Arbuscular mycorrhizal (AM) fungi form symbiotic associations with most plant species in terrestrial ecosystems, and are affected by environmental variations. To reveal the impact of disturbance on an AM fungal community under future global warming, we examined the abundance and community composition of AM fungi in both soil and mixed roots in an alpine meadow on the Qinghai-Tibetan Plateau, Ch...

floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. unique ecological and climatic conditions in the northernkhorasan province (nkp) make it a remarkable habitat for the floristic studies. plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.surveys were conducted during active growth per...

Root litter is the dominant soil carbon and nutrient input in many ecosystems, yet few studies have considered how root decomposition is regulated at the landscape scale and how this is mediated by land-use management practices. Large herbivores can potentially influence below-ground decomposition through changes in soil microclimate (temperature and moisture) and changes in plant species compo...

The impacts of agro-pastoral activities on soil properties, plus nutritive value and residual standing biomass herbaceous plants in areas different land uses western Serengeti, were evaluated. Vegetation sampled along 4,000 m transects laid across fallow land, grazed only by livestock, mixed grazing (livestock wildlife) wildlife only. A total number 123 plant species encountered during sampling...

BACKGROUND Livestock grazing is the most prevalent land use of grasslands worldwide. The effects of grazing on plant C, N, P contents and stoichiometry across hierarchical levels, however, have rarely been studied; particularly whether the effects are mediated by resource availability and the underpinning mechanisms remain largely unclear. METHODOLOGY/PRINCIPAL FINDINGS Using a multi-organiza...

Reintroduction of fire and grazing, alone or in combination, has increasingly been recognized as central to the restoration of North American mixed-grass and tallgrass prairies. Although ecological studies of these systems are abundant, they have generally been observational, or if experimental, have focused on plant species diversity. Species diversity measures alone are not sufficient to info...

introduction climate change is one of the most important challenges in sustainable development, which has a negative impact on aquatic and terrestrial ecosystems. this will change rainfall patterns the power to increase hurricane and the risk of drought, flood and will strengthen pressure on water resources. researchers generally agree that the main cause of the increase in global temperature i...

sion illustrates the difficulty that current researchers face in obtaining consensus from this generality. More than a century since Charles Darwin stated that diverse Species diversity is a hot topic in grassland ecology regrasslands produce more herbage than monocultures, scientists still search because the reported benefits of biodiversity apdebate the relationship between species diversity ...

Grazing by large herbivores is well-known to influence plant communities, while much fewer studies have been carried out on grazing effects on invertebrates. In Norway, some 2.2 million sheep graze on outlying pastures during summer, most of them in the alpine zone, but no study has reported the relative impact of sheep grazing on invertebrate communities relative to other environmental factors...
