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:River Dikes in Agricultural Landscapes : The Importance of Secondary Habitats in Maintaining Landscape-Scale Diversity / Zoltán Bátori, László Körmöczi, Márta Zalatnai, László Erdős, Péter Ódor, Csaba Tölgyesi, Katalin Margóczi, Attila Torma, Róbert Gallé, Viktória Cseh, Péter Török

Megjegyzések:Lowland rivers and their floodplains have changed markedly over the last centuries. River dikes have become among the most extensive secondary habitats of former floodplains. Our main question was, what role do secondary habitats on river dikes play in harbouring plant species and maintaining plant diversity of lowland landscapes dominated by agricultural areas? We compared historical maps and current habitat maps to understand the effects of landscape changes on the vegetation pattern of the study region, in southern Hungary. Dikes and primary vegetation of the landscape were selected for intensive vegetation sampling. We compared the floristic similarity and the Shannon diversity of the vegetation types. We used ordinations to visualize relationships among the vegetation types and among dike vegetation and environmental variables. Our results indicated that profound changes have been brought about in the vegetation during the last 150 years, resulting in a transition from marshland to agricultural land. The species composition and pattern of dike vegetation strongly depended on their relative position to the river and their aspect. We conclude that dikes can harbour many vascular plants that are absent or rare in the surrounding habitats and therefore play a decisive role in maintaining plant diversity in agricultural landscapes.

Cím:Species-based indicators to assess habitat degradation: Comparing the conceptual, methodological, and ecological relationships between hemeroby and naturalness values / László Erdős, Ákos Bede-Fazekas, Zoltán Bátori, Christian Berg, György Kröel-Dulay, Martin Magnes, Philipp Sengl, Csaba Tölgyesi, Péter Török, Jack Zinnen

Megjegyzések:Naturalness and hemeroby indicator values are specialized species-based indicators used in Continental Europe that reflect plant species' affinity to degraded habitats. Despite their potential utility for basic and applied science, their similarities have gone unnoticed, and they have yet to be studied together. Here, we combine literature review and novel data analyses to ask 1) How are the naturalness and hemeroby indicator systems related, and 2) Do naturalness and hemeroby indicator values reflect similar functional patterns? To address these questions, we first reviewed the conceptual and methodological differences underlying naturalness and hemeroby values. We then directly compared the indicator values, including splitting species by origin. Next, to determine if the values capture similar ecological patterns, we related the indicator values to leaf traits, specifically leaf area, dry matter content, and specific leaf area. The main conceptual difference we identified was the differing reference states of the systems: naturalness values are value-laden and emphasize a lack of human influence, whereas hemeroby values are evaluative and apply the potential natural vegetation concept. Naturalness and hemeroby indicators have contrasting resolutions on opposite ends of the naturalness/degradation continuum, with naturalness placing greater emphasis on lightly impacted areas, whereas hemeroby divides degraded contexts more finely. Overall, naturalness and hemeroby values were inversely related. Naturalness and hemeroby values were strongly (rho < -0.6) correlated in direct comparisons. These correlations were curvilinear due to the scoring differences for non-native species: the systems had contrasting score variances (i.e., resolution) between non-native and native species. Leaf traits were generally "mirror images" between the systems; hemeroby was negatively associated with dry matter content and positively associated with specific leaf area, and vice versa for naturalness.. However, these relationships were weak (R-2 < 0.05). The weakness of these patterns implies that species' degradation tolerance may not be generalizable by simple leaf traits. Our work showed that hemeroby and naturalness are inverse, bilaterally consistent indicator systems. These indicator values, or improved versions of them, could be better utilized in the future for applied management and conservation.

