Do you want to know when your favorite species activates its genome?

Just input its genome size (🧬 in bp) and egg volumen (🥚 in um3) here!

ZGA_onset = -2.37 * log10(gDNA/EggVol) + 11.74

Wildlife trade drives animal-to-human pathogen transmission over 40 years The wildlife trade affects a quarter of terrestrial vertebrates and creates opportunities for cross-species pathogen transmission, but its precise role in shaping animal-human pathogen exchange remains unclear. In our analysis of 40 years of global ...

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

Epigenetics in Captivity: Restoring Wild Phenotypes in Captive‐Reared Salmonids Captive rearing is a common practice for the stocking, conservation, and supplementation of fish species worldwide, but captive-reared fish can exhibit altered phenotypes leading to reduced fitness i...

My lab’s first publication is out now! MSc student Tia Attfield reviewed the current captive rearing literature in salmonids and provides perspectives on how epigenomics can help.

Huge thanks to all our co-authors for their expert insights!

We're working through it right now. Pipelines aren't as well ironed as Hi-C it appears. Given the very large contigs we get from HiFiasm ONT-mode, scaffolding really doesn't have much heavy lifting to do.

In a conservation context, need for “genetic rescue” is often evaluated solely at nucleotide level, but perhaps isn't necessary if SVs & pangenomic variation provide the needed “genetic diversity” for ecol success. Among-pop homogenization risk should be given more attention re. "rescue" in my view.

Slightly off topic, but informative re. inbreeding - we also identified the sex chromosomes in brown treesnake and demonstrate their evolutionary origins relative to other snakes, providing information on how sex chromosomes (can sometimes) degenerate over time.

Despite the apparent lack of genetic diversity at the nucleotide level, structural genomic variants (indels, inversions) rescue the pop from inbreeding. Structural variants were often TE-associated and genes affected by SVs were enriched for olfaction – a key feature of their ecol success on Guam.

We assembled a haplotype-resolved genome and found evidence of extensive inbreeding, decline in effective pop size, and extended runs of homozygosity in nucleotide sequence across the genome, as expected based on their invasion history.

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
