The Iberá Seedeater, a recently described species from Argentina, has a unique plumage that is a product of mixing coloration genes from closely related species. These differences are enough to prevent it from interbreeding with its close relatives. https://t.co/yyVQZ3pDvP

Today we presented the preliminary results of my PhD project with @evoleoC and Cecilia Kopuchian at @Evol_mtg #Evo2025

The reason biologists in your timeline are furious by this PR: the idea that species that diverged millions of years ago have only 20 genetic differences defies the fundamental principles of evolution. Like saying you turned a Honda Civic into a Formula 1 car by changing the oil

How do different types of genetic variants contribute to Capuchino Seedeater evolution? @MariaRecuerda built a pangenome from 32 HiFi genomes, recovering 28% more sequence and 8% more genes than with a single reference. More here: https://t.co/YgTTkvIsNC

Hoy empezamos el Taller de Genómica Evolutiva 2024, en Bogotá, Colombia. Gracias a @selvaorgco @Uniandes @sse_evolution @CornellBirds @KentState

My study on territorial behavior and breeding philopatry has just been published (open access, @FieldOrnith). It is the result of my doctoral thesis. https://t.co/yHqBbDJJqL

Come check the poster I'm presenting with @evoleoC and Cecilia Kopuchian about my PhD project with Capuchinos at Esteros del Ibera. #Evol2024 #Evolution #Sporophila #Capuchinos

How do structural variants shape avian phenotypes? This is what @MariaRecue13274 learned mainly from chickens. https://t.co/2iMGkuw6Oy (pic by Dennis G. Jarvis - CC BY-SA 2.0)

@KalteneggerLisa, director of @CSInst at @Cornell, hunts for aliens in space by studying Earth across time, reports @beckyferreira for @nytimes.

That’s about half the annual salary of an university professor in Brazil.

In 2013 Márcio Repenning and Carla Fontana described Sporophila beltoni. In our new paper, @Tram_N_Nguyen and I teamed up with them to show how S. beltoni diverged from S. plumbea with a few genomic regions resisting introgression, despite high gene flow. https://t.co/DyV0dMrOLK

“Variant scores calculated by GATK did not clearly distinguish true positives from false positives in the vast majority of cases, implying that hard-filtering with GATK could be challenging… results suggest that Bcftools mpileup may be the first choice for non-human studies”

Hi Everyone! join us on 5th DEC 5pm CET for the next IOS seminar. Catherine Wagner and Carlos Daniel Cadena Ordoñez will give us a macroevolutionary perspective of speciation. Link on website https://t.co/Aa5kgQjDkd

We are excited to announce Christina P. Riehl as the next editor-in-chief of the AOS journal, Ornithology. Dr. Riehl is an assoc. professor in the dept. of ecology and evolutionary biology at @Princeton. Read our full announcement. https://t.co/KCwJSiKSCj #ornithology #research

📣 I'm recruiting!! 📣 Open position for a postdoc in disease ecology/evolution. Do you like birds, pathogens, or genomics? Do you want to work in the Galapagos? Apply by July 1 for best consideration. Start date flexible. Contact me for info & please RT! https://t.co/pu8GB1V8mi

Very pleased to release FlexSweep and some new summary stats, designed for versatility in detecting selective sweeps of different types and robustness to background selection, demographic model misspecification, and recombination rate. 1/n
