The Great Barrier Reef has lost half its corals in just 20 years, study says

The population of corals within Australia’s Great Barrier Reef has plummeted by 50 percent in the last two decades, according to a new study published on Wednesday.

Researchers from the ARC Centre of Excellence for Coral Reef Studies in Queensland, Australia, assessed the colony size of corals in the reef — the world’s largest — between 1995 and 2017, and found a drastic depletion in the population of small, medium and large coral.

“The decline occurred in both shallow and deeper water, and across virtually all species, but especially in branching and table-shaped corals,” study co-author Professor Terry Hughes said of the findings, published in the Royal Society journal.

These specific corals are especially important in providing a habitat for marine life such as fish that inhabit the reef, the researchers said, meaning their loss also results in a decline in reef biodiversity. Despite covering less than 0.1 percent of

Everyone can play a part in conserving Australia’s World Heritage-listed Great Barrier Reef — ScienceDaily

Many Australians do not know what they can individually do to make a difference to the health of the World Heritage-listed Great Barrier Reef (GBR), according to a survey led by QUT researchers.

The researchers found most Australians are not making a connection between climate change and reef health and say there is more individuals could do on this front, both in the home and to influence government policies.

Senior Research Fellow Dr Angela Dean conducted the online survey of 4,285 Australians with Professor Kerrie Wilson, Director of QUT’s Institute for Future Environments, and Dr Robyn Gulliver from the University of Queensland.

The resulting paper, “Taking action for the Reef?” — Australians do not connect Reef conservation with individual climate-related actions, has been published in Conservation Letters: a journal of the Society for Conservation Biology.

“While there are many threats to reef health, including poor water quality stemming from

The bleaching of corals off Australia’s northeastern coast due to ocean warming and acidification is happening across all species and to specimens of all ages, according to a new study that analyzed coral demographics. The study, led by Andy Dietzel at the ARC Centre of Excellence for Coral Reef Studies in Australia, confirmed the Great Barrier Reef lost half its corals between 1995 and 2017.

“We measured changes in colony sizes because population studies are important for understanding demography and the corals’ capacity to

Streaming giant Netflix quietly did away with its 30-day trial in the U.S., according to CNET, just like Disney+, which stopped offering free trials back in June. The U.S. is not the only market where Netflix has decided to end its free trial. The company ended trial periods in Mexico and several other countries as far back as two years ago.

Looking for Dividends? These 3 Tech Stocks Are Great Buys

Looking for investment income? Focusing on yield alone means you’ll miss out on lots of quality companies that pay a smaller dividend, but are still growing and could increase the payout in the future. Looking for companies that check both boxes — dividend payment and growth — can create a powerful compound growth effect over the long term.

Three companies our Fool.com contributors think meet these criteria are Applied Materials (NASDAQ:AMAT), Dolby Laboratories (NYSE:DLB), and Broadcom (NASDAQ:AVGO).

3,500-pound great white shark dubbed “Queen of the Ocean” spotted off North America’s coast

A 3,500 pound great white shark dubbed Nukumi — meaning “Queen of the Ocean” — has been spotted off the coast of Nova Scotia. The massive 50-year-old shark was tagged and released by Ocearch, a research and exploring team that hopes its latest trip out to sea provides new clues to unravel the mysteries of great whites.

“When you see these big females like that that have scars from decades over their lives and multiple mating cycles, you can really kinda see the story of their life unfolding across all the blotches and healed wounds on their body,” team leader Chris Fischer told CBS News’ Jeff Glor. “It really hits you differently thank you would think.”
