McComas 2017 Vector Digital Data Set (Point) and tabular data (csv) Lafayette, LA U.S. Geological Survey https://doi.org/10.5066/F7G44NFJ Above- and belowground production in coastal wetlands are important contributors to carbon accumulation and ecosystem sustainability. As sea level rises, we can expect shifts to more salt-tolerant communities, which may alter these ecosystem functions and services. Although the direct influence of salinity on species-level primary production has been documented, we lack an understanding of the landscape-level response of coastal wetlands to increasing salinity. What are the indirect effects of sea-level rise, i.e. how does primary production vary across a landscape gradient of increasing salinity that incorporates changes in wetland type? We measured above- and belowground production in four wetland types that span an entire coastal gradient from fresh to saline marsh. These data were used to identify patterns in primary production at the landscape scale and implications of sea-level rise on wetland sustainability and ecosystem services.

We adopted the following statement regarding data archiving and sharing from Wright et al. (2004): "The authors believe that the archiving and sharing of large datasets is important for advancing ecology as a discipline. At the same time, for data sharing to be successful and sustainable, it is imperative that all those involved in data acquisition, archiving and use do so in an ethical manner. In particular, we believe that those individuals whose time, efforts and intellect designed and created the studies are acknowledged appropriately." Text in quotation from: Wright, I. J., P. B. Reich, M. Westoby, D. D. Ackerly, Z. Baruch, F. Bongers, J. Cavender-Bares, T. Chapin, J. H. Cornelissen, and M. Diemer. 2004. The worldwide leaf economics spectrum. Nature 428:821-827.
