1) What are the types of human pressures acting on beach-dune
systems that have been assessed with ghost crabs?
2.) What is the magnitude of reported ecological effect sizes for
different stressors?
3.) Which metrics (response variables) have been used?
4.) What are the gaps in terms of human pressures currently not
adequately assessed using ghost crabs?
5.) What opportunities exist to advance the use of ghost crabs as
ecological indicators on ocean beaches?
