In Rapidly Warming UK, Wild Mushroom Species Reproducing 2X Per Year Instead Of Once - New Scientist

[hatrack]

It is perhaps the most striking example of how global warming is turning up the heat on the world's wildlife. Across the UK, wild mushrooms are reproducing twice a year instead of the usual once, the first time climate change has been reported to affect the life cycle of any organism in this way.

Many fungus species spend their lives in the soil as a fibrous mat called a mycelium. Once a year they reproduce, forming the fruiting bodies that are the familiar caps and stools that speckle forest floors. In the UK, this used to happen around September, during the onset of the British autumn. Now all that has changed.

Within just 50 years, many fungi have doubled the length of their breeding season from 33 days on average to 74, according to a survey of 315 species conducted by Alan Gange at Royal Holloway, University of London, UK, and colleagues. Species now appear above ground in July, mainly as a result of warmer temperatures, and the scarcity of frosts means they keep breeding into December.

Positive effect
More significantly, many have also switched to reproducing twice a year, fruiting once in the British spring and again in the autumn, something unheard of before temperatures began to climb in the mid-1970s. "The most astonishing thing from our analysis is that 30% of the species we looked at now fruit in May as well," says Gange. Gange believes that the fungi used to be kept in check by sharp frosts earlier in the year. As temperatures have climbed, and the frosts disappeared, there is nothing forcing the fungi to remain dormant in the soil. "Now the fungi grow, and with the rain in March they fruit and appear in April or May," he says.

7. Well, slime mold is a subset of fungi, correct?

:evilgrin:

I intend to collaborate and assist them in rounding up undesirables to toil in the manure mines.

4. At least when the crap hits the fan

There will be plenty of 'shrooms to ease the pain :D

5. Yeah, but heat reduces psilocybin production

Global Warming: Bad for the Earth, Bad for Your Head.

9. Get Katie Couric on the phone! There IS happy news about Climate Change!

2 season of mushrooms per year! Take that Al Gore!

World famine? Ha, mushroom soup for everyone!
