Traditional low-intensity farming died out in almost all European countries but is well maintained in the Romanian Carpathians. The main aim of our interdisciplinary study was to document traditional farming systems and local ecological knowledge in the colline and sub-montane zone of the Apuseni Mts and to relate this information to recent grassla...

To understand recent biogeographic patterns of Central European rocky steppes, we inspected phytosociological data from rocky steppes dominated by Carex humilis along an elevation gradient (from 140 to 1,350 m) and in four biogeographic regions (NW Pannonian Basin, Western Carpathians, Transdanubian Mountains and Transylvanian Basin). Due to the ph...

We hypothesize, that replacement of native tree edificators in original hardwood forest by black locust plantation hardly affects fundamental habitat conditions and consequently species diversity of biocoenosis. To verify the hypothesis we selected plain area along small stream with homogeneous habitat conditions originally covered by native hardwo...

Arable fields are among the most widespread habitats in Slovakia, but recently, there have been no studies regarding species composition and structure of weed vegetation in these fields. Therefore, we studied the structure of arable weed vegetation and detected α- and β-diversity. The dataset of 507 phytosociological relevés in different crop types...

The cover of introduced tree species in Europe has recently increased, due to several factors. Attempts to understand the impact of non-native edificator trees on the environmental conditions and diversity of undergrowth have so far been limited to a few studies. In this paper, we analyse the effect of one of the most commonly planted non-native tr...
Article
Biological homogenization is a process of biodiversity loss driven by the introduction and invasion of widespread species and the extinction of specialized, endemic species. This process has accelerated in recent years due to intensive human activities. We focused our study on large areas of forest vegetation that have not yet been intensively stud...

Replacing native forests by alien tree plantations can lead to changes in the species composition of the understory. However, differences in the understory species spectrum can also be a part of the natural variability of forest stands. We have tested the suitability of the twin plots method for an evaluation of the impact of alien trees on the spe...
Article
Even though temperate forests have lower non-native plant species richness and cover in comparison to some other habitats, such as anthropogenically influenced habitats or some grassland habitats, several recent studies from Central Europe suggest that there has been an increase in the numbers and proportions of non-native species in forests. Previ...

Traditional orchards are a valuable feature of the rural landscape and they are specific for regions with scattered settlement such as the Myjava hilly land and White Carpathians. Here, the permanent species-rich grasslands beneath trees were regularly managed in the traditional manner until some were replaced in the 1970’s and 80’s by intensively...

Invasions of alien plants are considered as one of the major threats to the diversity of natural ecosystems. So far only few studies focused on alien species in forests, as they appeared to be more resistant to invasions. Recent studies revealed that it was only a temporary phenomenon and many forest habitats are continually being invaded. All stud...

Recent crisis in biodiversity conservation of high nature value grasslands and failures of the Common Agriculture Policy of the EU ask for new effective solutions. Semi-natural grasslands evolved through a long-lasting low-intensity human land use, thus their biodiversity can be most effectively preserved by simulation of traditional agricultural practices. In the project we focus on a detail analysis of grassland phytodiversity in close relation with its historical development and traditional land use. Carpathian grasslands situated in the Central and Eastern Europe with well maintained traditional rural culture belong to the key study areas. Obtaining of high-value biological, ecological and ethnological data on the selected sites should guarantee the proper interpretation of the gathered traditional ecological knowledge. This can become a valuable scientific material for future adjustment of socio-political mechanisms in the realm of grassland conservation and restoration and sustainable land use.
Project
1. How various types of forest habitats differ in their level of invasion by alien species? 2. What is the relationship between the diversity and equitability of the forest stands and their level of invasion by alien species? 3. How selected factors (type of management, cover of tree layer, vertical structure) affect the distribution and spreading of alien species? 4. Does higher fragmentation of forest patches contribute to the higher presence and abundance of alien species? 5. What is the impact of alien trees in the function of the edificators on the diversity of the forest habitats?
Project
1.The floristic and structural changes of grassland vegetation after the abandonment of traditional management or after the alteration of ecological conditions and succession of vegetation (Poľana Mt., Biele Karpaty Mts., Belianske lúky National Reserve, Kláštorské lúky NR) will be evaluated using the short- and long-term field experiments (repeated phytosociological research, permanent plots monitoring). The goal will be challenged on various spatial scales, from small-scale permanent plots to nationwide scale. The changes of species diversity conditioned by climatic changes will be focused as well. 2. The diversity and changes of the different types of grassland vegetation in connection with the traditional land-use will be compared and evaluated. Within the Western and Central Carpathians, areas with the well-preserved traditionally maintained species rich meadows and pastures will be selected. In addition to the detailed research of the species composition of vegetation, the available information on ecological factors, recent and historical management will be recorded using Geographic Information System (GIS) following the recent and historical data. 3. By means of manipulative experiments to find out the impacts of different types of management on selected non-forest vegetation types. The manipulative experiments and management will help to indicate the optimal management for restoration of species omposition of individual vegetation types changed due to the natural succession after abandoning the traditional management, or due to the changing ecological conditions (including the anthropic impact). 4. According to the results of the field experiments, the particular management proposals will be elaborated generalized for the type of vegetation and for a certain biogeographic region, applicable mostly in nature conservation with respect to the specific occurrence of the rare and endangered grasslands habutats in Slovakia and Central Europe.
