On March 3rd @ 5pm CET, we are re-starting the Integration of speciation seminar series! The first 3 sessions feature talks by *Early-Career Researchers*, and include a Q&A with an established PI about their career path.

Moreover, we find that polyploid species have more loci under positive selection, particularly in genes relating to chemical defence against herbivores, a key ecological pressure on tropical trees 🐛

🌿Excited to share our new study in New Phytologist! 🌿
Polyploidy is a major force in plant evolution, but is understudied in the tropics. We find that polyploidy evolved multiple times in Inga, a characteristic Neotropical tree radiation (1/n) 🧵.

The frequency and importance of polyploidy in tropical rainforest tree radiations The presence of two or more copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. The Amazonian tr...

Allowing proportion (or alpha) to be free in our models allows us to use nQuack to estimate mode of inheritance - which is exactly what @rschley.bsky.social did in our new paper. Check it out here: doi.org/10.1111/nph.... (4/n)

Everyone should read this. I met Dan Janzen when he gave a lecture to @biology.ox.ac.uk I think in the late '80s. I spoke to him afterwards and he said, you know we could save all of the rainforest with a ten cent levy on every cup of coffee sold worldwide....

No evidence of transposable element bursts in the Galápagos Scalesia adaptive radiation despite hybridization, diversification and ecological niche shifts - Mobile DNA Transposable elements (TEs) have been hypothesized to play a pivotal role in driving diversification by facilitating the emergence of novel phenotypes and the accumulation of divergence between specie...

🌳⚠️Out now in Systematic Biology⚠️🌳
We find rampant reticulation in Inga, the blindingly rapid Amazonian tree radiation! ⚡

BONUS: We also find introgression and selection on genes underlying chemical defences, helping Ingas resist relentless insect herbivory 🐛☠️🌳
