A critical revision of charophytes collected in Slovakia from 1887 up to present, based on herbaria specimens, provided us with the opportunity to compile an updated checklist and to revaluate their threat status in order to obtain the current red list of charophytes of Slovakia. The data obtained will fill the gap in knowledge about these macrosco...

In this study, we are testing a proxy for red and far-red Sun-induced fluorescence (SIF) using an integrated fuzzy logic modelling approach, termed as SIFfuzzy and SIFfuzzy-APAR. The SIF emitted from the core of the photosynthesis and observed at the top-of-canopy is regulated by three major controlling factors: (1) light interception and absorptio...

Peatlands are one of the most important ecosystems due to their biodiversity and abundant organic compounds; therefore, it is important to observe how different plant species in peatlands react to changing environmental conditions. Sphagnum spp. are the main component of peatlands and are considered as the creator of conditions favorable for carbon...

Eutrophication of water bodies markedly reduces their recreational and economic use, which in turn compels those interested to pursuing prompt and effective restoration. This also applies to waters with a moderate pool of biogenic resources which, following temporarily increased nutrient alimentation from the catchment area may become eutrophic. Th...

Small waterbodies and oxbow lakes play an important role as hotspots of biodiversity and landscape diversity, supplying a range of ecosystem services. However, they are at risk of disappearing. Thus, there is a need for the threats to their existence to be recognised. In this study we aimed to determine whether land uses within small and larger are...

In natural habitats, clonal plants form interconnected ramet networks of varied sizes. In large and small networks, ramets may be presumed to apply distinct strategies of investing in vegetative growth and sexual reproduction. This very hypothesis was tested in the course of our experiment in the field. The study encompassed 16 patches of white clo...

In Europe peatlands are wetlands of postglacial origin. Because of climatic changes and agricultural activities (i.e. drainage and peat extraction), they are one of the most endangered ecosystems worldwide. Water mites are well known as indicators of changing environments in other ecosystems such as springs and lakes. For our study we selected seve...
