Megjegyzések:Studying the relationship between biodiversity patterns and processes in vegetation has been at the centre of interest in vegetation ecology for several decades. By studying the biomass of loess and alkaline grasslands along a water and salinity gradient, we aimed to analyse species diversity and Grime`s competitor-stress tolerator-ruderal (CSR) functional strategy patterns. We aimed to test the following hypotheses: i) The biomass and species richness scores and the species composition are significantly different between the sampled grassland community types. ii) The sampled communities are well separated based on the CSR strategy spectrum. iii) The amount of green biomass and litter are positively correlated with competitiveness and negatively with stress tolerance. The biomass and species richness scores and the species composition of the sampled communities along the sampled gradients were significantly different; the highest species richness, evenness and Shannon diversity values were found in loess grasslands. The highest level of litter accumulation was found in alkaline meadows. The communities were well separated in the ordinations but surprisingly, calculation of coordinates for CSR strategy types have not shown clear separation of the grassland community types. All the communities were proven to be characterised by a high level of stress (located in the right corner of the CSR ternary diagram), but they markedly differed in the magnitude of competition and levels of disturbance expressed in the differences of ruderality. These results might suggest that even in highly stressed communities the community composition is strongly dependent on the differences in disturbance intensity (e.g., intensity and duration of grazing) and it is also strongly influenced by the competitive ability of constituting species.

Cím:Effect of burning of evergreen savin juniper and herbaceous patches on soil : seed banks, chemical and biological properties / Reza Erfanzadeh, Ali Ansari, Mohammad Jafari, Péter Török
Dátum:2023
ISSN:2351-9894
Megjegyzések:The coniferous shrub species Juniperus sabina (savin) is widespread in mountainous regions of Eurasia. The species produces large amounts of fire-prone plant mass in its habitats. The aim of this study was to assess the effect that burning of savin shrubs has on the soil seed bank (SSB), the microbial respiration and the amount of organic matter under its canopy. In each of three sampling areas, four individuals of savin were randomly selected. Under each of these individuals and on adjacent herbaceous control patches, soil samples were taken from 0 to 5 cm and 5-10 cm depths for SSB, biological and chemical analyses. The sampling was repeated after burning the canopy. We found that the immediate effects of burning on the SSB and on the biological and chemical soil parameters were significantly negative. In particular, SSB density, magnitude of microbial respiration and amount of organic matter were significantly decreased after savin canopy burning in 0-5 cm depth, while these changes were less pronounced on the burned herbaceous patches. Hence the restoration of gaps created by burning savin cannot rely on the SSB. Furthermore, alkalization of the soil and decreased soil quality caused by savin burning might hamper the vegetation recovery even in the medium to long run.

Megjegyzések:Grasslands are ubiquitous globally, and their conservation and restoration are critical to combat both the biodiversity and climate crises. There is increasing interest in implementing effective multifunctional grassland restoration to restore biodiversity concomitant with above- and belowground carbon sequestration, delivery of carbon credits and/or integration with land dedicated to solar panels. Other common multifunctional restoration considerations include improved forage value, erosion control, water management, pollinator services, and wildlife habitat provisioning. In addition, many grasslands are global biodiversity hotspots. Nonetheless, relative to their impact, and as compared to forests, the importance of preservation, conservation, and restoration of grasslands has been widely overlooked due to their subtle physiognomy and underappreciated contributions to human and planetary well-being. Ultimately, the global success of carbon sequestration will depend on more complete and effective grassland ecosystem restoration. In this review, supported by examples from across the Western world, we call for more strenuous and unified development of best practices for grassland restoration in three areas of concern: initial site conditions and site preparation; implementation of restoration measures and management; and social context and sustainability. For each area, we identify the primary challenges to grassland restoration and highlight case studies with proven results to derive successful and generalizable solutions.

Cím:Restoration of open ecosystems in the face of climate change / Csaba Tölgyesi, Aveliina Helm, Jayashree Ratnam, Fernando A. O. Silveira, Peter Török
Dátum:2024
ISSN:2351-9894
Megjegyzések:Open ecosystems occur all around the world in various forms including temperate and tropical grasslands, savannas, shrublands, heathlands, among others. They are home to unique biodiversity, provide key ecosystem services and sustain traditional livelihoods of nearly two billion people. In the face of ongoing climate change, practitioners aiming to restore open ecosystems need the support of the scientific community more than ever. The aim of this Special Issue (SI) is to provide an attention-grabbing collection of high-quality publications addressing the growing challenges of open ecosystems restoration. The SI contains 14 papers that fill various, often interdisciplinary knowledge gaps. Three papers deal with the challenges of identifying the right target states, including the genetic composition of constituting plant species, for restoration under changing environmental conditions and competing stakeholder interests. Five papers advance our understanding on the appropriate timing and methodological toolkit to actively ignite re-assembly of the target plant communities, while two papers focus on situations where spontaneous processes can still also be relied on. The interaction of open ecosystems health and recovery with higher trophic levels, particularly grazers, is also discussed in three papers. Finally, a review paper systematically identifies further knowledge gaps, such as the role of soil microbes in grassland recovery and makes clear guidelines how to fill them. Due to the variety of topics and the rigorous content, this SI provides strong support for open ecosystems restoration policy and practice under the UN Decade on Ecosystem Restoration and beyond.

