Stability of boreal forest stands during recent climate change: evidence from Landsat satellite imagery
Aim To detect possible expansion of boreal forest stands in response to recent warming. Previous modelling studies have concluded that major shifts in vegetation patterns, including changes in boreal forest extent, could arise during the next two centuries under global warming scenarios. However, ®eld investigations of tree stands at ecotones have so far revealed little indication of stand resp...
متن کاملChanges in fire regime break the legacy lock on successional trajectories in Alaskan boreal forest
Predicting plant community responses to changing environmental conditions is a key element of forecasting and mitigating the effects of global change. Disturbance can play an important role in these dynamics, by initiating cycles of secondary succession and generating opportunities for communities of long-lived organisms to reorganize in alternative configurations. This study used landscape-sca...
متن کاملFine-root dynamics in mixed boreal conifer – broad-leafed forest stands at different successional stages after fire
Fine-root (diameter ≤ 10 mm) standing biomass, length, distribution, production, and decomposition were studied in mixed conifer – broad-leafed forest stands 48, 122, and 232 years after fire on clay soils in the southern boreal forest of Quebec. A combination of ingrowth bags, soil cores, and root litter bags was used. Forest composition changed from trembling aspen(Populus tremuloides Michx.)...
متن کاملForest productivity decline caused by successional paludification of boreal soils.
Long-term forest productivity decline in boreal forests has been extensively studied in the last decades, yet its causes are still unclear. Soil conditions associated with soil organic matter accumulation are thought to be responsible for site productivity decline. The objectives of this study were to determine if paludification of boreal soils resulted in reduced forest productivity, and to id...
متن کاملWind-throw mortality in the southern boreal forest: effects of species, diameter and stand age
1. Patterns of tree mortality as influenced by species, diameter and stand age were assessed across a gradient in wind disturbance intensity in a southern boreal forest in Minnesota, USA. Few previous studies have addressed how wind impacts boreal forests where fire was historically the dominant type of disturbance. 2. We surveyed 29 334 trees of nine species within a 236 000 ha blowdown in the...
