The paper presents a taxonomic, areographic and belt-andzonal analysis of the high-mountain flora Kurai Ridge. region in question contains 312 species plants, referred to 143 genera belonging 48 families. Analysis taxonomic structure Ridge has shown following most abundant plant families: Asteraceae , Ranunculaceae, Poaceae . For variety genera, are predominant: Carex Pedicularis, Salix Oxytrop...

1. Alpine plants are at high risk because of climate change. Assessing the performance of alpine plant species across different altitudes is useful for predicting how they may respond to changing climate. Adaptation and plasticity of early life stages are of particular interest since seed germination and seedling establishment could be crucial life-history stages for environmental tracking and ...

Qinghai-Tibet Plateau grasslands are unique geographical regions and store substantial soil organic matter (SOM) in the soil surface, which make them very sensitive to global climate change. Here, we focused on three main grassland types (alpine meadow, steppe, and desert) and conducted a soil incubation experiment at five different temperatures (5, 10, 15, 20, and 25°C) to investigate SOM deco...

Macaronesia, which includes five mid-Atlantic archipelagos (Azores, Madeira, Selvagems, Canaries, and Cape Verdes), has been traditionally recognized as a distinct biogeographic unit whose circumscription has been intimately associated with the hypothesis that the flora is a relict of a formerly broadly distributed subtropical Tertiary flora. The concept of Macaronesia is revisited here using p...

The Himalayan thar (Hemitragus jemlahicus Smith) is an introduced ungulate pest of the alpine zone in New Zealand’s Southern Alps. Considerable money is spent attempting to mitigate their effects on indigenous flora (Tustin, 1990). Current management focuses on maintaining thar densities below specified densities by a combination of recreational, commercial, and government-funded hunting (Depar...

bacterial culturability and abundance in an alpine soil. (manuscript) isolated from alpine and forest soils. Int. Dr. F. Gich has supervised the diploma-thesis from H. Hoffelner who has contributed the alpine soil sample, the data for the ATP activity in soil slurries, the data of the preliminary tests for detachment of soil bacteria from soil particles, and has produced the MicroDrop cultures....

Alpine regions are moving into the focus of scientific attention: chapter 13 of Agenda 21 is dedicated to mountains, 2002 was declared «International Year of the Mountain» and German Geographers' Day 2003 was entitled «Alpine World Mountain World: Islands, Bridges, Borders». The sustainable preservation of alpine regions represents a global issue, because a tenth of the world's population lives...

Soil freezing-thawing cycle may substantially influence soil physical properties, microbial activity, and the rates of carbon and nitrogen cycling in soils. In this study, the soil water soluble organic C, N (WSOC, WSON) as well as microbial biomass C, N (MBC, MBN) of two alpine grassland types, alpine meadow and alpine steppe, were investigated after freezing-thawing cycles in a grassland land...
