i made a new framework for modelling stochastic eco-evolutionary dynamics of multivariate traits !!

the finalized version is live !

[ in case you prefer oup's formatting over mine ;) + we fixed couple typos below eqn ten :B ]

In community ecology, this is called the "Appendix XVII of a Peter Abrams paper" effect

Interested in host-associated microbiomes? Attending @eseb2025.bsky.social? Then come check out Symposium S07 on Monday August 18th and hear all about how microbiomes contribute to adaptation. Gut microbiomes, climate change, thermal physiology, behaviour, invasion biology, blood-feeding, and more!

hey eseb ppl check out toms talk !

What if your family members turn out to be your worst enemies? Come see my talk at #eseb2025 on using pedigree and mark-recapture data to explore how relatedness structures competitive interactions, and whether this maintains variation! Thursday, 11am, S48.02, meeting room 122+123
The title slide of the talk I'll be giving. It reads: Are mitochondrial sisters their own worst enemies? Testing for negative frequency-dependent selection via resource competition in Trinidadian guppies. There is a depiction of a guppy family tree.

hai eseb people ! come to my talk introducing the quantitative genetics of microbiome mediated traits :) 2:30-2:45 at S07.02

btw our ppr just got accepted at evolution ! amazing and challenging reviews ::)) revised pre-print here

Quantitative Genetics of Microbiome Mediated Traits
Multicellular organisms host a rich assemblage of associated microorganisms, collectively known as their “microbiomes”. Microbiomes have the capacity to influence their hosts’ fitnesses, but the condi...

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.
An illustration with populations on the left and mathematical representations of these populations in terms of birth-death processes on the right Stochastic differential equations for trait frequencies, mean value of a trait, and the variance of a trait in the population

im not advocating ai slop . this really shouldn't be a concern anyways . most papers are terribly written , so our filters should be well trained to exclude all slop . we have little to lose and so much to gain from adopting ai assisted writing . seems pretty obvious to me !

scientific vernacular and grammar is algorithmic . llm's are language calculators . lets embrace that to make our fields more inclusive and also not waste precious time and creative energy . lets not play the same game that was played when hp and ti replaced slide rules

aso ! time to get a virtual machine running !!

the biggest question i have (aside from the haze of political/cultural turmoil) is ... what software is Bob Holt using for his presentations ??

shares the aesthetics of a theoretical ecology book published around the time jurassic park came out - purple background (pseudo papyrus font?) - legendary

happy priiide !!

but the framework can be used to formally obtain all sorts of novel models (eg, evolutionary rescue and coevolution) and provides a useful direction for understanding the relationship of multivariate traits and eco-evolutionary processes !!!

i was motivated by studying G-matrix evolution , and found drift tends to drive trait correlations to their extremes despite commonly held wisdom that drift merely tends to scale G-matrices !!
trait correlations evolving in response to drift . they wiggle a lot but ultimately veer off towards plus or minus one
