Assistant Professor of evolutionary biology in the Ecology, Evolution, and Marine Biology Department @ucsantabarbara.bsky.social, interested in mito-nuclear and plastid-nuclear interactions. (he/his)

Dear Colleagues, It is with immense sadness and shock that I share the passing of Dr. Adriana Romero Olivares, a brand-new Assistant Professor in the Department of Evolution, Ecology, and Organismal Biology at UC Riverside. www.mealtrain.com/trains/l3kg64

Meal Train for Jovani Catalan (Spouse of Adriana Romero Olivares)

Hi all, Please help out the family of Adriana Romero Olivares. Her husband, Jovani, and kids can be helped with meals over the next weeks as Adriana recovers.

It took forever but my last paper as an academic is finally out. ironically this paper probably has the smallest audience, but I believe is my most impactful work. I think it provides some nice support for theories on polyploid origins, and has practical implications in crops and conservation

Recombination and the role of pseudo-overdominance in polyploid evolution

Abstract. Natural selection is an imperfect force that can under some conditions fail to prevent the buildup of deleterious mutations. Small population siz

Latest work from our group together with @jsharbro.bsky.social This review synthesizes insights into cytonuclear incompatibility in plant hybrids and allopolyploids, highlighting maternal bias, evolutionary consequences, and applications such as cytoplasmic male sterility in seed production.

Causes and Consequences of Cytonuclear Incompatibility in Hybrids of Flowering Plants

Abstract. Hybridization and polyploidization combine divergent nuclear genomes with maternally inherited organelles, often disrupting cytonuclear coadaptat

The National Science Foundation sign on our Eisenhower Av building is now gone. The NSF mural in the foyer is removed and torn off in sheets. We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

NSF building on Eisenhower Av. HUD now owns. Destroying the NSF mural in the foyer. Of the Eisenhower building.

I am recruiting a MS student in Biology at New Mexico Tech with an anticipated start date of Fall 2026 to work on the applied evolutionary genetics of wild populations with conservation or management concerns (butterflies, bighorn sheep). Please see the attached advertisement for more info.

We (Nordborg & Weigel labs) need input on the next generation of genome browsers & data download modes for the #Arabidopsis #1001GenomesPlus project. We have now a curated collection of over 500 long read genomes. Please help us by filling out this questionnaire: docs.google.com/forms/d/e/1F...

Next generation of 1001 Genomes Plus browser and data download

Please indicate all features you would like to see in a browser that displays features of completely sequenced Arabidopsis thaliana genomes

NSF - Forced reorg - POs down ~ 40% (DRP, most rotators not renewed, retirements) - Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …) I personally love the boxes they gave us for packing. “Details matter” 🙃

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

I am looking for a PhD student to start in my lab at UCSB in Fall 2026, studying evolutionary biology. See attached flyer for more information. Please also share with potentially interested students. Thanks!
