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

“Not anticipated”, if you’ve been living under a rock for the past 5 years…

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…

The City of Platypuses!!

The measure for how excellent a city is should be how quickly you can see something wonderful.
It took less than an hour after arriving in #Hobart for @drdevildave.bsky.social and me to see a #platypus, which is of course the most wonderful thing there is. #Tasmania #MammalWatching #WildOz

Harry, why is your dog stealing quoll food!?

Should note that the devils can, & do, extract themselves from this situation perfectly well. There’s no denying them food…

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…

I am here for the Captain Quoll rebrand!!

Ecology needs a causal overhaul Ecology has yet to embrace causal inference, yet most questions in ecology are causal. Despite the common use of terms that imply causation, such as “shapes”, “drives”, or “impacts”, many studies shy...

I'm guessing this is probably very well worth the read! onlinelibrary.wiley.com/doi/epdf/10....

Cryptic Kultarr: Integrative Taxonomy Reveals Unrecognized Species of Carnivorous Marsupial (Dasyuridae: Antechinomys) in Arid Australia Conservation is impossible if we have not described all of the species we aim to conserve. This paper reviews the taxonomy of the kultarr (Antechinomys laniger) a small arid-zone specialist native to....

The kultarr is officially three species!
So proud of this work and a big thanks to Australia's amazing museum network and my great supervisor team

That’s a funky looking EQ - its vibe is all wrong!

A display of taxidermy of several species of Australian mammal, with a big green map of Australia.

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 ☺️

Busy start to #ICCB2025 - sharing @tasland.bsky.social ten year fauna camera data set - pre & post-fire at Five Rivers. Huge shout out to coauthors including @drdevildave.bsky.social & Jo Potts

This work was the result of a great collaboration between @tasland.bsky.social, @utas.edu.au, WWF Australia and the Tasmanian Quoll Conservation Program (made up in part by Bonorong Wildlife Sanctuary, Devils@Cradle, East Coast Nature World & Trowunna Wildlife Sanctuary)

A nesting box full of quolls, with both colour morphs (dark & fawn) represented.

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

We also wanted to examine the genetic effects of the supplementation, so sampled the next generation of quolls post-release.

This was a key part of an Honour's project by Jessica Morrison, who's the lead author on the study

A population supplementation of eastern quolls occurred @tasland.bsky.social's Silver Plains property, to boost a flagging population of this threatened species. Results were encouraging, w/ high survival & low dispersal of captive-bred quolls.
