Plants are flowering faster than scientists predicted (预测) in reaction to climate change, which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns, scientists say.
Increased carbon dioxide (CO2) in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’reaction to climate change is a major challenge in ecology, ” said the researchers of several U. S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1, 634 species. It found that some experiments had underestimated (低估) the speed of flowering by 8. 5 times and leafing by 4 times.
“Across all species, the experiments under- predicted the speed of the advance—for both leafing and flowering—that results from temperature increases, ”the study said.
