1/9 Excited to share the preprint for the second half of my PhD with @mollyschumer.bsky.social: Connecting human environmental impacts to hybridization in swordtail fish through genomics, GIS, water chemistry, and histology. Thread below! #SciSky www.biorxiv.org/content/10.1...

Increased rates of hybridization in swordtail fish are associated with water pollution

Biodiversity loss can occur when disturbance compromises the reproductive barriers between species, causing them to collapse into a single population through hybridization. Recent research has documen...

Congrats to @jeffgroh.bsky.social et al on publication of "Ancient structural variants control sex-specific flowering time morphs in walnuts and hickories" www.science.org/doi/10.1126/...

Science magazine front cover. Picture of a walnut in its opened shell. The text reads "All about timing. Mating type evolution in walnuts and pecans"

graphical abstract:
"In Juglans (top left) and Carya, two morphs show complementary temporal separation between male and female flowering (heterodichogamy). Mating types are controlled by two nonhomologous single-locus mechanisms that arose in the common ancestor of each genus, respectively. (Bottom left) Simplified schematic of a putative functional regulatory element at the Juglans locus. (Bottom right) Strong genotypic correlations across the Carya locus indicate a lack of recombination between two colinear haplotypes with similar gene content."

So glad our paper on lethal hybrid incompatibilities is out at Nature today: rdcu.be/dvFcM ! @ben-moran.bsky.social moved mountains for this project: we identified two new incompatibilities in swordtail hybrids , characterize mechanisms of lethality, and their evolutionary history.
