Dept. of Biological Sciences, University of Warwick, Gibbet=20
Hill Road, Coventry, CV4 7AL, UK
This EU-funded position is available starting April 2000 to investigate =
how genetic diversity among marine photosynthetic prokaryotes of the =
genera Synechococcus and Prochlorococcus is correlated with =
environmental adaptation. The project is part of an EU consortium =
project PICODIV (www.sb-roscoff.fr/Phyto/PICODIV/index.html) with =
participating laboratories in France (co-ordinator), Germany, Spain & =
Norway. You should have a PhD and experience in molecular biology. You =
will be highly motivated and have a particular interest in applying =
molecular and biochemical techniques to the biological oceanography of =
ecologically important microorganisms.=20
The post is for three years at a salary on the RA1A scale.

PICODIV : Genetic analysis of the spatial and temporal dynamics of =
photosynthetic picoplankton communities. Molecular biology techniques =
will be used to investigate how genetic diversity among marine =
photosynthetic prokaryotes is correlated with particular environmental =
adaptation. We have recently observed genotypic variation among natural =
populations of the marine cyanobacterium Prochlorococcus, which =
dominates the picophytoplankton in the world's oceans, associated with =
different depths in a stratified water column using 16S rRNA analysis =
and dot blot hybridisation technology (West & Scanlan 1999). Suitable =
oligonucleotide probes will be developed to extend this technology to =
the marine Synechococcus group. The spatial and temporal distribution of =
the major Prochlorococcus and Synechococcus genotypes will then be =
determined in natural water columns during a calendar year from the =
English Channel, Mediterranean Sea, North Sea and Gulf of Aqaba [Red =
Sea] Eilat, Israel, using various molecular ecological techniques =
including FISH. This will be compared with data obtained using =
denaturing gradient gel electrophoresis (DGGE), to investigate total =
picophytoplankton community genetic diversity. Genotypic variation will =
be correlated with physical and chemical properties of the water column =
and to the phenotypic response of Prochlorococcus and Synechococcus =
populations to environmental variables (see e.g. Scanlan et al., 1997).=20

Postdoctoral Position=20
Assessing and monitoring the diversity of eukaryotic photosynthetic =
picoplankton
Station Biologique de Roscoff
CNRS et Universit=E9 Pierre et Marie Curie
BP 74, 29682 Roscoff, France
This position will be funded by the FP5 EU program PICODIV to start in =
April 2000 which focuses on the diversity of eukaryotic photosynthetic =
picoplankton in coastal and oceanic waters.=20
Emphasis will be on the following aspects:
a.. Isolation and description of novel picoplankton strains from =
coastal and oceanic waters using a combination of techniques (electron =
microscopy, HPLC pigment signature, rDNA gene sequences).
b.. Direct determination of the environmental diversity from rDNA gene =
sequences
c.. Quantitative use of rDNA probes (quantitative PCR) to monitor =
picoplankton diversity at three european coastal sites
Skills :
a.. The candidate is expected to have a strong academic background, to =
have published in international peer-reviewed journals and to be able to =
conduct independent research
b.. Experience with modern taxonomical approaches inolving rDNA genes =
on bacteria or unicellular eukaryotes (cloning and sequencing of =
environmental samples, phylogenetical analysis, DGGE, rRNA probes, =
quantitative PCR) will be critical
c.. Experience in algal taxonomy and algal culture will be highly =
desirable
d.. Working knowledge of the French language will be an essential =
prerequisite for rapid integration in our team
Starting date: Spring 2000
Duration: 24 to 30 months
