The Evolution Of Photoperiodic Response Systems And Seasonal Gnrh Plasticity In Birds, Heather E. Watts

Biology Faculty Works

Animals’ lives are typically subdivided into distinct stages, some of which (e.g. breeding) contribute to fitness through enhancing current reproductive success, and some of which (e.g. molting and migration in birds; hibernation in mammals) contribute to fitness through enhancing survival and, therefore, future reproductive opportunities. There is often a trade-off between these two kinds of processes, either because they are temporally incompatible with one another (e.g. migration precludes simultaneous nesting in birds) or because they are energetically incompatible with one another (e.g. successful molting appears to be incompatible with simultaneous nesting in many birds). Consequently, adaptations facilitating appropriate timing and …

Coywolf, Canis Latrans × Lycaon, Pack Density Doubles Following The Death Of A Resident Territorial Male, Eric Strauss

Biology Faculty Works

We studied a subset of four radio-collared individuals that were a part of a larger study documenting Coywolf (Canis latrans × lycaon; Eastern Coyote) ecology in an urbanized landscape (Cape Cod, Massachusetts), and report on the territory of a typical sized pack that was subdivided roughly in half following the death of the breeding male from the original (" Centerville") pack. The original residents lived in a winter pack size (i.e., after pup/juvenile dispersal) of three or four individuals in a 19.66 km territory and a density of 0.15-0.20 individuals/km , as determined by radio-tracking and direct observations, with their …

An Algorithm For Identifying Novel Targets Of Transcription Factor Families: Application To Hypoxia-Inducible Factor 1 Targets, Yue Jiang, Bojan Cukic, Donald A. Adjeroh, Heath D. Skinner, Jie Lin, Qingxi J. Shen, Bing-Hua Jiang

Electrical & Computer Engineering Faculty Research

Efficient and effective analysis of the growing genomic databases requires the development of adequate computational tools. We introduce a fast method based on the suffix tree data structure for predicting novel targets of hypoxia-inducible factor 1 (HIF-1) from huge genome databases. The suffix tree data structure has two powerful applications here: one is to extract unknown patterns from multiple strings/sequences in linear time; the other is to search multiple strings/sequences using multiple patterns in linear time. Using 15 known HIF-1 target gene sequences as a training set, we extracted 105 common patterns that all occur in the 15 training genes …

Proximate Composition, Chlorophyll A, And Carotenoid Content In Dunaliella Salina (Dunal) Teod (Chlorophycea: Dunaliellaceae) Cultured With Cost-Effective Seaweed Liquid Fertilizer Medium, Raghavan Gireesh

Turkish Journal of Botany

Growth, proximate composition, chlorophyll a, and carotenoid content were estimated in static cultures of micro alga Dunaliella salina (Dunal) Teod (Chlorophycea: Dunaliellaceae) to compare the quality and quantity of biomass produced with seaweed liquid fertilizer (SLF) against Walne´s medium. Culture of micro algae was performed with controlled temperature of 27 ± 1 °C, salinity of 33, and an irradiance of 120 ± 3 µ mol m^{-2} s^{-1}, and daily samples were taken to estimate the above-mentioned parameters. Mean cellular density from samples of both medium were similar and growth rates were 0.44 and 0.42 doubling per day, respectively. Maximum values …

Food Habit Of Rana (Pelophylax) Kl. Esculenta Females In A New Recorded E-System Population From A Forested Habitat In North-Western Romania, Istvan Sas, Severus Daniel Covaciu Marcov, Alexandru Strugariu, Anamaria David, Cristina Ilea

Turkish Journal of Zoology

This is the first record of a green frog Rana (Pelophylax) kl. esculenta population from the E-system in the north-western part of Romania. From April to July 2005 we analysed the trophic spectrum of 84 Rana kl. esculenta females, extracting and identifying a total number of 801 prey items. Beside animal preys, plant materials and remains of shed skin were identified in the stomach contents. We did not find any Rana kl. esculenta individuals with empty stomachs. The importance of different animal prey categories varied in certain periods of the study. In the stomach contents collected in July we identified …

Length-Weight Relationships Of Fishes From Gökova Bay, Turkey (Aegean Sea), Tevfi̇k Ceyhan, Okan Akyol, Mustafa Erdem

Turkish Journal of Zoology

Length-weight relationships (LWRs) are presented for 17 fish species caught from Gökova Bay (southeastern Aegean Sea) during the 2006 fishing season. Fish samples were collected from small-scale trammel nets and longline fisheries. The values of b ranged from 2.086 (±0.152) for Sphyraena sphyraena to 3.499 (±0.058) for Scomber japonicus. The median value of b was 3.055 (±0.081). The r^2 values ranged from 0.712 for Sphyraena chrysotaenia to 0.996 for Scomber japonicus and all relationships were highly significant (P < 0.001). Estimated LWR parameters of 4 species, Dicentrarchus labrax, Seriola dumerili, Siganus luridus and Sphyraena sphyraena, for Turkish waters are presented for the first time.

