Immune and DNA repair gene activity differs by sex in seabirds
A cross-sectional study of 16 male and 16 female Scopoli’s shearwaters found sex-linked gene-activity patterns across younger and older adults.A cross-sectional study of 16 male and 16 female Scopoli’s shearwaters found sex-linked gene-activity patterns across younger and older adults.

Who was studied32 breeding Scopoli's shearwaters, against females
What changedMales had higher DNA repair gene expression than females, while females shifted from immune to stress pathways with age
The catchThe sample comprised only 32 breeding birds from one colony
