Spatial distributions of understory light along the grassland/forest continuum: effects of cover, height, and spatial pattern of tree canopies
The understory light environment is a key determinant of vegetation pattern and ecosystem processes, and varies spatially perhaps more than any resource used by plants. Understory light varies along gradients of vegetation structure that range from grassland with no woody canopy cover to forest with nearly complete woody canopy cover. Spatial variability in understory light is largely determine...
متن کاملThe grassland–forest continuum: trends in ecosystem properties for woody plant mosaics?
www.frontiersinecology.org © The Ecological Society of America F an airplane, we often look out the window and survey the landscape as we begin our final descent. As we get closer to the ground, our focus changes from an initial broad survey of the topography to an increasingly detailed picture of vegetation patterns. Perhaps the first thing we notice is the extent to which the land is covered ...
متن کاملNear-ground solar radiation along the grassland–forest continuum: Tall-tree canopy architecture
Solar radiation directly and indirectly drives a variety of ecosystem processes. Our aim was to evaluate how tree canopy architecture affects near-ground, incoming solar radiation along gradients of increasing tree cover, referred to as the grassland–forest continuum. We evaluated a common type of canopy architecture: tall trees that generally have their lowest level of foliage high above, rath...

In this study we evaluate the effects of different types on soil Physical and chemical Properties and plant species biodiversity in the hyrcanian forests of Iran. For this porpuse 33 sample plots were established in 5 vegetation types consist of pure beech (Fagus orientalis), Ash plantation (fraxinus excelsior), spruce plantation (Picea abies), mixed forest and degraded forest. In each ...
متن کاملAeolian process effects on vegetation communities in an arid grassland ecosystem
Many arid grassland communities are changing from grass dominance to shrub dominance, but the mechanisms involved in this conversion process are not completely understood. Aeolian processes likely contribute to this conversion from grassland to shrubland. The purpose of this research is to provide information regarding how vegetation changes occur in an arid grassland as a result of aeolian sed...
