The greenhouse gas flux and potential global warming feedbacks of a northern macrotidal and microtidal salt marsh The greenhouse gas flux and potential global warming feedbacks of a northern macrotidal and microtidal salt marsh
Conversion of wetlands by drainage for agriculture or other anthropogenic activities could have a negative or positive feedback to global warming (GWF). We suggest that a major predictor of the GWF is salinity of the wetland soil (a proxy for available sulfate), a factor often ignored in other studies. We assess the radiative balance of two northern salt marshes with average soil...

Influence of tidal range on the stability of coastal marshland Influence of tidal range on the stability of coastal marshland
Early comparisons between rates of vertical accretion and sea level rise across marshes in different tidal ranges inspired a paradigm that marshes in high tidal range environments are more resilient to sea level rise than marshes in low tidal range environments. We use field‐based observations to propose a relationship between vegetation growth and tidal range and to adapt two numerical...

Prairie wetland complexes as landscape functional units in a changing climate Prairie wetland complexes as landscape functional units in a changing climate
The wetland complex is the functional ecological unit of the prairie pothole region (PPR) of central North America. Diverse complexes of wetlands contribute high spatial and temporal environmental heterogeneity, productivity, and biodiversity to these glaciated prairie landscapes. Climatewarming simulations using the new model WETLANDSCAPE (WLS) project major reductions in water volume...

Limits on the adaptability of coastal marshes to rising sea level Limits on the adaptability of coastal marshes to rising sea level
Assumptions of a static landscape inspire predictions that about half of the world's coastal wetlands will submerge during this century in response to sea-level acceleration. In contrast, we use simulations from five numerical models to quantify the conditions under which ecogeomorphic feedbacks allow coastal wetlands to adapt to projected changes in sea level. In contrast to previous...