Cím:Forest edges revisited : species composition, edge-related species, taxonomic, functional, and phylogenetic diversity / Khanh Vu Ho, Mirjana Ćuk, Tijana Šikuljak, György Kröel-Dulay, Zoltán Bátori, Csaba Tölgyesi, Attila Fűrész, Péter Török, Alida Anna Hábenczyus, Anna Hegyesi, Ladin Z.

Megjegyzések:Although edges are usually considered key areas for biodiversity, previous studies have focused on anthropogenic edges, usually studied edges in relation to forest interiors (disregarding the adjacent non-woody vegetation), and used simple taxonomic indices (without considering functional or phylogenetic aspects). We studied the species composition as well as taxonomic, functional, and phylogenetic diversity of north- and south-facing edges and the two adjacent habitats (forest and grassland) in near-natural forest-grassland mosaics in the Kiskunság Sand Ridge (Hungary) and the Deliblato Sands (Serbia). We found that the species composition of edges was significantly different from that of forests and grasslands, and included species that were rare or absent in habitat interiors. This indicates that the contact of adjacent forest and grassland habitats results in the emergence of a new habitat that deserves scientific attention in its own right. In the Kiskunság, species richness and Shannon diversity were generally higher at edges than in forests or grasslands. In the Deliblato, edges were taxonomically not more diverse than grasslands. Thus, increased taxonomic diversity at edges should not be considered a general phenomenon. In the Kiskunság, forests and edges had higher functional diversity than grasslands, while there were no significant differences among the habitats in the Deliblato. It seems that functional diversity is strongly influenced by canopy openness and the traits of the dominant species. The phylogenetic diversity of woody habitats was higher than that of grasslands both in the Kiskunság and the Deliblato, which probably reflects the different evolutionary age of the habitats.

Cím:Invasion of the North American sand dropseed (Sporobolus cryptandrus) - A new pest in Eurasian sand areas? / P. Török, D. Schmidt, Z. Bátori, E. Aradi, A. Kelemen, A.A. Hábenczyus, P.

Megjegyzések:For the effective control of an invasive species, gathering as much information as possible on its ecology, establishment and persistence in the affected communities is of utmost importance. We aimed to review the current distribution and characteristics of Sporobolus cryptandrus (sand dropseed), an invasive C4 grass species of North American origin recently discovered in Hungary. We aimed to provide information on (i) its current distribution paying special attention to its invasion in Eurasia; (ii) the characteristics of the invaded habitats in Central Europe; (iii) seed bank formation and germination characteristics, crucial factors in early establishment; and (iv) the effects of its increasing cover on vegetation composition. Finally, we aimed to (v) point out further research directions that could enable us to understand the invasion success of this potential invasive species. Field surveys uncovered large stands of the species in Central and Eastern Hungary with most of the locations in the former, especially in the Kiskunsag region. The species invaded disturbed stands of dry and open sand grasslands, closed dune slack grasslands and it also penetrates natural open sand grasslands from neighboring disturbed habitats. Increasing cover of Sporobolus cryptandrus was associated with a decline in species richness and abundance of subordinate species both in the vegetation and seed banks, but a low density of Sporobolus cryptandrus can even have a weak positive effect on these characteristics. Viable seeds of Sporobolus were detected from all soil layers (2.5 cm layers measured from the surface to 10 cm in depth), which indicates that the species is able to form a persistent seed bank (1114 to 3077 seeds/m(2) with increasing scores towards higher abundance of the species in vegetation). Germination of Sporobolus cryptandrus was negatively affected by both litter cover and 1 cm deep soil burial. To sum up, Sporobolus cryptandrus can be considered as a transformer invasive species, whose spread forms a high risk for dry sand and steppe grasslands in Eurasia. We can conclude that for the effective suppression of the species it is necessary: (i) to clarify the origin of the detected populations; (ii) to assess its competitive ability including its potential allelopathic effects; (iii) to assess its seed bank formation potential in habitats with different abiotic conditions; and (iv) to assess the possibility of its suppression by natural enemies and management techniques such as mowing or livestock grazing.
