An Interview With Luce Irigaray On Through Vegetal Being: Two Philosophical Perspectives And Sexuate Difference, Andrea S. Wheeler Dec 2017

An Interview With Luce Irigaray On Through Vegetal Being: Two Philosophical Perspectives And Sexuate Difference, Andrea S. Wheeler

Architecture Publications

In this interview the philosopher Luce Irigaray discusses her book Through Vegetal Being. In response to questions, she distinguishes the human relationship to the environment and to other human beings. She describes how we must change our manner of relating to nature, beginning with our own: to learning how to coexist as a natural being among others instead of dominating the natural world. We must cultivate our instincts, free ourselves from traditions and elaborate a new education and sociocultural order and it is then that we will perceive that we cannot share with plants and animals all that we can ...


Urban Bobcat (Lynx Rufus) Ecology In The Dallas-Fort Worth, Texas Metroplex, Julie M. Golla Dec 2017

Urban Bobcat (Lynx Rufus) Ecology In The Dallas-Fort Worth, Texas Metroplex, Julie M. Golla

All Graduate Theses and Dissertations

Urban landscapes are quickly replacing native habitat around the world. As wildlife and people increasingly overlap in their shared space and resources, so does the potential for human-wildlife conflict, especially with predators. Bobcats (Lynx rufus) are a top predator in several urban areas across the United States and a potential contributor to human-carnivore conflicts. This study evaluated the movements and habitat use of bobcats in the Dallas-Fort Worth (DFW), Texas metroplex. Spatial data were collected from 10 bobcats via Global Positioning Satellite (GPS) for approximately one year. Average home range size was 4.60 km2 (n=9, SE=0 ...

The aims of the original proposed project remain the same, that is, to test the hypothesis that Managed Aquifer Recharge (MAR) for stormwater harvesting is a technically feasible, socially and environmentally acceptable, economically viable, and legally feasible option for developing new water supplies for arid Western urban ecosystems experiencing increasing population, and climate change pressures on existing water resources. The project is being carried out via three distinct but integrated components that include: 1) Monitoring of existing distributed MAR harvesting schemes involving a growing number of demonstration Green Infrastructure (GI) test sites; 2) Integrated stormwater/vadose zone/groundwater/ ecosystem services ...


Investigation Of Seed And Seedling Predation And Natural History Of Bushveld Savanna Rodents, Christopher Banotai Oct 2017

Investigation Of Seed And Seedling Predation And Natural History Of Bushveld Savanna Rodents, Christopher Banotai

Masters Theses & Specialist Projects

There is currently a decline in large, old trees within many ecosystems where they play important ecological and economic roles. One ecosystem suffering from this decline is the bushveld savanna of South Africa. One particularly important species in decline is the ecologically, economically, and culturally significant marula tree (Sclerocarya birrea subsp. caffra). This species’ decline is characterized by a steep drop in recruitment of seedlings into the population. Rodents are known to influence plant communities across many ecosystems through herbivory of adult plants as well as predation of seeds and seedlings. This research provides a record of rodent species present ...


Desert Pool {If Every Desert Was Once A Sea}, Karen Miranda Abel Sep 2017

Desert Pool {If Every Desert Was Once A Sea}, Karen Miranda Abel

The Goose

Desert Pool {If every desert was once a sea} is a site-specific art project by Canadian artist Karen Miranda Abel completed in 2016 while artist-in-residence at Joya: arte + ecología, an arts-led research centre situated in an alpine desert within a national park in southern Spain. The elemental installation represents an envisioning of the ancient sea that occupied the Sierra de María-Los Vélez Natural Park millions of years before the current desert ecology, a time when its highest mountain peaks may have been islands.


Ecology Of The Young-Of-The-Year Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River, New York: Growth, Diversity, And Importance As A Forage Species, Jacob L. Cochran Aug 2017

Ecology Of The Young-Of-The-Year Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River, New York: Growth, Diversity, And Importance As A Forage Species, Jacob L. Cochran

Great Lakes Center Masters Theses

The emerald shiner (Notropis atherinoides) is a relatively understudied Cyprinid that fills a major keystone role in the Niagara River. Little is known about the emerald shiner’s early life history, such as the ecology of their larval and juvenile stages, which is the focus of this study. In the upper Niagara River, larvae first recruited into sampling gear in early July at a mean water temperature of 23oC, with larvae appearing into August. Young-of-the-year (YOY) emerald shiners grew an average of 1.5 mm and 31.5 mg a week throughout the growing season with condition peaking ...


