Global climate change and increased land use lead to the loss of biodiversity at all levels organization living organisms – ecosystems, species, landscape population, genetic, molecular biological levels, etc. The reaction plants anthropogenic impact, according experts, may be even stronger than postglacial changes. A shift in thermal isotherm will cause either move adapt, or disappear. Endemic...

Extracts and juices of cultivated and wild fruits belonging to the families Rosaceae, Grossulariaceae, Moraceae, Berberidaceae, Polygonaceae, Caprifoliaceae and Cornaceae were examined for their growth reducing activity on four bacteria (Bacillus subtilis, B. cereus var. mycoides, Escherichia coli and Serratia marcescens). In vitro antibacterial activities were evaluated by microdilution plate ...

Liquid–liquid chromatography (LLC) is a preparative separation technique in which both the stationary and mobile phases are liquid. In LLC, immiscible of pre-equilibrated biphasic solvent system used as phases. Centrifugal fields to keep one phase stationary, while other pumped through “column.” The different partitioning compounds present an injected mixture between two results elution at time...

Nucleotide sequences of the chloroplast gene rbcL were analyzed to examine relationships among the large, distinctive family Asteraceae and eight putatively closely related families. Phylogenetic analysis of a total of 24 sequences of rbcL identified a lineage consisting of two families, the Goodeniaceae and Calyceraceae, as the sister group to the Asteraceae. In addition, a strongly supported ...

Gonocerus acuteangulatus (Goeze) (Hemiptera: Coreidae) is one of the most harmful hazelnut pests in Europe and Turkey, responsible for affecting seriously crop quality with its feeding activity. Chemical control is very difficult to achieve due to its high mobility and polyphagy; however, it is currently the only available method to reduce effectively damage by bugs. Therefore, a two-year study...
