title: Ecological impacts of photosynthetic light harvesting in changing aquatic environments: A systematic literature map

description: Underwater light is spatially as well as temporally variable and directly
 affects phytoplankton growth and competition. Here we systematically
 (following the guidelines of PRISMA-EcoEvo) searched and screened the
 published literature resulting in 640 individual articles. We mapped the
 conducted research for the objectives of (1) phytoplankton fundamental
 responses to light, (2) effects of light on the competition between
 phytoplankton species and (3) effects of climate change induced changes in
 the light availability in aquatic ecosystems. Among the fundamental
 responses of phytoplankton to light, the effects of light intensity
 (quantity, as measure of total photon or energy flux) were investigated in
 most identified studies. The effects of the light spectrum (quality) that
 via species-specific light absorbance result in direct consequences on
 species competition emerged more recently. Complexity in competition
 arises due to variability and fluctuations in light which effects are
 sparsely investigated on community level. Predictions regarding future
 climate change scenarios included changes in in stratification and mixing,
 lake and coastal ocean darkening, UV radiation, ice melting as well as
 light pollution which affect the underwater light-climate. Generalization
 of consequences is difficult due to a high variability, interactions of
 consequences as well as a lack in sustained timeseries and holistic
 approaches. Nevertheless, our systematic literature map, and the
 identified articles within, provide a comprehensive overview and shall
 guide prospective research.
description: Literature was collected according to the PRISMA-EcoEvo
 (O'Dea et al., 2021) guidelines according to three objectives (i.e.
 research question). Search was conducted in Web of Science on 15th of June 2021 with
 separate searches per objective. Suitable articles were identified by
 "topic". Results
 were imported to EndNote (Clarivate). Within the respective objective different topics
 of interest were identified and quantified (number of articles, and median
 year of publication per topic).

 Endnote into Microsoft Excel.<br>Within the Excel file
 ("Literature_Hintz_et_al_SystematicMap.xlsx") all references are
 sorted sheetwise according to their objective and topic.
 <br>Due to clarity, not all reference information
 (as in Endnote) is presented in the Excel file. E.g., it does not contain
 abstracts, accession numbers etc. Nevertheless a identfication of the
 literation is given by: authors, year, title, journal, volume, issue,
