Ryan Weaver

A group of us went to our Senators' regional offices this morning, met with the Regional Directors. They were engaged and know the importance of research (in general terms). However, they did not seem to know about what is going on currently (re: F&A). If you can make a similar trip - please do.

...and every college professor needs to take.

I would liked to be added, please!

I am hiring a postdoc to work on evolutionary genomics projects with maize and its wild relatives. This is part of a broad collaborative project known as CERCA that aims to improve maize with adaptations from the wild. Please share or consider applying!

+1 'for don't call it moots', but also I grow brine shrimp and Tigriopus copepods and think about them sometimes.

I see a lot of potential using this in a mitonuclear context. Very nice work!

Oooh, I look forward to reading this!

Yeah, maybe heteroplasmy of mitos and the oogenesis bottleneck still allows for the light of selection to shine on bad mitogenomes. Not the case in Y?

.... because mito genome products must closely interact with nuclear products for mitos to function. So, mitonuclear coevolution and selection for functional mitochondria.

I don't think about Y much, but are they still thought to mostly be degenerate?

Our review paper on the stunning variation in sex roles and mating systems in shorebirds is published in Ibis and freely available to all.

Shorebirds have provided so much insight into this topic, but their potential is still untapped and there is much left to learn!

I'm Ryan Weaver (EEOB, Iowa State University). I am recruiting PhD. students to work on topics related to mitochondrial evolutionary bioenergetics. Potential projects include mitonuclear coevoution and the bioenergetic basis of pathogenicity of animal-infecting fungi, among others.

Here are the instructions I gave. I used the custom instructions section in GPT to try to control how it behaved. We used GPT3.5 since its free, but I think 4.0 would have performed better. GPT3.5 was kind of a pushover, confidently agreeing with incorrect answers and carried those mistakes forward

Note to self that if you give 54 students in your evolution class prompts to have ChatGPT create Hardy-Weinberg equilibrium problems to answer and have a conversation about, YOU will have to do 100s of HWE problems 🥲 #AcademicSky #evobio

In addition to clarifying presence/absence in some taxa, we found putative cases of horizontal AOX transfer from fungi and protists to some animal taxa. We’re working on the why, but the hgt AOX taxa tend to inhabit hypoxic environments, a potential role for AOX to maintain mito function.

AOX is an alternative to complex IV, which is a terminal oxidase. AOX provides metabolic flexibility for when conditions disrupt CIV function. E.g. hypoxia, redox stress. We show it is present in extant proteobacteria, the group thought to be the source of mitos in eukaryotes, but not other bacteria

We have a new paper out on the taxonomic distribution of an understudied aspect of mitochondrial physiology, the alternative oxidase AOX.

The roles mitos play depend ultimately on managing electron flow through the electron transport system to reduce O2 to H2O.

Do you have an undergrad or masters student in your lab applying to grad school? Encourage them to submit an application to Stanford's Biology preview program by Friday! Application takes <30 minutes. Program features 1:1 mentorship, fee waivers, practive interviews & more: forms.gle/phtT9Kfe1MkH...
