15 years. 1,100 adults. 3,400 juveniles. One question: do immigrants pay a fitness cost in the wild?🐟 Yes, but only sometimes. The cost of dispersal in Atlantic salmon depends on the origin, sex and age. Out now doi.org/10.1098/rspb... in ProcB @royalsocietypublishing.org 1/4

Emilio Egal’s first PhD paper on the effects of dispersal on fitness in wild Atlantic salmon, using a 15-year genetic pedigree comprising more than 1,100 adults and 3,400 juveniles! @inrae-france.bsky.social @inrae-ecobiop.bsky.social @cbgpmontpellier.bsky.social @ofbiodiversite.bsky.social

I had the pleasure of presenting my research on "Reproductive success of immigrants depends on the population of origin in Atlantic salmon" at the ESEB Congress 2025 in Barcelona @eseb2025.bsky.social @eseb.bsky.social Thanks to the organizers and to all participants ! #ESEB2025
