My new paper has just been published in Insect Conservation & Diversity.
This has been the most enjoyable paper I’ve worked on, and I’m so excited it’s now online! It’s a systematic review of observations published in peer-reviewed literature of bee and syrphid fly species collecting pollen from wind-pollinated plants. I also cite some blog posts (see my previous post on this relationship) and discuss the importance of natural history.
The paper’s had a long development process (I presented some preliminary results at the Ecological Society of Australia conference last year) and a thorough peer review (3 revisions, 9 lots of comments and I think at least 6 individual reviewers) – thank you to Insect Conservation & Diversity and my wonderful reviewers for being so patient and helpful!
My review covered 1364 plant genera in 50 families. I looked at bee and syrphid fly species, because these are the most common pollinators in most environments globally. So this is not an ‘end of the road’ list; it’s a means to highlight how little we know about the ecology and life history of most insect pollinator species. Pollination systems of so many plant species are still undescribed, and life histories of so many insect pollinator species are still unknown…lots more basic natural history research is needed!

Long-time readers of my blog know that I think natural history notes are one of the most important parts of the scientific literature! Sadly, very few journals will publish them.
Luckily the Ecological Society of America does appreciate the value of natural history observations. I first submitted this note to Frontiers in Ecology and Environment for their Natural History Notes series. Unfortunately, the Frontiers series was about to close and they weren’t taking any submissions. But the editor suggested I submit my note to Ecology, where they were just about to start a new series called The Scientific Naturalist. So here it is.
Unfortunately it’s not open access and doesn’t have an abstract. So I’ve written a shorter note about my short note below; please email me if you’d like a copy of the original. Continue reading
When we think about planting for pollinators, the first plants we reach for are often ones with obvious flowers, usually bright and showy, perhaps with an attractive scent, and lots of pollen and nectar. Most of these will be insect-pollinated plants, which is why they are so attractive to pollinator insects – they have co-evolved with pollinators to reap the reproductive benefits of insect visitation.
But pollinators also use plenty of other plants that we wouldn’t think of as being ‘pollinator plants’, particularly plants that are pollinated by wind, like conifers and grasses. Some grasses are pollinated by bees. And some bees feed on fungi. These interactions have been observed by scientists and naturalists for centuries, but are often forgotten when we talk about pollinator conservation.
This is one of the key challenges with the ecosystem services concept. Trying to justify conservation of pollinator insects because they provide us with benefits, i.e. fruits and seeds from plants they pollinate, is not always useful. Partly because this approach overlooks the fact that pollinators also need lots of other resources to survive, some of which we may not benefit from. And separating ‘insect-pollinated crops’ (e.g. almonds, stonefruit, berries) from ‘wind-pollinated crops’ (e.g. wheat, rice, corn) when we talk about managing farms for pollinator conservation, ignores the fact that some pollinators will regularly visit wind-pollinated crops to collect pollen for food.
I’m currently writing a review of records of pollinator species visiting plant species that we traditionally assume to be wind-pollinated, after noticing some of these interactions at field sites and in my own garden (stay tuned!). I didn’t find any records of some of these plant-pollinator interactions in my literature review, so I’m recording them here. One-off ecological observations are rarely accepted by academic journals, because they are not considered scientific studies. But, in conjunction with other knowledge, they can provide important information for future research hypotheses.
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.
