Did all of science peak in 2021 and is yet to recover from the pandemic? Jeremy Fox has a new post about this. I know my own productivity didn’t go up (altho citations did!) even in the 1st year of covid (existential fights for tenure can do that) & I’ve continued to struggle with motivation since.
Science (all of it) peaked in 2021
An ecologist friend* noticed that the annual number of times he’s been cited grew throughout his career up until 2021, when it peaked. It then declined for a couple of years straight. Then it…

I'm excited to share that our preprint is now available on bioRxiv! Our study challenges the widespread use of molecular genetic diversity as a predictor adaptive potential, with important implications for how genetic data is used to inform conservation decisions.

Nucleotide diversity is a poor predictor of short-term adaptive potential
A capacity to adapt is essential for a population to avoid extinction in a changing world and is recognised as a global conservation priority. Adaptation requires additive (heritable) genetic variatio...

Excited to share my first first-author paper from my master’s work at @carleton.ca , with @andrew-m-simons.bsky.social and Myron Smith!

We explored how constraints on adaptation can aid the persistence of bet-hedging traits in the short term.

Avoiding dead ends: the experimental evolution of constraint as adaptation to environmental variation
Abstract. Environmental unpredictability can result in the evolution of bet-hedging traits, which maximize long-term fitness but are, by definition, subopt
