Due to its unique environmental and geological traits, Poyang Lake Nature Reserve in China was chosen for studying the characteristics of a Potamogeton community. The results were as follows: (1) two emergent and four submerged macrophytes were identified in the Potamogeton malaianus community, in which four growth forms (herbids, magnopotamids, parvopotamids, vallisneriids) were classified. Po...

The perfoliate pondweed Potamogeton perfoliatus constitutes large mono-specific macrophyte patches in many Central European lakes. Correlative evidence from the field suggests that Potamogeton is under an increasing grazing pressure during its short vegetation period from May to September due to seasonal outbreaks of the aquatic moth Acentria ephemerella. We used a mesocosm experiment to determ...

BACKGROUND We present herein our results regarding the accumulation of four heavy metals (copper, cadmium, lead, and zinc) in four aquatic species plants (Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton lucens, Potamogeton perfoliatus) collected from the Danube River, South-Western part of Romania and their possible use as indicators of aquatic ecosystems pollution with heavy metals...

Indo-China floristic region is among the 34 richest floristic regions of the world, and its plant diversity is still under investigation. Here we report a new record of an aquatic plant, Potamogetondistinctus, from Myanmar, a part of the region, that is detected by means of DNA barcoding method. The molecular method further identified the other specimens as hybrids of Potamogeton: one is Potamo...

Potamogeton is one of the most difficult groups to clarify in aquatic plants, which has an extensive range of interspecific morphological and ecological diversity. Internal transcribed spacer (ITS) is prevalent for phylogenetic analysis in plants. However, most researches demonstrate that ITS has a high percentage of homoplasy in phylogenetic datasets. In this study, eighteen materials were col...

Aquatic plants anchored in streams are under pressure from various constraints linked to the water flow and display strategies to prevent their damage or destruction. We assume that the responses of aquatic plants to fast-water flow are a manifestation of a trade-off consisting in either maximizing the resistance to damage (tolerance strategy) in minimizing the hydrodynamic forces (avoidance st...

To investigate the effects of different habitats and plant growth status on abundance, biomass and community structure of epiphytic microbes, Potamogeton malaianus Miq. at two different habitats (Gonghu Bay and East Taihu) in Lake Taihu were collected in June, August and November (corresponding to the period of development of submerged macrophytes). The relative abundance of major epiphytic alg...
