Effects Of Compost On Prairie Seedling Establishment And Seed Production, Thomas R. Rosburg, Emiy Sibigtroth, Adam Palmer

The Prairie Naturalist

Compost is a commonly used soil amendment in horticultural and agricultural practices that is generally known to improve soil conditions and plant growth. We conducted a field experiment to investigate the application of compost to prairie production plots as a method to improve seedling establishment and growth and the seed production of established plants. We evaluated the effect of compost depth and tillage on the survivorship, growth, reproduction and ecophysiology of several prairie plant species commonly used in restoration. Results were mixed; for some species, transplants in compost–amended plots incurred lower survivorship and reduced growth compared to control plots. When …

Reproductive Failure In Largeleaf Wild Indigo In A Restored Prairie In Southeastern Minnesota, Neal D. Mundahl

The Prairie Naturalist

Native prairie restorations in many regions of the United States have been hindered by various herbivores consuming plant reproductive parts or products. I conducted field studies of a population of largeleaf wild indigo (Baptisia lactea) on a restored prairie in southeastern Minnesota during the growing seasons of 2010–2012 to determine the cause(s) of repeated reproductive failure. I assessed plants for browsing damage caused by white-tailed deer (Odocoileus virginianus) during the period of flowering and with a deer exclosure experiment involving caged and non-caged plants. I compared reproductive output (numbers of seed pods, viable seeds) of caged …

Association Of Soil Conditions And Grass Species With Variable Cover Of Leafy Spurge, Terence P. Mcgonigle, Jeremy L. Timmer

The Prairie Naturalist

Variation in soil conditions and grass cover was assessed across a range of leafy spurge (Euphorbia esula L.) cover values on a sandy rangeland in Manitoba, Canada. Soil conditions varied by site but not in relation to cover of leafy spurge. We observed a significant negative relationship between total grass cover and increasing cover of leafy spurge. Only porcupine grass (Hesperostipa spartea [Trin.] Barkworth) had a negative relationship with leafy spurge, falling from high cover at low weed occurrence to only trace levels at the highest leafy spurge abundance. Neither prairie Junegrass (Koeleria macrantha [Ledeb.] Schult.), rough …

Soil Chemical Responses To Fire Seasonality And Frequency In A Texas Grassland, Domingo M. Jariel Jr., R. James Ansley, Betty A. Kramp, David L. Jones

The Prairie Naturalist

On a clay-loam mixed grassland dominated by honey mesquite (Prosopis glandulosa Torr.) in northern Texas, we quantified soil pH, soil organic carbon (OC), electrical conductivity (EC), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sodium (Na), zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu) in response to various effects of summer and winter fire treatments from 1991–1996. We conducted summer fire between August and September, and winter fire between January and March. Treatments that included summer fires increased soil pH, EC, Na, and Cu and temporarily decreased soil OC and Mn (P ≤ 0.05). The winter fire treatment …

Venturing Through The Tall Grass: Experiencing The Manitoba Tall Grass Prairie Preserve, Christie L. Borkowsky, Erin Zahradka

The Prairie Naturalist

The Manitoba Tall Grass Prairie Preserve (hereafter the Preserve) was established in 1989 with a goal of protecting a vanishing habitat and to educate the general public of the importance of native grasslands (M. Latta, Nature Manitoba, personal communication). Starting in the early 1990s, an annual Prairie Day event was organized in early August to provide a means of interaction between prairie enthusiasts, the general public and local residents. Self-guiding interpretive trails with rustic amenities were established in 1996 and 2004. School programs, tours, and a simple two-page newsletter have been used to promote the Preserve and bring out visitors …

Notes: Oriental Bittersweet In Grasslands Near Eastern Bluebird Nest Boxes, Neal D. Mundahl

The Prairie Naturalist

Oriental bittersweet (Celastrus orbiculatus Thunb.; hereafter OB) is an invasive, woody vine that has been expanding its range westward in North America since its introduction from East Asia in the mid-1700s for horticultural purposes (Albright et al. 2009, United States Department of Agriculture [USDA] 2012). Although typically a woodland problem in the United States (McNab and Meeker 1987), OB can invade grassland habitats (Fike and Niering 1999), likely sprouting from seeds dropped by birds and mammals (McNab and Meeker 1987, Greenberg et al. 2001, Sarver et al. 2008) and often developing into large, shrub-like tangles of intertwining stems (Fike …

