Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub- Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current levels of cereal consumption already depend on substantial imports. At issue is whether SSA can meet this vast increase in cereal demand without greater reliance on cereal imports or major expansion of agricultural area and associated biodiversity loss and greenhouse gas emissions. Recent studies indicate that the global increase …
Invasive Species In An Urban Flora: History And Current Status In Indianapolis, Indiana, Rebecca W. Dolan
Invasive Species In An Urban Flora: History And Current Status In Indianapolis, Indiana, Rebecca W. Dolan
Rebecca W. Dolan
Invasive plant species are widely appreciated to cause significant ecologic and economic damage in agricultural fields and in natural areas. The presence and impact of invasives in cities is less well documented. This paper characterizes invasive plants in Indianapolis, Indiana. Based on historical records and contemporary accounts, 69 of the 120 species on the official Indiana state list are reported for the city. Most of these plants are native to Asia or Eurasia, with escape from cultivation as the most common mode of introduction. Most have been in the flora of Indianapolis for some time. Eighty percent of Indianapolis’ invasive …
Can Functional Traits Predict Plant Community Response To Global Change?, Sarah Kimball, Jennifer L. Funk, Marko J. Spasojevic, Katharine N. Suding, Scot Parker, Michael K. Goulden
Can Functional Traits Predict Plant Community Response To Global Change?, Sarah Kimball, Jennifer L. Funk, Marko J. Spasojevic, Katharine N. Suding, Scot Parker, Michael K. Goulden
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
One primary goal at the intersection of community ecology and global change biology is to identify functional traits that are useful for predicting plant community response to global change. We used observations of community composition from a long-term field experiment in two adjacent plant communities (grassland and coastal sage shrub) to investigate how nine key plant functional traits were related to altered water and nitrogen availability following fire. We asked whether the functional responses of species found in more than one community type were context dependent and whether community-weighted mean and functional diversity were significantly altered by water and nitrogen …
Salvinia Molesta: An Assessment Of The Effects And Methods Of Eradication, Arti Lal
Salvinia Molesta: An Assessment Of The Effects And Methods Of Eradication, Arti Lal
Master's Projects and Capstones
Salvinia molesta is an invasive aquatic fern. It is now the second worse aquatic invader in the world. Since the 1930s, it has invaded most tropical and some temperate countries. S. molesta plants grow vegetatively and can increase in size rapidly. S. molesta can form thick mats of up to 1-meter-thick. There are a number of ways these thick mats negatively affect the environment: 1) reduce light to benthic organisms, 2) reduce oxygen in the water column for other organisms, 3) accumulate as organic matter at the bottom of the water column, 4) decrease nutrients for other organisms, and 5) …
Finding The Best Remaining Black Hills Montane Grasslands, The First Step In Conservation, Hollis Marriott, Don Faber-Langendoen, David J. Ode
Finding The Best Remaining Black Hills Montane Grasslands, The First Step In Conservation, Hollis Marriott, Don Faber-Langendoen, David J. Ode
The Prairie Naturalist
Black Hills Montane Grassland is a rare and endangered plant community endemic to the Black Hills of western South Dakota and northeastern Wyoming. It is restricted to higher elevations on the Limestone Plateau in the western part of the uplift. Early visitors to the Black Hills wrote glowing reports of flower-filled grasslands on the Limestone Plateau. Lieutenant Colonel George A. Custer and his soldiers reveled in lush grass, and decorated the headgear of their horses with flowers (Custer 1875). Expedition botanist A. B. Donaldson “estimated the number of flowers in bloom in Floral Valley at 50, while an equal number …
Review Of Estimation Of Parameters For Animal Populations: A Primer For The Rest Of Us By Larkin A. Powell And George A. Gale, Max Post Van Der Burg
Review Of Estimation Of Parameters For Animal Populations: A Primer For The Rest Of Us By Larkin A. Powell And George A. Gale, Max Post Van Der Burg
The Prairie Naturalist
“Me? A modeler? Never!” This is the opening challenge of the book, Estimation of Parameters for Animal Populations: A Primer for the Rest of Us, by Larkin Powell and George Gale. I say “challenge” because I think this book attempts to challenge the misconception that quantitative methods are out of reach for most biologists and wildlife scientists. When many of us attend college or graduate school to study wildlife science there’s a sense that, at some point, there will be math. But it appears that the attitude of many students toward this reality is to simply suffer through the …
Spatial Variation In Germination Of Two Annual Brome Species In The Northern Great Plains, Erin K. Espeland, Jane M. Mangold, Natalie M. West
Spatial Variation In Germination Of Two Annual Brome Species In The Northern Great Plains, Erin K. Espeland, Jane M. Mangold, Natalie M. West
The Prairie Naturalist
Downy brome or cheat grass (Bromus tectorum L.) and field brome (B. arvensis L.; Synonym = Bromus japonicus Thunb. ex Murr.; Japanese brome) are two annual exotic species that have increased the intensity and frequency of fire cycles in the Intermountain West of the United States, with millions of dollars in associated costs (DiTomaso 2000). These invasive brome species have a different impact in the Northern Great Plains of North America where they commonly co-occur in disturbed sites (White and Currie 1983, Haferkamp et al. 1993). In these mixed-grass prairie rangelands, annual bromes compete against other forage species …

