The effects of
burrow or burrow mimic
opening size on the four
parameters reflecting crab
excavation and burrow
mimic deposition in
Phragmites and Spartina
marshes and mudflats
over a 5-d sampling
period. (A) Excavating
rate by crabs (g d-1); (B)
deposition rate per
burrow mimics (g d-1);
(C) deposition efficiency
(g d-1 cm-3); (D) net
transport to the marsh
surface (g d-1). The data
are separately presented
for small (diameter: 0–
15 mm), medium
(diameter: 15–30 mm)
and large (diameter:
>30 mm) crab burrows..
