Scientists have estimated the conservation status of nearly 1,900 palm species using artificial intelligence, and found more than 1,000 may be at risk of extinction.
Researchers have identified a new reason to protect mangrove forests: they’ve been quietly keeping carbon out of Earth’s atmosphere for the past 5,000 years.
A new study in Costa Rica reveals that restoring relatively narrow strips of riverfront forests could substantially improve regional water quality and carbon storage. The analysis, shows that such buffers tend to be most beneficial in steep, erosion-prone, and intensively fertilized landscapes – a finding that could inform similar efforts in other countries.
A team of environmental scientists has written a follow-up paper to their study published last year that warned that approximately one-third of tree species around the world are in danger of extinction. In this new paper, the group explains why the loss of so many tree species is so devastating and why attempts should be made to reverse such extinctions.
Agriculture drives more than 90 percent of tropical deforestation. Halting deforestation will require a step-change in approach and to be effective measures must address underlying and indirect roles of agriculture, says a new study.
Researchers have developed a novel value chain for production of textile and bio-fuel from fast-growing poplars. By applying sustainable catalysis on these poplars grown on marginal land in Nordic climates, the demand for cotton can be reduced. Consequently, considerable areas of productive agricultural land can be converted from cotton to food production.
Over the last century, emerging diseases have progressively been recognized by the scientific community as the main threat to forest ecosystems. With increasing international trade and globalization, the introduction of non-native species into new environments has exacerbated the problems of emerging pests and diseases worldwide. Additionally, other factors, such as climate change, further complicate matters by altering host-pathogen interactions, thus promoting the spread of diseases caused by native or non-native pathogens.
A new study shows that it took more than 10 millennia from when the first spruces returned to Sweden after the glacial stage of the last Ice Age until the species became widespread. This sluggish rate of initial dispersal has surprised the researchers, since the spruce might have had good prospects of expanding its range.
