@fusaroli 🥹 Thank you! Yours too!! I have been reading your recent work because we are trying to think about prosody analogues in birdsong!

@pichkary @AbigailSearfoss We also found that some chipping sparrow songs were sung by many individuals over a long time period (>50 years) and some were only observed once. The long-lasting songs were sung faster (they were made up of more, shorter syllables) 🐦

@pichkary @AbigailSearfoss We simulate chipping sparrows learning from a random neighbor, the most common song, or the fastest song. When we compare our simulated results to real data, it seems like chipping sparrows might try to learn the best song around them!

Excited to share a publicly accessible link to new work with @pichkary and @AbigailSearfoss -- detecting cultural evolution in songbirds (chipping sparrows!) using community science data and computational modeling authors.elsevier.com/a/1icLxmjM6FRC

Nicole Creanza on the interactions between socially learned song and speciation in songbirds #smbe23 #smbe2023 using data from @Team_eBird

@ATJCagan @Team_eBird Thank you for the amazing visual summary! (Of both the talk and my bird dress 😅🐦)

Our results suggest that past populations might have mated assortatively with speakers of the same dialects or those who shared other other associated cultural features.

We analyzed two separate datasets (library.leeds.ac.uk/special-collec… and peopleofthebritishisles.org)–both sampled people with multigenerational ties to rural+agricultural locations, so our data are linked to 19th century England, not to more recent movement and mixing

Genes and languages have worldwide signatures of human history – but does variation *within* a language correspond to genetic population structure? @pichkary examined pronunciation of English words and found greater genetic differences at dialect borders: onlinelibrary.wiley.com/doi/full/10.10…

A nice summary is here, too! @EvolutionVU news.vanderbilt.edu/2023/06/20/tra…

Big congratulations to newly minted Dr. Kerri-Ann Anderson, who successfully defended her PhD and has a new paper out modeling the interactions between vaccine hesitancy and vaccination behaviors! sciencedirect.com/science/articl…

Speaking of @kelly__tingle, 👀 this great piece titled, "Specialization and Cultural Evolution," featuring the @CreanzaLab! "The cultural #evolution of a population depends, not only on size but also on the degree of specialization within a population" loom.ly/Dt1MrT4

How might population contact affect the tools and technologies of a population? Happy to see this paper out, featuring the work of former undergrad Sarah Saxton Strassberg (now a PhD candidate at UChicago!) and wonderful collaborators @YotamBenOren @orenkolodny @ErellaEhovers

Really interesting article by the @CreanzaLab! Fascinating to think of cultural specialization as a quantifiable metric and even more so to think about the role of population size on it

What happens when some members of a population have specialized knowledge? Our model predicts that if the population is large enough, their cultural repertoire could expand, but if it is too small, the specialized knowledge could be lost. royalsocietypublishing.org/doi/10.1098/rs…
