The life of ... an emperor penguin

Hello,

Today, we're looking at the fascinating lives of emperor penguins. These incredible creatures have adapted to survive in the extreme conditions of Antarctica, and in this post, we'll explore their incredible lives.

In late May to early June just before the Antarctic winter sets in, female emperor penguins lay a single egg. They then leave the colony and go on a two month hunt. The male rests the egg on his feet and covers it with warm, feathered skin called the brood pouch. He will eat nothing for these two months. The chick hatches in August and the female returned to take over. She has spent two months feeding and now regurgitates some food for the newly-hatched chick. The male leaves to feed himself as he has been living off his fat reserves for the past two months.

The female keeps the chick in her brood pouch until the sea ice close to the breeding site breaks up as the temperatures warm. The chick is now strong enough to learn how to swim and hunt for themselves. They will return in 5 years to rear their own chicks. Interestingly, 15% of adults will find the same partner from the previous year. We don't know how they recognise them, because there isn't a permanant nest or specific place for them to return to.

Emperor penguins survive the chilling Antarctic winds by standing close together in huddles. They take it in turns to be in the middle before moving back to the outside to allow another individual to warm up. Emperor penguins are amazing swimmers. In fact, they are the deepest-diving birds in the world, reaching depths of over 500m and staying under water for over 20 minutes. They feed on squid, krill and fish.

Emperors are classified as near threatened however, they face a couple of threats. They are eaten by orcas and leopard seals. However a much bigger and long term threat is climate change. As with most species in the Antarctic, climate change is a massive problem. Most of the food chain in Antarctica, relies on the sea ice. The sea ice that is now being rapidly reduced. Just this week, an article in ScienceDaily came out warning about a "Catastrophic Breeding Failure in Emperor Penguins", due to the loss of sea ice. Warmer water temperatures cause problems in fish migration and could lead to thousands of chicks starving each year or the females being too weak to produce eggs that actually have a chance to survive. So, as with all animals, humans are pushing a pretty stable and well adapted population ever closer to extinction.

The life of ... an alcon blue butterfly

Hi everyone, Today we are going to be looking into the life of an alcon blue butterfly (Phengaris alcon). After mating, the females lay their eggs on marsh gentian, a blue-coloured wildflower. The eggs can only be laid on these flowers, as this is what the newly hatched caterpillars will eat. Although in some alp regions, they can also be found on willow gentians, a close relative of the marsh gentian. Once the caterpillars have hatched from the eggs, their main predator and danger are the ants that swarm below. But high on their plant homes, the caterpillars are safe. However, this isn't where the alcon blue caterpillars are going to stay forever. Eventually, they drop down to the ground using silk strings. With no protection, they are soon dragged off by the ants. The most amazing part is, the alcon blue caterpillars give off the same scent and chemicals as the ant larvae. So the ants take the caterpillars back to their brood chamber, wher...

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back ...

Some info, resources & solutions to the plastic crisis

Hello Everyone, Plastic was once a miracle material but now it is the enemy. And we are the last generations who can do anything about it. If we want future generations to experience the world in all its amazing beauty like we have: we have to make a difference. We have the power to change the world for the better or for the worst. There will always be people who don't care about the environment but we do and so we need to do what we think is right. So join the campaign and fight for a better future. For our planet to return to its natural way with incredible biodiversity and amazing ecosystems. We have to make a difference now because all around the world animals are suffocating, drowning, and dying because of humans. You may think it isn't your problem but ultimately you are human and humans make plastic. Honestly, I can't believe that it has gotten to this point. We just have to change something because there is obviously something we ...

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

Pollination

Hello everyone, Today we're talking about pollination and its importance in the world's ecosystems. First a bit of basic plant biology. To reproduce most plants do have a differentiation into male and female, but not in the same way that we see in mammals. Both male and female reproductive organs can be found on the same plant, although not in the same place. Male gametes are produced in the stamens and are then found in pollen. On the other hand, female reproductive organs are called pistils and egg cells are found in the ovule (normally in the flower heads). Pollination describes the process of transporting the pollen to the egg cells, making it an essential part of the reproduction of plants. Nearly all seed plants worldwide require pollination to reproduce. Cone bearing trees also need pollination. Pollination is almost always assisted by other organisms such as insects, birds and mammals to transport the pollen. In some species wind ...

