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

Raptors provide an important ecosystem service by scavenging carcasses in agricultural landscapes

This post is from my PhD student Rebecca Peisley, who I co-supervised with Gary Luck. Rebecca submitted her thesis earlier this year. Find the paper here: The role of avian scavengers in the breakdown of carcasses in pastoral landscapes.  Also read Rebecca’s previous post on her other PhD work in apple orchards here.


Animal carcasses such as deceased livestock, road-kill or culled animals are a fact of life in agricultural landscapes, and can encourage increased and unwanted visits from wild dogs and foxes and also contribute to the spread of disease. Scavenging birds in these landscapes can remove carcasses, and therefore provide an important ecosystem service for farmers.

Perhaps the most well-known examples of carcass removal services in agricultural landscapes, which are worth millions of dollars each year, are those provided by vultures in Europe, Asia and Africa. The removal of carcasses by vultures near human settlements can reduce the number and visitation rates of rabid dogs that would otherwise be attracted to the carcasses, and in so doing, reduce the spread of rabies to the human population.

Unfortunately, vulture populations have suffered severe declines in recent years, and do not occur worldwide. However, other bird groups such as raptors and corvids are also common scavengers and a diverse assemblage of these occur in Australia. Like vultures, the scavenging behaviour of raptors and corvids has the potential to reduce the prevalence of unwanted pests such as red foxes and wild dogs in the landscape, and also reduce the spread of diseases such as blowfly strike. However, the benefits of carcass removal in agroecosystems in Australia are not widely recognised and have not yet been quantified. Continue reading

A failed experiment: earwigs as pests and predators in fruit orchards

Field ecology experiments are fickle. Even with best laid plans in place, they can fail…Nature doesn’t follow sampling protocols.

When this happens, should you publish the results? Most people would say no, and I would generally agree. Failed experiments are different to negative results. The latter are important additions to the scientific literature, but the former have very limited use. The results of failed experiments will have limited value, depending on why the experiment failed and how many data points were left intact. But they can have some use as ‘what not to do’ baselines for other researchers. Continue reading

The unpublished results taboo

Late last year, I retweeted a university press release about some topical research on bees that hadn’t yet been published or, apparently, peer reviewed (I can’t find the paper online anywhere, so it looks like it is still yet to be published).

To be fair, the release stated upfront that the research was ‘preliminary findings’ and the source mentioned at the end was an upcoming conference presentation, not a journal article. But should it have been the subject of a press release in the first place? Continue reading

Bees and breaking buds

Long-time readers of my blog know that I think natural history notes are one of the most important parts of the scientific literature! Sadly, very few journals will publish them.

Luckily the Ecological Society of America does appreciate the value of natural history observations. I first submitted this note to Frontiers in Ecology and Environment for their  Natural History Notes series. Unfortunately, the Frontiers series was about to close and they weren’t taking any submissions. But the editor suggested I submit my note to Ecology, where they were just about to start a new series called The Scientific Naturalist. So here it is.

Unfortunately it’s not open access and doesn’t have an abstract. So I’ve written a shorter note about my short note below; please email me if you’d like a copy of the original. Continue reading

The benefits of pre-submission peer review

I’ve noticed that acknowledgements sections in papers published before the 2000s usually thank people who read and commented on the paper before it was published. Yet recently-published papers are more likely to thank funding bodies or data collectors than peer reviewers. Why is this?

Google Scholar is an awesome research tool

As undergraduate students, most researchers are taught to use their university library’s journal databases for researching assignments, projects and papers. The best database for your needs varies by discipline, because most cover a subset of ALL academic journals based on disciplinary area.

Journal databases are great, and I strongly recommend researchers talk to their library liaison person to work out the best databases to use for their research. Seriously, librarians are awesome and know things about research tools that many academics don’t.

But sometimes journal databases don’t cut the mustard. I’ve become quite a fan of Google Scholar for a few reasons. GScholar is not just another professional social media for researchers; it’s a complementary research tool with huge benefits. Continue reading
