Cím:River embankments mitigate the loss of grassland biodiversity in agricultural landscapes / Zoltán Bátori, Péter J. Kiss, Csaba Tölgyesi, Balázs Deák, Orsolya Valkó, Péter Török, László Erdős, Béla Tóthmérész, András Kelemen

Megjegyzések:Agricultural intensification has resulted in severe declines in the extent and diversity of seminatural habitats in Europe, whereas the extent of secondary habitats has increased considerably. River embankments have become one of the most extensive and widespread secondary habitats in former floodplains. We compared the diversity patterns of secondary dry and wet grasslands on river embankments with those of seminatural dry and wet grasslands in a Hungarian agricultural landscape using the following community descriptors: (a) species diversity, (b) phylogenetic diversity and (c) functional diversity. We also performed trait-based analyses to evaluate the ecosystem services provided by these secondary grasslands. Both grassland types of the embankments showed significantly higher Shannon diversity compared with their seminatural counterparts. The cover of generalist species (i.e., cosmopolitan species, weeds and nonindigenous plant species) was high in the secondary grasslands. We found significant differences in phylogenetic diversity between the secondary and seminatural grasslands: secondary grasslands showed significantly lower mean nearest taxon distances than the seminatural grasslands. Functional diversity did not differ between the secondary and seminatural grasslands according to the Rao's quadratic entropy. However, we found higher community-weighted means of specific leaf area, plant height and flowering period in the secondary grasslands, which are related to important ecosystem services (via biomass production and pollination). Well-planned management actions and restoration activities could help further improve the ecological function and conservation value of secondary grasslands on river embankments, contributing to the maintenance of species diversity and sustaining the functionality of ecosystems in agricultural landscapes.

Cím:Beyond the forest-grassland dichotomy : the gradient-like organization of habitats in forest-steppes / László Erdős, Péter Török, Katalin Szitár, Zoltán Bátori, Csaba Tölgyesi, Péter János Kiss, Ákos Bede-Fazekas, György Kröel-Dulay

Megjegyzések:Featuring a transitional zone between closed forests and treeless steppes, forest-steppes cover vast areas, and have outstanding conservation importance. The components of this mosaic ecosystem can conveniently be classified into two basic types, forests and grasslands. However, this dichotomic classification may not fit reality as habitat organization can be much more complex. In this study, our aim was to find out if the main habitat types can be grouped into two distinct habitat categories (which would support the dichotomic description), or a different paradigm better fits this complex ecosystem. We selected six main habitats of sandy forest-steppes, and, using 176 relevés, we compared their vegetation based on species composition (NMDS ordination, number of common species of the studied habitats), relative ecological indicator values (mean indicators for temperature, soil moisture, and light availability), and functional species groups (life-form categories, geoelement types, and phytosociological preference groups). According to the species composition, we found a well-defined gradient, with the following habitat order: large forest patches, medium forest patches, small forest patches, north-facing edges, south-facing edges, and grasslands. A considerable number of species were shared among all habitats, while the number of species restricted to certain habitat types was also numerous, especially for north-facing edges. The total (i.e., pooled) number of species peaked near the middle of the gradient, in north-facing edges. The relative ecological indicator values and functional species groups showed mostly gradual changes from the large forest patches to the grasslands. Our results indicate that the widely used dichotomic categorization of forest-steppe habitats into forest and grassland patches is too simplistic, potentially resulting in a considerable loss of information. We suggest that forest-steppe vegetation better fits the gradient-based paradigm of landscape structure, which is able to reflect continuous variations.
