A week left to apply for this postdoc! Join me in sunny (ish.. for now..) Stockholm to work on this ERC funded project exploring the intersection of sexual selection and epidemiology. We'll use guppies & worms, experimental epidemics, AI tracking, modelling, fieldwork su.varbi.com/what:job/job...

Differences in Parasite Infection Status and Behavior Between a Clonal Fish and Her Sexually Reproducing Heterospecifics
We found that Amazons and Sailfins differed in their qualitative, but not quantitative, resistance to parasites. Amazons had worse qualitative resistance (i.e., were more likely to be infected with a...

Pace of life shapes parasite defense. Fast living guppies invest less in resistance and fecundity tolerance but not mortality tolerance. Now out in Evolution Letters, by Sadie Evanov and @jfstep.bsky.social doi.org/10.1093/evle... Image Credit: J Mank

I'm looking for a lovely, talented PhD student, working on my ERC-funded project investigating the links between sexual selection and epidemic dynamics. The project uses guppies, worms, behaviour tracking, big experiments, and maths.. email me! Must have a masters! su.varbi.com/what:job/job...

Looking for a postdoc to work with existing SNP data from parasites of guppies across Trinidad. How do river structure, host specialisation, and host behaviour structure parasite population genetic structure and evolutionary potential? Join me in Stockholm! Email me :D su.varbi.com/what:job/job...
