Rocky intertidal zonation at Lawrencetown Beach Introduction Nova Scotia has an extensive coastline with varying degrees of exposure. The intertidal zone (littoral zone) is where the ocean meets land and around Nova Scotia’s coast this zone is highly diverse, from salt marshes to mudflats and rocky shores. The intertidal zone is the area that is exposed to air at low tide and submerged by water at high tide and the species that are located here need to tolerate various levels of exposure. The factors that affect the abundance of species present in an area vary with spatial scale.…
Elizabeth Kolbert’s book, The Sixth Extinction, covers the argument that we are currently in another mass extinction because the Earth is following similar trends as it did in the past five mass extinctions. The first chapter of The Sixth Extinction starts out by discussing frogs. Frogs are the one of the oldest species on Earth; however, the extinction rates of frogs is higher than it’s ever been, and it’s only increasing. Kolbert then focused specifically on Panamanian golden frogs. Not too long ago, these frogs were plentiful, but recently the numbers have decreased due to human’s introducing a native species to Panama: Chytrid fungus.…
The acidification of our oceans increases the likelihood of coral reefs to be destroyed or broken down due to erosion. These nearly extinct ecosystems that are either becoming unstable or are being destroyed forces species to find another environment to make their home or to adapt in. The low survival rate of coral reefs under such harsh conditions makes the survival rate of other organisms detrimental as well because it leaves them vulnerable with the reduced amount of living spaces for fish. Leaving fish open to predators, it also has a harmful effects on a fish’s organs. Even though fish do not have shells, they are still affected by the changes that ocean acidification can cause.…
Climate Seasonal Temperatures Modoc Plateau features moderately extreme weather, with warm summers and cold winters. In the summers, average temperatures can reach 30°C (85°F) during the day and 8°C (47°F) during the night. On the other hand, winters have daytime temperatures of 5°C (42°F) and nighttime temperatures of -6°C (20°F). Temperatures in the Modoc Plateau are generally similar from region to region, with the exception of nearby mountains such as Mount Shasta. Precipitation Unlike temperatures, average rainfall in the Modoc County (and Modoc Plateau) is quite dry and varies from region to region.…
One such species that play a enormous role in the Chesapeake ecosystem is sea grass. Much of the public is unaware of what benefits sea grass actually poses on the environment, but their role is to provide food for many aquatic creatures, serve as a home for these creatures, and help clear the water by filtering out nutrients and replacing them with oxygen. An oxygen-rich habitat is key for a thriving ecosystem. What is causing many patches of sea grass to vanish is cloudy water that prevents sunlight from reaching the bottom dwelling plants, thus creating no oxygen, and filtering little nutrients. The second species that has a huge affect on the environment are oysters.…
1.The increase in salinity is the main cause because of the problems of the faraway locations and because of the local cities waste that runoffs causing an accumulation of nutrients leading to salinity and even eutrophication. Which has caused deaths of fish and birds. As well as embryo defects to the fish residents of the Salton Sea. Making the Salton Sea a death trap instead of a safe substitution of the past wetlands. 2.…
It is predicted that global warming will cause major flooding in Delaware along the coastline resulting in the loss of natural habitats, the loss of real estate, and the loss of tax revenue. Loss of Natural Habitats Normally, wet lands keep pace with the gradual sea level rise through constant vegetative growth and a healthy sediment supply from up streams and tributaries. If sediment supply into the estuary system begin to lower, or sea level rise outpaces growth, wet lands can become submerged, and for all intensive purposes, reduced to open water areas. Unfortunately, Delaware is already losing wetland due to the sea level rising. By the end of the century, many of the Delaware bays coastal marshes could disappear.…
Over time, natural selection also takes place, and this results in the “best” meaning the organisms that are the fittest to live for longer, and most likely to reproduce surviving (survival of the fittest). But when non native invasive species are introduced to such an area, they end up destroying the environment and that ecosystem. They eat any fish or plant from that area, hence not keeping biodiversity, and kill species and their habitats. These species dominate the sea, and have very high biotic potential- conditions in which species survive the best and increase in number, for eg: less predators, lots of food, lack of disease or any other risk. This causes the environmental resistance of native species to decrease, and they begin to reduce in number.…
Franklin D. Roosevelt explained, “Prosperous farmers mean more employment, more prosperity for the workers and the business men of every industrial area in the whole country.” Franklin D. Roosevelt was the 32nd president for the United States and is famous for providing unemployed Americans with the New Deal. The Industrial Revolution was the increased production of goods by use of machines or other technological advancements. Industrialization caused a major shift in technologies which eventually paved the way for the modern industrial world.…
There is an ever-growing pressure being placed upon the mangroves in Australia as over 80% of Australia’s population live within 50km of the coast. Land is becoming more in demand and because people aren’t well educated about the benefits of mangroves on the biodiversity of the world, the immediate reaction is to rid the mangroves to make room for construction to cater for the increasing population. The quality and productivity of mangroves are also being affected by the increase on human activity, and when mangroves are lost or disrupted then their ecological and economic functions cease. The most obvious affects from the lack of mangroves would be, the loss of nurseries for fish to grow, increased salinity on the coast and in water supplies, and an increase in coastal damage from natural disasters (Burnett Mary Regional Group for Natural Resource Management Ltd, 2017). Over the course of 200 years approximately 17% of all of Australia’s mangroves have been destroyed and this loss of mangrove habitat has had a direct impact on the functionality as a viable ecosystem.…
All of the rivers and streams are in threat of being polluted, which is a 40,000mile radius (yubanet.com). Lots are animals are now dying because of all of the pollution that is all around them. Sea creatures are starting to float to the top because of all of things they are around and to the things that they are eating. Lots of fish are eating anything they see in sight. Also because they are tempted to eat whatever because they trash looks like what they want to eat.…
Heart Reef The Heart Reef, in the Great Barrier Reef, is a beautiful organisation of coral and rocks naturally formed into the shape of a heart. The reef was created by hundreds of years of dead coral building up in a massive, underwater stone wall, which has then grown algae and new coral, which reproduces, dies and grows year by year. The Heart Reef is a beautiful array of stunning coral formations, naturally shaped into a heart.…
How and Why California coast (Pacific Coast) is Eroding faster than it should and the effect of it. I chose the California Coast or the Pacific Coast as it is one of the most popular coasts in the world. California has always been in the news for various natural disasters like forest fires, earthquakes and now Coastal erosion. California is also the World’s IT capital where all the famous companies like Google, Facebook, Apple etc are located. Many Indians migrate to california for jobs.…
Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…
(Gain attention) President Barack Obama once said “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.” (Reveal Topic) This statement by President Obama on climate change conveys how important the fight against climate change is. (Establish Credibility) I became interested in this topic after getting into a disagreement regarding climate change with my grandfather and how he doesn’t “buy into that liberal bullshit,” so I set out on a mission to prove him wrong by conducting research with the goal of fully understanding the climate change debate.
