Lichens Of Pine Hill, A Peridotite Outcrop In Eastern North America, Tanner B. Harris, Fred C. Olday, Nishanta Rajakaruna

Biological Sciences

Despite a large body of work on the serpentine-substrate effect on vascular plants, little work has been undertaken to describe lichen communities growing on serpentine soils derived from peridotite and other ultramafic rocks. Most such work has been conducted in Europe and western North America. Only one study to date has examined the lichen flora of an ultramafic outcrop in eastern North America. The current paper examines the lichen flora of a peridotite outcrop from Deer Isle, Hancock County, Maine, U.S.A. The lichen flora is presented along with relevant ecological and geochemical data. Sixty-three species were found, comprising 35 genera. …

Fundulus As The Premier Teleost Model In Environmental Biology: Opportunities For New Insights Using Genomics, Bernard Rees

Biological Sciences Faculty Publications

A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals and populations interact with their environment. In this paper we summarize an extensive body of work examining the adaptive responses of Fundulus species to environmental conditions, and describe how this research has contributed importantly to our understanding of physiology, gene regulation, toxicology, and ecological and evolutionary genetics of teleosts and other vertebrates. These explorations have reached a critical juncture at which advancement is hindered by the lack of genomic resources for these …

Characterization Of Na+/H+Exchanger-3 (Nhe3) In The Gills Of Longhorn Sculpin (Myoxocephalus Octodecemspinosus), Curtis Eugene Lanier

College of Graduate Studies: Theses & Dissertations

Acid-base regulation is a vital mechanism in homeostasis. Fish must maintain optimal physiological acid-base parameters during changes in an aquatic habitat. Environmental factors such as changes in salinity affect fish ability to maintain optimal blood plasma ion concentrations. Ion regulation influences the fish ability to maintain optimal acid-base balance. The Na+/H+ Exchanger-3 (NHE-3) has been shown to be the primary membrane ion transporter responsible for acid-base balance in the mammalian kidney. The objective of this study is to characterize NHE-3 in the gills of longhorn sculpin (Myoxocephalus octodecimspinosus).

Genetic Evidence For The Persistence Of The Critically Endangered Sierra Nevada Red Fox In California, John D. Perrine, John P. Pollinger, Benjamin N. Sacks, Reginald H. Barrett, Robert K. Wayne

Biological Sciences

California is home to both the native state-threatened Sierra Nevada red fox (Vulpes vulpes necator), which historically inhabited high elevations of the Sierra Nevada and Cascade mountains, and to multiple low-elevation red fox populations thought to be of exotic origin. During the past few decades the lowland populations have dramatically expanded their distribution, and possibly moved into the historic range of the native high-elevation fox. To determine whether the native red fox persists in its historic range in California, we compared mitochondrial cytochrome-b haplotypes of the only currently-known high-elevation population (n = 9 individuals) to samples …

Morphometric Differentiation Of Flank Margin Caves And Littoral, Or Sea Caves, Willapa James Waterstrat

Theses and Dissertations

Caves on carbonate islands are useful indicators of past sea level because cave formation is dependent on sea-level controlled freshwater lens position (flank margin caves), or form in direct contact with coastal processes (sea caves). Sea-level curves present a useful proxy for glacioeustatic and paleoclimate studies, so caves offer useful data. Once a flank margin cave is breached, it may be modified and eroded by waves. This overprinting leads to morphology similar to that of sea caves. While both indicate past sea level, they reveal differing information about the amount of denudation that has occurred to expose them (a paleoclimate …

Regulation Of Human Cystic Fibrosis Transmembrane Conductance Regulator (Cftr) By Serum- And Glucocorticoid-Inducible Kinase (Sgk1), J. Denry Sato, M. Christine Chapline, Renee Thibodeau, Raymond A. Frizzell, Bruce A. Stanton

Dartmouth Scholarship

Background: Serum- and glucocorticoid-inducible kinase-1 (SGK1) increases CFTR Cl currents in Xenopus oocytes by an unknown mechanism. Because SGK increases the plasma membrane expression of other ion channels, the goal of this paper was to test the hypothesis that SGK1 stimulates CFTR Cl currents by increasing the number of CFTR Cl channels in the plasma membrane. Methods: CFTR Cl currents were measured in Xenopus oocytes by the two-electrode voltage clamp technique, and CFTR in the plasma membrane was determined by laser scanning confocal microscopy. Results: wt-SGK1 stimulated CFTR Cl currents by 42% and increased the amount of CFTR in the …

The Art Of Open Spaces Contemporary Sea And Prairiescapes, Elizabeth Schultz

Great Plains Quarterly (through 2013)

Once part of a great inland sea, Kansas and other Great Plains states have been landlocked for millennia. Yet the prairies' "grassy waves" and "islands of cottonwoods" continue to evoke these ancient waters. Diane Quantic in The Nature of the Place: A Study of Great Plains Fiction points out that "[ilt is a rare plains writer who does not invoke the image of the sea of grass, and a rare critic or observer [of the plains] who does not comment upon [this image's] ubiquity." In his index for The Great Prairie Fact and Literary Imagination, under "Prairie, likened to ocean," …
