Sian Henley and I have just had a NERC grant funded, looking at variation in Souther Ocean diatom traits under fluctuating light regimes. If you are a fearless experimentalist interested in working with us as a postdoc on this 3 year project, come chat with me at Ocean Sciences in Glasgow next week!

A study in subarctic Iceland finds microbes hoard nitrogen under higher temperatures, with effects on the whole ecosystem.

As Some Soils Warm, Microbes Stockpile Essential Nutrients - Eos
A study in Iceland found that microbes are hoarding more nitrogen for themselves, altering nutrient cycling and leaving less for plants.

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. www.biorxiv.org/content/10.6...

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. royalsocietypublishing.org/rspb/article...

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
