Assessment of the volatility and thermal stability of chemicals that stimulate females of Moina macrocopa (cladocera) to produce diapausing eggs

The volatility and thermal stability of chemicals that are contained in the metabolic products of Moina macrocopa females that stimulate the production of diapausing eggs in these females have been studied in experiments with separately cultivated individuals. It has been shown that the gametogenesis-stimulating chemicals in this species are nonvolatile compounds: the effect of the medium that contains the metabolic products of the organism was not decreased after many hours of blowing with argon. Prolonged heating up to 80°C also did not deactivate the ability of these products to change the reproductive mode. The effect of the medium that contains these products decreased after boiling, but if the possibilities of their oxidation or binding with salts of metals were excluded, they retained the ability to change the reproductive mode of the animals even after boiling. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

The volatility and thermal stability of chemicals that are contained in the metabolic products of Moina macrocopa females that stimulate the production of diapausing eggs in these females have been studied in experiments with separately cultivated individuals. It has been shown that the gametogenesis-stimulating chemicals in this species are nonvolatile compounds: the effect of the medium that contains the metabolic products of the organism was not decreased after many hours of blowing with argon. Prolonged heating up to 80°C also did not deactivate the ability of these products to change the reproductive mode. The effect of the medium that contains these products decreased after boiling, but if the possibilities of their oxidation or binding with salts of metals were excluded, they retained the ability to change the reproductive mode of the animals even after boiling.
