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 …

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). …

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 …

2010 Warbonnet Ranch Botanical Survey, Robert F. Steinauer

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Nebraska Natural Legacy Project (Schneider et al, 2005), a statewide comprehensive wildlife conservation strategy developed by the Nebraska Game and Parks Commission (NGPC), identified the Pine Ridge and Oglala Grasslands of northwestern Nebraska as “Biologically Unique Landscapes” (BULs). Native plant community and rare plant surveys were conducted on the approximately 8,000-acre privately-owned Warbonnet Ranch. The Ranch occurs within both of the above mentioned BULs and is topographically and geologically diverse. The primary goal of this survey was to document the botanical resources of a well-managed, privately-owned, western Nebraska range and determine its potential for conservation of Nebraska’s biological diversity. …

Traversing Swanton Road, 2nd Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

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 …

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. …

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 …

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). …

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 …

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.

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 …

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 …

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 …

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 …

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 …

2009 Vascular Plant Surveys In The Central Niobrara River Valley, Nebraska, Mary Ann Feist, Paul B. Marcum, Loy R. Philippe, Brenda Molano-Flores, Valerie Sivicek

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Niobrara River Valley in northern Nebraska is an important floristic area. It harbours a number of bryophyte, vascular plant, and animal species that are rarely found in close proximity to one another. Many of these species are more typical farther to the north, east, or west, but over time as climates have changed, have come to settle together in this valley (Kaul et al. 1988). The central Niobrara River Valley may be the most botanically diverse region of Nebraska. Approximately 580 of Nebraska’s roughly 2,000 vascular plant species have been documented for the Niobrara Valley Preserve (Schneider et al. …

Combining Local- And Large-Scale Models To Predict The Distributions Of Invasive Plant Species, Chad C. Jones, Steven A. Acker, Charles B. Halpern

Botany Faculty Publications

Habitat-distribution models are increasingly used to predict the potential distributions of invasive species and to inform monitoring. However, these models assume that species are in equilibrium with the environment, which is clearly not true for most invasive species. Although this assumption is frequently acknowledged, solutions have not been adequately addressed. There are several potential methods for improving habitat-distribution models. Models that require only presence data may be more effective for invasive species, but this assumption has rarely been tested. In addition, combining modeling types to form ‘ensemble’ models may improve the accuracy of predictions. However, even with these improvements, models …

A Taxonomic Revision Of Orthotrichaceae (Musci) With Contributions To The Biosystematics Of Macromitrium Brid. In Malaysia., Yong Kien Thai

Student Works (2010-2019)

Macromitrium (Orthotrichaceae) is a large genus variously divided into infrageneric groups by different authors, resulting in a complex classification which has not included many Malaysian species. This study reviews the taxonomy of Malaysian taxa and extent of morphological variation in relation to the type group. A molecular phylogenetic study was carried out to determine if Malaysian Macromitrium species represented a homogeneous taxonomic grouping. A cladistic analysis of morphological characteristics was attempted for identifying well-defined groups and their key character states. Molecular studies included Maximum Parsimony and Bayesian Inference analyses of two chloroplast DNA regions (rps4 gene and trnL-trnF interspecific region) …

Taxonomy And Biogeography Of Sundaland Gardenia (Rubiaceae)., Low Yee Wen

Student Works (2010-2019)

In Southeast Asia, the genus Gardenia J.Ellis (Rubiaccae) is poorly understood and documented due to a lack of country revisions, contentious species delimitations and accumulation of poorly identified material in herbaria. This study reviewed the taxonomic history and position of the genus, and revised the taxonomy of Sundaland species (including those of Sumatra. the Malay Peninsula, Java_ Borneo, Palawan and adjacent islands). It includes a survey and cladistic study of morphological characteristics, and phylogenetic ana lyses using two chloroplast regions (atpB-rbcL and trnT-F) and the nuclear ITS region of representative species from Sundaland and adjoining regions. Twelve species are native …

Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge

The Prairie Naturalist

I examined patterns of bison (Bison bison L.) hair use by passerine birds nesting in the Tallgrass Prairie Preserve, Osage County, Oklahoma, 2002-2004. I collected and dissected 103 nests of 15 species into their constituent components. Nests were predominately composed of herbaceous material such as grass stems and leaves. Woody material and mud were rarely used. Bison hair was the most prominent zoological material used in nests, with lesser amounts and occurrence of arthropod silk, snake skin, feathers, jack rabbit (Lepus californicus Oray) fur, and man-made materials such as cellophane and string. At least one nest of 13 …

Long Distance Molt Migration By A Giant Canada Goose From Eastern South Dakota, Bobby J. Anderson, Charles D. Dieter

The Prairie Naturalist

To reduce crop damage by resident giant Canada geese (Schaible et al. 2005), the South Dakota Department of Game, Fish and Parks (SDGFP) initiated a program to reduce goose nesting success in eastern South Dakota. One management tool used by SDGFP personnel was the destruction of giant Canada goose nests. When a giant Canada goose has its nest destroyed, they are known to initiate a molt migration (Mykut 2002, Luukkonen et aI. 2008). We attached Platform Transmitting Terminals (PTT; model ST -19) to document and describe molt migrations of giant Canada geese following nest destruction. We captured 3 adult nesting …

Noteworthy Winter Prey Of Short-Eared Owls In Southern Texas: A Case Study, Damon Williford, Marc C. Woodin, Mary Kay Skoruppa

The Prairie Naturalist

The winter range of North American short-eared owls (Asio flammeus) encompasses much of the United States, including southern Texas, where it is a common winter resident (Oberholser 1974, Rappole and Blacklock 1985). Winter food habits of short-eared owls are relatively weJl documented, but the majority of investigations have been conducted in eastern Canada and northeastern U.S. (Clark 1975, Holt 1993); midwestern U.S. (Colvin and Spaulding 1983); and British Columbia and Pacific northwestern U.S. (Bogiatto et al. 2001). The short-eared owl has a narrow trophic niche, generally preying on small mammals, with voles (Microtus spp.) and deer mice …
