    Ph.D. position available „Ontogeny of sexual size dimorphism in lizards”, Charles University, Prague, Czech Republic

    Body size is a crucial trait connected to nearly every aspect of animal life. It is very often
    sexually dimorphic. Despite its central importance, proximate mechanisms of intra- and

    interspecific variability in body size are still not well understood.

    The aim of the Ph.D. project is to compare the ontogeny of structural size, steroid levels,
    bone growth plates and mainly gene expression of genes associated with growth
    hormone/insulin-like growth axis and of receptors for androgen and estrogen between
    female-larger and male-larger gecko species.

    The current project is based on our long-term research of the control of body size and sexual size dimorphism in
    reptiles. For more details please see e.g.:

    corresponds to intraspecific temperature-induced variation. J Evol Biol 23, 670-677.

    The successful applicant must hold a Master of Science (M.Sc.) in Biology/Ecology or related fields, has
    experience with experimental work with animals or experience in the DNA/RNA lab, enthusiasm, reliability
    and good knowledge of written and spoken English.
