The NIOO-KNAW offers a position for a *Bioinformatician / Quantitative Ecologist – post-doc* *Project description* The key question this project addresses is to what extend open access data, now often required by journals to be deposited in data repositories such as Dryad, can be used in meta-analysis. What are the pitfalls and what are the advantages over traditional meta-analysis? To explore this question the post-doc will closely collaborate with a number of researchers from all four departments at the NIOO. These researchers will carry out meta-analyses to answer a range of ecological questions (such as “How do richness patterns relate to environmental C:N:P stoichiometry across kingdoms and ecosystems?”, “Is rarity (type) phylogenetically conserved among microbes?” and “Does additive genetic variation in traits, and thereby the potential for evolutionary responses, vary with environmental conditions?”). The post-doc will support these analyses and use the experiences as input to address the key-question of this project, which should result in a methodological paper. The post-doc will thus play a central role in a small group of enthusiastic ecologists to explore a potentially new ‘niche’ in ecological research methods. *Requirements* We are looking for a highly motivated and enthusiastic person with a PhD in bioinformatics or ecology and experienced in working with large datasets (‘big data’) and preferably with meta-analysis. Affinity with ecological research is a pre-requisite, as well as the ability to work in a team. More info: https://nioo.knaw.nl/nl/vacatures/bioinformatician-quantitative-ecologist-%E...
