“Power plant” without DNA

The cells of most living things have special structures that are responsible for energy production. These so-called mitochondria usually have their own genome, in addition to that in the nucleus. Uwe John of the Alfred Wegener Institute (AWI) and his colleagues have now uncovered a hitherto unique exception in a single-celled parasite. The mitochondria of the dinoflagellate Amoebophrya ceratii seem to function properly even without their own genetic material, reports the team in the journal Science Advances.

Canary Islands: whale watching instead of dolphinariums

South Africa: Death trap for dolphins defused

The most dangerous shark net at the coast of South Africa has been dismantled. For many years, this net was also named "net 99" (in Richards Bay in KwaZulu Natal). The reason it has been installed was that it should protect surfers and swimmers from shark attacks. In the last decad, 15 endangered humpback dolphins died in this network. At the same time, "net 99" only warded off a single potentially dangerous shark. Now the net has been replaced by four baited hooks (drumlines).

Gillnets endanger harbour porpoises of the Baltic Sea

The protection status of the inner Baltic Sea porpoises has recently not been included in the list of migratory species at the highest level in Annex I to the Convention on the conservation of migratory species (CMS); despite a request by the Whale and Dolphin Conservation Society (WDC) and the Coalition Clean Baltic (CCB). The reason is that the Baltic porpoise is not a separate species and thus the German Federal Ministry of Food and Agriculture (BMEL) does not consider it to be particularly worthy of protection.