Cím:How climate, topography, soils, herbivores, and fire control forest-grassland coexistence in the Eurasian forest-steppe / László Erdős, Péter Török, Joseph W. Veldman, Zoltán Bátori, Ákos Bede-Fazekas, Martin Magnes, György Kröel-Dulay, Csaba Tölgyesi
Dátum:2022
ISSN:1464-7931 1469-185X
Megjegyzések:Recent advances in ecology and biogeography demonstrate the importance of fire and large herbivores - and challenge the primacy of climate - to our understanding of the distribution, stability, and antiquity of forests and grasslands. Among grassland ecologists, particularly those working in savannas of the seasonally dry tropics, an emerging fire-herbivore paradigm is generally accepted to explain grass dominance in climates and on soils that would otherwise permit development of closed-canopy forests. By contrast, adherents of the climate-soil paradigm, particularly foresters working in the humid tropics or temperate latitudes, tend to view fire and herbivores as disturbances, often human-caused, which damage forests and reset succession. Towards integration of these two paradigms, we developed a series of conceptual models to explain the existence of an extensive temperate forest-grassland mosaic that occurs within a 4.7 million km(2) belt spanning from central Europe through eastern Asia. The Eurasian forest-steppe is reminiscent of many regions globally where forests and grasslands occur side-by-side with stark boundaries. Our conceptual models illustrate that if mean climate was the only factor, forests should dominate in humid continental regions and grasslands should prevail in semi-arid regions, but that extensive mosaics would not occur. By contrast, conceptual models that also integrate climate variability, soils, topography, herbivores, and fire depict how these factors collectively expand suitable conditions for forests and grasslands, such that grasslands may occur in more humid regions and forests in more arid regions than predicted by mean climate alone. Furthermore, boundaries between forests and grasslands are reinforced by vegetation-fire, vegetation-herbivore, and vegetation-microclimate feedbacks, which limit tree establishment in grasslands and promote tree survival in forests. Such feedbacks suggest that forests and grasslands of the Eurasian forest-steppe are governed by ecological dynamics that are similar to those hypothesised to maintain boundaries between tropical forests and savannas. Unfortunately, the grasslands of the Eurasian forest-steppe are sometimes misinterpreted as deforested or otherwise degraded vegetation. In fact, the grasslands of this region provide valuable ecosystem services, support a high diversity of plants and animals, and offer critical habitat for endangered large herbivores. We suggest that a better understanding of the fundamental ecological controls that permit forest-grassland coexistence could help us prioritise conservation and restoration of the Eurasian forest-steppe for biodiversity, climate adaptation, and pastoral livelihoods. Currently, these goals are being undermined by tree-planting campaigns that view the open grasslands as opportunities for afforestation. Improved understanding of the interactive roles of climate variability, soils, topography, fire, and herbivores will help scientists and policymakers recognise the antiquity of the grasslands of the Eurasian forest-steppe.

Cím:The distribution of Ranunculus psilostachys Griseb. in Hungary and the question of its indigenousness / László Erdős, Balázs Kevey, Péter Török, Csaba Tölgyesi, Norbert Bauer
Dátum:2022
ISSN:1210-0420
Megjegyzések:Ranunculus psilostachys is native to the Balkan Peninsula and in Hungary it is currently known from the Villány Mountains and the Nyárád-Harkány Plain. Its origin in Hungary (native vs. introduced) has been debated since it was first discovered in the country. In this paper we provide an overview of the distribution of the species in Europe and Hungary, then we classify its Hungarian occurrences into six categories based on their naturalness level. We think that R. psilostachys may be native in its natural and seminatural habitats but because of its impressive appearance it is presumably planted in some secondary habitats, including sacred sites. We assume that these occurrences are not independent from one another, i.e., local people used native populations as a source of the species used as an ornamental plant.

Megjegyzések:Despite the ecological, economic and conservation importance of forest-steppes, a continental scale synthesis of this complex ecosystem has been lacking. In a recent review, we compiled scattered knowledge about Eurasian forest-steppes in a new synthesis, proposed a new forest-steppe definition, reviewed how the biogeographic position of this ecosystem is perceived by different authors from different regions, delineated the main regions based on criteria of flora, physiognomy (i.e., vegetation structure), relief, and climate, and explored the conservation importance of forest-steppes. Here we complement some of the key findings of the review and illustrate some topics with further specific examples.

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.

