Project summary:
Mountains represent the specific phenomenon, which together with broken relief, various geology, miscellaneous climatic and
soil features contribute to exceptional habitat variability. Under specific conditions the diverse mosaic of vegetation
types developed, with abundance of rare, relic and endemic taxa. The aim of the research is the study of biodiversity in
the Carpathians on population and community level. Project focuses on mutual interactions between individual plant species,
as well as between communities and abiotic environment in various space-temporal scales. The research is aimed at analysis
of ecological and floristic variability of selected high-altitude ecosystems, in relation to abundance of floristic elements,
functional types etc. Results will be interpreted within wider historical and evolutionary context. To achieve the goals,
the traditional methods used in ecological studies and the modern ones used in molecular genetics, taxonomy, bio- and
geoinformatics and biostatistics were chosen.

Project summary:
Recently a considerable attention is devoted to the research of grassland vegetation
which represents the most widespread type of non-forest vegetation in Slovakia. Species-rich grasslands are
threatened by numerous factors and their biodiversity in some regions decreases gradually. The project
logically follows several previous projects focusing on grassland vegetation in Slovakia (VEGA 5084, APVV 5804).
The main goal is through the implementation, broadening and completion of the results obtained by previous
grassland projects to evaluate and elucidate the present state and temporal changes in grassland vegetation
using the modern statistical methods. These analyses should result in a comprehensive synthesis of Slovak
grassland vegetation which could serve to a wide spectrum of users. Results will be summarized in the fifth
volume of edition Plant communities of Slovakia. It will contain detailed characteristics of meadow, pasture,
halophilous and fringe vegetation.

Project summary:
Tephroseris longifolia subsp. moravica is a critically endangered endemic taxon of Carpathian flora included in
the European list of important species. Altogether there are 14 recent localities, 6 of them in the Moravia and
8 in Slovakia. Even when the abundance of its populations has been monitored during last 3 years, reliable
information on its life cycle is still missing and the interpretation of the results is vague. The recorded
population abundance is very variable, what complicates the evaluation of population development and
establishment of effective conservation means. The demographical analysis will ensure the relevant information
for proposal of optimal monitoring and objective evaluation of the recent knowledge. Moreover, we plan
cultivation experiments, seed bank survey, estimation of ecological requirements and limiting factors of the
taxon. The phytosociologica material will enable the ecological analysis based on interspecific associations
and ecological indicator numbers.

Project duration: 2009 - 2011
Grant agency: VEGA 2/0030/09
Project summary:
The focus of the proposed project is on endangered saline habitats in Pannonia. A complex
approach combining methods of synecology and biosystematics will be used to analyse changes and endangerment
of saline habitats. Model biotopes include usually degraded Slovak saline habitats and relatively natural
saline sites in Hungary, Austria and Serbia. The zonation of saline vegetation caused by various salt content
will be studied on transects. Experimental restoration of Camphorosmetum annuae community will be
tested in the field experiment on permanent plots. Taxonomy and ecology of the groups of Puccinellia distans,
Chenopodium chenopodioides and Heleochloa occurring on natural as well as on secondary saline
biotopes will be studied. Except karyological and morphological variation of these groups, distribution and
ecology of cytotypes will be analysed. Further study of the distribution and synecology of other rare saline
plants will extend our knowledge of recent condition of saline communities in Pannonia.
- Ecological and phytosociological characteristics of halophytic communities Beckmannietum eruciformis, Camphorosmetum annuae, Hordetum hystricis and Plantagini tenuiflorae-Pholiuretum pannonici in Pannonia.
- Examination of historical and recent distribution of selected halophytes in Slovakia and Pannonia: Beckmannia eruciformis, Camphorosma annua, Heleochloa alopecuroides, Hordeum hystrix, Chenopodium chenopodioides, Ch. rubrum, Pholiurus pannonicus, Puccinellia limosa and P. distans.
- Evaluation of vegetation zonality in the Kamenínske slanisko Nature Reserve with respect to relationships of the species and communities to soil salinity.
- Experimental reconstruction of Camphorosmetum annuae in the Kamenínske slanisko Nature Reserve.
- Cytogeografical analysis of the Puccinellia distans group in Pannonia including assessment of sympatric/alopatric distribution of the particular taxa and cytotypes. Interpretation of relationships between ploidy level and morphological variation of the cytotypes. Evaluation of ecological differentiation of Puccinellia distans, P. limosa and P. peisonis cytotypes using transplantation experiments, analysis of their relationships to plant communities and ecological conditions in localities as well.