Changes In The Prairie Naturalist For 2017: Some Bumps In The Road During Transition, Christopher N. Jacques
The Prairie Naturalist
By now it is obvious to most of our members and authors that The Prairie Naturalist (TPN) has experienced some delays in conducting journal-related business over the past few months. Publication of the June 2016 issue was slightly delayed and the December 2016 was mailed much later than planned. So I wanted to update our members on the current status, and other aspects, of TPN. As most of you know, when I transitioned into the Editorship of TPN, one of my first orders of business was to secure a new publication venue for the journal. Fortunately, the Department …
Review Of Waterfowl Of North America, Europe, And Asia: An Identification Guide By Sébastien Reeber, William L. Hohman
Review Of Waterfowl Of North America, Europe, And Asia: An Identification Guide By Sébastien Reeber, William L. Hohman
The Prairie Naturalist
Ducks, geese and swans (Family Anatidae) are the most popular and best studied group of birds in the world. The group has been the subject of classical books by Kortright (1942), Delacour (1954-1964), Bellrose (1976), Palmer (1976), Johnsgard (1978), and, most recently, Kear (2005) and Baldassarre (2014). The latest contribution to this rich legacy is an impressively illustrated identification guide for waterfowl found in North America, Europe and Asia by author and artist, Sébastien Reeber. This is an English-language version of Canards, Cygnes et Oies d’Europe, d’Asie et d’Amérique du Nord, published by Delachaux and Niestlé in late 2015. …
Review Of Plants Have So Much To Give Us, All We Have To Do Is Ask: Anishinaabe Botanical Teachings By Mary Siisip Geniusz (Edited By Wendy Makoons Geniusz, Illustrated By Annmarie Geniusz), Natasha Myhal, Kelly Kindscher
Review Of Plants Have So Much To Give Us, All We Have To Do Is Ask: Anishinaabe Botanical Teachings By Mary Siisip Geniusz (Edited By Wendy Makoons Geniusz, Illustrated By Annmarie Geniusz), Natasha Myhal, Kelly Kindscher
The Prairie Naturalist
Plants Have So Much to Give Us, All We Have to Do Is Ask offers a new look at Anishinaabe (Ojibwe) ethnobotany as told through traditional stories. Botanical teachings through stories are a way to pass down traditional knowledge from generation to generation. For example, Anishinaabe knowledge on plants was written and recorded in communities willing to share their knowledge with early scholars, such as Albert B. Reagan (1928), Huron H. Smith (1932), and Melvin R. Gilmore (1933). Each of these scholars spent time with an Anishinaabe community to learn about plants and primarily to provide written descriptions of plants …

