    • Evolution of Sex and Asexual Reproduction One day meeting. Friday 5 September 2008 at the University of Bath, UK While the maintenance of sex and recombination remains an intellectual challenge, the long term persistence of some asexuals is equally puzzling. What if anything can be learnt about the former issues by studying the latter and vice versa? There are multiple contrasting approaches to these problems: theoretical versus empirical approaches, genetical verses ecological explanations, field versus laboratory systems. This meeting will bring together all of these strands in current research. Speakers: Scientific organisers: Christina Burch (North Carolina, USA) Laurence Hurst (Bath) and Roger Butlin (Sheffield) Jukka Jokela (Zurich, Switzerland) Peter Keightley (Edinburgh, UK) Featuring: Ryszard Korona (Krakow, Poland) 2008 Mendel Medal winner, Dunja Lamatsch (Mondsee, Austria) Matthew Meselson (Harvard, USA) Thomas Lenormand (Montpellier, France) Mike Lynch (Indiana, USA) 2008 Balfour Lecture by Stefan Scheu (Darmstadt, Germany) Daven Presgraves (Rochester, New York) Registration Fees: Genetics Society members £30, non-members (academic) £80, non-members (non-academic) £135 Student members can apply for travel grants to offset the cost of attending this meeting (see website for details). Visit the Genetics Society website for further details and to register for the meeting: www.genetics.org.uk/home.

    • A meeting of The Genetics Society The Mammalian Genetics and Development Workshop 20th - 21st November 2008 . Institute of Child Health, UCL, 30 Guilford Street, London WC1N 1EH The Mammalian Genetics and Development Workshop is a small annual meeting that aims to cover any aspects of the genetics and development of mammals. Meetings are based on the submitted abstracts, and usually include diverse topics ranging from early mammalian development (not exclusively human or mouse), imprinting and positional cloning of disease genes to human population genetics and association studies. In recent years, presentations on other model systems (such as chick and zebrafish) have also been included where these relate to general developmental questions or disease models. The meeting is traditionally a venue for post-docs and PhD students to talk rather than laboratory heads and so is an excellent training ground and friendly, informal forum for discussing new results. In keeping with this objective, we offer TWO PRIZES of £150 to individual post- graduate/post-doctoral presenters who, in the opinion of a panel of judges, have given an outstanding presentation. A further prize is also offered, thanks to the generosity of the editors of Mammalian Genome (Springer). The prizewinner receives £150, a book of choice from the Springer range plus a year's subscription to Mammalian Genome. One additional prize of £200 will be awarded to the speaker judged to have given the best presentation of a genetics-based research project. Promega, who will also sponsor the wine reception at this meeting, generously contributes this prize. Registration A £10 registration fee is payable by all attendees on arrival at the meeting. The fee entitles registrants to attend all of the scientific sessions, to receive the abstract booklet and tea/coffee refreshments on both days. Speakers and chairpersons will be provided with lunch, free of charge, on the day of their presentation. Other participants will be expected to make their own arrangements for lunch. All participants are responsible for organising their own overnight accommodation, if required, although we can advise on places to stay. There will also be a wine/cheese reception (sponsored by Promega) on the first day of the meeting. Abstract Submission All Workshop presentations will be in lecture format (15 or 30 minutes), chosen from abstracts submitted prior to the meeting. If you would like to present a paper at the Workshop please send your abstract by e-mail to the following address: MGD.Workshop@ich.ucl.ac.uk. With the authors' permission, abstracts will be published in Genetical Research.

The scheme is not intended to cover the costs of salaries for those engaged in the fieldwork or the training, nor to fund attendance at conferences. The work should include a strong genetical component. Eligibility: The scheme is open to any member of the Genetics Society who has been member for at least one year engaged in field based genetic research involving plants, animals, fungi or microbes. The research field should be one in which results would typically be suitable for publication in the Society’s journal Heredity. Only one application from any research group will be admissible in any one year. Applications should be made on the form available from the Genetics Society’s web page. The application form requests a short summary of the research project for which funds are sought. This should explain the role of the proposed field research in the overall project, and indicate how the grant will be used to facilitate the field research. A detailed budget for the fieldwork will be required, as well as an outline of other possible sources of funding. Applications from PhD students or post-docs should be accompanied by a letter or e-mail of support from your supervisor. ?? Closing date: There will be one closing date of 31st January each year. Awards will be announced within one month of the closing date to allow ample time for fieldwork preparation. At the end of the grant a short report will be requested from the grant holder.
