Take a look at our new paper on how the evolution of seasonal plasticity associated with climate change can vary between life stages, tested by recreating experiments from 35 years ago on Speckled Wood butterflies: doi.org/10.1111/ele.14280 @Ecology_Letters
Evolution of butterfly seasonal plasticity driven by climate change varies across life stages

Evolution of butterfly seasonal plasticity driven by climate change varies across life stages

Phenology often depends on multiple plastic decisions made during different life stages and seasons, but these responses may evolve separately in response to climate change. We replicated common...

I only just realized that my Helsinki email address in the job posting is incorrect. If you have questions, please contact me at the Bremen email address. (In my defense, this advertisement was first written before I actually had a Helsinki email.)

It's great to see some high-quality writing about the importance of time for phenotypic plasticity. This is a really important feature of plasticity that gets almost no attention.

Just out in @Trends_Ecol_Evo: we need to go beyond reaction norms alone, integrating the temporal dynamics of phenotypic plasticity! Amazing discussions and work these last 2 years to end up with this! 🤩

For my own research on phenotypic mismatches, I usually deal with plasticity that can only happen during a single developmental transition (e.g., diapause that only begins at pupation). This is yet a different kind of temporal dynamic.

Temporal dynamics are everywhere for plasticity. This paper will help me write about that so much more clearly and has given me plenty of new ideas.

The project will work with local schools to test whether evolutionary changes in the life history and plasticity of urban butterflies are adaptive. It will also explore the potential of classroom research projects and urban evolution as teaching tools.

Because the PhD researcher will work directly with local school classes, this position does require the ability to speak Finnish.

On the train to Prague for #BoB2023. First time for international rail travel and so far it's really nice! Super excited to spend a week nerding out about butterflies.

The difference could be tied to the different phenology of these populations (one has one generation per year, the other two), but that will take further research to understand!

As a side note, this was my first attempt at a preregistered study (osf.io/6xq4r) and possibly among the first published preregistered empirical studies in our field. But, unsurprisingly, not everything went according to plan, and we discuss that in the paper.
