Changes in ecosystem service values in karst areas of China
Agriculture, Ecosystems & Environment, 2020Abstract Karst ecosystem services (ESs), the key components of global terrestrial ESs, play a crucial role in human welfare and livelihood. However, the spatiotemporal changes of ecosystem service values (ESVs) in the karst areas of China remain unclear. In this paper, land use/land cover (LULC) data were used to estimate the ESVs changes during 1992–

Soil Ecosystem Degradation of Karst Regions in Southwestern China
2012Deeply influenced by karst geological environment, the structure of the soil ecosystem in the southwest karst area of China is characterized by strong vertical variation and space variation, structural feature of nonrenewable soil, and functional feature of poor circulation of nutrient elements and limited vegetation growth.

Springs as Essential Water Sources for Dependent Ecosystems in Karst
2021The karst covers some 30% of the territory of former Yugoslavia and similarly Western Balkans countries and represent fully contrasted terrain. On one side there are dry hilly mountainous terrains with deep groundwater table and terrestrial ecosystems adapted to these circumstances while on another, in the foothills and along erosional bases are often ...

Karst springs - windows to the groundwater ecosystems health
Karst Science Days Symposium ProceedingsKarst aquifers are important sources of drinking water, however their characteristicsmake them highly vulnerable to the exponential increase of anthropogenic pressure (Onac & van Beynen, 2021). These aquifers consist of an interconnected network of pores, issures, fractures, and conduits with high permeability.

Benthic Macroinvertebrate Assemblages in Karst Springs Ecosystems in Bulgaria
2023Ecosystems of karst springs are insufficiently studied in Bulgaria. This study was focused on bottom macroinvertebrate assemblages from this river type. Their taxonomic diversity, community structure and habitat preferences in relation with the environmental factors were examined.

Nitrogen Leaching of Two Forest Ecosystems in a Karst Watershed
Water, Air, & Soil Pollution, 2010Karst watersheds are a major source of drinking water in the European Alps. These watersheds exhibit quick response times and low residence times, which might make karst aquifers more vulnerable to elevated nitrogen (N) deposition than non-karst watersheds. We summarize 13 years of monitoring NO 3 − ,

Soil bacterial community composition and diversity respond to cultivation in Karst ecosystems
World Journal of Microbiology and Biotechnology, 2011Soil microorganisms play vital roles in recovering and maintaining the health of ecosystems, particularly in fragile Karst ecosystems that are easily degraded after cultivation. We investigated the composition and diversity of soil bacterial communities, based on RFLP and 16S rDNA sequencing, in a cropland, a naturally revegetated land with former ...

Trade-offs among ecosystem services in a typical Karst watershed, SW China
Science of The Total Environment, 2016Nowadays, most research results on ecosystem services in Karst areas are limited to a single function of an ecosystem service. Few scholars conduct a comparative study on the mutual relationships among ecosystem services, let alone reveal the trade-off and synergic relationships in typical Karst watershed.

Land use in karst terrain: review of impacts of primary activities on temperate karst ecosystems
2002(Uploaded by Plazi for the Bat Literature Project) There is an acknowledged lack of information available to managers of New Zealand's karst estate on the impacts of primary activities on these sensitive environments. A review of the international literature was undertaken to begin to address the issue.
