The Smoky Mouse (Pseudomys fumeus) is an elusive and endangered rodent native to southeast Australia. Historically, the Grampians in western Victoria have been home to healthy populations of the mouse, though years can pass without observations of the species. During the November 2012 Museum Victoria Bioscan, we found a large population of Smoky Mice in the Victoria Range in the west of the Grampians; an amazing find as the mouse had not been detected in such high numbers since the 1980s!

In February 2013 a wildfire burnt through 35,000 hectares of the Grampians, including 80 per cent of the Victoria Range and the locations we surveyed in November. While such a large fire raised concerns about the survival of the Smoky Mouse population, we’re using the opportunity to understand how the species responds to fire. So far things are looking promising: earlier this month we found evidence of rodent activity in a small sheltered patch in the middle of a burnt gully and the vegetation is regenerating well. Excitingly, Parks Victoria staff have detected Smoky Mice on cameras in the southern end of the Victoria Range.

Fire has shaped the communities of plants and animals that live in the Grampians, but we still have so much to learn about the role it plays in the lives of our native rodents. Regular burns are essential to the reproduction of some plant species, which in turn provide habitat for our animal species. The Smoky Mouse relies on specific plant communities to provide food and shelter; fire is necessary to ‘reset’ these plant communities to prevent them growing to a point where they are no longer suitable for the mouse. However, fire is best delivered in a patchy mosaic, allowing animals to live in unburnt areas while adjacent burnt areas regenerate and the plant community returns to a suitable state. Wide-scale fires like the one in February are not ideal, and we’re eager to learn what impact it may have on the native fauna.

We’re hopeful that the Smoky Mouse is living in unburnt patches throughout and around the burnt areas. Over time the Smoky Mouse will recolonise the recently burnt areas and we’ll be able to map the movement of the species across the landscape using genetic techniques. In the short term, I will be hiking around the Grampians monitoring the progress of the Smoky Mouse over the next year. I hope to learn where the mouse is persisting and how the species responds to fire in order to help plan management techniques to ensure the conservation of the species for generations to come.

There are round ones, black ones, orange ones, blue ones. Compound, stalked and spots. Some animals have two, others eight or perhaps 100. Eyes see amazing things and they’re amazing to look at.

I’ve spied many a curious eye looking back at me underwater. Here are 19 fishes, three octopuses, three squid, two rays, a scallop, a seahorse, a shark and a shrimp. Thirty-one belong to marine species, one lives in freshwater. See how many species you can recognise.

The Spencer & Gillen: A Journey through Aboriginal Australia website was launched last Friday at a celebration at Melbourne Museum. In attendance were MV staff, representatives from several partner institutions, Central Arrernte Elders, and descendants of the two ethnographers, Walter Baldwin Spencer and Frank Gillen.

The website has been several years in the making and brings together over 50,000 objects, photographs, documents, recordings and drawings that are housed in institutions in Australia, Europe and the United States. Research coordinator Jason Gibson calls it "one of the most comprehensive collections to do with a group of Aboriginal people. Certainly there’s nothing else like it on the web. It covers life on the frontier in Central Australia between 1875 and 1912."

Among the treasures are rare and wonderful audiovisual recordings, including the earliest film footage taken on mainland Australia. "Most of this material isn’t available on the web anywhere else, so we had to digitise and compile it at the same time," explains Jason. With a new mapping function and many ways to sort and filter the collection, you can now access these vital ethnographic records in ways never before possible, which is particularly important for members of Arrernte communities. "We spoke to over 80 different individuals from five different language groups, mainly in Alice Springs and Tennant Creek and overwhelmingly everyone is really excited and proud to have their heritage on display for all to see."

Spencer and Gillen worked in Central Australia for 30 years. "Although they have been criticised by many people for their social evolutionist attitudes, this collection demonstrates the collaboration with local people," explains Jay. "Gillen’s very close relationship with Arrernte people was unusual at the time and they were among the first non-Indigenous people to grapple with the concept of the Dreaming. 'Dream time' was a Gillen interpretation of the Arrernte word Altyerr and this interpretation became important internationally in terms of thinking about religion and society."

