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 …

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). …

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 …

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. …

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 …

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 …

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 …

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 …

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 …

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 …

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 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 …

Channel Catfish Diets Include Substantial Vegetation In A Missouri River Reservoir, Jonah D. Dagel, Melissa R. Wuellner, David W. Willis

The Prairie Naturalist

Channel catfish (Ictalurus punctatus) are native to Lake Sharpe, a Missouri River mainstem reservoir, and are common in angler catches. Channel catfish growth has declined since the formation of the reservoir in 1963. Mean lengths at time of capture for channel catfish ages 9, 10, II, and 12 have decreased by 69, 55, 115, and 21S mm, respectively, since impoundment. The objective of this study was to document monthly food habits of channel catfish throughout the growing season (May-August) in Lake Sharpe to assess potential effects of diet on growth. Although channel catfish consumed both macro invertebrates and …

In Situ Development Of Western Prairie Fringed Orchid Seeds, Protocorms, And Seedlings In Grazed And Non-Grazed Prairie Habitat, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser

The Prairie Naturalist

In 1989, the U.S. Fish and Wildlife Service listed the western prairie fringed orchid (Platanthera praeclara) as threatened. Although this orchid has been monitored for years, there is little scientific documentation of its biology, ecology, and phenology, nor the impacts of management activities on its populations. Our objectives were to document seed germination and seedling production rates after one year in situ, and compare seed germination in grazed and non-grazed prairie habitat in the Sheyenne National Grassland (SNG) in southeastern North Dakota. Of 18,717 planted seeds, we recovered 1,561 swollen embryos, 94 protocorms, and 51 seedlings. We documented no difference …

Bat Survey Along The Missouri River In Central South Dakota, Alyssa M. Kiesow, Joshua A. Kiesow

The Prairie Naturalist

ats are efficient predators of night-flying insects (Whitaker 1993), particularly in urban, agricultural, and forested areas in South Dakota (Kiesow 2004). In South Dakota, 6 bat species are considered rare and presently monitored by the South Dakota Natural Heritage Program (SDNHP; South Dakota Natural Heritage Program 2002). Because bats serve a vital ecosystem function there is an increased need to conserve bats and their habitats. Hence, the objectives of this project were to determine bat species richness along the Missouri River in central South Dakota. We conducted surveys of bats using mist-nets and acoustic detection from early May to early …

Use Of Late Season Standing Corn By Female White-Tailed Deer In The Northern Great Plains During A Mild Winter, Troy W. Grovenburg, Christopher N. Jacques, Christopher C. Swanson, Robert W. Klaver, Jonathan Jenks

The Prairie Naturalist

Winter habitat and resource use of white-tailed deer (Odocoileus virginianus) have been studied extensively throughout their northern range. However, limited information exists on deer use of late season standing corn. We evaluated standing corn use by female white-tailed deer on winter range in north-central South Dakota during winter 2005-2006. Results indicate that cover type selection occurred at the population (P < 0.001) and home range (P < 0.001) levels. PopUlation level analysis indicated selection for standing corn (vi> = 4.31) and Conservation Reserve Program (CRP) grasslands (vi> = 2.81). Similarly, at the home range level, deer selected for standing corn (vi> = 1.35) and CRP grasslands (vi> = 1.44). Deer disproportionately increased use of standing corn and CRP …

Evaluating The Impacts Of Black-Tailed Prairie Dogs On Vegetation In Traditional And Non-Traditional Habitats, Erin M. Lehmer, Laurel Hartley, Jesse Lanci, Charlie Kolb

The Prairie Naturalist

The wildland-urban interface (WUI), defined as areas where human development meets undeveloped wildland (Radeloff et al. 2005), is a focal area for humanwildlife interactions in many communities of the western United States, particularly in those areas that have experienced rapid and expansive human population growth. Since 1960, conversion of rural to urban land has more than doubled in the United States (Theobald 2001). The eastern front range of the Rocky Mountains has experienced one of the most rapid urban expansions in the country, with approximately 110,000 hectares of undeveloped rural land being converted to human-developed land every year between 1992 …

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 …

Cattle Grazing Reduces Survival And Reproduction Of The Western Prairie Fringed Orchid, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser

The Prairie Naturalist

QuantifYing impacts of livestock grazing and prairie management strategies on the threatened western prairie' fringed orchid (Platanthera praeclara) is difficult due to the erratic appearance of the orchid above-ground. We monitored above-ground survival of orchids from flowering to mature seed capsule production, comparing plant height, flower numbers, and seed capsule numbers from 2002-2004 in rotationally grazed pastures and non-grazed sites. Orchid survival differed significantly between grazed and non-grazed pastures, with the proportion of plants surviving from flower to capsule production consistently lower in grazed pastures. Mean orchid survival in grazed and non-grazed areas was 40% and 87%, respectively. …

Observations Of Little Blue Herons Nesting In North Dakota, And An Instance Of Probable Natural Hybridization Between A Little Blue Heron And A Cattle Egret, Alisa J. Bartos, Lawrence Igl, Marsha A. Sovada

