Quantitative ecological relationships in the alpine grassland of Lesotho*

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1974
A survey, based on 56 000 points at 102 sampling sites in the Tsehlanyane valley of the Oxbow (Madibamatso) Dam catchment in the alpine grassland of Lesotho, indicates that the area is generally in good condition. Physiographic and floristic criteria were measured and the association between pairs of criteria statistically tested. The simple (126 spp.)

Functional diversity and grazing intensity in sub‐alpine and alpine grasslands inAndorra

Applied Vegetation Science, 2014
AbstractQuestionsHumans are altering land use and impacting grazing intensities worldwide in alpine and sub‐alpine grasslands, and functional diversity (FD) is a useful tool for predicting changes in these grassland communities and for improving biodiversity conservation.

Challenges facing alpine/ mountain grasslands

This chapter reviews the main characteristics of grasslands in mountain areas. The challenges for grassland farming are mainly related to topographic features and to productive and socioeconomical issues. These challenges strongly limit management options, which often leave grasslands as the only possible agricultural land use and livestock farming as ...

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.

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 ...
