Trees shield weak species from climate change

Belgium: Forests with dense canopies create a microclimate that protects a variety of cold-adapted plant species from warming air temperatures, a study has shown. Researchers found plants that favoured cooler conditions fared better under dense canopies than in ones that were more open to the elements. They added that these conditions could be a “critical mechanism” in the conservation of forest plant diversity.
The findings appear in the Proceedings of the National Academy of Sciences. A team of international researchers, headed by scientists from Belgium, noted that previous studies had shown that “biological signals of recent global warming” had been increasing across an array of ecosystems.–BBC
