| 1 | Selective uptake of major and trace elements in Erica andevalensis,an endemic species to extreme habitats in the Iberian Pyrite Belt显示文摘To assess the ecophysiological traits and the phytoremediation potential of the endemic heather Erica andevalensis,we determined the concentrations of major and trace elements in different plant parts and in rizosphere soils from Riotinto mining district (Huelva,Spain).The results showed that E.andevalensis may grow on substrates with very high As,Cu,Fe and Pb concentrations (up to 4114,1050,71900 and 15614 μg/g dry weight,respectively),very low availability of macro-and micronutrients and with pH values ranging from 3.3 to 4.9.In these harsh edaphic conditions E.andevalensis selectively absorbed and translocated essential nutrients and excludes potentially phytotoxic elements,which were accumulated in the root epidermis.The concentrations of major and trace elements in E.andevalensis aerial parts from the Riotinto mining district were in the normal range for plants;likewise other Erica species it accumulated Mn and only in a very polluted site we measured leaf concentrations of As and Pb within the excessive or toxic limits for plants.Differently from previous studies,which emphasized the soil pH and bioavailability of phytotoxic elements as the main stress factors,this study showed that in the Riotinto region,E.andevalensis can tolerate wide range of pH and toxic element concentrations;the harshest environments colonized by monospecific patches of this species were characterized above all by very low availability of nutrients.The extraordinary capability to adapt to these extreme habitats made E.andevalensis a priority species to promote the phytostabilization and the development of a self-sustaining vegetative cover on Riotinto mine tailings. | Fabrizio Monaci Eduardo O.Leidi Maria Dolores Mingorance Benito Valdés Sabina Rossini Oliva Roberto Bargagli | 2011 | Journal of Environmental Sciences2011，23，3： | 2 |
| 2 | Persistent pollutants and the patchiness of urban green areas as drivers of genetic richness in the epiphytic moss Leptodon smithii显示文摘We determined genetic variation and metal and polycyclic aromatic hydrocarbon concentrations in Leptodon smithii moss collected in holm oak stands at cities,outskirts and remote areas of Campania and Tuscany(Italy)to investigate if anthropogenic pressure(pollutant emissions and land use change)affects moss genetic richness.In both regions,metal and polycyclic aromatic hydrocarbon concentrations reflected the trend urban>outskirts>remote areas,excepting Tuscany remote site.In both regions,the moss gene diversity increased from urban to remote areas.The findings suggest the extent and the fragmentation of urban green areas,as drivers of moss genetic richness. | Valeria Spagnuolo Flavia De Nicola Stefano Terracciano Roberto Bargagli Daniela Baldantoni Fabrizio Monaci Anna Alfani Simonetta Giordano | 2014 | Journal of Environmental Sciences2014，26，12： | 0 |
