Abstract:
Bioparameters of selected herb
species were studied on five control (undamaged) and five bark beetles
damaged parallel plots established in form of two vertical transects in the spruce
ecosystems of Bielovodská valley (High Tatra Mts.). The most abundant life
forms in the studied phytocoenoses were hemicryptophytes (65%), the least
abundant geophytes (5%). According to significance of differences in the
average length of shoots the sensitivity of herb species to different
ecological conditions and calamitous changes of the spruce stands density is
as follows: Homogyne alpina >Luzula
sylvatica = Dryopteris dilatata >Oxalis acetosella. According to significance of
differences in energy content the sensitivity of species was following: Luzula sylvatica >Oxalis acetosella
>Dryopteris dilatata >Homogyne alpina >Vaccinium myrtillus.
However, the mean values calculated for undamaged and for damaged plots were
significantly different (P< 0.05)
only in the case of weight of Luzula
sylvatica shoots. |
