Though the puma didn't come out on top here, the species' resilience is unquestionable! Genetic analyses from Onorato et al. show a 20x increase in effective pop size and reduced signs of inbreeding in FL pumas after genetic rescue from Texas pumas. www.nature.com/articles/s41... #2025MMM #RIP

#2025MMM CHAMPION: POLAR BEAR

Thank you so much for following along, and we can't wait to see you next year for #2026MMM!

Remember: if you're learning, you're winning!

Oh look, #2025MMM is almost over and *gasp* surprise, a carnivore is going to win 🙄. Again 😑. And I'm not saying there's a #conspiracyoflemurs there, I am willing to believe an order that evolved to eat other animals will do well at MMM @mmmletsgo.bsky.social - I think there's a deeper problem, a 🧵

Reductions in genetic diversity have been correlated w/ reduced fitness (reproductive output & lifespan) in several puma pops in FL and CA. These declines are often associated w/ physical defects like kinked tails, sperm defects, & other cardiac abnormalities. www.cell.com/current-biol... #2025MMM

Microsatellites + SNPs + field data reveal a pedigree up to 6 generations for 4,449 polar bears in western Hudson Bay, Canada! It suggests that these polar bears rarely breed w/close relatives, occasionally have monozygotic twins, and sometimes adopt cubs! #2025MMM doi.org/10.1007/s00300-015-1871-0

The genomes of Roots and Relicts help understand the evolution of sibling lineages. Wang et al 2016 looked at gene expression for ovules and leaves in Ginkgo and find common mechanisms in genes expressed in the ovule related to flowering genes in angiosperms #RIP #2025MMM doi.org/10.1007/s112...

Polar bears and brown bears are close relatives but have very different diets! Polar bears (which eat mostly seals) have fewer copies of the gene AMY1B (important in starch digestion!) relative to brown bears (which consume plants for >70% of their diet). #2025MMM doi.org/10.1073/pnas.1901093116

Guo et al 2016 sequenced the ginkgo mitochondrial genomes to look at common features of gymnosperms. The Ginkgo mitogenome is relatively small, have low substitution rates, and possess numerous genes, introns, and edit sites; all present in the ancestral seed plant. doi.org/10.1093/molb... #2025MMM

Should geladas be divided into 2 species? Chiou et al. found that Northern geladas (2n = 44) have a fission of chromosome 7 compared with Central geladas (2n = 42) & all other papionins! This may affect gene flow within geladas! #2025MMM #RIP doi.org/10.1038/s415...

Caldon et al. (2024) sequenced genomes from the 3 major gelada pops (north, central & south) & found S pops have + pancreatic amylase gene copy #. More tuber consumption when grass is scarce may serve selection pressure for more efficient processing of starchy food! #2025MMM doi.org/10.1111/mec....

Genome sequencing confirms that pumas colonized N. America from S. America ~100-300mya. However, fragmentation has left many N. American pops w/ low diversity and long ROH (signature of recent and severe inbreeding). #2025MMM www.nature.com/articles/s41...
