Sincere question, @trevorabranch.bsky.social : how do these spawning stock biomass estimates compare to estimates from the 1960s, or even earlier? This recovery is great, and clearly better than not recovering... but is this also a case of shifting baselines?

One challenge: "The study only included preprints that were eventually published in a journal and so did not assess the veracity of unpublished preprints." So, of preprints good enough to be published, eventually, changes to the abstract were minor. Much less provocative a finding.

John Stinchcombe @johnstinchcombe.bsky.social · 11/06/2026
Hederacea in contrast is highly selfing (>90%), suggesting that selfing won't provide a transmission advantage to white flowered individuals relative to purple. We also hypothesize, based on the phenotypic and genetic rarity of this deletion, that selection acts directly against anthocyanin loss.
110
John Stinchcombe @johnstinchcombe.bsky.social · 11/06/2026
Why so rare, especially compared to flower color polymorphisms in the closely related Ipomoea purpurea? (I think @gbaucom.bsky.social sent me these images from her field work). First, purpurea is mixed mating, and white flowered alleles getting a transmission advantage from selfing.

John Stinchcombe @johnstinchcombe.bsky.social · 11/06/2026
The deletion is absent in any of our other sequenced lines, and this is the only white-flowered individual my lab or I have observed in 25+ years working on Ipomoea hederacea. We have never seen this phenotype in > 750 lines we have collected and maintained in my lab.

John Stinchcombe @johnstinchcombe.bsky.social · 11/06/2026
We next sequenced the genome of the white flowered individual, and compared to our recent collection of sequenced lines. These lines were all purple, and included the pigmented parent. A coverage analysis indicates a deletion of half the BZ1 locus, including the start codon.
