The waters of the Galapagos Islands are invaded by alien species that could threaten hundreds of native marine creatures.
- Alien sea creatures from around the world could endanger native life
- The area on ship hulls
- The study states that the effects are not yet known, but that invasive species had a negative impact on ecosystems in other parts of the world ,
Marine species that have invaded the waters around the Galapagos Islands off the coast of Ecuador could endanger the lives of indigenous peoples, warn experts ,
Field studies identified 48 new invasive species and five known non-native species off the coast of the South Pacific Islands.
These "extraterrestrial" species included worms, shells, crabs and sea-sprouts from other Pacific regions, as well as from afar – including the Mediterranean.
Scientists say the invading creatures from all over the world are hanging on ships before finally settling in their new environment and multiplying.
The effects on the ecosystems of the islands are not yet known, but the researchers say that they are likely to threaten hundreds of marine species of the islands in the region.

alien sea creatures has conquered the waters around the Galapagos Islands off the coast of Ecuador, which could jeopardize the native life in the sea. Field studies have found 48 new invasive species and five known non-native species. Here is the native marine iguana
Previous studies have shown that poisonous lionfish, a well-known invader, can capture other species of fish and kill coral reefs.
Tiny moss creatures such as Amathia verticillata resemble filthy, gelatinous noodles, up to three feet (1 meter) in length, when forming colonies and killing seaweed.
The area, a hotspot of biodiversity and World Heritage, has a number of invasive species on land, but little is known about those in the marine environment.
Seventeen of the invader species had previously been spotted in the waters, but were believed to be indigenous species.
The actual number of invasive species is likely to be much higher in the study as the surveys were conducted only in some habitats around two of the larger islands.
"According to our knowledge of similar studies, I would not be surprised if the number was twice that [as many]," team member Professor Jim Carlton of Willi Ams College of Massachusetts said the New Scientist.
Scientists testify that organisms settle on ships from all over the world and settle in their new environment. The effects on the ecosystems of the islands are not yet known, but they are likely to threaten hundreds of endemic marine animals in the islands
The study found that the impact of these alien species on the ecosystem is unknown.
It is likely to be negative, however, to assess the experience elsewhere and threaten the hundreds of endemic marine animals in the islands.
"What we do know is that some of these [invasive] species clearly had an impact in other parts of the world," said Professor Carlton.
The team warned that invasions, including soft corals, could quickly grow above local corals.
The Galapagos Marine Reserve is protected, but it will be difficult to stop more invaders, as it is difficult to search for tiny species of the hull of any boat.
WHAT ARE THE PROTECTION AREAS OF THE EARTH?
In 2010, the International Union for Nature Conservation established Earth's protected areas.
These were first described in 2008 as "clearly defined geographical area, recognized, dedicated and managed, described legal or other effective means to achieve the long-term conservation of nature with related ecosystem services and cultural values. "
The IUCN claims that the global network of protected areas stores at least 15 percent of terrestrial carbon.
There are now more than 202,000 areas around the world.
They were designed with three specific objectives in mind:
- Valuing and preserving biodiversity
- Managing the use of nature and sharing its benefits
- Using nature-based solutions to global challenges
In 2010, the International Union for Nature Conservation established and clearly defined nature reserves. There are now more than 202,000 territories around the world
