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 …

Field Evaluation Of Herbicides On Vegetables And Small Fruits 2004, Ronald E. Talbert, Colleen M. Thomas, Brian V. Ottis, Andrew T. Ellis

Arkansas Agricultural Experiment Station Research Series

Herbicide evaluation studies on vegetables and small fruits were conducted in 2004 at the Arkansas Agricultural Experiment Station at Fayetteville, AR, in an effort to evaluate new herbicides, herbicide mixtures, and their application timings for weed control efficacy and crop tolerance. Results of these studies, in part, provide useful information to producers, fellow researchers, the Crop Protection Industry, and the IR-4 Minor Crop Pest Management Program in the development of potential new herbicide uses in vegetable, and fruit.

Field Evaluation Of Herbicides On Rice 2004, Brian V. Ottis, Ronald E. Talbert, Andrew T. Ellis

Arkansas Agricultural Experiment Station Research Series

Herbicide evaluation studies on rice were conducted in 2004 at the Rice Research and Extension Center near Stuttgart, AR, in an effort to evaluate new herbicides, herbicide mixtures, and their application timings for weed control and crop tolerance. Results of these studies, in part, provide useful information to producers, fellow researchers, and the Crop Protection Industry for the potential use of new herbicide programs for successful rice production in Arkansas.

Harmful Garden Plants In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Many garden plants can cause harm. Some are commercially available and very popular; others are no longer readily available but still exist in older gardens; and yet others are favourite indoor ornamentals, cut-flowers, weeds, or even fruit and vegetables that we consume frequently, often without realising that other parts of those same plants are harmful.

It is impractical and unnecessary to remove from our gardens every single plant that could conceivably be harmful. A more sensible approach is to be aware of the potential danger of a particular plant, and then assess how much or how little risk it poses …

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

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.

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

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 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 …

Arkansas Cotton Variety Test 2004, Fred M. Bourland, B. S. Brown, J. M. Hornbeck, R. C. Doherty, W. C. Robertson

Arkansas Agricultural Experiment Station Research Series

The primary aim of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed dealers establish marketing strategies and assists producers in choosing varieties to plant.

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, …

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

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 …

Relationship Among Genes Conferring Partial Resistance To Leaf Rust (Puccinia Triticina) In Wheat Lines Ci 13227 And L-574-1., Jeffery S. Lehman, Karin A. Hanson, Gregory Shaner

Biology and Earth Science Faculty Scholarship

This study describes the segregation of genes for resistance to the fungus Puccinia triticinain a cross between partially resistant wheat lines L-574-1 and CI 13227 with two and four genes for resistance, respectively. The objectives of this study were to use parental, F1, F2, and backcross populations to quantify maternal effects, degree of dominance, and transgressive segregation, and to determine whether CI 13227 and L-574-1 share any resistance genes for long latent period or small uredinia. In two experiments conducted in the greenhouse, the uppermost leaf of adult wheat plants was inoculated prior to heading with P. triticina. On days …

Bloodroot Pollination: Bet-Hedging In Uncertain Times, W. John Hayden

Biology Faculty Publications

“Hurry up and wait.” The phrase that epitomizes life in the military or any other large, bureaucratic, organization, applies surprisingly well to bloodroot and similar ephemeral wildflowers. Each year these plants race to flower as early as possible to assure sufficient time for fruits to ripen and seeds to mature while sunshine is abundant at the forest floor, for all too soon the forest floor will be draped in shadows cast by the trees’ leafy canopy. Ephemerals do everything quickly: sprout, grow, flower, disperse seeds, and re-enter dormancy. But flowering in very early spring can be risky. Some days will …
