Última New distributional records for Chilean bryophyte and lichen flora Gayana Botánica León,Carolina A; Oliván,Gisela; Pino-Bodas,Raquel. Ten new distributional records to the Chilean bryo-lichenic flora are reported. Three species and a subspecies are new to the flora of the province of Chiloé, five species are new from the Los Lagos Region and one species is new to mainland Chile. The specimens were collected in peatlands (Sphagnum bogs) and swamp forests of Tepualia stipularis in Isla Grande de Chiloé (Chile) (41°- 43° S; 74°-73° W). Diagnostic characters, chemistry (only lichens), habitats preferences and distribution are provided. The national ranges of two species are expanded.

BACKGROUND: Peatlands play a key role in the global carbon cycle; these contain one third of the world's soil organic carbon, equivalent to more than half the amount of carbon in the atmosphere. Nevertheless, these ecosystems have been scarcely studied in southern South America. The main objective of this paper is to evaluate the recent accumulation rates of carbon (C) and nitrogen (N) in two kinds of oligotrofic peatlands in Isla Grande de Chiloé (Chile). RESULTS: Using peat C and N content, dry bulk density, and Pb-210 dating, we determined the rates of N and C accumulation in profiles from five peatlands in the northern Chilean Patagonia. The recent rate of C accumulation (RERCA) ranges from 8.5 to 87.06 g C m-2 year-1, and the recent rate of N...
