ABSTRACT
Aster-like nanoparticles (ALNs) are femtoentities, recently discovered in different aquatic environments, whose intrinsic nature and ecological features remain to be determined. In this study, we investigate the in situ temporal dynamics of ALNs during 1 year in 3 different lakes, in relation to the physico-chemical and biological environment. ALN abundances in investigated lakes showed a marked seasonal dynamic (from no detectable to 4.28 ± 0.75 × 106 ALNs mL-1), with characteristic peaks in spring. We recorded a correlation between ALNs and some prokaryotic phyla suggesting a broad and non-specific relationship. From their seasonal dynamics and potential link with prokaryotes, we conclude that ALNs represent an important ecological actor in the functioning of aquatic ecosystems.
