Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. Pesticide (EPA …

Evaluating Diet Composition Of Pronghorn In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jaret D. Sievers, Jonathan A. Jenks, Chad L. Sexton, Daniel E. Roddy

The Prairie Naturalist

The pronghorn (Antilocapra americana) was reintroduced into Wind Cave National Park (WCNP), South Dakota, in 1914, and thus, has inhabited the Park for nearly a century. During the 1990's, a decline in the population raised concern for the continued existence of pronghorn inside WCNP; an investigation into the observed decline was initiated. Primary objectives of our study were to evaluate diet composition and forage selection by pronghorn in WCNP. Microhistological analysis was conducted on 58 fecal samples collected opportunistically from pronghorn during 2002. Blue grama (Bouteloua gracilis), common juniper (Juniperus communis), and northern bedstraw …

Evaluation Of Habitat Enhancement Structure Use By Spotted Bass, Stanley L. Proboszcz, Christopher S. Guy

The Prairie Naturalist

Habitat enhancement is a common and effective method used to positively influence fish populations. However, there is a paucity of speciesspecific evaluations of stream habitat enhancement structures for warmwater fishes. We evaluated use of half-log, rootwad enhancement structure, and simulated undercut bank (LUNKERS) by adult and juvenile spotted bass (Micropterus punctulatus) in natural and experimental streams. Enhancement structures were installed in Otter Creek, Kansas. Adult spotted bass use of natural and enhancement structure was documented weekly during summer and fall of 2001 and 2002 with radiotelemetry. Mean total length (TL) of adult fish was 292 mm (SE = …

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore

The Prairie Naturalist

There have been almost no surveys of herpetofauna at 109 km² Lostwood National Wildlife Refuge (LNWR) or surrounding counties in northwestern North Dakota, an area possibly undergoing significant environmental change from fossil fuel extraction and use. We used 30 m drift fences to survey amphibian and reptile species in prairie-wetland transition zones at LNWR during mid-May to early-July in 1985 to 1987, and again in 1999 and 2000. We captured only four amphibian and two reptilian species and noted one other reptilian species incidental to our survey. Several species expected to occur in the area were not detected.

Nebraskans who experience damage and nuisance problems with wildlife can get assistance from several public and private organizations. This NebFact describes the most direct route to the solution of your problem. A reference guide (Table I) lists who to contact for information, materials, permits, and hands-on assistance. Wildlife play an important role in our environment. In addition, we gain many recreational, economic, and aesthetic benefits from them. Unfortunately, the activities of wildlife occasionally conflict with human interests in personal property, agricultural production, and health and safety. The most common wildlife damage and nuisance problems in Nebraska are caused by bats, …

Planning For Robust Reserve Networks Using Uncertainty Analysis, Atte Moilanen, Michael C. Runge, Jane Elith, Andrew Tyre, Yohay Carmel, Eric Fegraus, Brendan A. Wintle, Mark Burgman, Yakov Ben-Haim

School of Natural Resources: Faculty Publications

Planning land-use for biodiversity conservation frequently involves computer-assisted reserve selection algorithms. Typically such algorithms operate on matrices of species presence–absence in sites, or on species-specific distributions ofmodel predicted probabilities of occurrence in grid cells. There are practically always errors in input data—erroneous species presence–absence data, structural and parametric uncertainty in predictive habitat models, and lack of correspondence between temporal presence and long-run persistence. Despite these uncertainties, typical reserve selection methods proceed as if there is no uncertainty in the data or models. Having two conservation options of apparently equal biological value, one would prefer the option whose value is relatively …

Price Elasticity Reconsidered: Panel Estimation Of An Agricultural Water Demand Function, Karina Schoengold, David L. Sunding, Georgina Moreno

School of Natural Resources: Faculty Publications

Using panel data from a period of water rate reform, this paper estimates the price elasticity of irrigation water demand. Price elasticity is decomposed into the direct effect of water management and the indirect effect of water price on choice of output and irrigation technology. The model is estimated using an instrumental variables strategy to account for the endogeneity of technology and output choices in the water demand equation. Estimation results indicate that the price elasticity of agricultural water demand is -0.79, which is greater than that found in previous studies.

