Along precipitation gradients grasslands are located between forests and deserts. Grassland Ecosystem : Essay on Grassland Ecosystem! The parent material is often composed of fine sediments, and grasslands are most often in valley or plateau landscapes. 1996 , White et al. Task sheet. In grasslands, the accumulation of organic matter is much more intensive. Grasslands are very diverse in terms of management, yield and biodiversity value. In contrast, both the above and belowground biomass were significantly decreased in the area that soil layer thickness is 3 - 5 cm only over burrows in which have been used continually in all season. Plant and animal Alpine meadows are extensively distributed in the northern Tibetan Plateau and are typical features of the region. It was concluded that the community' s characteristic values under low plateau pika disturbance intensity were high but the grazing quality was low, while high disturbance intensity resulted in the grassland degradation. The nature of grass litter and its pattern of decomposition commonly result in the development of a dark, organically rich upper soil layer that can reach 300 millimetres below the surface. ADVERTISEMENTS: The annual rainfall ranges between 25- 75 cm, usually seasonal. The grassland ecosystem occupies about 25% of the total land area throughout the world. Biome Notes 1. We examined the soil organic carbon content of natural alpine meadow, degraded meadow, artificial pasture and farmland, and estimated the potential of carbon sequestration of the latter three types based on former natural alpine meadow. In addition, the effects of temperature and precipitation on the soil meso- and microfauna community also implies increased global temperatures will have adverse short-term effects on soil fauna in the alpine meadow ecosystem. extend the pilot study on grassland ecosystem services which was elaborated in 2010. Within the grassland ecosystem are enormous numbers of very small organisms, including bacteria, fungi, algae, and viruses. They usually get more rain than grasslands. Introduction. The grasslands in North America are called prairies. It is found where rainfall is about 15-75 cm per year not enough to support a forest, but more than that of true desert. The relative abundance of herbivorous to omnivorous and/ or predatory nematodes obviously varied in different plant communities. A grassland ecosystem is the collection of plants, animals and micro-organisms that live within an environment where grasses are the primary form of vegetation. Over 1 million visitors annually enjoy the ecosystem services provided on the National Grasslands. ADVERTISEMENTS: The annual rainfall ranges between 25- 75 […] There are lots of similarities between improved grassland and enclosed farmland. stream This lesson introduces the concept of how populations, communities, and nonliving physical elements combine to create an ecosystem. A perfect review and reinforcement tool that is a one page worksheet consists of 12 open ended questions on grassland ecosystems. Grassland ecosystems in British Columbia generally occur in areas where the climate is hot and dry in summer and cool to cold and dry in winter. The last decade has seen much progress in our understanding of C 4 grass ecophysiology, C 4 grassland ecosystem ecology and geologic history, and the evolutionary history of the C 4 pathway within the grass lineage. Diverse types of animals can be found in forests, depending on their type. When the disturbance was small, the community had high quantitative values of coverage, aboveground biomass, biodiversity, and species richness, but the proportion of weeds was also high. Land-based ecosystems include forests and grasslands. Copy of The Prairie Grassland Ecosystem Copy of Apply Your Knowledge . iefly on the high central plateau of South Africa, and the inland area of KwaZulu-Natal and the Eastern Cape. They occur in regions too dry for forests and too moist for deserts. • Grasslands form a variety of different ecosystems located in different climatic conditions, ranging from near-desert conditions to patches of Shola Grasslands that occur on the hill-slopes along side the extremely moist evergreen forests in South India. C cycling and Net Biome Productivity in grasslands • Soil C and land management •CO2 fluxes • Farm gate budget and mitigation options • Upscaling to regional scale Conclusions. Among these are: • WATER The storage, cleansing and distribu-tion of available water resources are the most important services pro-vided by grasslands. A total of 33038 nematodes, which were classified to nematode phylum, 2 classes, 6 orders, 51 families and 93 genera, were collected during the surveys. It offers an up-to-date review of the recent advances in grassland research in China, discusses the climatic and physical conditions governing the grasslands, describes their types and distribution, and introduces a new classification scheme for grassland ecosystems. Providing hay and honey There are many ways for direct use of grassland products, which can be collected, Grasslands also support biodiversity and cultural services and are an important stock of carbon. Grassland ecosystem is a type of terrestrial ecosystem with an open land of grasses. Grassland ecosystems occur in areas of the world that have an annual precipitation between 150 and 1200 mm and mean annual temperature between 0 and 25 1C(Whittaker, 1975). Six 50 m × 50 m plots were established using permanent markers. The following soil chemical properties were tested: pH, potentiometry, soil water content (oven drying method), and electricity conductivity. 