Potential Impacts Of Bison Wallows On A Restored Tallgrass Prairie Community, Kimran Miller, Johanna Foster, Kristen Nielsen, Mary O'Loughlin

The Prairie Naturalist

When bison (Bos bison) repeatedly roll on the ground, they denude vegetation and create wallows (semi-permanent bare areas) that alter the native prairie plant community. Responses to these wallow-related disturbances are not as well documented in restored prairies. From 1 June to 1 September 2010 and from 3 June to 6 August 2011, we examined potential responses at Neal Smith National Wildlife Refuge, a restored prairie with resident bison. We hypothesized that plants and beetles would vary along a disturbance gradient. Our predictions were: (1) near wallows, plants with weedy lifestyles would have highest cover and biomass compared …

Manitoba Tall Grass Prairie Preserve: Providing Habitat For Protected And Provincially Rare Species, Christie L. Borkowsky

The Prairie Naturalist

The establishment of the Manitoba Tall Grass Prairie Preserve in 1989 secured some of the largest and highest quality parcels of tall grass prairie remaining in the province. Shortly after securement by either Nature Manitoba (formerly Manitoba Naturalists Society) or Manitoba Habitat Heritage Corporation, seasonal staff from the Critical Wildlife Habitat Program (CWHP) began inventory efforts to document the various floral and faunal species occurring on these acquisitions. With the addition of the Nature Conservancy of Canada to the Preserve partnership, the Preserve has grown in size to nearly 5,000 ha. The list of species identified on the Preserve has …

A Floristic Survey Of Selected Sites In The Loup River Valley, Nance County, Nebraska, Diane M. Flynn, Steven J. Rothenberger

The Prairie Naturalist

The Loup River Valley of Nebraska contains natural, undisturbed wet meadows with significant plant diversity. Even though these sites are infrequent and are often intermixed with heavily grazed pastures or cultivated fields, they support numerous plant and animal species that do not occur elsewhere. We surveyed three study sites (an ungrazed wet meadow; a grazed wet meadow; and a riparian area) that totaled approximately 68.8 ha during the 2010 and 2011 growing seasons. We compiled an annotated vascular plants checklist for the study area that included 244 plant species of which about 49% (119) were new county records. The mean …

The Prairie Naturalist

Project Prairie began in 2011 as a curriculum-linked integrated environmental studies program to showcase the Rice Lake Plains (RLP), a tallgrass prairie landscape of sandy rolling hills located at the eastern extent of the Oak Ridges Moraine in southern Ontario. Project Prairie provides educators both indoor and outdoor activities that support their curriculum and share the story of the RLP. Project Prairie provides teacher and student resources that focus on the RLP from the mid-nineteenth century to present day. Learning objectives of Project Prairie are developed from the subjects of science, social science, language arts, geography, history, and Aboriginal culture. …

Water Use And Water Tolerance In The Riparian Species American Sycamore (Plantanus Occidentalis L.) And How Its Physiology Compares To The Coexisting Black Willow (Salix Nigra Marshall), Eric Duncan

Dissertations, Theses and Capstone Projects (Full IR Collection)

This study set out to compare aspects of water use and tolerance to inundation and drought of two riparian tree species, Platanus occidentalis L. and Salix nigra Marshall. The main goal of the study was to better understand the two species and assess the suitability of P. occidentalis for use in riparian restoration. To accomplish this, potted individuals were subjected to treatments of drought, inundation, or control, under greenhouse conditions, and separately, in order to estimate water use in trees, season-long diurnal measurements of sap flux (using Granier type thermal dissipation probes) were determined in situ for trees growing in …

Sauger Life History In The Lower Portion Of The Upper Mississippi River, Kasey L. Yallaly, Justin R. Seibert, Sara J. Tripp, David P. Herzog, Quinton E. Phelps