A Multi-Indicator Assessment Of Conservation Success Across A Populated Forest Anthrome, Emma Cook, Natalie Ribble, John Quinn Aug 2017

A Multi-Indicator Assessment Of Conservation Success Across A Populated Forest Anthrome, Emma Cook, Natalie Ribble, John Quinn

Biology Presentations

The heterogeneous landscape of the eastern United States has resulted in a diversity of conservation interventions including public protected areas, private lands held in easements, and open space managed at various levels of intensity. Given the pressures of expected land use and land cover change, particularly in the Southern Piedmont ecoregion, multi-scale and comprehensive data are needed to prioritize conservation actions. We assessed local and regional indicators of conservation success across an urban-rural gradient by analyzing local bird abundance and diversity as a factor of forest patch area, land use matrix, and land management strategy. The study was conducted across ...


A Hemimysis Driven Novel Ecosystem At A Modified Boulder Breakwall, Eric John Geisthardt Aug 2017

A Hemimysis Driven Novel Ecosystem At A Modified Boulder Breakwall, Eric John Geisthardt

Theses and Dissertations

The US Army Corps of Engineers (USACE) is mandated to maintain and repair aging breakwall structures in all commercial ports on the Great Lakes. In May of 2014, the construction of Milwaukee Harbor USACE “green” breakwall (GBW) reconciliation created complex rocky aquatic habitat by depositing cobble-sized stone as a veneer over standard 6-10 ton boulders, thus creating “control” (boulder) and “treatment” (cobble) habitats. The breakwall is home to a prolific population of Hemimysis anomala, the introduced Ponto-Caspian mysid, which is significantly more abundant on cobble versus boulders (p<0.05, using a novel trap for Hemimysis). Fish and forage communities were sampled in 2015 and 2016 using a combination of experimental and micromesh gill nets, night scuba diving surveys, and a novel Hemimysis trap. This nearshore lithophilic mysid appears to provide a significant new seasonal food resource in the Milwaukee Harbor for pelagic prey fishes during inshore spawning migrations and upwelling events. Alewife (Alosa pseudoharengus) and rainbow smelt (Osmerus mordax) fed heavily on Hemimysis with some individuals consuming hundreds of mysids. Night scuba diving surveys and gill netting confirmed that rainbow smelt preferred to forage on the cobble section (p<0.05), and also consumed more Hemimysis there than they did at the control breakwall site (p<0.05). Hemimysis were also the primary food item consumed by nearshore game fishes such as YOY yellow perch (Perca flavescens), YOY largemouth bass (Micropterus salmoides), and juvenile rock bass (Ambloplites rupestris) caught at the breakwall. This study provides the first documented evidence that where abundant in the Laurentian Great Lakes, Hemimysis do have the ability to significantly impact local food webs and drive the feeding ecology of both pelagic transient and nearshore resident fishes.


Microbial Community Richness Distinguishes Shark Species Microbiomes In South Florida, Rachael Cassandra Karns Jul 2017

Microbial Community Richness Distinguishes Shark Species Microbiomes In South Florida, Rachael Cassandra Karns

HCNSO Student Theses and Dissertations

The microbiome (microbial community) of individuals is crucial when characterizing and understanding processes that are required for organism function and survival. Microbial organisms, which make up an individual’s microbiome, can be linked to disease or function of the host organism. In humans, individuals differ substantially in their microbiome compositions in various areas of the body. The cause of much of the composition diversity is yet unexplained, however, it is speculated that habitat, diet, and early exposure to microbes could be altering the microbiomes of individuals (Human Microbiome Project Consortium, 2012b, 2012a). To date, only one study has reported on ...