5 0 obj Grassland ecosystem study. Soil fauna play an important role in terrestrial ecosystems, directly or indirectly modulating the availability of resources for other species by changing biotic or abiotic materials. Grasslands have been playing a prominent role in biodiversity–ecosystem functioning research. Correlation of nutritional groups and environmental factors showed omnivorous/ predatory nematodes were affected significantly by water content during dry periods, while a close relationship was found between soil pH and fungivorous nematodes, which was obviously affected by electrical conductivity (EC) during periods of rapid growth. A grassland ecosystem is the collection of plants, animals and micro-organisms that live within an environment where grasses are the primary form of vegetation. But whatever above and belowground biomass greatly decreased in the overlying vegetation of burrows where plateau zokors colonized over 10 years in which the vegetation was obviously different with surrounding environment. 2011).Extensively managed grasslands are recognized globally for their high biodiversity (Habel et al. The results indicated the hypothesis that the excavation under ground by plateau zokor caused negative effect for the dicotyledons of taproots, but could promote the growth and development of the monocotyledons to some extent was correct. The nature of the ecosystem is based on its geo-graphical features such as hills, mountains, plains, rivers, lakes, coastal areas or islands. In natural grasslands, effects of warming on net ecosystem CO 2 exchange (NEE) may interact with grazing. Examples of grassland ecosystems include the prairies of western North America, the Pampas of Argentina and the Russian steppes. However, how the spatial variation of Rs and Q10 changes with abiotic and biotic factors across Chinese grasslands and their differences among grassland types still remain poorly understood. Altitude varies from near sea level to 2,850 m above sea level. Types of Grasslands. The landscape approach to conserving biodiversity in 18 working landscapes 3.2. INTRODUCTION Grasslands have historically been an area of expansion for human land use (White et al., 2001), and much of the world’s highly productive grassland has been converted to The answer is – there are 11 major grasslands in the world. Grasslands in Africa are called veldts and savannas--together, they cover almost half of the continent. Global Distribution of Grasslands and Grassland Soils. 6 major terrestrial (land) biomes – tundra, boreal forest, deciduous forest, tropical rainforest, grassland, desert 3. Grassland Ecosystem - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. In Europe and Asia, they are called steppes, and in South America, they are the pampas. Herbivorous and bacterivorous nematodes were the major nematode communities in the area. A typical alpine meadow in Zoigê County grassland located on the eastern edge of Qinghai-Tibet Plateau, China, was studied to document the composition, diversity, and seasonal variations of soil meso- and microfauna communities in alpine grasslands. The results showed that the above and belowground biomasses of dicotyledons were obviously decreased at first colonizing, and the biomasses of monocotyledons over burrows in which the excavated soil was backfilled was significantly increased in primary vegetation. The grassland ecosystem itself influences soil formation, and this causes grassland soils to differ from other soils. Grasslands occupy about 24% of the earth’s surface. PDF (7.61 MB) Enhance your ecosystem unit while providing an engaging learning experience for all of your various types of learners. Grazing is the main land use in natural and semi-natural grasslands and has a great impact on soil carbon pools (Derner et al., 2006; McSherry et al., 2013; Luo et al., 2015). Canada’s grasslands, this ecosystem supports an astonishing diversity of species; the African savanna, for example, is home to some of the world’s most iconic mammals, including giraffes, zebras, and lions. While the ecosystem was resistant to heat waves, it was not resistant to extreme drought, which reduced aboveground net primary productivity (ANPP) below the lowest level measured in this grassland in almost 30 years. The results showed that with the increase of the disturbance intensity, the dominant species changed from Juncus roemerianus to Poa pratensis and Laux maritima. The results were mostly within the scope of previous reports, and nematodes obviously appeared to aggregate in the upper soil layers. GRASSLAND ECOSYSTEMS EVS PPT 1. regulatory framework influencing the maintenance of grassland ecosystems in the Baltic States, evaluated existing experience in grassland management and studied best practice examples.

