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). Increased shoot density and shorter … See more WebEpiphytes can therefore play an important role in the functioning of seagrass ecosystems. Neverthe less epiphytes on seagrasses in tropical regions remain poorly studied. From the tropical East African coast almost nothing is known on the species composition of the seagrass epiphyton.
