Although algae are discussed as a potential food source for predators, little is known about the structure of algae coenoses in pitchers of <jats:italic>S. purpurea<\/jats:italic>. This study aims to elucidate temporal shifts in the algae community structure in pitchers of an allochthonous population of <jats:italic>S. purpurea<\/jats:italic> in Saxony, Germany. A total of 78 algae taxa was found in the pitchers. Mean algae abundances in new and old pitchers were similar (2.6 \u00d7 10<jats:sup>5<\/jats:sup> and 2.3 \u00d7 10<jats:sup>5<\/jats:sup> algae ml<jats:sup>\u20101<\/jats:sup>, respectively). Taxa from the orders Chlamydomonadales, Chlorococcales, and Ochromonadales were the primary colonisers. With increasing age of the pitchers the filamentous green algae from the order Klebsormidiales became more abundant. In contrast, pennate diatoms dominated the algae coenoses in the fen. Algae community structure in vase\u2010shaped 50 ml Greiner tubes was similar to those of natural pitchers. Differences in the temporal patterns of algae coenoses in individual pitchers suggested a colonisation of the pitchers by algae via trapped insects, air and rain water rather than via the surrounding fen. Biomass of algae approximated 0.3 mg C ml<jats:sup>\u20101<\/jats:sup>, which corresponds to 82.8 % of the living biomass (bacteria, heterotrophic nanoflagellates, algae, protozoans and rotifers). Rotifers were abundant in new pitchers; nematodes and mites were seldom found in all pitchers. A similar qualitative and quantitative composition of the aquatic biocoenoses was observed in pitchers of another allochthonous <jats:italic>S. purpurea<\/jats:italic> population growing in Blekinge, Sweden. Biomass of algae represented nearly one quarter of the total organic matter content in the pitchers. Thus, nitrogen and phosphorus compounds present in the algae biomass might be used by the carnivorous <jats:italic>S. purpurea<\/jats:italic> plant as additional food source in allochthonous populations in Europe lacking top predators.<\/jats:p>","DOI":"10.1055\/s-2006-924474","type":"journal-article","created":{"date-parts":[[2007,1,3]],"date-time":"2007-01-03T19:01:39Z","timestamp":1167850899000},"page":"849-860","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Development of Microalgae Communities in the Phytotelmata of Allochthonous Populations of <i>Sarracenia purpurea<\/i> (Sarraceniaceae)"],"prefix":"10.1111","volume":"8","author":[{"given":"C.","family":"Geb\u00fchr","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Pohlon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
