Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia
Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia
Journal of Nonprofit Innovation
Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Testing The Potential Of Novel Grain Crop Cultivation In Rural Malawi During The Dry Season Through Irrigation And Soil Modification, Jessica Truman
Testing The Potential Of Novel Grain Crop Cultivation In Rural Malawi During The Dry Season Through Irrigation And Soil Modification, Jessica Truman
Undergraduate Honors Theses
This research project studied the germination and growth rates of oat and quinoa crops in Mtalimanja, Malawi. This project was part of a larger effort by General Mills and Brigham Young University researchers to increase the diversity and nutrient content of crops in impoverished countries worldwide. It was conducted from May to August 2017 during Malawi’s dry season. Tetraploid oats and quinoa, both modified to increase the protein content of harvested grains, were planted under three different soil conditions: unamended soil, soil mixed with composted chicken litter, and soil with surface-applied granular fertilizer. The research plots were watered daily except …

Influential Herbal And Botanical Texts From The 16th Through 18th Centuries, Michael C. Goates
Influential Herbal And Botanical Texts From The 16th Through 18th Centuries, Michael C. Goates
Faculty Publications
Humans have always had an intimate and complex relationship with plants. Plants provide many of the basic necessities for survival, such as food, clothing, and shelter. Plants also play an important and rich part in human culture. This fascination with plants has led to detailed studies of their natural history as well as explorations into their unique and useful properties. Throughout recorded history, philosophers, herbalists, botanists, and others have captured their observations about plants. From the Middle Ages through the Early Modern Period, herbalists compiled these collective observations into large printed volumes, referred to as herbals. With the Scientific Revolution …
Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen
Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen
Western North American Naturalist
In the northern U.S. Rockies, including the Greater Yellowstone Ecosystem (GYE), connectivity is a concern because large carnivores have difficulties dispersing successfully between protected areas. One area of high conservation value because of its importance for connecting the GYE to wilderness areas of central Idaho is the Centennial Mountains and surrounding valleys (2500 km2) along the Idaho–Montana border just west of Yellowstone National Park. The current expansion of grizzly bears (Ursus arctos) and other large carnivore populations outside protected areas of Yellowstone National Park and Grand Teton National Park has placed a greater emphasis on potential linkage zones …

Botanists In The Canyonlands Of The Colorado Plateau – 1950–1983 & Prior, Stanley L. Welsh, Glen Moore
Books by Faculty of the Monte L. Bean Life Science Museum
Abstract
This paper provides an overview of botanical investigations in southeastern Utah, but is not so-restricted geographically. It grew out of the discovery of decades-old manuscripts on the flora of what became Canyonlands National Park in 1964, but from those typescript copies the coverage grew outward geographically and backward in time to the earliest inhabitants of what is today known as the Four Corners Region of the American Southwest. Reviewed is the account of utilization of the region and its natural resources by aboriginal inhabitants who were familiar with all of it. That early, and to an extent, continuous occupation …

Botanist In Death Valley, Stanley L. Welsh
Books by Faculty of the Monte L. Bean Life Science Museum
Abstract
This book details the author’s trips to Death Valley, along with general ecological information about the region. Explorations by other natural historians are also recounted. Death Valley and its surrounding mountain ranges are stark and appear to lack vegetative cover, but that appearance is deceiving. The ranges and valley support a great diversity of living things, both plants and animals. Pages 10–17 contain photographs of various landscapes. Pages 18–20 list the plant species collected in Death Valley, 1970–1983. Voucher specimens are available for study at Stanley L. Welsh Herbarium, Brigham Young University.

Journals Of Travels, Stanley L. Welsh
Books by Faculty of the Monte L. Bean Life Science Museum
Abstract
It is unfortunate that journals were not kept routinely for all of my [Stanley L. Welsh] expeditions that resulted in collections of plants that formed the bases for publications over the years. Only the record books and the specimens document most of the trips, and they are without detail of the events leading up to them or of those that transpired on them. The journals reproduced here show good intentions, which unfortunately were not fulfilled subsequently. The early field trips from Iowa State, accompanied by Dennis Anderson set the tone for later trips to Alaska, in 1965, 1966, 1968, …
Water In Beaver Dam Wash And Lytle Preserve, Stanley L. Welsh
Water In Beaver Dam Wash And Lytle Preserve, Stanley L. Welsh
Books by Faculty of the Monte L. Bean Life Science Museum
This short work is derived from a manuscript prepared for presentation in a water adjudication hearing, following a proposal to pipe water from wells in Beaver Dam Wash for transfer across state lines to be used for culinary and other purposes in Mesquite, Nevada. The Wash is estimated to yield 2000 acre feet of water annually, mostly as subsurface flow, at the Arizona line. About a third of that amount is already appropriated by users along the Wash in Utah, but there are applications pending for more than 100,000 acre feet in Utah. Thus, the Wash is already oversubscribed by …