This research was conducted to record the fish species inhabiting Lake Ladik and its inlet and outlet streams between July 2003 and August 2004. Electrofishing equipment, fishing cast net, fisherman's dip net, and fishing nets with different scales were used to catch fish samples. As a result of evaluated samples caught from the research area, 12 species belonging to 4 families (Cyprinidae, Balitoridae, Esocidae, and Percidae) were identified.

The Effect Of Queen Removal On Sexual Production In The Bumble Bee, Bombus Terrestris (Hymenoptera: Apidae), Ayhan Gösteri̇t, Aşkin Gali̇ç, Fehmi̇ Gürel

Turkish Journal of Zoology

We analyzed the effects of queen removal on male and queen production in the bumble bee, Bombus terrestris. In total, 43 Bombus terrestris colonies were reared under standard laboratory rearing conditions. Before the competition point, when the colonies comprised 35-40 workers and many diploid larvae, we removed the queens from 20 randomly selected colonies to test the effects of queenlessness. The timing of gyne production in queenless colonies (25.6 ± 1.5 days) was significantly earlier than in queenright colonies (32.8 ± 3.2 days). Although queen removal had a significant effect on the timing of gyne production, there was no significant …

New Records Of Psilophrys Parvulus And Its Host Kermes Bacciformis From Turkey, George Japoshvili, Mehmet Bora Kaydan, İsmai̇l Karaca

Turkish Journal of Zoology

During 2007-2008 survey conducted on the Turkey oak (Quercus cerris) in Isparta province Psilophrys parvulus (Hymenoptera: Chalcidoidea, Encyrtidae) and its host Kermes bacciformis (Hemiptera: Coccoidea, Kermesidae) represent new species records for Turkey. Previously, P. parvulus was known only from Italy where it was first recorded. The emergence behavior of this parasitoid differs from that of most scale insect parasitoids emerging from the anal opening of its host rather than chewing a hole in the scale insect's test to emerge.

Latina/Os' And Latina/O Legal Studies: A Critical And Self-Critical Review Of Latcrit Theory And Legal Models Of Knowledge Production, Margaret E. Montoya, Francisco Valdes

Faculty Scholarship

For the twelfth time in as many years, the LatCrit community convened its annual conference to underscore the importance of location and locality in the work that we do. The conference theme's framing around Critical Localities: Epistemic Communities, Rooted Cosmopolitans and Knowledge Processes not only focused our collective attention on questions of epistemic community and intellectual (as well as physical) location, but also invited reflection on the meanings we inscribe onto the positions we elect to stake out for ourselves and our work in light of the options and traditions that serve as background. The "Critical Localities" theme invites an …

Spatio-Temporal Dynamics Of Biomes In The Northwestern United States (9000 Ybp To The Present), Christopher Caleb Stump

Graduate Student Theses, Dissertations, & Professional Papers

The goal of this study was to quantitatively analyze and map the vegetation composition of forest, grassland, and steppe ecosystems in the northwestern United States in the present and through the last 9,000 years. The modern analysis used canonical correspondence analysis (CCA) on pollen percentages from recent sediment cores reflecting modern vegetation assemblages and climates to evaluate the amount of influence of selected environmental variables on present species distributions. The fossil analysis used non-metric multi-dimensional scaling (NMDS) on a merged database containing relative pollen percentages from the last 9000 years. A predefined list of environmental parameters and floristically and ecologically …

Territoriality And Habitat Selection Of Feral Pigs On Fort Benning, Georgia, Usa, William Deroche Sparklin

Graduate Student Theses, Dissertations, & Professional Papers

Feral pigs are one of the most successful, widespread, economically and environmentally damaging invasive mammalian species worldwide. I conducted a study of feral pig sounders (female social groups) on Fort Benning, Georgia to test our hypotheses that feral pigs were territorial at the sounder level and that territoriality was a key factor influencing habitat selection of feral pigs. I used Global Positioning System (GPS) location data from 24 individuals representing 18 sounders combined with mark-recapture and camera trap data to evaluate evidence of territorial behavior at the individual and sounder levels by comparing the degree of overlap between home ranges. …