Evaluating Zoysiagrass-Tall Fescue Mixtures In Kansas, Mingying Xiang, J. Fry, M. Kennelly Jul 2017

Evaluating Zoysiagrass-Tall Fescue Mixtures In Kansas, Mingying Xiang, J. Fry, M. Kennelly

Kansas Agricultural Experiment Station Research Reports

Water conservation is increasingly important when selecting turfgrasses. Zoysiagrass (Zoysia japonica), a C4 grass, is more drought resistant than C3 grasses. However, there is some resistance to the use of zoysiagrass in lawns and golf courses due to its extended dormant period when turf is brown. The objective of this study was to evaluate mowing height, tall fescue seeding rate and time for establishment of a mixed stand with seeded zoysiagrass. Seeding zoysiagrass and tall fescue together in June generally resulted in a less uniform mixture than seeding zoysiagrass in June and then seeding tall fescue in September. Tall fescue ...


Ecofeminism: The Path Towards Healing The Earth, Jamie Thompson Jun 2017

Ecofeminism: The Path Towards Healing The Earth, Jamie Thompson

Dialogue & Nexus

The concept of the patriarchy, or any concept in which one group dominates another, is inseparable from the formation of human kind’s domination of nature. This domination of nature has led to the current the ecological crisis humanity faces. Those who deny climate change can admit to the massive amounts of pollution, trash, and deforestation. Despite this worsening economic crisis, those in power have been slow to react. Women can ultimately provide and lead the movement to solve this ecological crisis through the growing movement of Ecofeminism. In the philosophy of Ecofeminism, individuals recognize and reject western dualistic thinking ...

The Off Season: Masculinities, Rurality, And Family Ties In Alaska Commercial Fishing, Cruz Morey May 2017

The Off Season: Masculinities, Rurality, And Family Ties In Alaska Commercial Fishing, Cruz Morey

Senior Theses

This study explores the intersections of masculinity, rurality, the family, and ecology through the experiences of commercial fishermen in Alaska. By understanding the plurality of masculinities and how men operate within a rural space, this study investigates the relationship between the masculine rural and the rural masculine and how that relationship pertains to commercial fishermen. This study examines existing discourse about Alaska and the masculinity of commercial fishermen in light of the concepts of cultural and economic capital, as well as local ecological knowledge (LEK). It further examines how fishermen describe their experiences in the industry as ones that are ...

Understanding The Complex Relationships Between Climate, Vegetation, And Foraging Behavior Of A Climate-Sensitive Alpine Mammal In Order To Explain Patterns Of Persistence, Evan Cole May 2017

Understanding The Complex Relationships Between Climate, Vegetation, And Foraging Behavior Of A Climate-Sensitive Alpine Mammal In Order To Explain Patterns Of Persistence, Evan Cole

Master's Projects and Capstones

Mountain ecosystems offer substantial ecosystem services but are highly sensitive to climate change. The American pika (Ochotona princeps) serves as an indicator species of climate change and a model organism for studying its impacts on mountain mammals. Certain aspects of plant community composition and structure can function as predictors of pika distribution, but understanding the links between climate, forage quality, and foraging behavior is necessary to identify the mediating mechanism. Pika foraging pressure help shape the local plant community, which can confound modeling efforts and must be considered when evaluating the influence of vegetation on pika persistence. Plant Secondary Metabolites ...

The Effects Of Urbanization On Nitrogen Processing In Urban Streams, Peter Francissen, Dr. Kevin Geedey, Dr. Michael Reisner May 2017

The Effects Of Urbanization On Nitrogen Processing In Urban Streams, Peter Francissen, Dr. Kevin Geedey, Dr. Michael Reisner

Celebration of Learning

Urban stream syndrome is described as the deterioration of stream health in an urbanized watershed and is associated with the loss of ecosystem services, which in turn degrades downstream environments. One key symptom of the urban stream syndrome is reduced processing of inorganic nitrogen. Previous research suggests that as urbanization increases and water quality decreases, the uptake length (Sw) of inorganic N increases. This indicates that the stream is increasing the export of N downstream compared to in situ incorporation of N into the ecosystem. We measured uptake length (Sw) of NO3, using a pulse addition method, along 9 different ...


