Expression Of Facultative Den Behavior In Ursidae, Nicholas Lee Fowler

Theses and Dissertations

Many ecological and evolutionary processes have been described underlying natural selection but supporting evidence in wild settings is often lacking and our understanding remains incomplete. Using a multi-scale approach, I investigated expression of facultative den behavior (denning) among and within ursid species. Among species, lack of denning behavior was supported by relaxation of selection pressures of seasonal food availability due to realization of two sources of ecological opportunity; colonization of new habitat and adaptation of key innovations. Of denning species, I found evidence of adaptive ecological plasticity in den chronology among and within populations consistent with relaxed selective pressures influencing …

Beef Products, Inc. V. Abc News: (Pink) Slimy Enough To Determine The Constitutionality Of Agricultural Disparagement Laws?, Nicole C. Sasaki

Pace Environmental Law Review

This Comment analyzes the likelihood of whether BPI’s case against ABC News will be decided on the merits, whether South Dakota’s agricultural disparagement statute will be upheld as constitutional, and thus the likelihood that other states’ statutes will be struck down, thereby preserving the public’s freedom to question and criticize the safety of our food system. First, Part I offers a brief introduction to agricultural disparagement laws, their historical application, and BPI’s pending lawsuit. Next, Part II reviews the context of the enactment of agricultural disparagement laws, summarizes the common elements of these laws, and discusses Texas Beef Group v. …

The Missing Link: U.S. Regulation Of Consumer Cosmetic Products To Protect Human Health And The Environment, Valerie J. Watnick

Pace Environmental Law Review

This article explores these lax regulatory efforts and their connection to risk assessment, and proposes changes to our current toxics regulatory paradigm. Part I of this article explores our current regulatory approach for consumer cosmetics. Part II discusses the specific and dire concerns regarding chemicals that are suspected carcinogens and those suspected of disrupting the human endocrine system. The article argues in Part III that because the framework for our current regulation of consumer cosmetic products is not designed to be protective of human health, our regulatory paradigm must shift dramatically in the future if this is to become our …

Fraud And First Amendment Protections Of False Speech: How United States V. Alvarez Impacts Constitutional Challenges To Ag-Gag Laws, Larissa U. Liebmann

Pace Environmental Law Review

This article first explains the background and functions of undercover investigations of agricultural production facilities, and explains the bases upon which states pass laws intended to prevent these investigations. It then gives a background of research already conducted on the constitutionality of Ag-Gag laws, and examines the relevance of the Supreme Court case Alvarez. Based on the analysis provided in Alvarez, the article demonstrates that Ag-Gag laws would not be exempt from heightened First Amendment scrutiny as fraud statutes. Moreover, it demonstrates that, in particular, the Iowa and Utah Ag-Gag laws would not survive the heightened scrutiny outlined in Alvarez.

Animal Agriculture Laws On The Chopping Block: Comparing United States And Brazil, Elizabeth Bennett

Pace Environmental Law Review

Brazil and the United States are among the largest producers and exporters of livestock in the world. This raises important animal rights and environmental concerns. While many of the impacts of industrial animal agriculture are similar in Brazil and the United States, there are key differences in the effects on animals and the environment. The variations between Brazil and the United States are due to ecological, production method, and regulatory differences between the countries. Despite their dissimilarities, however, Brazil and the United States both largely fail to adequately protect farm animals and the environment from the impacts of large-scale animal …

Origins And Development Of Teaching Animal Law In Brazil, Tagore Trajano De Almeida Silva

Pace Environmental Law Review

This paper examines the strategies utilized on each continent and shows the path made for these scholars to build a framework to discuss animal law within law schools. The conclusion is that this movement produced by such scholars has changed the way law schools are teaching law and is affording new opportunities to solve animal concerns, and likewise, social problems in Brazil and around the world.

