Ancient long-lived pioneer trees store majority of carbon in tropical forests

Science
April 10 (UPI) -- Trees that grow fast, live long and reproduce slowly, known as long-lived pioneers, store the majority of carbon found in tropical forests. Scientists arrived at their discovery after analyzing the different development strategies used by various tree species. "In an earlier study we found that trees pursue different strategies during their development, and those strategies can be classified according to two independent criteria," lead study author Nadja RĂ¼ger, a scientist with the German Center for Integrative Biodiversity Research, told UPI. Some tree species, scientists found, grow fast and die young. Other species grow slow and reach old age. Different tree species also achieve different statures. Fertility also influences a trees' development pattern. Some trees g

A third of tropical African plants face extinction

Science
A third of tropical African plants are on the path to extinction, according to a new assessment.Much of western Africa, Ethiopia, and parts of Tanzania and the Democratic Republic of the Congo are the hardest hit regions, standing to lose more than 40% of their richness of plants. Species at risk include trees, shrubs, herbs and woody vines.Threats include deforestation, population growth and climate change, the scientists said."Biodiversity provides countless benefits to humans and losing diversity jeopardises our future," said lead researcher Dr Thomas Couvreur of the French National Institute for Sustainable Development. Loss of biodiversity will be particularly problematic in tropical Africa, "a region of incredible diversity...
