Drought-induced shift of a forest-woodland ecotone: rapid landscape response to climate variation.
In coming decades, global climate changes are expected to produce large shifts in vegetation distributions at unprecedented rates. These shifts are expected to be most rapid and extreme at ecotones, the boundaries between ecosystems, particularly those in semiarid landscapes. However, current models do not adequately provide for such rapid effects-particularly those caused by mortality-largely ...
متن کاملHolocene paleoenvironments in southeastern Minnesota ^ chasing the prairie-forest ecotone
This paper uses a multi-proxy approach involving pollen, plant macrofossils, speleothem isotopes, and alluvial history of streams to reconstruct the history of prairie expansion and contraction along the prairie-forest border of southeastern Minnesota, USA. Early Holocene forests were replaced by prairie along this border, but eastward expansion of prairie stalled for 2000 yr when the prairie-f...

متن کاملLivelihood dependency on woodland resources in southern Zagros, Iran
This study aims to investigate the relationships between people?s livelihoods and the woodland resources of the Ganaveh watershed in southern Zagros, Iran, as a basis for suggestions of strategies for sustainable management of the woodland resources and improvement of the livelihoods of people in the community. Household data were collected through interviews with heads of households and member...
متن کاملClimate change and fire effects on a prairie–woodland ecotone: projecting species range shifts with a dynamic global vegetation model
Large shifts in species ranges have been predicted under future climate scenarios based primarily on niche-based species distribution models. However, the mechanisms that would cause such shifts are uncertain. Natural and anthropogenic fires have shaped the distributions of many plant species, but their effects have seldom been included in future projections of species ranges. Here, we examine ...
