متن کاملThermokarst rates intensify due to climate change and forest fragmentation in an Alaskan boreal forest lowland.
Lowland boreal forest ecosystems in Alaska are dominated by wetlands comprised of a complex mosaic of fens, collapse-scar bogs, low shrub/scrub, and forests growing on elevated ice-rich permafrost soils. Thermokarst has affected the lowlands of the Tanana Flats in central Alaska for centuries, as thawing permafrost collapses forests that transition to wetlands. Located within the discontinuous ...
متن کاملForest structure and species composition along a successional gradient of Lowland Atlantic Forest in Southern Brazil
The Lowland Forest is one of the most disturbed and fragile ecosystems in the Atlantic Forest biome, yet little is known regarding its successional trajectory and resilience. We evaluated changes in species assemblages and forest structure of the canopy and understory along a successional gradient (young 21-yrs old forest, immature 34-yrs old forest and late successional 59-yrs old forest) aimi...
متن کاملSpecies Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)
Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...
متن کاملModelling atmospheric OH-reactivity in a boreal forest ecosystem
We have modelled the total atmospheric OHreactivity in a boreal forest and investigated the individual contributions from gas phase inorganic species, isoprene, monoterpenes, and methane along with other important VOCs. Daily and seasonal variation in OH-reactivity for the year 2008 was examined as well as the vertical OHreactivity profile. We have used SOSA; a one dimensional vertical chemistr...