All Important grasslands around the world pdf > Remembering all the grasslands is common general knowledge for any competitive examinations like IAS, UPSC, SSC, CGL, Railway PSC, and Banking. Grassland Ecosystem: Grasslands occupy about 19% of the earth’s surface. The major grassland ecosystems of the world are the great plains of Canada and United States, S. Argentina to Brazil and S. Asia to Central Asia. The results showed that the four vegetation types have a great difference in potential of carbon storage of 0-40 cm soil layer: (1) the carbon storage in natural alpine meadow was the highest with 17098 g C/m 2, and were 5637, 3823 and 1567 g C/m 2for degraded meadow, artificial pasture and farmland, respectively; (2) soil organic carbon content and density in degraded meadow and artificial pasture were significant lower than those in natural meadow and farmland; (3) root carbon storage mainly concentrated in the 0-20 cm topsoil, and the natural alpine meadow was 3. It is Fig. Biome – has similar climate and plant and animal life. The research indicated soil nematode tropic composition varied from one plant community to another in alpine meadows. What Are Grassland Ecosystem Services Worth? The trophic composition, c-p group structure and functional structure index, as well as the characteristic values between trophic groups, c-p groups and soil properties, were analyzed to understand the effect of cold alpine conditions on soil nematode functional diversity. 3.1 CONCEPT OF AN ECOSYSTEM An ‘Ecosystem’ is a region with a specific and recognizable landscape form such as forest, grassland, desert, wetland or coastal area. The nature of grass litter and its pattern of decomposition commonly result in the development of a dark, organically rich upper soil layer that can reach 300 millimetres below the surface. That pilot study explained the choice of grasslands as a model ecosystem due to the importance which grasslands play in the European Union from the perspective of economy and EU budget as well as due to the long in tradition in agricultural management. Grasslands experience cooler dry season temperatures than savannas. In order to explore the impacts of plateau pika disturbance on the alpine grassland ecosystem and its grazing quality, the community characteristics under different disturbance intensities by plateau pika were analyzed, and a conceptual model about the alpine grassland community succession was proposed. Grassland ecosystems are present in every single continent on this planet with the sole exception of Antarctica, which is too cold to sustain a grassland ecosystem. Well, this is the most common question for an aspirant. These ecosystems may return to their pre‐disturbance state after disturbance ceases; however, humans have altered the environment in ways that may change the rate or direction of this recovery. ...

EFFORTS BY: SAHIL SINGAL RIDHIT SHARMA RATTAN RASHI 2. m-2, and the ratio of aboveground biomass to belowground biomass was 1:4.5, 1:7.0, and 1:25.9, respectively, suggesting that grazing pasture was characterized by less plant species and more underground biomass production, while forage grassland was beneficial to the maintain of high species diversity and high and stable biomass production, being worthy for promoting the grassland restoration in the studied area. The answer is – there are 11 major grasslands in the world. An analysis of the constitution of the c-p groups showed all cp2 groups were the predominant groups in all three plant communities, and all c-p groups were mainly r-strategists. 1 Main ecosystem services of grasslands and their interactions with the grassland landscape and human needs (Modified from Campbell et al. Grassland Ecosystems in South Africa 13 2 3.1. These ideas are introduced by using the prairie grassland ecosystem as a specific example. In North America, South America and Asia, clear E–W precipitation gradients exist. However, the effect of grassland degradation on ecosystem services and the consequence of grassland deterioration on economic loss still remains a mystery. Printed The plots are situated at Dejixiangdaga village at N31°3138{double acute accent}-31°32′02{double acute accent}, E92°04′03{double acute accent}-92°04′16{double acute accent} in Naqu County in the Naqu region of the Tibet Autonomous Region, China. Differences in nematode community structure in different meadows preliminarily indicate the potential for using nematodes as environmental indicator species. ADVERTISEMENTS: Types of Ecosystem: Grassland, Forest, Desert and Cropland Ecosystem! It also summarizes the standing crops of canopy and root biomass and their allocation pattern of certain important communities. Kobresia pygmaea was the most common food source for nematodes. To be honest, the present grassland ecosystem as such has developed in the Baltic Region and most parts of Europe as a symbiosis between nature and man – disturbances provided by haymaking or grazing prevented grasslands from being overgrown by trees and bushes, and from reaching their final transformation back into forests.

