prairie, prairie meets mesa, and throughout, our native ecosystems are shaped by human land use. Across this shifting mosaic of habitats, animals find food, raise young, and disperse to find other members of their species. Management for these species is best informed when it springs from a common baseline of knowledge about distributions across the entire management area. For birds, that baseline can be effectively established with a breeding bird atlas. ... In sum, the Oklahoma Breeding Bird Atlas presents timely information on a fascinating statewide avifauna in a clear and attractive package. The text is …

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
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.
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
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
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
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.
Reproductive Ecology Of Two Common Woody Species, Juniperus Sabina And Artemisia Santolinifolia, In Mountain Steppes Of Southern Mongolia, Katrin Ronnenberg
Reproductive Ecology Of Two Common Woody Species, Juniperus Sabina And Artemisia Santolinifolia, In Mountain Steppes Of Southern Mongolia, Katrin Ronnenberg
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
The present study describes the reproductive ecology of the prostrate shrub Juniperus sabina and the dwarf shrub Artemisia santolinifolia in dry mountain steppes of southern Mongolia. Whereas stands of the juniper are located at the drought limit of the genus’ distributional range, the genus Artemisia is typical of central Asian drylands. Both species produce large numbers of reproductive organs. For Juniperus sabina, however, only 2.5% of the morphologically intact seeds were found to be viable. Correspondingly, neither seedlings nor saplings were found in the field, and recruitment by reseeding happens at most rarely under the present climatic conditions.
Instead, …

Environmental Adaptations Of The Gobi Desert Plants In Mongolia: An Example Of C4-Plants, Ts. Tsendeekhuu, Clanton Candler Black
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
This paper presents the results of our studies on the ecological adaptations and geographical distribution of plants with C4-photosynthesis in Mongolia using 13C isotope discrimination.
Previous studies identified about 80 C4-species in 8 families in the Mongolian flora. Our investigations lead to the identification of four additional species, which can be regarded as C4-plants. Orostachys spinosa (-16.26‰ 13C), O. thyrsiflora (-16.86‰ 13C), O. fimbriata (-16.15‰ 13C), and Euphorbia humifusa (-23.29‰ 13C). However, as the discrimination level for Euphorbia humifusa is very similar to that of C3-plants it may be switching between C3 and C4 types …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
Although two major books have been published on the Mongolian flora regional data are often still lacking due to the vast expanses of the country. Therefore we used published information and data from our own fieldwork to compile a relatively comprehensive inventory of the flora of the Gobi Gurvan Saykhan mountains in southern Mongolia.
First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles
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 …

Response Of Sagebrush Steppe Species To Elevated Co2 And Soil Temperature, Melissa S. Lucash, Blake Farnsworth, William E. Winner
Response Of Sagebrush Steppe Species To Elevated Co2 And Soil Temperature, Melissa S. Lucash, Blake Farnsworth, William E. Winner
Environmental Science and Management Faculty Publications and Presentations
Elevated atmospheric CO2 may cause long-term changes in the productivity and species composition of the sagebrush steppe. Few studies, however, have evaluated the effects of increased CO2 on growth and physiology of species important to this ecosystem. Since the response of plants to elevated CO2 may be limited by environmental factors, soil temperature was also examined to determine if low soil temperatures limit CO2 response. To determine how CO2 and soil temperature affect the growth of species native to the sagebrush steppe, bottlebrush squirreltail [Elymus elymoides (Raf.) Swezey], Thurber needlegrass (Stipa thurberiana Piper), …

Ecological Species Groups Of South Carolina's Jocassee Gorges, Southern Appalachian Mountains, Scott R. Abella, Victor B. Shelburne
Public Policy and Leadership Faculty Research
Ecological species groups, consisting of assemblages of co-occurring plant species exhibiting similar environmental affinities, were developed for ground-flora and tree strata in late- successional forests on a 13,000 ha southern Appalachian landscape. We distinguished 11 ground-flora groups that included 50 species and six tree groups comprised of 19 species. Ground-flora groups ranged from a xeric Vaccinium group (including Vaccinium pallidum, Euphorbia corollata, and Piptochaetium avenaceum) to a mesic Rhododendron group (typified by Rhododendron maximum, Mitchella repens, and Hexastylis heterophylla). Tree groups ranged from a Quercus coccinea group to a Tsuga canadensis group. Consistent with previous research, species groups exhibited a …

Nectar Rewards Of Insect-Adapted Flowers In A Forest/Farm Landscape: Measurement Challenges And Ecological Questions, Theresa Bordenkecher Dailey
All-Inclusive List of Electronic Theses and Dissertations
Native forest wildflowers of the Midwestern United States forests now compete with agricultural weeds for the attention of insect pollinators. The tiny quantities of nectar secreted by these insect-pollinated flowers are measured using laboratory techniques such as colorimetry. However, these techniques are used with the tacit assumption that nectar sugar identity does not affect estimates of carbohydrate content. I tested this hypothesis using fructose, glucose, and sucrose and found that after reaction with anthrone, fructose products differed from those of other sugars in light absorbance measured by a spectrophotometer. Potential error from using an inappropriate sugar standard is greater than …
The Effect Of Prescribed Burns On Cation Exchange Capacity In An Oak Savanna, Christopher Michael Gentry
The Effect Of Prescribed Burns On Cation Exchange Capacity In An Oak Savanna, Christopher Michael Gentry
All-Inclusive List of Electronic Theses and Dissertations
The Indiana Department of Natural Resources estimates that fire-maintained, tallgrass savannas once covered approximately 15% oflndiana. During the 1800's, settlers cleared savannas for their rich soils, which are well suited for agricultural use, and fire was suppressed from the remaining savannas because of the threat to farmland. Today, prescribed bums are being used in savannas as a management tool to reduce competition from non-native species, encourage community density, and promote patch dynamics. This research examines how fire affects Cation Exchange Capacity (CEC) in post fire soil samples. CEC is an important soil characteristic that helps to describe soil fertility. With …
