Australia: significant rate sex change:
Australian scientists have documented a surprising rate of sex change in wild birds. Nevertheless, a phenomenon that could be explained by growing pollution or other environmental triggers.
A study relating to five common Australian species. Consequently. However. including Kookaburras, Pies and Loricts, revealed that around 6% of birds presented the chromosomes of one sex, but the reproductive organs of another.
The results have shown that a surprisingly high number of birds had changed sex after birth. Similarly, researchers from the University of Sunshine Coast (Australia) said.
“This indicates that the determination of sex in wild birds is more fluid than what we thought.. can persist until adulthood,” said Dominique Potvin, co -author of the study, who carried out DNA tests on nearly 500 birds.
The vast majority of sex changes australia: significant rate sex change new australia: significant rate sex change new involved genetically female birds developing male gonads.

“We also discovered a genetically male kookaburra which was reproducingly active with large follicles. a dilated oviduct, indicating a recent production of eggs,” said Ms. Potvin.
The change of sex is known in certain species of reptiles. fish, but it is believed that it remains rare in birds and mammals.
Scientists had already documented sex changes in frogs induced by pollutants or warmer temperatures.
But the cause of sex changes in wild birds is not yet clear. indicates the report of the University of Sunshine Coast.
The phenomenon could be due to environmental factors, such as the accumulation of hormonal disturbing chemicals in wild areas.
“Understanding how. why the change of sex occurs is vital for conservation. to improve the precision of research on birds,” added Ms. Potvin.
The study was published australia: significant rate sex change new this week in the scientific journal australia: significant rate sex change new with Biology Letters. Reading Committee.
