The first animals to live on land were tiny arthropods, escaping predators and eating food in fields of cooksonia plants.

Hey #ESEB2025 folk! I'll be presenting my work on describing evolution in finite populations at 11:30 am on Tuesday in S-03. Drop by to learn how taking ecology and variable population size seriously changes classic pop gen descriptions like the Price eqn, revealing novel directional eco-evo forces.

Stochastic differential equations for trait frequencies, mean value of a trait, and the variance of a trait in the population

hello to everyone going to #ESEB2025! want to hear about the consequences of age-dependent plasticity in reproducing via sex vs. asex? I will give a talk at 11:15am on Thursday in S15.02. come for the pretty Hydra illustrations, stay for the novel evolutionary insights on facultative sex!

Thanks, Hanna! There are quite a few Kokkonuts at #ESEB2025! On Thursday, @gauravathreya.bsky.social talks about ageing + sex, @tomospotter.bsky.social talks about guppy polymorphisms, @ccrowther.bsky.social has a poster on nesting 🐢, and Victor Ronget has a poster on ageing trends in mammals + 🐦!

Hanna Kokko @kokkonut.bsky.social · Aug 19

#ESEB2025 Very concentrated looks when @shikharabhat.bsky.social educates us about pop noise! One of the last talks I could attend, sorry I had to leave early (planned, still 🫤) The lab's presence continues without me so grab them for a science chat!

Two other members of the research group have successfully made it to @eseb2025.bsky.social ahead of me.

Look out for @kztwyman.bsky.social, whose poster "A formal theory of group-level adaptation for obligate eusociality" (P01.068) is in this evening's session.

And Chedhawat Chokechaipaisarn, whose poster "The consequences of constrained sex allocation under local mate competition" (P02.036) is in Tuesday's session.

This is based on his recent paper in Journal of Evolutionary Biology:

New paper: "The consequences of constrained sex allocation in diploids and haplodiploids under local mate competition", with Chedhawat Chokechaipaisarn:

doi.org/10.1093/jeb/...

@jevbio.bsky.social

Figure 1. Unbeatable sex allocation strategy of unconstrained females (r*) as a function of proportion of constrained females (p) under local mate competition with two foundresses colonising the patch. Shown are the result for Godfray’s (1990) erroneous diploidy solution (dashed grey line), our corrected diploidy solution (solid grey line), and our haplodiploidy solution (solid black line). Overlaid are results from individual-based simulations (discs).

There could be some physiological constraints for key structure to develop, e.g. the wings. So there could be a minimum duration, but I would suppose that varies across different animal groups. For the second questions, again, I don't know. But these are fun questions! (2/2)

Bing Dong董冰 @bingdongevo.bsky.social · Jan 15

Thanks! These are really interesting questions. To be clear, my study only looks at the starting time, or onset, of metamorphosis. If you are talking about the duration of metamorphosis, well, I don't know. (1/2)
