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 2017. In each marsh zone at each GCE LTER permanent monitoring site, we counted the number of adult and juvenile snails in 8 replicate quadrats. 3. Study Type: Monitoring 4.

Objectives: The research proposed for GCE-III is designed to address how variations in salinity and inundation, driven by climate change and anthropogenic factors, affect biotic and ecosystem responses at different spatial and temporal scales, and to predict the consequences of these changes for habitat provisioning and carbon (C) sequestration across the coastal landscape. 5. Abstract: The Georgia Coastal Ecosystems (GCE) LTER is located along three adjacent sounds on the Atlantic coast and includes both intertidal marshes and estuaries. Long-term drivers of climate change, sea level rise and human alterations of the landscape will cause transitions in dominant habitat types (state changes) within the GCE domain by changing the amounts and patterns of water delivery across the landscape. These changes in water delivery can be conceptualized as presses and pulses in river inflow, local runoff, groundwater input, and tidal inundation, which will in turn manifest themselves as changes in salinity and inundation patterns in the domain. The research proposed for GCE-III is designed to address how variations in salinity and inundation, driven by climate change and anthropogenic factors, affect biotic and ecosystem responses at different spatial and temporal scales, and to predict the consequences of these changes for habitat provisioning and carbon (C) sequestration across the coastal landscape. The goals are to: 1) Track long-term changes in climate and human actions in the watershed and adjacent uplands, and evaluate the effects of these drivers on domain boundary conditions. 2) Describe temporal and spatial variability in physical, chemical, geological and biological, and to evaluate how they are affected by variations in river inflow and other boundary conditions. 3) Characterize the responses of three dominant habitats in the domain to pulses and presses in salinity and inundation. 4) Describe patterns of habitat provisioning and C sequestration and export in the GCE domain, and to evaluate how these might be affected by changes in salinity and inundation. These efforts will be synthesized into a synoptic understanding of both biotic and ecosystem responses to variations in salinity and inundation driven by climate change and human activities, which will be used to assess thresholds between habitats and the potential for state changes in the domain. 6.

History of Land Use and Disturbance: none recorded i. Climate: Climate summary for Sapelo Island, Georgia, based on NWS data from 1980-2010: Daily-aggregated Values: Mean (sample standard deviation) mean air temperature: 20.09°C (7.28°C) minimum air temperature: 15.02°C (7.96°C) maximum air temperature: 24.82°C (6.98°C) total precipitation: 3.26mm (10.3mm) Yearly-aggregated Daily Values: Mean (sample standard deviation) total precipitation (1980-2010): 1124mm (266mm) 2. Experimental or Sampling Design a. Design Characteristics: Survey of adult and juvenile periwinkle snail (Littoraria irrorata) in creekbank and mid-marsh zones across the GCE domain b. Permanent Plots: Adult snails were counted in 50cm x 50cm quadrats and juvenile snails in 25cm x 25cm quadrats c. Data Collection Duration and Frequency: Snail densities were collected in 8 replicate quadrats in each marsh zone (mid-marsh and creekbank) at each of the GCE LTER domain sites Beginning of Observations: Oct 13, 2017 End of Observations: Oct 28, 2017 3. Research Methods a. Field and Laboratory Methods: Method 1 -- Method 1 -- Method 1 -- Survey -- At each site, 8 (creekbank) and 8 (mid-marsh) quadrats were haphazardly positioned in line with the permanent vegetation plots. In each 50cm x 50cm plot, all “visible” Littoraria were counted, ignoring the tiny individuals that are not obvious to a simple visual scan. Then a 25 x 0.25 cm quadrat was placed in the center of the plot, and every plant stem was sampled for “recruit” individuals, looking inside all leaf furls. To do this, the furled leaf was pulled from the stem and any juvenile snails that were between 1-4mm at the base of the leaf were counted. b. Protocols: none c.
