Modeling Parental Provisioning By Red-Winged Blackbirds In North Dakota, George M. Linz, Richard S. Sawin, Mark W. Lutman, William J. Bleier

The Prairie Naturalist

Male red-winged blackbirds (Agelaius phoeniceus) exhibit a difference in nest provisioning rates along an east-west gradient in North America. North Dakota is located in the center of North America and harbors a large population of breeding red-winged blackbirds (RWBL). This location provided an opportunity to compare provisioning rates in the central U.S. with those reported for the eastern and western populations. We placed video cameras at RWBL nests to record male and female feeding trips. Thirty-four nests were located on territories with original males and 30 were on territories where a replacement (floater) male had taken over a …

Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster

The Prairie Naturalist

We conducted an experiment to investigate effects of species, water (W), and nitrogen (N) on competition among little bluestem (Schizachyrium scoparium), sideoats grama (Bouteloua curtipendula), and indiangrass (Sorghastrum nutans). All biomass parameters and the root:shoot ratio of little bluestem were reduced by the presence off 1 of 2 other species, and its shoot biomass and total biomass were both increased by addition of N. Root and shoot biomass of sideoats grama were reduced by the presence of indiangrass and its total biomass was reduced by the presence of itself, whereas its shoot biomass was increased by addition of W at …

Crustaceous Zooplankton Transfer Between A Floodplain Wetland And The Missouri River, Shannon J. Fisher

The Prairie Naturalist

Floodplain interactions are a critical riverine ecosystem function, including zooplankton transfer. Floodplain alternations have had an assumed impact on zooplankton productivity. I assessed floodplain wetland and main channel densities of crustaceous zooplankton, alluding to organism transfer in the Missouri River, North Dakota. Significant t-test differences (P < 0.05) were present between backwater and channel habitat zooplankton densities in 83, 75, 83, and 50% of the sample periods for cyclopoid copepods, copepod nauplii, Daphnia spp., and Bosmina spp. respectively, suggesting the presence of uncoupled zooplankton dynamics during portions of each annual cycle. Two relationships with increased flows were found, including a biologically significant decrease (P = 0.09) of backwater copepod nauplii numbers and a significant increase (P = 0.02) in the channel density of Daphnia spp. During the highest flow periods, fewer significant differences in zooplankton densities were present between the backwater and channel habitats, indicating moderate homogenization.

Notes: River Otters Use Agricultural Field Along The Turtle Riveri In Eastern North Dakota As Crossover And Latrine Area, Maggie D. Triska, Steven C. Loughry, Thomas L. Sergass

The Prairie Naturalist

Recently, the Nearctic river otter (Lontra canadensis) has been re-colonizing portions of eastern North Dakota. The landscape in eastern North Dakota is dominated by agricultural fields and pastures, habitats which have received little research attention related to otter habitat use. During 2008, we searched shorelines to detect otter latrines, which is a common method for determining otter presence. Generally, latrines are locations along bodies of water where otters deposit scats, urine, and glandular secretions for olfactory communication, and groom, wrestle, and play, which may mat vegetation. In the northeastern United States, inland riverine system studies have shown latrines …

Resource Selection By Elk At Two Spatial Scales In The Black Hills, South Dakota, Mark A. Rumble, R. Scott Gamo

The Prairie Naturalist

Understanding resource selection by elk (Cervus elaphus) at multiple spatial scales may provide information that will help resolve the increasing number of resource conflicts involving elk. We quantified vegetation at 412 sites where the precise location of elk was known by direct observation and 509 random sites in the Black Hills of South Dakota during 1998– 2001. We obtained stand level variables from geographic information system coverages for a 250 m buffer around elk and random sites. We used classification and regression trees to simultaneously evaluate environmental thresholds of resources selected by feeding and bedded elk at the site and …

Multiple Bats Entangled On Cactus, Jon C. Pigage, Richard L. Bunn

The Prairie Naturalist

Accidental deaths of bats by entanglement on plants and barbed wire are common (McNicholl 1988, Norquay et al. 2010). It has been hypothesized these incidents involve miscalculations by bats on how close they fly to plants or barbed wire or when chasing insects highly concentrated around vegetation (Norquay et al. 2010). Once the bats hit the plants or barbed wire, they become entangled and or impaled while struggling to free themselves. The earliest reports involved little brown bats (Myotis lucifugus) and unidentified bats entangled on burdock, Arctium sp. (Lyon 1925, Little 1925). Additional reports of bats becoming entangled in plants …

