Data on the Distribution and Ecology of Pistia stratiotes L. (Araceae) in Hungary
Free‐floating macrophyte invasions pose an increasing threat to lowland freshwater systems in Central Europe, particularly in thermally influenced canal networks. This study provides the first detailed assessment of the distribution, habitat conditions, dispersal, and reproduction of Pistia stratiotes along the Élővíz Canal in southeastern Hungary ...

Catchment Influences on Carbon Stable Isotope Variation in Trout; Might It Be Methane?
Trout stable carbon isotope values vary significantly and appear to relate to catchment characteristics. Low carbon stable isotope values are linked to catchments with low drainage soil and high cover of pasture land use. This is likely to be linked to high levels of methane‐derived carbon entering the stream food web.

Abstract Ecosystems around the world have experienced shifts in community state as a result of anthropogenic activities that alter important ecological feedbacks. On coral reefs, transitions to a state where fleshy macroalgae are a major space holder have often been associated with the loss of top‐down control, which frequently has been attributed to ...

Evaluation of macrophyte control in 38 Florida lakes using triploid grass carp [PDF]
Florida’s large number of shallow lakes, warm climate and long growing season have contributed to the development of excessive growths of aquatic macrophytes that have seriously interfered with many water use activities.

In the subhumid, wetland‐rich, geologically heterogeneous Boreal Plains region of Canada, we found several controls on stream DOC concentration ([DOC]) and DOM composition: An increase in [DOC] and aromaticity as temperature increases throughout the summer, with temperature trend prevailing over the influence of discharge.

Ecological study of chalk and limestone stream. Annual report October 1975 to September 1976 [PDF]
Few detailed studies have been made on the ecology of the chalk streams. A complex community of plants and animals is present and much more information is required to achieve an understanding of the requirements and interactions of all the species. It is
