Improved gene tree inference from removing alignment errors both from focal genes and when training substitution models Multiple Sequence Alignment (MSA) is a key step in phylogenetic analysis, and is prone to error. Unfortunately, algorithms that remove likely alignment errors from MSAs sometimes also remove informati...

Sequence alignments are notoriously prone to error. Our latest preprint offers a new tool for filtering errors out, assesses it and other filtering tools, and recommends new best practice. www.biorxiv.org/content/10.6... @phylowheeler.bsky.social 1/10

Jardin en bazar en février ? Les spécialistes vous demandent surtout de ne plus y toucher, voici pourquoi ... si votre jardin ressemble à un champ de bataille en ce moment, vous avez officiellement le droit… de ne rien toucher. Pour le reste de février, les spécialistes de la faune recommandent au contraire de laisser son jardin en désordre en février, car ce fouillis devient un véritable kit de survie pour les animaux.   La rédaction Vie Pratique 14 Fév 2026   "... Pour l’expert en jardinage Benedict Vanheems, mieux vaut freiner sur le nettoyage : "Laissez les bordures ornementales non coupées aussi longtemps que vous le pouvez. De nombreux insectes bénéfiques se réfugient parmi les tiges de plantes anciennes et les têtes de graines, ce qui aidera également à nourrir les oiseaux. Il n'est pas vraiment nécessaire de tailler avant le début du printemps, lorsque la nouvelle croissance commence à percer. Si vous avez besoin de propreté, vous pouvez toujours laisser juste une zone non coupée", a-t-il expliqué au média britannique Express. Les herbes un peu longues gardent aussi des débris de graines que les merles et pinsons viennent fouiller.   Les feuilles mortes laissées sous les haies ou au pied des arbres forment une couverture qui protège le sol du froid, abrite insectes et vers, et finit par nourrir la terre."

I love these striking asymmetries in plant-animal interactions. Here you have one of the most widespread European plants (Erodium cicutarium) visited by Andrena (Avandrena) baldocki, a bee species known only from the southernmost Iberian Peninsula and whose females gather exclusively Erodium pollen

A figure depicting continental drift from when Gondwana existed to present day, with continents and countries colored according to the ratite species that occur or occurred on them. Next to that is a cartoon of a phylogeny that we would expect support for if continental drift explained patterns of species occurrence and relatedness. And next to that is a cartoon of the phylogeny supported by the genetic data presented in this paper, which demonstrates that closely related species must have traveled great distances after Gondwana broke up, after which flightlessness evolved, and that this happened more than once.

This paper is a great for teaching phylogenetic trees.

"Ancient DNA reveals elephant birds and kiwi are sister taxa and clarifies ratite bird evolution"

Clearly written. It discusses hypotheses of relatedness among species via continental drift vs genetic data. 🧪
