Emperor penguins are not only the largest species of penguin in the world but also one of the most unique. They are very social, living in colonies that can include hundreds of thousands of individuals. Nevertheless, emperor penguins are monogamous. Having selected a mate, emperor penguins remain faithful to each other for life, using vocal calls to find one another when they return to their breeding site on the compacted ice of the Antarctic continent. It is believed that different frequencies alert mates to the sound of their partner’s call.
Another interesting aspect of emperor penguins is that they return to the same site, called a rookery, to nest each year. Although their path to the rookery is different every year due to the shifting sea ice, in general, the penguins continue to use the rookery where they were hatched. Their loyalty to a particular breeding ground results in increasingly larger penguin colonies, some with more than a million birds. Males tend to arrive first to reestablish and defend their preferred nesting sites and females return a day or so later.
Emperor penguins are not considered endangered and are not currently protected under international law. In fact, in areas where reliable population counts have been conducted, the evidence suggests that populations are stable. However, due to harsh environmental conditions, some colonies have not been monitored on a consistent basis. Estimates of population sizes are at about 240,000 breeding pairs. Taking into consideration the non-breeding birds as well, the total translates into about 600,000 adult birds. Emperor chicks that reach adulthood can survive for 20 years.Summarize the main points in the lecture, and then explain how they cast doubt on the ideas in the reading passage.
Due to the given lecture, the professor claimed that the all three assumptions mentioned in the passsaged regarding to the new research are incorrect now.
First it was said in the passage that the emperor penguins are monogamous. But the most recent research have proved that they are serially monogamous. Means that they are mating each season and they are loyal and deligant to the mate for carying the chick till they return and if they don't locate the perivious mate during the mating season which is most likely and contrast happens only 15% of the times they mate again.
Secondly in addition to the passsage each season they return to a same nesting location but university of minestan published a research in which they used satelite pictures to see whether the claim is true or not but the reasuls showed that in six instances they don't return. And it is confirmed that they find new rookery for nesting.
At last but not least they have stimitaited that the emperor penguins population could decline to one third of the current population till the end of this centry. Because of the enviromental changes such as melting the ice in polars they are now concidered as one of the endanger spicies.