Ecophysiology Of Two Native Invasive Woody Species And Two Dominant Warm-Season Grasses In The Semiarid Grasslands Of The Nebraska Sandhills, Kathleen D. Eggemeyer, Tala Awada, David A. Wedin, F. Edwin Harvey, Xinhua Zhou

School of Natural Resources: Faculty Publications

Populations of Pinus ponderosa and Juniperus virginiana are expanding into semiarid Sandhills grasslands in Nebraska. To evaluate the physiological basis of their success, we measured the seasonal course of leaf gas exchange, plant water status, and carbon isotope discrimination in these two native trees and two native C₄ grasses (Schizachyrium scoparium and Panicum virgatum). Compared to the trees, grasses had higher net photosynthetic rates (A_net) and water use efficiency (WUE) and more negative predawn and midday water potentials (Ψ) in June and July. While leaf Ψ and rates of leaf gas exchange declined for all …

Habitat Characteristics Of Spring Blackbird Roosts In East-Central South Dakota, H. Jeffrey Homan, Richard S. Sawin, George M. Linz, William J. Bleier

The Prairie Naturalist

In the northern Great Plains, blackbirds (Icteridae) roost almost exclusively in emergent-dominated wetlands. The physical characteristics of wetland roosts are not well understood. From March 20 to April 20, 1999, we studied 16 wetlands used as blackbird roosts in east-central South Dakota. Six wetlands had major roosts (range: 102,000-298,000 blackbirds); whereas, 10 wetlands had minor roosts (range: 2,010-34,000 blackbirds). Maximum roost size was correlated directly with emergent vegetation area (P = 0.05) and possibly with wetland basin area (P ≤ 0.10). Water depths were greater at used sites within wetlands of major roosts (median = 44 cm) than …

Climate Variability Has A Stabilizing Effect On The Coexistence Of Prairie Grasses, Peter B. Adler, Janneke Hille Ris Lambers, Phaedon C. Kyriakidis, Qingfeng Guan, Jonathan M. Levine

School of Natural Resources: Faculty Publications

How expected increases in climate variability will affect species diversity depends on the role of such variability in regulating the coexistence of competing species. Despite theory linking temporal environmental fluctuations with the maintenance of diversity, the importance of climate variability for stabilizing coexistence remains unknown because of a lack of appropriate long-term observations. Here, we analyze three decades of demographic data from a Kansas prairie to demonstrate that interannual climate variability promotes the coexistence of three common grass species. Specifically, we show that (i) the dynamics of the three species satisfy all requirements of ‘‘storage effect’’ theory based on recruitment …

Blanding’S Turtle (Emydoidea Blandingii): A Technical Conservation Assessment, Justin D. Congdon, Douglas A. Keinath

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Blanding’s turtles (Emydoidea blandingii) are secure in Nebraska, and they range from being vulnerable to threatened, or endangered throughout most of the rest of their distribution. In Region 2, they have not been reported from Kansas, they are extremely rare in South Dakota, and they occupy wetlands in the northern half of Nebraska. The largest population known within the range of Blanding’s turtles is at Valentine National Wildlife Refuge, Nebraska.

The core habitat of Blanding’s turtles has an aquatic component that consists of a permanent wetland and a suite of other, usually smaller and more temporary, wetlands such …

Monitoring Sustainability In Tropical Forests: How Changes In Canopy Spatial Pattern Can Indicate Forest Stands For Biodiversity Surveys, Naikoa Aguilar, Geoffrey Henobry

School of Natural Resources: Faculty Publications

Sustainable management of tropical forests has been identified as one of the main objectives for global conservation and management of carbon stocks. Toward this goal, managers need tools to determine whether current management practices are sustainable. Several international initiatives have been undertaken for the development of criteria and indicators to aid managers in moving toward sustainable practices. Despite these efforts, the question of how to apply and assess indicators remains to be answered from an operational, field-based perspective. Field surveys are expensive and time-consuming when management areas are large and in the face of logistical constraints. Thus, there is a …

