Wrack inputs can supply the bulk or sole source of primary production on some beaches and can provide an important potential food source and site for nutrient regeneration. In this chapter, the incorporation of wrack into beach and nearshore ecosystems was assessed via two pathways; decomposition and incorporation into trophic webs. Wrack decomposition was assessed using litterbags containing w...

Rinodina is a lichenized fungal genus belonging to the Physciaceae, with c. 300 species worldwide. Nearly century ago, Zahlbruckner described five of from Southwest China. The type collections were only records for these species. In present study, new four species: cornutula, R. globulans, handelii, and setschwana, recently species, pluriloculata, are documented based on specimens collected hol...
