A new study by UCLA scientists has indicated that fluctuations in climate can drastically affect the habitability of marine ecosystems.
The UCLA research team, which was led by assistant professor of atmospheric and oceanic sciences Curtis Deutsch, used a specialized computer simulation to demonstrate for the first time that the size of low-oxygen zones created by respiring bacteria is extremely sensitive to changes in depth caused by oscillations in climate. These oxygen-depleted regions, which expand or contract depending on their depth, pose a distinct threat to marine life.
“The growth of low-oxygen regions is cause for concern because of the detrimental effects on marine populations -- entire ecosystems can die off when marine life cannot escape the low-oxygen water,” said Deutsch.
It affects the total Nature, adversely!
