PhD position in soil microbial ecology: Sweden/France
Swedish University of Agricultural Sciences (SLU), Uppsala, Sweden and SATT SAYENS (SAYENS), Dijon, France are offering a PhD position in soil microbial ecology, expected to start May 2021 or as soon as possible thereafter. The PhD will be awarded by the Swedish University of Agricultural Sciences. This position is part of the MSCA-ITN-H2020 project ARISTO – European Industry – Academia Network for Revising and Advancing the Assessment of the Soil Microbial Toxicity of Pesticides.
Project title: Assessment of the ecotoxicity of pesticides on nitrifiers in soil
Project description of the PhD student: To detect potential toxic effects of pesticides on natural microbial soil assemblages, bacteria and archaea involved in nitrification will be used as indicators. Toxic effects can be both direct and indirect, affecting the functioning of soils and their capacity to cope with additional stressors. The aim of the PhD student project is to assess the toxicity of pesticides on the function and diversity of ammonia oxidizing bacteria and archaea, and on other functional groups involved in nitrification in soil. Specific objectives are to identify (i) toxicity endpoints on activity, abundance and diversity of nitrifiers; (ii) toxicity mechanisms on ammonia oxidizing bacteria and archaea; (iii) interaction effects on functional groups involved in nitrification; (iv) stability of functional groups involved in nitrification (i.e. resistance and resilience to secondary stressors). This work goes beyond direct effects of pesticides on ammonia oxidizing bacteria and archaea and brings new knowledge on the use of stability of soil functioning as a bioindicator and establishes novel procedures for assessing pesticide toxicity on soil microorganisms. The PhD student will work with lab and field experiments using a range of molecular techniques (e.g. amplicon sequencing, qPCR) as well as bioinformatic and biostatistical tools. This PhD project involves also secondments for short periods as given below.
Principal supervisor: Prof. Sara Hallin, email@example.com, and Dr. Abdelwahad Echairi, firstname.lastname@example.org
Planned secondments: Ecole Centrale de Lyon, France. Supervisor: Prof. G. Nicol (2 months). Purpose: analyses based on Stable Isotope Proping (SIP) to obtain insights on toxicity mechanisms of pesticides on ammonia-oxidizing microorganisms.
