Ies, and related photoautotrophs. Environmental circumstances in the sort locality: Discharge (L s-1): three.five, Temperature ( C): five.3, conductivity ( cm-1): 62, alkalinity ( q L-1): 311, pH: 6.6, nitrate (mg L-1): 1.two, TP ( L-1): 7 (see [1] for additional facts). As concerns photoautotrophs, in this quite shaded supply the competitive balance among substantial groups (algae, lichens, bryophytes, and vascular plants) is clearly favorable to the mosses, which cover nearly all the lithic substrata [dominance of Brachythecium rivulare W.P. Schimper, each submerged and, in massive portions, RWJ22164 (acetate) GPCR/G Protein emerged, plus a particular relevance of Plagiomnium undulatum (Hedw.) T.J. Kop. and Rhizomnium punctatum (Hook.) T.J. Kop.]. Vascular plants will not be abundant (as cover), and Adenostyles glabra (Miller) DC. and Saxifraga rotundifolia L. may be mentioned among them. With regards to cover, bryophytes are followed by lichens. These contain two species which are seldom reported in Italy: Verrucaria madida Orange, an amphibious species in often flooded internet sites on siliceous rocks, usually in association with other aquatic lichens and bryophytes, and Verrucaria aquatilis Mudd., popular both in springs and along streams, in conditions of perennial/frequent submersion. Benthic macroalgae are uncommon and primarily represented by the red freshwater alga Hildenbrandia rivularis (Liebmann) J. Agardh, that is characteristic of shaded springs with well-buffered waters and medium-high conductivity.
