| Title | PALEOLIMNOLOGICAL RECORDS OF CAROTENOIDS AND CARBONACEOUS PARTICLES IN SEDIMENTS OF SOME LAKES IN SOUTHERN ALPS |
| Abstract | Stratigraphic analyses of organic carbon, organic nitrogen and algal and bacterial carotenoids in short cores of profundal sediments of four alpine lakes (Tovel, Leit, Paione superiore and Tom) were used to reconstruct their trophic history. In addition, depth distribution of carbonaceous particle concentrations provided information on lake contamination from atmospheric deposition. |

In addition, depth distribution of carbonaceous particle concentrations provided information on lake contamination from atmospheric deposition. In three lakes Tovel, Leit and Tom , sedimentary carotenoids unique to sulfur photosynthetic bacteria okenone and isorenieratene provide evidence of changes in the oxygen, light and sulfide conditions in the water column. All the lakes are oligotrophic or moderately productive, and the algal community is dominated by Chlorophyta, Pyrrhophyta and Cryptophyta. Cyanobacteria are rather poorly represented. 274 Published version Articolo in rivista Kluwer Academic Publishers 0018 8158 Hydrobiologia The Hague. Print Hydrobiologia The Hague.
