Comparing Plant Diversity In Native Landscaping At Calvin University, Rine Wakeman, Dave Warners
Summer Research
Calvin University is home to several naturally planted sites, including woodland areas, three rain gardens, and several landscaping beds. The plants that populate these areas are native to Calvin’s watershed and West Michigan. Until this year, no database existed to keep track of which species of plants grow on campus and where. Over the summer, native sites on campus were surveyed to compile a database of the unique species found to examine the capacity for non-human, non-plant diversity on campus. How does the diversity of native sites compare to traditionally planted sites of similar size or position on Calvin University's …

A Vascular Flora Of The Selkirk Mountains, Bonner And Boundary Counties, Idaho, Harpo Faust, Ben Legler, David C. Tank
Aliso: A Journal of Systematic and Floristic Botany
The vascular flora described here covers ~2295 square kilometers (~886 square miles) of the Selkirk Mountains that lie in the Idaho Panhandle, covering an elevational range of 540–2330 m (1770–7670 ft). The majority of the mountain range is underlain by granitic rock of the Kaniksu Batholith, and is diversified by the rich glacial history of the Panhandle. The study area contains multiple pockets of alluvial and glacial deposition that serve as specialized habitat for present-day floristic diversity within the range. The Idaho Selkirks are part of the Northern Rocky Mountains and have floristic influences from the Pacific coast, boreal north, …

Department of Agronomy and Horticulture: Faculty Publications
The Pseudomonas syringae DC3000 type III effector HopAM1 suppresses plant immunity and contains a Toll/interleukin-1 receptor (TIR) domain homologous to immunity-related TIR domains of plant nucleotide-binding leucine-rich repeat receptors that hydrolyze nicotinamide adenine dinucleotide (NAD+) and activate immunity. In vitro and in vivo assays were conducted to determine if HopAM1 hydrolyzes NAD+ and if the activity is essential for HopAM1’s suppression of plant immunity and contribution to virulence. HPLC and LC-MS were utilized to analyze metabolites produced from NAD+ by HopAM1 in vitro and in both yeast and plants. Agrobacterium-mediated transient expression and in planta inoculation assays were performed to …

Preventative Weed Management Strategies In Arkansas Tomato Production, Gracie E. Morrison, Matthew Bertucci
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Cost-effective weed suppression is an important consideration for tomato growers. Growers often choose methods which minimize hand labor, as hand weeding can be prohibitively expensive. This project determined economic viability of high tunnel tomatoes treated with several methods of weed control, both organic and chemical. These methods included: 2-week hand weeding, 1-week hand weeding, preemergent herbicide application (plots sprayed with herbicide prior to weed emergence), straw mulch (plots bedded with straw), landscape fabric (plots covered in fabric), and untreated weedy control plots. These six treatments were applied to randomized blocks in a high tunnel. Weeding, planting, and harvesting were all …
Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz, Lisa S. Wood
Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz, Lisa S. Wood
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Food insecurity is a growing issue in developing and developed countries alike, and in countries like Belize, the prevalence of hunger has soared in recent years. Not having access to diets with sufficient calories and nutrients leads to a host of developmental issues, including stunting and cognitive delays. The purpose of this work was to create an all-encompassing manual for small-scale poultry production in order to provide nourishment for the students and staff of a school in Belize. After determining that the best way to meet the school’s needs was through dual-purpose birds, background research was conducted to determine small-scale …
Review Of Spiders Of North America, By Sarah Rose, Michael L. Draney
Review Of Spiders Of North America, By Sarah Rose, Michael L. Draney
The Prairie Naturalist
A field guide to spiders, the dominant terrestrial predator group, has long been a desire for North American naturalists, biologists, and spider fans, but not surprisingly, the first “real” field guide has been a long time coming. The diversity of spiders, with over 50,000 known species globally (World Spider Catalog 2022) and around 4,000 in North America north of Mexico (Rose 2022), is well beyond the diversity of more traditional field guide targets such as birds (about 1,000 species north of Mexico; American Birding Association 2022) or butterflies (about 725 species north of Mexico; North American Butterfly Association 2022). Also, …
Review Of Methods For Ecological Research On Terrestrial Small Mammals, By Robert Mccleery, Lynda R. Lafond
Review Of Methods For Ecological Research On Terrestrial Small Mammals, By Robert Mccleery, Lynda R. Lafond
The Prairie Naturalist
Small mammals are used in ecological studies throughout the world, yet the subject has lacked a clear reference that included upto- date methods pertaining to passive detection, molecular, and statistical approaches. In Methods for Ecological Research on Terrestrial Small Mammals, McCleery and his coauthors build on previous research references (Braun 2005, Sutherland 2006, Krebs 2014, Silvy 2020) and present methodologies specific to the study of small mammals that are applicable globally. Written as an asset for novice and experienced small mammal researchers alike, Methods for Ecological Research on Terrestrial Small Mammals is organized in a logical format, providing readers …

