![]() Regarding 15N, PS gave a more congruent picture with the location of the main sources of N emissions in the area.Īll these data suggested that PS may be a suitable biomonitor in Mediterranean areas.īesides, bryophytes are among the most vulnerable organisms to N pollution. HC), a commonly used and validated species in biomonitoring surveys.īoth bryophytes showed similar spatial distribution patterns for N. To that end we compared the response of this species to that of Hypnum cupressiforme Hedw. PS) as an alternative species for heavy metals and N deposition surveys in a Mediterranean area of southern Europe. In the other chapters we studied N atmospheric pollution by using mosses as biomonitors.įirstly, we evaluated the feasibility of Pleurochaete squarrosa (Brid.) Lindb. The results showed that the contribution of the organic fraction to the total N budgets ranged in BD from 34 to 56, and in TF from 38 to 72.ĭata also revealed that agricultural activities and traffic-related pollutants generated in metropolitan areas may play an important role as potential sources of organic nitrogenous compounds.įinally, it was found that DON might be an additional nutrient for this forests type (canopy uptake). Pearson Cutting Edsge Series Diagnostic Drivers Of Theīoth canopy throughfall and bulk deposition samples from four holm oak forests of the Iberian Peninsula were analyzed for their dissolved organic nitrogen (DON) content.Detailed, user-friendly contents maps help you plan lessons quickly.Make full use of the course package with clearer sign posting and cross-referencing to other components.Can Do statements helps you plan lessons more effectively.
