Inhibition of phytoplankton by allelochemicals released by submerged macrophytes is supposed to be one of the mechanisms that contribute to the stabilisation of clear-water states in shallow lakes. The relevance of this process at ecosystem level, however, is debated because in situ evidence is difficult to achieve. Our literature review indicates that allelopathically active species such as My...

The European Habitats Directive was adopted to halt the rapid loss of biodiversity and has become an important instrument for protecting in Union. Three aquatic plant species protected under have so far been found Lithuania: Aldrovanda vesiculosa, Caldesia parnassifolia, Najas flexilis. Our aim this study evaluate former current distribution status conservation target species. Screening above-m...

Heteropteran communities form a key component of aquatic ecosystems but have not been widely studied compared to other freshwater faunal groups. This research examined the environmental parameters influencing diversity, seasonal distribution and structure Heteroptera assemblages in Mediterranean region Tunisia, northern Africa. Heteropterans were most abundant during spring summer, coinciding w...
