Soil Fungal Community in Grazed Inner Mongolian Grassland Adjacent to Coal-Mining Activity.
2021
Coal mining results in reduced soil quality and makes environments less stable. Soil fungi are suitable indicators of soil quality for monitoring purposes. Here, the objective was therefore to investigate the effects of grazing and mining on the composition of the soil fungal community at the periphery of an opencast coal-mine dump in the Shengli mining area, Xilingol League, Inner Mongolia. A total of 2110 fungal operational taxonomic units (OTUs) were identified and subdivided into 81 orders and nine categories, based on trophic modes. The sensitivity of soil factors to coal-mining and grazing was differently. The sensitive factor to mining was soil pH, and that to grazing were soil nitra…
Phylogeographical structure in the coastal speciesSenecio rodriguezii(Asteraceae), a narrowly distributed endemic Mediterranean plant
2009
Aim Our goals were (1) to assess the levels of chloroplast DNA variation in a narrowly distributed plant restricted to continental islands, (2) to ascertain whether a phylogeographical structure is present in plants restricted to coastal linear systems, and (3) to interpret the results in the light of the known palaeogeography of these islands. Location The Eastern Balearic Islands (Majorca and Minorca) in the Western Mediterranean Basin. Methods Sampling included 134 individuals from 28 populations of Senecio rodriguezii covering the entire range of the species. Sequences of the chloroplast genome (trnT-trnL spacer) were obtained and parameters of population genetic diversity and substruct…
