Ecological study of chalk streams. Lambourn project. Interim report October 1977 to April 1979 [PDF]
, 1979 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

Water availability and land‐use shape the diversity of Odonata in the Middle East
Insect Conservation and Diversity, EarlyView.Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Ranunculus calcareus and its role in lowland streams [PDF]
, 1979 Ranunculus calcareus , a species of water crowfoot which occurs in clear, nutrient-rich chalk streams, was studied. Seasonal changes in its biomass, its annual production and its fragmentation (leading to downstream movement of the plant) were ...

Effects of vegetation, season and temperature on removal pollutants in experimental floating treatment wetlands [PDF]
, 2010 The research and interest towards the use of constructed floating wetlands for (waste)water treatment is emerging as more treatment opportunities are marked out, and the technique is applied more often. To evaluate the effect of a floating macrophyte mat

Downstream Effects of a Hydroelectric Reservoir on Aquatic Plant Assemblages
The Scientific World Journal, 2002 Macrophytes were studied downstream of the Rophémel hydroelectric dam on the River Rance (Côtes d’Armor Department, western France) to assess the effects of hydroelectric functioning on river macrophyte communities. We studied ten representative sections

An approach to the use of macrophytes for monitoring standing waters [PDF]
, 2001 Under the EC Water Framework Directive (WFD), each Member State is required to devise a comprehensive national monitoring programme for surface waters, incorporating hydromorphological, physico-chemical and biological elements.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]
, 2015 Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.
