Some butterflies adapted to have second ‘heads’ that confuse predators A new evolutionary analysis of butterflies finds “false heads” arose from the coalescence of multiple traits

Our false head work is out! By analysing ~1000 #butterflies, we found many traits at posterior end of hindwings evolved correlatedly, likely forming a trait complex w/adaptive function to dupe predators into thinking these traits together are actual head!!

Fitting a generalized mixed model with a gamma distribution log link and random slopes to reaction time data to arrive at precisely the same point estimate as the authors did by simply averaging and conducting a t-test:

Why you can't have it all in experiments in ecology The trade-off between realism and mechanistic resolution, and why this is important.

My new substack newsletter explains the fundamental trade-off in experiments in ecology and environmental sciences: you can either have mechanistic resolution or realism, but not both in the same experiment.

Why science is hard, or at least one reason why it is difficult And how to cope (at least with this one particular aspect)

This week’s newsletter talks about why science is so hard, or at least one reason….this was something I struggled with at the beginning of my PhD.

I wonder if other people feel or felt the same way? Let me know….
