Article
Full-text available
Grassland managers and scientists are increasingly interested in cost-effective alternative ways of grassland biodiversity conservation. Prescribed burning is a promising management tool which should be integrated in the planning of management efforts. In addition, small-scale prescribed burning is an effective fire suppression strategy to decrease...
Article
Grasslands used to be vital landscape elements throughout Europe. Nowadays, the area of grasslands is dramatically reduced, especially in industrial countries. Grassland restoration is widely applied to increase the naturalness of the landscape and preserve biodiversity. We reviewed the most frequently used restoration techniques (spontaneous succe...

This article introduces a Special Issue on biodiversity of Palaearctic grasslands and provides a synthesis of the current knowledge on this topic. Four major categories of grasslands can be distinguished in the Palaearctic biogeographic realm: (a) zonal steppes (in areas too dry for forests), (b) arctic-alpine grasslands (in areas too cold for fore...
Article
Full-text available
The Palearctic steppe biome ranges from the Mediterranean basin towards China, forming one of the largest continuous terrestrial biomes. The literature on steppe ecology and conservation is vast but scattered and often not available in English. We provide a review of some key topics based on a new definition of steppes, which includes also Mediterr...
Article
In biodiversity conservation of agriculture-driven landscapes, grasslands have an outstanding importance; their conservation became a top priority both in research and practice. In many regions, sheep or cattle grazing are the best options for biodiversity conservation. In our study, we compared the effects of cattle and sheep grazing on short-gras...
Article
The most widespread nature-based solution for mitigating climate change is tree planting. When realized as forest restoration in historically forested biomes, it can efficiently contribute to the sequestration of atmospheric carbon and can also entail significant biodiversity and ecosystem service benefits. Conversely, tree planting in naturally op...
Article
Full-text available
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–...
Article
Full-text available
Species abundance distributions (SADs) link species richness with species abundances and are an important tool in the quantitative analysis of ecological communities. Niche based and sample based SAD models predict different spatial scaling properties of SAD parameters. However, empirical research of SAD scaling properties is largely missing. Here,...
Article
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 Hun...
Article
Full-text available
Trait-based ecology is gaining ground nowadays on species-based ecology: the number of research and publication focusing on the ecological role of taxa instead of the species themselves increased significantly in the last two decades. One great advantage of this approach is that communities with different species composition due to great geographic...
Article
We evaluated the stands of the invasive grass, Sporobolus cryptandrus in its native North American and non‐native European range, where it is a recent invader. Our aim was to reveal how the species’ increasing abundance affects functional diversity and ecosystem service provisioning capacities of plant communities in both ranges. Sand grasslands in...

Abstract The Decade on Ecosystem Restoration aims to provide the means and incentives for upscaling restoration efforts worldwide. Although ecosystem restoration is a broad, interdisciplinary concept, effective ecological restoration requires sound ecological knowledge to successfully restore biodiversity and ecosystem services in degraded landscap...
Article
Full-text available
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 a...
Article
Full-text available
Although long-distance dispersal (LDD) events are rare and stochastic, they are disproportionately important and drive several large-scale ecological processes; yet, we have a very limited understanding of their frequency, extent and consequences. Humanity intentionally spreads several species, which is associated with the accidental dispersal of o...

Although long-distance dispersal (LDD) events are considered to be rare and highly stochastic, they are disproportionately important and drive several large-scale ecological processes. The realisation of the disproportionate importance of LDD has led to an upsurge in studies of this phenomenon; yet, we still have a very limited understanding of its...
Article
Full-text available
A decrease in habitat amount and connectivity causes immediate or delayed species extinctions in transformed landscapes due to reduced functional connections among populations and altered environmental conditions. We assessed the effects of present and historical grassland amount and connectivity as well as local habitat factors typical of the pres...

One of the main goals of the EU Biodiversity Strategy for 2030 is to avoid further loss of biodiversity and to restore ecosystems. These efforts can be facilitated by compiling the main research topics related to conservation biology to provide new evidence for the most urgent knowledge gaps, and publicise it to researchers, research funders and po...
Article
The prevailing nature-based solution to tackle climate change is tree planting. However, there is growing evidence that it has serious contraindications in many regions. The main shortcoming of global tree planting is its awareness disparity to alternative ecosystem types, mainly grasslands. Grasslands, where they constitute the natural vegetation,...
Article
Full-text available
Grassland restoration is gaining momentum worldwide to tackle the loss of biodiversity and associated ecosystem services. Restoration methods and their effects on ecological community reassembly have been extensively studied across various grassland types, while the importance of post-restoration management has so far received less attention. Grass...
Article
Full-text available
A fundamental question in community ecology is how the quantity of floral resources affects pollinator activity and how this relates to the structure and robustness of pollination networks. The issue has been mainly addressed at species level, while at community level several questions are still open. Using a species‐rich semi‐natural grassland as...
