The Deep Ecology Movement
The International Journal of Ecopsychology (IJE)
There are two great streams of environmentalism in the latter half of the twentieth century. One stream is reformist, attempting to control some of the worst of the air and water pollution and inefficient land use practices in industrialized nations and to save a few of the remaining pieces of wildlands as "designated wilderness areas." The other stream supports many of the reformist goals but is revolutionary, seeking a new metaphysics, epistemology, cosmology, and environmental ethics of person/planet. This paper is an intellectual archeology of the second of these streams of environmentalism, which I will call deep ecology.
Pronghorn Survival And Resource Selection In Western Nebraska's Agriculturally Dominated Landscape,

University of Nebraska-Lincoln
Pronghorn Survival And Resource Selection In Western Nebraska's Agriculturally Dominated Landscape, Katie Piecora
Dissertations & Theses in Natural Resources
Nebraska’s pronghorn population has been stable over the last decade, yet their presence on the landscape remains a contentious subject amongst private landowners. Conversion of grassland for crop production and increased anthropogenic activity has drastically altered pronghorn behavior throughout their current range, however basic ecology and resource use by pronghorn in Nebraska remains poorly understood. Establishing baseline population metrics and seasonal patterns of resource use for this population at the eastern periphery of the species range is critical to guide management actions. We deployed GPS collars on 110 adult pronghorn to quantify survival, mortality risk, and seasonal resource selection in …

Neutral Theory And Beyond: A Systematic Review Of Molecular Evolution Education, Desiree Forsythe, Jeremy L. Hsu
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Molecular evolution—including the neutral theory of molecular evolution—is a major sub-discipline of evolution and is widely taught in undergraduate evolution courses. However, despite its ubiquity, there have not been any previous attempts to compile and review the molecular evolution education literature. Here, we draw upon the framework proposed in a past literature review examining the broader evolution education landscape to conduct a literature review of papers related to molecular evolution education, classifying the contributions of such papers to evolution pedagogy as well as evolution education research. We find that there remains very limited coverage of molecular evolution in the education …
Exploring The Relationships Between Mammalian Functional Trait Distributions And Regional Biomes, With Application To Miocene Paleoecology,
2023
University of Nebraska-Lincoln
Exploring The Relationships Between Mammalian Functional Trait Distributions And Regional Biomes, With Application To Miocene Paleoecology, Devra Hock-Reid
Dissertations & Theses in Earth and Atmospheric Sciences
Paleoecology relies on understanding relationships between modern animals and their environment. Animals are adapted to niches in their environments, and those physical adaptations, or functional traits, are utilized as proxies to interpret aspects of paleo-ecosystems. Much is known about individual functional traits in extant mammals and their relationship to the environment. Less is known about how multiple functional traits across a community can be utilized for paleoecological interpretations. I develop models utilizing traits in mammalian communities at the biome level. For Chapter 1, I build a model for North American regional biomes using mammalian trait frequencies. I quantify changes in …

Holocene Rice Rats (Genus Oryzomys) From The Upper Mississippi River Drainage Basin, Hugh H. Genoways
Zea E-Books Collection
The expansion and collapse of the geographic range of the Texas rice rat (Oryzomys texensis) in the upper Mississippi River drainage basin at the end of the Holocene was a unique event in North American mammals. In a period of about 4000 years with a point of origin near the American Bottom in Illinois, these small rodents extended their geographic range in a straight-line distance of over 950 km to the west into Nebraska and the same distance to the east into Pennsylvania. Then in less than 400 years this range expansion collapsed back to a point where …

Characterization Of Antimicrobial Properties Of Excrement And Functional Microbiome Of Black Vultures (Coragyps Atratus), Bridgette Gray
Theses
Black vultures, Coragyps atratus, are obligate scavenging birds that consume and dispose of decaying carcasses and carrion. They fulfill a key ecological niche in the environments in which they live. It has been observed that these vultures sometimes excrete bodily waste onto their legs. This adaptive behavior could help aid them in controlling bacteria and other microbes they encounter while stepping into a carcass to eat. This study directly examined the antimicrobial properties of the excrement of black vultures across various bacterial species utilizing a zone of inhibition test and a nematode species utilizing a survival assay. The black vulture …

