Remote sensing techniques help treat and manage hollow forests
Oak tree decline detected by advanced remote sensing techniques
DNA duplication linked to the origin and evolution of pine trees and their relatives
GAINESVILLE, Fla. — Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added genetic baggage. All those extra genes are…
Epicentre of major Amazon droughts and fires saw 2.5 billion trees and vines killed
A major drought and forest fires in the Amazon rainforest killed billions of trees and plants and turned one of the world’s largest carbon sinks into one of its biggest polluters.
Ocean microbes team up brilliantly to gather food when it’s scarce
WOODS HOLE, Mass. – What’s a hungry marine microbe to do when the pickings are slim? It must capture nutrients – nitrogen, phosphorus, or iron – to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. And…
