Shakespeare's Blush, Or "The Animal" In Othello, Steven Swarbrick
Shakespeare's Blush, Or "The Animal" In Othello, Steven Swarbrick
Publications and Research
This essay examines how the rhetoric of animalization in Shakespeare’s Othello compels us to think early modern categories of race in connection with early modern discourses of “human” versus “animal.” Beginning with Shakespeare’s representation of Iago, I suggest that it is the potential for sameness conditioned by Iago’s counterfactual statement (“Were I the Moor, I would not by Iago”) that is most significant about his relation to Othello. From there I consider the overlap between the play’s representations of animality and black skin. Read in the context of Jacques Derrida’s reflections on animals, I consider the deconstructive value of linking …

Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. This has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require it. Nevertheless, ecological restoration remains a young and rapidly growing discipline and its intersection with toxicology is even more nascent and underdeveloped. Consequently, we provide guidance to scientists and practitioners on when, where, and how to restore contaminated ecosystems. Although restoration has many benefits, it also can be expensive, and in many cases systems can recover without human intervention. Hence, the first question we address is: "When …

Dispersal And Sampling Of The Wheat Stem Sawfly, Cephus Cintus Norton, (Hymenoptera: Cephidae), Christopher Mccullough
Department of Entomology: Dissertations, Theses, and Student Research
The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a serious insect pest of wheat, Triticum aestivum L., in the northern central Great Plains. The sawfly has been a pest of wheat in Montana, North Dakota, and Canada since the early 20th century. It was first detected in Nebraska winter wheat in the early 1990s, in Scotts Bluff County. The sawfly has since spread throughout the Nebraska Panhandle region and become a pest of serious concern. To gain a better understanding of the sawfly in Nebraska, investigations on the emergence, dispersal, and sampling of the sawfly were conducted. …

Individuals with cystic fibrosis (CF) often acquire chronic lung infections that lead to irrevers- ible damage. We sought to examine regional variation in the microbial communities in the lungs of individuals with mild-to-moderate CF lung disease, to examine the relationship between the local microbiota and local damage, and to determine the relationships between microbiota in samples taken directly from the lung and the microbiota in spontaneously expectorated sputum. In this initial study, nine stable, adult CF patients with an FEV1>50% underwent regional sampling of different lobes of the right lung by bronchoalveolar lavage (BAL) and protected brush (PB) sampling …

A Systems Approach To Animal Communication, Eileen A. Hebets, Andrew B. Barron, Christopher N. Balakrishnan, Mark E. Hauber, Paul H. Mason, Kim L. Hoke
Eileen Hebets Publications
Why animal communication displays are so complex and how they have evolved are active foci of research with a long and rich history. Progress towards an evolutionary analysis of signal complexity, however, has been constrained by a lack of hypotheses to explain similarities and/or differences in signalling systems across taxa. To address this, we advocate incorporating a systems approach into studies of animal communication—an approach that includes comprehensive experimental designs and data collection in combination with the implementation of systems concepts and tools. A systems approach evaluates overall display architecture, including how components interact to alter function, and how function …

Chemical Investigation Of Antarctic Marine Organisms & Their Role In Modern Drug Discovery, Jacqueline Lee Fries
USF Tampa Graduate Theses and Dissertations
The chemicals produced by biological systems, whether proteins, peptides, or terpenes, will always provide an intriguing topic for researchers. Invisibly controlling every aspect of nature, these molecules are responsible for life, evolution, and death. Specifically, here is described the secondary metabolites produced by Antarctic marine organisms as well as others, and how they are used to defend or attract other animals while potentially providing health benefits to mankind. This is done through collection, extraction, and separation of individual specimens. The respective mixtures of compounds after isolation are then analyzed via spectroscopic methods such as nuclear magnetic resonance spectroscopy, mass spectrometry, …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
In the present study, we surveyed the diversity of scorpions in six provinces of Mongolia (Bayankhongor, Khovd, Dundgovi, Dornogovi, Govisümber and Ömnögovi) between 2001 and 2012. A total of 385 individuals were collected at 17 different sites. In addition to opportunistic sampling, animals were collected after detection with ultraviolet light. Only species from the genus Mesobuthus have been reported from Mongolia thus far. It was possible to confirm the occurrence of the species Mesobuthus eupeus mongolicus and report the presence of M. martensii martensii for the first time. We could not confirm the presence of M. caucasicus przewalskii and suggest …

