The aim of this study was to compare the selected aquatic plants ability to remove nitrate from wastewater. Excess of these nutrients in water can directly affect human health (methemoglobinaemia) or indirectly through the products of secondary pollution include eutrophication. Negative impact of nutrients excess in surface water often causes the destruction of water ecosystems, and therefore, ...

BACKGROUND Various groups of flowering plants reveal profound ('saltational') changes of their bauplans (architectural rules) as compared with related taxa. These plants are known as morphological misfits that appear as rather large morphological deviations from the norm. Some of them emerged as morphological key innovations (perhaps 'hopeful monsters') that gave rise to new evolutionary lines ...

Utricularia breviscapa C.Wright ex Griseb. belongs to the Lentibulariaceae, a family of carnivorous plants with many aquatic species. We report new record U. in perennial wetland along São João River, Lowland Forest within Atlantic biome. This is first this species from state Rio de Janeiro, southeastern Brazil. differs its congeners South America by presence whorl 3&n...