Therefore, this article first discusses the philosophical Brazilian background to teach animal law, and how the animal rights movement creates a framework for professors and students working in this field. It then summarily explores …

Using Emerging Pollution Tracking Methods To Address The Downstream Impacts Of Factory Farm Animal Welfare Abuse, Tarah Heinzen, Abel Russ

Pace Environmental Law Review

CAFOs present numerous interconnected ethical, environmental, and public health threats, and this article will discuss opportunities to address the multiple adverse impacts of factory farming through advances in pollution tracking methodologies. The first section will introduce the factory farm issue, and the relationship between its environmental and welfare consequences. We then review approaches to establishing liability for surface and groundwater contamination under existing pollution control laws and describe the unique challenges of using these approaches in the context of CAFO pollution. We then discuss techniques that have been used to more precisely identify sources of pollution, including measurements of a …

Cultural Solipsism, Cultural Lenses, Universal Principles, And Animal Advocacy, Thomas G. Kelch

Pace Environmental Law Review

Given the potpourri of human cultures and the need to take a global view of animal rights advocacy, how can animal rights advocates most efficiently and successfully advocate for animals? This article will address this issue.

First, I will describe and analyze views of the human/animal relationship from five example cultural traditions: Western culture, represented generally by Europe and North America, Indian culture, Chinese culture, South African culture, and Islamic culture, exemplified primarily here by Turkey. It is not asserted here that any of these cultures or countries are homogenous; they are not. Although Western culture is primarily constructed on …

Foreword, David N. Cassuto

Pace Environmental Law Review

The overlap between animal law and environmental law arises because the two disciplines are fundamentally linked. One cannot talk about the environment without also discussing the nonhuman sentient beings that populate it. Indeed, as I shall discuss shortly, one of the most vexing issues for me— as a scholar working in both fields—involves my ongoing attempt to address the historical tension between the two disciplines. This volume of the Pace Environmental Law Review (PELR) marks an important step on the path toward resolving those tensions and moving environmental law forward. That path will not always be smooth, nor will it …

Reflections On The Conduct Of Research With Human Subjects Across Two Cultures, Kimberly Maas

Journal of Undergraduate Research at Minnesota State University, Mankato

This study examined the potential benefits, challenges, and barriers faced by university students and research colleagues who were involved in international partnerships for cross-cultural research projects between the USA and Russia. In scholarly investigations in the USA, research subjects must be informed of the precautions that will be taken to protect their safety and their privacy (Amdur & Bankfert, 2002). Particularly in Russia, there are no corresponding policies for working with human subjects that compare to the procedures followed by American university Institutional Review Boards. Furthermore, international partnerships have faced new challenges as a result of the restructuring of American …

Group 3 Late Embryogenesis Abundant Proteins From Embryos Of Artemia Franciscana: Structural Properties And Protective Abilities During Desiccation, Leaf C. Boswell, Michael A. Menze, Steven C. Hand

Faculty Research & Creative Activity

Group 3 late embryogenesis abundant (LEA) proteins are highly

hydrophilic, and their expression is associated with desiccation

tolerance in both plants and animals. Here we show that two

LEA proteins from embryos of Artemia franciscana, AfrLEA2

and AfrLEA3m, are intrinsically disordered in solution but

upon desiccation gain secondary structure, as measured by circular

dichroism. Trifluoroethanol and sodium dodecyl sulfate

are both shown to induce a-helical structure in AfrLEA2 and

AfrLEA3m. Bioinformatic predictions of secondary-structure

content for both proteins correspond most closely to conformations

measured in the dry state. Because some LEA proteins

afford protection to desiccation-sensitive proteins during drying

and …

Transcriptome Of American Oysters, Crassostrea Virginica, In Response To Bacterial Challenge: Insights Into Potential Mechanisms Of Disease Resistance, Ian C. Mcdowell, Chamilani Nikapitiya, Derek Aguiar, Christopher E. Lane, Sorin Istrail, Marta Gomez-Chiarri

