Hybridisation or not - that is the question

24 April 2017

To hybridise or not?

Here's another interesting take on the continuing saga of hybridisation between the invasive Xenopus laevis and Endangered Xenopus gilli

We found no evidence of hybridisation between these species, despite finding many F1 hybrids in the past. This suggests some post-zygotic isolation happening in the hybrid zones. These days, that's just about everywhere for X. gilli .

Ben Evans visit to the CIB in June 2015 kick started this work. Ben received a CIB fellowship. You could apply too...

I was lucky enough to visit Ben's lab in March 2017.

Lead author Solveig Vogt visited the MeaseyLab in 2014 when she spent 3 months sampling the frogs with MSc student Andre de Villiers. Other authors, Dennis and Flora helped Solveig finish off the work when she got back to Germany.

Some familiar faces from the MeaseyLab in France

Giovanni Vimercati, Natasha Kruger join Jean Secondi in Angers this April. Natasha is starting her PhD project jointly at Stellenbosch and Lyon 1, and Giovanni is finishing up his post-doc in Stellenbosch and settling into his new post-doc working on invasive Xenopus laevis  in France.

University of Hull visit to eDNA experts

18 March 2017

Talking at the School of Environmental Sciences, University of Hull

It was great to see Dr Katharina Wollenberg Valero agian and catch up with her in her new post at the University of Hull. We teamed up with Prof Lori Lawson Handley to conduct an eDNA investigation.

I gave a talk to the joint lab meeting on our work on invasive frogs in South Africa.

Far far away in a snowy backwater

02 March 2017

It's warm inside, but outside it's freezing - literally

I'm very luckky to be spending some time in the Evans Lab this March, with my first experience of a -10 C cycle ride in Canada today. We're working up the next gen sequencing data generated last year for investigating hybridisation of Xenopus laevis and Xenopus gilli

Ben visited the MeaseyLab back in June 2015, when he delivered a workshop on next gen sequencing analysis. Ben's work at McMaster University, Hamilton Ontario, has already included processing of lots of next gen datasets. Handling all the data is quite a task!
