On community structure in high alpine grasslands

Vegetatio, 1989
Previously published data on production biology, energy use efficiency, nutrient availability and vulnerability were reinterpreted for the explanation of community processing and structure in high altitude grasslands of the Alps. The final goal of the approach was to present a characterization of these plant communities in generalized terms.

Sub‐alpine and alpine grassland communities in the northeastern Greater Caucasus of Azerbaijan

Applied Vegetation Science, 2015
AbstractQuestionsWhich are the main sub‐alpine and alpine grassland communities in the northeastern Greater Caucasus of Azerbaijan and what are their environmental and anthropogenic drivers?LocationGrasslands at 1800 and 3500 m a.s.l. on northern macroslope of the Greater Caucasus in Azerbaijan near Shahdag Mt.MethodsWe established a randomized ...

The ecology of some alpine grasslands

1968
The study of the ecology of the alpine grasslands of New Zealand is in its infancy and one of the lesser-known kinds of grassland is that dominated by the short grass Chionochloa oreophila (Petrie) Zotov. This grass lives near the upper limit of alpine vegetation, usually in hollows where snow lies late into the summer (frontis-piece).

Machine learning in soil nutrient dynamics of alpine grasslands

Science of The Total Environment
As a terrestrial ecosystem, alpine grasslands feature diverse vegetation types and play key roles in regulating water resources and carbon storage, thus shaping global climate. The dynamics of soil nutrients in this ecosystem, responding to regional climate change, directly impact primary productivity.

Alpine grassland degradation in the Qilian Mountains, China — A case study in Damaying Grassland

CATENA, 2016
Abstract Degradation of semiarid grassland and efforts to control that degradation have become pressing issues. However, the inherent characteristics of the grassland and the intertemporal nature of the problem complicate the analysis of degradation issues, and consequently, the search for more appropriate rangeland policies.

Soil Moisture Threshold of Methane Uptake in Alpine Grassland Ecosystems

Global Change Biology
ABSTRACTMethane (CH4) uptake in alpine ecosystems is an important component of the global CH4 sink. However, large uncertainties remain regarding the magnitude and spatial patterns of CH4 uptake, owing to its extensive spatial variability, diverse controlling factors, and limited regional‐scale observations.

Analysing the potential of multispectral sensors to map vegetation parameters in pre-Alpine and Alpine grasslands

2018
Pastures and natural grasslands are an important part of the pre-Alpine and Alpine landscape ranging from intensive grasslands in the lower regions to highly diverse seasonal mountain pastures and specialized natural ecosystems. Despite the economic value and the significant role of plants in grassland carbon (C) and nitrogen (N) cycling, spatially ...

Ecological applications of imaging spectroscopy in alpine grasslands

2015
Ecosystem ecology investigates the processes driving ecosystems, the services ecosystems provide and how these processes and services are linked to the organism community. However, due to the complexity of ecosystems and an inherent multitude of interactions, the links between ecosystem processes and services and the organism community are only partly ...

Effects of microbial agents on soil microecology of alpine desertified grassland and degraded grassland

Comprehensive Plant Biology
Desertified and degraded grassland can severely damage the soil microbial structure, accelerating desertification and degradation. Microbial agents can improve soil fertility, and even play a very important role in controlling soil desertification, promoting grass?land sustainability, and enhancing productivity.
