Pollination is a complex process. It’s not as easy as an insect simply visiting a flower.
This is important to remember when talking about which species are the ‘best’ or ‘most important’ pollinators. Simply observing an animal visiting a flower is not, on its own, evidence that the animal is pollinating the flower.
Many insects (and other animals) visit flowers, to feed on pollen, nectar or other flower parts. Many of these interactions result in pollination…although some visitors are better pollinators than others. Some of these visitors commit floral larceny – they are robbers or thieves (there’s a difference!) of either pollen or nectar, and they leave without pollinating. Some might even damage flower parts so much that they indirectly affect the flower’s capacity to be pollinated by other visitors.
To know for sure that an insect is pollinating a particular flower, we first need to know what kind of reproductive system that flower has. Is it male, female or bisexual (containing both male and female parts)? Can it self-pollinate, or does it need to be outcrossed to another flower or plant of the same species? Once we know this, we then need to watch the behaviour of the insect that visits that flower. Does the insect visit one flower and fly away, or many flowers in a row? Does it move between plants? Does it actually touch the reproductive parts of the flower when it visits each flower? Continue reading
A few years ago, I wrote an article for Ensia about how popular media tend to separate science and nature stories as if they’re unrelated categories. Most major online news websites have separate pages for ‘Science’ stories (predominantly technology, space and medical research) and ‘Environment’ stories (mostly pieces on nature, wilderness, environmental activism, or cute wildlife, sometimes with a few pieces on climate change thrown in for good measure).

The cultural traditions of Christmas, like every aspect of our lives, are embedded in stories of science…botany, ecology, chemistry, entomology etc. If you blog about science and nature, Christmas-themed posts can easily become an annual habit.
Unfortunately, because of our distracted relationship with the internet, many timeless Christmas posts are read once and discarded, just like the wrapping paper and festive napkins at the end of the big day.
So here are a few Christmas posts from the archives that you may have overlooked, or might just enjoy reading again! Continue reading
The number of authors included on research papers in many disciplines has increased over time. This editorial in Journal of Applied Ecology is the latest analysis of this trend, finding that published single-author research papers in that journal have declined since 1966 (two years after the journal started publishing). N.B. the authors only quantify research papers (i.e. data papers, but they don’t specify if they include reviews/meta-analyses…see below), and applied ecology should be a multidisciplinary field, so this is a good thing.
The editorial is excellent, and you should read it – the discussion of underlying causes of this trend is mostly reasons why we should encourage more multi-author papers.
But…there will always be a place for single-author papers in research, especially for early career researchers. Continue reading
Leading on from the ‘buzz’ of our recent paper on science community blogging, here is a nice Q&A from my university’s media team (thank you UNE!) about how I started blogging and why I love it. If you’re thinking about blogging, but not sure where it will take you, I hope this gives you some insight!

This is a guest post from a colleague, Neil Taylor, who is Professor of Science Education at UNE. We hear a lot about predatory journals from an author’s perspective. But I found this combination of editorial & author experience interesting.
The International Journal of Environmental and Science Education (IJESE) began in 2006 under the editorship of Dr Huseyin Bağ of Pamuakkle University, Turkey. I was asked to be on the editorial board and for a number of years I reviewed for the journal, published some articles in and co-edited a Special Issue on Scientific Literacy in 2009. After 2012 when I published my final article in IJESE, I lost touch with the journal and received no further requests to review. However, at the beginning of 2017 I wrote an article about a school gardening project in Oman that seemed to be a good fit for the readership of IJESE. As is often the case these days, as part of the submission process I was asked to provide the names and contact details of three potential reviewers. About six weeks after submission, I received notification from the editor that the article had been accepted without revisions. This was surprising but I was busy at the time (and perhaps a little vain), and given that IJESE was a reputable journal – I just accepted this outcome. Good quality galley proofs subsequently arrived and all requested changes were made efficiently and the article was published on the IJESE website. Continue reading
Sustainable agriculture is an ambiguous term. Because ‘sustainable’ simply means ‘maintained at the current level’, sustainable agriculture can be whatever you want it to be. It’s used more than it probably should be in scientific and political documents, because it’s a broad encompassing term that most people have heard. But it needs to be interpreted within the context it’s referring to, not on its own. Sometimes that context isn’t clear.
Modern agriculture is a leading driver of our current environmental problems, already pushing us beyond the safe limits of most planetary boundaries. But not all agriculture is equal. Very few studies, or their associated news stories, clarify the subtle social and ecological differences between individual farms and landscapes.
