Phenological responses of Pseudomallada (Neuroptera: Chrysopidae): Comparative data from three Nearctic species and interspecific hybrids

European Journal of Entomology, 2015
Three Nearctic species - Pseudomallada macleodi (Adams & Garland), P. perfectus (Banks), and P. sierra (Banks) - share a suite of phenological characteristics with their Western Palearctic congeners. They overwinter as free-living larvae (primarily third

Molecular Regulation of Paused Pluripotency in Early Mammalian Embryos and Stem Cells

Frontiers in Cell and Developmental Biology, 2021
The energetically costly mammalian investment in gestation and lactation requires plentiful nutritional sources and thus links the environmental conditions to reproductive success.

Transcriptional Regulation of Reproductive Diapause in the Convergent Lady Beetle, Hippodamia convergens

Insects, 2022
Diapause is an alternate development program that synchronizes an insect’s life cycle with seasonally abundant resources and ensures survival in unfavorable conditions.

Two distinct aphid diapause strategies: slow development or development arrest

Journal of Insect Physiology, 2023
Aphids adapt to unfavourable environmental conditions, such as low temperatures in winter, by laying diapausing eggs that overwinter. Diapause is a stress-resistant and developmentally arrested stage that can be adopted in order to increase the chance of survival in adverse environmental conditions.

Differences in the Development of Internal Reproductive Organs, Feeding Amount and Nutrient Storage between Pre-Diapause and Pre-Reproductive Harmonia axyridis Adults

Insects, 2019
Diapause control is one of the successful methods for long-term cold storage of biological control organisms without decreasing their fitness. Sufficient preparation before diapause is essential for successful diapause initiation and maintenance ...

Comparisons in temperature and photoperiodic-dependent diapause induction between domestic and wild mulberry silkworms

Scientific Reports, 2021
The bivoltine strain of the domestic silkworm, Bombyx mori, has two generations per year. It shows a facultative diapause phenotype determined by environmental conditions, including photoperiod and temperature, and nutrient conditions during embryonic ...

Seasonal and geographical adaptations in the parthenogenetic stick insect, Ramulus mikado (Phasmatodea: Phasmatidae)

European Journal of Entomology, 2022
Seasonal and geographical adaptations in terms of obligatory embryonic diapause in the parthenogenetic stick insect, Ramulus mikado, were studied. First and second instar nymphs were collected at locations at three latitudes in Japan and reared in the ...

Temperature-induced embryonic diapause in chickens is mediated by PKC-NF-κB-IRF1 signaling

BMC Biology, 2023
Background Embryonic diapause (dormancy) is a state of temporary arrest of embryonic development that is triggered by unfavorable conditions and serves as an evolutionary strategy to ensure reproductive survival.

Cell cycle dynamics during diapause entry and exit in an annual killifish revealed by FUCCI technology

EvoDevo, 2019
Background Annual killifishes are adapted to surviving and reproducing over alternating dry and wet seasons. During the dry season, all adults die and desiccation-resistant embryos remain encased in dry mud for months or years in a state of diapause ...

Molecular Regulators of Embryonic Diapause and Cancer Diapause-like State

Cells, 2022
Embryonic diapause is an enigmatic state of dormancy that interrupts the normally tight connection between developmental stages and time. This reproductive strategy and state of suspended development occurs in mice, bears, roe deer, and over 130 other ...
