with a breathtaking underwater world and picturesque landscapes around. Honolua Maui is adored by snorkelers from all corners of the world for its amazing formations of corals, a plethora of colorful fish including famed Humuhumunukunukuapuaa and Green Hawaiian Sea Turtles. Honolua Bay Map Honolua Bay is quite big. The water may be accessed from the beach, by downhill hike or from a boat. Most people go into the water from a little patch of sand beach at the left-hand side. It’s not the best…

The Marine iguana which is a reptile is only found on the Galápagos Islands. They are herbivores and feed mostly on the algae on the rocks they lay on near the shore. The males, which are larger than the females, may grow to 4 feet or more. Iguanas seem to prefer rocky shores but may also be found in mangrove swamps and beaches. The iguanas can dive over 9 m down into the water. The lava lizard is a reptile which are native to South America. There are around 20 recognized species but only 7 of…

What are some common symptoms of food poisoning? Based on those symptoms, which dinoflagellate do you think is responsible for the outbreak? A bloom of dinoflagellates can change the water color colloquially known as red tide. