Emperor Penguins’ numbers dwindled in last Ice Age Cold
This has come as a rude shock to many scientists who have been working in the field. Researchers have been taken aback by coming to know that the last ice age actually destroyed Emperor Penguin populations.
Earlier they thought that emperor penguins would have benefited and prospered with higher amount of ice in their habitat. They thought that with more ice they would have bigger place to breed. But this was not the case as the study claims that their numbers went down drastically by the last ice age.
Researchers are both amazed and excited with the latest finding. Lead author of the study Jane Younger, a Ph.D. scholar associated with the University of Tasmania while detailing the findings of the study says that looking at how climate changes have impacted the penguin, which is taller and heavier than any other penguins, it seems amazing that they were impacted badly by ice age.
Researchers say that they concluded after analyzing how the genes are different in modern and ancient penguin populations. They claim that after studying it closely they were able to understand that Emperor penguin numbers started going up some 12,000 years ago as temperatures went up by about 15 degrees Celsius and the sea ice around Antarctica began to subside.
They claim that this may be due to the fact that emperor penguins have better survival chances in warmer atmosphere.
