Excited to talk about structural variation and pigmentation at #SMBE2024! Today @ 4pm in the Structural Variation Symposium (Costa Alegre - upstairs)

If you have played Wingspan, could you please fill out this quick survey on Wingspan & birding for me? Birders & non-birders welcome. RTs appreciated. https://t.co/GvgGpxKY2c

Excited to finally get R10.4.1+Q20 & looks like @nanopore only assembly is the way to go. Major yield & accuracy boost a bonus to our upcoming effort to sequence all of family Drosophilidae (@PetrovADmitri @danrdanny @danielrmatute @DarrenObbard @_hgellert @mbeisen et al)

[Tris Dodge @TrisDodge]

High quality reference genomes are no longer just for model organisms! Excited to share our work describing conservation insights from the new reference genomes of 2 Extinct-in-the-Wild reptile species. This also happens to be my first first-author paper! https://t.co/mvBGOCiB8P

De novo genes emerge often but finding them can be challenging.
How can we scale up their identification?

We explored if machine learning algorithms (MLAs) can accelerate the detection of de novo genes.

New work out led by @ryanjweaver_ showing strong signatures of mitonuclear coevolution in mammals, but limited evidence for nuclear compensation. Very cool and convincing results!

New work out in preprint! Here we explore a previously unreported and complex hybridization event involving sister species Xiphophorus malinche and X. birchmanni and the much more distantly related X. variatus

[Tris Dodge @TrisDodge]

I wrote a short blog post about the research I’ve been doing in Australia for the past 6 months and why we should care about 2 small lizards from Christmas Island. Stay tuned for the paper! https://t.co/9kAuQmYVgA

[Daniel Powell @Daniel_L_Powell]

Further, by testing male cues against water blanks we show that the flip in valence for calcium hydroxide exposed females is the result of an induced indifference toward conspecific male cues coupled with a strengthened preference for heterospecific cues.

[Daniel Powell @Daniel_L_Powell]

Very happy to have this work out in preprint!

With lots of hard work from @A_a_ronRose and @GilRosenthal!

[Daniel Powell @Daniel_L_Powell]

Here we show that exposure to sublethal concentrations of calcium hydroxide cause female Xiphophorus birchmanni to prefer olfactory cues from males of the sister species X. malinche over conspecific cues. An effect that lasts more than two days but less than than ten

[Daniel Powell @Daniel_L_Powell]

We then show that raising the pH using sodium hydroxide has a similar effect, but increasing the Ca++ ion concentration using an equimolar concentration of CaCl2 reduces conspefic mate preference but does not cause the same flip in valence.

[Molecular Ecology @molecology]

QTL mapping and gene expression responses to thermal stress reveal a genetic association between hybrid ancestry and breakdown in thermal tolerance, suggestive of ecological incompatibility between two swordtail fish species.
