Turbulent transfer in a deciduous forest
Tree Physiology, 1989Carbon dioxide, water vapor and other passive scalars are physically transferred between a plant canopy and the atmosphere by turbulence. Intense and intermittent sweep and ejection events transfer most of the mass. Although the capacity for turbulence to transfer material is high, mass transfer is coupled to the diffusive source or sink strength of ...

The deciduous forests occupy a very conspicuous portion of Europe, practically from latitude 40°N (Puglia, Albania) to 60°N (Scandinavia). They gradually grade through the intermediary of the mixed forests (Mischwald) into coniferous forests or taiga, so that their extension in the sense of longitude is from 10°W to 45°E.

The Deciduous Forest – Boreal Forest Ecotone
Geography Compass, 2010Abstract Ecotones have been subject to significant attention over the past 25 years as a consensus emerged that they might be uniquely sensitive to the effects of climate change. Most ecotone field studies and modeling efforts have focused on transitions between forest and non‐forest biomes (e.g. boreal forest to Arctic tundra, forest

The temperate deciduous forests
1988The deciduous forests of the Northern Hemisphere have been profoundly changed by long-established and repeated clearance for settlement and agriculture, even in relatively recently settled North America, so that only remnants remain from which to piece together their original character.

Ecology, 1938
Confusion results from lack of uniformity in the recognition of, and designation of climax associations of the deciduous forest formation. Their areal limits are little more than conjectural; no two maps agree. Even the most generalized accounts are fundamentally different.

The Epidemiology of Forest Decline in Eastern Deciduous Forests
Northeastern Naturalist, 1998Forest decline is viewed here as a subtle change that develops slowly and is difficult to distinguish from natural variation. This paper focuses on the approaches and data needed to understand causes of decline in complex systems. The challenge is to balance apparent explanations derived from parts of systems (reductionist view) against understanding ...

Termophilous deciduous forests in Southeastern Europe.
Plant biosystems, 2007The work focuses on the vegetation of the order Quercetalia pubescentis in Southeastern Europe. In the region, the alliances such as Fraxino orni-Ostryion, Carpinion orientalis, Syringo-Carpinion, Quercion confertae, Quercion petraeae-cerris, Quercion pubescenti-sessiliflorae and Aceri tatarici-Quercion have been established.

Plant Ecology, 2000
In this study, the first comprehensive multivariate statistical analysis of Danish native forest vegetation, based on 1768 sample plots, is presented. Data were composed of data from literature sources and newly collected data. A series of cluster analyses resulted in 24 forest community types, grouped in beech (Fagus sylvatica), oak (Quercus robur-Q ...
