diverse marine ecosystem. (Bellwood and Wainwirght2002) Coral reefs are the largest natural structures in the world and occur in over 100 countries. They are the result of a remarkable relationship between coral animals and microscopic algae. The microscopic algae (zooxanthellae) coverts sunlight and carbon dioxide into oxygen (photosynthesis) and carbohydrates for the coral animals (polyps) to use and make into calcium carbonate. The calcium carbonate forms marine organisms known as coral. Coral

Isolation and Purification of Lyngbya majuscula on Nutrient-enriched Agar Plates A Special Problem Isolation and Purification of Lyngbya majuscula on Nutrient-enriched Agar Plates ABSTRACT Lyngbya majuscula samples were obtained from the Phycology Laboratory stock culture of the UPV Institute of Aquaculture. Five (5) mm fragments of these were inoculated into agar plates that used 1% agar concentration enriched with varying concentrations (1.0%‚ 1.5%‚ and 2.0%) of Hughes‚ et

Effects of Ocean Warming Around the World Global warming has become a very hot topic in recent years with the increasing global climate and amount of greenhouse gasses. A little known fact‚ however‚ is that about 84% of the total heating of the Earth over the last 40 years has gone into warming the oceans. This warming of the ocean is having widespread effects from loss of biodiversity to the increasing number of tropical cyclones. Even changes of less than 5°C are having effects seen around the

The Great Barrier Reef‚ located off the coast of Queensland‚ Australia‚ is the “world’s largest coral reef ecosystem”‚ according to the Great Barrier Reef Marine Park Authority (GBRMPA). It is home to about 2‚900 individual coral reefs‚ but unfortunately‚ as of 1990 and continuing until today‚ this number is rapidly declining. This active downturn is primarily due to the catastrophic coral bleaching event being held in their ecosystem. Coral reefs have an optimal water temperature of (20-27 celsius)

ABSTRACT EXAMPLES Writing an Abstract – Examples Each student who completes a science fair project must write an abstract to be displayed with the project. An abstract gives the essence of the project in a brief but complete form — it should not exceed 250 words. Judges and the public should have a fairly accurate idea of the project after reading the abstract. The abstract must focus on the current year’s research and give only minimal reference to previous work. Details and discussions should

operculum. Periwinkles are herbivores that feed on algae such as‚ Green algae and diatoms. Green algae is common in areas where light is abundant‚ such as shallow water or rock pools. They use their radular (tiny teeth) to scrape algae off of rocks. Green algae can range from single-celled organisms to multi-celled organisms‚ such as Sea lettuce (Ulva Lactuca). They live in large colonies ‚ close to water. Periwinkle’s diets consist mainly of green algae. On the day of our data collection‚ we noted that