What Are Grassland Ecosystem Services Worth? The trophic composition, c-p group structure and functional structure index, as well as the characteristic values between trophic groups, c-p groups and soil properties, were analyzed to understand the effect of cold alpine conditions on soil nematode functional diversity. 3.1 CONCEPT OF AN ECOSYSTEM An ‘Ecosystem’ is a region with a specific and recognizable landscape form such as forest, grassland, desert, wetland or coastal area. The nature of grass litter and its pattern of decomposition commonly result in the development of a dark, organically rich upper soil layer that can reach 300 millimetres below the surface. That pilot study explained the choice of grasslands as a model ecosystem due to the importance which grasslands play in the European Union from the perspective of economy and EU budget as well as due to the long in tradition in agricultural management. Grasslands experience cooler dry season temperatures than savannas. In order to explore the impacts of plateau pika disturbance on the alpine grassland ecosystem and its grazing quality, the community characteristics under different disturbance intensities by plateau pika were analyzed, and a conceptual model about the alpine grassland community succession was proposed. Grassland ecosystems are present in every single continent on this planet with the sole exception of Antarctica, which is too cold to sustain a grassland ecosystem. Well, this is the most common question for an aspirant. These ecosystems may return to their pre‐disturbance state after disturbance ceases; however, humans have altered the environment in ways that may change the rate or direction of this recovery. ...

Aesthetic beauty is one example of an ecosystem service provided on the grasslands for which there is no substitute. Semi-Arid Zone. In addition, it expounds on the succession characteristics and their responses to the management and utilization steps of certain typical steppe ecosystems. ADVERTISEMENTS: The various components of a grassland ecosystem […] Grasslands (also called Greenswards) are areas where the vegetation is dominated by grasses and other herbaceous (non-woody) plants. Mainstreaming biodiversity … When the disturbance was large, the quantitative values were the lowest, while the proportion of weeds was the highest. Grasslands cover around 40 percent of the earth's surface, and they exist in both temperate … Significant seasonal changes were recorded in community taxonomic groups, individual density, density-group indices, the Shannon and Pielou indices (P<0.01), and the significant change was also found with Simpson Index (P<0.05). from cultural grasslands. Grasslands are one of the major ecosystems of the world, covering close to one‐third of the Earth's terrestrial surface (Suttie et al. x��\˲ܶ�l�+�ˌKC/���8�r*�J\��UW�)[Ҍtu��gx�O�&?��@��9s�D�"� �F���޷��� �tq�z3tw����W��M��z�}q���+ۉ������v3��9�< :3�����>��z�������Hӻn�������.6߼����mXЧ_�������i��˕�v��=e��/���V!�b���V���Z�o���e�&������n��l߇����m���S��v������M? The research work was conducted in alpine meadow north of Qinghai Province in 1998. Along precipitation gradients grasslands are located between forests and deserts. Grassland Ecosystem : Essay on Grassland Ecosystem! The parent material is often composed of fine sediments, and grasslands are most often in valley or plateau landscapes. 1996 , White et al. Task sheet. In grasslands, the accumulation of organic matter is much more intensive. Grasslands are very diverse in terms of management, yield and biodiversity value. In contrast, both the above and belowground biomass were significantly decreased in the area that soil layer thickness is 3 - 5 cm only over burrows in which have been used continually in all season. Plant and animal Alpine meadows are extensively distributed in the northern Tibetan Plateau and are typical features of the region. It was concluded that the community' s characteristic values under low plateau pika disturbance intensity were high but the grazing quality was low, while high disturbance intensity resulted in the grassland degradation. The nature of grass litter and its pattern of decomposition commonly result in the development of a dark, organically rich upper soil layer that can reach 300 millimetres below the surface. ADVERTISEMENTS: The annual rainfall ranges between 25- 75 cm, usually seasonal. The grassland ecosystem occupies about 25% of the total land area throughout the world. Biome Notes 1. We examined the soil organic carbon content of natural alpine meadow, degraded meadow, artificial pasture and farmland, and estimated the potential of carbon sequestration of the latter three types based on former natural alpine meadow. In addition, the effects of temperature and precipitation on the soil meso- and microfauna community also implies increased global temperatures will have adverse short-term effects on soil fauna in the alpine meadow ecosystem. extend the pilot study on grassland ecosystem services which was elaborated in 2010. Within the grassland ecosystem are enormous numbers of very small organisms, including bacteria, fungi, algae, and viruses. They usually get more rain than grasslands. Introduction. The grasslands in North America are called prairies. It is found where rainfall is about 15-75 cm per year not enough to support a forest, but more than that of true desert. The relative abundance of herbivorous to omnivorous and/ or predatory nematodes