DIGITAL EXTRACTION AND CHANGE ANALYSIS OF ALTITUDINAL NATURAL ZONES IN TIANSHAN TOMUR NATURAL HERITAGE SITE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
The Tomur Natural Heritage Site possesses the most typical altitudinal natural zones on the south slope of the Tianshan Mountains. Five altitudinal zones have developed on the south faced slope, including: warm temperate desert zone, mountain steppe zone,

UV-B Radiation Effects on the Alpine Plant Kobresia humilis in a Qinghai-Tibet Alpine Meadow. [PDF]

open access: yesPlants (Basel), 2022
Enhanced UV-B radiation resulting from stratospheric ozone depletion has been documented both globally and on the Qinghai-Tibet Plateau in China. The response of Kobresia humilis, an important alpine meadow plant species, to enhanced UV-B radiation was experimentally investigated at the Haibei Alpine Meadow Ecosystem Research Station (37°29′–37°45′ N ...

Wood Microsites at Timberline-Alpine Meadow Borders: Implications for Conifer Seedling Regeneration and Alpine Meadow Conifer Invasion

open access: yesNorthwest Science, 2013
Abstract The importance of climate warming on forests is recognized worldwide and has increased attention on the significance of both timberline advance and alpine meadow invasion by forests. Successful seedling regeneration in alpine meadows depends on availability of suitable substrates, or microsites, for seedling establishment.

The Great Caucasus alpine belt syntaxonomy. Alpine meadows with restricted distribution

open access: yesVegetation of Russia, 2001
Alpine meadows with prevalence of perennial herbs and grasses and alpine fruticose-lichen heaths are widespread within the Great Caucasus alpine belt, 2400—3200 m above the sea level. The association Hedysaro hedysaroidis—Campanuletum collinae is met in the Western and Central Caucasus.

Symbiotic nitrogen fixation by legumes in two Chinese grasslands estimated with the (15)N dilution technique [PDF]

open access: yes, 2011
Symbiotic nitrogen (N) fixation by legumes was investigated using the (15)N dilution technique in two Chinese grasslands: one in the north-eastern Tibetan Plateau and the other in Inner Mongolia in China. A small amount (0.03 g N m(-2)) of (15)N labelled

Facultative Altitudinal Movements by Mountain White-Crowned Sparrows (Zonotrichia Leucophrys Oriantha) in the Sierra Nevada [PDF]

open access: yes, 2004
Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) winter in Mexico and often arrive in the vicinity of their breeding grounds in the Sierra Nevada well before nesting is possible.

Sphingomonas prati sp. nov., isolated from alpine meadow soil

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2016
A Gram-staining-negative, non-motile, orange-coloured and rod-shaped aerobic bacterium, designated W18RDT, was isolated from the alpine meadow soil of the Tibetan plateau. Phylogenetic analysis based on 16S rRNA gene sequences positioned strain W18RDT as a representative of a novel species under the genus Sphingomonas which was most closely related to ...
