A research team investigated the impact of extreme fires on previously intact carbon stores by studying the soil and vegetation of the boreal forest and how they changed after a record-setting fire season in the Northwest Territories in 2014. They collected 200 soil samples and used radiocarbon dating to estimate the carbon age. They found combustion of legacy carbon in nearly half of the samples taken from young forests (less than 60 years old).
By analysing 138 experiments, researchers have mapped the potential of today's plants and trees to store extra carbon by the end of the century.
Burning invasive western juniper increases the time -- post-fire -- that native mountain sagebrush will remain the dominant woody vegetation in the plant community by at least 44% compared to cutting juniper back, according to a new study in Ecology and Evolution by Agricultural Research Service (ARS) scientists and their collaborators.
Soil bedding increases microbial and termite decomposition activity
Moose are picky eaters, and that's a good thing for their ecosystems.
Deforestation in Colombia has been linked to armed conflict and forests' proximity to coca crops, the plant from which cocaine is derived. A University of Queensland-led study found that conflict between illegal groups and the governmental military forces, proximity to coca plantations, mining concessions, oil wells and roads were all associated with increased deforestation.
Forests in the eastern United States that are structurally complex -- meaning the arrangement of vegetation is highly varied -- sequester more carbon, according to a new study led by researchers at Virginia Commonwealth University. The study demonstrates for the first time that a forest's structural complexity is a better predictor of carbon sequestration potential than tree species diversity. The discovery may hold implications for the mitigation of climate change.
Largescale 'disturbances', including fires, harvesting, windstorms and insect outbreaks, which kill large patches of forest, are responsible for more than a tenth of tree death worldwide, according to new research at the University of Birmingham.
The use of remote sensing equipment for data collection has revolutionized biological data collection in the field, but researchers still need tools to help analyze the data. RadialPheno supports the study of phenology -- the timing of developmental events like flowering and fruiting -- by providing a visualization system that identifies temporal patterns. Such tools are urgently needed to understand how climate change is affecting ecosystems by altering the timing of phenological events and ecological interactions.
How much carbon dioxide can tropical rainforests absorb? Investigations by an international team of researchers with significant involvement from the Technical University of Munich (TUM) indicate that the absorption capacity is severely limited by the phosphorus content of the soil.
