How Does Sea Ice Affect Penguins

There are many ways in which increased levels of greenhouse gasses can affect marine life adapted to colder and warmer water, and many ways marine life can adapt to the effects of climate change whether that be beneficial in the case of phytoplankton or detrimental in the case of Adelie penguins loosing numbers in the south pole.

Study conducted by British Antarctic Survey in 2004 emphasized that Antarctic krill numbers are declining. Krill are very significant to the Antarctic food web and this decline could threaten whales, seals and penguins all of which rely on krill. The decline of krill has been associated to a intense decline in sea ice, their habita. Sea ice is a vigorous feeding ground for the enormous number of krill in the Southern Ocean. The research shows that krill decreased by about 80% since the 1970s. Krill feed on the algae which are found under the surface of the sea ice. The Antarctic Peninsula, an important breeding ground for the krill, has experienced an unusual shrinkage of sea ice.

Studies have shown that stocks of krill in Antarctica have declined dramatically in recent years. The reason for this is likely to be a fall in the amount of sea ice in the winter months in the Antarctic Peninsula region.

commercial fishers are one of the competitors of the African penguin which means the African penguin has to fight for all the food that they are getting against the commercial fishers.

Background: Euphausia krill are at the very bottom of the food chain and can only found in the pristine oceans around Antarctcia, where there is very limited accumulation of contaminants. Antarctic krill are one of the most abundant animal species. There are about 500 million tons of krill in the Southern Ocean. Harvested krill is mainly used for the production of krill meal and krill oil, which in turn is used for animal feed and for direct human consumption through health products.

The ocean bottom around Antarctica is turning out to be naturally wealthier as an aftereffect of ocean ice decreases, and in the process cleaning up a carbon's portion dioxide that is creating the loss of that same ocean ice. How critical this will be to putting a beware of a dangerous atmospheric devation stays dubious, however it's an uncommon bit of uplifting news in a for the most part grim picture.

Even if it seems like something small, the population drop of krill created a much bigger effect. The dropping of the krill population led to a food shortage for the penguins, leading to a population drop of their own. Another problem, the ice melting due to climate change. Climate change, a leading effect, caused by the “greenhouse effect” which refers to warming that happens when heat gets trapped by the atmosphere that radiates from Earth towards space. Some gases block heat and it’s ability to escape causing the planet to overall “heat up”. According to ucar.edu “too little ice and the colony gets more exposed and vulnerable to predation,” (Leifert). This leads to the penguins having less space to stay concealed from predators such as animals like skuas, kelp gulls, and giant petrels. These predators come after the chicks especially as they cannot defend themselves. This lack of ice leading to less protection making the innocent penguins more vulnerable to predators. Another cause, the excessive fishing and the careless efforts to enforce safety while doing so. Fishing efforts over the past couple of years significantly increased. The penguin’s prey such as anchovy and sardine stocks get caught decreasing the penguin’s food supply. According to Science Daily, “As fishing efforts around the globe have multiplied several fold over the last few decades, penguins are now competing with people for enough food,” (Science Daily). With the warm temperatures already

Not many people wonder why penguins cannot fly, but they once did. It all started many years ago when Zeus ruled the Earth. One day, all the greek gods and goddesses were sitting on Mount Olympus eating their grapes. It was a hot sunny day and all the birds were chirping songs for the gods. When all of a sudden all the penguins that existed penguins attacked the gods and stole all of their grapes. Zeus and the other gods were furious. Zeus tried striking lighting bolts at the penguins, but they all flew away too quickly. Zeus was determined to find these penguins and punish them.

“Antarctica has this mythic weight. It resides in the collective unconscious of so many people, and it makes this huge impact, just like outer space. It’s like going to the moon.” ( John Krakauer) The antarctic is home to lots of different animals. Some of these are Adelie, Gentoo and Emperor penguins. Other animals are Elephant and leopard seals as well as Snow petrel, polar skuas and albatrosses. Penguins are often the favorite.

For many people, different kinds of stuff fasten alluringness, for Gentoo Penguins, it is a secret, sacred gift. Kudos to the male Gentoo penguins, for they really know how to crush it. The trick is built around a gift that found root in love and protection, what girl's needs. The Gentoo penguin nests are built from roughly circular stones that are guarded jealously and their ownership is a reason for noisy dispute between the males. The female loved the stones, and the smart males go all the way to find it and offer a nice stone to the female of its choice. It always works. The stone-giving male always receives

Penguins to me are one of the most controversial land birds alive. They have the most swag out of any bird that I have ever seen. The creatures I just love because they really do make me happy any time that I see these animals because they have the ability to really get out there and make sure their family is taken care of. When times get hard for these birds they rely on their whole group and they all ways stick together to keep their whole flock protected. The reason why I love penguins so much is because penguins have a way of being the best animals alive and really being able to protect their friends.

Do you ever wonder how animals survive in the warm and cold? Have you ever thought about how animals build their homes and shelter out in their environment? They must do a lot to survive out in the world.

This article explores the possibility of threat to the ecosystem and the food chain of the Ross Sea. The famous Antarctic toothfish plays a vital role in the food chain of the Ross Sea because it serves as a main meal for higher order organisms. Researchers as well as locals have noticed the decrease in the Antarctic toothfish because fishermen were not catching nearly as many toothfish as they were before 2002. This observation was puzzling because the use of a new tool for monitoring the amount of Antarctic toothfish in 2014 showed that the prevalence of the Antarctic toothfish was similar to that before 2002. These findings pushed researchers to hypothesize that either the Antarctic toothfish had recently returned to the McMurdo Sound or

Antarctica has no trees or bushes at all. Plants on Antarctica is made up of mosses, lichen, and algae. Penguins, whales, and seals live around Antarctica, and fish and krill. The male Emperor penguin is the only warm-blooded animal to stay on the continent through the cold winters while nesting on one egg laid by the female (the female spends nine weeks in the ocean and comes back in time for the egg to hatch). There are no native people of people on antarctica. The cold weather is a great location to study how the body and mind adapts to the cold. Scientists also drill for ice cores, which can provide a climate history of the region over thousands of years ago. barely any vegetation makes a good place to look for meteorites. The dark rocks

Researchers fear that global warming, and consequently climate change, will impact primarily on the Antarctic species and that the decline of their populations will continue to be unsustainable. Fortunately, some people are implementing conservation efforts to avoid it, but it seems that they are not enough.
