The world we live in today is in no doubt constantly changing all thanks to the technological and scientific advancements. These advancements are what have led to the birth of molecular genetics which is the genesis of improvements in the field of agriculture. Food is a very crucial part of human survival, and while it may be abundant in many developed countries, the same cannot be said about the developing countries. A 2015 report by FAO on the state of food insecurity sates that there are…

This paper explores the reasons behind the functional extinction of the Eastern Oyster in the New York Harbor, the ecological services that the oyster provided to the Harbor’s ecosystem and the steps to bring back this keystone species. When Europeans first came to the New World, oysters were so abundant around New York City that it was considered the Oyster Capital of the World (Driscoll, 2011) but within 300 years this title would be no more as the oyster became functionally extinct due to…

Phosphorus is generally done to control eutrophication. Treatment plant effluent discharge limit have ranged from 0.10-2.5 mg/L. In the biological removal of phosphorus in the influent wastewater is incorporated into cell biomass, which subsequently is removed from the process as a result of sludge…

Hawai’i is known as the endangered species capital of the world with the largest number of endangered species per square mile than any other place on Earth (Meditz et al., 2013). Hawai’i is called this because of an invasive algae called Gracilaria salicornia, or gorilla ogo. Studies on Gracilaria salicornia provide background information of on the specific algae. Current research also analyzes the ecology of the algae, along with how the algae affects Hawaii's economy. Additional research…

Title: See how nitrogen effects water habitats. eutrophication Aims: To see what the effect of nitrogen has on aqcuatic plant growth Hypothesis: I think that the duckweed with some nitrogen will grow the best. Not full stock or half stock but around quarter or eith stock. This is because I think that to much nitrogen will be deadly for the plant but with some nitrogen it will grow better than duckweed without any nitrogen. Method: We took the top off of the coke bottles We cleaned…
