We investigated the response of an alpine highly productive plant community to soil nutrient addition and irrigation. A 10-year experiment, including additions of calcium, phosphorus, nitrogen, phosphorus + nitrogen, and irrigation—was conducted in the northwestern Caucasus, Russia, at 2800 m above sea level. We found out that aboveground biomass did not change significantly. But the biomass increased by 25% in the case of the treatment with calcium addition compared with the control, also the… 
Seed reproduction traits of alpine plants depend on soil enrichment
The number of generative shoots was found to decrease in the majority of species, increasing only in Leontodon hispidus in Р and in Festuca varia in NP treatment, and Seed harvest increased significantly in four species.


Experimental Investigation of Fertilization and Irrigation Effects on an Alpine Heath, Northwestern Caucasus, Russia
The response of an alpine lichen heath plant community to an increase in soil nutrient and water availability in northwestern Caucasus, Russia is investigated, finding that plant density and flowering of the community is co-limited by nitrogen and phosphorus.
Effects of alleviation of ecological stresses on an alpine tundra community over an eight-year period
An eight-year field experiment in an alpine tundra in northern Sweden suggests that treatments which have vastly differing consequences for humus properties and the decomposer subsystem, but which alleviate an inherent stress, have similar consequences above-ground.
Nutrient availability, plant abundance, and species diversity in two alpine tundra communities.
Plant absolute abundance and species diversity to N, P, and N+P fertilization were investigated in two sedge-dominated alpine plant communities that differed in soil resource availability but not in macroclimate: a resource-poor dry meadow and a more resource-rich wet meadow.
15N abundance of soils and plants along an experimentally induced forest nitrogen supply gradient
In this experiment, 15N abundance increased with dose of N applied in both grass and soil total-N, but more so in the grass, which was interpreted to be due to the grass sampling small but active pools of N subject to losses.
Plant Species Richness, Productivity, and Nitrogen and Phosphorus Limitations across a Snowpack Gradient in Alpine Tundra, Colorado, U.S.A.
The extent to which nutrient limitation affects species composition, abundance, and productivity of the alpine tundra is an ongoing area of ecological inquiry. At Niwot Ridge in the Front Range of
Long term influence of fertilization in a Nardetum
The influence of the fertilization is visible in the species composition of the vegetation of the squares of the Geo montani-Nardetum, most clearly for the treatments with limestone.
The difference in community response to nutrient amendments was not the result of functional changes at the leaf level of the dominant species, but rather was related to changes in community structure in the dry meadow, and to a shift from a nutrient to a light limitation of production in the wet meadow.
Plant responses to fertilization and exclusion of grazers on an arctic tundra heath
The use of functional growth forms for predicting the responses of nutrient enrichment and grazing must be questioned, as responses to fertilization as well as preferences by herbivores were shown to be species-specific rather than uniform within functional groups based on plant growth forms.
Responses of moist non-acidic arctic tundra to altered environment: productivity, biomass, and species richness
The results suggest that in non-acidic tundra carbon sequestration in plant biomass will not increase substantially under increased soil nutrient conditions because of the lack of overstory shrub species.
Competition intensity and its importance: results of field experiments with Anthoxanthum odoratum
For Anthoxanthum the impact of competition is greater in high-productivity areas and that competition reduces population density, and no evidence was found supporting the importance of positive interactions between plants in tundra areas.
