Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

🚨We're hiring! The Sam Noble Oklahoma Museum of Natural History is seeking a tenure-track split position as Assistant Curator of Ichthyology and Assistant Professor of Biological Sciences. Please retweet & share with colleagues! 🐟🐠🧪

Apply here: apply.interfolio.com/174674
A job ad with multiple images, including the exterior of the museum, a view of collections (jars on shelves), and pictures of some cool, tropical fish but I don't know enough about fish to describe them other than to say they're pretty colors of yellow and blue/green

Microsynteny analysis informs cypriniform fish evolution - one of the most speciose groups of vertebrates. What's in those blocks of collinear genes unique to each lineage...?

Check out our new preprint! We compare sequence versus synteny approaches for resolving a challenging #phylogenetic problem. In this case, synteny is far more informative! Also includes the first chromosome-level #genome for the enigmatic #fish family Gyrinocheilidae. doi.org/10.1101/2025...

Are digits modified fins, or evolutionary innovations? Read how we tackled this old question from a new angle🧪
A story with @chasebolt.bsky.social, @homeobox.bsky.social and myself, coordinated by @denisduboule.bsky.social from @college-de-france.fr and published in @nature.com today!

Man I really like these guys, Chinese suckers Myxocyprinus asiaticus. They change as they become adults and get too big for any tank I'll have for the foreseeable future. I was involved in the genome paper on them. academic.oup.com/gbe/article/...

Cool paper. taars also involved in olfaction (cadaverine) for spawning, perhaps pleiotropy speeds it along or tradeoff? We see them pop out in genome scans in other fish.

If the DNA is sufficient quantity/quality it should sequence on ONT; sometimes pores clog/die quickly if secondary structures (e.g., g-quadruplexes) or chemical contaminants / DNA adducts present. Or digestive enzymes a problem in these perhaps? Could be cool biological underpinnings!
fishgenomes.bsky.social
Sequence quality is low/short or assembly is poor or both? Filter out stickleback reads before assembly? We like ONT for almost everything, especially now that Hifiasm has ONT mode - that was significant improvement for assemblies.

I'd highly recommend the species selection chapter of Gould's 'Structure of Evolutionary Theory' for this thought experiment. Ecosystems have emergent properties (good re selection on 'immune system') but don't meet the criteria of being 'individuals', whereas species meet both criteria in my view.
fishgenomes.bsky.social
Agreed. Not at community-structure level but at species level I see your argument and think that works. Interesting discussion, thank you!
fishgenomes.bsky.social
But I do buy species-level selection (a la Gould), and so lineages could be selected on the basis of their resilience to other species (plays well with others-type species) vs not, so maybe your model works at that level?
fishgenomes.bsky.social
I agree that multiple rounds of invasion can have cumulative (or beyond) detrimental effects and meltdown can occur (a likely outcome). I don't see how the 'immune system' adapts in this case to increase resilience after invasion (the opposite phenomenon) because community structure isn't heritable?
fishgenomes.bsky.social
(quick skim) That paper involves (experimentally) teaching prey species to avoid predators so individuals with the learned behaviors are more likely to survive. If the behaviors are somehow heritable then yes, that is fine. Is your argument only that we can teach naive prey to avoid invasive spp?
fishgenomes.bsky.social
Hmm, interesting question, but I don't think it works. What is ecosystem immunity in real terms? Community structure varies over time but doesn't 'evolve'; it isn't heritable. Invasions seem more likely to destabilize deep-time co-evolved interactions between spp. in favor of novel interactions?
fishgenomes.bsky.social
Agreed. For the annotation, if a reasonable number of genes are present, I'd next check how many single exon genes are there. Split gene models (exons being called different genes) a common driver. I like gene length histograms and exon counts as a metric to complement gene counts and BUSCO.
