Embryonic Diapause

Over 52 weeks I will be learning all about how to live and work creatively. My teachers are Aussie birds and animals. It is week seven and the creative force has produced the Kangaroo to build on the lessons that Australian birds, animals and habitat have been initiating.

Embryonic diapause (also known as delayed implantation in mammals) is the developmental arrest of a fertilised embryo. This evolutionary device, which has evolved in over 100 mammals, allows reproduction throughout the year and maximises survival of young during less favourable environmental conditions. An embryo is considered to be in diapause when mitosis is decreased or has stopped completely and considered to begin development again when mitotic activity reoccurs. There is a complex interplay of stimuli which regulate the entrance into and exit from diapause, but in marsupials it is very much dependent on a suckling young being in the pouch. The main benefit of embryonic dipause is to lengthen the active gestation period; regardless of mating seasons, birth can happen at the optimum time for the species, or to effectively space out births.

Kangaroos have a particular ability to delay the growth of their young through a process known as embryonic diapause.  This is a very adaptive way with which they are able to slow the growth process of their young ones when there is not enough source of food in the area where they are located.  Kangaroos communicate through various bodily movements such as touching, stomping their feet, grumbling and snapping.

♣ The lesson of kangaroo is that things can grow by delay! Is there a project you have in embryonic diapause, waiting for the right time to be kick-started again, waiting to be born at an optimal time?
