WebEpiphytes of seagrasses include algae (micro and macro), bacteria, fungi, sponges, bryozoans, tunicates, protozoa, hydroids, crustaceans and mollusks. Of all of these, algae are the most abundant and diverse … WebEpiphyte microalgal assemblages were more abundant on the leaves of C. nodosa but more diversified on the leaves of P. oceanica . We suggest that the differences in species composition and abundance between those seagrass species may reflect an interaction of timescales of seagrass longevity with timescales of algal reproductive biology.

WebAug 27, 2013 · Seagrasses are a globally distributed group of marine angiosperms that provide valued ecosystem services, such as fueling secondary production, creation of habitat for many other species ( 9 ), shoreline protection, and carbon sequestration from the surrounding seawater and overlying atmosphere ( 8, 10 ). WebEpiphytes can therefore play an important role in the functioning of seagrass ecosystems. Neverthe less epiphytes on seagrasses in tropical regions remain poorly studied.

This comparison appears initially to be at odds with other published data sets as epiphytes are isotopically lighter than seagrass leaves [Moncreiff and Sullivan, 2001]. Webciated with patchy epiphytic algae within the meadows show spatial heterogeneity at the local scale. Spatial ho-mogeneity within the seagrass meadow reﬂects repetition of seagrass leaf substrate and microhabitats, and the uniformity of ambient environmental variables at scales larger than the seagrass leaves.
