Whales, a wonderful and magnificent innovation of mother nature. Not only they are beautifying the environment, but also they help to stabilize the ecosystem by maintaining the over flow of the food chain in the sea. Furthermore they are carrying a big value towards the specific country’s tourism industry. From whale watching and whale swimming the certain country can attracts many foreign tourists towards their country. But these creatures are endangered. Whaling is the main threat to their…

Literature Review Temperature The greatest source of heat in water is solar irradiance by direct absorption (Wetzel and Likens, 2000). We might assumed that heat will remain at where it was absorbed and temperature will decrease exponentially with depth, just with the light and may remain constant at the hypolimnion (Lampert and Sommer, 2007). Water has the properties of high heat capacity, thus the larger lake might tends to moderate the local climate and provide the longer growing season for…

found also mircoplastics in living organisms, specifically mussels and oyster. In the north Pacific Ocean, there exists the North Pacific Subtropical Gyre, also known as an oceanic desert. Because of the slow moving currents, there many tiny-like phytoplankton but few big fish or mammals. This area also holds home, to the largest landfill in the world. The gyre has unexpectedly given birth to two large masses of ever-growing trash heaps - Western and Eastern Pacific Garbage Patches –…

Trevor Allen Professor Kuznetsoff English 145 9 December 2015 Shark attacks and Global Warming “Shark attacks occupy people’s minds like no other animal related phenomenon” (site). Recently, shark attacks on humans have seemingly exploded onto the scene, with headline after headline capturing the world’s attention with the unsettling news. The recent increase in shark attacks has quickly become a worldwide topic of concern, with scientists consistently asking the looming question of: why has…

River had the highest TSS levels (100.1 mg/L), because of the high concentrations of agricultural and urban activities in this section of the watershed (Cunha, Bottino, and Calijuri 2010). In the Jacupiranguinha River, high TSS levels have reduced phytoplankton productivity and may decrease benthic macroinvertebrates and fish diversity (Bilotta and Brazier 2008). Although, low TSS levels were recorded in the Pariquera-Acu and Canha Rivers, it may still affect aquatic life. Even though…

Ocean acidification is described by many scientists as a consequence of rapid increase of carbon dioxide absorbed into the ocean. As ocean acidity increases, its capacity to absorb CO2 from the atmosphere decreases. This decreases the ocean 's role in moderating climate change, "they write (Cullinane.1). As serious as this may seem several damaging effects are happening to the oceans as we speak. The most important creatures in the ocean’s ecosystem like coral are being depleted and…

NASA receives 3.5 times greater funding than the National Oceanic and Atmospheric Administration (NOAA), yet NOAA could help preserve the world. Amitai Etzioni discussed how the government should be more concerned about the ocean because it impacts the climate. Government funding should be put towards oceanic studies because people receive a lot of their food supply from the ocean. Finally, Etzioni discussed the amount of energy that could come from harnessing ocean currents. Etzioni has a great…

The purpose of this lab was to study a local lake using it as an example of an lentic community. A lentic community is an aquatic community that is comprised of standing water, lake or pond, as opposed to flowing water, river. Samples of both biotic and abiotic factors at the field site were taken. The biotic factors are the living organisms while the abiotic factors are the physical and chemical samples. A plethora of photosynthetic autotrophs and heterotrophs constructed the population of an…

the entire ecosystem. Speaking of blue whales alone, one whale will consume forty million krill in one day. Dead whales also sink to the bottom of the ocean and create food for other sea life. Lastly, whale feces helps with the creation of phytoplankton, which help to eliminate carbon dioxide from the atmosphere. Phytoplpankton is also a main food source for many species (http://whalingecosystems.weebly.com/ecosystem.html). How should these claims be balanced against world opinion - which is…

Title: Ecological Interactions of Living Organisms in Beaver Creek Statement of the Problem: How do the organisms in Beaver Creek interact with the biotic and abiotic portions of the ecosystem? The sample was taken from Beaver Creek (a tributary of Tookany Creek) in Glenside, Montgomery County, PA. The pH of the creek was 5.5, and the stream velocity was detectable (greater or equal to walking speed). In the area of collection, the stream width was one meter and the depth was 14 cm. There…
