Hubanova N. Dynamics, diversity, stability of amphibian communities and their functional role in forest biogeocenoses of the river Samara valley.

The object is amphibian communities of forest ecosystems of the river Samara valley. The aim is to establish the laws of dynamics and diversity of amphibian communities of forest ecosystems of the river Samara valley, to assess the sustainability performance communities and determine the nature of the dynamics pedoturbation edafic properties due to digging activity of amphibians. The methods are field, statistics. Dynamics and a diversity of amphibian communities of valley of the river Samara forest biogeocenoses have been established in dissertation.Indicators of community stability have been estimated. The essence of edafic properties pedoturabation dynamics owing to amphibians digging activity have been defined. Four species of anura (Pelobates fuscus, Rana arvalis, Bombina bombina and Bufo bufo) have been found to be presented in forest biogeoceonosis of the river Samara valley among which Pelobates fuscusis dominant. Application spheres are biodiversity monitoring, environmental impact assessment, the training courses.
