Title:

Survey of adult and juvenile periwinkle snail (Littoraria irrorata) density in mid-marsh and creekbank plots at GCE LTER study sites in October 2022.

Abstract:

To characterize spatial variation in the adult and juvenile density of periwinkle snails, Littoraria irrorata, within two zones in the salt marsh, the mid-marsh and creekbank, and across a gradient in salinity and distance to ocean, we surveyed snail density in October 2022. In each marsh zone at each GCE LTER permanent monitoring site, we counted the number of adult and juvenile snails in 8 creekbank and 12 mid-marsh replicate quadrats.
