An aggressive new strain of sudden oak death, a disease that's killed millions of trees, has turned up in Oregon, posing a threat to timber production. Scientists are using a 3D model called Tangible Landscape to help stakeholders work together to find ways to contain the disease's spread.
The study shows the advantages of herbicide spraying and intensive fertilization in reforestation programs to mitigate the effects of climate change.
Tropical forests are being deforested at an alarming rate to make way for agriculture; the good news is that they can regrow naturally when the fields are abandoned. An international research team including participation from the University of Göttingen found that regenerating wet and dry forests actually show opposite pathways. This implies a fundamental change in our understanding of how tropical forests change, with consequences for forest restoration and biodiversity. Results are in Nature Ecology and Evolution.
As spring arrives in the northern hemisphere, many people are cursing ragweed, a primary culprit in seasonal allergies. But scientists might have discovered a promising new use for some substances produced by the pesky weed. In ACS' Journal of Natural Products, researchers have identified and characterized ragweed compounds that could help nerve cells survive in the presence of Alzheimer's disease (AD) peptides.
Rainfall from the Asian summer monsoon has been decreasing over the past 80 years, a decline unprecedented in the last 448 years, according to a new study in the AGU journal Geophysical Research Letters.
Data collected from over 1 million forest plots reveals patterns of where plant roots form symbiotic relationships with fungi and bacteria.
Removing invasive shrubs to restore native forest habitat brings a surprising result, according to Penn State researchers, who say desired native understory plants display an unexpected ability and vigor to recolonize open spots.
Defaunation -- the loss of species or decline of animal populations -- is reaching even the most remote and pristine tropical forests. A new study publishing May 14, 2019 in the open-access journal PLOS Biology, led by Ana Benítez-López from Radboud University, the Netherlands, predicts that even where deforestation has not been detected in the tropcis, hunting is reducing populations of large mammals by 40% on average, largely due to increased human accessibility to these remote areas.
A group of researchers from the University of Helsinki has found a ground breaking new method to facilitate the observation of photosynthetic dynamics in vegetation. This finding brings us one step closer to remote sensing of terrestrial carbon sinks and vegetation health.
Wildfires can have dramatic impacts on Western landscapes and communities, but human values determine whether the changes caused by fire are desired or dreaded. This is the simple - but often overlooked - message from a collaborative team of 23 researchers led by University of Montana faculty in a study published in the May issue of the journal BioScience.
