Cause and effect of global warming Global warming occurs when the levels of greenhouse gasses rise and less infrared light‚ or heat‚ escapes the earth ’s atmosphere. Thus‚ the temperature experienced on Earth begins to rise. Climate change is a part of the Earth ’s history. There have been dramatic fluctuations in overall average temperature for the past 150‚000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with

Potential Abiotic and Biotic Impacts of Zebra Mussels on the Inland Waters of North America. Intergrative and Comparative Biology 36:287-299. This article talks about how the mussels and how they clear the water by removing clay‚ silt‚ bacteria and plankton. It also says by the clearing the water increase growth of benthic plants.

with marine animals and shorelines than the reefs. At second look even the corals looked fine‚ and scientists took lots of samples to see if the oil had reached the sites. A sediment trap was used to research the corals and the research showed that plankton filled the cups and that oil had made its way to the coral sites but that it had not affected them. What I learned was that‚ oil coming out of a well was 100*C‚ this was entering water that was 4*C at high pressure. This oil formed a fine deep water

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water

Secondly‚ Biotherm register the patent of Pure Thermal Plankton (PTP). PTP is a natural component‚ which has thrice capability to enhance people’s immunity of skin and keep skin youthful. Biotherm biologists found PTP fifty years ago‚ and it registers the patent for all products. Thirdly‚ Biotherm has good reputation

Lab Activity #3: Collection and Identification of Plankton at Lake St.George Discussion Questions 1. Phytoplankton are the organisms that were the most abundant in my sample‚ specifically from the Protista kingdom 2. I think that phytoplankton are more indicative of oligotrophic lakes‚ where-as zooplankton are more indicative of eutrophic lakes. I think this because‚ since phytoplankton are capable of producing their own energy‚ they don’t need the nutrients that eutrophic lakes offer‚ and they would

------------------------------------------------- Annelid The annelids (also called "ringed worms")‚ formally called Annelida (from Latin anellus "little ring"[2])‚ are a large phylum of segmented worms‚ with over 22‚000 modern species including ragworms‚ earthworms and leeches. They are found in marine environments from tidal zones to hydrothermal vents‚ in freshwater‚ and in moist terrestrial environments.They are bilaterally symmetrical‚ triploblastic‚ coelomate organisms.They have parapodia

change in their preferred habitat or changing the impoundments. Environmentally‚ they have a huge impact. These fish compete with many native fish‚ such as freshwater mollusks and paddlefish. Asian carps can eat almost anything. Silver carps feed on plankton‚ which native larval fish and mussels depend on. The carps even feed on the native mussels‚ which are already endangered. If patterns continue‚ the carps could eventually hurt native fish by damaging their habitat or by driving them toward extinction