An Analysis Of Lichen Presence On Quercus And Non-Quercus In Chicagoland Area, Shelby Johnson
DePaul Discoveries
Both anthropogenic change and the spread of invasive species have led to changes in urban and forest tree diversity. Oak rust, acute oak decline, and emerald ash borer have all had a detrimental effect on tree species in the Chicagoland area. Quercus species are well known habitats for lichen species including Physcia millegrana, Physcia stellaris, Punctelia rudecta, Flavoparmelia caperata, Xanthomendosa, and Candeleria concolor. Due to the decrease in the traditional Quercus habitats for lichen and the increase in nonnative and nontraditional tree species being introduced, particularly in cities, this study aimed to compare the number and diversity of …
Diversity And Dispersal Among Eastern Continental Divide Headwater Stream Fishes In Gwinnett County, Georgia.,

Georgia Gwinnett College
Diversity And Dispersal Among Eastern Continental Divide Headwater Stream Fishes In Gwinnett County, Georgia., James E. Russell, Molly M. Botting, Ryan M. Davenport, Emilee J. Story, Mark Patterson
Georgia Journal of Science
The eastern continental divide that bisects Georgia runs through Gwinnett County, separating headwater streams of the western Chattahoochee River watershed from headwater streams of the eastern Ocmulgee and Oconee River watersheds. This landscape feature was used to test hypotheses regarding headwater habitat, fish diversity and gene flow. Headwater habitats are dominant components of river network ecosystems delivering vital ecosystem services and biodiversity. Three headwater streams, one in the Chattahoochee watershed and two in the Oconee watershed, on Gwinnett County Park property, were sampled for differences in physical and chemical properties and fish inter- and intraspecific diversity. Our results suggest the …

PLESTIODON EGREGIUS INSULARlS (Cedar Key Mole Skink). REPRODUCTION. Plestiodon egregius insularis is the largest of five described subspecies (Mount 1965. Bull. Florida St. Mus. BioI. Sci. 9:183-213) and is known from only nine small islands off the coast of Levy County, Florida, USA. The only documented clutch size for P. e. insularis contained five eggs (Mount 1963. Am. MidI. Nat. 70:356-385). For wild P. egregius, Mount (1963, op. cit.) reported 2-9 (mean = 4.8) eggs for 13 clutches, and Hamilton and Pollack (1958. Herpetologica 14:25-28) found two nests of P. e. similis in Georgia containing five eggs each. In captivity, …
Hydric Physiology Of Lizards,

California Polytechnic State University, San Luis Obispo
Hydric Physiology Of Lizards, Savannah Weaver
Master's Theses
Chapter 1: Animals can respond to extreme climate by behaviorally avoiding it, or by physiologically coping with it. We understand behavioral thermoregulation and physiological thermal tolerances, but water balance has largely been neglected. Climate change includes both global warming and changes in precipitation regimes, so improving our understanding of organismal water balance is increasingly urgent. We assessed the hydric physiology of endangered Blunt-nosed Leopard Lizards (Gambelia sila) by measuring cutaneous evaporative water loss (CEWL), plasma osmolality, body mass, and body condition throughout their active season. On average, G. sila had low CEWL that is likely desert-adaptive, and high …

A Foundational Population Genetics Investigation Of The Sexual Systems Of Solanum (Solanaceae) In The Australian Monsoon Tropics Suggests Dioecious Taxa May Benefit From Increased Genetic Admixture Via Obligate Outcrossing, Jason T. Cantley, Ingrid E. Jordon-Thaden, Morgan Roche, Daniel S. Hayes, Stephamie Kate, Christopher T. Martine
Faculty Journal Articles
Solanum section Leptostemonum is an ideal lineage to test the theoretical framework regarding proposed evolutionary benefits of outcrossing sexual systems in comparison to cosexuality. Theoretically, non-cosexual taxa should support more genetic diversity within populations, experience less inbreeding, and have less genetic structure due to a restricted ability to self-fertilize. However, many confounding factors present challenges for a confident inference that inherent differences in sexual systems influence observed genetic patterns among populations. This study provides a foundational baseline of the population genetics of several species of different sexual systems with the aim of generating hypotheses of any factor—including sexual system—that influences …

Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino
2023 Symposium
The Schlepp Easement is a 400 acre wetland on the Coeur D’Alene River floodplain, near Cataldo, Idaho. The wetland has been restored to protect it from heavy metal pollution transported downstream from mining sites near Kellogg, Idaho, the location of the Bunker Hill EPA Superfund Site. This wetland was restored to provide safe habitats and feeding grounds for migratory waterfowl and to maintain wetland biodiversity. However, cattail is prone to becoming overdominant and outcompeting other plants, which greatly limits a wetland’s biodiversity. Our objectives were to test whether aquatic boat mowing can reduce cattail cover, improving species diversity and cover …

The Response Of An Avian Community To Intercropping And Forest Management Practices In A Private Working Pine Forest, Rebecca Doyne Bracken
Theses and Dissertations
Within managed pine forest systems, a plethora of bird species exist throughout the lifecycle of a stand akin to what may be experienced through post-disturbance regeneration in a natural forest system. I sought to address how breeding avian communities shift across time in response to stand aging and forest management, evaluate species-specific responses to stand conditions, investigate the responses of at-risk avian species to forest management, and determine avian non-breeding, over-wintering presence in a managed loblolly pine (Pinus taeda) forest. I conducted breeding bird point count and vegetation surveys within five stands of privately owned and managed pine forest in …
An Argument For The Utilization Of Amphibian Stress As An Indicator Of Wetland Condition,

Murray State University
An Argument For The Utilization Of Amphibian Stress As An Indicator Of Wetland Condition, Andrew W. Sisson
Honors College Theses
Traditional forms of rapid wetland condition assessments focus on foliage health, nutrient enrichment, chemical contamination, and surrounding land usage, often overlooking an evaluation of the animals living in the wetland. More intense assessments include the National Wetland Condition Assessment (NWCA) and indices of biotic integrity, which focus on community composition (e.g., diversity and species richness) and abundances. These indices require expertise in species identification and do not provide information about the animal’s fitness. Animal stress physiology, which generally correlates with measures used to quantify animal fitness (e.g., survival, reproduction, and body condition), may provide a complementary rapid assessment method aimed …
Optimizing Strategies To Hydraulically Plant Atlantic Salmon Eggs Based On Fry Dispersal Patterns,

Optimizing Strategies To Hydraulically Plant Atlantic Salmon Eggs Based On Fry Dispersal Patterns, Ernest J. Atkinson
Electronic Theses and Dissertations
The Gulf of Maine Distinct Population Segment of Atlantic Salmon has suffered from habitat loss and exploitation over the last century. Hatchery supplementation has prevented the extirpation of the species, but stocking methods represent tradeoffs between survival, domestication, and logistics. Egg planting, the use of eyed embryos, maximizes natural rearing opportunities which can be important for adaptation. This method, however, is logistically demanding and requires significant labor over large spatial, but short temporal, scales dictated by the ontogeny of the fish. However, the survival and dispersal behavior of Atlantic Salmon fry immediately after emergence from eggs planted in artificial nests …

An Integrative Approach To Modelling Human-Wildlife Coexistence Landscapes In The Northern Great Plains, Keifer Titus
All Dissertations
Restoring wildlife populations in a human dominated world requires a deep understanding of the ecological conditions required for species persistence as well as the human social factors that influence restoration outcomes. Until recently, the majority of prior research has focused on understanding the ecological conditions and human social processes that contribution to wildlife restoration success separately, and often assign a higher value to ecological factors. I studied the human dimensions surrounding ongoing wildlife restoration efforts in the Northern Great Plains (NGP) of Montana to better understand how human social factors can affect and inform restoration efforts for a variety of …

Science, Community, And Culture: A Holistic Approach To Ecological Research And Education, Laura Whipple
All NMU Master's Theses
Global biodiversity has declined at an alarming rate over the past century as a result of many complex human-induced environmental changes. Standardized surveys have historically been used to identify drivers of species declines, but such studies are often resource-intensive, resulting in significant spatial and temporal data gaps when researchers lack the resources necessary to maintain such studies. One promising solution for overcoming gaps in standardized studies is the integration of species observations by community members (e.g., community science). Along with improving modeling techniques to address biodiversity declines, the education of future ecologists on the importance of Indigenous ecological knowledge, robust …
