Project: A biosystematic revision of the family Cribrariaceae
Function: Doctoral candidate, assistant at 70%
Registration deadline: 11th February 2022
Contract starting date: 1st September 2022 (3 years)
Key words: phylogeny; species delimitation; systematics & integrative taxonomy.

Job description:
The present project is focused on one of the most neglected groups of Myxomycetes (Amoebozoa), the family Cribrariaceae. The generic and species boundaries, as well as the evolution of phenotypic traits, have never been analyzed in detail, and especially not in a phylogenetic context and with modern techniques. The monophyly of the group and currently accepted genera needs first to be tested using a fair taxonomic sampling, under a multilocus aproach. We will next explore the evolution of some phenotypic traits (notably, the sporophore macromorphology and the spore ornamentation, but also other characters) and the ecology of the species, to assess its relevance for the taxonomy and diversification of the group. Finally, we will address the species-level taxonomy, identify new species and cryptic taxa, and evaluate synonymies. With all this information, we expect to propose a revised classification and an updated monograph of the family. Most of the skills and data analyses learned upon completion of the project will be applicable not only to the study of Myxomycetes, but also to the systematics and taxonomy of other biological groups.

Required degrees and skills:
• Master in Biology or in a Biosystematics-related topic in Environmental/Chemistry/Health Sciences.
• Skills in Fungal/Botanical Systematics and Taxonomy, especially microscopy.
• Skills in molecular lab and phylogenetic analyses.
• Interest for the morphological, evolutionary and taxonomic study of Myxomycetes.
• Motivation to engage in the research project, including: (i) field work (Europe, perhaps South America) and in vitro cultures, (ii) data gathering and analyses, (iii) writting of a doctoral thesis, (iv) presentation and dissemination of the project results (scientific journal publication and others).
• Good disposition to work in a team and to participate in the scientific life of the host institute.
• Proficiency in written and spoken French (mother tongue or a minimum of level C in CEFR scale) in order to ensure an adequate flow of the practical work of the Systematics and Biodiversity course, given in Biology to 2nd year students, which she/he would be responsible for.
• The working language of the project being English, the candidate must also be particularly comfortable in this language (written and spoken).

Within the research project, the candidate will profit from aid, guidance and supervision in the different steps of the project, from specimen handling, data gathering and analyses, to presentation of the results and scientific writing. In addition, the candidate is expected to build up a network of national and international collaborations, perform short stays abroad, and become used to the dynamic of scientific research to become an independent researcher.

The assistant position is under the direction of Dr. Juan Carlos Zamora (CJBG) and Dr. Carlos Lado (RJB-CSIC).