The Elusive "Poem Of The World": The Task Of The Reader And The Problem Of Knowledge In Heinrich Von Kleist's Novellas "Die Marquise Von O..." And "Das Erdbeben In Chili", Lindsey Brandt

Graduate Student Theses, Dissertations, & Professional Papers

The literary works of Heinrich von Kleist (1777–1811) have long been an important influence on thinkers and writers interested and engaged in the German cultural tradition, particularly due to the enigmatic and highly problematic nature of his narrative approach. In recent years, however, there has been a notable surge of interest in Kleist’s works, which has led to the production of several articles, papers, and even entire conference panels dedicated to the investigation of his oeuvre from various angles. Why does Kleist still fascinate his readers so much, and what is it about his texts that allow for such a …

Cognition, Law, Stories, Stephen M. Mcjohn, Lorie Graham

Suffolk University Law School Faculty Works

This essay reviews Steven Pinker, The Stuff of Thought (Penguin 2007), which offers insights from cognitive science just where it overlaps the most with law - how we use basic cognitive categories like intent, space, time, events and causation. The Stuff of Thought might offer insights into a broad range of issues in legal theory. Legal theory could make more use of such cognitive science concepts as chunking, recursion, and the primary qualities of an object. Other topics likewise resonate in thinking about the law: The book suggests that metaphor is an important cognitive tool, but less constraining than might …

An Uneasy Relationship: Combating A Global Threat Through International Trade, Freedom-Kai Phillips

Dalhousie Journal of Legal Studies

Climate change has traversed from the realm of environmental speculation to political policy. No longer is it an issue of lacking scientific evidence; rather it is now an issue of lacking political will. Courageously, the European Union, after gauging the international landscape for a multilateral accord and finding it wanting, has forged forward unilaterally to combat this pressing and substantial threat. In enacting the 20/20 by 2020 the EU has not only set a profound precedent for other developed nations, but has also placed a great burden on its domestic industries. This article examines the EU’s regulatory response, in light …

Of Mice And "Man": Patentability Of Genetic Material And The Protection Of Intellectual Property Rights, Adam Crane

Dalhousie Journal of Legal Studies

The patenting of genetic material raises a host of concerns such as moral and ethical issues, the weakening of the utility requirement and the blockage of downstream research. This article examines the patentability of genetic material in the United States, Canada and the European Union. It discusses the advantages and disadvantages of the current patent system in relation to patents on genetic material. The article concludes with suggestions regarding the protection of intellectual property rights in light of growing concerns.

District Of Columbia V. Heller And Originalism, Lawrence B. Solum

Georgetown Law Faculty Publications and Other Works

On June 26, 2008, the United States Supreme Court handed down its 5-4 decision in District of Columbia v. Heller, striking a District of Columbia statute that prohibits the possession of useable handguns in the home on the ground that it violated the Second Amendment to the United States Constitution. Justice Scalia's majority opinion drew dissents from Justice Stevens and Justice Breyer. Collectively, the opinions in Heller represent the most important and extensive debate on the role of original meaning in constitutional interpretation among the members of the contemporary Supreme Court.

This article investigates the relationship between originalist constitutional …

In this paper, the authors present the applicable laws and legal authorities that public health professionals and lawyers can consider implementing to close the legal gaps identified in the first paper (“Assessing Laws and Legal Authorities for Obesity Prevention and Control”). This set of legal action items encompass the federal, tribal, state, local, and community levels and should be considered when developing, implementing, and evaluating obesity prevention and control strategies and interventions.

The paper organizes the action items within …

A Conditional Intent To Perform, Gregory Klass

Georgetown Law Faculty Publications and Other Works

The doctrine of promissory fraud holds that a contractual promise implicitly represents an intent to perform. A promisor’s conditional intent to perform poses a problem for that doctrine. It is clear that some undisclosed conditions on the promisor’s intent should result in liability for promissory fraud. Yet no promisor intends to perform come what may, so there is a sense in which all promisors conditionally intend to perform.

