How many species live in your home?

This is a guest post from Matthew Holden, an applied mathematician based at the University of Queensland. I loved seeing his backyard biodiversity hunt on Twitter, because so many of his pictures were of invertebrates! His story…

Well that’s what I wanted to know about my home.

It all started one day, more than a year ago, when my housemate, Dr Andrew Rogers, was cleaning out his closet. He wanted to move the spiders outside and spare them from getting sucked up by our vacuum, during a much-needed cleaning session. But there was one problem, there were a lot of spiders, definitely several species. He thought, “How many spiders do I share the house with?” It was a slippery slope … it wasn’t long till we wanted to know all of the species in our home.

From then on, we regularly talked about conducting a very local biodiversity survey, but never got around to it. We were fortunate enough to even have a taxonomist, Dr Russell Yong, move in with us, who was keen to help out. But we kept putting it off.

Then the pandemic happened. We all decided to start working for home – a perfect time to do the survey. It would give us all a social activity to bond over during this time of isolation. Andrew even came up with a hashtag for us to share our findings #StayHomeBiodiversityChallenge. Continue reading

Nature moves back in…or will it?

With urban areas around the world suddenly emptied of humans, people are sharing photos and videos on social media showing wild animals cavorting in the empty streets.

I started to collate some of them on Twitter, but I gave up because it’s really hard to confirm how many of them are fake news.

The Goats of Llandudno were a legitimate lockdown observation – but it turns out they’re regular visitors to the town. Some posts are clearly a joke (a herd of buffalo in the centre of Buffalo, NY), while others would seem pretty believable to most people with no specialist knowledge of the species or location, like the ‘rare Malabar civet’ in the streets of an Indian town.

Most posts provide very little context, no confirmation of the date they were filmed, and often no confirmed source. For the average responsible social media user, there is simply no way of verifying them. Continue reading

The Wilderness: Amy Eleanor Mack

Stories build a relationship between subject and audience that is deeply emotional and personal. Art can enhance the audience’s nature connection, and stories about natural systems and wildlife can determine how the reader connects with those systems. This is particularly true for children.

Australia has a wonderful heritage of nature writers, many working before nature writing was ‘a thing’. The national collection of Australian children’s books about native wildlife is inspiring. Even more inspiring, many of Australia’s best nature stories were written in the early-mid 19th century, and mostly by women.   Continue reading

10 minutes with Nature

(Or Ode to Ecology Part 2)

We have a cicada plague* at home. The house we rent is bordered on two sides by a tiny patch of remnant eucalypt woodland. It is infested with cicadas, which started singing here around September. At first it was an occasional chirp, almost unnoticeable. But the heat of the last few of weeks means the chorus has swelled. At peak cicada, we can no longer hear traffic on the Hume Freeway, about 300 metres away. Thankfully, cicada chatter is much less offensive to the ear…although some claim it can damage your hearing, and the cicada boom has unfortunately resulted in the disappearance of most of the birds we see very morning.

Plastic Bees

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.

Slow Food in the Fast Lane

Urban agriculture itself is not news, but the reviving interest in edible urban ecosystems is exciting, as it has the potential to change the way we relate to food, Nature and society. Community gardens, urban permaculture, edible landscapes, forest gardens, market gardens – label it however you like, it all boils down to people growing and harvesting their own food, instead of buying it from a ‘middle man’…which should come naturally to all of us!

Although many urban agriculture systems were developed to profit from the produce (e.g. through farmer’s markets or barter systems), there is increasing interest in more ‘passive’ urban food production – incorporating permanent food plants into urban planning schemes, and allowing the local community to reap the benefits at their leisure.
