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.

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)

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)

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

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
