I am currently advertising a PhD position! Do you want to understand why meerkat groups engage in vicious intergroup battles? What are the consequences of these skirmishes? What are the best strategies? Can we understand warfare in our own species by studying collective violence in other social mammals? If this sounds interesting, please visit this link to learn more and apply.

The deadline is the 8th January 2025, and the position will start in October 2025. 

I am so so happy to share that I've started a new post as a Research Lecturer in Ecology and Conservation at the University of East Anglia. More research in social behaviour, cooperation, health & meerkats to come!

At a recent ASAB Virtual conference, I gave a 'notebook talk'. It was the most popular and talked-about presentation I've ever given. I thought I'd share some advice and tech tips for those wishing to create a similar talk. Click the image below to learn how to make and stream your own notebook presentation!

I'm delighted to reveal my new Wildlife Photography website. Wildlife photography has been my passion for over twenty years, and I'm thrilled to be able to share some of my favourite shots.

​​During WW2, several Pacific Islands suddenly gained great strategic value to both the Allies and Japan. These forces quickly attempted to establish island military bases. The communities that inhabited these islands suddenly experienced technology hundreds or even thousands of years more advanced than their own. Cargo planes and airdropped crates brought hundreds of tons of manufactured clothes, tinned food, tents, medicine, guns, tobacco, soap etc. These goods were intended to help the war effort, but they quickly found their way to the local communities, who often assisted troops by acting as hosts or guides. It must have been an inconceivable bonanza.

Then, the war ended. The troops left and took almost everything with them. As quickly as the local people had lurched forward millennia, they lurched back again, but this time they knew what they were missing. In an attempt to summon more of the beloved goods, the communities re-created the conditions and peculiar rituals which led to the arrival of the bountiful cargo. They cut landing strips through the forest. They built planes and radar towers out of hay, and re-enacted military drills and marches. Generations later, improvised air-traffic controllers wearing coconut headphones still diligently signalled which runways were clear for landing.

​No planes came, and the well-meaning efforts were in vain. The older generation had accidentally bumbled into unimaginable progress and prosperity. Through no fault of their own, the younger generations never had any hopes of equality, and their attempts at replicating the good fortunes of their fathers and grandfathers were hopelessly misguided and doomed to failure.

This is how it feels to be an unestablished academic today, and to hear the stories of those who secured lectureships in decades gone by.

I recently read David Eagleman's Sum, which is a collection of imagined after-lives. It is a work of "philoso-fiction", written in the hope that thinking about what happens after we die might help us think about all the things that happen before we die. You can find the full text for free here. This post is about the first chapter, which is less than 400 words long.

In chapter one, your after-life is a replay of your first life, with one change. Your life's events are shuffled into a new order, with all the moments that share a quality grouped together. You drive and drive, only reaching your destination after 18 months. You spend a full thirty years asleep. Seven hours endlessly vomiting, two days tying your shoelaces. You shower for 200 days, do laundry for three months, and drink for 45 days, laugh for a week, fall over for 25 minutes.

And then, for three minutes, you read a little book chapter about an alternative life. A life where activities are split into tiny enjoyable pieces. You do something until you're tired of it, and then do something else. You eat when you're hungry and stop when you're full. You can blissfully switch between events and do whatever takes your fancy, whatever excites you. You hop between activities so frequently you never tire of doing anything. For three minutes you ponder this infinite luxury.

At its best, an academic research job in evolutionary biology is similar to this joyous patchwork. We think about ideas, read others' work, write code for analysis, plan experiments, peer-review submissions, produce presentations, buy equipment, collect data, write manuscripts, give seminars, meet colleagues, attend conferences, write press releases etc. Sometimes we do all of these, in as little as a week or two!

Doing any of these things non-stop for more than a few weeks would quickly become unbearable. But switching between them is endlessly stimulating. I frequently feel jaded and depressed about the state of academic science, and my place in it. But it's worth remembering how good it is when it works. We're privileged to enjoy, as Eagleman puts it, "the joy of jumping from one activity to the next like a child hopping from spot to spot on the burning sand."

... in meerkats, at least.

Our new study has been published in Current Biology. (Click here for links to free PDFs of all my publications).

This study was unusual because I embarked on it expecting a negative finding. For several years, some researchers studying highly social mammals had been strongly suggesting that dominant individuals in animal societies had special delayed ageing rates. We've known for a long time that dominant individuals tend to live longer than their subordinate counterparts, but do they have slowed ageing? If they do - billions should be spent studying them to unlock the secrets of staving off inevitable age-related declines in health. But do they?

