Grubisic, M., Singer, G., Bruno, M. C., van Grunsven, R. H. A., Manfrin, A., Monaghan, M. T., et al. (2018). A pigment composition analysis reveals community changes in pre-established stream periphyton under low-level artificial light at night. Limnologica, 69, 55–58.
Abstract: Freshwaters are increasingly exposed to artificial light at night (ALAN), yet the consequences for aquatic primary producers remain largely unknown. We used stream-side flumes to expose three-week-old periphyton to LED light. Pigment composition was used to infer community changes in LED-lit and control periphyton before and after three weeks of treatment. The proportion of diatoms/chrysophytes decreased (14%) and cyanobacteria increased (17%) in lit periphyton in spring. This may reduce periphyton nutritional quality in artificially-lit waters.
