Comparison of methods for measuring production by the submersed macrophyte , Potamogeton perfoliatus L
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...
متن کاملModelling the clonal growth of the rhizomatous macrophyte Potamogeton perfoliatus
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...
متن کاملSpatio-temporal dynamics and plasticity of clonal architecture in Potamogeton perfoliatus
Aboveand below-ground clonal growth architecture was compared for two neighbouring patches of Potamogeton perfoliatus L. in Lake Constance, representing typical sparse and dense growth types. A detailed map of individual ramets and their corresponding rhizome network was produced and the seasonal development of ramet sprouting and rhizome growth was reconstructed. Rhizomes extended at rates ran...
متن کاملDNA barcoding reveals a new record of Potamogeton distinctus (Potamogetonaceae) and its natural hybrids, Potamogeton distinctus × Potamogeton nodosus and Potamogeton distinctus × Potamogeton wrightii (Potamogeton ×malainoides) from Myanmar
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...
متن کاملPlants accumulating heavy metals in the Danube River wetlands
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...