Animals 11-15 in our '50 incredible animals' series

Hello, We have another five amazing animals for you today. Enjoy! 11. Dhole This is a dog species which looks rather like a red fox . They are difficult to put into any of the dog subfamilies. They aren't foxes, nor wolves, nor domestic dogs. Dholes are fast runners and live in packs of 5-12 individuals. Although sometimes, different packs will join forces to become a pack of 30 or more individuals! However, these super packs are broken up after a successful hunt. The different packs rarely attack each other as neighbouring packs are often closely related. Dhole packs live in burrows with multiple entrances. They can be found in eastern and southern Asia. They eat wild berries, insects and lizards and as a pack hunt deer, rodents and other wild mammals. Interestingly, unlike other dogs, they rarely kill by biting at the throat. They are also good swimmers! 12. Irrawaddy dolphin The Irrawaddy dolphin can be found in coastal areas of south a...

10 animals on the edge of extinction you didn't know about no. 9 - South Island takahē

Hello Today we’re talking about the South Island takahē, porphyrio hochstetteri . They are flightless birds, endemic to New Zealand. Takahē are brightly coloured and weigh 2.3-3.8 kg. They have red legs and a large red beak. Their feathers are coloured blue and green. They have wings, but these are only used during courtship or rivalry displays. They are territorial, with one family’s territory reaching anywhere from 4 ha to 100 ha (0,04-1km^2). Pairs will live in the same territory each year. They breed once a year and will raise 1-3 chicks (normally 2) each year. Both parents raise the chicks together. In the wild, takahē live in native grasslands and have a lifespan of 16-18 years. If snow covers the ground then they will move into nearby forests. They eat tussock grasses, sedges and sometimes rushes. But they are opportunists, so they will occasionally go for insects or even ducklings and...

10 Animals on the Edge of Extinction No. 10- The Javan Rhino

The Javan rhino is listed as the 1st animal on WWF’s list of the 10 world’s most endangered animals, and I for my part, had never heard of it! If you hadn’t either, we’re changing that now. A bit about the rhino’s lifestyle The Javan rhinos are now exclusively found on the island of Java in Indonesia, but were once found in vast regions of northeast india and Southeast Asia. They have a dark grey colour which looks almost black when wet, and their (often pink) skin folds look a bit like plated armor. Both males and females have lower incisors which resemble tusks that they use to fight. Males have one relatively short horn of about 25 cm (10 inches). Javan Rhinos live in tropical forests, marshy areas and in the thick bush. They are mainly browsers and eat over 100 plants species they find in the forest, weigh between 900 and 2300 kg (1984-5071 pounds) and are between 3 and 3.2 meters (10- 10.5 feet) long. How endangered are we talking? Javan rhinos are the most ...

March 2021 Factfile - some news from the past month, animals that YOU voted for and more!

Hi Everyone! We hope you are all okay and will enjoy this month's wrap up post. We have managed to post a little more this month but we are off school soon so we may be able to post more! News! Recent European droughts and heatwaves are said to be worst in 2000 years The British newspaper, 'The Guardian' reports that the series of droughts and heatwaves since 2014 have been the worst in 2000 years. These heatwaves have disastrous consequences such as early deaths, crop failure and forest fires. For more information, click here . This is definitely the final bit of proof that climate change exists and that it needs to be stopped! Rise in deforestation in 2020 A horrifying 42 000 squared km of forest was chopped down in 2020, making it the third worst year since 2002. The most affected areas were humid tropical forests such as the Amazon, the Congo and other forests in South America and South-East Asia. These forests a...

September 2021 factfile

Hello, Another month is over and October is here! News Good news Biggest CO2 capturer in the world opens In Iceland , a massive machine has been turned on. It will suck 4 000 tonnes of CO2 out of the air and put it deep into the ground where it will be mineralised. However, critics say that such a machine is not worth it. They say that the machine in itself is not needed because trees and other plants also suck CO2 out of the air in a process known as photosynthesis . Also, the project costs money and planting trees doesn't. I personally understand and agree with both sides at the same time. Protesters make their voices heard all over the world On the 24th, millions took to the streets to make their voices heard about the climate crisis. In Berlin, just two days before the elections, Greta Thunberg started the protest with a speech. An estimated 35 000 people were in Berlin alone. But not only in Berlin. All over the globe, protests halted...
