Progress In Soil Organic Matter Research, Vineet Yadav, George Malanson

George P Malanson

Retention and sequestration of soil organic matter is extremely important for the maintenance of soil structure, agricultural productivity and carbon sequestration. Research in soil organic matter has advanced on many fronts in the last half century. During this time understanding of the factors governing plant litter decomposition has increased considerably resulting in the formulation of process and organism-based models. Remote sensing has been shown to be useful for quickly monitoring stocks of soil organic carbon in the topsoil although much remains to be done to establish its efficacy. Fluxes of soil organic matter in the changing climatic scenarios have been …

Lithologic, Structural, And Geomorphic Controls On Ribbon Forest Patterns In A Glaciated Mountain Environment, David Butler, George Malanson, Matthew Bekker, Lynn Resler

George P Malanson

So-called "ribbon forests" have been attributed to snowdrift patterns and fire history without reference to geomorphology [Vegetatio 19 (1969) 192]. This paper illustrates how site conditions of geomorphology and geology explain the origin of ribbon forests. In Glacier National Park, MT (USA), regional tectonic uplift associated with the Laramide Orogeny produced structural features that amplify lithologic differences. Pleistocene glaciation scoured deeply along the strike of bedding planes, highlighting this pattern and in some cases producing fine-scale parallel finger lakes between forested ribbon strips. Twelve ribbon forest sites on both sides of the Continental Divide were closely studied on stereoscopic aerial …

Sedimentation Rates And Patterns In Beaver Ponds In A Mountain Environment, David Butler, George Malanson

George P Malanson

Sediment depth was measured at several sites within each of eight beaver ponds in Glacier National Park, Montana, and sediment samples were collected from five of these ponds. Accumulation rates of sediments far exceeded published rates from boreal forest landscapes in eastern and central North America. Pond area strongly predicts volume of sedimentation. Textural differences illustrated spatial variations associated with position in a pond and along a pond sequence. Organic matter content was significantly higher in older ponds, and has ramifications for the development of the benthos and the long-term storage of matter in ponds. The role of beavers as …

Precipitation And Temperature Estimation Error At Alpine Treeline Ecotones Using The Mountain Climate Simulator Model (Mt-Clim), Darren Grafius, George Malanson

George P Malanson

In order to improve modeling of alpine treeline responses to climate change, estimations of snowfall at treeline sites are needed. The MT-CLIM climate model was evaluated for this purpose by extrapolating precipitation and temperature from standard weather stations at lower elevations to 30 alpine SNOTEL study sites across the western United States. Quantification of the topography between the base stations and the SNOTEL sites was used in inverse distance weighting and compared to straight-line weighting. The predicted temperature and precipitation under different weighting methods were compared to observed data over three months during the winter of 2006-2007. The errors were …

Modeling Interactive Effects Of Climate Change, Air Pollution, And Fire On A California Shrubland, George Malanson, Walter Westman

George P Malanson

A computer simulation model (FINICS) was used to project the interactive effects of CO2-induced climate change on a drought-deciduous shrubland. FINICS simulates the competitive relations of five dominant shrub species of Californian coastal sage scrub, based on their aboveground growth and reproductive behavior. The model was used to simulate the separate and combined effects of altered precipitation, temperature, ambient ozone levels, and fuel loads and fire intensity, on species composition. Both growth chamber and field data were used to parameterize the model. Projections show that changes attributed to climate variation alone were markedly accentuated when the indirect effects of climate …

Ecological Response To Global Climatic Change, George Malanson, D. Butler, S. Walsh

George P Malanson

This volume, celebrating the 100th anniversary of the Association of American Geographers, is dedicated to the idea that geographers can make substantive differences to the lives of people and to the well being of the planet that gives the discipline its name. WorldMinds provides broad exposure to a geography that is engaged with discovery, interpretation, and problem solving. Its 100 succinct chapters demonstrate the theories, methods, and data used by geographers, and exemplify the conceptual and topical richness of contemporary geography. The 150 contributing authors and co-authors address the challenges posed by issues such as globalization, regional and ethnic conflict, …

Linear Vegetation Patterns In Subalpine Forests., Matthew Bekker, George Malanson

George P Malanson

The study of vegetation pattern can yield valuable insight into interactions between vegetation and the environment. These interactions often involve positive feedback wherein biological, atmospheric, or geomorphic processes are amplified, resulting in abrupt vegetation boundaries, rapid changes, and/or thresholds in system behavior. Many relatively linear vegetation patterns have been described in subalpine forests, including "ribbon forests," "krummholz islands," "hedges," "fingers," and "fir waves." In this paper I review research on these phenomena, including an assessment of their distribution, the combinations of environment and species that produce them, and the implications of their existence for using vegetation boundaries as indicators of …

The Fractal Shape Of Riparian Forest Patches, K. Rex, George Malanson

George P Malanson

Remnant patches of a forest corridor were examined along the Iowa and Cedar Rivers, Iowa. A fractal dimension was found for these patches which was incorporated with the perimeter:area ratio in an index of shape. This index was then regressed on 5 hydrogeomorphic variables hypothesized to represent processes which might control patch dimensions, plus a variable to represent human impact. The hydrogeomorphic variables were derived from topographic maps; the impact variable used was the proportion of perimeter that was occupied by a road, railroad, transmission line, urban or other built area, or a straight line judged to be agricultural. Three …

Hugh Of St Victor (1096–1141) And Anglo-French Cartography, Daniel Terkla

Daniel Terkla

Recent research in England and France on twelfth- and thirteenth-century cartography posits Hugh of St Victor as an important source for ideas incorporated in maps of the period. P. D. A. Harvey and Patrick Gautier Dalché have noted Hugh’s influence, and Peter Barber has described a ‘third-stream’ of map making flowing from Hugh’s concepts of mapping through the Munich Isidore map (c.1130) and into a group of important Anglo-French mappaemundi. This article shows how Hugh’s theography—his theological cartography—reached England from the Royal Abbey and School of St Victor in Paris. To do this I outline Hugh’s image-based teaching and major …
