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 propose that ‘antifragility’, coined by Nassim Taleb, is a great high-level concept for ecologists of all kinds for parsing and communicating the effects of environmental variability. An antifragile property benefits from variability. We explore its use in two mathematical models. (2/4)

Does availability of juvenile refuge affect size structure of adults? Uszko et al. show that size of streams used as nurseries impacts growth and size structure of lake trout by controlling the strength of cannibalistic mortality and resource competition.

Evolution Under Competition Increases Population Production by Reducing the Density‐Dependence of Net Energy Fluxes and Growth Using experimental evolution, we determined the impact of intra- versus interspecific competition on three marine phytoplankton species. We found that the species achieved the same evolutionary outco....

Happy to share our new paper! We tested how species evolve in response to #competition. We tracked the evolution of 3 #phytoplankton species, evolved alone or together. Our main finding is that #density-dependence weakens through #evolution to increase population production. doi.org/10.1002/ece3...

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)

The effects of trade-off shape and dimensionality on eco-evolutionary dynamics in resource competition Organisms invariably experience trade-offs in their capacities for interacting with their environments. In resource competition, this often means that…

No more competing consumers than there are resources can coexist in equilibrium, but have you ever wondered how many consumers actually evolve as resource diversity increases? In our new paper, @chrisklausmeier.bsky.social and I investigate. (1/3)

Dispersal stabilizes coupled ecological and evolutionary dynamics in a host-parasitoid system Experiments and simulations show that dispersal maintains host genetic diversity and promotes host-parasitoid coexistence.

Excited to share our new paper out in Science! We combined simulations, experiments, and field data to show how dispersal simultaneously stabilizes species and genetic diversity, which results in persistent eco-evo dynamics. doi.org/10.1126/scie...

Our work ties scalings at different levels of organization to one another and to ecological and evolutionary mechanisms. As these scalings have mostly been studied in isolation, our work points the way towards integrated study for testing the interrelation of scalings. 5/5

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

Eco-evolutionary emergence of macroecological scaling in plankton communities Eco-evolutionary dynamics informed by allometric scaling can predict large-scale patterns across planktonic food webs.

Delighted to announce our new paper in Science. @chrisklausmeier.bsky.social, @elenalitchman.bsky.social, and I show how power-law scaling at the micro (individual) level is translated by eco-evolutionary dynamics into power-law scaling at the macro (food-web) level. 1/5
