“…High Mn levels may lead to plant nutrient imbalances (Paschke et al 2005), especially in relation to some divalent cations, such as Mg 2+ and Ca 2+ (Marschner 1995;Cenni et al 1998). One of the first symptoms as a result of Mn toxicity is related to Mg deficiency (Marschner 1995).…”

Manganese (Mn) uptake capacities of water hyacinth (Eichhornia crassipes (Mart.) Solms, water lettuce (Pistia stratiotes L.) and slligator alternenthera (Alternanthera philoxeroides) were investigated with four Mn levels: 0(control), 50, 200, 400 mg/L. With increased Mn exposure, the tested plants showed similar responses with a decrease in relative growth rate and an increase in plant Mn concentrations. Comparatively, water lettuce had the significantly higher total Mn concentrations, shoots enrichment factor and translocation factor at all Mn‐treated treatments and the much greater total Mn removal at concentrations of 200 and 400 mg/L Mn. In most cases, Mn pollution significantly decreased Mg concentrations for all three plants. Concomitantly, increment trends of Fe, Cu and Zn concentrations were observed for water lettuce with the increasing external Mn concentrations, which could partly contribute to its higher Mn concentrations. The results indicated that water lettuce have standout potentials as a phytoremediation plant for Mn contaminated waters.

“…Pinus nigra has the highest ratio between dead and extremely defoliated trees, indicating mortality not connected to defoliation. This behaviour may be connected to the ageing and decline of past afforestation programmes [63]. Alpine conifers (P. abies and L. decidua) have low defoliation levels (Def > 25%).…”

Forest health and multifunctionality are threatened by global challenges such as climate change. Forest health is currently assessed within the pan-European ICP Forests (International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests) programme through the evaluation of tree crown conditions (defoliation). This paper analyses the results of a 24-year assessment carried out in Italy on 253 permanent plots distributed across the whole forested area. The results evidenced a substantial stability of crown conditions at the national level, according to the usual defoliation thresholds Defoliation > 25% and Defoliation > 60%, albeit with species-specific patterns. Within this apparent temporal stability, an increased fraction of extremely defoliated and dead trees was observed. Extreme defoliation mostly occurred in years with severe summer drought, whereas mortality was higher in the years after the drought. The results for singular species evidenced critical conditions for Castanea sativa Mill. and Pinus species, whereas Quercus species showed a progressive decrease in defoliation. Deciduous species, such as Fagus sylvatica L., Ostrya carpinifolia Scop. and Quercus pubescens Willd. suffer the loss of leaves in dry years as a strategy to limit water loss by transpiration but recover their crown in the following years. The recurrence of extreme heat waves and drought from the beginning of the XXI century may increase the vulnerability of forests, and increased tree mortality can be expected in the future.
