Vines strangle carbon storage in tropical forests

Tropical forests account for a third of the total carbon fixed by photosynthesis. Lianas’ increasing abundance may be driven by changing climate, increased disturbance or by more severe seasonal drought. By reducing the ability of tropical forests to accumulate and store carbon released through burning fossil fuels, lianas could cause a positive feedback loop, accelerating climate change. “This study has […]

Could we talk with whales?

Human-like sounds made by a captive beluga whale suggest that cetaceans could learn to mimic our voices, and perhaps even converse with us. Researchers at the National Marine Mammal Foundation first noticed in the 1980s that one of their whales was attempting to copy the speech patterns of his handlers and they began recording his human-like vocalizations. Recently, they analyzed […]
