Biodiversity We know very little about the earth’s aquatic biodiversity because there has been so little exploration of the water on this ‘water planet.’ A. Three patterns of marine biodiversity are: 1. The greatest marine biodiversity occurs in coral reefs‚ estuaries‚ and on the deep-sea ocean floor. 2. Biodiversity is higher near the coasts because of great variety of producers‚ habitats and nursery areas. 3. Biodiversity is higher in the bottom region than in the surface region of the ocean because

Stand on a street corner and ask people if they know what insulin is‚ and many will reply‚ "Doesn’t it have something to do with blood sugar?" Indeed‚ that is correct‚ but such a response is a bit like saying "Mozart? Wasn’t he some kind of a musician?" Insulin is a key player in the control of intermediary metabolism. It has profound effects on both carbohydrate and lipid metabolism‚ and significant influences on protein and mineral metabolism. Consequently‚ derangements in insulin signaling have

the surrounding reefs and the abundant fish that populate them is breath-taking‚ a fact that is appreciated by the multitude of tourists who flock to the island each year to engage in snorkeling and scuba diving. Baring this in mind it is hard to believe that only thirty years ago overfishing‚ to accommodate an ever increasing population‚ and destructive fishing methods conducted by the native population nearly destroyed the fragile ecosystem that surrounds Apo Island. These reefs‚ and the marine

BRANDING AN ISLAND: THE PALAUI STORY by Chen Reyes-Mencias 09272795807 http://www.bluewaterconsultancy.info http://www.palaui.info Twenty years ago I set foot on an island that was nothing but fantastic. It is at the tip of Luzon 642 kms. north of Manila. At that time it was a logistical nightmare to go there and so my last thought before I headed back home was that it may be the first and last time for me to see it. The island is called Palaui and is located in Sta.Ana‚ Cagayan. In 2005

Definition: Coral reefs are underwater structures made from calcium carbonate secreted by corals. Corals are colonies of tiny living animals found in marine waters containing few nutrients. Most coral reefs are built from stony corals‚ and are formed by polyps that live together in groups. The polyps secrete a hard carbonate exoskeleton which provides support and protection for the body of each polyp. Reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. Often called “rainforests

Coral reef are the most biologically diverse ecosystem on earth which are it is the most productive area as compare to the rainforest and the mangrove area. Coral reef fish are fish which live near to the or close relation to coral reefs. Coral reef forms a complex ecosystem with various biodiversity. Many species of coral reef fish can be found in an area of healthy coral reef area either they are hidden between the reef areas or they are well camouflaged with their environment. Coral reef fishes

necessary symbiotic relationship with coral‚ zooxanthellae also serve as the component responsible for the lush and vibrant colors of the coral reefs. A good indication of whether or not a reef is healthy is the amount of color present. Since the algae contains photosynthetic pigments‚ the degree of light it receives can alter the colors‚ hence the colorful reefs. The algae are sensitive to light and temperature‚ and expel zooxanthellae cells when they undergo conditions that place stress on them‚ such

Coral Bleaching Coral reefs deliver ecosystem services to tourism‚ fisheries and shoreline protection and often called “rainforests of the sea”. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Coral reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. However‚ coral reefs are fragile ecosystems‚ partly because they are very sensitive to water temperature. They are under threat from climate change‚ oceanic acidification‚ blast
