I haven’t written for The Conversation (TC) for a while, and this article was a new experience for me: a commission via Twitter! A TC editor saw a live tweet from a talk I gave at a conference in April (where I mentioned that Australian almond growers rent honey bee hives to pollinate blossoms), and contacted me to write a story elaborating on the theme.
My most-cited paper so far (although not really the most-cited when you take years of publication into account) is an entomological field methods paper. It was also an unplanned paper. It came out of my PhD data, but wasn’t one of my research questions.
Methods papers are great contributions to the literature, and I highly recommend PhD students consider writing one, especially if they are working on understudied systems, or find some interesting patterns during data collection. Methods papers have much broader application to diverse fields and sub-disciplines than the PhD results themselves might. Continue reading
Rolling plains of wheat, endless fields of flowering canola, row upon row of fruit trees: these agricultural landscapes are the stuff of stunning photographs.
Filling these paddocks with just one crop, known as monoculture, is a relatively easy, common and efficient way to produce food and fibre.
But international research shows that these monocultures can be bad for the environment and production through effects on soil quality, erosion, plants and animals, and ultimately declining crop yields. Research I have published this week in the International Journal of Agricultural Sustainability shows a possible link between monoculture landscapes and fewer wild pollinators.
Is there a better way to grow our food?
Serious about saving the bees? Time to rethink agriculture.
There is much more to saving the bees than spring flowers and a golden mascot….
The concept of the ‘edge effect’ has inspired long and varied discussion in the ecological literature. In essence, an edge effect is a change in animal or plant communities seen at a boundary between two types of habitat.
These changes are most obvious in plant communities, for example where a swamp segues into a savannah. So, historically, research into edge effects and ecotones (the zone surrounding the edge where two plant communities meet, and energy fluxes and dynamics change) was mostly focused on plants.
It wasn’t until the mid-1900s that people started considering how edges affected animals. Vegetation ecologists had already discovered that the zone surrounding habitat edges usually had more plant species than either of the two patches that met at the edge.
Then in 1930 Aldo Leopold noticed that game animals, like deer, were often found more frequently at forest edges than in the interior. These animals loitered at edges, where they could feed on all the extra plants and see danger coming more easily. And so the misconception arose that edges = more animals. Continue reading
Wild pollinator insects, especially bees, like diversity in their life. It’s not that they’re fussy, they just like to have different resources for nesting and foraging to choose from – just like us. This diversity in resources is important because wild pollinator communities aren’t just made up of bees, they include multiple species. We’ve (almost) figured out what honeybees like, and it’s easy to accommodate one species when you know the ins and outs of their biology. But ‘wild pollinators’ could mean solitary bees, bumblebees, huge hairy flies, delicate wasps, tiny midges, thrips, beetles, bugs, weevils, moths or butterflies. Some of these insects, particularly wasps and flies, may also control outbreaks of herbivorous insects, so they can provide multiple ecosystem services. Continue reading
