Life-history adaptation under climate warming magnifies the agricultural footprint of a cosmopolitan insect pest

The paper models how climate warming affects insect pest life-history traits and agricultural impact using thermodynamics and life-history theory, finding increased pest damage under warming.

Coevolution of longevity and female germline maintenance

This study examines how germline maintenance varies with reproductive timing in seed beetles, finding that early-reproducing females show peak maintenance at youth while late-reproducing females exhibit the opposite pattern.

Heat stress reveals a fertility debt owing to postcopulatory sexual selection

This study shows that male fertility declines under heat stress when evolved under strong postcopulatory sexual selection, with similar effects observed in females, suggesting a fertility debt linked to sexual selection.

Increased male investment in sperm competition results in reduced maintenance of gametes

This study shows that male seed beetles under strong sexual selection produce lower quality offspring due to reduced germline maintenance, linking sperm competition success to increased mutation rates.

The mating system affects the temperature sensitivity of male and female fertility

This study shows that mating system influences thermal sensitivity of fertility, with females showing higher sensitivity than males, and this sex difference can evolve rapidly under sexual selection.
