Tidal Attenuation and Poor Drainage Make Interior Microtidal Marshes Vulnerable to Sea Level Rise Open
Empirical and simulation models often assume a uniform tidal range across marsh platforms to predict marsh vulnerability to sea level rise (SLR), overlooking the hydrological heterogeneity caused by tidal attenuation and drainage condition…

Beyond the mangroves: a global synthesis of tidal forested wetland types, drivers and future information needs Open
There is increasing awareness of the global diversity of tidal forested wetlands (TFWs) and their significance in the provision of ecosystem services. These ecosystems, including mangrove forests, tidal freshwater forested wetlands, suprat…

Drivers of Elevation Change in a Retreating Coastal Forest Open
The future of coastal marshes depends in part on their ability to migrate inland with sea level rise into coastal forests, but projections of land conversion commonly assume that migration occurs over a static terrestrial topography. Here,…

Recruitment bottlenecks and reinforcing environmental degradation drive marsh collapse Open
Ecosystem collapse is often attributed to the absence of stress-tolerant species, yet many climate-stressed systems fail even when these species remain regionally present. This raises a critical, unresolved question: does collapse result f…

Plant competition dominates grass species interactions in a migrating marsh-forest ecotone Open
Ecotone communities are areas of high species turnover and steep environmental gradients. We investigated how environmental gradients shape species interactions between upland and tidal wetland grass species to shed light on zonation in th…

Shifts in light availability driven by dieback across a marsh‐forest gradient Open
Ecological zonation in coastal forests is driven by sea level rise and storm‐surge events. Mature trees that can survive moderately saline conditions show signs of stress when soil salinity increases above its tolerance levels. As leaf bur…

Early detection of invasive Phragmites australis at the tidal marsh-forest ecotone with airborne LiDAR Open
Wetlands across North America are invaded by an introduced lineage of the common reed Phragmites australis, and sea level rise has exacerbated the spread of this species. P. australis at tidal marsh-forest ecotones has rapidly been expandi…

Feedbacks Regulating the Salinization of Coastal Landscapes Open
The impact of saltwater intrusion on coastal forests and farmland is typically understood as sea-level-driven inundation of a static terrestrial landscape, where ecosystems neither adapt to nor influence saltwater intrusion. Yet recent obs…

Plasticity drives the trait variation of a foundation marsh species migrating into coastal forests with sea‐level rise Open
Climate‐driven ecosystem shifts occur through turnover in the foundation species which structure the landscape. Therefore, to predict the fate of areas undergoing climate‐driven ecosystem shifts, one approach is to characterize ecological …

Litter Decomposition in Retreating Coastal Forests Open
Rising sea levels lead to the migration of salt marshes into coastal forests, thereby shifting both ecosystem composition and function. In this study, we investigate leaf litter decomposition, a critical component of forest carbon cycling,…

Hydrological, biogeochemical, and ecological linkages at the land-sea margin: Insights from a coastal critical zone network Open
Ghost forests and abandoned farms are stark indicators of ecological change along world coastlines, caused by sea level rise (SLR). These changes adversely affect terrestrial ecosystems and economies, but expanding coastal marshes resultin…

Storm Surges and Sea Level Rise Cluster Hydrological Variables Across a Coastal Forest Bordering a Salt Marsh Open
Sea level rise and storm surges drive coastal forest retreat and salt marsh expansion. Both salinization and flooding control ecological zonation and ecosystem transition in coastal areas. Hydrological variables, if coupled with ecological…

Tidal attenuation and poor drainage drive vulnerability of interior microtidal marshes to sea level rise Open
Tidal marsh stability under Sea Level Rise (SLR) is driven by feedbacks between marsh macrophyte productivity, sediment accretion, and surface elevation gain. Predictive models and empirical studies often assume a spatially uniform tidal r…

Distinguishing the Effects of Stress Intensity and Stress Duration in Plant Responses to Salinity Open
Species-specific variation in response to stress is a key driver of ecological patterns. As climate change alters stress regimes, coastal plants are experiencing intensifying salinity stress due to sea-level rise and more intense storms. T…

Shrub expansion in maritime forest responding to sea level rise Open
Expansion of shrubs has been observed in a number of biomes and in response to diverse global change drivers. Noting shrub expansion in coastal forests affected by sea level rise, we began to monitor shrub populations in a transgressing lo…
