Plants emit odours for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures.
New research into the causes of the devastating global biodiversity crisis has found that the conversion of natural forests and grasslands to intensive agriculture and livestock is the biggest cause
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.
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.
Preventing the re-clearing of second-growth forests is a major challenge for restoration efforts in tropical regions, according to a new study led by international researchers. The study found that a third of regenerating areas in the Brazilian Atlantic Forest were cut down again, most after just 4 to 8 years of regeneration.
