Today also, @thorstenreusch.bsky.social presented the fascinating work conducted on somatic mutations in the clonal seagrass Zostera! ✨ #ESEB2025

Also appreciated the citation format used: Author, year, unique keyword. No journal name 🙌

Inspiring talk from @marcrr.bsky.social presenting student Christabel Bucao’s work. Expression variability predicts retention and functional divergence of genes after WGD! « variability creates » #ESEB2025

YouTube video by Rosana Z-F Zenil-Ferguson. The importance of quantifying rate uncertainty

Unfortunately, I couldn't join in person #eseb2025, but the organizers kindly accommodated a video. Posted here in case you missed it!

pangenome 'expansion' curves for cotton and soybean

Determining presence-absence variation (PAV) across reference genomes is a major goal of pangenome analysis. It turns out that A LOT of gene PAV is due to methodological artifacts.

We explore the causes of this in soybean and cotton datasets in our recent preprint: www.biorxiv.org/content/10.1...

Qques mots forts que j'ai prononcés avec émotion @franceinfo.fr
C'est un mensonge de laisser croire que l'on s'adaptera sans casse irréversible dans une France à 4°C. On ne s'adapte pas a un effondrement de la biodiversité; on meurt avec!
Les régressions actuelles sont irresponsables & suicidaires.

Fig. 3 | DEEPSPACE synteny map highlighting positions of centromeric repeats. Collinear blocks between the same chromosomes are shown as transparent ‘braids’ and chromosome segments are visualized as color-gradient rectangles along an x-axis that scales each genome by its physical size. Regions that do not map between chromosomes are visualized as black ‘wedges’ in the map. These can be due to ineffective unique mapping in highly repetitive centromeres (e.g. Chr 9 IM62-IM767), expansion of centromeric arrays (e.g. Chr 11 IM62-IM767) or sequence presence/absence. The orange-blue color gradient indicates regions that are gene-rich (blue) or centromeres (orange); fully saturated colors indicate that all sequence in those intervals is masked by that annotation type. White regions have neither genes nor Cent728 repeats, and are likely repeat-rich pericentromeres.

Fig. 4 | Exploration of the pan-genome graph. A 2.34-2.37Mb on chromosome 1 is a complex region in the genome that illustrates how the pan-genome graph handles large scale presence594 absence variation. Here, any variants smaller than 52bp are excluded so that the large insertion deletions in this region are apparent. Haplotypes containing similar sequences are binned in the transparent rounded rectangles (“nodes”), divergent but syntenic/orthologous sequences have stacked nodes, and deleted sequences show the path outside of a node. B The first exon and the first 28bp of the first intron of a gene with family members across all four genomes is shown as an example of how SNPs and INDELs appear at the base pair level in a sequence graph. C The positions of aligned sequence retained in the graph (colored following the tubes in panels A-B) and that which is un-alignable and clipped (black) are presented in a pan-genome anchored by IM62.

Ooh, I've run a session on basically "How to Conference" for the undergrad diversity program at the Evolution conference for the past few years. Some of what I cover:

This week in my graduate-level Science Communication class, we're discussing scientific conferences, including how to find a conference that's helpful for you, how to make the most of attending a conference, networking, and effective presentation skills.

Anyone have any advice to share? 🧪🦑🌎

The Earth seen from Apollo 8 on Christmas Eve 1968. Picture taken by Bill Anders.

At an Earth Day event this evening, I was asked to talk about the 'Overview Effect' - the profound sense of awe many people feel when seeing the Earth from space.

Global map (Equal Earth Projection) showing surface temperature changes (based on linear trends from 1970 to 2024) from GISTEMP. Color bar is even (blues to reds) from -5 to 5ºC. Map is all red (except for a few spots in the southern ocean, and is more red over land, and most red in the Arctic region, which has warmed by more than 4ºC. Title: "Since the First Earth Day, the planet has warmed 1.1ºC". Subtitle: "(That's 2.0ºF or about a fifth of an ice age)".

Happy Earth Day!

Satellite-based evidence of recent decline in global forest recovery rate from tree mortality events - Nature Plants Satellite data show declining global forest recovery from tree mortality since the 1990s, driven by warming and water scarcity.

Our new research shows that forest recovery from tree mortality has slowed in recent decades. This reduction is primarily associated with rising temperatures and increased water scarcity. Recovery of forest canopy water content lags behind that of vegetation greenness
