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.

Telomere dysfunction impairs intestinal differentiation andpredisposes to diet-induced colitis

This study shows that telomere shortening impairs intestinal differentiation, leading to barrier defects and diet-induced colitis through microbiome modulation and nutrient flux.

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.

Sexual conflict drives micro- and macroevolution of sexual dimorphism in immunity

This study shows that sexual conflict influences sexual dimorphism in immunity through molecular and phenotypic changes in seed beetles.

Elevated temperature increases genome-wide selection on de novo mutations

This study shows that rising temperatures increase genome-wide selection on mutations in ectothermic organisms, with potential implications for genetic diversity and evolution under climate change.

Sexual selection and the evolution of male and female cognition: a test using experimental evolution in seed beetles

This study tests how sexual selection affects cognition in seed beetles by evolving lines under monogamy or polygamy and measuring learning in mating and host search tasks.