Bird Use Of Riparian Vegetation Along The Truckee River, Califonia And Nevada, Suellen Lynn, Michael L. Morrison, Amy J. Kuenzi, Jennifer C. C. Neale, Benjamin N. Sacks, Robin Hamlin, Linnea S. Hall
Great Basin Naturalist
The Truckee River in California and Nevada is subject to diverse water regimes and a corresponding variety of flow rates. Original riparian vegetation has been altered by these variable flow rates and by a variety of human uses resulting in loss of native riparian vegetation from its historic extent. We conducted bird surveys along the Truckee River during spring 1993 to (1) determine relationships between birds and the present vegetation; (2) determine the importance of different vegetation types to sensitive bird species that have declined recently in the western United States due to competition from exotic plant species, cowbird ( …

Winter Macroinvertebrate Communities In Two Montane Wyoming Streams, Christopher M. Pennuto, Frank Denoyelles Jr., Mark A. Conrad, Frank A. Vertucci, Sharon L. Dewey
Great Basin Naturalist
Macroinvertebrate communities were examined on 4 winter dates over a 4-yr period in 2 high-altitude Rocky Mountain streams to document overwintering assemblages potentially experiencing spring acid pulses. Taxa richness values were comparable to other published lists for alpine and montane stream systems despite the fact that most literature reflected summer collections. Mean benthic density ranged from 1406 to 19,734 organisms/m2, and drift rates ranged from 0 to 1740 organisms/100 m3. Benthic collections showed higher taxa richness than drift collections while the Ephemeroptera and Plecoptera occurred in greater proportions in drift than in benthos. The Nemouridae (Plecoptera), …

Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel
Great Basin Naturalist
Species of Artemisia (subgenus Tridentatae) dominate much of western North America. The genetic variation that allows this broad ecological adaptation is facilitated by hybridization and polyploidization. Three separate studies were performed in this group using randomly amplified polymorphic DNA (RAPD). Fifty-seven 10-mer primers generated nearly 400 markers from genomic DNA obtained from leaf tissue. These studies were (1) a measure of the variability of plants within and between populations and between subspecies using 5 A. tridentata ssp. wyomingensis populations, 2 A. cana ssp. cana populations, and 1 A. cana ssp. viscidula population; (2) an examination of the hypothesis that …

Helminths Of The Southwestern Toad, Bufo Microscaphus, Woodhouse's Toad, Bufo Woodhousii (Bufonidae), And Their Hybrids From Central Arizona, Stephen R. Goldberg, Charles R. Bursey, Keith B. Malmos, Brian K. Sullivan, Hay Cheam
Great Basin Naturalist
The gastrointestinal tracts, lungs, and urinary bladders from 77 Bufo microscaphus, 61 Bufo woodhousii, and 8 of their hybrids were examined for helminths. One species of trematode (Glypthelmins quieta), 1 species of cestode (Distoichometra bufonis), and 5 species of nematodes (Aplectana incerta, A. itzocanensis, Rhabdias americanus, Physaloptera sp., and Physocephalus sp.) were found. The greatest prevalence (41%) and mean intensity (231.7) were recorded for Aplectana incerta in Bufo woodhousii. It appears hybrids harbor fewer parasites than either parent species.

Effects Of Douglas-Fir Foliage Age Class On Western Spruce Budworm Oviposition Choice And Larval Performance, Kimberly A. Dodds, Karen M. Clancy, Kathryn J. Leyva, David Greenberg, Peter W. Price
Great Basin Naturalist
The western spruce budworm (Choristoneura occidentalis Freeman) prefers to feed on flushing buds and current-year needles of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco). Budworm larvae will not typically consume older age classes of needles unless all current-year foliage is depleted. We tested the following null hypotheses: (1) budworm larvae can feed on foliage with a wide range of qualities (i.e., current 1-, 2-, or 3-year-old needles) without measurable effects on fitness; and (2) budworm adults do not show any oviposition preference linked to the age of the foliage they fed on as larvae. We used both laboratory and field …

Selecting Wilderness Areas To Conserve Utah's Biological Diversity, Diane W. Davidson, William D. Newmark, Jack W. Sites Jr., Dennis K. Shiozawa, Eric A. Rickart, Kimball T. Harper, Robert B. Keiter
Great Basin Naturalist
Congress is currently evaluating the wilderness status of Bureau of Land Management (BLM) public lands in Utah. Wilderness areas play many important roles, and one critical role is the conservation of biological diversity. We propose that objectives for conserving biodiversity on BLM lands in Utah be to (1) ensure the long-term population viability of native animal and plant species, (2) maintain the critical ecological and evolutionary processes upon which these species depend, and (3) preserve the full range of communities, successional stages, and environmental gradients. To achieve these objectives, wilderness areas should be selected so as to protect large, contiguous …

On The Relative Importance Of Floral Color, Shape, And Nectar Rewards In Attracting Pollinators To Mimulus, Steven D. Sutherland, Robert K. Vickery Jr.
Great Basin Naturalist
Pollinator preferences were observed for the six species of section Erythranthe of the genus Mimulus using greenhouse-grown plants placed in a meadow in the Red Butte Canyon Natural Area, Salt Lake County, Utah. The principal pollinators were hummingbirds and bumble bees. Hummingbirds preferred the species with the most reflexed tubular flowers regardless of color, whereas bumblebees preferred pink. lavender, or yellow flowers to red flowers regardless of shape. Results for the six species were confirmed by observations of F2 hybrid recombinant plants selected such that flower color could be held constant and flower shape varied and vice versa.
