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 …

Reinterpretation Of Relations Between Vegetation Removal And Water Yield, George P. Malanson, D. P. Post

George P Malanson

While the relation between vegetation clearance and increasing streamflow appears to be strong for data aggregated among geographic regions, results are equivocal in local areas. Earlier data are re-analyzed to consider the role of hydroclimatology. While vegetation clearance increases absolute streamflow, the proportional change is not significant. Residuals of regressions of absolute and proportional change in streamflow on vegetation clearance are related to precipitation, with positive and negative slopes, respectively. A few outliers with high responses are important in creating a pattern, and hydroclimatology is a better predictor of change in streamflow than is vegetation clearance for aggregate data. With …

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 …

التنظيم المكاني للمجتمع الليبي المعاصر: حدود النمو الحضري, Mansour M. Elbabour

Mansour M Elbabour

Libya, which is well over 80% urban, is placed in the upper echelons of the most urbanized countries in the world as the majority of its citizens now live in urban areas of different sizes and functions. However, when rapid urban growth trends were examined more closely, serious problems come to the fore, depicting key challenges to the sustainability of both urban landscapes and elements of the natural environment. Specifically, unregulated urban growth and the proliferation of scattered housing in the urban fringe areas of many cities have resulted in land use conflicts and serious ecological problems.
