Structural and functional features of the leaf assimilatory apparatus in plants of a forest-steppe oakwood. I. Leaf plastid apparatus in plants of various forest strata
Stickstoff als Okofaktor naturnaher Berg-Fichtenwälder. (Nitrogen as an ecofactor in close-to-nature mountainous spruce forests)
Differential patterns of nitrogen content of F+H-layer in 11 forms of mountainous spruce forest in the area of the Harz moutains and the Sudetes are analysed. Total nitrogen, hydrolysable nitrogen and lumb amino acid content of the organic soil
of mountainous spruce forests do not differ at all or only slightly with regard to the relative proportions of the main kinds of nitrogen-acid-hydrolysable, water-soluble and residual nitrogen-while the absolute forms show a manyfold differential pattern
Zur Beeinflussung von Wachstum-und Zuwachsprozessen in Wäldern durch Immissionen. (The impact of immission on processes of forest growth and increment)
An investigation of influence of SO and lime dust on the current annual increment and timber supply in wood stocks in the state-owned forest enterprise (STFB) Dübener Heide revealed significant correlations between the development of wood stocks

-tundra, and this by open Picea glauca forest similar to present vegetation around the lake. Sites on HCM show two basic stratigraphies. Triangle Lake reflects vegetational succession from Salix-Shepherdia canadensis scrub similar to that on K-III today
, through open Picea woodland of K-IV type, to closed Picea forests of K-V and HCM. Heart Lake and Cotton Pond reflect vegetational development following melting of ice underlying the spruce forests of HCM. These two types are summarized by positioning
Testing a simulation model for reconstruction of prehistoric forest-stand dynamics
Three characteristics of the output of a forest-stand simulation model were matched to pollen records of actual vegetation in central Tennessee. Temporal shifts of individual pollen taxon frequencies were compared to shifts of individual plant
toward the spruce forest. These trends in soil development with time are strikingly similar to those reported from Glacier Bay, except that the changes in soil properties appear to be delayed by 50100 yr at the Klutlan terminus. Low temperatures, a short
subsidence can convert humic-water lakes surrounded by second-generation spruce forests into turbid-water lakes with unstable, slumping margins. A detailed paleolimnological study of two lakes, one on the unglaciated upland and another in an outwash channel
the western edge of the eastern deciduous forest: S. floridanus and S. niger decrease and S. carolinensis increases in size. Archeological samples of S. carolinensis from Rodgers Shelter (23BE125), Benton County, Missouri, and Graham Cave (23MT2), Montgomery
yr old) have a multiple-generation spruce forest, yet melting of buried ice still locally forms young lakes. Cores of organic sediment from the oldest lakes contain a stratigraphic sequence of pollen, diatoms, and cladocerans that record the early
