Causes And Consequences Of Prolonged Dormancy For An Iteroparous Geophyte, Silene Spaldingii, Peter Lesica, Elizabeth E. Crone

Biological Sciences Faculty Publications

1. Prolonged dormancy, during which a plant does not produce above-ground shoots during one or more growing seasons, is common in temperate herbaceous species, but its role in life history is poorly understood.

2. We analysed stage transitions to determine the consequences of prolonged dormancy for Silene spaldingii, a perennial geophyte of semi-arid grasslands in the Columbia Basin of western North America. We monitored 179 S. spaldingii plants from 1987 through 2005, and analysed demographic rates as a function of plant state and seasonal precipitation.

3. Dormant plants had similar survival and growth to vegetative plants, and were more …

The Return Of The Nightingale, James C. Mckusick

English Faculty Publications

In Ecological Literary Criticism (1994), Karl Kroeber advocated a bold new approach to the study of literature. More than just another routine method of textual analysis, ecological literary criticism seeks to bridge the gap between the natural sciences and the humanities. Such an approach incorporates theoretical advances in the science of environmental biology while it adapts to the changing social and political circumstances of contemporary criticism.

Emissions From Forest Fires Near Mexico City, Robert J. Yokelson, S. P. Urbanski, E. L. Atlas, D. W. Toohey, E. C. Alvarado, J. D. Crounse, P. O. Wennberg, M. E. Fisher, C. E. Wold, T. L. Campos, K. Adachi, P. R. Buseck, Wei Min Hao

The emissions of NOx (defined as NO (nitric oxide) + NO2 (nitrogen dioxide)) and hydrogen cyanide (HCN), per unit amount of fuel burned, from fires in the pine forests that dominate the mountains surrounding Mexico City (MC) are about 2 times higher than normally observed for forest burning. The ammonia (NH3) emissions are about average for forest burning. The upper limit for the mass ratio of NOx to volatile organic compounds (VOC) for these MC-area mountain fires was similar to 0.38, which is similar to the NOx/VOC ratio in the MC urban area emissions inventory of 0.34, but much larger …

The Tropical Forest And Fire Emissions Experiment: Overview And Airborne Fire Emission Factor Measurements, Robert J. Yokelson, T. Karl, Paulo Artaxo, Donald R. Blake, Ted J. Christian, David W. T. Griffith, Alex Guenther, Wei Min Hao

Chemistry and Biochemistry Faculty Publications

The Tropical Forest and Fire Emissions Experiment (TROFFEE) used laboratory measurements followed by airborne and ground based field campaigns during the 2004 Amazon dry season to quantify the emissions from pristine tropical forest and several plantations as well as the emissions, fuel consumption, and fire ecology of tropical deforestation fires. The airborne campaign used an Embraer 110B aircraft outfitted with whole air sampling in canisters, mass-calibrated nephelometry, ozone by UV absorbance, Fourier transform infrared spectroscopy (FTIR), and proton-transfer mass spectrometry (PTR-MS) to measure PM(10), O(3), CO(2), CO, NO, NO(2), HONO, HCN, NH(3), OCS, DMS, CH(4), and up to 48 non-methane …

Exploring Visual Expressions To Articulate Thoughts On Human Existence, Mieko Tachibana

Theses

The purpose of this thesis is to broaden my thoughts on human existence and identity in nature and the universe. It is also to explore the varied visual expressions of my thoughts, feelings, and ways to engage the audiences. ... I tried to experiment with various possible visualizations of my thoughts and feelings through four different installations. Video and installation 1 is about the existence of human beings. In Installation 1, I limited my personal visual images, and instead used language to convey my thoughts. Installation 2 is about the relationship between human beings and nature, and is expressed through …

Acquired Immunodeficiency Syndrome (Aids), David Fleischmann

The Science Journal of the Lander College of Arts and Sciences

Acquired Immunodeficiency Syndrome (AIDS) is a fatal syndrome that affects normally healthy individuals who have acquired an immune system deficiency. AIDS is acquired via a viral agent that attacks the immune system of healthy individuals and eventually erodes it, leading to the onset of a collection of deadly diseases. There are many diseases associated with AIDS, although many of them occur only when an individual has full-blown AIDS. Until then, an infected individual faces several different stages of disease.

Marine Invaders In The Northeast: Rapid Assessment Survey Of Non‐Native And Native Marine Species Of Floating Dock Communities, July 2007, Judy Pederson, Jan Smith

Publications

The 2007 Rapid Assessment Survey (RAS) began in Buzzards Bay, Massachusetts on July 24 and was completed in Rockland, Maine on July 30. Seventeen coastal sites in Massachusetts, New Hampshire and Maine were surveyed, twelve of which were located within four National Estuary Program (NEP) study areas. The following NEPs were included in the study: Buzzards Bay Estuary Program, Massachusetts; Massachusetts Bays Program, Massachusetts; Piscataqua Region Estuaries Partnership, New Hampshire; Casco Bay Estuary Partnership, Maine. In all, twenty‐five non‐native marine species were recorded. Sampling locations are listed below, from south to north. Each listing includes sampling date, time (usually one …
