Insect pollinators visit wind-pollinated plants too

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!

A failed experiment: earwigs as pests and predators in fruit orchards

Field ecology experiments are fickle. Even with best laid plans in place, they can fail…Nature doesn’t follow sampling protocols.

When this happens, should you publish the results? Most people would say no, and I would generally agree. Failed experiments are different to negative results. The latter are important additions to the scientific literature, but the former have very limited use. The results of failed experiments will have limited value, depending on why the experiment failed and how many data points were left intact. But they can have some use as ‘what not to do’ baselines for other researchers. Continue reading

Bees and breaking buds

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

Artificial pollinators are cool, but not the solution

Agreed, bees and other insect pollinators are under threat globally from multiple human pressures. If pollinators disappear completely from an ecosystem, their loss will affect the structure of those ecosystems and the natural foods and fibres we use from the ecosystem. So, finding solutions to the problem of pollinator decline are imperative.

This is why the robo bees story sounds like such a seductive idea. Imagine creating tiny drones with hairs on them that can be programmed to do a bee’s job? Wow! We are off the hook. Continue reading

Postdoc In Transit

I am currently in academic limbo.

My contract position as a postdoc at Charles Sturt University ended in December, after 3 years as a postdoc researcher and 3.5 years as a PhD student before that. At the beginning of March, I’ll be starting an exciting 3-year postdoctoral fellowship at the University of New England in Armidale, working with Romina Rader, Darren Ryder and Oscar Cacho.

I’ve found the transition period between postdocs challenging for a few practical reasons. It’s not as simple as clocking off at one job, handing your pass in and turning up to the new place. And while there is lots of good advice online about starting a postdoc for the first time (e.g Margaret Kosmala’s Advice for New Postdocs and Natalie Matosin’s Postdoc-ing for Dummies), I couldn’t find many tips on navigating the no man’s land between two postdocs at different institutions. But do read Amy Parachnowitsch’s great post on being ‘an unemployed academic’!

These are some of my experiences as an early career field ecologist in transit. Continue reading

Unlikely plant-pollinator relationships

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.
