We compiled 414 studies from the literature to test if general relationships exist between chlorophyll concentration, light attenuation, and gross photosynthesis across phytoplankton communities, macrophyte stands, and attached microalgal mats. We also evaluated the upper limit to photosynthesis in the various communities. Along with increasing chlorophyll concentration, the photic zone diminishes from >100 m in sparse phytoplankton communities to centimeters‐meters in macrophyte stands to 
Photoinhibition, UV-B and Algal Photosynthesis
Photoautotrophic algae inhabit a dynamic photic zone that changes both in light quantity and quality. Algae possess adaptive mechanisms to maximize light harvesting and to limit damage by excessive
From thallus to communities: scale effects and photosynthetic performance in macroalgae communities
TLDR
An increase in spatial scale from thallus pieces to communities decreased variation in photosynthetic rates between species, implying that differences between species are much smaller on natural scales than experi- ments on single thalus pieces suggest.
Production in aquatic macrophyte communities: A theoretical and empirical study of the influence of spatial light distribution
TLDR
The results confirm that inefficient distribution of light can account for the low community production rates in aquatic habitats and the depth distribution of form-functional groups of macroalgae with different canopy structure.
Importance of structure and density of macroalgae communities (Fucus serratus) for photosynthetic production and light utilisation
TLDR
It is found that canopy structure had a profound influence on community production and that a non-optimal distribution of light is likely to be the main reason for the lower maximum gross production rates in aquatic than terrestrial plant communities.
Light Limitation within Southern New Zealand Kelp Forest Communities
TLDR
This study suggests that commonly used metrics such as species diversity and density are not as sensitive as direct measures of biomass when detecting the effects of light limitation within macroalgal communities.
Aquatic Plants and Attached Algae
WHOLE‐LAKE FERTILIZATION EFFECTS ON DISTRIBUTION OF PRIMARY PRODUCTION BETWEEN BENTHIC AND PELAGIC HABITATS
TLDR
It is tested the hypothesis that reductions in light associated with increases in phytoplankton could cause compensatory decreases in benthic algal (periphyton) primary production and the increase in whole- lake primary production caused by water column fertilization was greatly overestimated.
Carbon limitation of lake productivity
TLDR
This work shows up to a 5-fold stimulation of phytoplankton productivity and biomass in outdoor mesocosms enriched with DIC, compared to mesocOSms with lower DIC concentrations, to help understand natural variations of lake productivity along gradients in nutrients, DIC and pH.
Effect of water flow on the photosynthesis of three marine macrophytes from a fringing-reef lagoon
TLDR
The results suggest that photosynthetic organisms adapted to coral reef systems, where calm, cloudless days with minimal water turbulence and maximum light penetration are common, have developed efficient CCMs and supports the utility of the fluorescence technique for the analysis of the photosynthesis response to hydrodynamics within the limits imposed by the linear- ity between oxygen-based and fluorescence-based photosynthesis determinations.
Inorganic carbon promotes photosynthesis, growth, and maximum biomass of phytoplankton in eutrophic water bodies
The traditional perception in limnology has been that phytoplankton biomass in lakes is limited by phosphorus, nitrogen, and light, but not by dissolved inorganic carbon (DIC) because CO₂ can be

Nitrogen limitation of photosynthesis and growth: Comparison across aquatic plant communities in a Danish Estuary (Roskilde Fjord)
TLDR
In situ nutrient enrichment experiments in a shallow estuary during mid-summer when irradiance is high, nutrient availability, especially that of N, is low and, therefore, nutrient limitation should be most pronounced, tissue-N, chlorophyll content, maximum photosynthetic rate and growth rate tended to increase following N-enrichment.

TLDR
The existence of a general relationship between tissue thickness and the photosynthetic performance of photosynthesis is suggested, which lends support to the important adaptive role of marine macrophyte tissues in the past.

Light harvesting among photosynthetic organisms
TLDR
Light absorption per unit photosynthetic tissue weight was strongly, linearly related to the chlorophyll a concentration, explaining the lower growth rates and higher light requirements of thick photographsynthetic organisms compared to thin organisms and the dominance of thin photosynthesis organisms in shaded environments.
Minimum light requirements of submerged freshwater macrophytes in laboratory growth experiments.
TLDR
Overall, macrophyte species with different depth distribution or taxonomy did not differ systematically in dark respiration and growth performance in low light in the experiments, but seasonal adaptations in the field, and the possible operation of loss processes (e.g. grazing and detachment), should cause greater light requirements for survival of field populations.
Implications of inorganic carbon utilization: ecology, evolution, and geochemistry
TLDR
The natural occurrence of CO2-concentrating mechanisms is negatively correlated with CO2 enrichment of aquatic habitats from respiration of organic C produced elsewhere and with low temperatures during the growing season, with low external pH, and with rapid water movement over the plant surface.
