1/10🚨🚨 New paper out 🚨🚨 I am beyond excited to present our new paper out now in @Nature! Here, we show that rapid gain and loss of tooth complexity accelerates diversification in fishes!

📢Now advertised📢 - the B.A. Krukoff Curator of African Botany, a 3-yr fulltime research role at RBG Kew. We’re looking for a productive early career taxonomist to join Kew’s Africa team! https://t.co/BoLt8VpFlY

Next week I'll be teaching in a workshop at @USanSebastian sede Concepción with @lukejharmon & hosted by Cristián Hernández Ulloa. I believe that enrollment is still open, so if you're local to Concepción, Chile, please check it out!

‼️ATTENTION‼️ Our 2025 application for our virtual #Evolution & #Ecology #Graduate #School Preview Program is live! Please refer to our website (link in bio) for more information We especially encourage individuals from historically excluded groups to apply!🎉

Interested in applying to evolution or ecology focused grad school programs, but not sure where to start?! Check out the E&E Grad School Preview Program to demystify grad school! Applications have JUST opened!!!

Taking tissues from specimens with a lot of interest from the local community. Great opportunity to talk about what we are doing and why these fishes and macroinvertebrates are important.

Come join us. Three permanent academic positions (Lecturer/Senior Lecturer) at @MonashBiol. Supportive research and teaching environment. Fantastic colleagues. A great place to work. https://t.co/XGoJLvUhaf Ecology: https://t.co/SyowTwaHUO Genomics: https://t.co/rEDzI5lsrC

Out today in @PLOSBiology! We show that two major advances in fish feeding - highly protrusible jaws and large teeth - are functionally and evolutionarily incompatible with each other. @MikeMihalitsis and Peter Wainwright. Free to read:

Super excited that our new paper is out today in @pnas. Title: Lateral jaw motion in fish expands the functional repertoire of vertebrates and underpins the success of a dominant herbivore lineage. https://t.co/PM4tyXkAA2

Happy to share my new article on how morphological diversification proceeds during evolutionary radiations: "The diffused evolutionary dynamics of morphological novelty" https://t.co/v9cB2KyNW4 🧵1/12

Happy to share our new preprint: `The rise, decline and fall of clades' with @JyAndreoletti, Daniele Silvestro and @HMorlon , where we study how the biodiversity of clades rise and fall, and the processes behind these patterns. 1/5

Out now in @IAGLR

🚨New paper out about the impacts of cage aquaculture of Nile tilapia in Lake Victoria! The first from extensive field sampling efforts over the last 3 years. Led by collaborators from @KmfriResearch. Read it here: https://t.co/9uL79JQTB3

Happy to share our new study published today at Proceedings B! 🐊 @RSocPublishing @SebastianHoehna 📝 “The effects of cryptic diversity on diversification dynamics analyses in Crocodylia” https://t.co/15t7baPGwC #crocodylian #species #macroevolution 🧵 (1/7)

🐟✨ Unbelievable Moment! ✨🌍 As we pulled the net from Lake Victoria, I knew—we found something special! I shouted & showed it to @OleSeehausen. His reaction? "This is unbelievable, Anna!! Lipochromis microdon!" Once thought extinct, now rediscovered! 🔬💙#Conservation

10/10 We suggest that the evolution of many other traits, not typically considered key innovations, could affect species diversification in this way. Many thanks to coauthors Mike Burns, @MikeMihalitsis and @PeterWainwrig15. #fish #teeth #evolution @ucdavis

9/10 These results suggest that the combination of uniquely high evolutionary lability and the ecological versatility of complex teeth drove diversification of cichlids in Lakes Malawi, Victoria, and Barombi Mbo. A new explanation for why these groups diversify so rapidly!

8/10 But having complex teeth is still a benefit. When lineages have complex teeth, they switch between different diets at much faster rates. This ecological versatility is elevated because complex teeth allow transitions through herbivory and omnivory.

7/10 When we fit SSE models, we find lability (greens) consistently increases speciation rate, despite high background rate variation. So, differences in lability explain speciation rate differences within rift lakes AND across habitats – separating out the “rift lake” effect.

6/10 Investigating this with more complex Bayesian models, we find that even within African cichlids, there are differences in lability. Lability is much higher in Lakes Malawi, Victoria, and Barombi Mbo – exceptional adaptive radiations.

5/10 But the distribution of high lability is uneven. This is concentrated within African cichlids (and NOT neotropical cichlids). The prevalence of lability of tooth complex in African cichlids is unique!