Building on Michael Bratman’s planning theory of intentions, this article provides a theoretical account of the distinction between “foreground” and “background” conditions on intentions in general and then explains why foreground conditions …

Social Values For Attributes At Risk From Wildfire In Northwest Montana, Derek Timothy O'Donnell

Graduate Student Theses, Dissertations, & Professional Papers

Annual fire management and suppression expenditures by the USDA Forest Service have dramatically increased in recent years, and exceeded $1 billion in the fire seasons of 2000, 2002, 2003, 2006, 2007, 2008, and 2009. These escalating management costs can largely be attributed to the Forest Services’ efforts to protect private property in the wildland-urban interface (WUI) at the expense of other market and non-market attributes. Due to increasing development within the WUI, climate change, and excessive fuel loading from decades of successful fire suppression, it is likely that fire suppression costs will continue to rise if current wildfire management priorities …

Water Quality And Waterborne Disease Along The Niger River, Mali: A Study Of Local Knowledge And Response, Ashley Lauren Williams

Graduate Student Theses, Dissertations, & Professional Papers

This paper presents the findings of a study to assess patterns in local knowledge of and response to water quality and waterborne diseases in relation to seasonal changes in the Niger River Inland Delta. The study draws on field data collected in four villages along the Niger River in the Mopti district of Mali during September 2008. The major findings suggest: (1) water use behaviors and diarrheal disease management are influenced by the tremendous seasonal fluctuations in the riverine environment; (2) local awareness of the relationship between poor water quality, oral-fecal disease transmission, and waterborne disease is low; (3) interventions …

Super Wicked Problems And Climate Change: Restraining The Present To Liberate The Future, Richard J. Lazarus

Georgetown Law Faculty Publications and Other Works

Climate change may soon have its “lawmaking moment” in the United States. The inherent problem with such lawmaking moments, however, is just that: they are moments. What Congress and the President do with much fanfare can quickly and quietly slip away in the ensuing years. This is famously so for environmental law. Subsequent legislative amendments, limited budgets, appropriations riders, interpretive agency rulings, massive delays in rulemaking, and simple nonenforcement are more than capable of converting a seemingly uncompromising legal mandate into nothing more than a symbolic aspirational statement. Climate change legislation is especially vulnerable to being unraveled over time for …

A Taxonomy Of Rules: Authority, Dangers, And Possibilities, Muriel Rebecca Friedman

Graduate Student Theses, Dissertations, & Professional Papers

Rules, originally a means toward group solidarity, are the alternative to the need for ongoing physical dominance. Seemingly omnipresent in modern life, rules can be overt or subtle, explicit or tacit, rigidly enforced or overlooked. They may clash with our autonomy. This thesis names and explores different functional types of rules: safety, personal, socio-cultural, legal-religious, and technical. Rules in general are discussed from social and ethical theoretical viewpoints and using ideal type methodology. Understanding that there are different types of rules and the authority behind them makes it easier to determine one’s obligations to follow them, especially with the notion …

Beyond Wilderness: Wildness As A Guiding Ideal, Christopher James Dunn

Graduate Student Theses, Dissertations, & Professional Papers

This thesis is largely a response to William Cronon’s essay “The Trouble with Wilderness or Getting Back to the Wrong Nature,” found in The Great New Wilderness Debate. Cronon is himself responding to many things, in large part to Bill McKibben’s The End of Nature and also to the wilderness vision typified by Dave Foreman; thus this thesis is also a response to McKibben and in many respects a defense of Foreman-like thought. Besides Cronon, I consider a wide variety of sources, taking from them in order to build a case for, and to explicate, wildness as a guiding ideal. …

Biogenesis, Assembly And Intracellular Trafficking Of Junin Arenavirus Envelope Glycoprotein Complex, Sudhakar Srinivasarao Agnihothram

Graduate Student Theses, Dissertations, & Professional Papers

An unusual feature in the arenavirus envelope glycoprotein complex (GP-C) is the presence of a myristoylated stable signal peptide (SSP) in addition to the receptor binding subunit G1 and the transmembrane fusion subunit G2. Genetic studies were employed to understand the structure-function of the GP-C complex, with emphasis on elucidating the role of SSP in arenavirus life cycle. We present genetic evidence that support the inclusion of G2 as a member of Class I viral fusion protein, where membrane fusion is mediated by six-helix bundle structure as in HIV and Influenza viruses. Furthermore, we have identified crucial roles for SSP …

An Investigation Of Spatial And Temporal Variability In Several Of Montana's Reference Streams: Working Toward A More Holistic Management Strategy, Kathryn Elizabeth Makarowski

Graduate Student Theses, Dissertations, & Professional Papers

Water temperature is a physical property that fundamentally affects stream ecology and is considered an important water quality parameter from scientific and legal view points. On global, catchment and reach scales, anthropogenic activities have substantially altered natural stream temperature regimes, impairing these systems’ ability to maintain ecological integrity. Thermal degradation often can be attributed to a variety of human activities, and global climate change, which has been accelerated by the demands of an exponentially expanding human population, will play a central role in defining stream temperature regimes in the future. Natural spatial and temporal variability in stream temperatures adds to …
