Genomic structural variation rescues a classic biological invader from a population bottleneck

Genomic structural variants rescue a textbook biological invader from a population bottleneck and inbreeding.

Biological invasions present an interesting paradox: often little genetic variation is accompanied by dramatic ecological success. Led by PhD student Chris Osborne, we evaluated genetic diversity in a classic invader, brown treesnake on Guam. www.biorxiv.org/content/10.6... Photo: Pavel Kirilliov

Did Thoreau encounter contagious cancer? A new study finds transmissible tumors in catfish--and raises questions about whether they could arise in humans someday. Gift link: nyti.ms/4whfi6v

Deep in This Lake, a Contagious Cancer Is Spreading (Gift Article)

Transmissible tumors have been reported in a handful of animal species, but never before among fish. Is it possible in humans?

There’s been hints that #ColossalBio has been playing fast and loose with their #RedWolf conservation plans and so–called ghost red wolves, of course along with very clickbaitable headlines. This thread is an excellent explainer, as is this video 🐺 👻 m.youtube.com/watch?v=V9fL...

Then, what determines ZGA onset?? We correlated multiple genomic, developmental and ecological features with ZGA timing and, cutting to the chase, we found that the log ratio of genome size vs. egg volume very strongly scaled negatively with ZGA onset in cell cycles! 7/15

The global wildlife trade—especially in illegal and live-animal markets—is fueling the spread of diseases from animals to humans, according to a new study in Science. The findings show that traded mammals are more than 40% more likely to harbor human-infecting pathogens. https://scim.ag/41SZkSq