Assessment Of Smallmouth Bass Growth And Mortality In Nebraska Waters, Benjamin J. Schall, Keith D. Koupal, Casey W. Schoenebeck, Keith L. Hurley
The Prairie Naturalist
Smallmouth bass (Micropterus dolomieu) have been introduced across Nebraska into a variety of waterbodies. However, an estimate of smallmouth bass growth and mortality in Nebraska waters has not been produced. The objectives of this study were to use historic sampling data to describe the growth of smallmouth bass in Nebraska lakes in relation to other regional models, growth among waterbody types (reservoirs, Interstate 80 [I-80] lakes, and rivers), estimates of age at quality, preferred, and memorable lengths, and mortality for Nebraska smallmouth bass populations. Mean length ± SE of Nebraska smallmouth bass at age 7 was 383 ± …
Review Of Booming From The Mists Of Nowhere: The Story Of The Greater Prairie-Chicken By Greg Hoch, Ross H. Hier
Review Of Booming From The Mists Of Nowhere: The Story Of The Greater Prairie-Chicken By Greg Hoch, Ross H. Hier
The Prairie Naturalist
The Greater Prairie-Chicken (Tympanuchus cupido pinnatus) is an iconic species inhabiting one of the most iconic and rarest habitats in the world—the tallgrass prairies of central North America. To tell the story of the Greater Prairie-Chicken is a monumental task. Its history is intricately woven into pre- and post-European settlement of the North American prairies in such a way that knowledge of the species is spread over several centuries. Thus, researching the “old and the new” regarding the Greater Prairie-Chicken requires a substantial literature review, much of which occurs in publications from the 1800s. Hoch has done a …

The Birds of Montana is an impressive-looking tome, that includes 659 pages, 155 color range maps, 73 illustrations of species, and 16 color photos of Montana’s habitats. Upon the first bend of the binding, the reader will quickly realize the impressive depth of detail and research that went into writing and completing this book. Although Montana is the fourth largest state, one of the least populated states, and has few “binoculars on the ground,” the state has a fascinating and extensive ornithological history. The Birds of Montana is not a field guide, but rather it is an astonishingly comprehensive reference …
Ultrastructural Changes During Pollen Wall Development And Germination In Arabidopsis Thalaiana, Katrina Olsen
Ultrastructural Changes During Pollen Wall Development And Germination In Arabidopsis Thalaiana, Katrina Olsen
Theses and Dissertations
The Arabidopsis thaliana meiotic mutant 6491 has been identified as displaying temperature sensitive male reduced- fertility. It has been determined that callose wall formation is defective, both in temporal and structural areas. There is irregular rippling in the plasma membrane and aberrant formation of the exine portion of the pollen wall. A developmental study using brightfield, epifluorescence, and transmission electron microscopy of the early stages of wall formation in 6491 has been completed, along with a similar study of Arabidopsis thaliana (L.) heynh, ecotype Wassilewskija (WS). Due to the temperature-sensitive nature of the mutant line, a further study of both …

Mechanism Of Resistance, Gene Flow, And Integrated Management Of Ragweeds (Ambrosia) In Nebraska, Zahoor Ahmad Ganie
Mechanism Of Resistance, Gene Flow, And Integrated Management Of Ragweeds (Ambrosia) In Nebraska, Zahoor Ahmad Ganie
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Common ragweed (Ambrosia artemisiifolia L.) and giant ragweed (Ambrosia trifida L.) are native annual broadleaf weeds in the United States found in diverse agroecosystems, roadsides, and wastelands. They are economically important weed species in the Midwest and sources of pollen allergies. Confirmation of glyphosate-resistant (GR) common and giant ragweed in Nebraska justified the need to determine the mechanism of resistance, dispersal of resistance genes via pollen, and to develop an integrated management program. The objectives of this research were to: 1) determine the mechanism of glyphosate resistance in a common ragweed biotype from Nebraska; 2) evaluate the effect …

