Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer
Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer
Art Theses and Dissertations
To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …
A Study Of Red Snapper (Lutjanus Campechanus) Ecology In The Northern Gulf Of Mexico And The Effect Of Variable River Outflow Using Stable Isotope Analysis Of The Food Web And Eye Lenses, Caitlin C. Slife
Dissertations
In the Mississippi Bight and surrounding waters, river outflow impacts the basal resources of the Red Snapper food web, altering carbon sources and impacting prey and predator isotopes. In this study, the impact of riverine outflow on nutrients, particulate organic matter (POM), and physical water parameters on Red Snapper and their food web was analyzed using stable isotope and stomach content analysis over 5 years. The Mississippi, Pearl, Pascagoula, and Mobile rivers were included in the analysis of river impact. The Mississippi and Mobile rivers were found to significantly impact nutrients and POM in the region. River outflow was also …
Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber
Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber
Electronic Theses and Dissertations
Fires impact ecosystems globally and due to climate change, there are shifts in fire regimes that impact ecological communities which provide essential ecosystem services. Focusing on arthropods, fire can influence this ubiquitous animal group in various way. We performed a comprehensive meta-analysis evaluating how fires impact differing arthropod functional groups. We found that overall, fire negatively effects community level responses for most functional groups with herbivores as the only exception showing some positive effects of fire. We also studied mixed-severity fires that burned >20 years ago and compared floral visitor communities across fire severities. We implemented a pollinator exclusion experiment …
Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout
Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout
Electronic Theses and Dissertations
Land use activities have caused disturbances that affect the quality of freshwater ecosystems worldwide. How the influences of land use along an environmental gradient and the associated environmental variables that may influence stream diversity and function is unclear. We address these issues by studying biodiversity, abundance, and functional diversity of macroinvertebrates across different land types along a gradient in Colorado, USA. We also address how diversity may change along an elevation gradient by analyzing previously published macroinvertebrate research. We found evidence that land use and disturbance are stronger explanations of changes in macroinvertebrate communities, rather than elevation. Functional trait patterns …

Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico. More than two dozen authors—most with decades of experience—review the origins of riparian science in the western United States, document what is currently known about riparian ecosystems, and project future needs. Topics are widespread and include: interactions with fire, climate change, and declining …
Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Student Scholar Symposium Abstracts and Posters
One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …
Dispersal: A Multidisciplinary Investigation Of Plant Life, Alexandra E. Arzt
Dispersal: A Multidisciplinary Investigation Of Plant Life, Alexandra E. Arzt
Theses and Dissertations
Using plants as a basis for exploring the interstices between the human and nonhuman, this thesis investigates ideas of awareness, intelligence, deep time, animism, and the fluctuating human perception of the agency of Nature. It outlines environmental art practices since the 1950s involving vegetal life. In addition, the paper provides a critical analysis of plant perception of Jakob von Uexküll’s work and theories of vital materialism and “critical plant studies” while noting recent studies in plant neurobiology. In my work, plants become active participants via their movement, seeding, and smell. This study takes the form of imitation, purposeful symbiosis, anthropomorphism, …
Hitchhiking Bats On The Great Lakes Of North America, Saska E.H. Lohi
Hitchhiking Bats On The Great Lakes Of North America, Saska E.H. Lohi
Dissertations, Master's Theses and Master's Reports
Bats can act as potential vectors for various zoonotic diseases and other pathogens. Therefore their interactions with people should be examined to mitigate potential risks. Bats are small flying mammals and hide in small crevices during daylight hours, making them difficult to observe. Consequently, they have a capacity to “hitchhike” on ships to be dispersed over large distances.
This study focused on anthropogenic unintentional bat translocations, i.e. hitchhiking bats. The study area is the Great Lakes region in North America. Using a web-based questionnaire survey, I asked the public about the frequency of bat-human encounters on ships, their nature, and …
Greater Sage-Grouse Habitat Selection And Use Patterns In Response To Vegetation Management Practices In Northwestern Utah, Stephanie E. Graham
Greater Sage-Grouse Habitat Selection And Use Patterns In Response To Vegetation Management Practices In Northwestern Utah, Stephanie E. Graham
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Greater sage-grouse (Centrocercus urophasianus; sage-grouse) are a sagebrush obligate species and an indicator of sagebrush (Artemisia spp.) habitat quality. Sage-grouse populations have declined across western North America. Fragmentation of landscapes and habitat loss have been identified as factors that negatively impact sage-grouse populations. Wildfires can increase the distribution of invasive plants and contribute to fragmentation and habitat loss across sagebrush ecosystems. Greenstripping has been identified as a technique to reduce the threat of wildfire and subsequent spread of invasive species. Forage kochia (Bassia prostrata) is a semi-shrub that contains a high moisture content year-round, high …

Quality and quantity of publications are among the most important measures determining the success of ecologists. The past 50 years have seen a steady rise in the number of researchers and collaborative manuscripts, and a corresponding increase in multi-authored articles. Despite these increases, there remains a shortage of useful and definitive guidelines to aid ecologists in addressing authorship issues, leading to a lack of consistency in what the term “author” really means. Deciding where to draw the line between those who have earned authorship and those who are more appropriately credited in the acknowledgments may be one of the more …

The purpose of this study was to provide basic ecological information on an important but little studied major vegetation type through autecological investigations of the dominant species. Data include climate and soils where this species occurs, root distribution, phenology and growth, seed germination requirements and seedling survival. Percent ground cover provided by blackbrush and other dominant plants as well as the composition of herbaceous understory vegetation was presented. Leaf and stem anatomy of blackbrush revealed features typical of desert shrub species with stem splitting appearing to be a characteristic of this species.
Blackbrush is characterized as a poor forage species …
Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller
Studies In The Life History And Ecology Of The American Pintail (Anas Acuta Tzitzihoa Vieliot) In Utah, Robert W. Fuller
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Wildlife management has been defined as lithe manipulation of wild populations of vertebrate animals in their relation to man and his interests" Wildlife management, then, could not exist in the absence ot either wildlife or humans. Converting this idea to the waterfowl situation, we can say that there are no waterfowl problems other than as they exist in the minds of men. (Wil1s, 1951) These words by the Chief of the IllinoIs Natural History Survey precede a plea for fundamental facts and a basic understanding of waterfowl upon which sound management can in turn be based. l"or only through sound …
A Taxonomic And Ecological Study Of Acridinae Of Utah (Orthoptera-Locustidae), Herald C. Bennion
A Taxonomic And Ecological Study Of Acridinae Of Utah (Orthoptera-Locustidae), Herald C. Bennion
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Orthoptera, especially the family Locustidae, is one of the most important and most interesting orders of insects in the state of Utah. It includes a polyphagus group of great economic importance in the state. The topography and climate of Utah varies from forested alpine slopes to hot arid desert wastes, several life zones being represented. This great variation from desert to alpine in Utah presents a rather unique region for taxonomic and ecological studies of the Orthoptera.
The most familiar representatives of the insect order Orthoptera are the long-horned grasshoppers, locusts, crickets, katydids, and cockroaches. Orthoptera are characterized by Comstock …
