Department of Ecology and Evolutionary Biology, Yale University, New Haven, Connecticut 06520 8106, USA
Evolution 61:2516-27. 2007..We discuss the relevance of our findings for selection occurring in natural phage populations and for the general evolutionary epidemiology of infectious parasites...
- Viral ecology and the maintenance of novel host useJohn J Dennehy
Department of Ecology and Evolutionary Biology, Yale University, New Haven, Connecticut 06520, USA
Am Nat 167:429-39. 2006..We argue that this effect should facilitate adaptation by the virus to utilize the novel host--often crucial in subsequent phases of emergence...

- Reduced fecundity is the cost of cheating in RNA virus phi6John J Dennehy
Department of Ecology and Evolutionary Biology, Yale University, PO Box 208106, New Haven, CT 06520, USA
Proc Biol Sci 271:2275-82. 2004..Our data suggest that interference competition allows high fitness of derived cheaters in mixed infections, and we discuss preferential encapsidation as one possible mechanism...