Megjegyzések:Aims: Eurasian forest-steppes are among the most complex non-tropical terrestrial ecosystems. Despite their considerable scientific, ecological and economic importance, knowledge of forest-steppes is limited, particularly at the continental scale. Here we provide an overview of Eurasian forest-steppes across the entire zone: (a) we propose an up-to-date definition of forest-steppes, (b) give a short physiogeographic outline, (c) delineate and briefly characterize the main forest-steppe regions, (d) explore forest-steppe biodiversity and conservation status, and (e) outline foreststeppe prospects under predicted climate change. Location: Eurasia (29°-56°N, 16°-139°E). Results and Conclusions: Forest-steppes are natural or near-natural vegetation complexes of arboreal and herbaceous components (typically distributed in a mosaic pattern) in the temperate zone, where the co-existence of forest and grassland is enabled primarily by the semi-humid to semi-arid climate, complemented by complex interactions of biotic and abiotic factors operating at multiple scales. This new definition includes lowland forest?grassland macromosaics (e.g. in Eastern Europe), exposurerelated mountain forest-steppes (e.g. in Inner Asia), fine-scale forest?grassland mosaics (e.g. in the Carpathian Basin) and open woodlands (e.g. in the Middle East). Using criteria of flora, physiognomy, relief and climate, nine main forest-steppe regions are identified and characterized. Forest-steppes are not simple two-phase systems, as they show a high level of habitat diversity, with forest and grassland patches of varying types and sizes, connected by a network of differently oriented edges. Species diversity and functional diversity may also be exceptionally high in foreststeppes. Regarding conservation, we conclude that major knowledge gaps exist in determining priorities at the continental, regional, national and local levels, and in identifying clear target states and optimal management strategies. When combined with other threats, climate change may be particularly dangerous to forest-steppe survival, possibly resulting in compositional changes, rearrangement of the landscape mosaic or even the latitudinal or altitudinal shift of forest-steppes.

Megjegyzések:Aim We evaluated stands of the invasive grass, Sporobolus cryptandrus in its native North American range and its non-native European range, where it is a recent invader. Our aim was to reveal how the species' increasing abundance affects functional diversity and the ecosystem service-provisioning capacities of plant communities in both ranges. Location Sand grasslands in the Kiskunsag, Hungary and in Montana, USA. Methods All vascular plant species and their relative abundances were recorded in a stratified random manner in 1 m x 1 m plots in each range, using the following cover categories of Sporobolus as strata: 1%-25%, 26%-50%, 50%-75%, and 75%-100%. The functional characteristics of the plant communities in the two continents were compared. We performed comparisons of the communities both with and without including Sporobolus. Results Increasing Sporobolus cover resulted in a lower functional diversity and species richness, reduced average specific leaf area and increased the height of whole plant communities in both ranges but these effects were significantly stronger in the non-native stands. Sporobolus also negatively affected the cover of insect-pollinated plant species and the proportion of native perennials, switching the rest of the community from perennial-dominated to annual-dominated. In plant communities without Sporobolus, increasing Sporobolus cover led to a higher specific leaf area and seed mass in both ranges, but average height was decreasing along the Sporobolus abundance gradient in the native range, whereas it was increasing in the non-native range. Conclusions The spread of Sporobolus, away from its native range, leads to the impoverishment of host communities and compromises the biomass and floral resource-provisioning capacity of the vegetation to higher trophic levels. Tackling the spread of this new invader should therefore be a priority task.

Megjegyzések:Plant species performance in rangelands highly depends on the effect of grazing and also on the occurrence of unpalatable benefactor species that can act as biotic refuges protecting neighboring plants from herbivores. The balance between facilitation and competition may changes with the benefactor density. Despite the high number of studies on the role of biotic refuges, the density dependent effects of unpalatable herbaceous plants on the performance of other species, and on the habitat heterogeneity of rangelands are still unclear. Therefore, we performed a study to test the following hypotheses: (i) Performances of understory species follow a humped-back relationship along the density gradient of the unpalatable benefactor species. (ii) Small-scale heterogeneity of the vegetation decreases with increasing benefactor density. We studied meadow steppes with medium intensity cattle grazing in Hungary. We surveyed understory species' performance (number of flowering shoots and cover scores) along the density gradient of a common, native unpalatable species (Althaea officinalis). Our findings supported both hypotheses. We found unimodal relationship between the benefactor cover and both the flowering success and richness of understory species. Moreover, small-scale heterogeneity declined with increasing benefactor cover. In this study we detected a humped-back pattern of facilitation along the density gradient of an herbaceous benefactor in pastures. Indeed, this pattern was predictable based on such conceptual models like ?consumer pressure-abiotic stress model', ?humped-back model', ?intermediate disturbance hypothesis' and ?disturbance heterogeneity model'; but until now the validity of these relationships has not been demonstrated for herbaceous species. By the demonstration of this effect between herbaceous species we can better forecast the responses of grasslands to changes in management.
