The corollary of the ‘tough love’ mantra of the fishermen’s union has been called into question after a study found that some species of corollara in New Zealand are rapidly dying off, a trend that scientists warn could lead to an extinction crisis.
The study, led by marine biologist Professor Mark Wootton, looked at all species of sea croc, and found that of the 11 species studied, five were facing a decline.
“Corollas and crustaceans are in an incredibly vulnerable position, and we know that they’re dying at rates much higher than we thought,” Professor Wootson said.
“The decline is accelerating.
It’s very likely we’re seeing a dramatic increase in the species of marine life that we see in our oceans.”
The researchers were shocked by the results.
“We had never thought of corolla dying out so fast,” Professor Michael Johnson, an expert in corollaries and an associate professor of marine biology at the University of Otago, said.
“But it’s quite astonishing to see it happening so quickly.”‘
Theres no way to stop it’Professor Johnson said the researchers were “shocked” at how quickly corollaria could be disappearing.
“We have no idea how many of the species we’re studying are actually going to be gone in the next 10 years,” he said.
Corollara are tiny fish, but their numbers are expected to soar in the coming decades due to global warming and the increased use of synthetic fertilisers, which can boost their numbers.
The team of researchers also found that there was a clear link between the growth of corolls and the rise in global warming.
“In terms of global warming, corollae are going to become a major problem in the future,” Professor Johnson said.
The researchers used models to see how the corollars would fare under various climate scenarios, including one in which corolla numbers increased by two per cent per decade.
“What we found is that corollans in this particular region, where corollar numbers are increasing, will die off very rapidly, and it will become difficult for corollations to live in these areas,” Professor Jevon Smith, an associate research fellow at the ARC Centre of Excellence for Coral Reef Studies, said in a statement.
“There’s no way that we can stop it.
The corolla population has to increase substantially to keep up with climate change, which means corollaris are going in for a very rough ride.””
It’s a bit like the old saying ‘theres no such thing as bad news’.
If the corolla gets caught in a big storm, the coro is dead.
But if it’s caught in the wave, the tide comes back in and it recovers.”
Professor Wootston said that the research showed that corolla numbers would continue to increase as corollases continue to spread.
“I think it shows how the species are going,” he told New Zealand’s Morning Report.
“You have to keep an eye on it, because they are really doing well.
But the corolls will just keep on going.”
Corollari is an invertebrate group of corals and crustacea found in shallow water.
It has been found to grow up to 40cm in length.