Project duration: 2007-2009
Grant agency: VEGA 1/0836/08
Project summary:
On the top of the freshwater food chain is Otter (Lutra lutra L.). It is also known as both keystone and umbrella
species. Nevertheless, we still have limited knowledge on some basic aspects of Otter population ecology, ecological niche
and conservation management. Submitted project is aimed at spatial analyses of Otter habitat requirements on the three
Slovak rivers (Hron, Turiec, Rajcianka). These rivers provide probably the most suitable habitats for Otter in Slovakia and
are sufficiently different in size, landscape context and other habitat variables. Main project goals are: to explore the
effects of selected habitat variables on the presence/absence of Otter and to clarify the relationships between abiotic and
biotic variables, to study the relationships between micro- and macrohabitat variables, to assess the relative importance of
these relationships, their strength and spatial scaling with both statistical and visual interpretations using 3D tools
(GIS analyses).

Project duration: 2006 - 2008
Grant Agency: VEGA 6057/26
Key words: Biodiversity, Malá Fatra Mts, phytosociology, relict plant communities, Western Carpathians
Project summary:
Despite high diversity and atractivity, the vegetation of the Malá Fatra Mts has not been studied thoroughly
up to now. Extraordinary habitat diversity, position on the boundary of important biogeographic units,
at the crossroad of migration routes and, consequently, also great species richness characterize the
Malá Fatra Mts as one of the most interesting and most valuable territories in the Western Carpathians.
It represents an outstanding region which belong to the European Union NATURA 2000 Network of Protected
Areas. Main goals for this project are as follows: sampling of phytosociological and ecological data on
the poorly explored non-forest plant communities; their temporal and spatial comparisons; publication of
a detailed review of non-forest vegetation of the Malá Fatra Mts; evaluation of the importance of results
in terms of biogeography, ecology and nature conservation and management recommendations for the Malá Fatra
National Park. Anthropogenic pressure on the nature is getting stronger and this is the reason of great
importance of this theme.
Results 2006:
Acidophilous communities of dwarf-shrub heats dominated by ericaceous species
(Empetraceae, Ericaceae, Vacciniaceae) of the Malá Fatra Mts was analysed and compared with
similar vegetation within the Western Carpathians in published paper. Next volume of the edition
Vegetation of Slovakia (4th) dealing with high mountain vegetation was finished with support
of this project. Relations between vegetation, relief, elevation and exposition were analysed on transect
from montane to subalpine belt (700-1700 m n. m.). Digital model of studied area is under preparation.

Duration of the project: 2005 - 2007
The contemporary knowledge on spatial and temporal distribution and indication ability of macrophytes in watercourses and alluvial aquatic biotopes of Slovakia cannot be considered as sufficient. Therefore, we have defined the project aims as follows:
- i/ to acquire the relevant data on spatial distribution and abundance of macrophytes in relation to the ecological conditions of habitats and human impacts in some selected Slovak watercourses and alluvial wetlands using the Koehler's semi-quantitative method;
- ii/ to enrich recent knowledge on autecology of macrophytes for the assessment of disturbed and natural habitats;
- iii/ to detect changes in both distribution and abundance of macrophytes in selected watercourses and alluvial wetlands using older vegetation and ecological data.

