Red Listing the amphibians of southern Africa - again

10 April 2024

The first GAA3 meeting for Red Listing the amphibians of southern African 

The first Global Amphibian Assessment (GAA) took place in various workshops around the world from 1999 to 2002. I got involved by helping to assess the South African pipids while at University of the Western Cape (Measey 2004), and later at a workshop in Watamu, Kenya in April 2002.

I hosted the first re-assessment of South African amphibians in 2009, a process that incorporated the published strategy for conservation research on southern African amphibians. Together with other members of the workshop, we turned the results of this meeting into a book, which I edited, and was published by SANBI in early 2011. The book is available as a free pdf to download, and you can get your own copy here

We repeated the Red Listing process again in November 2015 (see here), and these results were carried into the second Global Amphibian Assessment (GAA2), one of the outputs of which was published last year (see here)

The assessments should be updated every five years, and so it was high time to do it again. This time we got together at the Calders Hotel in Fish Hoek.

It’s quite fun to see the faces in these images ageing. There are the loss of a few of the older faces too. But the really great thing was to see the large number of new faces who brought with them some excellent expertise that amazed me. The workshop was hosted by Josh Weeber and current southern African Amphibian Specialist Group Chair Jeanne Tarrant. This is the first workshop of the GAA3

Although we spent four days solidly assessing the amphibians, we didn’t finish. Lots more work to do before we can submit the updates and have them published on the Red List site. Stay tuned for this update.

Bullfrogs for sale

03 March 2024

American Bullfrogs, Lithobates catesbeiana for sale in supermarkets

I have long been fascinated by the behaviour of American bullfrogs, Lithobates catesbeiana, sold in supermarkets in China. Anyone familiar with these species in their native North America will know that they are easily spooked and quickly disappear at the first sign of movement by jumping into nearby water. Individuals in invasive populations are no different and this causes a lot of issues for those who attempt to control their numbers, as I found out when I was hunting them in San Diego (see here).

Even invasive populations in China act just the same and are very flighty. But the animals that you see in the supermarket are completely sedate, not jumping at all. Usually, these animals are sold in plastic string bags, and they seem to sit very quietly. Nothing like what I’d imagine if I put wild-caught animals into a bag.

But in a supermarket in Kunming, I came across bullfrogs in a wide-open container with a very low wall that all of them were capable of jumping out of. They were not restricted in any way, yet they just sat and I did not see any individuals moving.

What other behaviours have changed for these farmed animals? Are there many other traits of domestication? Are these same domestication traits shared by the turtles in the adjacent tank?

There are some great questions to investigate with these frogs, especially as there are many local invasive populations to sample nearby.

Visiting Macquarie University

20 February 2024

A talk for the School of Natural Sciences at Macquarie University

As I was already in Australia and had to fly back via Sydney, I decided that I’d take a stopover on the way back and visit colleagues at the Department of Biological Sciences at Macquarie University. There are a number of notable researchers there including Martin Whiting (previously of Wits University in South Africa), Georgia Ward-Fear (with whom I had written a book chapter but never met) and Rick Shine (he of the snake and cane toad fame).

There is another important connection. Martin was the former PhD supervisor of James Baxter-Gilbert, who went on to become my post-doc in Stellenbosch University. http://john.measey.com/People/Measey-Lab-Alumni

I was very fortunate to be hosted by Martin at his home and to get to know his family and their adventures. Martin very kindly took me frogging on a wild and windy night and I got to see a few of the region’s amphibians (Adelaide was way too dry).

As well as having a great time catching up with new and old friends at Macquarie, I was able to give a talk for the School:

Time spent with the Cassey Lab in the University of Adelaide

21 January 2024

A month in the Cassey lat at the University of Adelaide

In January 2020, Phill Cassey invited me, Reid Tingley (Monash University) and Julie Lockwood (Rutgers University) to participate in an ARC Discovery grant application that he was submitting. The aim of the grant was to study the reptile trade in Australia and using past data make predictions on future trends. A large part of the data was set to acquire global data for traded reptiles to determine the demand for global species so that Australian taxa could be placed into context.

Looking back, January 2020 was just before the global pandemic, and none of us knew what was going to unfold over the coming two years. Happily, in November 2020 (despite the pandemic) the Discovery grant was funded and this included funding for a trip to Australia for me to dedicate some time to the project.

In November 2023, Phill reached out to me and reminded me that the project was soon to end and that I should either commit to visiting Australia or lose the opportunity. Happily, I was able to plan a trip in January 2024 that coincided with New Year holidays in China. And so it was that I spent a month working in the Cassey lab at the University of Adelaide.

First, I should say a big thank you to Phill Cassey and members of his lab for hosting me. It was a great experience (1) to spend some time in Australia (my first trip) and (2) to hang out with Phill’s dedicated team of reptile (and other) fundis. Special mention must go to Sebastian Chekunow, Adam Toomes, Jacob Maher and Jasmin Broadbridge - thank you for all your kindness.

In addition to lots of time spent in the office working hard on catching up with the reptile trade work that had already been done, I was able to find some time at weekends for getting out into the field seeing some native Australian reptiles. Especially important for me was the one pygopod that we managed to see.

I was especially pleased to have the opportunity to meet Emma Sherratt and talk caecilians with her.

Before I left, I gave a talk on my own research to the department in a departmental seminar.

Having a plan for your future

29 December 2023

 Make sure you have a plan

“The Cylons were created by man. They rebelled. They evolved. There are many copies. And they have a plan.”

