Godfrey Hewitt Mobility Award
Godfrey M. Hewitt (1940-2013) was President of the European Society for Evolutionary Biology (ESEB) from 1999-2001. He was exceptionally influential in evolutionary biology both through his research and through his mentoring of young scientists. He was also a great believer in seeing organisms in their environment first-hand and in exchanges of ideas between labs. Therefore, ESEB has decided to offer, annually, mobility grants for young scientists in his name.
More information about Godfrey M. Hewitt is available at the University of East Anglia, at Wikipedia, and at the Evolution Tree – The Academic Genealogy of Evolutionary Biology.
Call for Applications
The next call for applications will be announced in automn 2016 at this website.
The award is open to PhD students or postdoctoral scientists who are, at the closing date for applications, both within 6 years of the start date of their PhD and ESEB members. The maximum single award will be 2000 Euros. It must be used to support fieldwork or a period of research at a lab that you have not previously visited. There is no restriction on the country of residence or nationality of the applicant. A report will be required after one year, by which time the funds must have been used.
Your application should be sent as a single PDF file to Ute Friedrich at the ESEB office, firstname.lastname@example.org. It should include your name, current status and institution, your PhD start date, your ESEB membership number, a description of the work to be carried out (maximum 500 words), an outline budget with brief justification (maximum 100 words) and a signed statement from your PhD supervisor or postdoctoral adviser (maximum 100 words) explaining why the work cannot be funded from your home institution or your proposed host institution.
Applications will be considered by a committee chaired by Roger Butlin. The aim will be to announce decisions before the end of March 2016.
The committee will consider the following key criteria:
1. The value of the proposed mobility in terms of its expected output and impact on the applicant’s career. The committee prefers projects that are:
- Not a core component of the applicant’s existing PhD or postdoctoral project, but a new venture.
- Clearly based on the applicant’s own initiative
- Likely to be completed and have definable output within the award period
- Have the potential to lead to larger future projects or to enhance the applicant’s career in evolutionary biology
2. The need for the GHM award, i.e. the potential for the funding provided by ESEB to make a difference, in relation to resources already available through the home or host institution.
Please endeavour to address these points in your application.

Evolution of temperature-dependent sex determination in reptiles
Applicant: Thomas Merkling, Australian National University, Canberra, Australia
Funding provided: € 900
Sex allocation is a field I am very interested in and one the remaining mystery is how and why transitions between genotypic and environmental sex determination occur. The Godfrey Hewitt mobility award allowed me to visit Dr. Lisa Schwanz for 10 days at the University of New South Wales to collaborate on a theoretical model aiming to fill this gap. The idea of the model is that if juvenile survival to maturity is influenced by temperature and if males and females mature at different ages, then temperature-dependent sex determination (a form of environmental sex determination) should be selected for. The aim of my visit was to build a dataset compiling data on sex-determining mechanisms and sex-specific age at maturity of lizards, snakes, crocodiles and tuataras to add to the turtle data already collected by Dr. Schwanz and her colleagues. We then used phylogenetic generalised least square models to test for a relationship between sex-determination mechanisms and difference in age at maturity in these groups, but unfortunately the results did not corroborate the predictions of the model.

Genomic imprinting of soldier-activity loci in polyembryonic parasitoid wasps
Applicant: Petri Rautiala, University of Jyväskylä, Jyväskylä, Finland
Funding provided: € 1100
The Godfrey Hewitt Mobility Award allowed me to visit Dr. Andy Gardner at the University of St Andrews to construct a mathematical model to investigate the function of the “soldier”-caste of certain polyembryonic parasitoid wasps. Whether the soldiers are there to protect their brothers and sisters, or that they actually kill their brothers to make room for their sisters, has been a source of controversy for over a century. We found that the competing hypotheses make different predications about patterns of gene expression. These contrasting predictions point to a possible resolution of the controversy of the soldiers’ function, and could also help researchers discover new genes for soldiering, by looking at the expression patterns for candidate genes, and see which ones are deactivated according to their parent of origin. The study, “Intragenomic conflict over soldier allocation in polyembryonic parasitoid wasps”, was accepted to be published in the April 2016 issue of The American Naturalist.
