Preparing for the next field season! Excited to finish sampling the multiple Flame-rumped/Lemon-rumped Tanagers hybrid zones and test our 3D printed models 🤩🇨🇴 (those rump feathers though 😮‍💨) @cdanielcadena @TropBioLab

Replicate avian hybrid zones reveal the progression of genetic and trait introgression through time | our latest, led by the amazing maria isabel castaño #cienciacriolla biorxiv.org/content/10.1101/…

Replicate avian hybrid zones reveal the progression of genetic and trait introgression through time

Replicate hybrid zones between the same taxa provide a unique opportunity to assess the repeatability of interspecific matings by uncovering recurrent genomic and phenotypic introgression patterns....

🚨 Back on X to share that our paper with @AvispaTica at @TropBioLab was published @ScientificData! I wanted to learn bioinformatics during my first year PhD rotation, and we ended up doing the first long read de novo genome assembly of a whole order of insects! #Strepsiptera

In this paper we report the first long read de novo genome assembly and annotation for a male Xenos peckii and one of the smallest insect genomes reported up to date! We also assembled the mitogenome and identified two contigs with X-linked coverage patterns.

Exciting hybrid zone research on flame-rumped tanagers by @MariaCastanoGal including RNAseq of red, orange, and yellow feathers and carotenoid-related genes. #AOS_SCO23. Fascinating system, rockstar scientist!

We made it! Three months of fieldwork, massive landslides, amazing Colombian landscapes and more than 130 Flame-rumped Tanagers 🔥 ready for some 🧬🤓

Today we caught all these birds in the same locality. What lies behind the phenotype of the Flame and Lemon rumps? Stay tuned to know more 🤯 @TropBioLab @cdanielcadena

“I’m trying to describe how the birds’ genes change along the distribution of the species and if the plumage color changes in concert with the genes,” says third-year PhD student Maria Castaño of her research on various flamed-rump tanager species rochester.edu/newscenter/bir…

more species of birds live in this photo than in the entirety of Canada this is what elevational zonation looks like, amazing photo

One answer to the question - why is Colombia a megabiodiverse country? The spectacular view from the Caribbean sea to the glaciers of peak Gonawindua (Pico Cristobal Colon) at 5,775 m above sea level.
