📄 New preprint! We used Arabidopsis to test whether plant–plant communication in response to insect herbivory was conserved in wild populations with dramatically different environments, genetics, and life-history traits; it is indeed! [1/2]

New paper out today in Ecology Letters! We use Modern Coexistence Theory and Metabolic Theory to get general predictions for the effect of temperature on competition. Led by brilliant postdoc @kaleighedavis.bsky.social and @joeybernhardt.bsky.social, with Po-Ju Ke, Patrick Thompson and Mary O'Connor

General Predictions for the Effects of Warming on Competition

We combined two major theories in ecology to investigate whether warming may have general effects on competition for shared resources. We found that species' niche and fitness differences both decrea...

Excited to share a new article from the lab & wonderful co-authors. We argue that habitat fragmentation research needs to be recalibrated to focus on changes over time. We hope that doing so will advance understanding, isolate attribution, and diminish heated debate. www.cell.com/trends/ecolo...

Resurrecting habitat fragmentation as a process over time

Habitat loss and fragmentation occur over time. Despite this truism, understanding the effects of habitat fragmentation has, in recent years, predominantly focused on interpreting snapshots of current...

Out now! Ecological #ResponseDiversity research priorities @nordicoikos.bsky.social 🌍🧪 Key findings: Ecologists don't agree (I could stop there) on definitions (& there...) of #ResponseDiversity scales & dimensions but see conceptual value Our network must diversify. Join us! doi.org/10.1002/oik....

Happy to share the final version of @oliviamghosh.bsky.social's paper on inferring low dimensional phenotype-fitness maps from high-throughput fitness measurements across environments. Fun collaboration with @oliviamghosh.bsky.social, @grantkinsler.bsky.social, & @petrovadmitri.bsky.social

Predicting the effect of a #mutation on #fitness is hard. @oliviamghosh.bsky.social @petrovadmitri.bsky.social &co use fitness effects of adaptive yeast mutants to show that underlying genotype-phenotype-fitness maps are low-dimensional but context-dependent @plosbiology.org 🧪 plos.io/4dLy2Ez

Two models for the nature of pleiotropy in adaptation. Left: Schematic of the environmental structure in this study. Environments can be mapped onto a multidimensional environment space characterized by chemical and physical compositions. The large green circle represents an environment where adaptive mutants evolved, and the large pink circle is a distant environment. Around each base, a set of identical environmental perturbations (arrows) is applied, generating clusters of similar environments around distinct base environments. Top right: Schematic of fitnotype map for adaptive mutants near their home base environment. By measuring fitness in each of the green environments, one can infer how many fitnotypes matter for this set of mutants in their home environment. Here, only four of the possible 8 fitnotypes matter. Bottom right: When the mutants are moved to the distant base environment, and their fitness is measured in all pink environments (base and perturbations), there are two possibilities. Either more fitnotypes become important and the space appears higher-dimensional (left, pleiotropic expansion), or the set of fitnotypes that matters remains low-dimensional, but shifts (right, pleiotropic shift).

I have written my first R-package for feeding experiments! BayesFR allows fitting functional responses by providing dynamical prediction models for use in #brms. Includes models for classical type 2 and type 3 responses, and also prey mortality or predator interference (more to come) #Rstats (1/3)
