“…In the bark of mature beech trees (Fagus sylvatica) growing on acidic soils in Southern Sweden, the range of N concentrations also was slightly higher (5.5-7.0 mg·g -1 D.M. ; [21]). In our investigation, the decrease in N concentration in the bark of the RD trees may have been caused by reduced N uptake as a consequence of decreased fine root production after defoliation -a reduction in fine-root biomass after defoliation of Q. robur has been found, e.g., by Block et al (1995) [7] and Gieger and Thomas (2002) [14].…”

-As a measure of frost hardiness, we determined an index of injury (I -30 ) in living bark tissue of 20-year-old pedunculate oaks (Quercus robur L.) that had been manually and almost completely defoliated in the first half of May of one or two years, and of non-defoliated control trees. I -30 was calculated as a percentage value on the basis of electrolyte leakage from samples artificially frozen at a temperature of -30°C, and from unfrozen control samples. In parallel, the bark's concentrations of soluble sugars, of nitrogen and of quercitol, a cyclic polyol, were measured. Repeated defoliation significantly reduced the frost hardiness of the bark as well as its concentrations of raffinose, stachyose, nitrogen and quercitol. The I -30 values were correlated with the total concentration of soluble sugars and with the concentrations of the individual sugar compounds, but not with the quercitol concentration. Less tight, yet significant correlations were obtained between I -30 and nitrogen concentrations. We conclude that repeated defoliation decreases the bark's capability to acclimatize to winter frost due to a reduction in the concentrations of soluble sugars, particularly those of raffinose and stachyose.

“…This result can be explained by weathering of the calcareous bedrock. High values were also found in other studies on a range of soils, with Ca concentrations in oak stem bark of about 30 to 50 times higher than in the sapwood of trees growing on podzol to dystrochrept soil (André andPonette 2003, Whittaker et al 1979), and about 20-30 mg g -1 on fertilized cambic podzols and dystric cambisols in Fagus sylvatica in southern Sweden (Jönsson 2000). In our study, Fagus sylvatica showed significantly higher Ca concentrations in the stem bark with increasing tree species diversity and increasing exchangeable Ca stocks in the soil.…”

Lorenzen et al. 2005a). The temperate forest experiment, BIOTREE, was planted in 2003 and is situated in Central Germany, Thuringia, close to the Hainich National Park. Response variables in this experiment also focus on productivity and biogeochemical cycles .Such experiments with artificially created gradients of even-aged and long-lived plants are important to detect underlying mechanisms of relationships between diversity and ecosystem processes, although they have shortcomings to transfer these results to multi-aged mature forest stands with its complex stand structure . Therefore, observational studies that compare diversity and ecosystem processes in different existing forest stands (e.g. Caspersen and Pacala 2001 are needed to complement manipulative experiments. Observational studies in mixed forests have the advantage to compare adult trees of stands with near-natural structure, intact food web structures and nutrient contents in biomass at a quasi steady state (Leuschner et al. 2009).previous study in this region found no significant effect of tree species richness on wood production, when environmental factors, such as climate, bedrock types, and radiation were included in the analysis . For temperate North American forests, Casperson and Pacala ( 2001) reported an asymptotic increase in wood production with increasing tree species richness. A study on productivity -diversity relations of forests worldwide failed to yield relationships between tree species number and production of above-ground tree biomass (Enquist and Niklas 2001). Our study will show further results on the biodiversityrichness relation in temperate forests.Foresters in European countries have conducted comparative studies mainly with pure and two-species stands on the effects of species mixtures on wood production for nearly a century (e.g. Cannell et al. 1992, Oltshoorn et al. 1999. Studies in temperate forests revealed that the productivity of mixed stands can decrease or increase by up to 30% compared to monospecies stands, depending on the specific physiology and growth potential of the species (Pretzsch 2005). Positive mixture effect with increasing productivity of one or two of the investigated tree species compared to the corresponding pure stands, so called overyielding, could be explained with complementarity in resource use (similar to results in grasslands) and decreased interspecific concurrence (e.g. Kennel 1965, Assmann 1970, Brown 1992, Morgan et al. 1992. No or negative effects of mixing species, due to competitive interactions where the inferior competitor can only be sustained by silvicultural interference are also for long known by foresters (e.g. Smith and Long 1992, Yanai 1992. Decomposition, nutrient release and mineralizationPlant species composition affects ecosystem nutrient cycling through plant-nutrient uptake and use, amount and chemical composition of the leaf litter, rhizosphere interactions and microenvironmental changes .Grassland experiments mainly focused on primary productivity, ecosystem nutrient...

“…It can be assumed that the requirements of N. ditissima for mineral and nitrogen nutrition that is provided to this fungus by longer annual shoots with greater growth can play an important role in this correlation. Similarly, Jönsson (2000) studied the soil treatment effects on bark lesions and frost sensitivity of beech in relation to the application of different treatments in beech stands (liming, wood ash, nitrogen). She reported that bark lesions on beech are mostly caused by frost damage and/or insect and fungal infections.…”

Symptoms of non-specific bark necroses in beech trees of all ages have lately been described. We investigated the occurrence of bark necrotic disease in beech thicket and health status of the trees. Our objective was to examine how bark necrotic wounds persist and the regenerative potential of young beech thicket. The research experiment was carried out at two isolated localities in the Western Carpathians in the period 2015–2017. A terminal shoot (stem) and a lateral shoot (branch) of each of the 30 sampled beech trees were examined. Young beech stands were affected by the necrotic disease in 87–94% cases (stems 69–83%, branches 33–56%). Shoot diameter and age had a significantly negative linear correlation (P < 0.05) with the development of all analysed disease characteristics on the beech bark. The encouraging finding is a positive regenerative capacity of young beech trees. Over the same period more annual shoots were healed in comparison with those that were newly infected (10.8% on stems and 0.6% on branches).
