| contents | <p>Tidal mudflats are distributed globally, providing flood protection, water quality, and food production for millions of people. They host very productive mats of sediment dwelling micro-algae, or microphytobenthos (MPB), inhabiting the top few micrometers of the sediment. MPB mats can produce daily as much organic carbon as phytoplankton do in coastal waters. They foster numerous ecosystem services within the land-to-ocean interface8,9, including CO2 removal potential10. They provide the most important energy source for consumers of the benthic microfauna, meiofauna, macrofauna to birds and fishes, and thus support to the whole food web. The high MPB production on mudflats contributes to the development of shellfish farming, in particular oyster and mussel that largely feed on MPB12,13. As tidal MPB only develop during low tides in emerged sediments directly exposed to atmosphere, net primary production (NPP) is driven by sharp and rapid changes in downwelling irradiance and mud surface temperature (MST)14. MPB can take advantage of high light and temperature conditions until a certain threshold beyond which photo- and thermoinhibition can occur. Such a high sensitivity to the radiative forcing raises concerns on how MPB standing stock and production will respond to climate change, and on their subsequent capacity to keep sustaining the entire food chain that relies upon to them.</p> |
