UN-Bericht zu Tiefsee-Schwämmen erschienen

Die UNEP hat einen neuen lesenswerten Bericht zu Tiefsee-Schwämmen erstellt, der die Einzigartigkeit dieser fragilen Ökosysteme vorstellt. Die Forscher kommen zu dem Fazit, dass dringend mehr Meereschutzgebiete um diese Habitate eingerichtet werden sollten.

Deep sea sponge ground

Deep-water sponge grounds are now emerging as a key element of deep-sea ecosystems. Its creating complex habitats hosting many other species. They are an important refuge in the deep ocean and they are also reservoirs of great species diversity, including commercially important fish. Playing a similar role to that of cold-water coral reefs with which they often co-occur, sponge grounds are even more ecologically and geographically diverse, consisting of many individual species and occurring in many places around the world.

This report highlights what is currently known about deepwater sponge grounds in terms of their distribution, biology, ecology and present-day uses in biotechnology and drug discovery, and introduces case studies of particular deepwater sponge habitats from around the world. This report also highlights the need to minimize the risk of damage to deep-sea sponge grounds through appropriate conservation and careful management, and presents further evidence of the need to improve awareness and understanding to ensure that future generations have the opportunity to explore, study and benefit from these vulnerable deepwater
habitats.
