Arkansas Small-Grain Cultivar Performance Tests 2004-2005, J. T. Kelly, C. E. Parsons, R. K. Bacon

Arkansas Agricultural Experiment Station Research Series

Small-grain cultivar performance tests are conducted each year in Arkansas by the Arkansas Agricultural Experiment Station, Department of Crop, Soil and Environmental Sciences. The tests provide information to companies developing cultivars and/or marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for smallgrain producers.

Influence Of Biocontrol Insects On Canada Thistle: Seed Production, Germinability, And Viability, Gary E. Larson, Tim A. Wittig, Kenneth F. Higgins, Brent Turnipseed, Dawn M. Gardner

The Prairie Naturalist

We conducted surveys of thistle-feeding insects on Canada thistle [Cirsium arvense (L.) Scop.] during the 2000 and 2001 growing seasons at Lacreek National Wildlife Refuge (LNWR), South Dakota, and analyzed their impact on thistle seed production, germination, and viability. Insects included Canada thistle stem weevil [Hadroplontus litura, formerly Ceurtorhynchus lilura, (Coleoptera: Curculionidae)], introduced at LNWR as a biocontrol agent, plus two seed head parasites, the thistle head weevil [Rhinocyllus conicus (Coleoptera: Curculionidae)] and the seed head fly [Terellia ruficauda (Diptera: Tephritidae)]. Infestation by these insects caused no significant reduction in per-head seed yield, with means ranging from 82.5 seeds per …

Christmas Bird Counts For North Dakota 2004, Robert N. Randall

The Prairie Naturalist

Christmas Bird Counts were made in 21 areas in North Dakota again in the year 2004. During the year a new count site was established in Pembina County and registered with the Audubon Society but an actual count was not made in the area this year. The location of the all areas in which counts were actually made is shown in Fig. 1. A relatively mild fall season leading up to the count period left much more open water than normal. Weather conditions during the count period varied widely with some areas reporting temperatures in the 40's and 50's of, …

Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews

The Prairie Naturalist

Nine species of sphecid wasps nesting in sparsely vegetated sandy soils near Ogallala, Keith County, Nebraska were studied during June 2003. The first records of the nest and prey of Cerceris clypeata gnarina Banks and Tachysphex williamsi R. Bohart are presented. Two species of weevils, Baris striata Say and B. subsimilis Casey, were prey of C. clypeata gnarina, with 12 to 22 individuals stocked per cell. Because B. subsimilis is a biological control agent for thistle, this finding is a caution to researchers not to ignore the potential impact of predatory wasps on the community. The single nest of T …

Grazing Intensity Effects On Northern Plains Mixed-Grass Prairie, Wendi M. Rogers, Donald R. Kirby, Paul E. Nyren, Bob D. Patton, Edward S. Dekeyser

The Prairie Naturalist

We evaluated the effects of long-term (1988 to 2000) grazing on northern mixed-grass prairie at tI.e Central Grasslands Research Extension Center in south-central North Dakota. We did not detect a difference in herbaceous basal cover between grazing intensities following 12 consecutive years of season-long moderate (50% removal of annual above-ground standing crop) and heavy (80% removal of annual above-ground standing crop) grazing. However, both moderate and heavy grazing intensities reduced above-ground herbaceous standing crop, total root biomass, and soil organic carbon. Moderate grazing intensity maintained a greater amount of deep (10 to 20 cm) and total root biomass relative to …

Mammals Of Fort Leavenworth, Kansas: A 60-Year Followup To Brumwell (1951), Clay R. Davis, Frederick B. Stangl Jr., Lynn W. Robbins

The Prairie Naturalist

More than 60 years have elapsed since Brumwell's (1951) comprehensive assessment during 193911940 of resident terrestrial vertebrates from Fort Leavenworth Military Rooervation in northeastern Kansas. Subsequent studies have been accomplished for the amphibians, reptiles, and birds. Our study is the first to assess intervening changes in the mammalian composition of this diverse local fauna. Notable observations include: the decline or extirpation of the black-tailed jackrabbit (Lepus californicus), Franklin's ground squirrel (Spermophilus franklinii), muskrat (Ondatra zibethicus), long-tailed weasel (Mustela frenata) and eastern spotted skunk (Spilogale putorius); the return or recovery of locally extirpated gray fox (Urocyon cinereoargenteus), puma (Puma concolor), and …
