Literature reviews summarise existing knowledge and emerging paths for inquiry. They are essential for most grant applications, undergrad assignments and research projects.
But how do you actually do one? And what should you expect when you read a literature review?
Recently, I’m seeing a lot of papers submitted to or published in reputable journals that claim to be “comprehensive reviews” when they could not be further from the truth. Flawed review methods, no review methods, or a limited/localised observational study dressed up as a global review…. 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
This is a guest post from Matthew Holden, an applied mathematician based at the University of Queensland. I loved seeing his backyard biodiversity hunt on Twitter, because so many of his pictures were of invertebrates! His story…
Well that’s what I wanted to know about my home.
It all started one day, more than a year ago, when my housemate, Dr Andrew Rogers, was cleaning out his closet. He wanted to move the spiders outside and spare them from getting sucked up by our vacuum, during a much-needed cleaning session. But there was one problem, there were a lot of spiders, definitely several species. He thought, “How many spiders do I share the house with?” It was a slippery slope … it wasn’t long till we wanted to know all of the species in our home.
From then on, we regularly talked about conducting a very local biodiversity survey, but never got around to it. We were fortunate enough to even have a taxonomist, Dr Russell Yong, move in with us, who was keen to help out. But we kept putting it off.
Then the pandemic happened. We all decided to start working for home – a perfect time to do the survey. It would give us all a social activity to bond over during this time of isolation. Andrew even came up with a hashtag for us to share our findings #StayHomeBiodiversityChallenge. 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
This week I had a bittersweet achievement. I started a great new job, moved in to my beautiful new office, and then immediately moved home to work for the foreseeable future, amid the simmering anxiety of this global pandemic.
Readers who follow my blog know that I moved to Armidale three years ago to start a postdoctoral fellowship at University of New England. Before that, I was at Charles Sturt Uni in Albury, where I did my PhD followed by my first three-year postdoc.
This week I started as a Lecturer in Ecology & Biology at UNE. The position was advertised in November last year; I applied, interviewed and found out I was successful a few weeks ago. I’m so excited!
But it’s a really strange time to be starting a new job – my thrill at joining the teaching team has understandably been overshadowed by the ongoing stresses of COVID19. 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
