WebCryptophyte algae are globally distributed photosynthetic flagellates found in freshwater, estuarine, and neritic ecosystems. While cryptophytes can be highly abundant and are consumed by a wide variety of protistan predators, few studies have sought to quantify in situ grazing rates on their populations. Here we show that autumnal grazing rates on in … WebIntroduction. The cryptophyte algae (= cryptomonads) are an evolutionarily distinct and ecologically important unicellular eukaryotic lineage inhabiting marine, brackish water, and freshwater environments (Graham and Wilcox 2000; Shalchian-Tabrizi et al. 2008).Cryptophytes are mostly photosynthetic with plastids that contain chlorophyll-a and …
