Nice new life-history trade-off paper out soon from @katelaskowski.bsky.social & team. Meta-analytical confirmation of the missing (yet much invoked) -ve genetic covariance. In a 'resource allocation trade-off' world, genetic variation within pops may lie more in resource acq than allocation. Cool.
What's the meta-analytic evidence for life-history trade-offs at the genetic level?
Understanding the evolutionary mechanisms underlying the maintenance of individual differences in behavior and physiology is a fundamental goal in ecology and evolution. The Pace-of-life syndrome hypo...

Hi there - thanks a lot for running this feed. Please could I be added? I'm an evolutionary biologist at University of Exeter, UK...

Thanks!

3/3 Why cool? Means helpers in cooperative breeders (e.g. us) could have cryptic maternally-mediated beneficial effects on pre-natal development of young. Our data implicate help not group size effect as mat reaction norms to *female* helpers, who work twice as hard as males (tinyurl.com/38kv8jp2)

2/3 We show helpers reduce mum's post-natal workload (see pic) – may allow mums to invest > in egg (which only mums can do). And/or: We know helpers increase overall nestling feeding rate (tinyurl.com/38kv8jp2) - may increase mum's benefit from investing in the egg. Or: not adaptive (modest effect!)
Maternal reaction norms to female helper numbers. With increasing female helper numbers, mothers increase their egg size but decrease their chick feeding rates.

*New #evolution paper* Sparrow-weaver mothers lay larger eggs when they will have more help feeding the resulting chicks. Maternal reaction norms to help are *opposite* for egg size & nestling feeding rate. Cool. But why do this? 1 of 3... Fine work @p_capi on X. tinyurl.com/2djsp6zd #ExeterCEC 🌍🧪🦉
Sparrow-weavers! A dominant breeding pair on the left (male has dark bill, female pale bill, in this subspecies). They can have up to 10 non-breeding adult helpers in their cooperatively breeding family. And a brood of three chicks on the right. Photos my own.

#HiSky! My lab study Social #Evolution & Senescence in families via..
- Fieldwork on birds (Kalahari weavers) & mammals (badgers)
- Single-cell res studies of #microbes
We dig unicellular #ageing, parental age effects, #inflammaging, #cooperation in variable enviros, social plasticity 🌍🧪🦠 #ExeterCEC
Our main fluffy study organisms - white-browed sparrow weaver & European badger. Photos my own.

Hey Steve - v cool! Will use in my nervous system evolution lectures : ) Was hunting in the paper for a neat plot of the data showing gymnogenes as an outlier. I see that I can make one from S1b table, but thought I'd ask in case you have a flashy one from the original submission. Thanks!

Thanks B! #evolsky you say. I need to get dialled in to some of that!
