Abstract In the submitted paper, we have summarised the results of a research that was realised in the locality of the Báb forest (village Veľky Báb, Nitra loess upland). In the area of Báb forest, we were able to document 134 higher plants on 32 permanent research plots (PRP) during 2013. One hundred and twenty-three taxa were documented in the PRP areas situated on clearcuts, whil only 75 were found in the PRP areas located in forest covers. On PRP of clearcuts, there was the highest cover of herb layer; on the other hand, in the forest cover, there was a higher cover of shrub and tree layer. The highest differences in life-forms between two groups of PRP (clearcuts/forest) were detected by hemicryptophytes and terophytes. On all the 32 areas, the biggest number of species belonged to the indigenous species and apophytes. The biggest differences between forests and clearcuts are shown in a representation of C- strategies. The species composition of the Báb forest has changed mainly due to creation of clearcut areas in November 2006. The logging created suitable conditions for the penetration of heliophilious non-indigenous species from the surrounding (mainly anthropogenic) habitats. That is why there are largely synanthropic and non-indigenous taxa represented on permanent clearcut areas, which are spreading further to the forest cover as well as distant areas of the Báb forest.

Abstract We present the results of a research which was realized in June 2011 on the location of the Bab forest (SW Slovakia, Nitra loess upland). On 30 permanent areas in the Bab forest there were 117 taxa of higher plants registered. On 12 permanent clear-cut areas were situated 87 taxa and on 18 forest areas 61 plant taxa. a higher number of species was registered on permanent clear-cut areas where heliophilous plants dominated. On clear cuts was also a bigger cover of herbs. There were dominated hemicryptophytes and terophytes unlike forest areas where nano- and makrofanerophytes dominate and where tree and shrub layers have a high cover. The highest frequency of occurrence on clear-cuts (100%) achieved species Geum urbanum and Pulmonaria officinalis and in the forest stand the forest taxa Mercurialis perennis, Hedera helix and Melica uniflora. On all 30 areas dominated indigenous species and apophytes. Four new clear cut areas and 6 open stands arose after realisation of clear and shelterwood fellings in November 2006 and subsequently a change of plant species composition occurred. The logging created suitable conditions for penetration of non-indigenous species from the surrounding (mainly anthropogenic) habitats. That is why there are largely synanthropic and non-indigenous taxa represented on permanent clear-cut areas, which are spreading further to the forest stand as well as distant areas of the Bab forest.

In the fresh waters of Sardinia (Italy), the non-indigenous crayfish species Procambarus clarkii has been reported from 2005, but, starting from 2019, there have been several reports of a new non-indigenous crayfish in southern and central areas of this Mediterranean island, and its morphology suggests that this species may be the marbled crayfish Procambarus virginalis. Forty-seven individuals of this putative species were analyzed, using the mitochondrial gene Cytochrome c Oxidase subunit I as molecular marker to identify this crayfish and investigate the level of genetic variability within the recently established population. Phylogenetic and phylogeographic analyses were carried out on a dataset including sequences from the Sardinian individuals and from all congenerics available in GenBank. Results showed that the new Sardinian crayfish belong to the species P. virginalis. All the sequences belonging to P. virginalis from European countries are identical, with only few exceptions found among Sardinian individuals. In conclusion, this paper highlights the occurrence of a new further alien species in the Sardinian fresh waters, which are already characterized by the high presence of non-indigenous species.

Abstract Solidago graminifolia L. Salisb. is one of the latest species appeared in Romania. Due to the interest for the Solidago species as medicinal plants, we researched its phytochemical composition in comparison with the other three species present in Romania: Solidago virgaurea L., Solidago canadensis L., Solidago gigantea Aiton. Starting from the chemotaxonomic value of flavonoids, and their valuable biological properties, we wanted to analyze these substances from S. graminifolia compared to other Solidago species in Romanian flora. The studied species have a high content of flavonoids (3.44-5.21%). The flavonoid substances identified in the indigenous species of Solidago have a high chemotaxonomic value, each species having a charateristic chromatographic profile, therefore their analysis is useful in the case of adulterations. The qualitative analysis of flavonoids was performed by TLC and HPLC-MS, mean while the quantitative determination was achieved by spectrophotometric method and individual fractions separated by HPLC-MS.

This paper reviews the available knowledge about faunal xenodiversity in Sicilian inland waters (Italy). The aim is to provide an updated checklist and bibliography of those non-indigenous species (NIS) which occur in the island, and to identify possible threats to its native biological diversity. Data were collected through an extensive literature search which encompassed also local journals, books, congress abstracts, and other grey literature. All the collected data were critically revised and, when possible, verified by consulting available collections or through dedicated sampling surveys. Only those data contained in reports indicating precise occurrence localities, which were confirmed by our own observations and\or by at least two independent sources including at least a peer-reviewed publication, were considered as certain. Data in literature that did not meet these criteria were considered doubtful and reported separately as unverified. The information provided by websites has been excluded as it often contains unfounded and\or erroneous data. The fauna of Sicilian inland waters host at present 31 confirmed NIS. In addition, the presence of further 11 taxa is dubious. Among the v<em>erified data</em>, invertebrate and vertebrate taxa are nearly equally represented, with 15 and 16 taxa, respectively. With 16 species, the phylum Chordata is by far the most represented, followed by Mollusca (8 species) and Arthropoda (6 species). Most of these species were detected in the last 30 years due to the lack of previous regular studies on Sicilian freshwaters. With few exceptions (<em>e.g</em>., the recent introduction of <em>Xenopus laevis</em>, the African clawed frog), NIS’ effects on native biota have not extensively studied in the island yet. Although the top-down effects caused by introduced vertebrate taxa are known to deeply modify the native structure of the biota, little information is available on the impacts caused by invertebrate taxa, especially the microscopic ones. The presence in Sicily of 11 nonnative species of bony fish is probably the most impacting threat to autochthonous fauna through predation, competition and hybridisation. The results shown in the paper highlight the importance and the urgency of more exhaustive investigations on NIS in Sicilian freshwaters with special regard to less charismatic taxa whose effects on the native biota have never been evaluated yet.
