Finally! The defense recording is live! I keep looking at it and wincing, because watching myself speak is the most awkward thing ever, but @MaxRLambert said I should and hey, the upside of virtual defenses should be being able to show everyone, right? https://t.co/uL1YjEMm5T

#SICB2023 authors, please consider uploading recordings of your talks and posters to SICB+! I have seen so many great talks I would love to show to colleagues who couldn't make it to the meeting in person. I'm so grateful so many people have told me they're planning to upload!

On my way back home from #SICB2023 and I am so grateful for all the wonderful connections I made and having the opportunity to tell everyone about zebra finch reproductive trade-offs!

I meant to go to bed early so I could be up to see the #SICB2023 talks tomorrow but the politics are just too fuckin entertaining 🍿

Adding heating pads created 7/10 asynchronous nests; unheated control beats still hatched 3/10 asynchronous nests. (One of those is just "there was only one hatchling," which I would not be surprised by either--climate changed temperature and weather shifts are often variable!)

Well, if you have a bunch of siblings that are suddenly developing at different rates, that introduces a new and totally chance based axis of variation. What happens if we use heat packs to do that on purpose? Collected mass, limb lengths, blood samples.

#SICB2023 talk from @_stans96: because birds usually manage synchronous hatching by not brooding until full clutch is laid, climate change can throw some interesting wrenches into the mix. Higher ambient temperatures can start incubating first laid eggs well ahead of schedule!

After Pd infection, metabolic savings with torpidity vary considerably with ambient temperatures. If the minimal temperature the bats can tolerate has shifted to be warmer, that... puts them right in the middle of Pd sweet spot!

#SICB2023: from @MollySimonis, big brown bats are an interesting case study for torpidity research because they are prone to long term (>10 yrs!) infections with invasive pathogenic fungus Pd. Pre-infection Pd with continuous ambient temperatures preexisting in the lit.

NB: she's on the job market; @emilyjanedennis are you still looking for postdoc applicants? I don't think she's on Twitter but I see a lot of nice parallels with Emily's work.

Seminatural mice were born in the lab and acclimated in the enclosures for 6mo before measurements were taken. "We wanted to capture wild mice and introduce them into the semi natural enclosures, but we couldn't get IACUC approval for that because they are very, very dirty."

Mitochondrial performance is more complex: lab and wild have significantly lower respiration than seminatural! Wild mice also had higher liver respiration than the other two. For some things, seminatural enclosures really help! .... But not so much for mitochondria, alas.

Holy crap she took SO MANY msrs of condition, metabolism and energy balance from mice in three populations in her enclosures. What a data set! Lab mice have significantly less grip strength, higher hematocrit & RMR than wild mice; semiwild mostly mice cluster with wild mice.

#SICB2023: Kaylene Yamada discusses strengths and weaknesses of studying behavior in lab and field. Useful examples of phenotypes that are not visible in the lab, but immediately become apparent in natural or seminatural environments! Focus: Peromyscus. I love this kind of work.

#SICB2023: Shayne Halter finds that torpor allows hummingbirds to save energy and reduce body mass loss, ESPECIALLY for smaller birds. Smaller birds are more likely to go into torpor. Torpor frequency vanished as birds got larger within a species.

Fun time at @SICB_ 2023 conference to present my work on Binaural hearing of small mammals. I am honored to be selected for the @SICB_ Professional Development Award. Thanks to my mentor @ZaarlyLiz , @IntegrativeBIOL ,and all the co-authors.

In meta analysis, study, spp, and tissue type explain very little variation in results. The specific type of developmental perturbation doesn't seem to matter, but within a type of perturbation effects are strong and robust: mitochondrial parameters explain about 30% of var!
