Genetic Evidence For Long-Term Population Decline In A Savannah Dwelling Primate: Inferences From A Hierarchical Bayesian Model, Jay F. Storz, Mark A. Beaumont, Susan C. Alberts Jul 2002

Genetic Evidence For Long-Term Population Decline In A Savannah Dwelling Primate: Inferences From A Hierarchical Bayesian Model, Jay F. Storz, Mark A. Beaumont, Susan C. Alberts

Jay F. Storz Publications

The purpose of this study was to test for evidence that savannah baboons (Papio cynocephalus) underwent a population expansion in concert with a hypothesized expansion of African human and chimpanzee populations during the late Pleistocene. The rationale is that any type of environmental event sufficient to cause simultaneous population expansions in African humans and chimpanzees would also be expected to affect other codistributed mammals. To test for genetic evidence of population expansion or contraction, we performed a coalescent analysis of multilocus microsatellite data using a hierarchical Bayesian model. Markov chain Monte Carlo (MCMC) simulations were used to estimate …


Immunophylogenetic Aspects Of A Gorgonian Coral, Larry J. Dishaw Jul 2002

Immunophylogenetic Aspects Of A Gorgonian Coral, Larry J. Dishaw

FIU Electronic Theses and Dissertations

One goal of comparative immunology is to derive inferences about evolutionary pathways in the development of immune-defense systems. Almost 700 million years ago, a major divergence occurred in the phylogeny of animals, spitting all descendants into either the protostome or deuterostome (includes vertebrates) lineages. Genes have evolved independently along these lineages for that amount of time. Cnidarians originated before that divergence event, and can hold clues as to which immune response genes are homologous to both lineages. This work uses the gorgonian coral, Swiftia exserfa, for two major reasons: 1) because of their phylogenetic position, corals are an important …


An Assessment Of Potential Habitat Corridors And Landscape Ecology For Long-Tailed Macaques (Macaca Fascicularis) On Bali, Indonesia, Mark Warren Southern Jun 2002

An Assessment Of Potential Habitat Corridors And Landscape Ecology For Long-Tailed Macaques (Macaca Fascicularis) On Bali, Indonesia, Mark Warren Southern

All Master's Theses

The relationship between Balinese long-tailed macaques, Bali's cultural settings, and Bali's physical settings was studied. A Geographical Information System (GIS) database was developed and analyzed to determine if forest corridors exist on Bali that may provide habitat connectivity between 42 Balinese long-tailed macaque troops. The GIS database was also analyzed to determine if the landscape type that has the highest percentage of overlap with the 42 Balinese long-tailed macaque home range sites is forest. The results indicate that connectivity between troops located within Bali's western region is significantly higher than that for troops located in Bali's eastern region. The results …


Applied Ethics In Animal Research: Philosophy, Regulation, And Laboratory Applications, John P. Gluck, Tony Dipasquale, F. Barbara Orlans Jan 2002

Applied Ethics In Animal Research: Philosophy, Regulation, And Laboratory Applications, John P. Gluck, Tony Dipasquale, F. Barbara Orlans

Purdue University Press Books

This volume is a collection of chapters all contributed by individuals who have presented their ideas at conferences and who take moderate stands with the use of animals in research. Specifically the chapters bear of the issues of: notions of the moral standings of animals, history of the methods of argumentation, knowledge of the animal mind, nature and value of regulatory structures, how respect for animals can be converted from theory to action in the laboratory. The chapters have been tempered by open discussion with individuals with different opinions and not audiences of true believers. It is the hope of …


Adaptive Functions Of The Corpus Striatum: The Past And Future Of The R-Complex, Neil Greenberg Jan 2002

Adaptive Functions Of The Corpus Striatum: The Past And Future Of The R-Complex, Neil Greenberg

Neil Greenberg

The basal ganglia is emerging from the shadow cast by the most conspicuous clinical expression of its dysfunction: motor disorders.What is revealed is the nexus of a widely distributed system which functions in integrating action with cognition, motivation, and affect. Prominent among non-motor functions are striatal involvement in building up of sequences of behavior into meaningful, goal-directed patterns and repertoires and the selection of appropriate learned or innate sequences in concert with their possible predictive control. Further, striatum seems involved in declarative and strategic memory (involving intentional recollection and the management of retrieved memories, respectively). Findings from reptile experiments indicate …

Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn Jan 2002

Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn

Human and Animal Bonding Collection

The subject of wolf recovery in North America sparks heated controversy, both for and against. This paper explores how this subject is informed by cosmopolitan worldviews. These worldviews pull nature and culture into a common orbit of ethical meaning, with implications for the normative relationships that ought to pertain in landscapes shared by people and wolves. This theoretical outlook is illustrated using the controversy over wolves in the northeastern region of the United States. I conclude with a set of reflections on theorizing the cosmopolis, the interpretation of cosmopolitan landscapes, and living with cosmopolitan wolves.
