The climate changes and its repercussions are becoming more and more evident with each passing day. Different species are learning to live with these changes. This fact has been epitomized by a research study on Emperor Penguins who were found to be adapting fast to the changing climate. The study was carried out by researchers at the University of Minnesota.
The study was conducted over a period of three years and the researchers found that the Penguins had six instances of changing sites where they would eventually breed.
It was a common belief that Penguins stuck to their breeding sites. However recent satellite imagery has revealed that the Emperor Penguins are not returning back to the spots where they were breeding.
Lead author Michelle LaRue said “Our research showing that colonies seem to appear and disappear throughout the year’s challenges behaviors we thought we understood about emperor penguins. If we assume that these birds come back to the same locations every year, without fail, these new colonies we see on satellite images wouldn’t make any sense. These birds didn’t just appear out of thin air—they had to have come from somewhere else.”
The conclusions of the study were presented by lead author Michelle LaRue at the IDEACITY conference in Toronto and the study will be published in the Ecography journal. The researchers have gleaned the information that penguins are moving from colonies to colonies and the team intends to continue research as to why they do it.
Satellite imagery has been a great boon in the study of Emperor Penguins in Pointe Géologie which once had a thriving Penguin population but is now believed to be falling. The latest findings are an aberration in the normal pattern of behavior and have led the researchers to rethink on how they construe these fluctuations
