Tree mortality in the Black Forest on the rise -- climate change a key driver      (via sciencedaily.com)     Original source 

Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.

Biodiversity protects against invasions of non-native tree species      (via sciencedaily.com) 

Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.

Hundreds of Andean bird species at risk due to deforestation: New research shows how to protect them      (via sciencedaily.com)     Original source 

Birds native to the tropical Andes are threatened by increasing agricultural development in the region. A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.

Magnonic computing: Faster spin waves could make novel computing systems possible      (via sciencedaily.com) 

Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date. Scientists have now discovered a significant new method: When the intensity is increased, the spin waves become shorter and faster -- another step towards magnon computing.
