每日英語跟讀 Ep.K392: About Australia - World’s biggest plant discovered off Australian coast

The largest known plant on Earth - a seagrass roughly three times the size of Manhattan - has been discovered off the coast of Australia.


Using genetic testing, scientists have determined a large underwater meadow in Western Australia is in fact one plant.


It is believed to have spread from a single seed over at least 4,500 years. The seagrass covers about 200 sq km , researchers from the University of Western Australia said.


The team stumbled upon the discovery by accident at Shark Bay, about 800km north of Perth. They had set out to understand the genetic diversity of the species - also known as ribbon weed - which is commonly found along parts of Australia’s coast.


Researchers collected shoots from across the bay and examined 18,000 genetic markers to create a "fingerprint" from each sample. They had aimed to discover how many plants made up the meadow.


"The answer blew us away - there was just one!" said Jane Edgeloe, the study’s lead author.

Not a square to spare: Australian shops ration toilet paper amid coronavirus panic 一張都不分:澳洲商店在冠狀病毒恐慌中限購衛生紙

Australia’s major grocers put strict limits on purchases of toilet paper on Wednesday, after shoppers stripped shelves in a rush of panic buying spurred by fears over a coronavirus.


The demand for toilet paper, in particular, has sparked the trending hashtags #toiletpapergate and #toiletpapercrisis on Twitter, along with photographs of overloaded shopping trolleys, and calls for calm from baffled officials.


The biggest grocery chain, Woolworths Group Ltd, limited sales to four packs a shopper, to keep up stock levels while suppliers ramp up production.


Shoppers have swooped on other products also. Costco has put limits on purchases of milk, eggs, rice, disinfectants and soap.