Given the complexity of host-microbiota symbioses, scientists and philosophers are asking questions at new biological levels of hierarchical organization—what is a holobiont and hologenome? When should this vocabulary be applied? Are these concepts a null hypothesis for host-microbe systems or limited to a certain spectrum of symbiotic interactions such as host-microbial coevolution? Critical discourse is necessary in this nascent area, but productive discourse requires that skeptics and proponents use the same lexicon. For instance, critiquing the hologenome concept is not synonymous with critiquing coevolution, and arguing that an entity is not a primary unit of selection dismisses the fact that …

During a series of studies on the population, ecology, and biology of the Cinereous Vulture in Mongolia, fully feathered nestlings of the species from 9 nests were examined, without the use of chemical methods, for Mallophaga infestation from 2010 to 2015. The collection resulted in several first records for Mongolia of three species: Laemobothrion vulturis (J. C. FABRICIUS, 1775) sensu lato (Amblycera, Laemobothriidae), Neocolpocephalum aegypii (TENDEIRO, 1989) (Amblycera, Menoponidae s. l.) sp. inq., and Falcolipeurus quadripustulatus (BURMEISTER, 1838) (Ischnocera, Philopteridae s. l.). Despite being expected, there has still been no record of Agypoecus brevicollis (BURMEISTER, 1838) in Mongolia.

Numerous studies show that increasing species richness leads to higher ecosystem productivity. This effect is often attributed to more efficient portioning of multiple resources in communities with higher numbers of competing species, indicating the role of resource supply and stoichiometry for biodiversity–ecosystem functioning relationships. Here, we merged theory on ecological stoichiometry with a framework of biodiversity–ecosystem functioning to understand how resource use transfers into primary production. We applied a structural equation model to define patterns of diversity– productivity relationships with respect to available resources. Meta-analysis was used to summarize the findings across ecosystem types ranging from aquatic ecosystems to grasslands …

Soil Properties Affect Establishment Of Invasive Species, Celastrus Orbiculatus, In A Lower Hudson River Riparian Ecosystem, Shabana Hoosein Hoosein
Legacy Theses & Dissertations (2009 - 2024)
The Hudson River Estuary has been colonized by numerous terrestrial invasive plant species, due in part to its history of anthropogenic and natural disturbance riparian dynamics. This study investigates the spatial patterns of a widespread invasion by Oriental (or Asiatic) bittersweet (Celastrus orbiculatus Thunb.) in Schodack Island State Park, Rensselaer and Columbia Counties. The Park is home to rare species and communities, several of which are threatened by the encroachment of bittersweet. Bittersweet populations were mapped and surveyed on a fixed grid throughout the island, to determine distribution patterns. Stem densities were approximately 50% higher in sites with dredged material …