Key words: grassland vegetation, syntaxonomical revision, formalized classification,
effect of management and environmental factors
Project summary:
Mesophilous and xerophilous grassland vegetation covers substantional area of Slovakia and recently has been
subjected to marked changes related to land use alteration. Since the introduction of Zurich-Montpellier
phytosociological approach many plant communities were described mostly in regional context without a broader
evaluation of their relationships to the existing syntaxonomical system. The main task of the project is to
summarize the recent knowledge on grassland vegetation in Slovakia and to make it accessible for
international synthesis as well as for practical utilization (nature conservation and landscape planning).
Firstly, it is planned to revise the current approach to grassland classification and to evaluate the
relevancy of the syntaxa description. A new national classification will be proposed thereafter based on the
results of modern analytical and synthetic methods that may increase its transparency and objectivity
concerning the delimitation of vegetation units. A comprehensive stand analysis as to the variability of
species composition related to the environmental factors and to the management type will be used as a base
for the detailed synecological characteristic. The project will result in proposing criteria for the
identification of grassland communities which could serve as a basis for the elaboration of a widely used
computerised expert system.
Results:
The Slovak phytosociological database of grassland vegetation was extended by all individual unpublished
relevés from insufficiently known regions (1500), unpublished relevés gained from external sources (2000)
and recently compiled published relevés (2500). In addition, the geographical position of 3000 relevés was
included.
The field phytosociological survey foccussed on selected regions of Slovakia and a substantial set of relevés
was collected: Starohorské vrchy Mts. (320 relevés), Biele Karpaty Mts. (320 relevés), Poľana Mts.
(670 relevés) and Javorie Mts. (70 relevés). The Slovak Central Phytosociological Database was extended
by both individual unpublished and accessible published relevés and recently it contains 7748 physociological
relevés of mesophilous and xerophilous grassland vegetation. The numerical classification of relevés
belonging to the class Festuco-Brometea was performed. It identified six main clusters at the alliance level.
Vegetation-environment relationships were studied on a transect in the Považský Inovec Mts. and the effect of
grassland management on species diversity was studied in the Poľana Mts.

Duration of the project: 2005 - 2007
Grant Agency: APVT-51-015804
Key words: Central phytosociological database, expert system, formalized classification,
grassland vegetation
Project summary:
The project follows recent activities devoted to the mapping of grasslands (by Daphne - Institute of
Applied Ecology) and mapping of biotopes (for the Natura 2000). It is suggested to involve numerous
scientists in the field of grassland vegetation research and use their experience through consultations.
The project can logically be divided into two main stages. During the first stage, a large phytosociological
material will be collected on grassland vegetation in Slovakia. The central database of phytosociological
relevés (http://ibot.sav.sk/cdf/) is intended to be completed. As we suggest that various regions of Slovakia
will be irregularly represented in the database, we plan to carry out an intensive supplementary data
collection so that a sufficient number of relevés will be collected from all phytogeographically distinct
areas and all main grassland vegetation types will be covered.
The second stage is aimed at the elaboration of the collected phytosociological material. Initially it is
important to revise the diagnostic species used in the current standard classification and evaluate the
relevancy of delimitation of individual syntaxa. For this purpose a formalized classification approach will
be used which was successfully applied in the neighboring countries for vegetation evaluation of large areas.
The new classification based on precisely defined criteria will be compared the traditional approaches and
discussed with grassland researchers. Finally, the classification criteria will be incorporated into the
formalized expert system for identification of grassland communities. The system may be tested in various
environmental conditions and adjusted according to the needs of nature conservancy and landscape planning
institutions.
Results:
The Slovak phytosociological database of grassland vegetation was extended by all individual unpublished
relevés from insufficiently known regions (1500), unpublished relevés gained from external sources (2000)
and recently compiled published relevés (2500). In addition, the geographical position of 3000 relevés was
included.
Recently, the database contains 11 121 relevés of grassland vegetation. The header data of relevés were
inspected and the nomenclature of taxa was unified. The subxerophilous grassland vegetation dominated by
Brachypodium pinnatum and Bromus erectus was analyzed in Central European region. The new method of
cross-validation was proposed aimed at testing of clusters validity in classification results.
Four studies of local grassland vegetation were prepared.

