Different areas of the city may be permanently or temporarily dominated by certain factor. Vegetation component urban landscapes, which are natural and artificial objects various functional purposes. ecological functions green spaces include: environmen...

This study investigates stable carbon and hydrogen isotope compositions of leaf wax n-alkanes from 3 angiosperm and 2 conifer species from a semi-desert natural environment. The dC and dD n-C27 alkane data show a clear distinction between Populus tremuloides/Syringa vulgaris ( 31.9 to 32.7‰ and 168 to 186‰, respectively) and Pinus sylvestris/ Picea pungens ( 28.8 to 30.6‰ and 190 to 212‰) throu...

PREMISE OF THE STUDY Investigations of inflorescence architecture offer insight into the evolution of an astounding array of reproductive shoot systems in the angiosperms, as well as the potential to genetically manipulate these branching patterns to improve crop yield and enhance the aesthetics of horticultural species. The diversity of inflorescences in the economically important family Oleac...
