I’m currently working my way through 162 invertebrate samples from 27 sites in the Otway Ranges with the aim of understanding the effect fire has on flying insect population structure in Australia. Existing Australian studies on fire and insects have primarily focused on terrestrial and litter dwelling invertebrates, which may have a different response to fire than their flying counterparts. Studies that include flying insects have been conducted overseas in forests where the vegetation structure is very different to that of Australian forests.
Right now I’m working through all of the beetle samples, the order in which we collected the highest number of individuals. My results will hopefully add to our knowledge of the current global pollinator decline, and aid future research on the recovery of insectivorous animals after fire. All the disruption from coronavirus has really slowed things down for me but I’ve finally gotten my hands on my insects again and can carry on while I work from home.
As a research group, we've given a disproportionate level of attention to furry animals over the past few years, but Emma Window is helping redress the balance with her study of the effects of fire on flying insects. Given that she's been unable to visit the lab under coronavirus, she's got the lab to come to her!
While a large team has worked in the Casterton region as part of the Fire & Fragmentation Project, Simeon has been going it alone on a closely-related project in the Adelaide Mount Lofty Ranges.
As the name suggests, the hills are precipitous and the human population is much larger than it is in the forgotten corners of southwest Victoria and southeast South Australia. Simeon has contended with bushfires and equipment theft (not to mention coronavirus!), but has recently achieved the great feat of tagging hundreds of thousands of camera-trap photos single-handedly!
As of last week, I have finished going through the vast numbers of images from my camera traps that I set between last October and March, and extracted all the data about what species were detected at each of my 129 sites (this is 3 less than I had previously, due to the Cudlee Creek fire and several missing cameras).
The following article by Lucy Smith was originally published in Australian Geographic and features Amy Smith's and Rachel Nalliah's PhD and Masters research (respectively).
Without Amy and Rachel's incredible trap-wrangling efforts and invaluable help from Erin Thomas and other students and volunteers, the life and times of the Glenelg Region's endangered heath mice would be set to remain a mystery!
LADIES AND GENTLEMEN, meet the dayang (Pseudomys shortridgei) – heath dweller, flower feaster and day napper. At a petite 9.5-12cm, this long-whiskered lovely is a member of the Old World rat family, which will no doubt send shivers down the spine of musophobes! But fear not rat haters, this bobble-eyed, endangered heath mouse is at the cutting edge of scientific research into the link between fire and native species’ survival.
Lucy Smith holds a Master of Environmental Science, specialising in forest community ecology. Her interests span a range of ecological areas, including natural asset management in agriculture and the interaction between humans and wildlife.
We recently welcomed Milaan Heeskens but have had to wave him goodbye already because of COVID-19. Having struggled to find a flight, the Dutch Embassy came to his rescue and he was able to return home at the end of last week. Now we're welcoming Alex Santiago, who we hope will be able to stay for more than a few weeks! The prospects are good because he lives in Melbourne - albeit the chances of any face-to-face meetings through his Honours candidature are looking slim! The University has transitioned to a Virtual Campus so we're continuing our research from home. Please extend as warm a welcome to Alex as you can from behind your computer screen!
"I am an honours student working with the Fire Ecology and Biodiversity team, investigating fire and fragmentation in south-west Victoria. Under the supervision of Dr Holly Sitters, my project is investigating the influence of landscape-scale pattern on the genetic diversity of the South-eastern Slider skink. In 2017 skink tail-tip samples were collected by masters student Taylor Reid and sequenced using a relatively new method called DArT sequencing. We are hopeful that the use of genetic markers to infer population health across landscapes will assist in earlier and more effective management of populations and maintain species' persistence."
We'd like to extend a warm welcome to Milan Heeskens who's recently joined us from the Netherlands.
“I’m a 3rd year Dutch student studying applied biology at HAS University of Applied Sciences in the Netherlands. I have to fulfil 40 weeks of internship work this school year. I already have done 20 weeks of intern work at a water authority in the Netherlands (WL, Roermond). My project there was to investigate the effects of snags (dead wood) on the aquatic ecology of creeks. I researched that by catching macrofauna and compared that data with older data. It is amazing what creatures you can find in creeks and rivers.
"Now I am doing an internship for 20 weeks here at the School of Ecosystem and Forest Sciences in Creswick. I’m researching whether fire has a direct impact on animals or if it impacts animals indirectly. Indirectly means that fires changes plant material (maybe food) or impacts the predators of the animal species and in that way still impacts the animal itself.”
We've been busy talking about some of our favourite topics (fire, fragmentation, small furry animals) on community radio over the past few weeks.
Rachel spoke about her Masters study of the endangered heath mouse on 3CR's Lost in Science and Holly participated in a bushfire special on 3RRR's Einstein A Go-Go, which also featured Trent Penman and Lauren Bennett.
Both radio shows are available as podcasts:
Lost in Science on 3CR
Einstein A Go-Go on 3RRR
Congratulations to all our students who presented at the Victorian Biodiversity Conference last week, many of whom were presenting their work for the first time. Particular congratulations to Masters student Erin Thomas, who won the best poster award. Her poster on habitat partitioning in macropods not only included some great science, but also featured Erin’s own hand-painted pictures of her study species!
This article was written by Professor Alan York and was first published on Pursuit. Read the original article.
Congratulations to Annalie and Rachel who were awarded the Ecological Management and Restoration prizes for best presentation and best poster (respectively) at the Ecological Society of Australia's annual conference last Friday.
Annalie did an amazing job of distilling a complex analysis into a neat story about how edge contrast between patches of different time-since-fire benefited mammal species richness in the Otway Ranges. Rachel's eye-catching poster described a love triangle between fire, resource availability and the endangered heath mouse, making for another juicy ecological story!
Eight of our PhD and Masters students are presenting their work at the Ecological Society of Australia's annual conference in Launceston, Tasmania, this week.
This year's conference theme is Ecology: science for practical solutions and it spans six action-packed days. It's a wonderful forum for our students to talk about their work and get feedback from the wider ecological community.
Some of the team even found energy to walk along Cataract Gorge, providing a lovely opportunity to check out Launceston's beautiful scenery, spot some local birds, and take a few selfies!
