Abstract:Carbon from aquatic plants and periphyton in littoral zones subsidize food webs. Field work was carried out in two different lake types in the Colombian Amazon: a várzea (Yahuarcaca) and an igapó (Pacatúa). Plants in the littoral zone of várzea Lake had higher photosynthetic biomass compared to the plants of the littoral zone of igapó, but differences in root biomass were not significant. The two littoral zones contained a relatively high species richness and diversity (Shannon-Wiener Index) of organisms assoc… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