The website is the product of a collaborative project that was funded by the Australian Research Council and led by the Australian National University. It would not have been possible without the partner organisations especially the South Australian Museum, Northern Territory Library, and the Pitt Rivers Museum.

All I want for Christmas is an update on the Android field guide!

Well – drumroll – it's here!

Last Friday, we were very proud that Senator The Hon Don Farrell, Minister for Science and Research and Minister Assisting for Tourism, was able to join us at Melbourne Museum to celebrate this significant milestone.

Development of the Android version is part of a wider project, funded by the Australian Government under the Inspiring Australia, Unlocking Australia's Potential scheme, where we are working with museums around the country to deliver field guide apps for all States and Territories.

The MV Field Guide app is now available through Google Play for Android devices – including tablets, phablets and phones. And it's free.

Apple device users will be able to download an updated iOS version in the coming weeks. The new version represents a significant upgrade to the existing iOS app.

Additions to the new Android app (and coming soon for Apple devices) include:

• Over 30 new species (many added as a result of user requests), including the Great White Shark, the Giant Gippsland Earthworm and Victoria's bird emblem, the Helmeted Honeyeater
• New marine mammals: seals, dolphins, whales
• 75 new bird calls, including the Powerful Owl, the Little Penguin, the Tawny Frogmouth, the Sacred Kingfisher and the Red-tailed Black Cockatoo
• The complete set of frog calls
• The updated Victorian Endangered Status for all vertebrate species (bringing the app in line with the DSE's 2013 Advisory List for Threatened Vertebrate Fauna)

On Saturday 23 March, we returned to Melbourne from our expedition to Sulawesi, Indonesia. Our last week we spent at the Museum Zoologicum Bogoriense sorting specimens and preparing permits to return to Australia. A week earlier on 16 March, we left our camp in the forest of Mount Dako on the island of Sulawesi. We hiked all day from 1600 metres above sea level to the village of Malangga Selatan at 200 metres. Our team at 400 metres elevation also left camp and met us in the town of Toli Toli.

It wasn’t easy to get to our camps on Mount Dako. After a week of permits in Jakarta, a week of scouting two mountains, and several days arranging local assistance, we finally arrived in Malangga Selatan ready to hike up the mountain. With over 300 kg of gear, our team of ten researchers, and fifty local men waiting to help us up the mountain, our local guide, Jamudin, suddenly expressed concern about water on the mountain. Apparently we were going farther into the forest than he was accustomed. We showed him the many drainages on the map that all fed into a big river to the east, but our only option to convince him was to send another scouting party two days hike up the mountain. The rest of our team and the porters set the low elevation camp. After two days, I reached the crest south of Mount Dako with our scouting party and made camp beside a small stream. That night the rain fell heavy for several hours and our tent flooded in the rain. We sought shelter with our guides under a tarp and spent several hours sitting on a small log until the rain subsided enough to return to our tent. The next day we sent two of our guides down the mountain to return with the rest of our team and our gear two days later. We moved our camp to a drier location farther up the ridge and enjoyed the only two days without rain for the rest of our trip.

Our high camp was set in lower montane rainforest with moss-covered trees including oaks and pandanus. Even when it’s not raining, clouds bring moisture to the forest and there is nearly constant dripping. Orchids and pitcher plants grow in the moisture of the moss. Spiny rotan erupt from tiny plants on the forest floor to tree size vines emerging from the canopy. They climb with the aid of curved thorns that grip human hands and bodies as easily as the trunks of trees.

Over the last two weeks, our two camps documented 26 species of bats, rats and shrews and 31 species of birds in the forests of Mount Dako. In total, our surveys produced nearly 500 mammal and 150 bird records.