Key words: Veľká Fatra Mts., Western Carpathians, syntaxonomy, regional synthesis
Project summary:
The Veľká Fatra Mts. represents the region with a high diversity of all, climate, relief flora and vegetation.
Numerous syntaxa have been described from this region. Nevertheless, numerous vegetation types still remain
insufficiently known. The widening of knowledge on their structure and distribution should contribute to a more
professional management and conservation of rare and vulnerable plant communities. At the same time the project
should contribute to population mapping of the phytogeographically and endangered taxa of vascular plants with
optimum in non-forest communities.

Despite high diversity and atractivity, the vegetation of the Muránska Planina Mts has not been studied thoroughly up to now. Extraordinary habitat diversity, position on the boundary of important biogeographic units, at the crossroad of migration routes and, consequently, also great species richness characterize the Muránska Planina Mts as one of the most interesting and most valuable territories in the Western Carpathians. It represents an outstanding region which is a candidate for the European Union NATURA 2000 Network of Protected Areas.
Main goals for this project are as follows:
- i/ sampling of phytosociological and ecological data on the poorly explored forest and shrub plant communities and their storage in the central electronic database;
- ii/ their temporal and spatial comparisons (the earlier vs recent data on the territory of Slovakia or Western Carpathians, respectively);
- iii/ publication of a detailed review of forest and shrub vegetation of the Muránska planina Mts including synoptic tables and descriptions of plant communities found;
- iv/ evaluation of the importance of results in terms of biogeography, ecology and nature conservation and management recommendations for the Muránska Planina National Park.

Plant communities with dominant species Calamagrostis arundinacea, C. varia, Carex firma, C. humilis,
Festuca pallens and F. tatrae from the Muránska planina Mts and similar ones from the
Western Carpathians within the large syntaxonomical revisions were compared. The association
Geranio robertiani-Delphinietum elati Kliment et al. 2004, subassociations Pulsatillo
slavicae-Caricetum humilis campanuletosum xylocarpae Uhlířová et Bernátová 2004 and Minuartio
langii-Festucetum pallentis campanuletosum xylocarpae Kliment et al. 2005 based on relevés from
the Muránska planina Mts were newly described. Riparian communities of the alliance Petasition
officinalis were completely evaluated and classified.
Detail characteristics of 30 aquatic and wetland communities (Lemnetea: 2; Potametea: 8;
Phragmito-Magnocaricetea: 20), found in course of the project, were published. The lists of
plant communities, vascular plants, mosses and partially lichens were completed. The most interesting
findings of the vascular plants and mosses and their coenological characteristics were also published.
High floristic and vegetation (biotope) diversity was confirmed. Warning message on spreading of several
invasive species (Bunias orientalis, Juncus tenuis) was highlighted.

The processes of succession and spontaneous invasion of shrubs and trees were studied on several transects and permanent plots. The first data have been obtained and results were published from locality in inland sand dune pine forest near Malacky (Borská nížina) and with co-opertion (project VEGA nr. 0126) on transect Príslopy (Poľana Mts.). The spatial and temporal pattern, relations between overstorey trees and understorey vegetation, were studied due direct measured data on microhabiatas e.g. soil moisture, soil temperature, snow cover, distribution of lichens…, dendrochronological data and with help of air-photos, digital terrain model and GIS techniques.
A large data (relevés) were add in database and analysed using numerical classification. The entirely revised mountain vegetation with dwarf pine (the class Roso pendulinae-Pinetea mugo), subalpine communities of deciduous shrubs (the class Betulo carpaticae-Alnetea viridis), and alpine heaths (the class Loiseleurio-Vaccinietea) in the Western Carpathians. A conceptual scheme was prepared for shrubs and thickets (the classes Rhamno-Prunetea, and Franguletea).

