Birds, bees and bugs: your garden is an ecosystem, and it needs looking after.
This piece is part of a great series on The Conversation about the science behind gardening. My article focuses on gardens as wildlife-friendly habitat, particularly for pollinators. Also check out the other articles in the series!

A key argument against the ecosystem services concept is that it doesn’t account for most of the ecological complexity around us. This is a valid criticism. The ecosystem services concept is based on an idealised economic stock–flow model, which is pretty simplistic and unrealistic when you apply it to a real social-ecological system (i.e. any system based on human and nature interactions).
Identifying a particular ecological process as a ‘service’ because it benefits humans in one time and place overlooks the principles of basic ecology: outcomes of interactions between species and environments change across space and time.
Recently, some scientists have argued that quantifying ecosystem disservices is the best way to account for this complexity. Disservices are essentially the opposite of services, outcomes of natural processes that affect humans negatively, like disease spread, or pest damage to crops.
But this could be just another wild goose chase. Continue reading
Last spring, I found a new bee in a tiny urban reserve near my house in Albury. I identified it to genus Megachile, but that was as far as I got. I had never seen anything like it. After some research, and help from local bee enthusiast Karen Retra, we identified it as Megachile semiluctuosa.
I submitted my sighting to the Atlas of Living Australia (ALA), which is the main online, publicly-available database of Australian biodiversity records. My sighting was the first record of M. luctuosa for the Albury region – the nearest recorded sighting was about 200 km north of here.
Yes, I got a bit excited. But this is more likely an indication that few people are out looking for bees, rather than evidence of range expansion. ALA has records of this species from across most Australian states, but nearly 70% of them are from central New South Wales, mostly from a research project conducted by CSIRO researchers.

Two long-term studies were published today showing comprehensive evidence that neonicotinoid use could have long-term effects on populations of non-target insects, especially wild pollinators. The studies look at wild bees in the UK and butterflies in California.
I wrote a piece for The Conversation on why I think these studies are important and how these results relate to Australia.

‘Scientists shouldn’t have to do scicomm’ is a thoroughly modern misperception.
Communicating science has been ‘normal’ for centuries, from painted messages on cave walls, to classical orators and beyond. From ancient times, scientists took their responsibility to share science with people very seriously.
Yet today, mastery of language and the art of non-scientific communication are rarely taught or encouraged in modern science degrees. History isn’t taught much either.
Instead, many science students and graduates train to be skilled data collectors and ‘facts’ wranglers. Scientists are consistently bombarded with rigid anti-eloquence ‘rules’ that only succeed in suppressing the power of language – never use passive voice, don’t use big words, shorten your sentences, simplify your message etc. etc. God forbid you should sound like you care about your subject matter.

Save the bees. Bees are in danger. Bees are dying. Bees are an endangered species.
It’s great that popular media are turning attention toward pollinators, albeit with slightly exaggerated style.
But how damaging are sloppy grammatical errors and misleading ‘facts’? Continue reading
The latest edition of Wildlife Australia magazine is out, including an article I wrote on unusual plant-pollinator relationships from Australian ecosystems. I had so much fun writing this piece about Australia’s unique flora and fauna. From nectar-loving lizards to hairy katydids, there are lots of interesting ecological stories out there to discover!
You can download a pdf of the article here. If you enjoyed this story and want to read more like it, I recommend subscribing to Wildlife Australia, one of the best nature magazines still printing.
