Ebook "Shallow lakes in a changing world: Proceedings of the 5th International Symposium on Shallow Lakes, held at Dalfsen, The Netherlands, 5–9 June 2005" have given us deeper insights into the functioning of food-webs in shallow waters, nutrient dynamics in open water, and in the complexities of interactions in littoral and pelagic regions, and of the sedimentwater interphase. We are now starting to implement the knowledge gained in order to rehabilitate some lakes, if not restore them.

In ebook "Ecology of cyanobacteria II: Their diversity in space and time" cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions.

Ecology Experiments is one volume of the Facts On File Science Experiments set. The goal of this volume is to provide science teachers with 20 original experiments that convey basic principles related to ecology. The experiments in Ecology Experiments are proven classroom activities that broaden understandings of both ecological facts and the nature of science. The content of this volume is based on the three broad areas of the field of ecology: energy flow, recycling of nutrients, and populations.

Human urine from domestic wastewater has been considered as an ideal nutrient source for microalgae cultivation due to the high concentration of nitrogen and phosphorus. Moreover, pollution caused by nutrient (N, P) is difficult to treat and costly. In this study, membrane fouling and nutrient removal was evaluated in a membrane photobioreactor (MPBR) system using urine as substrate and microalgae-bacteria as co-cultures under two light - dark cycles.
