The North Pacific Gyre: Recycling is Dire There’s a new continent in the Pacific Ocean! This continent has been called many things from the great pacific garbage patch to Trash Island. This swirling mass of plastic bags plastic bottles and other non perishable items has been accumulating in the Gyre for years. Caught in the northern Pacific currents that form the N. Pacific Gyre. This Largely covered area of plastic remnants that have been broken down to small pieces have a damning effect on the wildlife that depends on the Gyres currents for food.
According to Frazer (2008), a majority of salmon aquaculture in the Pacific Northwest consists of non-native Atlantic salmon. This is an issue according to Simberloff (2009), because after changes to habitat, research indicates that, “… the second greatest cause of species endangerment and extinction [is introduced species] …” (p. 2). There are several factors associated with invasive species, not the least of which is the spread of disease. Bakke & Harris (1998, as cited in Frazer, 2008) mentioned that hundreds of infections that are rare in wild Atlantic salmon populations are prevalent in farm raised Atlantic salmon. Escaped farmed salmon are then capable of spreading these infections to wild Pacific salmon populations.
Evaluate the relative importance of global and local threats to one named global ecosystem (15 mark) One named global ecosystem is the coral reef. In order for an ecosystem to be a coral reef they would need to be in certain conditions; it usually is where the temperature is around 24 degrees and be in water less than 25m depth. The Coral reef has many global and local threats. The coral reefs are homes to over 25% of known sea creatures and are an invaluable service for the local population as a source of food and income. One major threat is that coral reefs are under huge stress due to the impact that human activities are having and in fact already 1/5 of the world’s coral reefs are so damaged that they are beyond repair.

Sargassum provides resources and habitats for many pelagic fishes. We compared the natural mortality of the blue runner and planehead filefish using a catch curve analysis. The fishes were caught in the Northern Gulf of Mexico and their length measurements were converted to ages to determine their hatch date, daily instantaneous mortality rate
My independent variable is the green crab, which I added to the tide pool off the Washington State coast. My dependent variable was the coral weed because it is affected by the green crab. I started my experiment at 0 crabs/sq. ft. I replicated this step 5 times (resetting the simulation between each replication) and measured the population of the green grab and the coral weed at the end of each repetition.
ACADIAN WHITEFISH This endangered species is a fish mainly located in the Atlantic Ocean. Average length of the anadromous form is about 38 centimeters (15 inches) with an elongated body. The landlocked populations are generally 20 - 25 centimeters (8-10 inches). It was assessed that they were an endangered species in the year nineteen ninety six. This is why it is also called the Atlantic Whitefish (Coregonus huntsmani.)
“The reefs within the Hol Chan area near San Pedro Town are showing signs of stress caused by over collecting and damage from boat's anchors” (Encyclopedia of Earth, 2011). Besides the obvious damage caused by boats, the reefs are also over fished and not just by the locals. The Encyclopedia of Earth (2011) states that “for decades, the Sapodilla Cayes and Glover's Reef areas have been illegally fished by Guatemalan and Honduran fishermen. Since there are no closed seasons or size limits for conch and lobster in those countries, much of the area has been depleted of its conch and lobster populations” (Management
Proposal Presentation By Michael R. Baran BUS 505: Business Strategies & Proposals Instructor: Prof. Nikhil Nayak 16th of December 2012 Proposal Presentation SAIC has been able to conduct research across the globe to understand how the customer in the different continents and in different countries wants their products to work, and what functions are important to them. The Hawaiian monk seal has been delegated as an endangered species of the earless seals from the Phocidae family that live on the Hawaiian Islands. According to (Konica Minolta – Hawaiian Monk Seal-Endangered, (N.D.) “The Hawaiian Monk Seal live on the sandy beach and coastal waters around the Hawaiian Islands. With few enemies, the islands were perfect for the Hawaiian Monk Seals to raise their kids.” (Konica Minolta) If we do not understanding why the Hawaiian monk is on the verge of extinction. We are trying to understand the different threats that are out there that are hurting this species.
