Assignment # 3: Summarize the Reznick et al. 1990 article in 100 words or less. Reznick DA, Bryga H, Endler JA. 1990. Experimentally induced life-history evolution in a natural population. Nature 346: 357-359. SUMMARY. Reznick et al. show that size-selective predation by predators dinfluences the evolution of life history characters in guppies (Poecilia reticulata).
Observation revealed that guppies in cichlid (Crenicichla alta) pools mature sooner and at a smaller body size than did guppies in killifish (Rivulus hartii) pools; cichlids eat larger guppies and killifish eat smaller guppies. Guppies were transplanted from cichlid pools to killifish pools, and the transplant (experimental) and control populations were tracked for 11 years. The authors found that guppies
