- •
Marine resource shifts at Chelechol ra Orrak, Palau, imply declining foraging efficiency.
- •
Possible resource depression is tested using median size of parrotfish genera.
- •
Scarus size is unchanged; Chlorurus size increases over 1500 years.
- •
Overfishing is rejected as a cause of resource shifts.
- •
The significance of prey size change in human paleoecology is critically evaluated.
