en Limba Engleză Paperback – 28 ian 2012

Continuous cultures, i.e. chemostats with an continuousdilution rate, are model ecosystems for the study of generalregulation principles in plankton communities.Further to an introduction, general continuous culturemethods and especially the characteristics of rotifercontinuousculture systems are presented. Sections onmetabolism and energetics in chemostats, growth models,competition and predator-prey interactions, as well as theapplication of rotifer continuous cultures to ecotoxicologyand their use in aquaculture are included.
