New paper in Evolution

Erol’s new paper with Jeremy Van Cleve is now in press at Evolution. We look at how the different mechanisms that can lead to social evolution interact with each other in unexpected ways. Link to the journal here; you can also access OA accepted version on arxiv and bioRxiv.


New paper out in the American Naturalist

In a new paper with Dustin Rubenstein and Sheng-Feng Shen in the American Naturalist, we look at how costly conflict should vary with group size in social animals. You can read the paper here: (Click on the publications tab above, if you don’t have subscription).

Postdoctoral fellow positions available

Postdoctoral fellowships are available to work with PI Erol Akcay on ecological and evolutionary theory, especially the theory of social evolution.

The Akcay lab ( is based in the Department of Biology at the University of Pennsylvania in Philadelphia, PA. We study a range of questions at the interface of ecology, evolution, and social dynamics, including: the evolution of social behaviors and social systems of animals and humans, evolutionary ecology of species interactions such as mutualisms, the interplay between physiology and social behavior, dynamics of coupled natural and human systems, and others. More information about the lab’s research and links to recent publications can be found at: The Biology Department and the University of Pennsylvania provide a vibrant intellectual environment for research in theoretical biology and social evolution, and ample opportunity for cross-disciplinary collaborations.

We are seeking enthusiastic and talented individuals to conduct original research on topics related to the lab’s interests. The specific area is flexible, and will be determined in agreement between the postdoctoral fellow and the PI. The ideal candidate will have a strong background in ecological, evolutionary, and/or economic theory (and a Ph.D. in a related field), and will have demonstrated ability to conduct original research. Start date is flexible but can be as early as January 2014. Funding is available for multiple years, contingent on satisfactory progress.

To apply, send a CV, statement of research interests (1 page), a representative paper or manuscript, and contact information for 3 references to Erol Akcay at Applications will be considered as they arrive; informal inquiries are welcome.