Phragmites Australis In South Dakota: Historical Distribution And Environment, Carol A. Johnston, Kayla L. Miller

The Prairie Naturalist

Common reed, Phragmites australis, has long been a component of Northern Plains wetlands, but impending invasion by the non-native P. australis haplotype M may displace native haplotypes in the future. To increase understanding of historical Phragmites occurrence, we developed a geographic information system (GIS) protocol to improve the georeferencing of specimens from South Dakota herbaria, and mapped the distribution of Phragmites relative to geology, physiographic regions, and water bodies. There were 91 Phragmites herbarium specimens from South Dakota and adjacent Wyoming. Phragmites collections occurred in nearly all physiographic regions of the state, with concentrations occurring in the Prairie Coteau of …

Distribution Of Crayfish Species In Select North Dakota Streams, Cari-Ann Hayer, Terrance L. Velazquez, Mclain S. Johnson, Brian Graeb

The Prairie Naturalist

Crayfish have an integral role in aquatic ecosystems, serving as herbivores, predators, detritivores, and prey for fishes and other aquatic and terrestrial animals (Momot 1995, Taylor et al. 1996, Martin 1997). Many crayfish populations are currently declining as a result of habitat alteration (Taylor et al. 1996) and invasive predators (e.g., rusty crayfish Orconectes rusticus [Girard; Lodge et al. 2000]). Knowledge of crayfish distribution and biology in North America and specifically North Dakota is sparse or lacking (Taylor et al. 1996) and baseline information is necessary to identify effects of anthropogenic alterations. Early inventories documented 3 crayfish species in North …

Assessing The Role Of Conspecific Attraction In Habitat Restoration For Henslow’S Sparrows In Iowa, Jennifer A. Vogel, Rolf R. Koford, David L. Otis

The Prairie Naturalist

The presence of conspecific individuals may provide important cues about habitat quality for territorial songbirds. We tested the ability of a conspecific song playback system to attract Henslow’s sparrows to previously unoccupied restored habitat. We successfully attracted Heslow’s sparrows to 3 of 7 treatment plots using conspecific song playbacks and we found no Henslow’s sparrows in control plots. The addition of social cues using playback systems in restored grassland habitats may aid conservation efforts of Henslow’s sparrows to available habitat.

Calodium Hepaticum In White-Tailed Jackrabbits In South Dakota, Dustin J. Schaible, Charles D. Dieter, Regg D. Neiger, Michael B. Hildreth

The Prairie Naturalist

White-tailed jackrabbits (Lepus townsendii) are common on the prairie, and an important species in prairie food webs (Lim 1987). Although it has been suggested that jackrabbits have cyclic populations (Donoho 1972, Gross et al. 1974, Anderson and Shumar 1986), there is concern that a general downward trend exists in populations in the Northern Great Plains (Feldhamer et al. 2003). Disease incidence in white-tailed jackrabbits is poorly known (Feldhamer et al. 2003), but may be an important factor in population changes. Tularemia, a disease caused by bacteria (Francisella tularensis), occurs throughout the Northern Hemisphere and can affect many mammals including hares, …

Habitat Selection By Female Swift Foxes (Vulpes Velox) During The Pup- Rearing Season, Indrani Sasmal, Jonathan A. Jenks, Troy W. Grovenburg, Shubham Datta, Greg. M. Schroeder, Robert W. Klaver, Kevin M. Honness

The Prairie Naturalist

The swift fox (Vulpes velox) was historically distributed in western South Dakota including the region surrounding Badlands National Park (BNP). The species declined during the mid-1800s, largely due to habitat loss and poisoning targeted at wolves (Canis lupis) and coyotes (C. latrans). Only a small population of swift foxes near Ardmore, South Dakota persisted. In 2003, an introduction program was initiated at BNP with swift foxes translocated from Colorado and Wyoming. We report on habitat use by female swift foxes during the pup-rearing season (May–July) in 2009. Analyses of location data from 13 radiomarked female foxes indicated disproportional use (P < 0.001) of some habitats relative to their availability within swift fox home ranges. Swift foxes used grassland (ŵ = 1.01), sparse vegetation (ŵ = 1.43) and prairie dog towns (ŵ = 1.18) in proportion to their availability, whereas they were less likely to use woodland (ŵ = 0.00), shrubland (ŵ = 0.14), pasture/agricultural-land (ŵ = 0.25) and development (ŵ = 0.16) relative to availability. Swift foxes typically are located in habitats that provide greater visibility, such as shortgrass prairie and areas with sparse vegetation; which allow detection of approaching coyotes (e.g., primary predator of swift foxes).

