The aim of this study was to: 1) describe the genetic structure of the population of old Picea abies trees in the Białowieża Primeval Forest and 2) design the genetic database for every examined tree in scope of 26 isoenzymatic loci containing: the genotype pattern, the number of stated alleles and the level of individual heterozygosity. We found that 101 out of 117 trees are characterized by a unique...
The paper presents preliminary results and experiences concerning promoting diverse structures in forest stands dominated by light demanding tree species, i.e. those that prevail under conditions of Polish lowlands. Data was collected in the ‘Control Unit Browsk 28C', established in 2002 in the managed part of the Biało− wieża Forest (eastern Poland) and surveyed again in 2011.
The paper presents an analysis of abundance of the millipedes (Diplopoda) in the Białowieża Forest (eastern Poland) regarding habitat moisture and fertility. Mean individual biomass depends mostly on habitat fertility achieving higher values on eutrophic and moist sites. PCA and RDA confirmed observed pattern of relationship between millipedes abundance and site conditions.