The Prairie Naturalist

Widespread declines have been observed in numerous riverine fish species due to a host of anthropogenic related perturbations such as channelization, dam creation, and exploitation (Graham 1997, Gerken and Paukert 2009). Understanding life history and population demographics of riverine fishes is critical to their conservation. Specific to our study, the Mississippi River has undergone extensive habitat modifications that have changed the Upper Mississippi River (UMR) from a typical lotic large, free flowing river to multiple reservoir-like pools with reduced flow (LePage 1980, Hurley et al. 1987). These habitat transformations may impact sauger (Sander canadensis) populations within the Mississippi River. Several …

Den Characteristics Of Upland And Low- Land Striped Skunks Along The Missouri River Floodplain, Dave Sempek, James A. Wilson

The Prairie Naturalist

Striped skunks (Mephitis mephitis) are opportunistic with respect to habitat use (Bixler and Gittleman 2000), inhabiting an array of landscapes in the proximity of a permanent water supply, such as forest borders, old-fields, fencerows, and open grassy fields broken by wooded ravines (Schwartz and Schwartz 1981, Larivière and Messier 2000). Food quantity and accessibility are major factors determining the quality of striped skunk habitat (Larivière et al. 1999) and are important in the den site selection.

Dens play an important role in skunk survival and reproduction due to the warmth, predator protection, and safe location for parturition they provide (Hwang …

Precipitation And Fire Impacts On Small Mammals In Shortgrass Prairie, Whitney J. Priesmeyer, Raymond S. Matlack, Richard T. Kazmair

The Prairie Naturalist

The southern Great Plains and the northern part of the Texas Panhandle have received less attention from a biological perspective than other parts of the state. Although there is substantial information on the effects of fire on small mammals in the tallgrass and mixed-grass prairies, there is a lack of understanding of fire influences in the shortgrass prairie, specifically on small mammals. We conducted our study on the Cross Bar Cooperative Management Area (CMA), a 4,856 ha shortgrass prairie within the Texas panhandle. Our objective was to determine the effect of three different fire return frequencies and precipitation on diversity …

Bobcat Predation On Bighorn Lamb In The Western Black Hills Of South Dakota, Brynn L. Parr, John Kanta, Joe Sandrini, Daniel J. Thompson, Jonathan A. Jenks

The Prairie Naturalist

Bighorn sheep (Ovis canadensis) are found throughout western North America (Krausman et al. 1993, Goodson 1994, Krausman et al. 1996, Besser et al. 2012). In their current range, commonly documented large predators of bighorn sheep include cougars (Puma concolor), gray foxes (Urocyon cinereoargenteus), wolves (Canis lupus), and coyotes (C. latrans; Ross et al. 1997, Neale et al. 1998, Corti and Shackleton 2002, Dekker 2009, Karsch et al. 2013). Bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) also have been documented as predators to both wild and domestic sheep (Kennedy 1948, Cunningham 1970, Nette et al. 1984, Watte and Phillips …

The Role Of Reviewer Criticism And How To Keep It In Perspective, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! Hopefully this editorial finds you well and gearing up for the summer field season. As I write this editorial, I find myself reflecting on my time as Editor-in-Chief of TPN over the past 5 years. The experience has been personally and professionally rewarding in many ways, and I want to spend some time discussing something that I have experienced not only as a fellow author and Associate Editor, but also as a journal Editor.

Reviewer criticism. Thinking back to when I was appointed Editor, how I viewed criticism then is very different than how I think about …

The Gamekeepers: Wisconsin Wildlife Conservation From Wcd To Cwd. David L. Gjeston., Carrol L. Henderson

The Prairie Naturalist

Author David L. Gjeston has done a masterful job of capturing the history of wildlife conservation and, in particular, the work of the Wisconsin Department of Natural Resources (formerly the Wisconsin Conservation Department or WCD) in protecting, restoring, and managing the wildlife resources of Wisconsin. Gjeston took on an incredibly complex task. He tells a fascinating story of wildlife conservation comprised of many layers of wildlife management from over a century and a half of evolving perceptions regarding wildlife uses, exploitation, restoration, problems, conflicts, and recreational opportunities that continue to the present.

