“…The inverse relationship between soil pH and C/N ratio (Table 2) is coincident with previous studies of temperate forests (Härdtle et al 2005;Paal et al 2007;Naqinezhad et al 2008;Slezák & Petrášová 2010).…”

“…Zas & Alonso (2002) have shown that the species composition in forests is dependent more strongly on soil chemistry than on soil physical parameters. Conversely, the relevance of characteristics associated with soil texture was supported by ecological separation of alder-wood communities (Naqinezhad et al 2008). It should be noted that both soil chemical and physical properties can be often close correlated, either positively or negatively.…”

“…Biotic site-related factors, regional species-pool size and environmental variables are among the most frequently discussed drivers affecting the relative abundance and cover of understorey plant species (Dupré et al 2002;Svenning & Skov 2002;Leuschner & Lendzion 2009). While geographical and/or climatic gradients determine composition and structure of forest vegetation across large areas (Ellenberg 1982;Dzwonko & Loster 2000;Knollová & Chytrý 2004), soil chemical and physical properties along with moisture and light availability become more relevant at local scale (Härdtle et al 2005;Gálhidy et al 2006;Paal et al 2007;Naqinezhad et al 2008;Lalanne et al 2010;Slezák & Petrášová 2010).…”

Abstract:The deciduous forests represent dominant natural vegetation of Central European landscape and an important functional component for maintenance of biological diversity. However, their syntaxonomy and ecological gradients still remain unclear. The numerical classification was conducted to determine the main units of forest vegetation, while ordination techniques were used to explain the structure of vegetation-environmental data matrix consisting of 110 forest stands in the Štiavnické vrchy Mts (central Slovakia). Ten vegetation types within the phytosociological classes of deciduous forests Quercetea robori-petraeae and Querco-Fagetea were distinguished. The major environmental driver responsible for variation in forest species composition was interpreted as a response to soil moisture which also accounted for a large part of species variability (3.74%). Soil nutrient/acidity complex expressed by pH, Ca and Al concentration was also an important source of vegetation variability. Relevance of soil conditions in relation to plant survival and community distribution was discussed. Along the soil moisture gradient, vegetation types were arranged from the subxerophilous oak forests through the mesophilous beech and ravine forests to the hygrophilous alder ash vegetation.

“…8. Water chemistry is simplified to the pH range as it is sensitive to total mineralization, hardness and alkalinity and has been used in the classification of other ecosystems (Moore and Bellamy 1974;Wheeler and Proctor 2000;Tahvanainen 2004;Naqinezhad et al 2008). At the emergence scale, morphology and/or pedology are generally described, because they give information about the physical environments of GDEs, both on short and longterm scales and may also constrain nutrients availabilities.…”

Review: From multi-scale conceptualization to a classification system for inland groundwater-dependent ecosystems

Aquifers provide water, nutrients and energy with various patterns for many aquatic and terrestrial ecosystems. Groundwater-dependent ecosystems (GDEs) are increasingly recognized for their ecological and socio-economic values. The current knowledge of the processes governing the ecohydrological functioning of inland GDEs is reviewed, in order to assess the key drivers constraining their viability. These processes occur both at the watershed and emergence scale. Recharge patterns, geomorphology, internal geometry and geochemistry of aquifers control water availability and nutritive status of groundwater. The interface structure between the groundwater system and the biocenoses may modify the groundwater features by physicochemical or biological processes, for which biocenoses need to adapt. Four major types of aquifer-GDE interface have been described: springs, surface waters, peatlands and terrestrial ecosystems. The ecological roles of groundwater are conditioned by morphological characteristics for spring GDEs, by the hyporheic zone structure for surface waters, by the organic soil structure and volume for peatland GDEs, and by water-table fluctuation and surface floods in terrestrial GDEs. Based on these considerations, an ecohydrological classification system for GDEs is proposed and applied to Central and Western-Central Europe, as a basis for modeling approaches for GDEs and as a tool for groundwater and landscape management.

“…However, to support the socio-economic functions of the forest ecosystem, the conservation of stable and productive forests with diverse tree species must be ensured (Mölder et al, 2006;. The effects of environmental variables on plant communities have been the subject of many ecological studies in recent years (Pinto et al, 2006;Naqinezhad et al 2008;Ramirez et al, 2007;Mahmood and Athar, 2008;Lepetu et al, 2009;Kord et al, 2010). Effective and appropriate management of natural resources cannot be provided without a comprehensive scientific recognition.…”

Physiographic factors along with edaphic conditions play a crucial role in establishment of plant species throughout a region. Identification of the most effective factors is of high importance in sustainable management of a forest ecosystem. This study aims to investigate the relationships between understory vegetation and some environmental factors in natural forest ecosystems. This study has been carried out among the Fagetum orientalis communities of Ramsar Region, located in the north of Iran. For this purpose, 105 releves were sampled by a randomizedsystematic method throughout the study area, using the Braun-Blanquet scale. Physiographic parameters such as elevation, as well as slope and orientation were measured. By identification of the herb-layer vegetation contained in each sampling, vegetation composition and cover abundance of species were separately identified. Then, the aforementioned properties of soil were entirely measured in the taken samples. Cluster analysis and detrended correspondence analysis have been applied to classify the site. Moreover, in order to determine the relation between species composition and environmental factors, canonical correspondence analysis was used. Results showed a significant relation between distribution of plant types and environmental factors. Eventually, environmental factors including slope, orientation, silt percent, pH, organic matter and soluble phosphorous were among the most effective factors in establishment of Hedera pastuchowii, Solanum kieseritzkii, Oplismenus undulatifolius, Sedum stoloniferum, Rubus hyrcanus and Saxifraga cymbalaria species.
