Traversing Swanton Road, 5th Ed., James A. West Apr 2011

Traversing Swanton Road, 5th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Involvement Of Protein Kinase C And Protein Kinase A In The Enhancement Of L-Type Calcium Current By GabaB Receptor Activation In Neonatal Hippocampus, Jennifer Grace Bray, Michelle Mynlieff Apr 2011

Involvement Of Protein Kinase C And Protein Kinase A In The Enhancement Of L-Type Calcium Current By GabaB Receptor Activation In Neonatal Hippocampus, Jennifer Grace Bray, Michelle Mynlieff

Biological Sciences Faculty Research and Publications

In the early neonatal period activation of GABAB receptors attenuates calcium current through N-type calcium channels while enhancing current through L-type calcium channels in rat hippocampal neurons. The attenuation of N-type calcium current has been previously demonstrated to occur through direct interactions of the βγ subunits of Gi/o G-proteins, but the signal transduction pathway for the enhancement of L-type calcium channels in mammalian neurons remains unknown. In the present study, calcium currents were elicited in acute cultures from postnatal day 6–8 rat hippocampi in the presence of various modulators of protein kinase A (PKA) and protein kinase C …

Estrogenic Regulation Of The Immune System In A Murine Model For Systemic Lupus Erythematosus, Matthew James Zuber Apr 2011

Estrogenic Regulation Of The Immune System In A Murine Model For Systemic Lupus Erythematosus, Matthew James Zuber

Biology Honors Papers

Systemic Lupus Erythematosus is a damaging autoimmune disease afflicting millions of people worldwide. Lupus is characterized by an overabundance of autoantibodies, proteins directing the immune system to destroy a person's own body, what it would normally be protecting. The molecular mechanisms, environmental influences, and genetic predispositions of Lupus are not yet fully understood. However, nine out of ten Lupus patients are women between the age of puberty and menopause, when estrogen levels are highest. The fact that women are significantly more prone to suffer from Lupus than men leads experts to believe that the sex hormone estrogen which is present …

Biological Sciences Faculty Publications

Wind energy offers the potential to reduce carbon emissions while increasing energy independence and bolstering economic development. However, wind energy has a larger land footprint per Gigawatt (GW) than most other forms of energy production, making appropriate siting and mitigation particularly important. Species that require large unfragmented habitats and those known to avoid vertical structures are particularly at risk from wind development. Developing energy on disturbed lands rather than placing new developments within large and intact habitats would reduce cumulative impacts to wildlife. The U.S. Department of Energy estimates that it will take 241 GW of terrestrial based wind development …

Prevalence Of Methicillin Resistant Staphylococcus Aureus On Computer Mice On The Campus Of Southern Adventist University, Aldo J. Espinoza Apr 2011

Prevalence Of Methicillin Resistant Staphylococcus Aureus On Computer Mice On The Campus Of Southern Adventist University, Aldo J. Espinoza

Capstone Research Projects

Microorganisms are present everywhere in the environment. Unbeknownst to most people Staphylococcus aureus is a primary pathogen responsible for many skin infections and is carried by 25% of humans in the anterior nares. Due to the infective nature of Staphylococcus aureus, it is important to determine its prevalence on fomites by testing commonly used surfaces. For these reasons a research experiment was designed to determine the prevalence of S. aureus and Methicillin Resistant S. aureus (MRSA) in computer labs on the campus of Southern Adventist University during the fall semester of 2010. The research experiment was conducted in computer labs …

Episodic Radiations In The Fly Tree Of Life, Brian M. Wiegmann, Michelle D. Trautwein, Isaac S. Winkler, Norman B. Barr, Jung-Wook Kim, Christine Lambkin, Matthew Bertone, Brian Cassel, Keith Bayless, Alysha Heimberg Apr 2011

Episodic Radiations In The Fly Tree Of Life, Brian M. Wiegmann, Michelle D. Trautwein, Isaac S. Winkler, Norman B. Barr, Jung-Wook Kim, Christine Lambkin, Matthew Bertone, Brian Cassel, Keith Bayless, Alysha Heimberg

Dartmouth Scholarship

Flies are one of four superradiations of insects (along with beetles, wasps, and moths) that account for the majority of animal life on Earth. Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila melanogaster). A resolved phylogeny for flies provides a framework for genomic, developmental, and evolutionary studies by facilitating comparisons across model organisms, yet recent research has suggested that fly relationships have been obscured by multiple episodes of rapid diversification. We provide a phylogenomic …

Dopamine’S Role In Ethanol Induced Behavioral Disinhibition, Erick Saldes^, Kyung-An Han* Apr 2011

Dopamine’S Role In Ethanol Induced Behavioral Disinhibition, Erick Saldes^, Kyung-An Han*

COURI Symposium Abstracts, Spring 2011

Ethanol is commonly associated with disinhibited motor and sexual behaviors in humans. Dopamine and serotonin are implicated in these processes since they regulate reward, motivation, aggression, movement control, and sexual behavior. Disinhibited behavior such as impulsivity (loss of impulse control) is also related to addiction. The major goal of this study is to identify the role of dopamine in disinhibited behavior using the genetic model system, Drosophila melanogaster.  For this task we developed a novel apparatus called Flypub. It is a plastic chamber with a clear top for recording and monitoring fly behavior before, during, and after ethanol exposure. …

Eight Criticisms Not To Make About Group Selection, Omar Tonsi Eldakar, David Sloan Wilson Apr 2011

Eight Criticisms Not To Make About Group Selection, Omar Tonsi Eldakar, David Sloan Wilson

Biology Faculty Articles

Group selection, which was once widely rejected as a significant evolutionary force, is now accepted by all who seriously study the subject. There is still widespread confusion about group selection, however, not only among students and the general public, but among professional evolutionists who do not directly study the subject. We list eight criticisms that are frequently invoked against group selection, which can be permanently laid to rest based upon current knowledge. Experts will always find something to critique about group selection, as for any important subject, but these eight criticisms are not among them. Laying them to rest will …

The Truth About Models: How Well Do Mechanical Models Mimic The Observed Gender Distributions In Two-Child Families?, William D. Stansfield, Matthew A. Carlton Apr 2011

The Truth About Models: How Well Do Mechanical Models Mimic The Observed Gender Distributions In Two-Child Families?, William D. Stansfield, Matthew A. Carlton

Biological Sciences

We question the use of mechanical models, such as coin flipping, to represent the probabilities of gender distributions in sibship families consisting of two children. Both the assumptions of the models and the reliability of the data should be evaluated. Using models without these critical evaluations may tend to perpetuate myths rather than elucidate biological realities.

Geographic Variation In Temperature Tolerance As An Indicator Of Potential Population Responses To Climate Change, Cascade J.B. Sorte, Sierra J. Jones, Luke P. Miller Apr 2011

Geographic Variation In Temperature Tolerance As An Indicator Of Potential Population Responses To Climate Change, Cascade J.B. Sorte, Sierra J. Jones, Luke P. Miller

Faculty Publications, Biological Sciences

The temperature tolerances of individuals in geographically separated populations of a single species can be used as indicators of each population's potential to persist or become extinct in response to climate change. We evaluated the population-level variation in temperature tolerance in populations of several marine invertebrate taxa, including bryozoans, tunicates, bivalves, and gastropods, separated by distances of < 200 km to > 5000 km. We then combined physiological thermotolerance data with current temperature data and climate change predictions to predict which of these populations may be most vulnerable to future changes. In a trans-continental comparison of four subtidal epibenthic species, we show that populations on …
