Two environmental 18S rDNA  surveys were conducted on the 0.6 - 5 µm planktonic  fraction of the oligotrophic Lake Pavin, at the  begining and at the end of the thermal  stratification period, when unidentified small HF  develop. Phyogenetic analysis of the retrieved  sequences highlighted original results. (i)  Recovered sequences differed from microscopic  diversity studies. (ii) The revealed diversity  within HF was higher than the diversity previously  detected using traditional methods. (iii) Most of  the detected HF species were not bacterivorous, but  saprotrophs and (or) parasites. Finally, a  quantitative PCR assay was developped in order to  quantify chytrids zoospores (Fungi), i.e.  phytoplanktonic parasites which actually are totaly  ignored in the dynamic of lacustrin systems.  Overall, the main findings indicate that we need to  revise the functional role of HF, by including  saprotrophs and parasites in our conception of   matter and energy flows in aquatic microbial food  webs, and the related biogeochemical cycles as well.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786131516054\"\u003e\u003ch3\u003eLes flagellés hétérotrophes codent pour de nouvelles fonctions putatives dans les écosystèmes lacustres (Lac Pavin, Massif-Central, France)\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786131516054","offer_id":40148967325789,"sku":"9786131516054","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e63f7cad-d91d-41ad-bcdc-ba712015267f.jpg?v=1777012162","url":"https:\/\/shop.autorenwelt.de\/products\/molecular-diversity-of-heterotrophic-flagellates-in-aquatic-ecosystems-von-telesphore-sime-ngando-und-emilie-lefevre","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
