Macrophytes play a crucial role in the functioning of lake ecosystems. Until now most macrophyte models neglected the fact that the majority of macrophyte species expand clonally during the growing season. Inclusion of a detailed description of clonal growth in models can facilitate our understanding of space occupation and patch expansion and predict future macrophyte development. “CLOMO” is a...

For the first time, component composition of low-molecular-weight metabolome perfoliate pondweed (Potamogeton perfoliatus L., family Potamogetonaceae), which grows in Astrakhan region (lower zone Volga river delta), has been investigated. Low molecular weight organic compounds (LMWOCs) essential oil were obtained from dried plants by steam hydrodistillation using Clevenger apparatus. The qualit...

Abstract This study aims to determine some physical and chemical factors their impact on the abundance distribution of submersible aquatic plants for four selected stations in southern marshes, two Eastern Hammar marshes (Al-Burga Al-Sada) Al-Chebiyesh (Abu-Sobat Al-Baghdadia). Water plant samples were collected seasonally during year 2018. The water temperature, electrical conductivity, depth ...

Six conventional methods for measuring primary production of submersed vascular plants were compared to test for previously suggested inherent shortcomings in the O,-exchange techniques. Production was measured for experimental populations of Potamogeton perfoliatus L., from upper Chesapeake Bay in five comparative studies, each including an O,-exchange method. All techniques tested (14C incorp...