Perhaps the most appealing part of this book …

Quantifying Differences In Habitat Use Between Anglers And Large Bluegills, Eric J. Weimer, Michael L. Brown, Brian G. Blackwell

The Prairie Naturalist

We compared the habitat use of large (>200 mm) bluegills (Lepomis macrochirus) to the locations of anglers targeting bluegills in a South Dakota glacial lake to determine whether habitat use was similar between anglers and bluegills. Eighty- five bluegills (mean total length = 213 mm) collected in September 2002 and May 2003 were affixed with external radio transmitters and subsequently relocated three to four times per week from October 2002 through October 2003. Bluegill angler locations were recorded during bluegill tracking sessions and roving creel surveys. Habitat variables (water depth, vegetation density and height, and substrate type) were measured …

Mammals Of North Dakota. First Edition. Robert Seabloom., Erin H. Gillam

The Prairie Naturalist

As a mammalogist living in the Great Plains, I was excited to hear about the publication of The Mammals of North Dakota by Robert Seabloom. No such field guide has been compiled since the late 1920s, leaving nature lovers and researchers alike without a modern source of information about the mammals of the state. Despite my enthusiasm, I will admit that I was originally expecting a standard (i.e., boring) field guide with dry facts about the taxonomic groups of interest. Much to my surprise, this book was not a mere list of relevant information, but an engaging work providing extensive …

Diurnal Raptors Of Buffalo County, Nebraska, Thomas L. Freeman

The Prairie Naturalist

Diurnal birds of prey are apex predators, which often are utilized as indicators of potential environmental change (Newton 1979, Rodriguez-Estrella et al. 1998). While the Platte River Valley of Nebraska and the central plains are recognized as important winter habitat for numer- ous bird of prey species (United States Fish and Wildlife Service [USFWS] 1981, Root 1988), there are few published studies describing the distribution and abundance of raptors in Nebraska (Mathisen and Mathisen 1968, Craighead and Craighead 1969, USFWS 1981). In addition, studies summarizing the long-term distribution or density of Falconi- formes in Nebraska are limited due to the …

Book Reviews: Video Surveillance Of Nesting Birds. Edited By Christine A. Ribic, Frank R. Thompson Iii, And Pamela J. Pietz., Marissa A. Ahlering

The Prairie Naturalist

Observations and studies of nests have been a central component of ornithology since its inception. Until recently, studies of nesting ecology were limited to human observation, making some types of information nearly impossible to obtain, such as nocturnal behavior, or difficult to study with adequate sample sizes, such as provisioning behaviors or cause of nest failure. The use of video photography to study the nesting biology of birds has exploded in the past decade, and the most recent volume of Studies in Avian Biology, Video Surveillance of Nesting Birds, has done a nice job of summarizing the history of camera …

Mate Replacement And Alloparental Care In Ferruginous Hawk (Buteo Regalis), Shubham Datta, Will M. Inselman, Jonathan A. Jenks, Kent C. Jensen, Christopher C. Swanson, Robert W. Klaver, Indrani Sasmal, Troy W. Grovenburg

The Prairie Naturalist

Alloparental care (i.e., care for unrelated offspring) has been documented in various avian species (Maxson 1978, Smith et al. 1996, Tella et al. 1997, Lislevand et al. 2001, Literak and Mraz 2011). A male replacement mate that encounters existing broods has options, which include alloparental care or infanticide. Infanticide may be beneficial in some species (Rohwer 1986, Kermott et al. 1990), but in long-lived avian species, like the ferruginous hawk (Buteo regalis) that do not renest within a season, infanticide might be detrimental. Adoption and rearing success likely provide direct evidence of competence of replacement mates as potential parents for …

Multi-Scale Habitat Use Of Male Ruffed Grouse In The Black Hills National Forest, Cassandra L. Mehls, Kent C. Jensen, Mark A. Rumble, Michael C. Wimberly

The Prairie Naturalist

Ruffed grouse (Bonasa umbellus) are native upland game birds and a management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest (Black Hills). Our objective was to assess resource selection of male ruffed grouse to identify the most appropriate scale to manage for aspen and ruffed grouse in the Black Hills. During spring 2007 and 2008, we conducted drumming surveys throughout the central and northern Black Hills to locate used and unused sites from which we compared habitat characteristics at increasing spatial scales. Aspen with >70% overstory canopy cover (OCC) was important to the occurrence of …

Making Nature Whole: A History Of Ecological Restoration. William R. Jordan Iii And George M. Lubick., Daryl D. Smith

The Prairie Naturalist

Ecological restoration—the process of assisting the recovery of ecosystems that have been degraded, damaged, or destroyed—is being incorporated into the fabric of our society. The practice of ecological restoration of natural areas developed and grew in the twentieth century in response to widespread human disturbance of natural communities. Undoubtedly, this type of restoration will continue to increase in importance in the coming decades given the extensive alteration of ecosystems that is occurring and that is showing no signs of abating.

