Dataset: A. pisonii: predation
Deployment: Griffen_mangroves

We investigated size-specific predation potential in both mangrove and mixed marsh habitats. Because large individuals (carapace width >15 mm) are not present in mixed marshes, small individuals (8-15 mm CW) were collected from the mixed marsh (Anastasia State Park, FL) and large (18-25 mm CW) from the mangroves (Avalon State Park, FL) for tethering at both habitats. We brought A. pisonii into the laboratory and affixed monofilament tethers (45 cm of 10 lb test) by tying a loop in the monofilament and attaching this loop to the back of the carapace using cyanoacrylate glue. Crabs were maintained in individual aquaria overnight and observed the following morning to ensure that tethers remained secure. Crabs were then transported to the field at low tide. Tethers were attached to mangrove roots or dead Spartina stalks above the low tide line such that individuals could access the water to stay moist at low tide and exit the water at high tide. Individuals were left in the field for 24 hours and then checked for survival as well as any indications of predation (e.g pieces of carapace remaining on tether) during low tide. Individuals that were no longer on the tether were classified as "consumed", while those still on the tether and alive were classified as "alive". This tethering protocol was repeated four times in each habitat.
