Door with three posters, including Biology is Bigger than Binaries from SkypeAScientist, along with In this Lab we Believe (Science is real, love is love, black lives matter, feminism is for everyone, plants are cool, and immigrants are welcome) Also a lab inside joke about poorly drawn dinosaurs from the movie "Drasik Werl" with a QR code that leads to the screeching recorder version of the Jurassic Park theme song.

Taxonomy in the light of incongruence: An updated classification of Malvales and Malvaceae based on phylogenomic data Malvales is a diverse order of flowering plants, economically and ecologically relevant, and it is known for its broad morphological variability. Recent phylogenomic studies have revealed a complex e...

Love this, and need to re-read it again: #Malvales and #Malvaceae #classification\

Figure 3. Plots showing the relative contributions of incomplete lineage sorting (ILS), gene tree estimation error, and gene flow to the observed gene tree discordance, across two datasets and two taxonomic levels The Hyb‐Seq (A–B) and transcriptome (C–D) datasets are represented here by the HYB‐98RT and RNA‐2821RT datasets, respectively. R2 denotes the total proportion of gene tree variation explained by the model. Relative importance with 95% bootstrap confidence intervals is decomposed with the “lmg” method and regressors of log transformations and summed to 100%.

Figure 2. Discordance between nuclear and chloroplast phylogenies for oaks and relatives (A) Cophylogeny showing incongruence between the nuclear ASTRAL (left; HYB‐98RT) and unpartitioned chloroplast maximum likelihood (ML) (right) trees. Tip labels are shown in Figure S15. Clade frequencies of gene trees from the coalescent simulations are shown near the nodes; clade frequencies associated with deep cytonuclear discordances are red and enlarged.

Figure S21. Species networks from reduced-representation datasets of oaks and Fagaceae. A. Optimal network under the “planA” taxon set of Fagaceae using the Hyb-Seq dataset (represented by the HYB-114RT dataset here). B. Optimal network under the “planB” taxon set of Fagaceae using the Hyb-Seq dataset. C. Optimal network under the “planC” taxon set of oaks using the Hyb-Seq dataset. D. Optimal network under the “planA” taxon set of Fagaceae using the transcriptome dataset (represented by the RNA-4853RT dataset here). E. Optimal network under the “planB” taxon set of Fagaceae using the transcriptome dataset. F. Optimal network under the “planC” taxon set of oaks using the transcriptome dataset. Dashed red curved branches denote the minor edge of a reticulate node while solid blue curved branches denote the major edge of a reticulate node. Values next to curved branches denote the inheritance probabilities. A reticulate node with an asterisk denotes that its parents contributed relatively equivalent inheritance probabilities (~ 0.5 vs. 0.5). Abbreviations: sect. CY, sect. Cyclobalanopsis.

Fascinating phylogenomic study of Oak Family by Shui‐Yin Liu et al. (including @carolsiniscalchi.bsky.social) showing that hybridization & ILS both generate gene-tree discordance in the family; ILS contributes ~3x as much as hyb'n to discordance in Quercus, but both matter.

Yeah not super great that a journal dedicated to ecology is happily using AI art when the environmental costs of generative AI is now a well known, widespread issue 🫠

Last Sunday I went to the shopping mall to take a round and I didn't expect to see my target species 🤣
