| expansion of green alder (alnus alnobetula [ehrh] k. koch) in the northern french alps: a palaeoecological point of view. | pollen analyses were undertaken on a small peat bog (ecuelles 06 degrees 49' 41''e, 45 degrees 58' 49''n, 1855 m asl), located on the anterne mountain (upper-arve valley, french north-western alps). the study highlights the role of green alder (alnus alnobetula [ehrh] k. koch) in holocene vegetation dynamics of the nowadays treeless subalpine belt. at this place, the onset of human perturbation caused a retreat of fir and arolla-pine stands and an expansion of green alder, which consequently dom ... | 2010 | 20451884 |
