The Comparative Analysis of Lineage-Pair Traits
Abstract. For many questions in ecology and evolution, the most relevant data to consider are attributes of lineage pairs. Comparative tests for causal rel

New preprint characterizing diverse hybrid dysfunction phenotypes (sperm, gonads, copulatory structures) despite no detectable pre-zygotic isolation, work led by students Maia Dall'Acqua and Amanda Peak (now with @johnstinchcombe.bsky.social ) #celegans www.biorxiv.org/content/10.1...
A constellation of dysfunctional hybrid phenotypes enforces reproductive isolation between Caenorhabditis nematode species
The evolution of complete reproductive isolation hinges on the cumulative action of reproductive isolating barriers that can manifest throughout the life cycle of an organism. Consequently, a comprehe...

Very excited to dive into this work on time-varying outcomes of hybridization & fitness landscapes by Schneemann and Welch www.biorxiv.org/content/10.1...
When will hybridization bring long-term benefits?
Hybridization between distinct populations injects genetic variation, which can bring fitness benefits. However, these benefits often appear as F1 heterosis, and might not persist into later generatio...

Just accepted #EcologyLetters! Exciting work by recent grad Rebecca Schalkowski with @katjakasimatis.bsky.social and Megan Greischar linking 2 species community coexistence to sperm cell mediated reproductive interference! Preprint here www.authorea.com/users/804447...
Reproductive interference alters species coexistence in nematodes due to asymmetric sperm-induced harm
Species coexistence is shaped by a range of biotic and abiotic factors. Beyond predation, parasitism, and competition, one species may interfere with another's reproduction to induce sexual exclusion ...

Ok people. I’m drawing silhouettes this afternoon. If you have a paper coming up and you are in need of a #silhouette please let me know and I will have it ready today. As always I upload all my silhouettes to phylopic.org

I also have tutorials on how to put a silhouette in a plot in R.

Hey BlueSkyers, we’re finalizing a #meta-analysis 📚 on comparative studies examining the link between #SexualSelection and #Speciation. If you have unpublished data or know of studies that might not surface in a systematic search, please reach out - we’d love to include them!

Please share!

Increasing crop diversity is likely to be crucial for future food security. Domesticating more types of crops might be one way of achieving that. 🧪

Achieving that will call for more collaboration, exchange, and a bit of opening to new things.