First Record Of The Least Weasel In The Black Hills Of South Dakota, Tim R. Mullican

The Prairie Naturalist

The least weasel (Mustela nivalis) is a circumboreal species, occurring in North America from Alaska to the Appalachian Mountains (Jones et al. 1983). In the Great Plains, the least weasel recently expanded its range southward through Nebraska (Benedict et al. 2000) and Kansas (Choate et al. 1979, Bailey and Terman 1986) into Oklahoma (Clark and Clark 1988). Also, in recent decades, the least weasel has expanded from eastern and central Nebraska into western Nebraska (Benedict et al. 2000). In South Dakota, least weasels have been previously reported from the eastern 3/4 of the state (Jones et al. 1983, Higgins et …

Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella

Fire Science

Species selection can make the difference between successful revegetation projects and costly failures. Candidate native species for revegetating burned arid lands in the southwestern United States must meet at least two criteria. These species must: (1) be competitive in postfire environments typically dominated by exotic grasses, and (2) be able to become established reliably by seeding or planting. In response to Manager’s Request Task 3 (reestablishment of native vegetation after fires on arid lands) in the 2006 JFS announcement for proposals, this research tackled the problem of selecting native species with the greatest chance of revegetation success by conducting synergistic …

Cropland Nesting By Long-Billed Curlews In Southern Alberta, James H. Devries, Steven O. Rimer, Elizabeth M. Walsh

The Prairie Naturalist

Long-billed curlews (Numenius americanus) are described primarily as a grassland nesting species. However, no studies to date have quantified nest habitat selection among available habitats. During a study of waterfowl nest habitat selection and success in landscapes ranging from cropland to grassland-dominated, we found 9 curlew nests of which 8 were located in active cropland within cropland-dominated landscapes. Cropland nests occurred in fall-seeded winter wheat and spring-seeded barley and nests were clumped in distribution. Four cropland nests and 1 nest in native grass pasture hatched young. Further research is needed to characterize nesting habitat selection and reproductive success …

Reporting Results Of Data Analysis, Preparing Scientific Manuscripts, And Website Development Efforts, Christopher N. Jacques

The Prairie Naturalist

Preparation of scientific manuscripts and use and presentation of statistics have been topics of several commentaries from previous journal Editors-in-Chief, and have been submitted as invited papers, so I would like to share my perspective as the current Editor-in-Chief (Editor) of The Prairie Naturalist (Journal). Because there is not complete consensus among the experts about when hypothesis testing versus information theoretic methods, or Bayesian versus frequentist methods are suitable, previous Editors have avoided presenting their perspectives (Thompson 2010). I also will avoid presenting my perspective as Editor. I will, however, present my perspective on several of these approaches and then …

Population And Diet Assessment Of White Bass In Lake Sharpe, South Dakota, Andrew E. Ahrens, Travis W. Schaeffer, Melissa R. Wuellner, David W. Willis

The Prairie Naturalist

White bass (Morone chrysops) have been introduced into all 4 South Dakota Missouri River reservoirs and compose a substantial proportion of the annual recreational harvest. To date, limited studies have examined white bass population dynamics and food habits in South Dakota Missouri River reservoirs. Our objective was to examine population dynamics and food habits of white bass in Lake Sharpe, a South Dakota mainstem Missouri River reservoir. White bass consistently consumed invertebrates during May but switched to a more piscivorous diet later in the growing season; most of the fish consumed were gizzard shad (Dorosoma cepedianum). …

Correlation Of Mature Walleye Relative Abundance To Egg Density, Jordan D. Katt, Casey W. Schoenebeck, Keith D. Koupal, Brian C. Peterson, W. Wyatt Hoback