Life History Of The Non-Native Invasive Red Lionfish (Pterois Volitans) In The Northern Gulf Of Mexico, Alexander Q. Fogg May 2017

Life History Of The Non-Native Invasive Red Lionfish (Pterois Volitans) In The Northern Gulf Of Mexico, Alexander Q. Fogg

Master's Theses

Invasive Red Lionfish (Pterois volitans) were first detected in the northern Gulf of Mexico (nGOM) in 2010 and since then their numbers have increased dramatically. From 2010 to 2015, more than 15,000 Red Lionfish were collected opportunistically from the nGOM for this study. Length and weight relationships differed significantly among ecoregions by sex and there was clear sexual dimorphism in size with males being larger and heavier. Red Lionfish age ranged from 0-4.5 years old and males achieved greater growth rate (K) and asymptotic maximum lengths (Linf) compared to females and these parameters were also different by ...


Effects Of Temperature Gradient, Substrate Composition, And Canopy Cover On The Spatial Distribution Of Topminnow Species: Fundulus Notatus And Fundulus Olivaceus, Austin M. King May 2017

Effects Of Temperature Gradient, Substrate Composition, And Canopy Cover On The Spatial Distribution Of Topminnow Species: Fundulus Notatus And Fundulus Olivaceus, Austin M. King

Honors Theses

Hybrid zones are locations where two interbreeding species coexist and hybridize. The spatial distribution of ecologically similar species is of primary interest in understanding the formation and stability of hybrid zones. These hybrid zones are of significance as they allow for insight into how speciation occurs naturally within the environment. A variety of factors may play a role in determining the spatial distributions of species within hybrid zones. Examples of these factors include variations in temperature gradients, substrate composition, and changes in canopy cover. Fundulus olivaceus and Fundulus notatus are generally found within upstream and downstream habitats respectfully. These habitats ...


Perception Of The Horizon Predicts Bird Abundance Better Than Habitat Patch Size In A Tidal Marsh Species Of Conservation Concern, Hallie Marshall May 2017

Perception Of The Horizon Predicts Bird Abundance Better Than Habitat Patch Size In A Tidal Marsh Species Of Conservation Concern, Hallie Marshall

Honors College

The Saltmarsh Sparrow (Ammodramus caudacutus) is a tidal marsh bird species facing rapid population decline throughout its range. A major cause of this decline is degradation and loss of breeding habitat, and thus there is a need to preserve coastal marshes in the northeastern United States. To do so requires an understanding of the habitat features that support robust populations. Previous studies have shown increases in Saltmarsh Sparrow abundance with marsh size increases. In other grassland bird species, habitat patches with low horizons are preferred to those with tall objects (e.g., trees, telephone poles, wind turbines). This study tests ...

Plasticity And Biotic Interactions Mediate Plant Persistence In A Changing World, Alix Ann Pfennigwerth May 2017

Plasticity And Biotic Interactions Mediate Plant Persistence In A Changing World, Alix Ann Pfennigwerth

Masters Theses

Anthropogenic global change is occurring today at a faster rate and larger scale than ever before. Understanding how plants will respond to such large-scale disturbance is critical for biodiversity conservation, yet the ecological and evolutionary mechanisms underlying these responses remain poorly understood. In this thesis, I investigated the mechanisms underlying plant response to two major drivers of global change, climate change and the widespread mortality of foundation species. First, I examined genetic and plastic plant trait responses to climatic variation using elevation gradients, which serve as space-for-time substitutions for climate change. Through field observations in three populations of the North ...

The Behavior And Ecology Of Cursorial Predators And Dangerous Prey: Integrating Behavioral Mechanisms With Population-Level Patterns In Large Mammal Systems, Aimee Tallian

All Graduate Theses and Dissertations

Driving into Yellowstone National Park for the first time is a moving experience. Gazing over the sweeping landscapes, seeing a geyser erupt 80 feet into the air, and having your first ‘wildlife encounter’, whether that be a 2 ton bull bison aggressively wallowing on his dirt mound, snorting and kicking up dust, or watching a pack of 6 wolves move through a valley off in the distance, pausing to howl in search of their companions. Yellowstone staff wishes to manage our park in a way that preserves these remarkable experiences. In order to effectively manage this dynamic ecosystem, it is ...
