The paper gives a survey of biodiversity of planted grand fir (Abies grandis) stands in Rogów Arboretum on the background of environmental data compared to those of its natural distribution. Some information concerns studies on grand fir plantations in Europe and their influence on chosen components of the ecosystem. During the study, 63 taxa of vascular plants, mosses and liverworts, 46 taxa of fungi...
The paper gives a survey of biodiversity of noble fir (Abies procera) stands in Rogów Arboretum on the background of environmental data. Noble fir is native to the mountains of north-western United States. During the study in the Rogów Arboretum we have found 53 taxa of vascular plants and mosses, 51 taxa of macrofungi and 112 of invertebrates in Abies procera stands. The documented biodiversity of...
The purpose of this study was to examine how stand age affects fine root biomass and morphology in different stages of first generation Scots pine forest development in post-agricultural fields. Stands of different ages (6-, 10-, 16-, 28-, and 47-yr-old) were studied at the same time to provide data on biometrical fine root features, i.e. biomass, length, surface area, volume, number of tips, root...
The morphology of fine roots ( 2 mm diameter) as well as fine and coarse root biomass was investigated in a chronosequence consisting of 6-, 9-, 11-, 15-, 17- and 20-year-old Scots pine (Pinus sylvestris) stands growing on a reclaimed lignite mine spoil heap. Core method of destructive root sampling was used to establish whether root morphology and biomass varied with stand age in the upper 20 cm...
Differentiation in the size and number of seeds among populations or particular individuals of a given species may depend on genetic features and environmental conditions. The objective of our study was to answer two questions: whether any differences exist in the size and shape of utricles among Carex spicata populations growing in several plant communities and whether the hypothesized differences...
“Uroczysko Wielkie Łunawy” belongs to objects which can be distinguished for their considerable floristic values. Varied and slightly deformed flora of this small object comprises 192 species of vascular plants derived from 60 families, including 41 taxons of arborescent plants. Sites of 13 species under legal protection were identified. Valuable fragments of oak-hornbeam and riparian forest communities...
