Bird Use Of Riparian Vegetation Along The Truckee River, Califonia And Nevada, Suellen Lynn, Michael L. Morrison, Amy J. Kuenzi, Jennifer C. C. Neale, Benjamin N. Sacks, Robin Hamlin, Linnea S. Hall

Great Basin Naturalist

The Truckee River in California and Nevada is subject to diverse water regimes and a corresponding variety of flow rates. Original riparian vegetation has been altered by these variable flow rates and by a variety of human uses resulting in loss of native riparian vegetation from its historic extent. We conducted bird surveys along the Truckee River during spring 1993 to (1) determine relationships between birds and the present vegetation; (2) determine the importance of different vegetation types to sensitive bird species that have declined recently in the western United States due to competition from exotic plant species, cowbird ( …

Gap Analysis Of The Vegetation Of The Intermountain Semi-Desert Ecoregion, David M. Stoms, Frank W. Davis, Kenneth L. Driese, Kelly M. Cassidy, Michael P. Murray

Great Basin Naturalist

A conservation gap analysis was conducted for the Intermountain Semi-Desert ecoregion to assess the representation of land-cover types within areas managed primarily for biodiversity objectives. Mapped distributions of plant communities were summarized by land-management status categories. The total amount of land permanently protected in the ecoregion is

Winter Macroinvertebrate Communities In Two Montane Wyoming Streams, Christopher M. Pennuto, Frank Denoyelles Jr., Mark A. Conrad, Frank A. Vertucci, Sharon L. Dewey

Great Basin Naturalist

Macroinvertebrate communities were examined on 4 winter dates over a 4-yr period in 2 high-altitude Rocky Mountain streams to document overwintering assemblages potentially experiencing spring acid pulses. Taxa richness values were comparable to other published lists for alpine and montane stream systems despite the fact that most literature reflected summer collections. Mean benthic density ranged from 1406 to 19,734 organisms/m², and drift rates ranged from 0 to 1740 organisms/100 m³. Benthic collections showed higher taxa richness than drift collections while the Ephemeroptera and Plecoptera occurred in greater proportions in drift than in benthos. The Nemouridae (Plecoptera), …

Maine Lumber Production, 1839-1997: A Statistical Overview, Lloyd C. Irland

Maine History

Complementing the qualitative account of forestry's impact provided by Geoffrey Carpenter, Lloyd Irland gives us a broad statistical overview of the industry, its changing economic fortunes, and its impact on the environment of the north woods. The data, while not always precise, reveal the terms upon which the state's decision-makers historically viewed the forest and its future. Mr. Irland is private forestry consultant in Winthrop, Maine, who has written widely on New England forestry topics, including Wildlands and Woodlots: The Story Of New England's Forests (1982).

Deforestation In Nineteenth-Century Maine: The Record Of Henry David Thoreau, Geoffrey Paul Carpenter

Maine History

Thoreau’s Maine Woods, a record of three trips made between 1846 and 1857, offers a combination of literary metaphor and precise botanical and topographical observation. Comparing Thoreau’s journals with recent advances in forest ecology, author Geoffrey Paul Carpenter reveals a detailed picture of the various ways in which logging activity changed the forests, lakes, and rivers of Maine. Carpenter demonstrates that a precise understanding of forest history depends not only on traditional statistical sources, but also on the subjective personal testimony found in the literary record.

Randomly Amplified Polymorphic Dna Analysis (Rapd) Of Artemisia Subgenus Tridentatae Species And Hybrids, E. Durant Mcarthur, Joann Mudge, Renée Van Buren, W. Ralph Andersen, Stewart C. Sanderson, David G. Babbel

Great Basin Naturalist

Species of Artemisia (subgenus Tridentatae) dominate much of western North America. The genetic variation that allows this broad ecological adaptation is facilitated by hybridization and polyploidization. Three separate studies were performed in this group using randomly amplified polymorphic DNA (RAPD). Fifty-seven 10-mer primers generated nearly 400 markers from genomic DNA obtained from leaf tissue. These studies were (1) a measure of the variability of plants within and between populations and between subspecies using 5 A. tridentata ssp. wyomingensis populations, 2 A. cana ssp. cana populations, and 1 A. cana ssp. viscidula population; (2) an examination of the hypothesis that …

Shifting Paradigms In Island Biology, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

The ease of travel by jet aircraft has opened up island areas not only for study but also for introduction of weeds, pests, and pathogens. We are at a critical juncture in the study of island organisms, which have become more accessible at the same time that they are vanishing. With the urgency for study of island organisms, we have many new tools, especially molecular ones, which have validated the existence of long-distance dispersal in unexpected ways. These tools, together with the ease of staying for longer periods on islands, have permitted us to understand many aspects of evolutionary adaptation …

Plant Conservation In The Juan Fernandez Archipelago, Chile, Tod F. Stuessy, Ulf Swenson, Daniel J. Crawford, Gregory Anderson, Mario Silva O.

Aliso: A Journal of Systematic and Floristic Botany

Oceanic archipelagos often hold very specialized floras with high degrees of endemism. These floras are frequently highly vulnerable to disturbance by natural causes and human intervention. The Juan Fernandez Islands (Chile) in the Pacific Ocean are a small archipelago of only three islands. Since discovery in 1574 by Juan Fernandez, human activities have altered floristic composition and survival circumstances of the endemic species. In this paper we document past and present means of disturbance, both anthropogenic and natural, which have influenced the native vegetation. The most destructive past activities have been logging and .introduction of animals and plants, both deliberately …