Wetland Invasion By Typha×Glauca Increases Soil Methane Emissions, Beth A. Lawrence, Shane Lishawa, Nancy Tuchman, Nia Hurst, Buck T. Castillo
School of Environmental Sustainability: Faculty Publications and Other Works
Wetland invasion by monotypic dominant plants can alter the physicochemical and biological properties of soils that affect methane emissions, a potent greenhouse gas. We examined the effects of Typha × glauca invasion on soil methane using laboratory incubation and controlled mesocosm experiments. Typha-invaded soils collected from three Midwestern (USA) wetlands had greater methane production potential during laboratory incubation than soils dominated by native wet meadow vegetation. Ten years post-invasion of native plant-dominated mesocosms, Typha increased methane emissions at least three-fold (native: 15.0 ± 10.5 mg CH4-C m−2 h−1, median: 6.1 mg CH4-C …

For species with potential as new crops, rapid improvement may be facilitated by new genomic methods. Apios (Apios americana Medik.), once a staple food source of Native American Indians, produces protein-rich tubers, tolerates a wide range of soils, and symbiotically fixes nitrogen. We report the first high-quality de novo transcriptome assembly, an expression atlas, and a set of 58,154 SNP and 39,609 gene expression markers (GEMs) for characterization of a breeding collection. Both SNPs and GEMs identify six genotypic clusters in the collection. Transcripts mapped to the Phaseolus vulgaris genome–another phaseoloid legume with the same chromosome number–provide provisional genetic …

Studying The Effects Of Serpentine Soil On Adapted And Non-Adapted Species Using Arduino Technology, Kiana Saniee, Edward Himelblau, Brian Paavo
STAR Program Research Presentations
Abstract: Serpentine soils are formed from ultramafic rocks and are represent an extreme environment for plants. Serpentine soils are unique in that they carry high concentrations of heavy metals, are nutrient deficient, particularly in calcium, and have poor water retention capabilities. Although these soils constitute harsh conditions for plant growth, there are a number of species that are adapted and even endemic to serpentine soil. Water retention by commercial potting mix was compared with serpentine soil. Also, serpentine adapted and non-adapted species were grown in both soil treatments and physiological data were collected. We used the Arduino electronic platform to …

Impacts Of Fog Drip On Survivorship And Growth Of Native Herb And Shrub Seedlings On Santa Rosa Island, Julianne Bradbury, Ken Niessen, Kathryn Mceachern
Impacts Of Fog Drip On Survivorship And Growth Of Native Herb And Shrub Seedlings On Santa Rosa Island, Julianne Bradbury, Ken Niessen, Kathryn Mceachern
STAR Program Research Presentations
Overgrazing on Santa Rosa Island led to loss of topsoil in ridgeline groves of endemic island oaks (Quercus tomentella). Restoration specialists attempting to mitigate the impacts of wind and water erosion must determine efficient methods of reestablishing native vegetation. Planting pillows, burlap sacks filled with planting mix and attached to the bedrock substrate, may nurture seedlings long enough for their roots to penetrate the underlying sandstone. Since the island’s ridgeline habitat is often inaccessible during the rainy season, restoration efforts are largely confined to the dry summer months, during which condensed fog is an important source of moisture …

The Floral Charms Of Saint John’S: A Survey Of Botanical Communities, Stephen G. Saupe, Paul Melchior
The Floral Charms Of Saint John’S: A Survey Of Botanical Communities, Stephen G. Saupe, Paul Melchior
Headwaters
Saint John’s is a “landscape paradise” in central Minnesota. Although no complete checklist of vegetation exists for the campus, various surveys reveal a diverse flora. This floral wealth is the result of several terrestrial biomes converging on campus — prairie, savanna, deciduous forest, and coniferous forest — as well as diverse aquatic habitats including both lakes and wetlands. A 56-acre restored prairie at the entrance of Saint John’s is dominated by big bluestem and little bluestem. A savanna has been restored to the north and east of the Gemini Lakes and is characterized by bur oaks scattered among prairie grasses …
