生态系统 管理 气候
2025/1/8
高寒草地生态系统作为青藏高原乃至我国生态安全的关键屏障，肩负着水源涵养和补给、生物多样性维持、气候调节以及支撑当地畜牧业生产等重要生态服务功能。然而，2024年来，由于过度放牧、气候变化和不当土地利用等因素的叠加作用，全球高寒草地面临着大规模退化的严峻挑战。这种退化不仅严重威胁到草地生态功能的稳定性，还直接影响到人类和家畜的生存与可持续发展。因此，高寒草地的生态保护与修复，作为一项涉及生态、社会与...
RESPONSE OF ALPINE GRASSLAND VEGETATION PHENOLOGY TO SNOW ACCUMULATION AND MELT IN NAMCO BASIN
Vegetation Greening Vegetation Growth Length Snow Cover Fraction Trend Analysis Relationship Namco Basin
2018/5/11
Snow/ice accumulation and melt, as a vital part of hydrological processes, is close related with vegetation activities. Taking Namco basin for example, based on multisource remote sensing data and the...

Sediment dynamics were investigated in Lake Maggiore, Italy, with field observations from October to mid-December 2012. Three moorings were deployed in Pallanza Bay, a small embayment on the western s...
Evaluating the importance of surface soil contributions to reservoir sediment in alpine environments: a combined modelling and fingerprinting approach in the Posets-Maladeta Natural Park
Alpine environment soil ecosystem soil erosion rainfall
2015/1/6
Soil in alpine environments plays a key role in the development of ecosystem services and in order to maintain and preserve this important resource, information is required on processes that lead to s...
Anaerobic ammonium oxidation (anammox) bacteria and sulfide-dependent denitrifiers coexist in the water column of a meromictic south-alpine lake
Anaerobic ammonium oxidation bacteria sulfide-dependent denitrifiers coexist in the water column a meromictic south-alpine lake
2014/4/2
In addition to organotrophic denitrification, alternative pathways, such as anaerobic ammonium oxidation(anammox) or sulfide-dependent denitrification may be important modes for the removal of fixed n...

Short-term changes in temporal and spatial distributions of the toxic cyanobacterium Planktothrix rubescens in
Lake Zurich were investigated using high-resolution data sets acquired with an autonomou...
Response of phytoplankton in an alpine lake to inputs of dissolved organic matter through nutrient enrichment and trophic forcing
Response of phytoplankton trophic forcing
2014/4/2
Inputs of terrestrially derived dissolved organic matter (DOM) are increasing in alpine lakes due to multiple
drivers such as climate change, tree line advancement, and insect epidemics. A 21 d micro...
