Many (but not all) mollusc species that have a long history of subsistence harvesting have become smaller over time [14,16,20], suggestive of size-selective Contemporary, prehistoric and pre-human material was collected from the Bocas del Toro archipelago (figure 1). pugilis in Bocas del Toro decreases successively from pre-human to prehistoric to the contemporary Variation in size at maturity among contemporary populations also correlates with observed harvesting intensities.
