Halophila johnsonii Eiseman is a shallow-water marine angiosperm which contains UV-absorbing metabolites. Studies on methanol extracts of H. johnsonii by means of HPLC-UV, NMR, HPLC-MS resulted in isolation and identification of seven previously unknown flavone glycosides: 5,6,7,3',4',5'-hexahydroxyflavone-7-O-beta-glucopyranoside (1), 5,6,7,3',4',5'-hexahydroxyflavone-7-O-(6''-O-acetyl)-beta-g...

The spectral signatures of the seagrasses Zostera capricorni, Posidonia australis, and Halophila ovalis were investigated to determine whether species could be discriminated by remote sensing. The spectral reflectance of fouled and unfouled leaf samples collected from marine and brackish habitats at three estuaries in southeastern Australia were measured in the field with a spectroradiometer du...

Seagrass is the most effective ecosystem in absorbing carbon. The ability of seagrasses to absorb CO2 from atmosphere better than terrestrial ecosystems. Image processing methods and information regarding potential carbon stocks seagrass beds can then be used as a basis for managing found coastal areas small islands. This study aims estimate stock waters Kodingarenglompo Island using remote sen...

We have expanded our knowledge of the localities, sites and distribution Amelanchiero ovalis-Pinetum mugo association in Slovenian Alps. Based on phytocenological analyses, shrub belonging to forest vegetation type Alpine mountain pine scrub was divided into two subassociations: peucedanetosum oreoselini hylocomiadelphetosum triquetri. also described four variants within latter association.

Median sternotomy was performed and cardiopulmonary bypass was established using bi-caval cannulation. Cardiac standstill was obtained with antegrade cardioplegia after cross-clamping the aorta. The caval tapes were snared and the right atrium (RA) was opened. An incision was made in the fossa ovalis and was extended into the left atrium (LA). Stay sutures were placed on the edge of the incisio...

Protozoan and nematode infections of Periplaneta americana in Bulgaria were investigated. Five protozoan and 2 nematode parasites of P. americana were recorded: Endamoeba blattae, Amoeba sp., Lophomonas striata, Nyctotherus ovalis, Balantidium blattarum, Hammerschmidtiella diesingi and Leidynema appendiculatum. Parasite prevalence varied from 1,6% for Amoeba sp. to 32,8% for nematodes. Biometri...

This paper presents new records and noteworthy data on the following taxa in SE Europe adjacent regions: saprotrophic fungi Psathyrella typhae, Stropharia halophila, mosses Bryum klingraeffii Buxbaumia viridis, liverwort Scapania gymnostomophila, fern Matteuccia struthiopteris, monocots Galanthus nivalis, Listera ovata, Ophrys apifera, dicots Astragalus dasyanthus Paeonia officinalis subsp. ban...

A novel, Gram-staining-negative, non-pigmented, rod-shaped, strictly aerobic, extremely halophilic bacterium, designated strain IA16(T), was isolated from the mud of the hypersaline Lake Aran-Bidgol, in Iran. Cells of strain IA16(T) were not motile. Growth occurred with 2.5-5.2 M NaCl (optimum 3.4 M), at pH 6.0-8.0 (optimum pH 7.0) and at 30-50 °C (optimum 40 °C). Phylogenetic analysis based on...