Population Biology Of Pumpkinseed In Enemy Swim Lake, South Dakota, Eric J. Weimer, Michael L. Brown

The Prairie Naturalist

Little information is available regarding the biology and population characteristics of pumpkinseed (Lepomis gibbosus), especially in South Dakota, a state at the western edge of the species native range. South Dakota Department of Game, Fish and Parks summer trap net survey data, collected 1998 to 2003, suggests the Enemy Swim Lake population has low abundance (0.4-2.9 per trap net night) and moderately high size structure (proportional stock density [PSD] ranges between 71 and 91). To further examine the biological characteristics of the Enemy Swim Lake population, pumpkinseed was collected from Indian Bay with trap nets during May 2003. …

Reproductive Development In The Sicklefin Chub In The Missouri And Lower Yellowstone Rivers, Douglas J. Dieterman, Eric Roberts, Patrick J. Braaten, David L. Galat

The Prairie Naturalist

We describe aspects of sicklefin chub (Macrhybopsis meeki) reproductive development from three study areas encompassing greater than 2,700 km of the Missouri and Lower Yellowstone rivers. The sicklefin chub was collected between late July and early October in 1996 and 1997. A total of 193 sicklefin chub was collected and examined for reproductive characteristics. Twenty-nine sicklefin chub were found to be reproductively mature females. Some sicklefin chub matured at age 2, but most matured at age 3 and all matured by age 4. Females first became mature at 70 to 79 mm total length (TL) in the Upper …

Brood Break-Up And Juvenile Dispersal Of Lesser Prairie-Chicken In Kansas, James C. Pitman, Brent E. Jamison, Christian A. Hagen, Robert J. Robel, Roger D. Applegate

The Prairie Naturalist

Natal dispersal is critical for genetic interchange between subpopulations of birds and little is known about the timing and extent of lesser prairiechicken (Tympanuchus pallidicinctus) dispersal movements. We monitored movements of 51 transmitter-equipped female lesser prairie-chicken known to have hatched a nest. Average minimum daily brood movements differed (t = -2.94, df = 829, P < 0.01) between the early (273 m; 0 to 14 days post-hatch) and late (312 m; 15 to 60 days post-hatch) brood rearing periods. We captured 71 juvenile lesser prairie-chicken from 10 broods at 3 to 11 days post-hatch and marked them with passive integrated transponder (PIT) tags. We subsequently captured 41 chicks from 20 different broods and fitted them with necklace-style transmitters. Transmitter- equipped brood hens and individual chicks were monitored daily and the average date of brood break-up was September 13 (85 to 128 days post-hatch). Both males and females exhibited bimodal dispersal movements in the fall and spring. Autumn dispersal movements peaked between late October and early November for both sexes. Spring dispersal movement of males peaked during late February. Female dispersal movements in the spring peaked in late March and were much more extensive than fall dispersal movements. Natal dispersal distance for all marked males averaged 1.4 km (SE= 0.2, n = 9). The approximate dispersal distances of three transmitter-equipped females ranged from 1.5 to 26.3 km. Because of greater dispersal distances, females will contribute more to genetic exchanges between fragmented subpopulations. To ensure genetic connectivity, we recommend that a distance of less …

Feeding Habitats Of Spring-Migrating Blackbirds In East-Central South Dakota, Richard S. Sawin, George M. Linz, William J. Bleier, H. Jeffrey Homan

The Prairie Naturalist

Between March 27 and April 21, 1998, we monitored blackbird (Icteridae) activity and habitat selection at a migratory staging area in east-central South Dakota. We used fixed-area observation points located within 20 l-km² circular plots centered on four wetland basins that were used as night roosts. Each roost was surveyed four times, with the surveys spread evenly throughout the blackbird migration. We recorded the number of blackbird flocks, flock size and composition, habitat used, and behavior (e.g., loafing and feeding). Fifty percent (n = 242) of the 482 flocks recorded in the quadrats was observed loafing in trees …
