in the environment is the increase in temperature and the rise of sea water levels globally. According to National Ocean and Atmospheric Administration, the global sea level and has risen up 2.6 inches and continues rise at a rate of about one-eighth of an inch per year. With this being said, many ecosystem consisting animal, marine and microbial life will be affect. A particular animal that is in question is sea urchins. Sea urchins are marine organisms that have been experiencing a higher mortality

Chilean sea urchin, Loxechinus albus Introduction: The Chilean Sea urchins Loxechinus albus (Molina, 1782) is an edible echinoderm animal of the family Parechinidae. This species is native to the coasts of Chile and Peru and is considered among the key benthic herbivores in Chilean coastal waters. It is harvested commercially by fishermen and is considered an ingredient in Chilean cuisine.

the world about the life they interact with or observe. The reason they do this is that it tells people whether or not they should get close to them or if they are dangerous. Saltwater ecosystems consist of life that is found or produced in the sea; that’s what marine biologist stands for. Some people are highly interested in topics such as this if they are and they stay consistent on liking it then, they might grow up to be a marine biologist. Marine Biologists don’t just study the saltwater

eat? Sea Urchins How does the consumption by the otter effect the growth of the Kelp forest? The major threat to kelp forests is presented by sea urchins, which can eliminate the forest. Sea otters are the main predators of sea urchins and keep the urchin population in check. Is this a direct or indirect effect? Direct effect - sea otters on sea Urchins.

A constant and pertinent literary metaphor used throughout Beowulf, translated by Charles W Kennedy, is that of the sea. The sea in Beowulf is a single object that not only acts as a place for entertaining battles, but also serves as a plot device that reveals the poem’s contrasting views on religion and death. It also gives validity to Beowulf’s position of power, playing a vital role in his character development, as well as the development of the plot. It is vital for Beowulf, as the poem’s main

Russ Kramer’s painting Far From Home of a small sailboat all alone on the open water can be seen in many different ways, some better than others. In Dorothy Allison’s essay she talks about people hiding their “secret selves” when they look at paintings and how each person has a certain “version of reality” that makes their “secret selves” (595). I agree with Dorothy Allison that everyone sees things differently based on their own personal “version of reality” that is determined by their past experiences

setting in Tasmania. The novel helps to explore the idea of how different setting effect the people, with the sea being a place of beauty and danger. Though out this essay I will expand on the ways both the setting in the novel and film have percenlaty of their own and how they effect the choices and action of the people that advancer into them. Though out the novel ‘Past The Shallows’ the sea is a place that keeps on drawing them back to it. Manly it is meant be ascocted with bad things and death in

is a small painting with sizes 55.3 x 46 cm, but it contains explosive and bright colors. Matisse has portrayed the scene in an inviting and light-filled way and with a large variety of tones and colors used to paint the boats floating on the calm sea and the sky during the sunset. The use of such unnatural colors and the presence of revolutionary minimalist strokes represent the key features of the “art of the beasts” and provoked agitation within the critics. The colours of the painting are the

into a research paper, I am going to make many revisions. Based on your feedback, I will add in more examples. Specifically, more research on the sea turtle example given in my paper. By including additional research about this topic readers will emotionally connect to my topic. I intend to go to the library and find an article about how litter affects sea turtles and statistics on how many injuries and deaths occur because of our litter. Another example that needs to be expanded on is how much litter

natural. As i mentioned in the beginning that both of the paintings were took place near the ocean, it is because i noticed there were dophins, seashells on Raphael's Galatea; while Botticelli's The Birth of Venus had the Goddess of Venus standing at a sea shore on the ocean.

companions on his journey on the sea. In the wanderer it talks about his hardships and what he went through watching the kinsman be slaughtered and ruined. In the wife's lament it talks about deep sadness and how her lord left her and sailed away. These three poems are all in the same union of the meanings and can all be ran together if needed. In the seafarer from the Exeter Poems, when it talks about the loneliness it is talking about how he is all alone at sea and he has nobody to actually spend

The Finest Hours by Michael J. Tougias and Casey Sherman is the true story of the brave men who risked their own lives to save others. The journey across the sea consisted of many situations that they had to face. Not many people would risk their own lives to save someone else’s. The book describes the situations in a great deal, and any reader will enjoy reading the book. I personally think that the theme of the book is hope. This is because throughout the whole story the survivors never gave

Richard Vevers traded a career in advertising for a “wetter” job as an underwater photographer in Australia. As a landlocked teenager growing up in Bromley, England, he was fascinated with the idea for years. He has certainly come a long way since then. Thanks to a partnership between Google Street View, he and his team at Catlin Seaview Survey are responsible for creating “the most viewed underwater imagery of all time.” (http://www.wired.com/2014/10/take-google-seaview-tour-worlds-stunning-coral-reefs/)

ea otters are an essential keystone species in a marine ecosystem. They help to keep down herbivore populations to keep kelp happy and they keep sea urchin populations down. Sea otters are mammals that live in oceans often around california kelp forests. They live in chilly waters but have no blubber (Picky Eaters, p.1). Instead they have a thick coating of fur. This fur is thought to be the thickest fur of any mammal. The kelp forests that they live in range in temperatures of 42- 72 degrees Fahrenheit

AP Environmental Science: Chapter 5 1. Explain how southern sea otters act as a keystone species in kelp beds. The otters help to keep sea urchins and other kelp-eating species from depleting highly productive and rapidly growing kelp forests, which provide habitats for a number of species in offshore coastal waters. Without southern sea otters, sea urchins would probably destroy the kelp forests and much of the rich biodiversity associated with them. Explain why we should care about protecting

1911, Southern sea otters swam on every coast near the Pacific, Including the Sea of Japan. They lived in large kelp forests near shores and would usually stay on the surface of the water only diving when food was necessary. Being the most important part of the food chain, sea otters kept anything that would eat the seaweed like snails, and sea urchin populations in check so the kelp forests wouldn 't die out. Southern sea otter populations near the west were unknown, but the American east coast

1) Explain how and why human interaction has caused the environmental change to the chose environment in both countries? Coral reefs are an environment to a vast range of different species. 25% of all global reefs have been destroyed by humans. 60% percent of coral reefs are under threat by humans. The Great Barrier Reef is one of the largest reefs located in Queensland Australia, it is hugely impacted by humans. Pollution, tourism, and mining have all had a huge negative impact on the reef.

I am pretty sure are whole class is so excited to go on this field trip today. We are going on a cruise to the Caribbean. Are class did an amazing thing to go on this trip. St. Judes Children Hospital asked are school to raise money in order to help their research and save many kids lives. The class that raised the most money got to have the chance to go on a cruise. We raised over $5,000 dollars that was the most the school raised this year. We are leaving on a Charter bus and going to Florida