Battlestar Galactica

Having a plan is an essential part of your PhD strategy. You might think of it as a shining star guiding your way through the dark times. Or, perhaps like me, you are prompted to remember the Cylons in the sci-fi series Battlestar Galactica. However it takes you, having a plan will hold you in good stead throughout your PhD as it will ensure that you have something beyond your PhD to focus on.

There is a temptation, once you have started and invested many years in academia, to simply fall into step and see where it leads you. This lack of a plan will see your life collapse around you once you finish your PhD and wonder what it was all for. Or, more likely, you will get part way through your PhD and start questioning exactly why it is taking up so much of your life.

This chapter aims to help you build a plan for your future career and aid you to see how you can improve your chances on reaching your goal.

What is a long-term plan?

A long-term plan sets a goal for you in 10-15 years from now. This is likely to be a career choice, like joining a particular business or having a position in a certain company. Beware of having a long-term plan to become an academic, as there may not be opportunities (see Part I). Equally, your long-term plan could be about the lifestyle you want to achieve in the long-term, or about where you want to be in the world. All of these are valid plans and they are totally up to you to envisage.

This may be the first time you are thinking about it, or you may have always known what your long-term plan was. In either case, once you have decided on your plan you next need to decide on medium- and short-term goals that will guide your decisions during your PhD years, and the moves that follow.

Long-term plans need medium- and short-term goals

You need to consider your three time periods:

  • Long-term (10 - 15 years)
  • Medium-term (5 years)
  • Short-term (2 years)

The first thing to realise when you are planning for your future is that long-term plans need action in the short- and medium-term. It is only by achieving these actions that will help you reach your long-term goal. Personally, I like the three time period idea as short-term plans might only include getting something ready for the medium-term, and not necessarily doing that action.

If you don’t like to think of specific time periods, you can think of the short-term as the time during your PhD. Medium-term is the years after your PhD and long-term is your career path. Short-term planning will consist not of having to find your primary occupation, but adding tools to your tool-box in order that you have a complete tool box for the long-term. Similarly, you can think of medium-term not as being employed in the actual job you want to do, but in a step along that particular career path.

Having a plan during your PhD is invaluable This diagram shows how your short-term plan is related to your medium-term planning, and how that will influence your long-term goals. In turn, your long-term plans will impact on what you do in the medium- and short-term.

This diagram shows how your short-term plan is related to your medium-term planning, and how that will influence your long-term goals. In turn, your long-term plans will impact on what you do in the medium- and short-term.


Teaching example

If your goal after completing your PhD includes teaching in secondary or tertiary education, you are going to want to make sure that you have teaching experience. Planning to have a teaching experience sufficient to put on your Curriculum Vitae (CV) in the next 2 years is probably unrealistic as you may well be in the midst of your PhD studies (obviously, in some institutions you may get immediate opportunities). But you can plan that within the coming two years you will know exactly when in the medium-term your teaching experience will happen. In turn, this will require that in the short-term you need to actively look for those opportunities.

Research example

If your goal after completing your PhD is for a career in research, then there are definitely steps that you can take in the short- and medium-term that will increase your chances of success. Most research positions require fundraising as a central component of, what is essentially, project work. This means that you will want to have experience of fund raising, probably through grant writing. You might not need to write a grant in the short-term, but you should be looking for opportunities of granting bodies to apply to, and projects that you have the capacity to undertake in the medium-term. Such projects might not be you on your own, but with other people in your group or institution, or connections in your network from another institution.

You will also want to look for opportunities to publish. Publishing your thesis chapters is likely to follow in the medium-term (i.e. once you’ve finished your thesis), but there are likely to be opportunities before this to start getting publications on your CV. Remember that these might not be research papers, but could be publishing a literature review or another type of paper (Measey, 2022).

Other additions to your CV

Teaching, grant writing and research papers are all solid items to add to your CV during your PhD studies, but you may want to consider having some additional items if these will be skills required in your long-term plans. For example, you may be interested in having experience in administration and management. It may well be that you can volunteer to fulfil these roles in your research group or department. For example, you may want to get elected into a student representative role and sit on the department’s management committee. Or it may be that someone has some administration exercise that you can help them with. You won’t know unless you ask.


Consider the letter of reference that your advisor will write

An important consideration for your medium-term plan is that you will likely be asking your advisor to write a letter of reference for you. In the short-term you can find out from people who already work in your long-term career choice what the ideal reference letter consists of. Once you know what is needed, you can in the short-term begin to make sure that you have all of these elements in place. For example, your advisor can’t write a letter of reference that says you have great organisational skills unless you have helped them with organising something. If, like me, you have a bad memory for things that you have done, you will also need to write down these activities and examples of when you did them so that you can remind your advisor when the time comes for them to write a letter of reference.

Advisors are busy people, and they don’t always notice all of the different things that you are doing. So make sure that you remind them what you have achieved during your time with them, especially when it comes to writing that letter of reference. Don’t rely on them to remember!

Changing your long-term plans

Don’t worry about changing your long-term plans. Life often happens, and you may want or have to change your plans. In the short-term, changing long-term plans is easy. You should realise that the further you go down a particular career path, the more difficult it becomes to make long-term changes. However, if you do, then it is not impossible, and will need you to make some short-term plans in order to make those changes.

The other book has advice for getting a job inside academia, as it also does for leaving academia for a job outside (Measey, 2022).

Share your plans

Don’t forget to tell the people around you of your plans for the future. Remember that they may know about opportunities that they can only pass onto you if they know what your plans are. They may also be able to provide you with specific advice about exactly what experience you need.

Having a plan is probably one of the most valuable assets that you can hold throughout your PhD days. If you have read all of this and still don’t know what yours is, then I’d suggest that you start to think about this now, and don’t push it into the future when not having a plan is going to be increasingly problematic.