Grubs of doubt: The impact of stem-borers on Mercurialis annua life-history traits
Applicant: Luka Rubinjoni, University of Belgrade, Belgrade, Serbia
Funding provided: € 1750
Thanks to ESEB’s Godfrey Hewitt Mobility award, I was able to conduct a field survey in Spain during the spring of 2015, and a research visit to Prof. John Pannell’s lab at University of Lausanne, Switzerland. I studied the impact of Kalcapion semivitattum (Apionidae), a monophagous folivore with stem-boring larvae, on life-history traits of Mercurialis anuua (Euphorbiaceae), an annual herb with different ploidy levels (from diploid, to hexaploid) and reproductive systems (monoecy, androdioecy, dioecy) across its range. In order to explore the potential role of herbivore specialists in plant reproductive system evolution, I searched for differences in infestation intensity among the plant genders, in natural and experimental conditions. I also looked for evidence of insect specialization to different ploidy levels, and its potential role in contact zone shift and diploid range expansion. The samples were collected across the monecious hexaploid / dioecious diploid contact zone, along the Mediterranean coast, from Barcelona to Valencia. Plants were measured and dissected, and leaf samples were preserved by fast drying in silica gel. Grubs were counted and preserved in alcohol, along with collected adults. In Lausanne, local insects were successfully reared on both diploid and hexaploid plants. A phylogeographic study K. semivittatum across the range of M. annua is in preparation.
Are males and females equally honest? Insights on the determinants of sexual ornaments in a sexually monomorphic bird species: the king penguin (Aptenodytes patagonicus)
Applicant: Quentin Schull, University of Strasbourg, Strasbourg, France
Funding provided: € 1750
When assessing mate or competitor condition, animals often rely on ornamental signals that are costly to produce and/or maintain, thus natural selection is expected to favour the evolution of sexual ornaments that honestly reflect individual quality. Whereas ornaments are known to reflect physiological/social quality of the bearer and be implicated in both male and female king penguin pairing decisions, we lack knowledge on how physiological status during moult, the time these ornaments are renewed, may determine their showy nature. The Godfrey Hewitt Mobility Award allowed me to work under the supervision of Dr Pierre Bize from the University of Aberdeen. By experimentally increasing Corticosterone basal level and stimulating the immune system during moult we highlight that some ornamental features appear more intrinsically linked to genetic individual quality whereas others are determined by individual’s physiological status at the time of the moult.
Showing off in birds: is cooperativeness a mating signal? Experimental study manipulating the audience in the Sociable weavers, Philetairus socius
Applicant: Arnaud Tognetti, Institute for Advanced Study, Toulouse, France
Funding provided: € 1950
Cooperative behaviours provide benefits to the recipients but are costly to the actor. Cooperative behaviours can only be selected if costs of cooperation are compensated by fitness benefits. These benefits can be either direct or indirect. However, the importance of sexual benefits has been overlooked in non-human species. In collaboration with the Sociable Weaver Research Project lead by Dr. Rita Covas (CIBIO-Portugal & FitzPatrick Institute-South Africa) and Dr. Claire Doutrelant (CNRS-France), I proposed to examine the role of sexual selection in the evolution of cooperation in this cooperatively breeding passerine. I wanted to investigate whether helpers would increase their nestlings provisioning when playbacks of female songs are broadcasted. With the Godfrey Hewitt Mobility Award, I bought the materials needed to conduct field experiments in South Africa. Unfortunately, El Niño phenomenon caused intense drought in Africa that impacted drastically the weavers’ reproduction and prevented me from conducting my experiment. Nonetheless, I initiated a collaboration with Dr. Fanny Rybak (University ParisSud, France), a specialist in acoustic communication, which allowed me to prepared playbacks and performed pilot experiments testing the feasibility of the experiment. I also recorded males and females songs to increase the number of playbacks I will be able to use during the experiment next year. These songs are currently analysed acoustically and show interesting sex differences.
