Last week I was delighted to attend a workshop at Monash University focused on using EICAT methods to assess environmental impacts of invasive insect species. Thank you to Melodie McGeoch and her team (Dave, Chris & Rebecca), and Andrew and Carol from the Invasive Species Council, for inviting me in the first place, and for organising an excellent, productive week. We were also very lucky to have Sabrina Kumschick and Helen Roy there to share their expertise in developing and using EICAT.
It was a ‘proper’ workshop, i.e. a small group of researchers working on a project together with planned outcomes, rather than a training or upskilling ‘workshop’ (why aren’t they just called courses?!). As an early career researcher, it was so rewarding to be there. Research workshops have similar benefits to conferences, in that you have the opportunity to discuss new ideas and network outside your normal collaborative groups. But I find workshops much more fulfilling than conferences, because you have more time to develop those ideas, learn new perspectives, and really get to know people you may not otherwise cross paths with.

Keeping up with the literature is part of being a researcher. A few years ago, the #365papers hashtag started on Twitter, as a way to encourage academics to read more papers in a calendar year.
In reality, very few academics would actually read 365 full papers over a single year. #260papers, a paper every work day, was suggested as a compromise and, more recently, #230papers goes one step further to account for public holidays etc.
Have you ever felt underappreciated? As if people assume you can only contribute one skill to the world, and not much else…?
Imagine how bees feel. Not only do 99.9% of bee species live in the shadow of the European honey bee, most of the time they only get credit for pollinating flowers. And a few make honey. That’s all they do, right?
Actually, no. Bees do a lot of other things in their ecosystems. They have a very active life outside their relationship with flowers.
The stingless bees (Tribe: Meliponini) are some of the most intriguing. There are about 500 species of stingless bee around the world, mostly in tropical and subtropical regions. Like honey bees, they also make honey; albeit in gourmet, rather than commercial, quantities. (Their honey also has a very different flavour to the honey you buy in the supermarket.)
A lot of great research on wild pollinators and agroecosystems has been published this year. In particular, the pollinator conservation literature seems to be moving on from simple abundance/richness comparisons to other ecological contexts that are potentially more relevant to policy and management decisions, such as nutritional and commercial qualities of insect-pollinated fruits.
Below is nice round list of four articles published this year that got me excited. All four are ‘firsts’ for their particular topics and use great study design and insight to lead current knowledge on the subject matter gently in a new direction. They are also pertinent reading as we balance on the cusp of the UN’s international years of Family Farming and Soils.
Stone walls are central to the rich cultural heritage of human history. Some of the oldest stone walls in the world still stand in ancient Mediterranean lands, and also provide the foundations for Incan architecture (think Macchu Picchu) and the castles and ramparts of feudal Japan. In the UK, Ireland and Europe, stone walls are key elements of pastoral landscapes from a thousand postcards, and numerous regional specialities maintain their own unique cultural and ecological foundations. This colonial heritage is also preserved in the new world, particularly North America’s New England region and Australia’s southern states.
Stone walling is more than simply stacking rocks. A harmonious balance of art and science are needed to keep the wall standing. Each stone is fitted into the negative space around its neighbouring stones, like a jigsaw, so that the final wall holds itself against the pull of gravity. Continue reading →
There has been a flurry of excitement in the media over a recently-published observational study describing the “behavioural flexibility and adaptation” of solitary bees to our “plastic-rich environments”. In a nutshell, during the course of a larger field study looking at wild bees in urban landscapes, researchers in Toronto discovered that some urban Megachile bee species in the city had lined their nest cells with plastic materials.

A few weeks ago, my postgrad colleagues and I started a student research blog called Sturt’s Notebook, which will be managed and written by research students in our department. Here’s a guest post I wrote about the British Ecological Society’s collection of “100 of the most influential papers in ecology”. Even if you’re not an ecologist, it’s an interesting collection that provides much food for thought…including how omnipresent Ecology truly is, which I have written about here before.
So have a look at the “influential papers” and keep an eye on Sturt’s Notebook if you’re interested in new environmental research!
Their wide application, persistence in soil and water and potential for uptake by succeeding crops and wild plants make neonicotinoids bioavailable to pollinators in sublethal concentrations for most of the year.
Not only is this great news for bees, it also shows how imperative it is for governments and regulatory bodies to understand and critically assess ALL the evidence before implementing policy decisions.
[Odysseus] never closed his eyes, but kept them fixed on the Pleiades, on late-setting Bootes, and on the Bear – which men also call the Wain, and which turns round and round where it is, facing Orion, and alone never dipping into the stream of Oceanus – for Calypso had told him to keep this to his left.

Celestial navigation is as old as the stars (I apologise, I couldn’t resist the pun!). The night sky was used as a navigation tool long before compasses were invented, and it helped most of the ancient explorers gad about the globe without maps. Even today, anyone who doesn’t trust Apple Maps knows how to orient themselves using Polaris in the northern hemisphere and the Southern Cross in the south.
But, like a lot of things we think we’re pretty good at, animals figured it out long before we did. Quite a few interesting experiments have shown that birds or animals can navigate using the stars and now, the dung beetle has become the first insect proven to navigate by the stars (although, maybe the ancient Egyptians already knew this when they elevated the dung-rolling scarab to sacred status?).
Mistletoe has fascinated me since I was a child. At first, its charm was purely mythological – I spent many years obsessing over the European Christmas traditions I was missing out on by having a midsummer yuletide in subtropical Australia. Mistletoe, holly wreaths, snow angels, and warm eggnog – these things didn’t exist in my sweaty Queensland Christmases. It wasn’t until I was much older that I learned what a remarkable plant mistletoe is, and found out that it grew in Australia (as does holly, albeit as a weed!). I was beside myself. I still remember my excitement the first time I saw a mistletoe plant, flowing serenely off a eucalypt branch in the Bunya Mountains, like a leafy green waterfall suspended in mid-air.
