“…Principal component analysis of gene expression profiles resulted in separation between the different morphogenetic cues and exposure times, and not only identified those genes involved in the early response but also those which influenced downstream biological changes leading to larval metamorphosis or settlement.…”

“…In the present study, potential batch differences in progeny survival of wild-caught, hatchery-spawned Faroe Bank cod (Gadus morhua L.) were investigated at two defined periods during early life history; i) the embryo stage (60 day degrees post fertilisation) and ii) the fry stage (110 days post hatch), post metamorphosis. The fry stage experiment was conducted in three replicates (N = 300 per replicate), and a panel of three polymorphic microsatellite markers was used for parental analysis. …”

“…The results suggest that miRNAs play important roles in the developmental transitions between the embryonic stages of development (starting with maternal loading), during which they might influence the germ-band type and metamorphosis mode. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this article (10.1186/s12864-017-4177-5) contains supplementary material, which is available to authorized users.…”

“…Whereas the effects of a deteriorating larval habitat (e.g. pond desiccation) on triggering an early metamorphosis have been extensively investigated in amphibians, the consequences of the resulting reduced size at metamorphosis on fitness in the post-metamorphic terrestrial stage remain poorly understood. …”

“…Although third-order changes may occur much later, preparation is critical because the first-order adoption and the second-order adaptation may form a basis for the third-order metamorphosis. We hope that this theoretical lens is useful in providing foresight for the changes in the nature of services in the post-pandemic. …”

“…Additionally, adults that developed from injured larvae had reduced lifespans, indicating that cellular and molecular mechanisms activated by blunt force injuries in larvae persist through metamorphosis and adult development. Previously, the HIT device has been used to investigate genetic and environmental factors underlying mechanisms that contribute to consequences of blunt force injuries incurred in adult flies. …”

Methods: We used functional genomics to derive genome wide profiles of methylated DNA and measured changes of gene expression after hormonal treatments of a highly responsive tissue, tailfin. …”

We then statistically explored whether pupal and adult body size, ornament size and/or ornament complexity are correlated with sex-specific development times. …”