Biological Sciences Faculty Publications

The American oyster Crassostrea virginica, an ecologically and economically important estuarine organism, can suffer high mortalities in areas in the Northeast United States due to Roseovarius Oyster Disease (ROD), caused by the gram-negative bacterial pathogen Roseovarius crassostreae. The goals of this research were to provide insights into: 1) the responses of American oysters to R. crassostreae, and 2) potential mechanisms of resistance or susceptibility to ROD. The responses of oysters to bacterial challenge were characterized by exposing oysters from ROD-resistant and susceptible families to R. crassostreae, followed by high-throughput sequencing of cDNA samples from various timepoints after …

Guddling About: Experiments In Vital Materialism With Particular Regard To Water, Minty Donald

The Goose

With reference to Jane Bennett’s notion of "vital materialism," this photo essay documents and reflects on Guddling About: a series of experiments or actions carried out by artists Nick Millar and Minty Donald with the Bow River and its watershed in Calgary and Southern Alberta in August-September 2013. Each experiment is described as a set of instructions — a script or score for an event — which can be enacted in any location where human settlement has evolved around a river. The experiments will be repeated, and new ones developed, with the River Clyde in Glasgow and Southern Scotland in …

Bursts And Heavy Tails In Temporal And Sequential Dynamics Of Foraging Decisions, Kanghoon Jung, Hyeran Jang, Jerald D. D. Kralik, Jaeseung Jeong

Dartmouth Scholarship

A fundamental understanding of behavior requires predicting when and what an individual will choose. However, the actual temporal and sequential dynamics of successive choices made among multiple alternatives remain unclear. In the current study, we tested the hypothesis that there is a general bursting property in both the timing and sequential patterns of foraging decisions. We conducted a foraging experiment in which rats chose among four different foods over a continuous two-week time period. Regarding when choices were made, we found bursts of rapidly occurring actions, separated by time-varying inactive periods, partially based on a circadian rhythm. Regarding what was …

Bacterial Symbioses And The Innate Immune Response Of The Model Host: Euprymna Scolopes, Andrew J. Collins

Doctoral Dissertations

All animals enter into beneficial relationships with bacteria. The light organ of the Hawaiian Bobtail squid, Euprymna scolopes, is a unique model for studying the establishment and maintenance of a symbiosis between a host and a single bacterial species, Vibrio fischeri. This bacterium inhabits a specialized structure known as the light organ and provides counter-illumination to mask the silhouette of the predator as it hunts for food during the night. Hemocytes, the primary innate immune cells, preferentially bind and phagocytose non-symbiotic at higher rates than their symbiont, but this can change with the colonization state of the animal. …

Emerging Lexical Organization From Intentional Vocabulary Learning, Adam Jones

Dissertations and Theses

The role that vocabulary learning plays in second language acquisition has been receiving increased attention from both teachers and researchers. However, there is still much that is not known about the processes through which new words become functioning components of the mental lexicon. This study used a word association test (WAT) to investigate how new words are initially integrated into the lexicon immediately after being studied for the first time. This initial lexical organization of new words was compared with the existing lexical organization of well-known items. In addition, this study investigated how sentence writing, thought to encourage deeper levels …

An Epigenetic Look At Atrazine Toxicity: An Analysis Of Microrna-126 Expression In Developing Zebrafish Exposed To The Herbicide Atrazine, Kelly E. Schlotman

The Journal of Purdue Undergraduate Research

Atrazine is a commonly used herbicide in the United States that is reported to contaminate drinking water sources. Studies indicate atrazine adversely impacts the neuroendocrine and reproductive systems, and that it may be a potential carcinogen. The current maximum contaminant level in drinking water is 3 parts per billion (ppb); however, levels higher than 3 ppb are often reported. Ongoing studies in our laboratory are investigating the immediate and latent adverse health outcomes associated with a developmental atrazine exposure and identifying the genetic and epigenetic mechanisms of toxicity using the zebrafish model system. MicroRNAs (miRNAs) are epigenetic regulators that posttranscriptionally …
