How the Suez Canal will continue to change Mediterranean Sea - 0 views
-
Since the opening of the Suez Canal, the renowned waterway connecting the Red Sea to the Mediterranean Sea, its environmental impact has been a matter of concern, with the arrival of nonindigenous species from other regions. Since the official inauguration 150 years ago, the number of species that have arrived through the canal — known as Lessepsian or Erythrean species — is estimated to exceed 400, according to different studies. This is a substantial migration that some observers warn is causing the most significant biogeographic change currently underway worldwide.

“This has caused a substantial change in the traffic [food] webs of the Eastern Mediterranean, and such kind of life chain change has not been observed anywhere else in the world.”

Even if the introduction of Erythrean species started as soon as the canal opened, only a few established in the Mediterranean back then. It has only been in the last decades that the process has skyrocketed, and the number of alien species in the Mediterranean — not only Lessepsian — more than doubled between 1970 and 2015, bringing a new sense of urgency.