As indicated in the promotional material for Making Nature Whole, Jordan and Lubick have provided a seminal publication for the …

Notes: Bed-Site Selection By Neonatal White-Tailed Deer In Central North Dakota, Brian A. Schaffer, Jonathan A. Jenks, Troy W. Grovenburg, William F. Jensen

The Prairie Naturalist

Understanding bed-site selection and vegetation characteristics provides valuable information for population management (Verme 1977, Huegel et al. 1985a, Nelson and Woolf 1987). Predation and other natural-caused mortalities of white-tailed deer (Odocoileus virginianus) neonates are most likely to occur within the first 60 days of life; a time period when selected habitat characteristics are vital to survival (Verme 1977, Hue- gel et al. 1985a, Nelson and Woolf 1987, Grovenburg et al. 2010). Prior to the study of Grovenburg et al. (2010), limited research had been completed on the bed-site selection of neonatal white-tailed deer in the grasslands of the Northern Great …

Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell

National Invasive Species Council

Conclusion

The success of any harvest incentive program to address aquatic invasive species will depend upon numerous biological, socioeconomic, and legal considerations. Programs that encourage harvest may be a successful management tool in targeting small, distinct populations; in high priority areas within a larger invasion; or they may play a supplementary role within larger control programs. Their use, however, will require careful review, planning, and monitoring to ensure success and that they do not unintentionally lead to further spread of invasive species, cause additional harm to native species, or waste valuable resources.

Root Growth Of Two Perennial Grass Types And Musk Thistle (Carduus Nutans) In Temperate Grasslands Of North America, Chengchou Han, Stephen L. Young

West Central Research and Extension Center, North Platte

Root architecture of prairie grasslands, which depends on plant phenology and edaphic conditions, strongly influences susceptibility to invasion by nonindigenous plant species. Field studies were conducted to compare in situ root growth patterns of warm-season (WS) and cool-season (CS) perennial grasses and musk thistle during a 2-yr period that included a drought in the second year. In 2 yr, CS grasses had the highest amount of roots (1,296 m roots m^–2 [395 ft roots ft^–2]) across shallow (0 to 28 cm [0 to 11 in.]), medium (28 to 56 cm), and deep (56 to 98 cm) depths …

Phenotypic Variation In Native North American And Invasive Chinese Populations Of Plantago Virginica, Teresa E. Popp

College of Graduate Studies: Theses & Dissertations

Alien plant species can cause significant economic and biological destruction by invading new environments and outcompeting native species. Through experimental research, the mechanisms by which these species invade can be better understood and applied to their management. Plantago virginica is a perennial herb, native to North America that has recently invaded China. It has been known to reduce crop growth and harbor diseases in the introduced range. A common garden study was conducted at the Georgia Southern University greenhouse, comparing twenty populations of P. virginica from both the native North American and invasive Chinese ranges. I examined if there were …

Dual Capture Of A Piñon Deer Mouse And A Silky Pocket Mouse Resulting In Consumption Of The Smaller Animal, Jon C. Pigage, Roger D. Peyton

The Prairie Naturalist

Intraspecific dual captures of rodents are uncommon, but not rare. There are several reports of brown rats (Rattus norvegicus), white-footed deer mice (Peromyscus leucopus), North American deer mice (P. maniculatus), western harvest mice (Reithrodontomys megalotis) and meadow voles (Microtus pennsylvanicus) caught simultaneously in the same trap (i.e. a door-closing live-trap; Davis 1955, Getz 1961, Blaustein and Rothstein 1978, Jenkins and Llewellyn 1981, Novak 1983). Some reports are incidental whereas others are interpreted as social associations or bonding between conspecifics. Interspecific dual captures are rarely reported in the literature. The earliest report of …
