Insect declines: pay attention

Last year I wrote about the Insect Armageddon story – an important paper that received some exaggerated media hype.

A new paper just published in PNAS adds another twist to the insect declines saga…clearly, this story is far from over.

Lister & Garcia analysed data collected in the Luqillo Experimental Forest in Puerto Rico. This area of tropical rainforest is not a ‘pristine’ untouched wilderness, as some media reports are claiming – no place on Earth is untouched by humans! The site has been a long-term research location for decades, going back to the early 1900s, with a focus on experiments to understand the effects of disturbances of all kinds. Many important experimental research projects involving human disturbances (like this one) have happened in the Luqillo forest.

This study is important for a few reasons. Continue reading

How to choose a framing narrative for scientific papers

Have you read a research paper where you experience this sequence of thoughts?: Title/Abstract/Introduction (wow! This is a real problem, someone’s finally answered this question), Methods (um, hang on, this sample size/study system/analysis approach doesn’t quite answer this problem…), Results (okay, these results are interesting, but…), Discussion (whoa, rein it in! I can’t find the link between these assumptions or recommendations and the results…).

The paper may be scientifically sound, as far as the methods & results go. The problem is that the authors have chosen a very broad frame narrative, and then confounded that frame with the interpretation of their results. Continue reading

Sugar teaspoons for bees and science communication

Fakenewsflash: the recent Facebook post claiming to be from David Attenborough, suggesting that we should feed floundering bees a sugar solution to ‘save’ them, was faked.

I’m not on Facebook, but I saw the original post via Twitter, where many popular non-profit and government organisations promoted it (it now seems that many have deleted their posts).

I didn’t know it was a fake post at the time, but I didn’t agree with it so didn’t share it or comment on it. I didn’t want to be the Grinch that disagreed with the popular personality. And perhaps the pollinator message would reach a new audience, despite the fake news…

But what price new audiences? Continue reading

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!

You can listen to the Insect Armageddon story here, or subscribe to Science Friction through your favourite apps.

 

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
