Repeated Fires Drive Long-Term Changes to Tree Communities, Reduce Their Population
Written by AZoCleantechFeb 26 2021
Several decades of data related to the effect of recurrent fires on ecosystems throughout the world have been analyzed by researchers from the University of Cambridge.

Published recently in the
Nature Ecology and Evolution journal, the findings of the study indicate that recurrent fires are inducing long term variations to tree communities and decreasing their population sizes.
Savannah ecosystems and regions with extreme dry or wet seasons were discovered to be the most sensitive to variations in fire frequency. In regions with moderate climate, trees tend to be more resistant. Recurrent fires do not damage those tree species much that have safety traits such as thicker bark.

Using Submarine Cables to Detect Earthquakes
Seismologists at Caltech working with optics experts at Google have developed a method to use existing underwater telecommunication cables to detect earthquakes. The technique could lead to improved earthquake and tsunami warning systems around the world.
A vast network of more than a million kilometers of fiber optic cable lies at the bottom of Earth’s oceans. In the 1980s, telecommunication companies and governments began laying these cables, each of which can span thousands of kilometers. Today, the global network is considered the backbone of international telecommunications.
Scientists have long sought a way to use those submerged cables to monitor seismicity. After all, more than 70 percent of the globe is covered by water, and it is extremely difficult and expensive to install, monitor, and run underwater seismometers to keep track of the earth’s movements beneath the seas. What would be ideal, researchers say, is
