Peter Dijkstra

Peter Dijkstra is an Associate Professor in the Department of Biology at Central Michigan University, where he leads the Dijkstra Lab. His research integrates behavioral ecology, animal physiology, and neurogenomics to study social behavior and evolutionary processes in African cichlid fish. He teaches courses in Animal Physiology, Behavioral Ecology, Developmental Biology, and Introductory Biology.

Research Interests:

• Behavioral Ecology
• Animal Physiology
• Endocrinology
• Evolution
• Neuroethology
• Oxidative Stress and Social Behavior
• Sexual Selection and Color Signaling

His recent research has focused on the physiological costs of social dominance, reproduction, and maternal care, especially in relation to oxidative stress and antioxidant responses. His lab investigates how developmental stress influences fitness-related traits such as pigmentation and aggression.

The 15 most recent publications show a consistent focus on social behavior in cichlids, particularly examining oxidative stress, dominance hierarchies, maternal investment, and color signaling. Keywords across these works include Behavioral Ecology, Animal Physiology, Oxidative Stress, and Evolution, with subfields ranging from filial cannibalism to social network dynamics and hormonal regulation. These studies employ integrative approaches combining behavior, physiology, and genomics.

Education:

• Ph.D., University of Groningen, the Netherlands, 2006
• Postdoctoral Researcher, University of Glasgow, Scotland, 2007–2009
• Postdoctoral Researcher, University of Texas at Austin, 2009–2012

Scientific Contributions:

• Published in high-impact journals such as Proceedings of the Royal Society B, Behavioral Ecology, and Integrative and Comparative Biology
• Research covered in media outlets, including topics like 'Why do mothers eat their babies?'
• Active collaboration with researchers across institutions

Advising and Grants:
While no formal list of students is provided, Dr. Dijkstra has co-authored multiple papers with early-career researchers, suggesting active mentorship. His lab is supported by institutional and likely external funding, enabling long-term research on cichlid behavior and stress physiology. Future work appears directed at understanding brain function and stress resilience in social contexts.

Lab and Research Team:
The Dijkstra Lab at Central Michigan University maintains a community of cichlid fish for studying social behavior. The lab combines behavioral observation, physiological assays, and neurogenomic analysis. Research spotlight areas include social stress and the brain, sexual selection, and maternal behavior, with findings contributing to broader theories in evolutionary biology and stress physiology.
