Plants. Know what kind of plant is most vulnerable to climate change
A new study suggests that non-native plants may outweigh native plants because of climate change. A study by researchers at the Institute of Environmental Flexibility at the University of Indiana found that high temperatures affect local flowering plants more than non-local ones, which may change the appearance of local plants in the region.
"The timing of the plant life cycle is vital to the survival of species, when the plant flowers determine whether they will be vaccinated," said Jane Lau, a co-researcher in biology at the College of Arts and Sciences at Bloomington and a member of the Institute of Environmental Resistance. By bees or other insects and how much time you will need to produce seeds. "
"Our data make me worry that we will have a world full of weeds in our future because of the effects of climate change," she said.
The results of the researchers suggest that non-native plant species may be better at converting their time of prosperity compared to local plant species, and these differences are believed to affect the success of either species at present and in warmer environments in the future.
To test this hypothesis, Lao and her students simulated global warming in fields planted with 45 local and non-local species. Some areas were heated by infrared heaters, while others were not.
The Lao laboratory surveyed all plants to determine when they were first bloomed and long-lived. The researchers found that non-native species thrived more than 11 days ago on average, while local species did not and did not specify flowering times when their temperature rose.
The results indicate important differences in how native and non-indigenous plant species respond to climate change. Other studies have shown that species that failed to change their flowering times during the last century were more likely to be depleted or extinct, so local species may be more vulnerable to change. Climate of non-indigenous species.