Second Twenty-Five Year Index: Volumes 26–50, 1994–2018, Jane E. Austin
The Prairie Naturalist
The first 50 years of the Prairie Naturalist reside on the shelves of libraries and personal collections. The articles and notes published over those years provide invaluable knowledge about Great Plains biota, communities, conservation, and landscape ecologies. Awareness of the wealth of information in those 50 print volumes has been limited, relying on references from other published papers or the limited number of articles that have been made available online by authors. This index serves as resource for individuals to digitally tap into the information published since 1994. This index, together with the first 25-year index, serves to complement the …

Wyoming’S Wild Horse Ranch: History And Description Of A Socio-Ecological Experiment, Alex Sas-Jaworsky, John Derek Scasta
Wyoming’S Wild Horse Ranch: History And Description Of A Socio-Ecological Experiment, Alex Sas-Jaworsky, John Derek Scasta
Human–Wildlife Interactions
The growing population of free-roaming horses (Equus ferus caballus) on western public rangelands has necessitated that federal agencies, such as the Bureau of Land Management (BLM) and U.S. Forest Service, develop novel approaches to curb growth including reproduction management. However, bureaucracy has hindered effective research and application of horse management on public lands and examples on private lands may present new solutions. Here we present the history and current population management strategy for the Wild Horse Ranch (WHR) located in southeastern Wyoming, USA, as an example of an ongoing private entity managing horses. Prior to 1985, this ~6,000-ha …
Predicting Munsell Color For Turfgrass Leaves, William L. Berndt, Roch E. Gaussoin
Predicting Munsell Color For Turfgrass Leaves, William L. Berndt, Roch E. Gaussoin
Department of Agronomy and Horticulture: Faculty Publications
Linking turfgrass color to hue, value, chroma (H V/C) in the Munsell Plant Tissue Color Book is a visual comparison process for specifying and communicating plant color. If subjectivity of visual comparison can be mitigated, then accuracy of color matching may be improved. Research was conducted to develop an algorithm predicting H V/C from CIE-xyY color (xyY) in digital images of leaves of four turfgrasses. First, value-chroma (V/C) arrays for Munsell hue groups 5Y, 2.5GY, 5GY, 7.5GY, 10GY, and 2.5G were converted to xyY. Next, chromaticity (xy) plots from each array were fitted with …

Forecasting The Outcomes Of Managing A Rare Endemic Plant At Its Elevational Limit Under Climate Change Scenarios, Ethan Reibsome
Forecasting The Outcomes Of Managing A Rare Endemic Plant At Its Elevational Limit Under Climate Change Scenarios, Ethan Reibsome
Cal Poly Humboldt theses and projects
Lupinus constancei (Lassics lupine) is an exceptionally rare forb with a population that in 2020 consisted of 1,300 individuals located on two adjacent mountaintops in northwestern California, USA. Past work has demonstrated the species is threatened by high levels of seed predation by small mammals, which is likely the result of fire exclusion and the subsequent vegetation encroachment that both increases small mammal habitat and directly reduces suitable habitat for the species. Because of this, active management through caging of reproductive individuals to reduce seed consumption has been conducted every year since 2003. In addition, growing season temperatures have increased …

A Question Of Priority: Pterospora Andromedea Nuttall Vs. Monotropa Procera Torrey Ex Eaton (Monotropoideae, Ericaceae), Gary D. Wallace
A Question Of Priority: Pterospora Andromedea Nuttall Vs. Monotropa Procera Torrey Ex Eaton (Monotropoideae, Ericaceae), Gary D. Wallace
Aliso: A Journal of Systematic and Floristic Botany
Clarity is lacking on the priority of the names Pterospora andromedea Nutt. versus Monotropa procera Torr. ex Eaton, both of which were published in 1818, and the suggested clear answer may not be the correct answer. Taxonomic Literature, second edition, provides a publication date of 14 July 1818 for Nuttall’s Genera of North American Plants and a publication date of June 1818 for Eaton’s Manual of Botany ed. 2. However, upon closer scrutiny, the situation is more complex. The sources for these publication dates are discussed in order to trace the likely sequence of events leading up …

Characterization Of Salt And Drought Tolerance In Sunflower (Helianthus Annuus L.), Sevgi Saylak
Characterization Of Salt And Drought Tolerance In Sunflower (Helianthus Annuus L.), Sevgi Saylak
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Consequent to the increasing world population, food sources are needed to be increased to meet the nutritional needs. However, due to natural processes and agricultural activities, the most destructive environmental factors that limit crop production, soil salinity, and drought-exposed areas are growing. As one of the major oilseed crops, sunflower (Helianthus annuus L.), is considered to be moderately tolerant to salt and drought. Although it can grow in arid to semi-arid regions, increasing salinity and drought might adversely affect sunflower production. This study aimed to investigate several sunflower germplasms' morphological responses to salt and drought stresses. For this purpose, …
