Ecological relationships between supplementary feeding and baiting in situ and vegetation patterns were studied in the mostly forest landscape of the Western Carpathians. We aimed to test the role of wildlife management practices in alien plants spreading. Altogether 82 localities with diverse hunting facilities stretched throughout several mountai...

Plant species diversity of black alder-dominated forests was studied in three biogeographical regions (Alpine, Continental and Pannonian) of Central Europe. They were represented by regions of the Polish Plain (Continental), the High Western Carpathians and Matricum of the Western Carpathians (Alpine) and the Pannonian lowland (Pannonian). We analy...

Biodiversity hotspots, such as the Caucasus mountains, provide unprecedented opportunities for understanding the evolutionary processes that shape species diversity and richness. Therefore, we investigated the evolution of Primula sect. Primula, a clade with a high degree of endemism in the Caucasus. We performed phylogenetic and network analyses o...

The great book of plants, rocks, minerals and fossils is a unique, richly illustrated work, which in a comprehensive form gives an image of the flora of the whole of Central Europe. The updated texts present in an engaging way information on the life, reproduction, distribution, occurrence of plants and their importance for humans, as well as data...

The paper aims to provide a comprehensive overview of karyological and morphological variability of the Tanacetum corymbosum group in Slovakia. We estimated DNA ploidy level and relative DNA content of 530 individuals (45 populations) using DAPI flow cytometry. The morphological variation was studied by univariate as well as multivariate morphometr...

Field data on the occurrence of the common and cosmopolitan submerged macrophyte Ceratophyllum demersum in relation to the water ammonium content were compared with the response of the plants to different ammonium treatments performed in the laboratory. Ammonium concentrations above 10 µM in the monitored area were found to be a strong limiting fac...

Floodplain forests, as diverse plant communities commonly related to riparian zones, host plant species with various ecological niches and origins. The phytosociological context of floodplain forests has been well described on national level in many European countries, however, there are still regions with relatively poorly known variability of the...

The effects of local and regional environmental variables as well as spatial gradients on the plant species composition of two types of alder-dominated forests (riparian forests and alder carrs) with contrasting connectivity were studied across the Western Carpathians from Hungary through Slovakia to Poland. We used large vegetation (240 sampling p...

The proportion of endemic taxa is a frequently used measure for assesment of biodiversity hotspots within the Carpathians. For confirming of an endemic status of a taxon, a thorough evaluation using modern tools of plant systematics is desirable. Tephroseris longifolia subsp. moravica has been considered to be a Western Carpathian endemic, but a pr...

Our article brings new occurrence data of 34 alien vascular plants in the territory of central Slovakia. Four of them, Caucalis platycarpos, Hibiscus trionum, Kickxia elatine and Xanthium strumarium are included in the recent Red list of vascular plants of Slovakia.

Molecular plant taxonomy methods have helped to introduce new findings to the original concepts of plant evolution in comparison to traditional classification based on morphological, karyological, and ecological characters. The objective of our study was to determine if a new taxonomic concept developed for the Soldanella genus would also change th...

Aquatic vegetation of the mountains and sub-alpine ponds in the Tatra Mountains and adjacent area (Slovakia) has been studied with the aim to provide information about the composition and species richness of macrophytes in relation to environmental factors. Macrophytes were studied in two pond groups: natural ponds of glacial origin and artificial...

Knowledge of seed-bank dynamics and seedling recruitment is crucial for effective in situ conservation of endangered species. Herein, we studied Tephroseris longifolia subsp. moravica in five of nine existing population sites to determine its spatio-temporal regeneration patterns. Our main aims were: (i) to confirm the existence of a soil seed bank...

Altogether 523 taxa of vascular plants were found. Among the recent interesting floristic records belong the following enda...

The degradation of habitats and species loss in freshwaters is far greater than in any other ecosystem. The decline in biodiversity has a strong potential to alter the functioning of the ecosystem and the services they provide to human society. Therefore, there is an urgent need for accurate information on patterns and drivers of diversity that cou...

The information on both the catchment land use and catchment area has the potential to be adopted into the conservation and management of ponds. There have been, however, few attempts to describe the effects of land use acting at various spatial scales on ponds and the studies were restricted to specific categories of ponds. This paper presents a s...

The genus Soldanella (Primulaceae) is endemic to European mountain ranges and harbors up to 20 taxa. Species are segregated into two sections, Tubiflores and Soldanella, which differ in their morphology and ecology. Karyologiacally has been all taxa reported to be diploids, but with two known chromosome races 2n=2x=38 and 40. Detail distribution of...

Lindernia dubia (L.) Pennell, a Northern-American species, was recently found in two localities in central Slovakia (near Trenč and Štiavnické Bane villages) as a new species for the flora of Slovakia. Individuals of the species grew in wetland vegetation of the class Iso¨eto-Nano-Juncetea in both cases. The second mentioned locality probably belon...

Tephroseris palustris (syn. Senecio palustris) is a circumboreal species with large distribution range. The European part of the recent distribution area extends southwards to central France, Germany, Poland, and Ukraine, while in Great Britain, Czech Republic, Hungary, Slovakia, and Romania, T. palustris has been treated as extinct species. The so...

Most European scurvy grasses (including those of the Carpathian Mountains) belong to the nominate section Cochlearia.
