“…The most significant reduction in long‐distance migrants can be expected if winter temperature increases, spring temperature decreases, and spring precipitation increases ( Table 2), ( i.e., if climate conditions become less continental ). Changes to less continental climate conditions have already been recorded for some regions in Europe ( Vygodskaya et al 1995 ).…”

Little evidence exists demonstrating that global climate change leads to systematic changes in the structure of ecological communities. For avian communities, one would expect warmer winters to lead to declines in numbers of long‐distance migrants if resident birds benefit from warmer winters and impose increasing competitive pressure on migrants. To study the potential influence of global climate change on long‐distance migrants, we correlated the number of all species of land birds and the number and proportion of long‐distance migrants, short‐distance migrants, and residents in 595 grid cells across Europe. We used mean temperature of the coldest month, mean spring temperature, and spring precipitation as measures of climatic conditions in winter and during the breeding period. The number and proportion of long‐distance migrants decreased with increasing winter temperature, decreasing spring temperature, and increasing spring precipitation. We used this spatial relationship between bird community structure and climate in Europe to make predictions about changes in bird communities of the Lake Constance region, Central Europe, between two census periods ( 1980–1981 and 1990–1992 ). Winter temperature in this region increased significantly between the two censuses, whereas spring temperature and precipitation did not change. As predicted from the models, the proportion of long‐distance migrants decreased and the number and proportion of short‐distance migrants and residents increased between the two censuses. The significant declines of the long‐distance migrants in the Lake Constance region are of a magnitude that can be explained by the observed climate change. Our results suggest that increasingly warmer winters may pose a more severe threat to long‐distance migrants than to the other bird groups.

“…Both the lack of difference in the acid-extractable Ca concentrations between sites and the absence of negative correlation with organic matter support this hypothesis. In theoretical ecosystem models based on material balance (Ulrich 1992) podzolisation and accumulation of organic matter in the O horizon are processes leading to ecosystem decline. Supporting this, in empirical investigations Wardle et al (1997Wardle et al ( , 2004, could show that accumulation of organic matter is related to stagnation of ecosystem processes and ecosystem decline.…”

“…Different species of trees affect the amounts and the quality of soil organic matter, and influence fertility properties such as pH, cation exchange capacity and the equilibrium between pools of nutrients (Binkley and Giardina 1998;van Breemen and Finzi 1998). However, much of the information about tree species effects on soil properties is from mono-specific stands or comparison with mono-specific stands (Thelin et al 2002).…”

Soil properties under Norway spruce differ in spruce dominated and mixed broadleaf forests of the Southern Taiga

et al. 2008

In natural forest, disturbance changes tree species composition which in turn affects soil properties. Two areas in the Central Forest State Biosphere Reserve, in the Russian Southern Taiga Zone, differed in the intensity of disturbance: Norway spruce was the dominant species at one site, while at the other spruce was mixed with broadleaves. The presence of broadleaves was due to large gaps in the canopy having been formed, which have triggered vegetation succession. At both sites, five plots were selected to evaluate how the presence of broadleaves influences the properties of the soils under spruce. Soil samples were taken close to spruce trees and the O, A and E horizons were analysed. A difference in the distribution of organic matter in the soil horizons was evident, with a higher concentration in the O and A horizons at the spruce dominated site, while a more homogeneous distribution was found under spruce at the site where broadleaves were abundant. The organic matter did not only differ in quantity, but also in quality as estimated by the C/N ratio, and therefore affected the CEC and element relative availability. No differences at the two sites were found for water-extractable and exchangeable elements, but the ratio between the exchangeable and the acidextractable forms were different, suggesting a higher relative availability of the elements at the spruce dominated site, and thus potentially higher leaching. Both theoretical and empirical studies have suggested that podzolisation and accumulation of organic matter in the O horizon are related to stagnation of ecosystem processes and ecosystem decline. Our data suggest that the presence to windthrow sites and the inclusion of broadleaf species acts to slow or even reverse podzolisation even in spruce dominated sites.

“…The area is a watershed with a weakly cut relief, the topography ranges from flat to gently undulating. The vegetation is that of a typical southern boreal forest (Vygodskaya et al 1995), where the main vegetation disturbance takes the form of windthrow, favouring the entrance of broadleaves in an ecosystem otherwise dominated by conifers (Drobyshev 2001). No wild fires have been reported in the CFSBR for at least 100 years (Ulanova 2000).…”

Fine root biomass and turnover in southern taiga estimated by root inclusion nets

Fine roots play an important part in forest carbon, nutrient and water cycles. The turnover of fine roots constitutes a major carbon input to soils. Estimation of fine root turnover is difficult, labour intensive and is often compounded by artefacts created by soil disturbance. In this work, an alternative approach of using inclusion nets installed in an undisturbed soil profile was used to measure fine root production and was compared to the in-growth core method. There was no difference between fine root production estimated by the two methods in three southern taiga sites with contrasting soil conditions and tree species compositions in the Central Forest State Biosphere Reserve, Russia. Expressed as annual production over standing biomass, Norway spruce fine root turnover was in the region of 0.10 to 0.24 y -1 . The inclusion net technique is suitable for field based assessment of fine root production. There are several advantages over the in-growth core method, due to non-disturbance of the soil profile and its potential for very high rate of replication.
