Epiphytes seagrass
WebJan 1, 1975 · Epiphytes are distributed through the water column where they are advantageously exposed to light, nutrients and wave action. Nitrate and phosphate absorbed from leaves and roots of seagrass eventually leak into adjacent water where they are available to attached organisms before excessive dilution.

Richard … In our laboratory incubations, epiphytes accounted for 50% of P. oceanica leaf NPP under vent pH and 62% under ambient pH conditions. Several studies have found that epiphytes contribute up to 60% to photosynthesis and primary production for different seagrass species, such as Halodule wrightii, Syringodium … See more The relationship between decreasing pH and increasing production of P. oceanica has been investigated over a wide range of pH from 7.9 to 5.523,25,50, using a variety of methods. Other seagrass species, such as … See more P. oceanica meadows at the vent pH sites showed higher shoot density but shorter leaf length and width than at ambient pH sites (Suppl. Table 2).
