Annual Review of Physiology, 2000
▪ Abstract Embryonic diapause, or delayed implantation as it is sometimes known, is said to occur when the conceptus enters a state of suspended animation at the blastocyst stage of development. Blastocysts may either cease cell division so that their size and cell numbers remain constant, or undergo a period of very slow growth with minimal cell ...

Annual Review of Entomology, 2014
Diapause, a dominant feature in the life history of many mosquito species, offers a mechanism for bridging unfavorable seasons in both temperate and tropical environments and serves to synchronize development within populations, thus directly affecting disease transmission cycles.

Transgenic Research, 2017
Diapause is a state of developmental arrest that is most often observed in arthropods, especially insects. The domesticated silkworm, Bombyx mori, is a typical insect that enters diapause at an early embryonic stage. Previous studies have revealed that the diapause hormone (DH) signaling molecules, especially the core members DH and DH receptor 1 (DHR1)

Bulletin of Entomological Research, 2001
AbstractDesiccation resistance was examined in pre-diapause, diapause and post-diapause larvae of the spruce budworm, Choristoneura fumiferana (Clemens), in terms of passive water evaporation under three desiccation conditions: freeze-drying, desiccant-drying at 2°C and desiccant-drying 18°C.

Diapause and diapause dynamics of Colias alexandra (Lepidoptera: Pieridae)
Oecologia, 1982The mechanisms and adaptations involved in the "obligate" third instar larval diapause of Colias alexandra, a native Rocky Mountain and intermountain region butterfly, are examined. Generally univoltine throughout its distribution, scattered, isolated bivoltine populations occur.

Embryonic diapause in vertebrates
Journal of Experimental Zoology, 1993AbstractEmbryonic diapause occurs in many species of vertebrates, but the physiological mechanisms which control this fascinating process are exceedingly different in the diverse groups which employ this reproductive strategy. In nonmammalian species and some bats, reduction in rate of embryonic development is temperature dependent, but this is not the

Diapause in Monogonont Rotifers
Hydrobiologia, 2005This review focuses on more recent findings on the diapause in Monogonont rotifers, since the major reviews by Pourriot & Snell (1983, Hydrobiologia 104: 213–224) and Gilbert (1992, Rotifera. In Adiyodi, K. G. & R. G. Adiyodi (eds), Reproductive Biology of Invertebrates, Vol. 5 – Sexual Differentiation and Behaviour. IBH Publishing Co., Oxford: 115–136;

Embryonic Diapause and Maternal Recognition of Pregnancy in Diapausing Mammals
2015The dynamic nature of early embryonic growth is at odds with the phenomenon of mammalian embryonic diapause, because embryos in diapause are in a state of suspended animation of varying duration. The signals that control embryonic diapause differ between species, but in all cases, it acts to synchronise reproduction with external factors to maximise ...

Diapause and Estivation in Sponges
2009Sponges can be found in fresh or saltwater habitats. As part of their life cycle, many sponges produce gemmules as a means of surviving environmental challenge. In most sponges, the gemmules contain cells that are initially in a state of metabolic arrest that is controlled by endogenous factors. This state is known as diapause.
