Rapid tree carbon stock recovery in managed Amazonian forests
While around 20% of the Amazonian forest has been cleared for pastures and agriculture, one fourth of the remaining forest is dedicated to wood production. Most of these production forests have been or will be selectively harvested for commercial timber, but recent studies show that even soon after logging, harvested stands retain much of their tree-biomass carbon and biodiversity. Comparing sp...
متن کاملMind the gap: how open were European primeval forests?
There are two competing hypotheses about the structure and dynamics of primeval forests in lowland Europe: the high-forest and the wood-pasture hypotheses, both of which influence current European forest conservation policies. In a recent study using pollen-analytical data from across lowland Europe, Mitchell provides support for rejecting the wood-pasture hypothesis. His study is important for...
متن کاملReconstructing the temperature degree of the warm seasons through Quercus persica tree rings in Zagros forests Dena region
Trees can record long-term effects of climate variables. Using dendroclimatology knowledge, we can reconstruct such variables especially for areas which have short-term climatic data. For this purpose, we reconstructed the temperature degree of the warm months (May-September) through annual rings width of Quercus persica and regression analysis of data obtained from stations on Dena region. Wit...
متن کاملHow Do Urban Forests Compare? Tree Diversity in Urban and Periurban Forests of the Southeastern US
There is a need to understand how anthropogenic influences affect urban and periurban forest diversity at the regional scale. This study aims to compare urban and periurban tree composition along a geographic gradient, and test hypotheses about species composition and ecological homogeneity. We paired urban forest (UF) data from eight cities across the southeastern US with periurban forest (PF)...
متن کاملHow ancient are ancient asexuals?
Ancient asexual animal groups, such as bdelloid rotifers and darwinuloid ostracods, are excellent model organisms to study the effects of long-term asexuality. However, the absolute length of time that these groups have been fully asexual is mostly ignored. In the case of the darwinuloid ostracods, the fossil record shows that sexual reproduction disappeared almost completely after the end of P...
