Abstract What would current ecosystems be like without the impact of mankind? This question, which is critical for ecosystem management, has long remained unanswered due to a lack present-day data from truly undisturbed ecosystems. Using mountaineering techniques, we accessed pristine relict in Peruvian Andes provide this baseline and compared it with surrounding accessible disturbed landscape. We show that natural human high are radically different preconceived ideas. Vegetation these ‘lost...

Flourensia (Asteraceae, Heliantheae, Enceliinae) is an amphitropical genus of resinous subshrubs, shrubs and small trees with 13 North American 20 South species among which disagreement on the limits some members still exists. To resolve taxonomy taxa, we carried out a combination clustering (Ward's method Gower distance coefficient) ordination analyses (Principal Coordinate Analyses) based 34 vegetative reproductive characters scored from herbarium material, including types. Based results,...

Abstract The grass subtribe Loliinae has great ecological and economic importance, as it includes community-dominant species of world mountain grasslands the most extensively cultivated pasture, fodder lawn grasses (fescues, ryegrasses). Resolving phylogeny recently evolved lineages proven challenging due to frequent introgressions polyploidizations that occurred throughout their history. Evolutionary reconstruction based on genome-wide data sets is useful for large groups species, enabling...

This paper clarifies the typification of nine species Begonia from South America. Lectotypes were designated for names balansae, B. argentinensis [= boliviensis], boliviensis var. latipetala, subcucullata and cucullata arenosicola cucullata], fiebrigii, micranthera, hieronymi [=B. micranthera hieronymi] subvillosa. Finally, we propose as a new synonyms under cucullata.

The monophyly of Flourensia was examined for the first time by sequencing nuclear ITS and plastid psbA- trnH regions in 18 species genus, analyzing them along with representatives remaining genera subtribe Enceliinae. Results showed strong evidence polyphyly identifying two well-supported groups: Flourensia, a clade from North America including type F. laurifolia, another clade, here designed as new genus Austroflourensia, containing South American species. Austroflourensia is related to...

Abstract— A new species, Serpocaulon australe , from the Yungas Montane Forest of Argentina and Bolivia, is described based on a re-interpretation name S. gilliesii . The species similar to lasiopus but can be distinguished by its rhizome scales with entire margins acute-acuminate apices, glabrous fronds few axillary in segments, sori absent apex ascending segments. We investigated taxonomic relationships among these using morphoanatomical characters sporophyte ecological preferences....
