Reposted by Ryota HASEGAWAHanna Kokko @kokkonut.bsky.social · 04/07/2025Is it stressful to be surrounded by infected individuals, even if you're not infected yourself? Might this even increase mortality (if others could have performed work but now won't)? Sounds plausible, but we don't have evidence from very many systems. Here's one! academic.oup.com/evolut/advan...academic.oup.comParasite prevalence in a social host has colony-wide impacts on transcriptional activity and survivalAbstract. Parasites pose significant challenges not only to individual hosts but also to entire social groups. We investigated the effects of parasitism by 04310 43
