BACKGROUND AND AIMS Soils of mountain regions and their associated plant communities are highly diverse over short spatial scales due to the heterogeneity of geological substrates and highly dynamic geomorphic processes. The consequences of this heterogeneity for biogeochemical transfers, however, remain poorly documented. The objective of this study was to quantify the variability of soil-surf...
Alpine areas worldwide are under heavy land-use pressure and degradation. Active restoration treatments can contribute to accelerating recovery of degraded areas. However, monitoring data needed understand the contribution long-term management predict time (TR). In this study, we used on removed roads in an alpine area Norway investigate TR three vegetation-based indicators. Four were tested: 1...
Question The Stress Gradient Hypothesis (SGH) predicts that competition and facilitation shift along stress gradients. We ask if the underlying mechanisms operate at specific points in plant life history, patterns are consistent different Location Boreal, sub-alpine alpine grasslands southern Norway. Methods test SGH through ontogeny gradients by monitoring seedlings intact vegetation vs bare-g...
The highest parts of the European mountain massifs are covered by subalpine and alpine vegetation, with rich flora containing many relic woody plants adapted to cold temperatures relatively short vegetation periods. In Ukrainian Carpathians, only several form environmental conditions suitable for high plants. aim study was detection centre biodiversity in East Carpathians Ukraine. We expected l...
This study examined the use of hyperspectral profiles for identifying three selected weed species in alpine region New South Wales, Australia. The targeted weeds included Orange Hawkweed, Mouse-ear Hawkweed and Ox-eye daisy, which have caused a great concern to regional biodiversity health environment Kosciuszko National Park. Field surveys using spectroradiometer were undertaken measure leaves...
