Sunken body found by divers offers clues to American origins

The ancient remains of a teenage girl discovered deep underground in Mexico are providing additional insights on how the Americas came to be populated.
Divers found the juvenile’s bones by chance in a vast, flooded limestone chamber on the Yucatan Peninsula.
Aged 15 or 16 at death, the girl lived at least 12,000 years ago.
Researchers have told Science Magazine her DNA backs the idea that the first Americans and modern Native American Indians share a common ancestry.
This theory argues that people from Siberia settled on the land bridge dubbed Beringia that linked Asia and the Americas some 20,000 years ago before sea levels rose.
These people then moved south to populate the American continents.
The genetics of modern Native Americans would certainly appear to link them into this story. But their facial features set them apart from the oldest skeletons now being unearthed.
These ancient people had narrower, longer skulls. The differences have hinted that perhaps there were multiple immigrations from Siberia (or even Europe).
However, the remains of the Yucatan girl, dubbed Naia – which means “water nymph” in Greek – does not follow that line of thinking, because although she had the slender features associated with the earliest Americans, her DNA shares commonalities with modern Native Americans.
Lab analysis of teeth and bone samples link her to a particular genetic lineage known as Haplogroup D1.
This same marker is found in substantial numbers of modern Native Americans.
“This lineage is thought to have developed in Beringia, the land that now lies beneath the Bering Sea after its ice age occupants became genetically isolated from the rest of Asia,” explained lead author Dr Jim Chatters.
“Thus, Naia, one of the earliest occupants of the Americas yet found, suggests that Paleoamericans do not represent an early migration from a part of the world different than that of the Native Americans.
“Rather, Paleoamericans and Native Americans descended from the same homeland in Beringia.
“The differences between them likely arose from evolution that occurred after the Beringian gene pool became separated from the rest of the world.”

Euro-Divers opens to guests at Alila Kothaifaru Maldives

In celebration of Euro-Divers’ 50 Years of Diving with Friends in the Maldives, the team have opened a new PADI 5 Star Dive Center at Alila Kothaifaru Maldives.

Alila Kothaifaru Maldives retreat lies at the northern edge of the Maldives in the tranquil Raa Atoll, reached via a panoramic 45-minute seaplane voyage from Male. The island has 80 all-pool-villas, 36 of which are over water with a private pool for your enjoyment and 44 beachfront villas designed seamlessly to immerse guests in the natural surroundings. In support of sustainable tourism, Alila hotels adopt Earth Check operating standards, integrating their environments’ natural, physical, and cultural elements.
Raa Atoll is well-known for the excellent scuba diving it offers. The underwater landscape of Raa Atoll is characterized by a high number of thilas scattered inside the lagoons. These underwater coral mountains are magnets for marine life including huge schools of tropical reef fish, a generous splash of colour, iconic bucket-list-must-see marine creatures including sharks, mantas (appearing during the entire year), turtles, and uncrowded dive sites—a perfect diver’s heaven for beginners and experienced divers. We offer a full range of PADI courses for different levels. From November till March, the Manta cleaning station is located 15 minutes away by boat.

The team from Alila Kothaifaru Maldives look forward to welcoming you soon.

Marine Life & Conservation
Blue Marine Foundation launches new partnership with Dutch Caribbean Nature Alliance

Ocean charity makes initial grant of $90,000 to marine parks on six Dutch Caribbean islands. Award will fund projects including coral protection, and training youth marine rangers.
Ocean conservation charity Blue Marine Foundation has announced it is awarding $90,000 in funding to support marine conservation in the Dutch Caribbean. A range of projects run by protected area management organisations on six islands will each receive a grant of $15,000. The funding is the first step in a longer-term partnership to support the islands and help secure sustainable financing through the Dutch Caribbean Nature Alliance (DCNA) Trust fund.
To improve ocean governance, Blue Marine uses a combination of top-down intervention and bottom-up project delivery to help local communities at the front line of conservation. It will work together with the DCNA to help marine-park organisations protect the unique and threatened biodiversity of the Dutch Caribbean.
The new partnership is an important development in the successful management of marine conservation parks in the Dutch Caribbean. The UK-based charity has established a small-grants fund to provide rapid access to support for critical conservation projects run by marine parks.
The individual projects and their local partners are:
- Aruba: monitoring water quality in its Marine Protected Area (MPA) and wetlands, in conjunction with Fundacion Parke Nacional Aruba (FPNA)
- Bonaire: assessing losses of stony corals (Acroporids e.g. staghorn and elkhorn coral), and their potential future recovery, in conjunction with Stichting Nationale Parken Bonaire (STINAPA Bonaire)
- Curaçao: establishing a bus transport marine education program and youth marine ranger program, in conjunction with Caribbean Research and Management of Biodiversity (CARMABI)
- Saba: provision of a climate control room for the new marine field station, in conjunction with the Saba Conservation Foundation (SCF).
- Sint Eustatius: assessing the health of coral, the abundance of fish life and the diversity of reefs, in conjunction with Eustatius National Parks Foundation (STENAPA)
- St Maarten: monitoring marine habitats, in conjunction with Nature Foundation St. Maarten (NFSXM)
Unique ecosystems on the islands are vulnerable to threats such as feral livestock causing sedimentation on reefs, and invasive species, including lionfish and coral diseases. They are also at risk from overfishing, climate change, coastal development, erosion and the build-up of harmful algae caused by waste water.
The islands of the Dutch Caribbean are also home to important “blue carbon” habitats – ocean ecosystems such as seagrasses, mangroves and other marine plants that suck up and lock away carbon from the earth’s atmosphere. Seagrass is so efficient at this it can capture and store carbon dioxide up to 35 times faster than tropical rainforests. The management and protection of these blue carbon habitats is vital in the fight against climate change.
Current marine conservation measures in the islands include a 25,390 square km mammal and shark sanctuary- Yarari sanctuary- across the Exclusive Economic Zone of Bonaire, Saba and St Eustatius. All six islands have inshore Marine Protected Areas ranging in size from 10 to 60 sq km.
Blue Marine’s Senior Project Manager Jude Brown commented: “Having recently visited two of the islands, I witnessed first-hand how special this region is. Diving the waters off Saba I saw huge Tarpon swimming amongst shoals of blue tang, and hawksbill turtles feeding on the seagrass beds. I also witnessed the challenges these islands are facing from coral disease to issues with coastal development. It is an exciting opportunity to work in the Dutch Caribbean, bringing expertise and funding from Blue Marine to join with the wealth of knowledge already on the islands, to work together to protect the important marine life arounds these islands.”
Tadzio Bervoets, Director of the DNCA commented: “The Dutch Caribbean consists of the Windward Islands of St. Maarten, Saba, and St. Eustatius and the Leeward Islands of Aruba, Bonaire and Curaçao. The nature of the Dutch Caribbean contains the richest biodiversity in the Kingdom of the Netherlands. The diverse ecosystems are a magnet for tourism and at the same time the most important source of income for residents of the Dutch Caribbean. Nature on the islands is unique and important but it is also fragile. The coming week we will be in The Netherlands to present a Climate Action Plan for the Dutch Caribbean to emphasize the urgent need for a climate smart future for our islands.”
