These solutions all sound pretty sexy. But reducing the environmental impact of food production is not as simple as choosing one crop or livestock type over another.
Food production is a social-ecological system. That means it’s a system based on a mutual relationship between nature and humans. The ecosystem (i.e. the farm) influences human lives and actions, via ecosystem services. And humans influence the ecosystem’s structure and function, through direct management and indirect drivers like regulations, subsidies, financial markets and consumer demand. Continue reading →
Robert Patterson (1802-1872) was a remarkable naturalist you’ve probably never heard of. At the age of 19, he co-founded the Belfast Natural History Society. He also wrote a number of zoology texts and designed a series of zoological diagrams for use in schools. In 1857, he posted a ‘real Irish Rabbit’ across the Irish Sea to Charles Darwin, at Darwin’s request.
Patterson was also a bit of a Shakespearean. In 1838, he published a little book called ‘Letters on the Natural History of the Insects Mentioned in Shakspeare’s Plays.’
The book consists of 12 papers that were read out on ‘Public Nights’ held at the Belfast Society’s museum during the 1830s. These public events were common at learned societies of the time. For one night, the doors were opened to non-members to listen to the experts talk science (or literature, or whatever the society scholars were into). Clearly ‘science communication’ was just part of the job in those days. Continue reading →
Have you heard of urn heath (Melichrus urceolatus)? I hadn’t, until July last year. It grows along most of Australia’s east coast, but only in Box–Gum Grassy Woodland ecosystems (update: also in other ecosystems! see Greg Steenbeeke’s comment below). For most of the year, it’s an unassuming, prickly little shrub, usually less than 1 metre in height. Then in late winter, it bursts into a mass of tiny creamy-white urn-shaped blooms. Each individual flower is only a couple of mm in size. But a shrub in full bloom will stop you in your tracks.
This is what happened last July, as I took my regular afternoon walk through a local urban nature reserve. The reserve (Eastern Hill in Albury, NSW) is a tiny fragment of the Box-Gum Grassy Woodlands that were once common across the region. Continue reading →
Agricultural research and management programs often deal with these interactions by focusing on simplistic “good” and “bad” labels: aphids are annoying pests, for example, whereas bees are little angels.
The Internet is no longer a space for readers to simply consume content passively, it’s now a place where readers can actively engage with content and its author. Social media, in particular, are based on content sharing and discussion.
As a medium, blogs are different to news, books or academic literature. They are community-focused…but the content acts as a go-between for author–audience interactions, rather than a quod scripsi, scripsi contribution from the author. For bloggers, having a social media presence and not engaging with your social network is like going to a dinner party and sitting in the corner all night with your back to everyone.
Here’s an engagement tip not often mentioned in the ‘how to blog’ guides. Sharing other people’s posts is a positive and effective way to expand your network. So what are the best ways to share other people’s content without losing your own individual voice? Continue reading →
Every year, I get to share my birthday with these guys:
I’ve been mildly obsessed with both of them for years, for obvious reasons. But it was only recently that I discovered their early contributions to the land-sharing/land-sparing debate, something directly relevant to my own work. Darwin’s ecological legacy is well-known, but how often do we consider Lincoln’s impact on environmental history? Continue reading →
Critical analysis skills are a key survival skill, but facts-on-demand has taken over in many modern educational structures. And despite the best intentions, the ‘openness’ of the internet has simply confused things. Opinions on scientific issues regularly rub shoulders with evidence and sometimes it can be hard to tell which is which (for scientists and non-scientists alike).
And what is ‘scientific evidence’ anyway? I wrote about this a few years ago, but it’s much more complex than I had room to explain.
I recently stumbled across this great series on how to evaluate scientific publications, from the German peer-reviewed medical magazine Deustches Ärtzeblatt. The papers are useful for teaching, for critical news audiences, and for practicing scientists. All articles are open access, translated from German. The series started in 2009 – I haven’t found a contents list or an apparent end-date for the series, so I will keep this updated as they get published. Continue reading →
