Review of Dinoflagellate Bloom in term athropological effect and biogeographic range. Abstract Dinoflagellates are common and abundant to the marine and estuarine system‚ it were characterized by the 2 flagella that are located on the girdle and sulcus. The girdle grooves divides the body into 2 parts‚ in which its orientation‚ size and shape can be used to indentify them in morphological taxonomy. Toxic dinoflagellates are known to cause diarhetic shellfish poisoning (DSP)‚ paralytic shellfish poisoning

Thomas Huynh Period 2 Golden Rice Vitamin A deficiency is one the most common nutritional deficiencies in developing regions. Deficiency in vitamin A can negatively affect growth‚ cause blindness‚ and suppress the immune system. To solve this problem green leafy vegetables and yellow fruits and certain animal produces B carotene are used to synthesize vitamin A. This can be done by direct manipulation of an organism’s genome using biotechnology; first isolating and copying the genetic material

Some coastal areas are affected more by socio-economic issues than environmental needs‚ or vice versa. However‚ opportunity costs need to be considered when managing coastal areas‚ where both socio-economic and environmental needs should be met. One place where the need to manage the environment is more necessary is in Dubai. However‚ socio-economic issues were highlighted as being more important in Pevensey Bay and the Isle of Wight. Meeting the environmental needs are pivotal for two places with

Wetland Destruction Wetlands are very important to the ecosystem and human communities. They filter pollution‚ provide habitat for countless species‚ endangered plants and provide natural flood protection. In the 1600s more than 220 million acres of wetlands existed. Due to farming and development‚ by 1980 more than half of those had been destroyed. Wetland destruction is becoming a huge problem. Not only are wetlands disappearing but those still existing are suffering degradation from chemical

Summary: Water pollution remains one of the most visible and persistent signs of our impact on the natural world. Cleanup of some older pollutants has been offset by new contaminants that threaten freshwater ecosystems and foul our drinking water. The sight and smell of grossly polluted waterways provided some of the original impetus to the environmental movement in the 1970s. Nearly a century before that‚ the dangers of polluted water to human health drove what became known as the "sanitary

about what will happen when there is a decline in potable water. Global water pollution caused by sewage and animal waste has resulted in overdose of nutrients and sediments in rivers‚ lakes and sea.(Tasha Eichenseher‚ March 2010) This causes eutrophication which is a situation where algae growth increases; resulted in lack of oxygen in the river. That eventually decreases the values of the rivers‚ lakes and esturaries for recreation‚ fishing‚ hunting and aesthetic enjoyment. In addition to that

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

Carbon‚ Phosphorus and Nitrogen Cycles Humans have a great impact on each of the Carbon‚ Phosphorus‚ and Nitrogen cycles in the Ecosystem. The carbon cycle starts with the reservoir of the carbon dioxide in the air‚ the carbon atoms move from carbon dioxide through photosynthesis into atoms of organic molecules that form the plants body. These carbon atoms are then further metabolized and are eaten and turned into tissue that all organisms in the ecosystem use. Half of the atoms are respired
