Attached Algae: The Cryptic Base of Inverted Trophic Pyramids in Freshwaters (2017, background): “Algae in the lineage arising from the second incorporation of endosymbionts synthesize the longer chain EFAs de novo (Falkowski et al. 2004).”
Are tropical streams really different? (2009, background): “These studies highlight the importance of distinguishing between assimilated and consumed food through stable isotopes and gut content analyses to obtain a reliable picture of the stream food web (Mantel et al. 2004, Lau et al. 2009a).”
High-quality algae attached to leaf litter boost invertebrate shredder growth (2016, background): “Algae are much higher quality food than allochthonous leaf litter for stream invertebrates because they have a higher content of polyunsaturated fatty acids (PUFAs), in particular ω3 PUFAs (Torres-Ruiz et al. 2007, Lau et al. 2009).”
How important are terrestrial organic carbon inputs for secondary production in freshwater ecosystems (2017, background): “Stream studies suggest that even when allochthonous inputs greatly dominate invertebrate and fish production is very preferentially supported by algal basal resources (Brito et al., 2006; Bunn et al., 2003; Lau et al., 2009a; Mayer & Likens, 1987).”