I suspected not. Slowed ageing rates that are somehow activated when an animal becomes dominant require some acrobatic physiology and evolutionary biology to explain. There is likely a simpler explanation. But with an open mind I set out to find out why dominants live longer, using the Kalahari Meerkats. For nearly two years we blood-sampled 35 meerkats repeatedly, to assess individual ageing rates. To do this, we analysed their blood telomeres, which are a genetic marker of cellular wear-and-tear that accumulates with ageing. 

The data revealed that, as expected, dominant meerkats outlived subordinates. However, we found that dominants' ageing rates were not slowed, but accelerated, compared to subordinates. Reproduction and status defence was taking its toll on the dominants' cells.

So how do fast-ageing dominants outlive subordinates? We looked at other differences between these classes. For decades, scientists have followed the soap-opera dramas of meerkat day-to-day life. One frequent dramatic event is the disappearance of subordinates. Low-ranking females are violently kicked out of the group by the dominant female, and low-ranking males voluntarily trot off in search of mating opportunities, with both sexes usually returning after a few days. By contrast, dominants of both sexes never leave the group. We found that these trips away from the group were extremely dangerous, and solo subordinates were at risk of starving or feeding a nearby bird of prey. Dominants meanwhile enjoy the safety of the meerkat pack.

In short, dominants' lives aren't extended - subordinate lives are curtailed. Subordinates are not able to reproduce within their own group, so they are forced to leave the group and brave the dangerous Kalahari alone. Many do not survive. Those that do later become dominant themselves, and now have the good sense to never leave their group again.

As a reward for reading this far, why not have a look at my Lego Summary of the paper in this Twitter thread?

Peer review is important. Like a guard by the gates to the garden of enlightenment, it ensures that only worthy pieces of scientific literature are widely disseminated. It blocks misleading, mistaken and down-right dangerous papers from gaining traction, affecting public opinion, shaping policy and wreaking havoc. Usually, anyway.

But peer review is complicated. I've only been reviewing for a few years, and have only reviewed 12 papers, so I can't claim to be the world's foremost reviewer of biology manuscripts. What I can provide are the fresh (naive) thoughts of an early career researcher (ECR) and relative newcomer to the reviewing game. I've identified two main problems with writing and receiving peer reviews, and done my best to come up with solutions, after discussion with other ECRs (most notably Alecia Carter and Corina Logan).

PROBLEM 1: Receiving peer reviews can be the most unpleasant piece of text you will read about yourself and your work, ever. Peer reviews rarely congratulate you for good ideas, hard work and gutsy attitude. Instead, they savagely highlight all the flaws. They can be rude, thoughtless and occasionally wrong, and are not a nice final step in the long journey towards a piece of scientific literature.

SOLUTION: I sign all my reviews. Most reviewers don't want to be unpleasant, yet the cloak of anonymity means lapses into clumsy, cruel criticism do not have consequences. By signing all my reviews, I cannot accidentally write something unnecessarily harsh. I cannot forget to congratulate the authors for their hard work, and wish them luck with their paper (whatever the outcome). Instead, I write thoughtful, helpful, constructive reviews, even when I think the paper is garbage.

This is usually very easy - most papers I review are good quality, and for the rest I don't feel that deciding to reject (albeit politely and helpfully) would bite me in the ass later in my career. Even in the worst-case-scenario (rejecting a paper from a rival lab) the decision to sign has not only been without cost, it has had huge benefits! I've been approached at conferences and workshops, and thanked for my helpful comments. I've been congratulated on the decision to sign reviews. The reviews I've signed have started chats about science that would otherwise never have happened. 

I STRONGLY encourage everyone to sign all their reviews, except where doing so would be life-threatening or completely career-ending.

PROBLEM 2: Writing a helpful, constructive review (which you will have to do, if you are signing it!) is hard work for no money. 

SOLUTION: I only review for journals I consider 'ethical.' If I am donating my time and expertise, I need to ensure that the recipient is deserving! Journals that are for-profit, remove money from academia and are not open-access (or charge extortionate OA fees) clearly do not deserve charity from me.

When I receive a request to review from an 'unethical' journal, I accept. I then immediately return a blank review, with a confidential note to the editor explaining my decision. For 'ethical' journals, I also include a confidential note, congratulating them on their policies and explaining my decision to review for them.

As well as giving me the warm feeling that I'm contributing my time and brain to a worthy cause, this has the added benefit of screwing up and delaying the review process for 'unethical' journals. Don't feel too sorry for them: these journals charge authors publication fees, and then charge readers to access the papers. And most of the money is removed from academia. Why not use that money to pay for conferences, or grants, or studentships? Perhaps a clunky, delayed review process might encourage these journals to change their policies, or even encourage authors not to submit there anymore.

So in summary: sign all your reviews, and don't do unpaid work for the bad guys. Simple.

And as a reward for reading this far, here is a picture of a baby elephant shortly after crossing a river with its mother. Remember: the same task may be more challenging for some individuals than others. And it is not their fault.
