  Plant macrofossils from the “Mamontovy Khayata” permafrost sequence (71°60′N, 129°25′E) on the Bykovsky Peninsula reflect climate and plant biodiversity in west Beringia during the last cold stage. 70 AMS and 20 conventional 14 C dates suggest sediment accumulation between about 60,000 and 7500 14 C yr B.P. The plant remains prove that during the last cold-stage arctic species ( Minuartia arctica , Draba spp., Kobresia myosuroides ) coexisted wit…

  The pine forests of the Rhone Valley are severely damaged. Possible causative agents are fluoride and other harmful gases such as S02, HCl and NOx in the emissions of nearby aluminium smelters and chemical plants. Drought and aging may also have contributed to the damage. Core samples and trunk discs from damaged and undamaged Stands near Martigny were investigated using annual ring analysis. After Visual dating of the samples by means of «pointe…
