Shrubs have been reported to expand into grassland and polar regions in the world, which causes complex changes in ecosystem carbon, nutrients, and resilience. Given the projected global drying trend, shrubs with their superior drought resistance and tolerance may play more important roles in global ecosystem function. Shrubland exists in all of the climate zones in China, from subtropical to t...

[1] We investigated how the source and chemical character of aquatic dissolved organic carbon (DOC) change over the course of the runoff season (May–November, 1999) in Green Lakes Valley, a high-elevation ecosystem in the Front Range of the Colorado Rocky Mountains. Samples were collected on North Boulder Creek from four sites across an alpine/subalpine ecotone in order to understand how the tr...

Understanding the environmental factors determining the distribution of species with different range sizes can provide valuable insights for evolutionary ecology and conservation biology in the face of expected climate change. However, little is known about what determines the variation in geographical and elevational ranges of alpine and subalpine plant species. Here, we examined the relations...

Subalpine grasslands are highly seasonal environments and likely subject to strong variability in nitrogen (N) dynamics. Plants and microbes typically compete for N acquisition during the growing season and particularly at plant peak biomass. During snowmelt, plants could potentially benefit from a decrease in competition by microbes, leading to greater plant N uptake associated with active gro...

This note is the first communication of the occurrence of the alien Anodonta (Sinanodonta) woodiana (Lea, 1834) (Bivalvia: Unionidae) in Lake Maggiore (Northern Italy). We have found empty shells of the bivalve first in August 2010, and since then, this species is colonizing rapidly the second deepest subalpine lake in Italy. Preliminary findings on morphometric features of A. woodiana in the L...

12 [1] We investigated how the source and chemical character of aquatic dissolved organic 13 carbon (DOC) change over the course of the runoff season (May–November, 1999) in 14 Green Lakes Valley, a high-elevation ecosystem in the Front Range of the Colorado Rocky 15 Mountains. Samples were collected on North Boulder Creek from four sites across an 16 alpine/subalpine ecotone in order to unders...

Cypripedium tibeticum, a subalpine orchid species, inhabits various habitats of subalpine forests, mainly including the forest edge (FE), forest gap (FG), and understory (UST), which have significantly different light intensities (FE > FG > UST). However, the ecological and physiological influences caused by different light regimes in this species are still poorly understood. In the present stu...
