Paper pun goals!

"I knew you were truffle when I walked in" is a magnificent title for a paper about baiting for mycophagous (fungi-eating🍄) mammals (like this long-nosed potoroo!)

The model was tested against the field estimates of an expert devil researcher*, with agreement in 95% of age estimates.

Personally, I view this as a win for both the model & my own field skills 🤓

Integrating multiple field measurements in a Bayesian parallel regression framework to estimate Tasmanian devil age The Tasmanian devil is a carnivorous marsupial, endemic to Tasmania, that is threatened by a transmissionable cancer. This paper introduces a novel method to incorporate multiple measures of devil si....

Tasmanian Devil Average Birthday also seems like a good day to highlight a new paper from Dr Douglas Kerlin, which uses different field measures of devil tooth development & wear to estimate age -

Happy Tasmanian Devil Average Birthday, to all those who celebrate! 🥳

Devils have an annual mating season, which goes from late Feb until late April. That means, on average, devil joeys are born on 1st April.

So if you wish a devil Happy Birthday today, you’ve got a good chance of being correct!

Random Delightful Fact of the Day -

Eastern quolls go grey as they get older!

A juvenile (~6 mths old) on the L, & a 4 yr old on the R

(Worth noting that 4 yrs old is oooooold for an eastern quoll)

It's bizarre. I can think of at least 3 scientific publications that predict (i.e., model) the uncontrolled explosion of deer across Tas. None of them were referred to in the report. weirdddd

'Not anticipated': New survey shows deer population boom in Tasmania The first survey for feral deer in Tasmania in five years reveals an unanticipated increase of nearly 20,000 to the population.

“No anticipated” except by all of us that have been saying for ever that the #feral #deer management plan is pathetic. 🌎 #wildoz

Feral deer are a huuuuge problem in Tasmania that’s only getting worse. Legislation catching up with reality would be a good start - incredibly, they’re still a partly protected species…

Oh wait, no it isn’t… The devil has comically managed to insert the entire front half of his body into the narrow tube. It looks like he is entering another dimension

As part of eastern quoll translocation work, we use supplementary feeding stations that are meant to exclude Tasmanian devils.

The devils disagree…

A taxidermy eastern quoll. The map on its label suggests the quoll lives in Tasmania (where it still does live today) and the southeast of the mainland (where it became extinct)

You can date a display of Australian mammals by whether the distribution maps recognise recent extinctions. Eastern #quolls went extinct in mainland Australia in the 1960s, but they're still on this historic display at @hunterianglasgow.bsky.social Zoology Museum.

Whoops, sorry - that wasn't meant to be the take-home! The captive-bred quolls did great, we just have to refine methods in terms of which individuals are released to help them with breeding. So a focus on juveniles & adults who have bred previously in future, which is exactly what we're doing ☺️

Another interesting side finding was the first (that we know of) genetic confirmation of multiple paternity in eastern quolls, with multiple litters found to have been fathered by more than one male quoll!

Useful lessons to be learned from this for future translocations of this species, with a key one being around releasing reproductively naive adult quolls. They were able to survive well in the environment, but may not have been able to translate that to breeding success.

However, genetic analysis of the next generation found no evidence that any of them had a captive-bred parent!

While we may have missed some juveniles in our sampling, this (at the least) indicates that the captive-bred quolls had lower breeding success than their wild counterparts