I conducted a mark-recapture study to assess the natural history of a Neotropical salamander community in three discrete 4–6 week sampling periods at Chorro Las Yayas, a protected natural area of about 8000 m2 in central Panama, during an extended drought. I captured 87 Bolitoglossa biseriata, 17 Oedipina complex, and 15 O. parvipes. Bolitoglossa biseriata, had a mean mass of 0.8 ± 0.4 g with a mean snout-vent length (SVL) of 31.45 ± 5.30 mm. Bolitoglossa biseriata was active throughout the night, and its detection rate varied with season, air temperature, and amount of precipitation in the previous 24 h. …
Organismal Composition And Photosynthetic Traits Of Biological Soil Crusts In Prairie Ecosystems Of The Great Plains, Brendon C. Mccampbell
Organismal Composition And Photosynthetic Traits Of Biological Soil Crusts In Prairie Ecosystems Of The Great Plains, Brendon C. Mccampbell
Master's Theses or Doctor of Nursing Practice
Biological soil crusts (BSCs) are soil-surface microecosystems composed of a close association of algae, cyanobacteria, fungi, lichens, and non-vascular plants with soil particles. BSCs have several ecological functions including carbon fixation, nitrogen fixation, nutrient relations, soil stabilization, water relations, and floral community development, which make them extremely important in many of the ecosystems where they occur. While BSCs have been studied throughout the American West, little work has been done in the Great Plains region where they are less prominent among the dominant vascular plant communities. This study examined organismal composition and photosynthetic traits of BSCs in four ecosystems within …

Ecology Of Two Reintroduced Black Bear Populations In The Central Appalachians, Sean Mccarthy Murphy
Theses and Dissertations--Animal and Food Sciences
Reintroduced populations are vulnerable to demographic and environmental stochasticity, deleterious genetic effects, and reduced population fitness, all of which can increase extinction probability. Population viability is principle to determining the status of reintroduced populations and for guiding management decisions. To attempt to reestablish black bear (Ursus americanus) populations in the central Appalachians, two reintroductions using small founder groups occurred during the 1990s in the Big South Fork area along the Kentucky-Tennessee border (BSF) and in the Jefferson National Forest along the Kentucky-Virginia border (KVP). My objectives were to estimate demographic and genetic parameters, and to evaluate long-term viability …
Species Distribution Modeling Of North American Odonates, Rebecca Beilinson
Species Distribution Modeling Of North American Odonates, Rebecca Beilinson
Library Map Prize
Species distribution modeling, which uses species-environment relationships to predict species’ geographic ranges, is a powerful technique for biogeographical and ecological analysis as well as for conservation planning. However, it has typically been underutilized for invertebrates and for freshwater species, as modeling these groups can pose unique challenges. Here I present methods for modeling odonate distributions and demonstrate these methods for four North American species. I show that incorporating expert-derived range maps as spatial priors can significantly improve model performance as compared to MaxEnt models. I also introduce a new distance to freshwater layer as an environmental variable, and show that …

Activity Patterns, Home Range, And Microhabitat Selection Of A Terrestrial Turtle (Rhinoclemmys Rubida Perixantha) In A Tropical Dry Forest, Taggert G. Butterfield
All Master's Theses
Turtles are in trouble worldwide, with nearly half recognized by the International Union for Conservation of Nature (IUCN) as needing special protection. The Eurasian pond and Neotropical wood turtles of the family Geoemydidae are the most diverse turtles and comprise ¼ of all turtle species yet basic information on their natural history is lacking. Moreover, seasonal tropical dry forest (SDTF), where many geoemydids exist, is considered the most endangered ecosystem in the world. We investigated the activity patterns, home range size, and microhabitat selection of the Mexican Spotted Wood Turtle (Rhinoclemmys rubida perixantha) in its SDTF habitat by …

An Examination Of Plant Community Composition In Six Carolina Bays On The Coastal Plain Of South Carolina, Katherine L. Altman-Goff
Electronic Theses and Dissertations
Historically high rates of human impact and recent Supreme Court cases, which have affected the regulation of geographically isolated wetlands in the United States, suggest that Carolina bays may be at high risk of human impacts in the future. Conservation efforts should be established based on applied ecological data and, if regulations by state and federal agencies are unable to conserve Carolina bay wetlands, it may be important to prioritize individual bays for preservation on protected lands. I examined plant community composition, diversity, richness, and rarity and soil parameters in six Carolina bays across South Carolina, using a replicated ecological …

