1. The perfoliate pondweed Potamogeton perfoliatus L. constitutes large monospecific macrophyte patches in many Central European lakes. Correlative evidence from the field suggests that P. perfoliatus is under an increasing grazing pressure during its short vegetation period fromMay to September due to seasonal outbreaks of the aquatic moth Acentria ephemerella Denis & Schiffermüller. We used a...

Warming and higher nitrogen loading induced by increasing precipitation are expected scenarios in north temperate regions as consequence of global climate change, with potential effects on the functional traits submerged macrophytes periphyton. Using an experimental heating facility we investigated responses three-week growth two (Potamogeton crispus Linn. Elodea canadensis Michx.), periphyton ...

Macrophytes play important roles in shallow aquatic ecosystems. Stable isotope signatures of macrophytes indicate the environmental conditions and macrophyte contributions to food webs. However, have been studied less than other organisms. We determined stable C N 10 plant species from Poyang Lake wetland (Wucheng, Yongxiu County) Nanji (Nanjishan, Xinjian Jiangxi Province, which are Chinese na...

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 ...
