Previous research at Chelechol ra Orrak in the Rock Islands of Palau has revealed several critical shifts in marine resource exploitation between ca. 3000/1700 – 0 BP. These changes include a decline in fishing, increased reliance on molluscs, particularly Mactra clams, and statistically significant size increases in one of the most heavily exploited gastropod species, Gibberulus (Strombus) gibberulus. Commonly invoked explanatory mechanisms, such as broad scale climate change and anthropogenic...
