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.
When wildfires burn up forests, they don't just damage the trees. They destroy a key part of the global carbon cycle. Restoring those trees as quickly as possible could tip the scale in favor of mitigating severe climate change. Lisa A. McCauley explains how quick action to thin out vegetation will actually increase carbon storage in forests by the end of this century.
CABI's expert scientists in the field of ecosystems management and invasion ecology have presented new guidance on ways to help protect the world's trees and forests from harmful pests and diseases such as the box tree moth and ash dieback. Researchers suggest that a number of important factors should be considered when monitoring for non-native pests that can pose a serious threat to forest resources and have significant negative economic, biodiversity and livelihood impacts.
Strawberry poison frogs live in Costa Rican forests that are being cut down for farmland. The deforested pastures are hotter and sunnier, so scientists wanted to see if the frogs had adapted to withstand the heat. They learned that the frogs from pastures had adapted to seek out warmer temperatures than frogs from forests. The maximum temperature they can stand didn't change, though -- so if global temperatures rise too much, the frogs are in trouble.
