摘要: In the Mediterranean region temporary ponds are classified among most biologically and biogeographically interesting ecosystems. Despite their important ecological functions in those environments, bryophytes neglected or undervalued monitoring conservation actions. We analyzed data to understand if (i) environmental variables had an influence on composition of (dbRDA); (ii) there differences sites ponds, terms species (PERMANOVA); (iii) respond water table fluctuation, showing a typical small-scale spatial zonation comprehend life form/strategies belts (PCoA). Bryophytes distributed concentric (outer, central, inner) according tolerance floods: we observed gradient from outer belt, mainly composed by colonist perennial such as Pottiaceae Brachytheciaceae, more humid inner one where annual shuttle Ricciaceae dominates. found significant associated with belts, Tortella squarrosa Fossombronia caespitiformis central Riccia canaliculata belt. The presence indicator distribution dominant allow monitor over time changes flood level.
