Can community structure track sea-level rise? Stress and competitive controls in tidal wetlands

Schile, Lisa M.; Callaway, John C.; Suding, Katharine N.; Kelly, N. M. (2017)

Climate change impacts, such as accelerated sea-level rise, will affect stress gradients, yet impacts on competition/stress tolerance trade-offs and shifts in distributions are unclear. Ecosystems with strong stress ...
Contributions of organic and inorganic matter to sediment volume and accretion in tidal wetlands at steady state

Morris, James T.; Barber, Donald C.; Callaway, John C.; Chambers, Randy; Hagen, Scott C.; Hopkinson, Charles S.; Johnson, Beverly J.; Megonigal, J. Patrick; Neubauer, Scott C.; Troxler, Tiffany; Wigand, Cathleen (2016)

A mixing model derived from first principles describes the bulk density (BD) of intertidal wetland sediments as a function of loss on ignition (LOI). The model assumes the bulk volume of sediment equates to the sum of ...
Modeling Tidal Marsh Distribution with Sea-Level Rise: Evaluating the Role of Vegetation, Sediment, and Upland Habitat in Marsh Resiliency

Schile, Lisa M.; Callaway, John C.; Morris, James T.; Stralberg, Diana; Parker, V. T.; Kelly, Maggi (2014)
