Here I show there is no evidence that this is worldwide phenomenon, with data from the southern hemisphere (n = 1).Continue reading
It’s increasingly common to see universities publishing press releases about newly published papers from academics. This practice emerged a few decades ago and originally seemed to be associated with health and medical research (educated guess, not sure there are any data on this).
But it has since spread more widely to many other disciplines. Ecology journals are now doing it; some ask you to submit a mandatory media summary with your manuscript ‘just in case’ (most authors will never get a media request). Some of the Big Famous journals operate on a strict authoritarian embargo system, to ensure the author doesn’t exercise their right to talk to people about their own research.Continue reading
Comments aren’t allowed on the Thesis Whisperer blog, so I’m writing here. I really think these posts send negative messaging to prospective (and current) PhDs. Do read the original posts, but here’s a quick summary of how I interpreted the Thesis Whisperer’s argument:
(i) the way we do PhDs needs to change;
(ii) we should galvanise PhD students to go against the norms of academia to get the personal outcome they want.
(iii) academic writing is ritualised and archaic and it “sucks”.
From a distance, this general argument might resonate. Yes, as with most sectors, there are many ways the past is holding academia back.
I agree, PhD students need to make sure they get what they need out of the 3 or more years they spend on the PhD.
But PhDs are definitely still “a degree worth having”. They will always provide the opportunity for graduates to develop a unique set of skills and expertise that are useful for academic and non-academic careers.Continue reading
Just published in Journal of Applied Ecology: Conceptual ambiguity hinders measurement and management of ecosystem disservices.
Ecosystem services is one of the most misunderstood scientific concepts. Ambiguity and confusion can be a real barrier to establishing a new scientific concept or field of research. Ecosystem services is still a young discipline (formalised in the 1990s based on a much longer heritage) and is often misrepresented as being a purely economic concept that is damaging to biodiversity conservation and ecological science. This couldn’t be further from the truth, yet this misguided opinion consistently gets regular airtime and clouds broader understanding of the relevance of ecosystem services to research, policy, and land management.
The term ecosystem disservices was first used to address an early criticism of the ES concept, i.e. that ES was largely focused on benefits and overlooked the ecological reality that nature sometimes harms us. This is a valid issue that must be addressed in any ES approach. But, as we argued a few years’ ago, creating a false dichotomy around opposing terms is not the most effective way to solve this problem.Continue reading
The concept of citizen science is as old as the hills, but large-scale coordinated projects are growing in popularity, especially those with digital engagement tools. It’s always great to see new projects that fill an important knowledge gap and engage the public with the natural world.
Recording biodiversity sightings is an easy and rewarding way to get involved. There are plenty of opportunities to contribute to coordinated data collections, such as iNaturalist or Atlas of Living Australia. Other projects have more standardised scientific goals, such as the UK’s Pollinator Monitoring Scheme, the USA’s Great Sunflower Project, and our own Australian Wild Pollinator Count (disclaimer: this is my own project).
So what about new projects that overlap existing projects and don’t provide clear information about how the data will be used? Continue reading
With urban areas around the world suddenly emptied of humans, people are sharing photos and videos on social media showing wild animals cavorting in the empty streets.
I started to collate some of them on Twitter, but I gave up because it’s really hard to confirm how many of them are fake news.
The Goats of Llandudno were a legitimate lockdown observation – but it turns out they’re regular visitors to the town. Some posts are clearly a joke (a herd of buffalo in the centre of Buffalo, NY), while others would seem pretty believable to most people with no specialist knowledge of the species or location, like the ‘rare Malabar civet’ in the streets of an Indian town.
Most posts provide very little context, no confirmation of the date they were filmed, and often no confirmed source. For the average responsible social media user, there is simply no way of verifying them. Continue reading
The latest issue of Insect Conservation & Diversity is out, a special issue on insect population trends. I’m really happy I was able to contribute to a few papers in this issue as both editor and author (obviously not the same papers in each case!).
Thanks to Editor in Chief Raphael Didham for pulling together a great collection of papers, as well as rallying the editorial team to contribute to the issue with this really useful peer-reviewed paper summarising the key challenges involved in measuring insect population trends. This paper is really timely, as it highlights some of the potential pitfalls involved in estimating population changes over time.
Ecological data (e.g. long-term data on animal population trends) are not like simplified stock market trends or sports team stats. They are confounded by numerous complex environmental and measurement factors, many of which an observer may not be aware of. Nature isn’t simple and we’re kidding ourselves if we want a quick and easy answer to sum up everything, everywhere. Continue reading
A couple of years ago I wrote about some of the limitations of relying on Altmetrics as an indicator of a paper’s impact, because it doesn’t pick up all online mentions.
Yes, impact metrics are flawed; experts have been pointing this out for years. And I’m not singling out Altmetrics here, there are a few different impact metrics used by different journals for the same goal, e.g. PlumX, Dimensions, CrossRef Event Data.
Despite their flaws, we’re all still using them to demonstrate how our work is reaching global audiences. I used them recently in a promotion application and a major grant application.
But I’m now questioning whether I will keep using them, because they are deeply flawed and are consistently misused and misinterpreted. They are literally a measure of quantity without any context: the number of shares or mentions, but no indication of how and why they are being shared.
This is problematic for a few reasons. Continue reading
This magic number was stated in that flawed entomofauna paper, without any explanation of how this number was calculated – see why that paper is flawed here.
Since then, it has been stated regularly in popular media, scientific papers and technical reports, often without citation, just a number pulled out of the air and presented as fact.
Globally, there are about 5 million estimated insect species in total. Only 1 million species have scientific names. So, conservatively, the 40% claim suggests that at least 400,000 species are threatened with extinction.
So is it an accurate prediction? No. Here’s why: Continue reading
We summarise the major flaws in the pop culture ‘insect apocalypse’ narrative and argue that focusing on a hyped global apocalypse narrative distracts us from the more important insect conservation issues that we can tackle right now. Promoting this narrative as fact also sends the wrong message about how science works, and could have huge impacts on public understanding of science.
And, frankly, it’s just depressing. Right now, we all need hope, optimism and reasons to act, not a reason to give up.
