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. www.journals.uchicago.edu/doi/10.1086/...

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...

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....

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) www.sciencedirect.com/science/arti...

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…

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...

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.

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

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.
