Fiddler crab density in Plum Island Sound estuary, Rowley, Massachusetts

Abstract: 

Climate change is predicted to shift or extend the range of warm-water species poleward. In 2014, the fiddler crab, Minuca (Uca) pugnax, was  observed for the first time in PIE, which is north of its historical range.  Beginning in 2014, density estimates were collected.

Methods: 

Data are collected from  10-20 randomly selected points along a 200 m transect. 0 mark is frequently the confluence of tidal creeks, except WE-L. At each point, a 0.0625m2 (except 2016 when it was 0.16 m2) quadrat was placed  within the creek bank Spartina alterniflora and on the vertical surface of the creek wall. Within each quadrat, the number of burrows are quantified, in addition to any other macro-invertebrates (snails, mussels, etc). 

Measurements are made in the marshes around the tidals creeks, Nelson, Clubhead, Sweeney, and West.
