DOI: 10.1002/arch.21614
Abstract: Histone acetylation is an evolutionarily conserved epigenetic mechanism of eukaryotic gene regulation which is tightly controlled by the opposing activities of histone acetyltransferases (HATs) and histone deacetylases (HDACs). In insects, life-history traits such as longevity… read more here.

DOI: 10.1007/s10886-017-0908-y
Abstract: Within a species, individual animals adopt various defensive strategies to resist natural enemies, but the defensive strategies that are adopted in response to variations in predation risk are poorly understood. Here, we assessed consecutive foraging… read more here.

DOI: 10.1016/j.jinsphys.2017.06.008
Abstract: Many aphid species switch reproductive modes seasonally, with the sexual generations appearing in autumn. Sexual generations are induced by short days. It has been reported that the appearance of sexual morphs is suppressed by a… read more here.

Context‐dependent vertical transmission shapes strong endosymbiont community structure in the pea aphid, Acyrthosiphon pisum
Sign Up to like & getrecommendations! Published in 2018 at "Molecular Ecology"
DOI: 10.1111/mec.14449
Abstract: Animal‐associated microbiomes are often comprised of structured, multispecies communities, with particular microbes showing trends of co‐occurrence or exclusion. Such structure suggests variable community stability, or variable costs and benefits—possibilities with implications for symbiont‐driven host adaptation.… read more here.