Plant Functionality Across An Environmental Gradient, Taylor L. Price, Julie Zinnert
UROP Posters
Community assemblages provide insight into ecosystem processes, both spatially and temporally. They interact with biotic and abiotic factors that vary with habitat structure, influencing community composition. Ecological theory demonstrates that species have the potential for a wide fundamental niche, but habitat range may be restricted by factors exposed to species in their realized niche. In barrier island ecosystems, edaphic and environmental characteristics (e.g. elevation and distance to shoreline) are major drivers determining where and how plant communities establish. Physical stressors, such as salt stress and drought influence community grouping and can alter plant function within the environment. With projected increases …
Resurgence Of Acropora Corals On Mid Shelf Patch Reefs, Southwater Caye Marine Reserve, Central Belize, Jillian J. Keefer
Resurgence Of Acropora Corals On Mid Shelf Patch Reefs, Southwater Caye Marine Reserve, Central Belize, Jillian J. Keefer
Undergraduate Honors Thesis Projects
Acropora cervicornis (staghorn) and Acropora palmata (elkhorn) are ecologically important corals that grow quickly and provide topography and refuges for fish and invertebrates. Historically, Acropora was the most abundant coral in shallow patch reef zones in the Caribbean. During the 1980s, white band disease eliminated most Acropora causing a loss in rugosity and an increase of macroalgae on many reefs. Although Acropora remains rare throughout most of the Caribbean, this study documents its partial comeback and possible limiting factors in Southwater Caye Marine Reserve (SWCMR), Central Belize. Patch reefs in the reserve averaged 19% live coral cover with A. palmata …

Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel
Cal Poly Humboldt theses and projects
Wildlife-habitat relationship studies are important for understanding the factors that determine where species occur in space and time. Habitat selection by generalist species should be studied on fine spatial and temporal scales to avoid masking important differences between seasons, localities, or orders of selection. I conducted the first study of habitat use and general ecology of North American porcupines (Erethizon dorsatum) in a coastal dune environment. Specifically, I assessed changes in body mass, home range size, and habitat selection in relation to the potential for seasonal nutritional and survival bottlenecks as reported elsewhere. Although they are considered generalists, …

Coyotes have been slowly moving into New York State from Canada since the 1930s. They reached Westchester County and the Bronx decades ago, and their numbers have been slowly rising. Sighting in Manhattan reached an all-time high last spring, and pet attacks in Westchester County have increased slightly in the last several years. But the slight increase in sightings and pet attacks in recent years has been amplified on social media in towns like Chappaqua, New York, where anxiety and fear about coyotes has pitted neighbors against neighbors.

Examining Sociological Differences And The Influence Of Prey Distribution And Environmental Variability In The Distribution Of A Top Marine Predator, The Bottlenose Dolphin (Tursiops Truncatus), Stefanie K. Gazda
Graduate Doctoral Dissertations
The purpose of this dissertation was to examine the influence of environmental variability on the distribution of prey, and the influence of prey spatial structure and habitat variability may have on the distributions of bottlenose dolphins (Tursiops truncatus). Additionally I examined how sociological differences (behavior type and the changes in a foraging behavior specific to Cedar Key Florida) influences the relative roles of bottlenose dolphins within the population.
The Gowans et al. scheme assumes that small groups form small communities and that foraging groups are small and rare as there are few foraging benefits to promote grouping. Using network analysis, …

An Invasive Grass And A Desert Adapted Rodent: Is There An Effect On Locomotory Performance And Is It Modified By Prior Experience Or Familiarization?, Camille D. Boag
Master's Theses
Kangaroo rats (Dipodomys spp.) are frequently characterized as keystone species for their role in altering soil characteristics, changing habitat structure through seed consumption and dispersal, and being important primary consumers in their ecosystem. They are arid adapted and known to forage in areas with sparse vegetation. Studies suggests densely vegetated habitat to be unsuitable for kangaroo rats because plants are an impediment to their locomotion and predator avoidance behaviors. This study focuses on an invasive grass, South African Veldt (Ehrharta calycina), that converts landscapes with sparse vegetation into dense grassland habitats, and the Lompoc kangaroo rat …