obviously varied in different plant communities. A grassland ecosystem is the collection of plants, animals and micro-organisms that live within an environment where grasses are the primary form of vegetation. Over 1 million visitors annually enjoy the ecosystem services provided on the National Grasslands. ADVERTISEMENTS: The annual rainfall ranges between 25- 75 […] There are lots of similarities between improved grassland and enclosed farmland. stream This lesson introduces the concept of how populations, communities, and nonliving physical elements combine to create an ecosystem. A perfect review and reinforcement tool that is a one page worksheet consists of 12 open ended questions on grassland ecosystems. Grassland ecosystems in British Columbia generally occur in areas where the climate is hot and dry in summer and cool to cold and dry in winter. The last decade has seen much progress in our understanding of C 4 grass ecophysiology, C 4 grassland ecosystem ecology and geologic history, and the evolutionary history of the C 4 pathway within the grass lineage. Diverse types of animals can be found in forests, depending on their type. When the disturbance was small, the community had high quantitative values of coverage, aboveground biomass, biodiversity, and species richness, but the proportion of weeds was also high. Land-based ecosystems include forests and grasslands. Copy of The Prairie Grassland Ecosystem Copy of Apply Your Knowledge . iefly on the high central plateau of South Africa, and the inland area of KwaZulu-Natal and the Eastern Cape. They occur in regions too dry for forests and too moist for deserts. • Grasslands form a variety of different ecosystems located in different climatic conditions, ranging from near-desert conditions to patches of Shola Grasslands that occur on the hill-slopes along side the extremely moist evergreen forests in South India. C cycling and Net Biome Productivity in grasslands • Soil C and land management •CO2 fluxes • Farm gate budget and mitigation options • Upscaling to regional scale Conclusions. Among these are: • WATER The storage, cleansing and distribu-tion of available water resources are the most important services pro-vided by grasslands. A total of 33038 nematodes, which were classified to nematode phylum, 2 classes, 6 orders, 51 families and 93 genera, were collected during the surveys. It offers an up-to-date review of the recent advances in grassland research in China, discusses the climatic and physical conditions governing the grasslands, describes their types and distribution, and introduces a new classification scheme for grassland ecosystems. Providing hay and honey There are many ways for direct use of grassland products, which can be collected, Grasslands also support biodiversity and cultural services and are an important stock of carbon. Grassland ecosystem is a type of terrestrial ecosystem with an open land of grasses. Grassland ecosystems occur in areas of the world that have an annual precipitation between 150 and 1200 mm and mean annual temperature between 0 and 25 1C(Whittaker, 1975). Six 50 m × 50 m plots were established using permanent markers. The following soil chemical properties were tested: pH, potentiometry, soil water content (oven drying method), and electricity conductivity. 5 0 obj Grassland ecosystem study. Soil fauna play an important role in terrestrial ecosystems, directly or indirectly modulating the availability of resources for other species by changing biotic or abiotic materials. Grasslands have been playing a prominent role in biodiversity–ecosystem functioning research. Correlation of nutritional groups and environmental factors showed omnivorous/ predatory nematodes were affected significantly by water content during dry periods, while a close relationship was found between soil pH and fungivorous nematodes, which was obviously affected by electrical conductivity (EC) during periods of rapid growth. A grassland ecosystem is the collection of plants, animals and micro-organisms that live within an environment where grasses are the primary form of vegetation. But whatever above and belowground biomass greatly decreased in the overlying vegetation of burrows where plateau zokors colonized over 10 years in which the vegetation was obviously different with surrounding environment. 2011).Extensively managed grasslands are recognized globally for their high biodiversity (Habel et al. The results indicated the hypothesis that the excavation under ground by plateau zokor caused negative effect for the dicotyledons of taproots, but could promote the growth and development of the monocotyledons to some extent was correct. The nature of the ecosystem is based on its geo-graphical features such as hills, mountains, plains, rivers, lakes, coastal areas or islands. In natural grasslands, effects of warming on net ecosystem CO 2 exchange (NEE) may interact with grazing. Examples of grassland ecosystems include the prairies of western North America, the Pampas of Argentina and the Russian steppes. However, how the spatial variation of Rs and Q10 changes with abiotic and biotic factors across Chinese grasslands and their differences among grassland types still remain poorly understood. Altitude varies from near sea level to 2,850 m above sea level. Types of Grasslands. The landscape approach to conserving biodiversity in 18 working landscapes 3.2. INTRODUCTION Grasslands have historically been an area of expansion for human land use (White et al., 2001), and much of the world’s highly productive grassland has been converted to The answer is – there are 11 major grasslands in the world. Grasslands in Africa are called veldts and savannas--together, they cover almost half of the continent. Global Distribution of Grasslands and Grassland Soils. 