Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits
Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. By cross-dating Swedish bog-pine ring-width (RW) chronologies with corresponding material from North-west Germany, three Swedish RW chronologies were assigned …

Tree-ring analysis and stem biomass estimation of limba (Terminalia superba Engl. & Diels) in the framework of sustainable forest management
… tropical forests. The lack of long-term data on tree growth, wood production and carbon stocks hampers the implementation of sustainable forest management and possible financing by Kyoto Protocol related tools like REDD+ and Clean Development Mechanisms. Africa is the continent with the lowest …

Episodic Recruitment and Climate Analysis of Ponderosa Pine on the Palmer Divide, Eastern Colorado
… and the Front Range. In this research I used tree-ring data to reconstruct recruitment for ponderosa pine near the eastern limits of its distribution at two sites on the Palmer Divide, Eastern Colorado, to determine the relative climate sensitivity of the two sites, and the extent to which …

Interactions between human industry and woodland ecology in the South Pennines
… of case study sites was combined with charcoal analysis from excavated burning platforms, palynology of soil cores, tree ring analysis and ecological survey. This was set within a historical context, particularly focusing on the regional industries of iron, leather and textiles, in order to …

Development of Urban Tree Growth Models Based on Site and Soil Characteristics
Trees provide numerous benefits crucial to urban environments, yet poor growing conditions often prevent trees from reaching their genetic potential for growth, longevity, and ecosystem function. To overcome these limitations, greater understanding of tree growth in the urban environment is needed. …

Mapping Ancient Baldcypress Forests for Conservation at Black River, North Carolina
… stands left untouched by extensive logging during the early 20th century. Uncut stands in the Southeast that survived centuries of disturbance following European settlement tended to be too senescent and non-commercial to justify logging. Remnant ancient baldcypress forests at Black River, …

Time and soil development on lateral moraines, Martin River Glacier, south-central Alaska
<p>During the summer of 1966, eighteen soil profiles on a series of 21 lateral moraines, were studied to ascertain the relationship of time to soil development. The moraines are located on Charlotte Ridge on the south margin of the Martin River Glacier in south-central Alaska. The elevation of the …

Wachstumsraten, Wachstumsmuster und Wachstumsstörungen tropischer Bäume: Analyse von Langzeiteffekten und kurzfristigen Störungen mit Hilfe von Jahrringstudien
… and ecology. In species that produce annual tree rings, tree-ring analysis allows the most precise estimate of these two parameters. The present study assessed the age and radial growth rate of three Hymenaea species inhabiting four of the six biomes found in Brazil. Out of these four biomes, …
