A generalist microbial predator shows innate attraction to more profitable prey, but does not learn from experience

P. M. Shreenidhi, Rachel I. McCabe, H Liang, Margaret I. Steele, David C. Queller, Joan E. Strassmann

This study shows that Dictyostelium discoideum amoebas are innately attracted to more profitable prey bacteria and do not learn from experience to change their preference.

Predation limits the abundance of {triangleup}gacA cheaters in Pseudomonas protegens populations

Margaret I. Steele, Emily E Oxender, Carol Ge, David C. Queller, Joan E. Strassmann

The paper shows that {Delta}gacA mutants in Pseudomonas protegens are cheaters whose fitness depends on their abundance, and protozoan predators limit their spread.

The genetic basis of predation resistance in Pseudomonas species associated with the bactivorous soil amoeba Dictyostelium discoideum.

Margaret I. Steele, Jessica M. Peiser, Simon P. M. Dawson, David C. Queller, Joan E. Strassmann

The paper identifies genes required for predation resistance in three Pseudomonas species associated with Dictyostelium discoideum, revealing conserved and species-specific mechanisms.
