How to find us M. (Marion) Nicolaus, PhD

Research interests

I am an enthusiastic behavioural and evolutionary ecologist, broadly interested in the evolution of individual variation in behaviours and life-history strategies in wild animal populations. I am particularly interested in the role of social effects in the emergence and maintenance of observed phenotypic variation.

I’m currently employed as a postdoc researcher and work on a range of topics: evolution of animal personality, local adaptation processes, dispersal ecology, life-history evolution and avian colouration.

I conduct most of my research on long-term monitored passerine populations performing large-scale experiments in the wild and using tools from behavioural ecology and quantitative genetics.

You can also find me on Researche Gate ; Google Scholar and my personal blog
