We use a freshwater mussel, Potamilus streckersoni, as a model to better understand sex determination in bivalves with biparental mitochondrial inheritance. RNA and mitochondrial sncRNA sequencing provided empirical support for mitochondria inhibiting sexual development.

We did not identify a nuclear sex determining region using whole genome resequencing, but high differention in genes across the entire genome, conistent with polygenic sex determination. In sum, our findings support a compelling case of mitonuclear sex determination in bivalves.

Stoked about our new paper in @PNASNews! Using new genomes from #Scaphopoda, we found support for Scaphopoda Bivalvia (Diasoma) and evidence that ILS may be to blame for previous incongruence on relationships among gastropods, bivalves, and scaphopods.

Mussel-mania is here! #MassDigitization has partnered with the @NMNH Department of Invertebrate Zoology to image a treasure trove of freshwater mussels! Specimens from the 25K lots of freshwater mussels will have 3 fabulous #shellfies taken for more than 120K images total.

Latest #JHered issue is out, with this handsome guy on the cover. And more squamates inside - a squamate genomics review and a new leopard gecko reference genome by @DrPintoThe2nd & others, & the western fence lizard genome by @anusha_bishop & others.

New publication - we find an interesting case of mistaken identity! We show the federally threatened Texas Fawnsfoot (Panels E-G) is present in the Trinity River, and not the common and widespread Fawnsfoot (Panels C-D). Big conservation implications!

A case of limited morphological divergence in closely related species. John Strecker, former curator at @MaybornMuseum, hypothesized this distribution in the early 1900s. Strecker's distributional work has been accurate in many cases, which has been supported using genetics

New paper 🚨. Our new study uses historical DNA and DNA barcoding to redefine the range of the soon to be federally threatened Louisiana Pigtoe. We expand the range east to the Pearl River and confirm its historical presence from the type locality using a 1800s museum specimen!

My lab is recruiting graduate masters or PhD students to start in January 2023 or August 2023. Anyone interested in genomics, systematics, or conservation, should consider applying.

A great article on my PhD advisor Robert Doyle! Robert and his wife Eva created a study abroad program for Baylor students in Brazil, which allows students to engage in global and environmental health initiatives. Read more about it here: robbins.baylor.edu/news/stor… via @baylor

Our work highlights an intriguing case of coevolution among mussels and catfish. This work was led by Sakina Neemuchwala, who performed this research with me as an undergraduate at UT-Austin and is now in medical school at UT-Southwestern.

I'm excited to announce our new preprint titled "Mitonuclear sex determination? Empirical evidence from bivalves". Our work uses WGR, RNA-seq, and mitochondrial sncRNA sequencing to investigate the sexual development pathway of Potamilus streckeroni

Given mussels have biparental inheritance of mtDNA, it has been hypothesized mtDNA play a role in sex determination. We found support that male mtDNA play a direct role in male development by silencing female developmental pathways through RNAi.

We were also unable to identify a nuclear sex determination, providing empirical support that mtDNA may act as a primary sex determiner in mussels.
