Abstract: Doronicum carpaticum (Griseb. & Schenk) Nyman (Asteraceae) is a subalpine to alpine species considered to be endemic to the Eastern and Southern Carpathians in Romania and Ukraine. A specimen collected by Johann Michael Fuss in the Fagaras Mountains, Romania, and held in the collection of August Heinrich Rudolf Grisebach in Gottingen (GOET) is selected here as a lectotype. Furthermore, its unclear distribution in the Balkan Peninsula, the systematic and morphological relation to Doronicum columnae Ten., as well asa neglected paper by Rezso Soo, are discussed. On the basis of the incipient morphological, ecological and chorological distinction of D. carpaticum from D. columnae, it is suggested to follow Soo and treat D. carpaticum as a subspecies of D. columnae: Doronicum columnae subsp. carpaticum (Griseb. & Schenk) Soo.

Abstract: The present floristic study reports the rediscovery of Astragalus roemeri on Mt. Scarita in the Apuseni Mts, from where it was first reported in 1968. This station is remote from the main distribution of the species, which had been thought to be endemic to the Eastern Carpathians. Although the Scarita-Belioara Natural Reserve is a botanically well-studied area, the species apparently was not seen there for over four decades after its original discovery.

Abstract: A principal objective of this study was to summarise the distribution of Veronica species in Romania, where such an inventory has not existed before. Taxa of Veronica genus were identified in 311 plant associations and 36 subassociations framed in 132 alliances. Of the 311 plant associations, 138 are included in various types of NATURA 2000 Habitats. The review of phytosociological data reveals the presence of Veronica taxa in 42 types of Natura 2000 habitats with scientific significance. Some of these Veronica taxa are characteristic species for alliances (i.e. Veronicion baumgartenii Coldea 1991, Veronico officinalis-Quercion Pop 1971) or differential species at plant association level (Veronico baumgartenii-Saxifragetum bryoidis Boscaiu et al. 1977).

Abstract: This paper aims to present an overview of the Larix decidua Mill. formations in Romania, in terms of phytosociology, sozology and phytohistory. We have analyzed data from the literature regarding the associations containing larch, and their current fragmented distribution in the Romanian Carpathians. The latter is influenced by the ecological requirements of the species, as well as by human influence through deforestation and reforestation. It is assumed that natural populations of Larix decidua are concentrated in five major centres: the Ceahlau, Ciucas, Bucegi, Lotru and Trascau mountains. From the sozological perspective, Larix decidua subsp. carpatica is present on the critical list of vascular plants in Romania as a Carpathian endemic. Regarding the conservation status, information related to this species and to the habitat of Community interest, 9420 Alpine Larix decidua and/or Pinus cembra forests, were extracted from the list of Sites of Community Interest (SCIs). The status of a glacial relict taxon was confirmed by analyzing the palynological sites where it has been recorded. Larix decidua is one of the trees that survived in glacial refugia during the LGM and Late Glacial.

Abstract: Threatened taxa are important for biodiversity conservation but in practice are also used as one of the key criteria in identifying Important Plant Areas. Studies on the Biharia Massif had started two centuries ago, but most data have been gathered since 1970. Even though a few sozological mentions appear in the papers regarding this area, a thorough investigation of the material has not been carried out. Of the 536 cormophyte taxa observed or cited in the area studied, 38 are present on the analyzed Red List, while three are included in the national Red Data Book. Of the 38 taxa, 13 have not been found during recent fieldwork, thus requiring more study. Most taxa have been found or mentioned from the upper part of the Cepelor Valley and the area of the Cucurbata Mare peak, situated nearby. Of the two Natura 2000 sites present on the Biharia Massif, ROSCI0260 has a more important protective value for the plant taxa discussed, although the protection is indirect. Certain protection measures, especially the regulation of grazing and tourism, would be necessary to protect this site.

Abstract: We explored: i) lichen species richness and composition of Pinus mugo shrubs and adjacent habitat types, alpine vegetation and spruce forests and ii) the distribution of lichen species in the P. mugo shrubs in relation to environmental factors. Epiphytic, terricolous, saxicolous and lignicolous lichens were considered. The total number of species and the mean species density in one hectare plots are both lower in the Pinus mugo shrubs than in the other two habitat types. However, P. mugo shrubs harbour 15 species that are not present in the other habitat types. The measured beta diversity revealed that lichen communities from P. mugo shrubs are heterogeneously distributed. The regional to local diversity ratio shows that the species richness of P. mugo shrubs is three times higher than that of a one hectare sampling plot, which is true for the spruce forest, too. This ratio is also higher than in the alpine vegetation. The total species turnover, which shows the number of species that are present in the entire habitat type in addition to the average number of species for one hectare plot, is also high, about 45 species, as in the alpine vegetation, and lower than in the spruce forests. The beta diversity measured with a multivariate approach had higher values in P. mugo shrubs than in spruce forest, when considering the lichens from all substrates. The alpine vegetation had higher species richness of terricolous and saxicolous lichens. Altitude and northing of the slope significantly influence the distribution pattern of lichen species of the P. mugo habitat type.

Abstract: The article describes a new woodland association with the name Festuco drymeae-Abietetum, comprising mixed forest dominated by fir and beech. In the tree layer Abies alba and Fagus sylvatica are co-dominants, with a coverage of up to 75%. The herb layer is dominated by Festuca drymeja Mert. et W.D.J.Koch. Some character species for the alliance Abietion albae Brezina et Hadac ex Hadac 1965 also have a high frequency.

Abstract: The antifungal activity of Allium schoenoprasum (chives) leaf extract was tested in vitro against the following phytopathogenic fungi: Aspergillus niger, Botrytis cinerea, B. paeoniae, Fusarium oxysporum f. sp. tulipae, Penicillium gladioli, and Sclerotinia sclerotiorum. The minimum inhibitory concentration (MIC) was 70-120 microliter/ml, depending on the fungal species. The results were compared to those obtained for Fluconazole (MIC = 80-300 microliter/ml) and synthetic allicin (MIC = 100-160 microliter/ml).

Abstract: Biotechnologies based on microalgal cell cultures have multiple applications in aquaculture, the food industry, health care, environmental management, and production of alternative energy sources. In the present study we investigated the influence of nutritional conditions on bioproductive properties of a local strain of the green microalga Scenedesmus acuminatus, grown in axenic laboratory cultures, in Bold's basal nutrient medium. Increment of nitrate concentration enhanced the biomass production, and increased protein content of the alga. Simultaneous supplement of reduced and oxidized form of inorganic nitrogen (as ammonium nitrate) did not result in an increased dry biomass, but the protein content of algal cells was significantly higher, while the carotenoid content decreased. Nitrogen deprivation increased the carotenoid pigment content of the dry algal biomass. 10 mM KHCO3 as inorganic carbon source increased biomass production, decreased protein content and did not modify significantly the carotenoid content of the alga. A higher phosphate concentration in the medium induced an increment of dry biomass and carotenoid content, but had no relevant influence on protein content. Sulphate enrichment did not modify dry biomass and carotenoid content, but caused a moderate increment of protein amount. Photosynthetic light use efficiency and vitality index of photosynthetic apparatus, evaluated with the method of induced chlorophyll fluorescence, revealed a positive influence of ammonium nitrate and of elevated nitrate content, while nitrate starvation and an excessive phosphate and sulphate supply moderately decreased the functional efficiency of light reactions of photosynthesis.
