The Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin is Germany’s premier wildlife research institute and funded
by the federal government of Germany and the state government of Berlin. The IZW focuses on the life histories and mechanisms of
evolutionary adaptations of mammals and birds and their conservation in natural and anthropogenically influenced environments. The institute
operates within the fields of evolutionary ecology and genetics, wildlife diseases and reproduction biology and management, has excellent
facilities and is currently expanding its research programme (http://www.izw-berlin.de).
The institute has received funding for a major network project on “olfactory mate choice - immune system, olfactory receptors
and their adaptive value” under the leadership of Prof Dr Simone Sommer. Olfaction plays a central role for mate choice in mammals, but there
is a lack of understanding of the underlying proximate and ultimate aspects of olfactory signal evolution. Recent studies highlighted the
importance of the major histocompatibility complex (MHC) for female choice which raises the question how volatiles, olfactory receptors and the MHC
co-evolved in mammalian mating systems. The overall project will use a broad genomic and immunological approach to analyse this question, thereby combining
state-of-the-art transcriptome analyses with detailed immunological studies and extensive field work in long-term projects on two species with
contrasting social and mating systems, the greater sac-winged bat in Costa Rica and the spotted hyena in Tanzania. The network consists of the IZW
(olfactory mate choice, Prof Dr Simone Sommer, PD Dr Christian Voigt, Dr Marion East, Prof Dr Heribert Hofer), the Leibniz Institute for Age
Research in Jena (transcriptome analysis, PD Dr Matthias Platzer), the Charité in Berlin (immunogenetics, Prof Dr Andreas Ziegler, Dr. Barbara Uchanska-Ziegler) and the University of Geneva,
Switzerland (olfactory receptor genes, Prof Dr Michel Milinkovitch). Currently we seek applications for:

1 Postdoc: evolutionary immune genetics of mate choice (ref: 13/2009) The postdoc will co-ordinate the network, study the MHC of both study
species and co-ordinate lab and field work in Berlin. The successful candidate will have a PhD in evolutionary genetics, zoology or related
disciplines, a strong background in behavioural ecology, genetics and evolution, excellent knowledge of statistics, organisational skills, and
a strong publication record. Experience in evolutionary immune genetics, particularly MHC, olfaction, and mammalian mating systems will be an
advantage.

1 Phd: mate choice and olfaction in bats (ref: 14/2009) This project will focus on mate choice mechanisms in the harem-polygynous social system of the greater sac-winged bat (Saccopteryx
bilineata) by combining behavioural, immunological and genetic work. In colonies of Saccopteryx bilineata territorial males each defend a group of females,
despite their incapability to monopolise the reproductive success with harem females. During courtship, males display scent compounds from pouches in their wing membranes in front of females
and females probably base their mate choice decision mostly on volatiles. Field work will include odour collection, tissue collection and
behavioural observations including choice experiments. Laboratory work includes chemical, immunological and/or genetic work. The successful candidate
will have a diploma or MSc in Biology, Zoology or related disciplines, a strong background in behavioural ecology, genetics and evolution, above average achievements in undergraduate studies,
excellent knowledge of statistics, organisational skills, ability to work under difficult conditions in a team and profound knowledge of English (speaking and
writing). Experience in field work, immunological or molecular genetic lab work and knowledge of Spanish will be an advantage.

1 Phd: mate choice and olfaction in spotted hyenas (ref: 15/2009) This project will integrate genetic, chemical and behavioural aspects of olfaction to investigate the importance of olfactory
cues in mate choice in the spotted hyena (Crocuta crocuta); a social carnivore that exhibits strong female mate choice. The candidate will conduct field work for approximately six months per year on a well
studied population of individually known spotted hyenas in the Serengeti, Tanzania. Field work will entail both the collection of detailed behaviour data and odour
and genetic samples from known individuals. Laboratory work will involve olfactory analyses, immunological and/or genetic work. The successful candidate will have a diploma or MSc in Biology, Zoology or
related disciplines, require experience of behavioural research, above average achievements in undergraduate studies, excellent knowledge of statistics, organisational skills, a proven ability in the lab, a
driving licence, good spoken and written English, and an ability to work independently in challenging field situations in Africa.

All positions are limited to three years - starting dates are at the earliest on 1st September 2009. The IZW is determined to increase the
proportion of women in successful scientific careers and particularly encourages female scientists to apply. For further information please contact Prof Dr Simone Sommer (immune genetics,
+49-30-5168-315, sommer@izw-berlin.de), PD Dr Christian Voigt (bats, +49-30-5168-517, voigt@izw-berlin.de), Dr Marion East or Prof Dr Heribert Hofer (hyenas,
+49-30-5168-512, east@ izw-berlin.de). Candidates should submit an electronic application with a letter clearly indicating which position they apply for, explain their interests in it and
particular skills for it, enclose a CV, a summary of their PhD thesis (postdoc position), Diploma or Master Thesis (PhD positions), copies of relevant degrees,
two letters of recommendation and publication list (if available) preferentially before 15 July 2009 (PhD positions) and 15 August 2009
(Postdoc position). We will consider applications until the position is filled and expect to hold an initial round of PhD candidate interviews on Friday 24 July 2009. Applications should be sent to the
