A single plant or ‘clone’ of the Poseidon’s ribbon weed (Posidonia australis), a species of seagrass that occurs in the southern half of of Australia, in the UNESCO World Heritage Situation of Shark Bay is no longer any no longer as much as 4,500 years extinct and spans higher than 180 km in fragmented, shut to-shore meadows.

The UNESCO World Heritage Situation of Shark Bay is home to 1 of many largest loyal seagrass meadows in the sphere.
Identified as Gathaagudu to the aged custodians, the Malgana Peoples, it creates habitat for a biodiverse marine atmosphere together with 12 species of seagrass.
The positive, shallow waters all thru many of the Bay mean that seagrass meadows are uncovered to saturated gentle stages, abilities a huge annual fluctuate in temperature, on the total 17-26 levels Celsius even even though temperatures can exceed 30 levels Celsius in summer.
Finest, perennial, seagrass meadows of the Poseidon’s ribbon weed and the wire weed (Amphibolis antarctica) dominate much of this marine ecosystem, establishing an very best location in which to seem at evolutionary trade and adaptation.
“Our project started when researchers wished to fancy how genetically various the seagrass meadows in Shark Bay had been, and which vegetation wants to be mild for seagrass restoration,” stated Dr. Elizabeth Sinclair, an evolutionary biologist in the College of Natural Sciences and the Oceans Institute on the College of Western Australia and the Kings Park Science.
“We in most cases catch requested how many varied vegetation are rising in seagrass meadows and this time we worn genetic instruments to respond it.”
“We sampled seagrass shoots from all thru Shark Bay’s variable environments and generated a ‘fingerprint’ the usage of 18,000 genetic markers,” added Jane Edgeloe, a pupil in the College of Science and Engineering at Flinders College.
“The respond blew us away — there changed into once supreme one! That’s it, supreme one plant has expanded over 180 km in Shark Bay, making it the largest known plant on Earth.”
“The gift 200 km2 of Poseidon’s ribbon weed meadows seem to be pleased expanded from a single, colonizing seedling.”
“Our be taught offers an actual ecological conundrum,” stated Dr. Martin Breed, an e
