Sourced from the stated research gap and inline gaps and future-work section of the source papers, classified as general, drawn from work published between 1986 and 2026, spanning 3 journals. Those papers have been cited 60 times in total.

Supporting evidence — 4 representative gaps

• Geomorphic Comparison of Three Globally Significant Wetland Landscapes (2025) · Environments · doi

  The geomorphic factors influencing water flow and material exchange in marshes are poorly understood. There is a lack of understanding of how drainage density and drainage efficiency relate to each other. The study aims to address this gap by comparing the morphology of three distinct marsh landscapes.

• Spatial Analysis of Shoreline Erosion, Delaware Bay, New Jersey (1986) · Annals of the Association of American Geographers · cited 60× · doi

  While the occur- rence and evolution of coastal wetlands is rela- tively well understood, the processes causing spatial variation within the marsh landscape are not well understood. These results point to a need for further study of geomorphological, ecological, and pedologi- cal processes in tidal marshes.

  Further studies are needed to investigate the long-term effects of crab herbivory on salt marsh ecosystems, - Research should focus on the interactions between crabs, vegetation, and sediment dynamics in different environmental contexts, - The role of other biotic and abiotic factors in shaping salt marsh geomorphic evolution should be explored

  The impact of crab activity on salt marsh geomorphic evolution is poorly understood. There is a lack of research on the role of crab herbivory in suppressing vegetation establishment. The relationships between vegetation, sediment deposition, and sea-level rise are not well understood.
