Mixed-Silver Maple Forests Of The Upper Mississippi River Floodplain: Variations In Composition, Structure, And Growth Along Environmental Gradients
Floodplain forests of the Upper Mississippi River are characterized by complex interactions between biota and the physical environment, specifically aspects of hydrology. The role of environmental variation in overstory composition, structure, and growth is not well documented. Goals of this study …

Episodic Recruitment and Climate Analysis of Ponderosa Pine on the Palmer Divide, Eastern Colorado
<p>Previous recruitment studies on populations of ponderosa pine (<em>Pinus ponderosa</em> P. & C. Lawson) in Colorado have been limited to the western mountains and the Front Range. In this research I used tree-ring data to reconstruct recruitment for ponderosa pine near the eastern limits of its …

A Denroecological Analysis of Disturbance of Remnant Pinus Palustris, Southeastern Virginia
Pinus palustris Miller (longleaf pine), in Virginia, is at the northernmost extent of its range. During presettlement times, this species occurred throughout the Piedmont and Coastal Plain of Virginia in pure and mixed stands, covering 607,000 hectares. This forest type has since been reduced to 81 …

Dendroklimatologische und dendroökologische Untersuchungen des Zuwachsverhaltens von Buche und Fichte in naturnahen Mischwäldern
Vor dem Hintergrund sich verändernder Umweltbedingungen durch den allgegenwärtigen Klimawandel wächst das Interesse an Vorhersagen zur zukünftigen Waldentwicklung. Der prognostizierten Häufung von Witterungsextremen wird ein wesentlicher Einfluss auf das Wachstum und die Vitalität der Waldbaumarten …

Effects of Biotic Interactions on Climate-Growth Relationships of Douglas-Fir and Ponderosa Pine
<p>Plant processes depend on the interplay between intrinsic characteristics (e.g., photosynthetic capacity) and external variables, such as light, temperature and water availability. However, these factors are often tightly interconnected and vary significantly among species with different life …

Potential of temporal and spatial analysis techniques as tools for exploring changes in forest site productivity and following environmental interactions : Finnish-German comparative study
The main target of this study is the detection of possible changes in forest site productivity and interaction with changes in the environmental conditions by the use of temporal and spatial analysis techniques. Height and radial increments of Norway spruce (Picea abies L. Karst) and Scots pine …
