In this study, the total phenolic and flavonoid contents antioxidant activities of hexane methanol extracts Cotoneaster transcaucasicus Pojark. fruits in Rosaceae family were investigated. Using Folin-Ciocaltaeu method, amount substances was determined as 50.34 ± 2.70 mg GAE/g extract 38.06 1.32 extract. The flavonoids calculated 52.01 3.78 QE/g 60.54 6.82 extract, using aluminum nitrate method...

Navigating on the wing in complete darkness is a challenging task for echolocating bats. It requires the detailed analysis of spatial and temporal information gained through echolocation. Thus neural encoding of spatiotemporal echo information is a major function in the bat auditory system. In this study we presented echoes in virtual acoustic space and used a reverse-correlation technique to i...

We present a revision of Glebionis coronaria in the Mediterranean area based on: a) micro-morphology of the disc floret cypselas observed with a high-resolution confocal microscopy; b) measurements of the disc cypsela with a stereoscopic microscope - duly scaled; c) its distribution in several bioclimatic belts; d) field observations; e) comparisons of herbarium samples. Because of this study, ...
