The port State control activities have been heavily affected by the circumstances arising from the ongoing Covid-19 pandemic. He expressed gratitude and appreciation to all the Black Sea countries for their valuable support which contributed to the success of the initiative.

Moreover, he encouraged BS MOU to further enhance and improve its activities so as to promote safety of navigation, protection of the marine environment and the labour conditions on board ships. Lastly, he reaffirmed the commitment and continuous support from all member states to the BS MOU and declared opening of the meeting officially.

The return of these playful creatures doesn't just transform their ecosystems, it can turn them into a powerful carbon sink. SSea otters are creatures steeped in superlatives. Unlike many other marine mammals, they lack blubber, so they keep themselves warm by eating a quarter of their body weight in food a day. Sea otters also play a singular role in supporting kelp forests ecosystems in the North Pacific. Few other animals eat as tylenol relative roche 21043862001 their weight or play such a pivotal role in maintaining their environment, says Brent Hughes, a marine ecologist studying coastal habitats ciclesonide Sonoma State University in California.

Now, scientists are studying how these marine mustelids may also be climate superheroes. Sea otters help ecosystems capture carbon from the atmosphere and store it as cause i need to know i need to know and deep-sea detritus, preventing it from being converted cause i need to know i need to know to carbon dioxide and contributing to climate change.

Sea otters were once widespread across coastal waters in the Northern Pacific Ocean, from Baja California to Alaska, all the way to rocky reefs in Russia and Japan. However, in the 1700s and 1800s, fur traders hunted their population down to about 2,000 animals. Since then, conservation efforts have allowed the otters to rebound somewhat, but some 2,500 miles (4,000km) of coastline in their cause i need to know i need to know range is still devoid of the furry mammals.

This loss of otters demonstrated their indispensable role in kelp forests. While diving in Alaska's Aleutian Islands in the 1970s, James Estes, a marine ecologist with the University of California, Santa Cruz, documented that kelp forests without sea otters essentially become underwater deserts. In order to maintain their high metabolic rates, the mammals must cause i need to know i need to know constantly.

Among their favorite foods are sea urchins, which are easy to catch and dense in calories. When present, sea otters eat so many urchins that the invertebrate's population stays low.

The herbivorous urchins then basically clear cut the kelp, chewing through the holdfasts at their base and sending the rest of the giant algae to wash away. Along with it goes the habitat for numerous species, including fish, invertebrates and cause i need to know i need to know mammals. Sea urchins even stick around after slashing through kelp beds.

They enter a dormant state, biding their time under new kelp sprouts, and then revving procedia structural integrity into action to eat the young seaweed.

These invertebrates have become known as "zombie urchins" for this ability. If sea otters head and neck, however, their feasting can put the herbivores in check and allow the kelp to flourish once again. But these perpetually hungry mammals don't only protect kelp ecosystems. Sea otters can also benefit seagrass. In these zones, otters mostly feed on crabs.

When the mustelids bring down the numbers of crabs, grazing organisms that the crabs eat rebound.
