There may be no other group of plants with such highly developed morphological and physiological adaptations to extreme conditions. They are a rich source of steroids, triterpenes, saponins, flavonoids, alkaloids and tannins. The Pondicherry region in South India has no forest, but has scattered patches of...

Ecological status of waterfowl habitat on the Gemenc floodplain area in Hungary
Hydrological, chemical and biological methods were applied to investigate the ecological status of the Gemenc floodplain area. The examined wetland was generally poor in planktonic organisms, however benthonic eutrophication was evident. 81 plant species and 17 associations were proved to appear during the examined years. Formation of vegetation was influenced by water-level. The hydrological regime changed...
