Niche partitioning of intertidal seagrasses: evidence of the influence of substrate temperature

What is it about?

During low tide, surface sediments and seagrasses are exposed to heat stress from sunlight. Sediments heat at the surface and this heat is slowly transferred down into the sediments, leading to cooler temperatures at depth. We found that the below-ground structures (rhizomes) of some seagrasses grow at depths that decrease exposure to the temperature fluctuations observed at the surface.