Key words: demography, genetical structure, spruce colonization, succession,
understorey vegetation
Results:
The effects of spruce colonization upon the understorey vegetation were studied along a transect in
locality Príslopy (Poľana Mts.). The mesotrophic and oligotrophic variants were distinguished within
the identical spruce-beech succession series, which differed by both, the initial phase and course,
but led to the same outcome phase. The datailed measurements of climatical, biological, pedological
and soil-microbiological factors were performed along the transect. The variability of understorey
vegetation was affected mainly by percentage cover of needles and plant litter along with the light
availability. Relations between spruce fertility, seed rain, seedlings establishment and environmental
variables were confirmed.

Duration of the project: 2002 - 2004
The main contribution of the proposed project
is a critical re-evaluation of anthropical influence on flora and vegetation in
synanthropic habitats in the estate interior and exterior (flooded sand or gravel
pits, roads, dikes, meadows, fields, dumps, village interior and exterior etc.).
The published and not published data will be used, as well as the newly gathered data.
Using modern methods of ecological and numeric evaluation they will give new up-to-dated
pieces of knowledge about the impact of human activities on the vegetation. Species
composition, ecological characteristics and distribution of plant communities in
man-made or man-influenced habitats will be established. The results will fill the gap
in knowledge of the characteristic vegetation in synathropic habitats in one of the most
remarkable regions of Slovakia, exploited by the human kind in the past, at present, but
especially in the future. Diversity and synathropisation degree of vegetation, occurrence
or spreading and/or retreat of invasive species, occurrence of rare and endangered
species will be established. Just the secondary habitats may serve as a refuge of many
rare and endangered species in this region.
New pieces of knowledge about anthropically influenced habitats will became a part of
knowledge basis inevitable for deciding bodies at management of various activities in
that territory in order to preserve, as much as possible, biodiversity of this very
valuable area, a part of which is under protection of a unique wetland of the world
wide significance.

Duration of the project: 2000 – 2002
A new project assign some crucial aims, such as to prepare an exhaustive survey of plant communities from five-six
selected classes of the group of grassland- and herbaceous vegetation i.e. meadows, pastures, salt- and xerophilous
vegetation for printing. Here to direct the attention at the synthesis and syntaxonomical revision in the
communities of xerotherm grasslands (class Festuco-Brometea) and fringes (Trifolio-Geranietea) as well as
to elaborate a syntaxonomical survey of meadow (Molinio-Arrhenatheretea) and pasture (Calluno-Ulicetea)
communities.
Next product of project will be monitoring of present status in the
halophilous vegetation of the class Puccinellio-Salicornietea
occurring in the southern and eastern part of Slovakia (Pannonicum).
This real status will be compare with old data and results of comparative
research provide data for nature conservation of the rest localities of
inland salt vegetation in Slovakia.

Duration: 1999 - 2001
The principal aim of the project is to find and to explain the vegetation dynamics in relation to spontaneous change of determining ecological factors at the Morava river floodplain using the method of permanent plots. Permanent plots were selected with respect to existing plots in this way that they characterise broad scale of plant communities, especially for the Morava river floodplain typical ones. Repeated investigation of vegetation is concentrated on various aspects of species composition of vegetation, such as species richness, abundance of species, species diversity and species turnover. Permanent plots are situated in periodically flooded area, and the communities of interest represent various items of freshwater succession series of eutrophic water, consequently the water regime, in particular dynamics of flooding, ground water, and soil moisture are registered.

Mapping of macrophyte vegetation in the Danube River (part Sap-Štúrovo) |
|
|
Construction of the Gabčíkovo hydropower station caused changes in hydrological regime and created a new situation in distribution of macrophytes, as well as in vegetation along both banks. The aim of this study was to map present distribution of macrophytes along fixed sections and to prepare foundations for future monitoring. Semi-quantitative values of macrophytes were compared with abiotic data and some relations between distribution of plants end ecological situations were observed.
Distribution of macrophytes in Slovak reach of Danube was mapped in three types of water bodies with different
environment and management:
i/ The Old Danube River (1839-1811 rkm),
ii/ the anabranch system,
iii/ the seepage canal.
Succession and content of aquatic plants changed in dependence on hydrological regime. Succession of
macrophytes started in the Old Danube. Zannichellia palustris is the first hydrophyte, which overgrows the
riverbed covered by a thin layer of fine sediment. Temporary denuded pools on flat littoral provided favourable
conditions for succession. Semi-natural anabranch system preserved high biodiversity, 24 species in three backwaters
were recorded. Also the new artificial habitat - seepage canal, is rich in species. Some of rare and endangered species,
such as Groenlandia densa, Hippuris vulgaris, Apium repens and Characeae found here suitable habitats.
The distribution of neophyte Elodea nuttallii rapidly increased in the Slovak part of Danube flood plain.

