The role of two submerged macrophyte species (Ceratophyllum demersum and Potamogeton pectinatus) as biological factor affecting concentrations of P and chlorophyll a concentrations was tested under laboratory conditions. In general, after four weeks exposition, the significant reduction of TP, P-PO4 and chlorophyll a was observed in all experimental variants (aquaria with P. pectinatus, C. deme...

Emergent or submergent macrophytes can enhance the survival of Anopheles larvae by providing favorable microhabitat and refuge from predation. The relationships among the amount of aquatic macrophyte cover, the density of Gambusia affinis, and survivorship of Anopheles freeborni larvae were tested experimentally. Larval survivorship was positively related to amount of plant cover and negatively...

As many as 963 herbarium sheets featuring 76 aquatic plant taxa from the ZA collection were digitised and published online through Virtual Herbarium. Aquatic plants have been collected over a period of 176 years, with three peaks (second decade 20th century, in 1940s 1950s, current decade). Most specimens Croatia smaller number neighbouring geographically close countries. The importance is expr...
