Currently, very few studies address the relationship between diversity and biomass/lipid production in primary producer communities for biofuel production. Basic studies on the growth of microalgal communities, however, provide evidence of a positive relationship between diversity and biomass production. Recent studies have also shown that positive diversity–productivity relationships are related to an increase in the efficiency of light use by diverse microalgal communities. Here, we… 
Production stability and biomass quality in microalgal cultivation – Contribution of community dynamics
TLDR
It is proposed that a multispecies community approach can aid sustainability in microalgal cultivation, through complementary use of resources and higher culture stability, while dynamic changes occurred in community composition.
Community Ecology of Algal Biofuels: Complementarity and Trait-Based Approaches
TLDR
This review offers a mechanistic framework for optimizing algal biofuel production while minimizing the negative effects of invasion, infection, and herbivory in open outdoor pond systems.
Algal diversity and traits predict biomass yield and grazing resistance in wastewater cultivation
TLDR
Evidence that polycultures may be less prone to trade-offs between desirable functions for crops (like grazing resistance and growth rate), supporting the concept that diversity can support more functions at once.
Assessing the Potential of Polyculture to Accelerate Algal Biofuel Production
Effects of natural phytoplankton trait diversity on Daphnia spp.
TLDR
It is hypothesized that altered phytoplankton community composition will result in an altered composition of dietary fatty acids, which in turn will affect the intraspecific competition in Daphnia.

The effect of species diversity on lipid production by micro-algal communities
TLDR
The results show that lipid production increased with increasing diversity in both natural and laboratory micro-algal communities, and the incorporation of the ecological advantages of diversity-related resource-use dynamics into algal biomass production may provide a powerful and cost effective way to improve biofuel production.
Ecological optimization of biomass and lipid production by microalgae
TLDR
This study investigates whether diversity may also affect lipid production in microalgae and shows the significant influence of diversity of primary producer communities on their fatty acid composition; especially on essential ω3-PUFA content.
The relative importance of species diversity and functional group diversity on carbon uptake in phytoplankton communities
TLDR
There was a positive correlation between complementarity effects on carbon accrual and light absorbance and hypotheses regarding biodiversity-productivity relationships in phytoplankton communities based on niche separation along spectral light gradients were supported.
Diversity predicts stability and resource use efficiency in natural phytoplankton communities
TLDR
It is shown here that phytoplankton resource use, and thus carbon fixation, is directly linked to the diversity of phytopsized communities, and that the diversity requirement for stable ecosystem functioning scales with the nutrient level (total phosphorus), as evidenced by the opposing effects of diversity and resource level on the variability of both resource use and community composition.
Spectral Niche Complementarity and Carbon Dynamics in Pelagic Ecosystems
TLDR
It is argued that taxon‐specific differential equipment with photosynthetically active pigments provides a biochemical mechanism of resource use complementarity among phototrophic microorganisms, enabling more diverse communities to more completely harvest the light spectrum.
Impacts of plant diversity on biomass production increase through time because of species complementarity
TLDR
It is shown that although productive species do indeed contribute to diversity effects, these contributions are equaled or exceeded by species complementarity, where biomass is augmented by biological processes that involve multiple species.
The coupling of biodiversity and productivity in phytoplankton communities: consequences for biomass stoichiometry.
TLDR
It is shown that biodiversity influences carbon assimilation and nutrient uptake of phytoplankton communities in different ways, resulting in variations of biomass stoichiometry, and data from 46 lake communities support this link.
A mechanistic basis for underyielding in phytoplankton communities.
TLDR
The results indicated that the magnitude of the community biovolume was largely determined by the identity of one species, and functional diversity and resource use complementarity were of minor importance among free-floating phytoplankton, possibly reflecting the lack of spatially heterogeneous resource distribution.
Effects of Algal Diversity on the Production of Biomass in Homogeneous and Heterogeneous Nutrient Environments: A Microcosm Experiment
TLDR
This study suggests that spatial heterogeneity, by itself, is not sufficient to generate strong effects of biodiversity on productivity, and must be coupled with variation in the relative fitness of species across patches in order for spatial niche differentiation to generate complementary resource use.
The functional role of producer diversity in ecosystems.
TLDR
Several new questions must now be addressed if this field is going to evolve into a predictive science that can help conserve and manage ecological processes in ecosystems, including questions about how primary producer diversity influences the efficiency of resource use and biomass production in ecosystems.
