Insect Armageddon reprise

I was recently interviewed for a great new podcast on ABC called Science Friction by Natasha Mitchell. The episode is about insect declines, including the Insect Armageddon story I blogged about last year. Natasha also talks to two well-known Australian entomologists, Ary Hoffmann and Ken Walker, as well as Caspar Hallmann one of the authors of the German insect decline study. It’s really nicely produced and explores more than just the decline issue, showcasing how wonderfully unique insects are and why we need to spend more time getting to know them!

Limitations of using Altmetrics in impact analysis

The number of published papers using Altmetrics ‘attention scores’ as a data source to measure impact is rising. According to Google Scholar, there are over 28,000 papers mentioning Altmetrics and impact.

This latest analysis published in PeerJ finds a positive correlation between citation rates and the Altmetric score for papers published in ecology & conservation journals over a 10 year period (2005-2015). This implies: the more a paper gets tweeted, blogged, or talked about in online popular media, the more it will be cited.

This seems commonsense. The more exposure a paper gets online, compared to traditional exposure via journal alerts to the limited number of subscribers, the more people will be aware of it and potentially cite it. This is why we do scicomm. (Although, hopefully people read a paper first and decide on its quality and relevance before citing.) Continue reading

Ecosystem services or Nature’s contributions to people?

IPBES has released media summaries of their reports on global land degradation and restoration, and regional biodiversity and ecosystem services assessments. The results of these reports are really important.

Anyone who has been working in this area for the last couple of decades might have noticed that the reports refer to ‘nature’s contributions to people’ (NCP). Where did this term come from and what does it mean?

In a nutshell, it’s a new term for ‘ecosystem services’.

But do we need a new term? The term ‘ecosystem services’ was only established about 20-odd years ago (the concept is centuries’ older). I’ve been working on ecosystem services research for just over 10 years, and NCP came out of the blue for me. I heard about it a few months ago (just before the IPBES reports had been finalised), when a paper was published in Science by a group of well-respected scientists in the ecosystem services field who were involved in the IPBES assessments. Some related papers were published (here and here) in another journal, Current Opinion in Environmental Sustainability. Continue reading

Flower Visitors vs. Pollinators: no evidence that honey bees are the most important pollinator worldwide

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

Blogging for the science community

I’m very excited to present a new paper on blogging that is a direct result of me blogging! The paper is co-authored with some of the awesome ecology bloggers I have been following for years.

I’m proud to fly the flag for the southern-hemisphere blogosphere. Social media are dominated by the northern hemisphere, particularly North America. The timezone effect and geographical silos have a strong effect on how academics interact via social media, and southern hemisphere perspectives can be easily overlooked. Yet, compared to the northern hemisphere, the southern hemisphere has more countries, plenty of unique ecosystems and wildlife, and quite different higher education and academic systems! So I really hope this paper inspires more southern hemisphere ecologists to engage with blogs. Continue reading

Do scientists need Twitter verification to be credible?

A recent blog post by Andrew Kurjata asks some questions that many people have considered. Why does Twitter’s explanation of the sort of people who can be ‘verified’ not include scientists or knowledge brokers? Are politicians, singers and actors more worthy of public interest than scientists? No, of course they’re not. So why are we putting so much faith in the blue tick in the first place?

When I joined Twitter a few years ago individuals couldn’t ask to be verified. Instead, Twitter would “reach out” to eligible accounts when the time was right. I distinctly remember the words used. How snobby, I thought. The implicit assumption was that “reaching out” would occur when the account was deemed famous enough.

Now, the policy has changed, probably because Twitter employees got sick of spending all day reaching out to famous people on Twitter. Now anyone can ask for a blue tick of approval (but not everyone gets it).

Does this change the distribution of people that get verified? As with most awards and honours, women, minorities, or introverts are less likely to self-nominate for prestige, even if they righteously deserve it. Continue reading

Why repetition is good for science

‘Avoid repetition’. Most scientists had this command drummed into their heads early in their career. Science writing should be devoid of repetitive words and sentences. I had to include a preface in my PhD thesis to warn examiners of impending repetition…because my thesis chapters were published/submitted studies from the same system and with somewhat similar sampling methods.

Sure, thoughtless repetition of words and sentences does not make enjoyable reading in any discipline. But repetition of ideas and concepts is essential to storytelling and building memories. So when it comes to science communication, repetition is key. Continue reading
