Biogeomorphology and contingent ecosystem engineering in karst landscapes
Progress in Physical Geography: Earth and Environment, 2016While karst is not biogenic in the same sense as, say, coral reefs or peat bogs, and carbonate dissolution can occur abiotically, formation of karst landscapes would not occur in the absence of the biosphere. Seven levels of biogeomorphic biotic-abiotic interactions are identified, from indirect impacts to landforms as extended phenotypes.

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.

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 − ,

A review of village ecosystem services and insights into karst desertification control
Journal of Environmental ManagementVillage ecosystems (VEs), as small-scale interaction units between humans and nature, play a crucial role in sustainable development by providing ecological services to support residents' production and life and to cope with ecological and environmental problems. Karst desertification (KD) hinders the sustainable development of karst areas, and village

Characteristics of Karst Ecosystems of Vietnam and Their Vulnerability to Human Impact
Acta Geologica Sinica - English Edition, 2001AbstractKarst in Vietnam covers an area of about 60,000 km2, i.e. 18 % of the surface of the country. The country has an annual average temperature of 24°C, an annual average rainfall of 2300 mm and a relative humidity of about 90%. Karst in Vietnam is typified by peak cluster‐depression landscapes ranging in elevation from 200 to over 2000 m.

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.

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.

Sustainability of freshwater salmonid farming in a karst river ecosystem
2019Eutrophication in freshwater ecosystems is one of the major environmental problems. Aquaculture industry is greatly impacting aquatic environments by introducing nutrients and microorganisms through nutrient enrichment of water column and sediment. The aim of this research was to evaluate the impact of a salmonid farm on the environment.

Journal of Environmental Management
Within ecosystems, habitat influences structure, and structure determines function, forming a habitat-structure-function framework (HSFF). Net ecosystem productivity (NEP) is a key indicator for assessing regional or global carbon dynamics. However, the response thresholds of NEP to habitat and structural factors, along with management strategies based
