Question

PLEASE BE AS DETAILED AS POSSIBLE. THE PRECISE DETAILS ARE REALLY IMPORTANT IN THIS QUESTION. IT IS A 10 POINT QUESTION THAT I AM REALLY STUCK ON.

PLEASE PROVIDE EXAMPLES

Compare and contrast the effects of fishing on the community structure in kelp forests, seagrass beds, coral reefs and salt marshes.

Answer 1

Before modern ecological inspection started, humans convert Western Atlantic coastal marine ecosystems. Paleoecological, historical and archeologic reorganisation display incredible harm of large vertebrates as well as oysters from the intergrated Atlantic coast. Immense millions of large fishes, sea turtles, sharks, also manatees were evacuated from the Caribbean in the 17th to 19th centuries. Current disruption of reef corals as well as seagrasses are because of eventually to unbind of these large consumers as much as to more current alteration in climate,outbreaks and eutrophication of disease. In the 19th century overfishing decreased oyster's vast beds in Chesapeake Bay as well as another estuaries to a less percent of pristine affluences and benefited eutrophication. Automated bottom fishes harvesting such as cod set off a series of trophic cascades which remove kelp forests and again took them back like fishers fished their way down food webs to small invertebrates. Finally, but most extensively, automated harvesting of the whole continental shelf decimated large, fishes and devastated three-dimensional habitats built up by bryozoans, sessile corals, as well as sponges.
