Evidence-based Half Earth

The argument that half our planet should be set aside for Nature has been in the news lately. A few years’ ago, E.O. Wilson wrote Half-Earth, his plan to save the biosphere by dedicating half the planet’s surface to nature. Other scientists have published supporting arguments, for example here and here.

The idea is commendable and inspiring. Modern human civilisation is having huge, sometimes irreversible, effects on natural processes and ecosystem function. In return, the outcomes of these effects are having terrible impacts on human wellbeing, e.g. climate change, loss of natural vegetation, plastic and agrichemical pollution etc.

To sustain life, we (all of us) really need to change the way we use our local and global environments.

So is the ‘half earth’ proposal realistic and effective for achieving this goal? Continue reading

Entomologising

I recently discovered this gorgeous book, loaned to me by a colleague (Elizabeth Hale, who blogs over at Antipodean Odyssey).

These days, children’s books and popular media often portray insects as scary creepy-crawlies, and the decline in outdoor play and education means many kids rarely encounter an insect that’s not a household pest.

Back in Victorian times, before screentime entertainment, things were a bit different. Victorian entomologists wrote widely on the wonders of insects, from their roles in Shakespeare’s plays to the ecosystem services they provide. Continue reading

Sugar teaspoons for bees and science communication

Fakenewsflash: the recent Facebook post claiming to be from David Attenborough, suggesting that we should feed floundering bees a sugar solution to ‘save’ them, was faked.

I’m not on Facebook, but I saw the original post via Twitter, where many popular non-profit and government organisations promoted it (it now seems that many have deleted their posts).

I didn’t know it was a fake post at the time, but I didn’t agree with it so didn’t share it or comment on it. I didn’t want to be the Grinch that disagreed with the popular personality. And perhaps the pollinator message would reach a new audience, despite the fake news…

But what price new audiences? Continue reading

How do you review a conceptual paper?

Scientific disciplines grow from new concepts, ideas, theories and expert opinions, not just data. But conceptual papers are the hardest kind of scientific paper to publish.

Too many researchers…seem to think that any non-empirical paper is simply an essay and devoid of deeper scholarship. Nothing could be further from the truth. More than once I have received comments from reviewers claiming a paper is nothing more than an essay, implying essays are little more than opinions. But aren’t all papers “opinions” in one form or another?

~ Rudy Hirschheim (2008)

By definition, a conceptual paper doesn’t present original data…but it must present an original concept. It synthesises knowledge from previous work on a particular topic, and presents it in a new context to provide a springboard for new research that will fill knowledge gaps.

Conceptual papers shouldn’t follow the status quo; they need to show how moving beyond the current norm will enhance knowledge. Continue reading

Bumblebees are frequent flyers – what are the impacts?

The Applied Ecologist's Blog

Addressing pollinator introduction policy and the effects introduced species can have on local ecosystems, Romina Rader, Manu Saunders and Tobias Smith discuss the recent Policy Direction, Coordinated species importation policies are needed to reduce serious invasions globally: The case of alien bumblebees in South America by Aizen et al.

Bombus Photo by A. Saez

Bumblebees (Bombus spp.) are large, iconic pollinators of many wild flowers and crops.  Their ability to buzz-pollinate flowers with poricidal anthers and their ease of husbandry has led to the domestication of several species as managed pollinators, particularly Bombus terrestris, a native to Europe.  In many countries, bumblebee colonies are now mass-produced to pollinate a range of different crops in greenhouses, polytunnels and open fields, with an estimatedannual value of €55 million. The recent Policy Direction by Aizen et al.  investigates the consequences of this rapid expansion by reviewing the current…

The Importance of Surveying Pollinators Across Various Environmental Conditions

This is a guest post by Emma Goodwin, a UNE honours student I’m co-supervising with Romina Rader and Francisco Encinas-Viso at CSIRO. Emma spent a few weeks over summer in Kosciuszko National Park, catching pollinators and collecting data on alpine plant-pollinator networks, and is currently writing up her exciting results! This blog is co-posted over at the Rader Lab website.

Recent plant-pollinator network studies have been concerned with the impacts that climate change may have on pollination across various ecosystems, particularly in alpine regions. Many of these studies are investigating ‘phenological mismatch’ as a significant issue that may result from climate change.

‘Phenological mismatch’ or ‘phenological asynchrony’ is used to refer to when the emergence of pollinators and flowering time of plants becomes out of sync over time. If these two processes become out of sync then it reduces the potential for flowering plants to be pollinated. Continue reading