The Prairie Naturalist

Knowledge of spawning areas can benefit fisheries management (Marsden et al. 1991). Identification of spawning areas allows managers to protect, enhance, and/or restore critical habitat (Gunn et al. 1996, Thompson 2009), examine important biotic and abiotic conditions necessary for reproduction (Quist et al. 2003), and to efficiently collect broodstock for production (Satterfield and Flickinger 1996). The most effective method to directly identify spawning areas of fish with demersal eggs is to sample the substrate for eggs (Marsden et al. 1991). This method has been used to locate spawning areas of several species (Michaletz 1984, Zorn et al. 1998, Martin 2008). …

Review Of Grouse Of The Plains And Mountains - The South Dakota Story, By Lester D. Flake, John W. Connelly, Thomas R. Kirschenmann, And Andrew J. Lindbloom., Brent E. Jamison

The Prairie Naturalist

Grouse are a fascinating group of birds that offer elaborate breeding displays for birders in the spring, provide sporting opportunities for hunters in the fall, and serve as indicators of grassland health. Though the authors claim that the book targets those who enjoy the outdoors, bird watching, and upland game bird hunting, there is ample reason for ecologists, ornithologists, and grouse researchers to reference this book as well. The book contains general information of interest to a broad audience, but often moves beyond the introductory information to greater detail. Many details are supported by peer-reviewed literature. This book strikes a …

Seasonal Yellow Perch Harvest In Two Dissimilar South Dakota Fisheries, Casey W. Schoenebeck, Michael L. Brown, David O. Lucchesi

The Prairie Naturalist

Angler effort and fish harvest in South Dakota have historically been quantified through summer and winter creel surveys. However, the late-summer, pulsed recruitment of yellow perch (Perea flavescens) into a fishery combined with an increase in fall movement and feeding activity suggested September and October could be significant periods of perch harvest in South Dakota lakes. Seasonal trends in angler effort and yellow perch harvest during 2005-2007 were compared for high- and low-quality yellow perch fishery types commonly found in eastern South Dakota glacial lakes. High-quality yellow perch fisheries are characterized by fast growth (mean total length at age-3 greater …

Summer Activity Pattern And Home Range Of Northern Pocket Gophers In An Alfalfa Field, Jon C. Pigage, Helen K. Pigage

The Prairie Naturalist

AIlocation of time for feeding, resting and reproduction in subterranean animals is difficult to determine. Although pocket gophers (Thomomys spp.) are among the most widely studied subterranean rodents, there are conflicting reports on activity measurement in these animals. Activity studies have included opening gopher burrows (Tryon 1947), laboratory studies of activity (Vaughan and Hansen 1961), telemetry studies (Anderson and McMahon 1981, Bandoli 1987, and Cameron et al. 1988), and subcutaneously implanted radioactive gold wires (Gettinger 1984). The diversity of techniques reflects the difficulty of generalizing results from different species of pocket gophers in natural and artificial environments. Patton and …

Resource Selection Of Greater Prairie-Chicken And Sharp-Tailed Grouse Broods In Central South Dakota, Mark A. Norton, Kent C. Jensen, Anthony P. Leif, Thomas R. Kirschenmann, Gregaory A. Wolbrink

The Prairie Naturalist

Habitat use of sympatric greater prairie-chicken (Tympanuchus cupido) and sharp-tailed grouse (T. phasianellus) broods during the brood-rearing season has not been quantified for stable prairie grouse populations in large contiguous grassland landscapes in the Northern Great Plains. Characteristics of habitats used by prairie grouse broods were described based on data collected from 35 broods (18 greater prairie-chicken and 17 sharp-tailed grottse) during the breeding seasons of 2004 and 2005. Greater prairie-chicken and sharp-tailed grouse broods used vegetation with visual obstruction heights 2:26 cm and 37 cm, respectively. Greater prairie-chicken broods selected western wheatgrass (Pascopyrum smithii …

Current Distribution Of Rare Fishes In Eastern Wyoming Prairie Streams, Christina E. Barrineau, Elizabeth A. Bear, Anna C. Senecal

The Prairie Naturalist

Distributions of native fishes have declined throughout the Great Plains region. Over 50% of native fishes within the Missouri River drainage in Wyoming have experienced declines in distributions. Thus, the primary goal of our study was to assess current distribution of rare native fishes in eastern Wyoming prairie streams. Of the 10 rare fishes sampled, goldeye (Hiodon alosoides), western silvery minnow (Hybognathus argyritis), plains minnow (H. hankinsoni), and Iowa darter (Etheostoma exile) have experienced declines in distribution over the last decade. Plains topminnow (Fundulus sciadicus) appears to be expanding to areas outside …

Examination Of Owl Pellets For Northern Pocket Gophers At Crescent Lake National Wildlife Refuge, Nebraska, Stacey L. Bonner, Keith Geluso

The Prairie Naturalist

Analysis of regurgitated pellets from owls is a well-known and nondestructive method that provides useful information regarding diet (Errington 1930). This technique also is used to examine composition of small mammal communities and distribution of prey species (e.g. Kamler et al. 2003, Torre et al. 2004, Poole and Matlack 2007). In western Nebraska, two species of owls that regularly breed in the region are the common barn owl (Tyto alba) and great horned owl (Bubo virginianus). In the early 1970s, Rickart (1972) studied the diet of both species at Crescent Lake National Wildlife Refuge (CLNWR), Garden …

Population Characteristics Of Central Stonerollers In Iowa Streams, Scott M. Bisping, Jesse R. Fischer, Michael C. Quist, Andrew J. Schaefer

The Prairie Naturalist

The central stoneroller (Campostoma anomalum) is a herbivore that can have substantial effects on algal communities, nutrient dynamics, and energy flow in streams. Despite its importance in lotic ecosystems, little is known about its population dynamics in streams of the Great Plains. Our objective was to describe age structure, age-specific mortality, and growth rates of central stonerollers in three Iowa streams. We sampled fish from 41 reaches during June-August 2007. We sampled 466 central stonerollers, of which we aged 192. Fish varied in length from 32 to 130 mm and in age from age 0 to 4 years. …

Review Of Weeds Of The Midwestern United States & Central Canada, Edited By Charles T. Bryson And Michael S. Defelice, James Stubbendieck

The Prairie Naturalist

This volume is the culmination of work by more than 40 weed scientists and botanists. Its stated purpose is to help identifY the great diversity of weedy and invasive plants that interface with agriculture, industry, and natural ecosystems in central North America. The geographic range covered by this book extends from southeastern Saskatchewan to eastern Kansas, northern Kentucky, northwestern Pennsylvania, and southwestern Quebec. This is a welcome edition because a current book on unwanted plants has not been available for the eastern two-thirds of this region. The book is arranged taxonomically by family and alphabetically by species within each family. …

Diets Of Nesting Swainson's Hawks In Relation To Land Cover In Northwestern North Dakota, Robert K. Murphy

The Prairie Naturalist

Relationships between land use practices and types of prey used by Swainson's hawks (Buteo swainsoni) in the Northern Great Plains is of increasing interest as the quantity and quality of habitat in the region declines. I recorded 1,284 prey items at 18 Swainson' s hawk nesting areas throughout northwestern North Dakota during summer 1986-1987. After correcting for detectability biases and food needs of adults, I estimated (90% CI) 2,087-2,859 total prey individuals and 138.3-206.7 kg of prey biomass (x = 69.8 g/item) were consumed by adult and nestling Swainson's hawks during my study. Major prey (>10% overall …

Comparison Of Two Zooplankton Sampling Gears In Shallow, Homogeneous Lakes, Maude E. Livings, Casey W. Schoenebeck, Michael L. Brown

The Prairie Naturalist

We compared two zooplankton collection gears, Wisconsin nets and column samplers, to evaluate the effectiveness of each gear in quantifying inshore and offshore zooplankton density and size structure in shallow, homogeneous lakes. Zooplankton densities (within gear) did not differ (P > 0.05) between inshore and offshore sites in either study lake, with the exception of Wisconsin-netted Cyclops sp. in Lake Goldsmith. Wisconsin net samples produced a higher mean zooplankton density than column samplers for Bosmina sp., Cyclops sp., and Daphnia sp. in East Oakwood Lake and for Cyclops sp. (inshore), Daphnia sp., and Diaptomus sp. in Lake Goldsmith. Zooplankton densities had …
