The Significance Of Micro-Prairie Reconstruction In Urban Environments, Bruno Borsari, Neal Mundahl, Malcom F. Vidrine, Marc Pastorek

The Prairie Naturalist

An aggressive urban sprawl during the last half century has not only contributed to habitat disturbance and extirpation, as well as a loss of knowledge and appreciation for biodiversity. Across the United States, prairie reconstruction has been a very effective approach for developing sustainable landscape designs in city parks and other open spaces. The purpose of this work is to focus on restoration and reconstruction of selected micro-prairies as a vehicle for enhanced place-based education and to partially remediate the consequences of global climate change and loss of pollinators. From the coastal prairies of southwestern Louisiana, to the eastern edge …

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 …

Genetic Predictors Of Metabolic Side Effects Of Diuretic Therapy, Jorge L. Del Aguila

Dissertations and Theses (Open Access)

Thiazide diuretics are a recommended first-line monotherapy for hypertension (i.e.SBP>140 mmHg or DBP>90 mmHg). Even so, diuretics are associated with adverse metabolic side effects, such as hyperlipidemia, hyperglycemia and hypokalemia which increase the risk of developing type II diabetes. This thesis used three analytical strategies to identify and quantify genetic factors that contribute to the development of adverse metabolic effects due to thiazide diuretic treatment. I performed a genome-wide association study (GWAS) and meta-analysis of the change in fasting plasma glucose and triglycerides in response to HCTZ from two different clinical trials: the Pharmacogenomic Evaluation of Antihypertensive Responses …

A Quantitative Analysis Of Kalandars And Captive Bears In Pakistan, Thomas P. Rooney, Kendra C. Millam

Biological Sciences Faculty Publications

In 2013, the Bioresource Research Centre (Islamabad, Pakistan) conducted a comprehensive census of the remaining dancing and bear-baiting bears in Pakistan. This involved locating and counting the actual involved bears and bear keepers (kalandars), collecting detailed socio-economic data from the bear-keepers, and identifying attitudes and key drivers behind this livelihood. This report summarizes the findings from the census, reveals relationships in the data that are not immediately apparent, and identifies potential leverage points for ongoing campaign efforts.

White-Tailed Deer Are A Biotic Filter During Community Assembly, Reducing Species And Phylogenetic Diversity, Danielle R. Begley-Miller, Andrew L. Hipp, Bethany H. Brown, Marlene Hahn, Thomas P. Rooney

Biological Sciences Faculty Publications

Community assembly entails a filtering process, where species found in a local community are those that can pass through environmental (abiotic) and biotic filters and successfully compete. Previous research has demonstrated the ability of white-tailed deer (Odocoileus virginianus) to reduce species diversity and favour browse-tolerant plant communities. In this study, we expand on our previous work by investigating deer as a possible biotic filter altering local plant community assembly. We used replicated 23-year-old deer exclosures to experimentally assess the effects of deer on species diversity (H′), richness (SR), phylogenetic community structure and phylogenetic diversity in paired …

Nitrogen Deposition Contributes To Soil Acidification In Tropical Ecosystems, Xiankai Lu, Qinggong Mao, Frank S. Gilliam, Yiqi Luo, Jiangming Mo

Biological Sciences Faculty Research

Elevated anthropogenic nitrogen (N) deposition has greatly altered terrestrial ecosystem functioning, threatening ecosystem health via acidification and eutrophication in temperate and boreal forests across the northern hemisphere. However, response of forest soil acidification to N deposition has been less studied in humid tropics compared to other forest types. This study was designed to explore impacts of long-term N deposition on soil acidification processes in tropical forests. We have established a long-term N deposition experiment in an N-rich lowland tropical forest of Southern China since 2002 with N addition as NH₄NO₃ of 0, 50, 100 and 150 kg …

Increased 5-Hydroxymethylcytosine And Decreased 5-Methylcytosine Are Indicators Of Global Epigenetic Dysregulation In Diffuse Intrinsic Pontine Glioma, Sama Ahsan, Eric H. Raabe, Michael C.

Introduction

Diffuse intrinsic pontine glioma (DIPG) is a malignant pediatric brain tumor associated with dismal outcome. Recent high-throughput molecular studies have shown a high frequency of mutations in histone-encoding genes (H3F3A and HIST1B) and distinctive epigenetic alterations in these tumors. Epigenetic alterations described in DIPG include global DNA hypomethylation. In addition to the generally repressive methylcytosine DNA alteration, 5-hydroxymethylation of cytosine (5hmC) is recognized as an epigenetic mark associated with active chromatin. We hypothesized that in addition to alterations in DNA methylation, that there would be changes in 5hmC. To test this hypothesis, we performed immunohistochemical studies to …

A Systematic Revision Of North American Tolypella A. Braun (Charophyceae, Charophyta), William Perez

Dissertations, Theses, and Capstone Projects

Charophyta comprises the algal classes Mesostigmatophyceae, Chlorokybophyceae, Klebsormidiophyceae, Coleochaetophyceae and Zygnematophyceae and the land plants. However, the precise phylogenetic position of these algal classes with respect to land plants is unresolved as are the phylogenetic relationships among genera in Charophyceae (Characeae). Characeae contains two tribes with six genera: tribe Chareae (Chara, Lamprothamnium, Lychnothamnus and Nitellopsis) and tribe Nitelleae (Nitella and Tolypella). Tolypella was considered the third most species-rich genus but, in the most comprehensive taxonomic treatment of Characeae, 16 Tolypella species were consolidated into two species, T. nidifica and T. intricata in sections Rothia …

