“…The speed of vegetation green-up increased in home ranges experiencing higher winter and spring precipitation, and in those located at higher elevations. This effect is consistent with results from other rangeland systems, and is likely due to a greater flush of available moisture for plant growth in the spring, thereby accelerating green-up of vegetation (Walker et al 1993;Walker et al 1995;Bjork & Molau 2007, Christianson et al 2013). …”

“…Home ranges with higher winter precipitation had significantly greater productivity (INDVI), probably because the greater moisture availability enhances vegetation growth throughout the spring, and potentially the summer if snowmelt continues into the middle part of the year (Walker et al 1993;Walker et al 1995;Bjork & Molau 2007). …”

“…Without the protection of snow cover, plants in these early-melting plots were exposed to cold nights when they underwent violent freeze-thaw alteration, and many of them could not tolerate such severe conditions and were eliminated from the community. Therefore, although a long growing season associated with early snowmelt was beneficial to many plants' reproduction and growth (Walker et al 1993, Galen and Stanton 19911993, the early-melting plots (of class I and class II) did not contain maximal number of species compared with other snow-depth classes. This was the reason why nocturnal low temperature was considered as one of the limiting factors on plant life and species richness in the alpine study area (Grabherr et al 1995, Odland and Birks 1999, Wohlgemuth 2002).…”

“…Billings and Bliss (1959) showed that floristic differences along a snow gradient resulted from differing tolerances of species to drought and shortness of growing season. Walker et al (1993) found that most plant species had an optimal range of snow depth, leading to dissimilar biodiversity between depth classes. Although snow cover plays an important role in structuring vegetation type as well as plant diversity in the alpine zone, there are, so far, few studies (WU 2005) on the relationship between snow cover and species diversity of the alpine meadows on the eastern Qinghai-Tibetan Plateau.…”

“…Snow is one of the most important factors controlling vegetation and ecosystem functions in higher latitudes and alpine areas (Walker et al 1993;Høye et al 2007). The duration of snow cover and snow cover thickness directly govern fluxes of CO 2 in plant communities (Grøndahl et al 2007;Larsen et al 2007;Nobrega and Grogan 2007;Grogan 2012) and in the colder regions, where the growing season is short, a few weeks of change in season length may have significant impact on phenology and ecosystem functions (Walker et al 1999;Høye et al 2007;Post et al 2009;Elmendorf et al 2012).…”
