In our second model, we show that intraspecific trait variance is competitively antifragile under a fluctuating optimal environment, mediated by eco-evolutionary dynamics. However, biomass, productivity, and resilience never benefit from fluctuations in this model. (4/4)

In our first model, we examine under what conditions phytoplankton annual productivity is antifragile with respect to temperature and find that this is true at the community, but not species, level, and under top-down, but not bottom-up, control. (3/4)

We find that even in two highly symmetric models, outcomes are highly idiosyncratic with more available resources sometimes leading to lower evolved consumer diversity for the same trade-off shape. (3/3)

We develop some new tech to deal with high-dimensional resource space, where consumers’ uptake abilities for different resources are traded off against each other. We then assemble communities for different trade-off shapes and dimensionalities, to find when diverse communities evolve. (2/3)

When parameterized with micro-scaling exponents our model predicts macro-scaling exponents between zooplankton biomass and phytoplankton biomass, and between phytoplankton mean body mass and biomass that agree remarkably well with observed macro scalings. 4/5

We propagate estimates of micro-scaling exponents and their uncertainty through our model predictions into how state variables scale with nutrient enrichment (A). Estimates of micro-scaling exponents from the literature (B). Model-predicted scalings with enrichment (C, D). 3/5

At the individual level, micro scalings relating to cell size determine many traits (F–I). These scaling relationships constrain eco-evolutionary dynamics (E), from which macro-level scaling relationships emerge across environmental gradients (A–D). 2/5