Comparative Phylogeography, Phylogenetics, And Population Genomics Of East African Montane Small Mammals, Terrence Constant Demos

Dissertations, Theses, and Capstone Projects

The Eastern Afromontane region of Africa is characterized by striking levels of endemism and species richness which rank it as a global biodiversity hotspot for diverse plants and animals including mammals, but has been poorly sampled and little studied to date. Using mtDNA and multi-locus nDNA sequence data, genome-wide RAD-Seq SNP data, and morphological data, I identify major cryptic biogeographic patterns within and between 11 co-distributed small mammal species/species groups across the Eastern Afromontane region. I focus on two endemic montane small mammal species complexes, Hylomyscus mice and Sylvisorex shrews, co-distributed across the Albertine Rift (AR) and Kenya Highlands (KH) …

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 …

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 …

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 …

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 …

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 …

Book Review: The Iowa Lakeside Laboratory: A Century Of Discovering The Nature Of Nature. Michael J. Lannoo., Bonnie S. Bowen

The Prairie Naturalist

Iowa Lakeside Laboratory (a.k.a. Lakeside Lab) is one of several biological field stations that were established in the early 1900s and that have active educational and research programs today. Michael Lannoo’s account of the history of Lakeside Lab was initiated at the centennial celebration of the lab in 2009. Lannoo’s own connection with Iowa Lakeside Laboratory began as a student at Iowa State University and continues today as a member of the Lakeside Lab summer faculty and as Associate Director of Academics and Research. In his book, Lannoo describes field stations, and Lakeside Lab in particular, as educational institutions that …

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 …

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 …

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 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 …

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 …

The Equitable Contributions Of Environment, Management And Restoration Status On Grassland Diversity And Composition, Raeann C. Powers

School of Biological Sciences: Dissertations, Theses, and Student Research

Plant composition is controlled by a combination of environmental, biotic, historical and management factors. Although there has been much focus on restoring grassland diversity, it is unclear which factors and/or interactions of factors are constraining diversity in grasslands and the relative influences of different factors. We measured soil fertility, soil texture, grazing intensity, fire frequency and plant cover in 694 plots, located within 33 remnant and restored fields in managed grasslands in the central Great Plains. Using univariate (general linear model) and multivariate (PERMANOVA) analyses, we identified significant factors and their relative contributions to plant richness, evenness, floristic quality index …

Body Size And Geographic Range Do Not Explain Long Term Variation In Fish Populations: A Bayesian Phylogenetic Approach To Testing Assembly Processes In Stream Fish Assemblages, Stephen J. Jacquemin, Jason C. Doll

Biological Sciences Faculty Publications

We combine evolutionary biology and community ecology to test whether two species traits, body size and geographic range, explain long term variation in local scale freshwater stream fish assemblages. Body size and geographic range are expected to influence several aspects of fish ecology, via relationships with niche breadth, dispersal, and abundance. These traits are expected to scale inversely with niche breadth or current abundance, and to scale directly with dispersal potential. However, their utility to explain long term temporal patterns in local scale abundance is not known. Comparative methods employing an existing molecular phylogeny were used to incorporate evolutionary relatedness …

High Hiv Incidence In The Postpartum Period Sustains Vertical Transmission In Settings With Generalized Epidemics: A Cohort Study In Southern Mozambique, Caroline De Schacht, Nedia Mabunda, Orlando C. Ferreira Jr., Nalia Ismael, Nurbai Calu, Iolanda Santos, Heather J. Hoffman, Catharina Alons, Laura Guay, Ilesh V. Jani

Genomics and Precision Medicine Faculty Publications

Introduction: Acute infection with HIV in the postpartum period results in a high risk of vertical transmission through breastfeeding. A study was done to determine the HIV incidence rate and associated risk factors among postpartum women in Southern Mozambique, where HIV prevalence among pregnant women is 21%.

Methods: A prospective cohort study was conducted in six rural health facilities in Gaza and Maputo provinces from March 2008 to July 2011. A total of 1221 women who were HIV-negative on testing at delivery or within two months postpartum were recruited and followed until 18 months postpartum. HIV testing, collection …

Host Specificity And Co-Speciation In Avian Haemosporidia In The Western Cape, South Africa, Sharon Okanga, Graeme S. Cumming, Philip A.R. Hockey, Lisa Nupen, Jeffrey L. Peters

Biological Sciences Faculty Publications

Host and pathogen ecology are often closely linked, with evolutionary processes often leading to the development of host specificity traits in some pathogens. Host specificity may range from ‘generalist’, where pathogens infect any available competent host; to ‘specialist’, where pathogens repeatedly infect specific host species or families. Avian malaria ecology in the region remains largely unexplored, despite the presence of vulnerable endemic avian species. We analysed the expression of host specificity in avian haemosporidia, by applying a previously developed host specificity index to lineages isolated from wetland passerines in the Western Cape, South Africa. Parasite lineages were isolated using PCR …
