Sir David's Snail Is Not A New Species

Yes and no!

This is only slightly related to politics - in the sense that it is a good example of how media coverage often misreports and sensationalises environmental stories - but I thought I should just correct the record on the prominent announcement of a "new" Tasmanian snail.  It isn't a new species and it wasn't discovered in December 2016 as many sources are claiming.  What has happened is that an existing species has been moved into a new genus.

Sometime in the late 19th century, pioneering Tasmanian land snail expert William Frederick Petterd collected some snail specimens near Eaglehawk Neck.  Doubtless noting that some of them were much larger than a species considered  widespread through the state, Petterd left an enigmatic (and for me at least illegible) note with the specimens, but did nothing further with them.  Live specimens of the snail were first collected in the early 1970s resulting in the description of the new species Helicarion rubicundus by Dartnall and Kershaw in 1978.  At the time this was treated as a fresh discovery of a new species, Petterd's earlier specimens having not been noticed.

2012 Ehrlich Award For Wrong Predictions Goes To ...

Introducing the annual Ehrlich Award, which at the start of each year will be given to the "wrongest" published prediction I observe of or relating to the previous calendar year. (Of course, if I make a really stupid prediction of my own pertaining to this or any other year, I will happily self-nominate, and even if necessary self-award. )

There are a few groundrules - for instance the predictions need to be vaguely meaningful (in terms of being able to assess whether they have happened - this year's winner stretches that one sometimes), and secondly predictions that carry a stated assessment of chance of falsehood are not included unless that assessed chance is ludicrously low.  After all, even odds-on favourites do get beaten sometimes. 

The Ehrlich Award is named in (dis)honour of Paul Ehrlich whose lifetime achievements in the field of publishing wrong enviro-scare predictions (oh no, you're an "idiot" if you say they were "predictions"; they were actually only "scenarios") are almost as staggering as the excuses trotted out on behalf of all his false apocalypses.  Apparently, not only is it a hit predictively for Ehrlich fans if something vaguely like the prediction happened, or if it could still happen later, but even if nothing like it happened, that's a hit too, because it means people must have listened to the prophet's warnings and, for that reason alone, averted their ways from their sins.
