Influence of tectonic faults on the conditions and properties of some components of a biogeocenosis in a subarctic area
In geoecology, the nature of the effect of tectonic faults on the environment is not well studied. The influence of natural landscapegeochemicalfactors on the state and properties of some components of biota of different hierarchical levels is studied at the intersection oftwo tectonic faults (Velsk...

In geoecology, the nature of the effect of tectonic faults on the environment is not well studied. The influence of natural landscapegeochemicalfactors on the state and properties of some components of biota of different hierarchical levels is studied at the intersection oftwo tectonic faults (Velsko-Ust’yanskiy tectonic knot (TK)) in the Arkhangelsk region. Two species of shrubby lichens (Cladonia stellaris Opiz.and Usnea subfloridana Stirt.) and woody plants (spruce – Picea abies L. and Scots pine – Pinus sylvestris L.) were chosen as test systems. Thefield studies were carried out at nine test sites (in the centre, on the periphery and some distance from TK – the background reference point)in different types of forest. The ash content of samples of the lichen Cladonia growing in the centre of the TK (1.12–1.22%) is double that in thecontrol area (0.56–0.58%), and for the lichen Usnea, it is seven times higher (6.82–6.99% at the centre and 0.97–1.09% in the control area).
