What does a phytophysiognomic mosaic reveal about mosses and liverworts from the subtropical Atlantic Forest?

The Atlantic Forest contains more bryophyte species and greater endemism than any other Brazilian phytogeographic domain. We analyzed the bryoflora of an remnant along southern coast to examine: (i) floristic composition, richness, life forms bryocenological groups in different phytophysiognomies (humid lowlands, sandy Restinga forests, swampy forests); (ii) similarities among them; and, (iii) influence substrate types on richness composition. Sandy forest had greatest richness. Approximately 75 % 42 families were not shared phytophysiognomies. predominant form was mat (46 %) group corticolous (69 %). Elevated differentiation observed (Jaccard values <0.35) substrates sampled (<0.2). uniqueness found physiognomies present study demonstrates importance studying diversity conservation all evaluation bryophytes delimit manage protected areas can contribute effective protection entire biodiversity spectrum. In addition their important ecological roles, are useful bio-indicators valuable tools for monitoring, conserving, restoring ecosystems.
