©2026 Biological and Chemical Oceanography Data Management Office.The impact of invasive predators during the early stages of invasion is often variable in space and time. Such variation is expected to initially favor plasticity in prey defenses but fixed defenses as invaders become established. Coincident with the range expansion of an invasive predatory crab in the Gulf of Maine we document rapid changes in shell thickness – a key defense against shell crushing predators – of an intertidal snail. Field experiments, conducted 20 years apart, revealed that tem...
