The new term brings new group members! A new PhD Student, Juan Enciso, will shortly be arriving to join us from Colombia. There are 2 new Masters students, Liam Moffat, who is doing an MRes, and Jenni Smith, who is in the 4th year of an MBiolSci and spent the summer helping Gabby with her research in Ecuador.
We also have 3 undergraduates doing their research projects in the lab: Emma Hazelwood, Fern Wilkinson and Hannah Bainbridge. I am also very grateful to 2 undergraduate students who have volunteered to help look after our butterfly stocks: Sophie Smith and Jess Eaton-Fearne.
Here is a video I made to demonstrate structural colour. The blue colour on these butterflies’ wings is produced when light passes through nano-metre scale structures and the interfaces between these and the surrounding air. When ethanol is dropped onto the wings these air spaces are filled in and so the colour changes. The video is at 2x actual speed, so you can see that the colour comes back when the ethanol evaporates.
Congratulations to the students who graduated on Monday! In particular to Anna Puttick and Thomas Gomersall who did their Masters projects in my lab, and to Beth Moore and Will Wood, who did their honours projects in my lab on colour preference and foraging behaviour in butterflies. Beth is going on to do a PhD and Will is starting a Masters next year! Good luck in your future endeavours!
There is currently an open call for Marie Skłodowska-Curie Individual Fellowships (Deadline 14th September 2017). Please get in touch with Nicola if you are interested in applying for one of these to come and join the group. Eligible candidates are post-doctoral researchers wanting to move to the UK from another country (either inside or outside Europe). I would be particularly interested in post-docs with experience in evolutionary developmental biology who are interested in working on structural colour, but feel free to get in touch if you have any interests that you feel overlap with mine.
We will taking part in Discovery Night in the Department of Animal and Pant Sciences, part of the Sheffield Festival of Science and Engineering, on Friday 10th of March from 4-8pm. We will have live butterflies and be explaining how they can help us to understand diversity in tropical rain forests. Recommended for all ages 5+ !
I am currently advertising for a PhD student with interests in evolution and behaviour to work on a project investigating the role of iridescent structural colour in predator avoidance and mate choice in Heliconius butterflies, co-supervised by Mike Speed, Institute of Integrative Biology, Liverpool.
The bright wing colours of these butterflies act as warnings to predators and mimicry between species facilitates predator learning and reduces attack rates. Wing colours are also used for mate choice and attraction. The main colours used are red, yellow and black, due to pigments, but a small number of species also exhibit iridescent blue/green, due to sub-micron scale structures. The role of these colours in deterring predators and attracting mates is less well understood. The project can be tailored to the interests of the student but would likely involve experiments using captive butterfly populations in South/Central America and the UK, and could involve experiments with wild or captive avian predators or theoretical modelling. The project would also tie in with ongoing work on the genetic basis of these traits.
If successful, the student would be fully funded for a minimum of 3.5 years, studentships cover: (i) a tax-free stipend at the standard Research Council rate (at least £14,296 per annum for 2017-2018), (ii) research costs, and (iii) tuition fees at the UK/EU rate. Studentship(s) are available to UK and EU students who meet the UK residency requirements. Students from EU countries who do not meet residency requirements may still be eligible for a fees-only award.
This PhD project is part of the NERC funded Doctoral Training Partnership “ACCE” (Adapting to the Challenges of a Changing Environment). This is a partnership between the Universities of Sheffield, Liverpool, York and the Centre for Ecology and Hydrology. Further information and details of how to apply are here. The closing date is the 9th of January 2017. Interested candidates are also welcome to contact me for further information.
Selection process: Shortlisting will take place as soon as possible after the closing date and may involve an informal interview. The shortlisted applicant will be notified promptly and invited for a formal interview to take place at the University of Sheffield the w/c 13th February 2017.
A warm welcome to the new students joining the lab. Anna Puttick and Thomas Gomersall will be doing their 4th year MBiolSci projects in the lab and Beth Moore, Grace Holland and William Wood are doing their 3rd year undergraduate research projects. Also welcome to Fern Wilkinson, a 2nd year student, who is going to be helping to maintain our butterfly stocks. Thanks Fern!
Thanks to everyone who came to the Heliconius meeting! There were 53 participants in the end (including 3 from Montpellier, who didn’t make it in person because of the strikes, but had a virtual presence through the wonders of teleconferencing). This included representatives from 16 different research organisations spanning 7 countries. It was great to hear about all the work that is going on, across quite a diversity of topics. Download the programme (without last-minute changes) and abstracts if you missed the talks or want to refresh your memory.
Congratulations to the student talk prize winners:
1st Bruna Cama (University of York) – Genetic analysis of wing pattern and pheromone composition in two sister species of Heliconius butterflies
2nd Paul Jay (CNRS, Montpellier) – Supergene evolution favoured by the introgression of an inversion in Heliconius
The Sheffield weather didn’t do us any favours, but that didn’t stop us sitting out in the beer garden of the Fat Cat on the last night.