6 major terrestrial (land) biomes – tundra, boreal forest, deciduous forest, tropical rainforest, grassland, desert 3. Grassland Ecosystem - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. In Europe and Asia, they are called steppes, and in South America, they are the pampas. Herbivorous and bacterivorous nematodes were the major nematode communities in the area. A typical alpine meadow in Zoigê County grassland located on the eastern edge of Qinghai-Tibet Plateau, China, was studied to document the composition, diversity, and seasonal variations of soil meso- and microfauna communities in alpine grasslands. The results showed that the above and belowground biomasses of dicotyledons were obviously decreased at first colonizing, and the biomasses of monocotyledons over burrows in which the excavated soil was backfilled was significantly increased in primary vegetation. The grassland ecosystem itself influences soil formation, and this causes grassland soils to differ from other soils. Grasslands occupy about 24% of the earth’s surface. PDF (7.61 MB) Enhance your ecosystem unit while providing an engaging learning experience for all of your various types of learners. Grazing is the main land use in natural and semi-natural grasslands and has a great impact on soil carbon pools (Derner et al., 2006; McSherry et al., 2013; Luo et al., 2015). Canada’s grasslands, this ecosystem supports an astonishing diversity of species; the African savanna, for example, is home to some of the world’s most iconic mammals, including giraffes, zebras, and lions. While the ecosystem was resistant to heat waves, it was not resistant to extreme drought, which reduced aboveground net primary productivity (ANPP) below the lowest level measured in this grassland in almost 30 years. The results showed that with the increase of the disturbance intensity, the dominant species changed from Juncus roemerianus to Poa pratensis and Laux maritima. The results were mostly within the scope of previous reports, and nematodes obviously appeared to aggregate in the upper soil layers. GRASSLAND ECOSYSTEMS EVS PPT 1. regulatory framework influencing the maintenance of grassland ecosystems in the Baltic States, evaluated existing experience in grassland management and studied best practice examples. Within the grassland ecosystem are enormous numbers of very small organisms, including bacteria, fungi, algae, and viruses. Land-based ecosystems include forests and grasslands. All Important grasslands around the world pdf > Remembering all the grasslands is common general knowledge for any competitive examinations like IAS, UPSC, SSC, CGL, Railway PSC, and Banking. Grassland Ecosystem: Grasslands occupy about 19% of the earth’s surface. The major grassland ecosystems of the world are the great plains of Canada and United States, S. Argentina to Brazil and S. Asia to Central Asia. The results showed that the four vegetation types have a great difference in potential of carbon storage of 0-40 cm soil layer: (1) the carbon storage in natural alpine meadow was the highest with 17098 g C/m 2, and were 5637, 3823 and 1567 g C/m 2for degraded meadow, artificial pasture and farmland, respectively; (2) soil organic carbon content and density in degraded meadow and artificial pasture were significant lower than those in natural meadow and farmland; (3) root carbon storage mainly concentrated in the 0-20 cm topsoil, and the natural alpine meadow was 3. It is Fig. Biome – has similar climate and plant and animal life. The research indicated soil nematode tropic composition varied from one plant community to another in alpine meadows. What Are Grassland Ecosystem Services Worth? The trophic composition, c-p group structure and functional structure index, as well as the characteristic values between trophic groups, c-p groups and soil properties, were analyzed to understand the effect of cold alpine conditions on soil nematode functional diversity. 3.1 CONCEPT OF AN ECOSYSTEM An ‘Ecosystem’ is a region with a specific and recognizable landscape form such as forest, grassland, desert, wetland or coastal area. The nature of grass litter and its pattern of decomposition commonly result in the development of a dark, organically rich upper soil layer that can reach 300 millimetres below the surface. That pilot study explained the choice of grasslands as a model ecosystem due to the importance which grasslands play in the European Union from the perspective of economy and EU budget as well as due to the long in tradition in agricultural management. Grasslands experience cooler dry season temperatures than savannas. In order to explore the impacts of plateau pika disturbance on the alpine grassland ecosystem and its grazing quality, the community characteristics under different disturbance intensities by plateau pika were analyzed, and a conceptual model about the alpine grassland community succession was proposed. Grassland ecosystems are present in every single continent on this planet with the sole exception of Antarctica, which is too cold to sustain a grassland ecosystem. Well, this is the most common question for an aspirant.