Mapping of macrophyte vegetation in the Ipeľ River (part Zelené-Pinciná) |
|
|
The aquatic macrophyte vegetation along selected part of Ipeľ River and adjacent tributaries situated between Zelené and Pincina villages was investigated in July and August 2000. In the 88 river sections of various length (2-1000 m; overall length was 14.3 km) all macrophytes were mapped and their quantitative values using standard Kohler´s method were estimated. By all section some abiotic data, such as character of banks and sediment type at the bottom, flow of water, etc. were recorded. The distribution of plants was related to the abiotic data and 3 types of floristic-ecological zones were recognised and shortly characterised. The results will be published in Hrivnák, R., Valachovič, M., Ripka, J., 2001: Relation between macrophyte vegetation and environmental conditions in the Ipeľ River (Slovakia) - case study. Arch. F. Hydrobiol., (in press.)
The main objective of the project in future is mapping of macrophyte vegetation in the Ipeľ River with special attention on water quality in border section. Ipeľ is a border river between Slovakia and Hungary. Aquatic macrophytes represent there a good indicator for assessment of quality of water bodies senzu Water Framework Directive of the European Community. The inventory of macrophytes in Ipeľ River was studied by standard methods - qualitative and quantitative mapping of aquatic plants in hard and fast lines (defined stretches). The ecological status of river will be described and display in maps 1: 25 000 using GIS methods. The monitoring in future can give an available data for pollution control and for studies on relationship between environmental parameters and the aquatic vegetation. The realisation of project will be an example of trans-boundary environmental impact assessment.

The Joint Danube Survey (JDS), organised by the International Commission for the Protection of the Danube River (ICPDR), is aimed at producing comparable, accredited water quality information for the whole length of the Danube River. The survey will be carried out by an international team of experts using two ships ARGUS and SZÉCHÉNYI from Germany and Hungary. The cruise will commence on 14 August from Regensburg in Germany and make its way through Austria, Slovakia, Hungary, Croatia, Yugoslavia, Bulgaria, Romania, Moldova and Ukraine until 20 September. The purpose of the JDS is to contribute to several objectives of the ICPDR, i.e.:
- to identify and confirm specific pollution sources
- to screen the pollutants as specified in the proposed EU Water Framework Directive
- to provide a forum for riparian/river basin country participation for sampling and inter-comparison exercises
- to facilitate specific training needs and improve in-country experience
- to promote public awareness
During the JDS samples will be taken from 98 sampling stations (for more details,
cf. Event Calendar). Sampling at each station includes five different sample types
(water, sediment, biology, suspended solids and mussels), each with different
determinand list.
Samples, collected within a few days, will be transported by a shuttle service to
the JDS Central Storage Facility and then re-distributed for analyses of specific
sets of parameters to the JDS Reference Laboratories, selected on the basis of an
international tender. Parallel samples will stay stored in the JDS Central Storage
Facility for future processing.
One part of each sample taken within a particular country will be analysed also in
the National Reference Laboratories (NRLs) in Germany, Austria, Czech Republic,
Slovakia, Hungary, Croatia, Yugoslavia, Bulgaria, Romania, Moldova and Ukraine.
Representatives of the NRLs (JDS National Teams) will be on board during the collection
of the respective samples in their countries and responsible for a proper transport
to their laboratories.
