Healing Sanctuary, Kammy Downs
Healing Sanctuary, Kammy Downs
Master's Theses
The natural world has hidden wisdom and resources that are disregarded as we misuse our responsibility to care for them. The benefits of being in tune with nature have been traded for a culture that manipulates nature on the altar of expediency, waste, and unquenchable desire. Healing Sanctuary presents a duality. My work speaks about the relationship between the seen and unseen, represented by ten larger-than-life drawings of medicinal herbal plants that have had a profound physical healing effect on me. At the same time, plants, roots, and seeds create visceral metaphors for mental health. Our accomplishments, outlook on life, …
Evaluation Of Methods For The Restoration Of Native Grasslands On Abandoned Center Pivots In The Sandsage Prairies Of Southwestern Kansas, Alonso Barragan-Martinez
Evaluation Of Methods For The Restoration Of Native Grasslands On Abandoned Center Pivots In The Sandsage Prairies Of Southwestern Kansas, Alonso Barragan-Martinez
Master's Theses
Throughout southwestern Kansas thousands of acres of native grassland have been converted to cropland for agricultural use, reducing native prairie by over 60% in the sandsage prairie. Due to low precipitation and arid conditions, much of these croplands are irrigated by center pivot irrigation systems fed by the Ogallala Aquifer. These fields are abandoned when the aquifers dry up, resulting in erosion of the unused farmland. Conservation programs such as the Conservation Reserve Enhancement Program (CREP) were established to address this problem but have been unsuccessful in restoring native grasslands in abandoned croplands in southwestern Kansas. We hypothesized that insect …
The Influence Of Land Use On The Pollen Diet Of Honey Bee (Apis Mellifera) Colonies In Ellis County, Kansas, Ryan Engel
The Influence Of Land Use On The Pollen Diet Of Honey Bee (Apis Mellifera) Colonies In Ellis County, Kansas, Ryan Engel
Master's Theses
Pollinators are integral to plant ecology as well as to worldwide food availability and security. Understanding how human-driven land use change impacts the nutrition of managed honey bees is important in pollinator conservation efforts and can contribute towards combating recent pollinator declines. The objective of this study was to determine sources of forage for honey bees across different land use types in Ellis County, Kansas, through pollen analysis and taxonomic identification. Replicate study colonies were placed in three separate land use types: Urban, Cropland, or Native/Semi-native prairie. Pollen was sampled every 7 to 14 days throughout a growing season (April …
Influence Of Shaded Conditions On Development Of Asteraceae Species Native To Kansas, Aline Rodrigues De Queiroz
Influence Of Shaded Conditions On Development Of Asteraceae Species Native To Kansas, Aline Rodrigues De Queiroz
Master's Theses
to the heterogeneity of habitats, all plants are exposed to at least some degree of shade during their lifetime. Reduced light intensity, drops in R:FR ratio, and limited blue light are cues for plants to perceive competition; the shade avoidance syndrome (SAS) is common for grassland species while shade tolerance (ST) is common for forest species when competition is perceived. SAS is characterized by elongation of stems and petioles, reduced branches, decreased leaf area, decreased shoot biomass, and increased number of ramets. ST is characterized by little elongation of stems and petioles, high chlorophyll content and high chlorophyll a/b ratio …
Greening Rates And Photosynthetic Development Of Leaves In C3 And C4 Plants, Tayler J. Kriss
Greening Rates And Photosynthetic Development Of Leaves In C3 And C4 Plants, Tayler J. Kriss
Master's Theses
To study chlorophyll development time and overall photosynthetic development in C3 and C4 leaves, seeds were germinated in complete darkness and achlorophyllous leaves were then allowed to develop in lighted conditions. Corn (Zea mays, C4), sorghum (Sorghum bicolor, C4), green bean (Phaseolus vulgaris, C3), broad bean (Vicia faba, C3), and wheat (Triticum aestivum, C3) were investigated for the first ten days of sunlight exposure. Chlorophyll concentration, chlorophyll fluorescence, and CO2 gas exchange measurements were conducted daily on the first leaf that emerged after the embryonic leaves of each plant. The first five days of the experiment, days zero to four …
