Predation as a mechanism of invasion resistance Consumption of non-native Crassostrea ariakensis oysters by the blue crab, Callinectes sapidus Melanie J. Bishop, Charles H. Peterson University of North Carolina at Chapel Hill

Crassostrea ariakensis Rapid growth Early maturity Broad native range

+ = ? Crassostrea ariakensis Blue crabs Rapid growth Early maturity Broad native range “Keystone” predator

Laboratory experiments In sandy-bottomed aquaria, using triploid oysters minimizes risk enables observation of foraging Single adult crabs (> 80 mm SH) Satiated and starved Equal numbers of C. ariakensis and C. virginica (25 of each) Oysters enumerated every 12 hr Crabs allowed to feed until ~25% oysters consumed C. virginica C. ariakensis

Consumption of small (~25 mm) and large (~35 mm) C Consumption of small (~25 mm) and large (~35 mm) C. ariakensis (A) and C. virginica (V) 2

Consumption of large ([L], 40 mm) and small ([S], 30 mm) oysters 2

Is consumption of C. ariakensis affected by experience?

Are blue crabs choosing C. ariakensis?

Force required to crush oysters

Transplant experiment 2. C. virginica tissue into C. virginica shell 1. C. ariakensis tissue into C. ariakensis shell 4. C. ariakensis tissue into C. virginica shell 3. C. virginica tissue into C. ariakensis shell If shell strength is sole factor that determines relative rate of consumption of the two species: rate of consumption 1 = 3; 2 = 4

Results: Transplant experiment

Summary of results Consumption: A > V across large range of sizes Mechanism: biomechanics of shell strength Penalty for rapid growth of C. ariakensis is thin shell Results conflict with the prevailing dogma that rapid development is a good predictor of invasion potential

So what?

Applying results of laboratory experiments to the real world Use predation on C. virginica as standard Shells of 50-60 mm C. ariakensis are as resistant to crushing as 15-25 mm C. virginica C. ariakensis appears less gregarious than reef-forming C. virginica Compare environmental tolerances of predator and prey Blue crabs and C. ariakensis tolerate similar environmental conditions Consideration of evolutionary history of C. ariakensis
