πŸ“’ NEW GENOME ALERT

In #G3journal, @owengosborne.bsky.social et al. present a high-quality genome assembly and high-density linkage map of Silene uniflora, a hermaphroditic species that is emerging as an important model for rapid adaptation to human disturbances. buff.ly/dnhnUDF

πŸŽ‰ Exciting milestone … my first PhD paper has been accepted in the Journal of Experimental Biology! πŸ₯³
Not all winter warming is equal: steady, mild winters increase activity and can cause molecular damage, but short, warm spells have little effect on wall lizards 🦎

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

First post! New paper in Infection & Immunity.

We asked: what do #probiotics do to microbiome & immune system?

They do more to microbiome than immune system, but depended on probiotic & effects fleeting with cocktail impacts different than individual strains.

Eastern newt (Notophthalmus viridescens)

We’re recruiting for a #PhD opportunity funded by NERC Envision DTP, investigating the impact of climate change on chytrid disease dynamics in Appalachian salamanders.

Our new paper shows that plasticity that has evolved to deal with one stressful situation, can help plants to adapt rapidly to new stressful situations. doi.org/10.1073/pnas... @meebangor.bsky.social @rbgkew.bsky.social @ukri.org @pnas.org

Sexual selection promotes reproductive isolation in barn swallows Despite the well-known effects of sexual selection on phenotypes, links between this evolutionary process and reproductive isolation, genomic divergence, and speciation have been difficult to establis...

In 2013 Liz Scordato & I did a ~6k mi transect of Russia. It was *part* of a larger study of how divergence in traits used in mate choice & competition affects the formation of new species. Today, we have a paper in Science, led by Drew Schield & Becca Safran πŸ§ͺπŸͺΆπŸ¦š

Code-sharing policies are associated with increased reproducibility potential of ecological findings

In 2020, we showed that studies published in ecological journals WITH a code-sharing policy showed a 21% reproducibility potential at max (Culina et al 2020, @plosbiology.bsky.social)

We've now investigated journals WITHOUT a code-sharing policy. The results are worrying.