We documented a wide range of mammal species including the giant rat, Paruromys dominator, the small orange-brown rat, Maxomys musschenbroekii, the long-haired rat, Rattus xanthurus, the soft-furred rat, Bunomys penitus, and the small arboreal mouse, Haeromys minahassae. We documented two squirrels, the small arboreal, Prosciurillus murinus, and the long-nosed, terrestrial, Hyosciurus ileile. We also documented five species of shrews, including the dark-furred, Crocidura rhoditis.

Many endemic and beautiful bird species were documented as well, including the Green-backed Kingfisher, Lesser Sulawesi Honeyeater, Sulawesi and Hair-crested Drongos, Malia, Philippine Scrubfowl, Yellow-flanked Whistler, Fiery-browed Starling, Golden-mantled Racquet-tail, and two species of small hawks, the Spot-tailed Goshawk and Vinous-breasted Sparrowhawk.  Many species of fruit-doves were also noted, including the Sulawesi Ground-dove, Purple-crowned Fruit-dove and Black-naped Fruit-dove. Population densities of several species were high, including the Yellow-sided Flowerpecker. This species is in the same family as Australia’s Mistletoebird, which is often only found singly or in pairs. An exciting find was the large Ashy Woodpecker. Sulawesi represents a limit to the distribution of woodpeckers, which are found world-wide with the exception of the Australo-Pacific region.

Our return to Melbourne is only the beginning of our studies as now we begin the cleaning and detailed examination of specimens, including genetic sequencing and comparison to described specimens to confirm identifications and examine geographic variation within species. Our collections from Mount Dako are a rare collection from the western portion of the northern peninsula of Sulawesi. They will help us understand the diversity, distribution, and origin of species on the island of Sulawesi and its significance in the biogeography of the Indo-Australian region. That understanding will emerge through our research at Museum Victoria and our collaboration with the Museum Zoologicum Bogoriense and our international partners in Canada and the USA. 

Chauliognathus lugubris. The Plague Soldier Beetle. This wee beast accounts for hundreds of insect identification requests we receive at the Discovery Centre during the summer. At this time of year these little pollinators descend from the crowns of flowering trees to indulge in seething masses of mating activity triggered by hot weather.

This frenzied 'coupling' activity rarely goes unnoticed, especially because of the numbers in which the beetles congregate– we often get calls from people describing masses of these little cigar-shaped critters with their distinctive orange collars in their gardens; regular readers will have read our earlier post about Plague Soldier Beetles.

Last week, however, it seems this beast and its plaguing behaviour caught the attention of the Rainbow Lorikeet class at Dame Nellie Melba Kindergarten in Richmond. The Lorikeets' teacher Adam contacted us with an identification request, accompanied by some photographs and observations of the insects in question from the students, some of which I’ll share below:

It has 3 legs and 3 legs (from Sylvie). They have two antennae (coming) out of their head (from Andrew and Hugo) 

A great start for young eyes – these are key characteristics of insects that separate them from other arthropods

I think it's a stink bug (from Ralph) and I think it's a beetle (From Taj) 

These are also good observations. Like the animals we call 'stink bugs', they can emit an unpleasant liquid as a defence mechanism.

I think it's a grass hopper (from Harry) 

Harry isn’t quite right here, but the plague behaviour is similar to locusts, so still a good observation.

It's a beetle and he flies away and he has the mummy and the daddy and the baby and the dog (from Jed) 

Apart from the bit about the dog, Jed is also on the money.

I think they only come out once a year in summer (from Grace) 

Grace has also hit the nail on the head – clearly we have some budding entomologists here!

They carry each other (from Lucas) 

In a manner of speaking, yes they do – but we may leave this to Lucas's guardians to explain further if required.

As seasoned respondents to enquiries of all types from the public, we thought the Rainbow Lorikeets were particularly clever in separating their observations into 'what we think' and 'what we know' – in doing so, they were more than half-way there with their identification by the time it reached us. This, along with the photos, made our entomologist’s job quite easy in providing the identification as Plague Soldier Beetles.

Well done Rainbow Lorikeets, we in the Discovery Centre are impressed with your entomology skills!
