Hydrocotyle ranunculoides L.f. is reported in this paper to be present at only 29 sites in the south east of England and in South Wales, in a wide range of water body types, which are typically slow-flowing and eutrophic. The current infestation is l

Moderation of aquatic plant growth by changing the primary growth control factor, light, is an economically viable and ecologically acceptable technique for many lake and stream habitats. In open unshaded waters, great potential exists for plant grow

An apparatus to measure the rates of respiration and photosynthesis of aquatic plants in water at velocities of up to 200 mm s−1 in a closed water-flow system with partial recirculation, is described. The temperature, the light regime and the conce
