Size‐selective mortality evolutionarily alters collective behaviour in response to predation risk in a zebrafish (Danio rerio) harvest‐induced selection model

Journal of Fish Biology, EarlyView.
Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

Cytochrome P450 1a (CYP1A)‐Knockout Javanese Medaka Fish Exhibit Diabetic Traits and Reduced Reproductive Capacity

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Analyses of cytochrome P450 1a (CYP1A)‐knockout (KO) Javanese medaka (Oryzias javanicus) revealed that CYP1A is involved in glucose regulation and reproduction. In the KO fish, significant increases in hepatic transcripts of insulin, glucagon, and somatostatin genes, as well as elevated blood glucose, liver mass, and liver triglyceride levels ...

Epigenetic Aging in Brain Tissue of the Self‐Fertilizing Vertebrate, Kryptolebias marmoratus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Using the self‐fertilizing vertebrate Kryptolebias marmoratus, we developed an epigenetic clock from brain tissue that predicts chronological age with high accuracy, demonstrating that DNA methylation changes consistently with age even in the near absence of genetic variation. The 40 age‐associated CpG sites identified map to genes with conserved roles
