Up to half of plant and animal species in the world’s most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked.
The Amazon, Miombo Woodlands in Southern Africa, and south-west Australia are among the most affected places in the world, according to new research.
Traffic jams are the curse of the commute, the scourge of the school run and the bane of Bank Holidays. But gridlocked motorists and students of traffic flow may soon be relieved and enlightened thanks to new research into plants.
It has emerged that plants have it sorted when it comes to going with the flow and avoiding frustrating congestion. These fascinating results come from a joint study by the John Innes Centre, Norwich, and the University of Tokyo, Japan.
Why is a banana leaf a million times bigger than a common heather leaf? Why are leaves generally much larger in tropical jungles than in temperate forests and deserts? The textbooks say it’s a balance between water availability and overheating.
There are about 400,000 species of plants in the world. Humans use approximately 10–15% of them to cover our basic needs, such as food, medicine and shelter, as well as other needs, such as recreation, art, and craft. But why and how have humans selected only a small fraction of all plants to utilize? A new study published in today’s Nature Plants sheds new light on these questions by investigating how people use palms in South America. The overall conclusion is that people are very selective when it comes to plants used to cover basic needs, but less so when it comes to using plants for needs with no physiological underpinnings.
