These slopes are covered with a vegetation mosaic of different steppe Communities and small, savanna-like, U. pumila open woodlands. The hypothesis is tested that the xeric microclimate and high herbivore densities limit the success of seedling establishment in U. pumila and thereby prevent elm from complete encroachment of the grassland-dominated slopes. Seeds were sown and 2-yr-old seedlings were planted prior to the growing season. The water Supply was manipulated by irrigation, as was the feeding pressure by caterpillars with an insecticide. Large herbivores were excluded by fencing. Seeds germinated throughout the summer, but the emerged seedlings did not survive for more than 2 or 3 weeks. Germination rates increased with increasing soil water content and decreasing soil temperatures. Many seeds were consumed by granivores. Most planted 2-yr-old seedlings survived the two growing seasons covered by the study. However, the seedlings suffered from feeding damage by insects (gypsy moth, grasshoppers) and small mammals, from nitrogen deficiency and, to a lesser degree, from drought. The results suggest that high susceptibility of newly emerged seedlings to environmental stresses is a serious bottle neck for U. pumila that prevents them from the formation of closed forests on northern Mongolia's steppe slopes, whereas the probability for seedling survival after this early stage is high.

These stands limited to the middle and lower parts of the slopes consist of single trees or small groups of trees of up to 5 m height. Parts of the tree crowns are characteristically dead. The stands have a marked shrub layer of, e.g.. small individuals of U. pumila as well as Spiraea aquilegifolia, Padus asiatica, and Ribes diacantha, and a diverse, but patchy ground vegetation. U. pumila is limited to loose, deep, stony soils on the slopes, which preferably occur near rock outcrops, mostly in contact to mountain steppe. Fine-grained, non-skeletal soils are avoided by U. pumila, but inhabited by meadow steppe. The preference for stony soils is attributable to the high water requirements of U. pumila. as rock cracks are known to form a reservoir for rain and dew water. The high demand for water is a partly a consequence of a low VPD sensitivity of the stomata regulation known for U. pumila. High transpiration rates may help U. pumila to avoid elevated leaf temperatures under high solar irradiation on the exposed steppe slopes. Increasing non-photochemical quenching at a PPFD > 2000 mu mol m(-2) s(-1) gives additional evidence of the good adaptation of U. pumila to sunlit environments. Minimum shoot water potentials far above the point of zero turgor throughout the growing season suggest sufficient water supply in summer in years with average rainfall. Literature data indicate that U. pumila can also suffer lethal damage on the rocky slopes during exceptionally dry summers. Insect herbivory was of subordinate significance for the elm trees. Therefore, desiccation is thought to be the main cause of the frequent occurrence of dead crown parts and the early death of the elm trees on the sun-exposed slopes. Mean age of the sample trees was as low as 17 years. At this age, the trees are not fertile, but proliferate vegetatively. The low lifespan of U. pumila on the sun-exposed slopes suggests that these slopes are a suboptimal habitat for this tree species. The dependence on loose, stony soils alone explains the irregular distribution of U. pumila on the sun-exposed slopes and rules out the formation of closed elm forest at these sites.

Here, we present a dendrochronological analysis in three mixed temperate broad-leaved forests along a precipitation gradient with the aim of comparing the climatic response of radial growth of F. sylvatica with the performance of four co-existing species (Acer pseudoplatanus, A. platanoides, Quercus petraea, Fraxinus excelsior). We hypothesized that Fagus is the most drought sensitive of the five species, which implies that it could lose its competitive advantage at drier sites in the course of climate warming. In support of this hypothesis, we found that F. sylvatica in all stands exhibited an increase in the number of negative pointer years and a decrease in radial increment in the driest stand since about 1980, in parallel to increasing summer temperatures and drought intensity. Such a response was missing in the other four species and may point to shifts in the competitive hierarchy in these mixed forests under a future warmer climate.

A major aim of the study was to assess whether reduced productivity by gypsy moth herbivory could contribute to fluctuations of the forest edge to the steppe in larch-dominated woodlands. In the year of the infestation, larch trees at the forest edge lost 90% of their needles and latewood formation was strongly reduced. However, earlywood formation was widely completed before the gypsy moth attack and, therefore, total tree-ring width was not below the average of the five years prior to infestation. In the two years following the gypsy moth invasion, annual stem increment was strongly reduced. Trees growing 30-100 m inside the forest showed a much weaker response of tree-ring widths to the gypsy moth infestation consistent with significantly higher defoliation at forest edge than in the forest interior. Old trees exhibited a stronger growth decline than middle-aged trees, indicating higher infestation of dominant, exposed trees, which are thought to be better accessible to the wind-dispersed gypsy moth larvae hatching in the early growing season on the steppe. Under the current climate, occasional growth reductions are thought to be of little effect on the performance of L. sibirica, as fast-growing competitors of other tree species, which are not or hardly affected by gypsy moth, are absent.

We compared tree-ring chronologies and the climate sensitivity of growth (MS) in 11 mature beech stands along a precipitation gradient (855–576 mm y−1) on two soil types with contrasting water storage capacity (WSC) in northwest Germany to test the hypotheses that recent warming is impairing beech growth also in the center of its distribution below a certain precipitation limit, and stands with low soil WSC are more susceptible.

The frequency of negative pointer years and MS were highest in low-precipitation stands on sandy soil, but both parameters have increased during the last decades also in the moister stands.

Forests in this region (at ca. 2300 m a.s.l.) are highly fragmented and border on steppe and alpine grasslands, which are used for mobile livestock husbandry. The climate in Central Asia is warming to levels clearly above the global average, which affects the vegetation. Furthermore, the transition from planned to market economy and the decollectivization of livestock 20 years ago has strongly changed land use practices in Mongolia, especially resulting in an increase in recent logging activities. We were interested in the question how climate warming and selective logging influence the annual stem growth and the stand structure.Methods The impact of climate and land use by the pastoral nomads on the annual stem increment of more than 1800 trees of Siberian larch (Larix sibirica) was analyzed. Different groups of trees with divergent growth trends depending on the social position and stand history were identified by non-metric multidimensional scaling and analysis of similarities. Long-term trends in the annual stem increment were analyzed by establishing separate regional growth curves for trees of different age classes.Important FindingsInstrumental climate data substantiate an increase of temperature by 2.1°C since 1940 at constant precipitation. Trees benefit from the increased temperatures. Climate-response analysis revealed that radial stem increment was promoted by the temperature in early summer, but also high precipitation in spring and in the year before tree-ring formation. Forest dynamics is also strongly influenced by anthropogenic activities. In addition to the natural forest dynamics, logging resulted in divergent growth trends within given age classes and habitats (forest interior and forest edge); overall, 22 groups of trees with different characteristics in the annual radial stem increment were identified. A tree-ring series-based reconstruction of logging intensity since 1935 suggests that moderate selective logging occurred throughout the study period. However, selective logging was strongly intensified after 1990 as the result of the breakdown of the Communist regime in Mongolia and the transition from centrally planned to market economy. Because tree stump densities showed that the ratio of felled to live trees was 2:1 in the interior or even 0.9:1 at the edges of the forests and most logging occurred during the past 20 years, it must be concluded that the forests of the Mongolian Altai are presently exploited far beyond the level of sustainability. A close correlation of the ratio of felled to live trees with the density of summer camps of pastoral nomads in the vicinity suggests that trees are primarily felled by the local population."],["dc.identifier.doi","10.1093/jpe/rtt019"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15231"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Response of tree-ring width to climate warming and selective logging in larch forests of the Mongolian Altai"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