The Prairie Naturalist

The little blue heron (Egretta caerulea) is native to North America and most commonly breeds along the coast of the southeastern United States and the Gulf of Mexico through Central America and into South America (Rodgers and Smith 1995). In North America, little blue herons rarely nest outside their coastal range. However, nesting has been documented at several locations in the northern plains including Brown, Kingsbury, and Charles Mix counties, South Dakota (Naugle et al. 1996, Tallman et al. 2002); Pope County, Minnesota (Green and Janssen 1975); and possibly in southeastern Saskatchewan (Nero and Lein 1971, Smith et al. 1996). …

Seed Production And Maturation Of The Western Prairie Fringed Orchid, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser

The Prairie Naturalist

A population of threatened western prairie fringed orchid (Platanthera praeclara) was selected in 2004 on the Sheyenne National Grassland in southeastern North Dakota to study seed production and maturation for future use in population viability modeling. We randomly collected 30 seed capsules from the population under a permit from the U.S. Fish and Wildlife Service to: 1) identify capsule parameters that might be correlated with seed number and viability, 2) estimate an appropriate sample size to obtain accurate seed production estimates, 3) quantify seed production and viability per seed capsule, and 4) document temporal patterns in seed embryo …

Ring-Necked Pheasant Nest Parasitism Of Sharp-Tailed Grouse Nests In Southwest North Dakota, Benjamin A. Geaumont, Kevin K. Sedivec, Christopher S. Schauer

The Prairie Naturalist

Numerous investigators have reported observations of ring-necked pheasant (RNP; Phasianus colchicus) eggs in nests of other gamebirds and waterfowl species (Errington and Hamerstrom 1938, Westemeier et al. 1998, Hagen et al. 2002, Krakauer and Kimball 2009). Previously recorded hosts include wild turkey (Meleagris gallopavo; Schmutz 1988), northern bobwhite (Colinus virginianus; Westemeier et al. 1989), greater prairie-chickens (Tyrnpanuchus cupido; Westemeier et al. 1998), and lesser prairie-chickens (T. pallidicinctus; Hagen et al. 2002). The reported occurrence of nest parasitism during these studies has generally been low with the highest reported occurrences found in …

Early Winter Feeding On Elm Bark By Eastern Fox Squirrels Near The Western Range Terminus, Dessa K. Montgomery, Raymond S. Matlack

The Prairie Naturalist

Fox squirrels (Sciurus niger) feed on >30 different types of food across their extensive range ~Korschgen 1981) including tree buds, flowers, fruits, seeds, and, on occasion, bark. For a large portion of the year, fox squirrels rely heavily on tree seeds (Koprowski 1991). For three consecutive years (2007-2009), we observed fox squirrels feeding on bark of elm trees ( Ulmus sp.) on the campus of West Texas A&M University, Canyon, Texas. Squirrels began feeding on bark in late November shortly after leaves had fallen off the trees and continued almost daily throughout the winter. In late February, when …

Potential Importance Of Competition, Predation, And Prey On Yellow Perch Growth From Two Dissimilar Population Types, Casey W. Schoenebeck, Michael L. Brown

The Prairie Naturalist

Our objective was to describe the influence of population dynamics, inter- and intra-specific competition, predation, prey abundance, and prey size structure on yellow perch (Perca flavescens) growth for two perch population types (high-quality and low-quality) commonly found in South Dakota glacial lakes. We selected Lake Cochrane as a low quality yellow perch population and Lake Madison as a high quality perch population. Sunfish (Lepomis spp.) relative abundance was greater (P < 0.05) in Lake Cochrane than Lake Madison, suggesting interspecific competition may have a large influence on yellow perch growth. Indices of available sizes and densities of zooplankton were lower (P < 0.05) in Lake Cochrane than Lake Madison, suggesting that increased competition for large zooplankton may have reduced zooplankton size structure and density. Zooplankton may be a limiting resource in South Dakota glacial lakes when both yellow perch and sunfish are feeding primarily on zooplankton which may explain differences in perch growth rates between population types .

Climatological Factors Influencing Yellow Perch Production In Semi-Permanent Wetlands, Christopher M. Longhenry, Michael L. Brown, Todd R. St. Sauver

The Prairie Naturalist

Climatological factors such as temperature, wind, and precipitation have been reported to affect fish reproduction and recruitment in large lakes; however, little is known about these relationships in shallow, semi-permanent wetlands. We utilized age-O yellow perch (Perca flavescens) aquacultural harvest data to model climate effects on variability of juvenile yellow perch year class strength in semi-permanent wetlands. Overall, March through May precipitation, April air temperature, and a wetland parameter (i.e., intrinsic characteristics) provided the best-supported model. These results potentially indicate that spring weather patterns have an influence on yellow perch year class strength in semi-permanent wetlands.

Vegetation Trends On A Waste Rock Repository Cap In The Northern Black Hills, Andrew C. Korth, Gary E. Larson, Lan Xu, Thomas E. Schumacher

The Prairie Naturalist

We assessed successional trends, long-term vegetation sustainability, and soil surface protection during the 2005-2007 growing seasons on the 32-ha Ruby Gulch Waste Rock Repository cap. The cap consisted of 150 cm of rock and soil covering a polyethylene membrane which in turn covered mining waste rock in order to prevent leaching of heavy metals and acidic water into streams. Following construction in 2003, a contractor applied a grass-forb seed mixture to provide soil-surface protection especially for steeply sloped portions of the cap. In 2005, we established 56, 1-m² plots, and 20, 20-m transects to annually measure canopy cover, basal …
