Welcome to the personal scientific website of Prof. Theo C. M. Bakker, University of Bonn, Germany. It gives an overview of my research and publications, emphasizing my work on sticklebacks during the past 35 years.

We (Rebeca Rosengaus, James Traniello and Theo Bakker) just published the introduction to the Topical Collection “Sociality and Disease“ in Behavioral Ecology and Sociobiology. The coronavirus pandemic provide a timely illustration of the importance of basic and applied socioecoimmunological research from a broad phylogenetic perspective. The TC, which contains 15 papers, provides a timely focus on the bidirectional dynamics between social hosts and their pathogens in a diverse array of invertebrate and vertebrate clades. 

Starting with the April issue, BES has a new cover image.

Honey bees (Apis mellifera) minimize the spread of disease by altruistic self-exile and the physical eviction of immune-challenged workers.

the second paper in Current Zoology came out and looked at UVA-based shoaling and mate preferences of lab-bred fishes from two photic habitats. The results for both shoaling- and mate preference tests were largely similar for wild-caught and lab-bred sticklebacks, thus hinting at a genetic basis for the preference patterns.
