英文摘要 | Tidal wetlands are among the most valuable ecosystems in the world in terms of ecosystem service value, and the strategic management of their carbon resources is an important part of climate change mitigation. Tidal wetland soils contain relatively high quantities of soil organic carbon (SOC); yet there is little information about whether this SOC can be predicted based on easily identifiable environmental factors. We investigated how tidal wetland SOC density was distributed across the continental United States among various coastal locations, estuarine typologies, vegetation types, water regimes, and management regimes and found that knowledge of a wetland's coastal affiliation provided the most differentiation (whether on the East Coast, West Coast, or Gulf Coast). We then sought to identify whether SOC density was correlated with 47 different environmental variables and found that knowledge based on latitude and precipitation explained ~46% of the variance in SOC density for wetlands on the West Coast and Gulf Coast, respectively. Several other geographic, oceanic, terrestrial, and atmospheric factors were cross-correlated along these axes, including oceanic salinity, temperature, and average catchment elevation. For the U.S. East Coast, SOC density was not simple to explain and was likely dependent on a wide range of interacting and complex factors. This synthetic work can provide a better understanding of how changing environmental and social conditions can lead to enhanced or degraded carbon sequestration rates in times of rapid global change. ©2019.
