An article of the ENN, the enviromental news network, from the 18th of February says that a huge Adélie penguin colony which lives in the Commonwealth Bay is about to die due to an iceberg which is blocking their way to the Antarctic Sea to get food. The iceberg which is known as B09B has been there for about six years now stucked and caused that the size of this colony is decreasing rapidly. The way around is 40 miles and the most penguins can't make this way frequently enough to feed their offsprings or even themselves. It has been a strong and big colony for a long time already, but now the iceberg from the size of Rome could cause their complete destruction from this area. The size of the colony has been recorded for over 100 years now and Sir Douglas Mawson coplained already about the noise of the around 100,000 penguins. Chris Turney, professor of climate's change and earth sciences at the UNSW, says that today "It's eerily silent." The colony shrinked to a size of about 18,000 peguins while it used to be 160,000 back in 2010.
The Adélie penguin in its natural enviroment
The big problem is that because of those massive abiotic change all heterotrophs which are mainly penguins in this region don't have access to the sea to catch fish. Due to this fact the population of the penguins is in a massive danger. If they would die off this could cause troubles for other heterotrophs in the community. Especially Seals would be taken a important source of food and their population in this area could be in danger as well. The change of the abiotic factor would probably have bad consequences for the biotic factor in the form of the loss of the penguin species for the comunity.

In the polar regions are autotrophs very rare and often even not existing because there is only half a year light so it is important to have a healthy heterotroph population to guarnantee the interbreeding of species due to enough food. If this would happen the area in which the penguins are living at the moment would become an unsustainable community.
Calm, majestic and still responsible for the genocide of a whole population.
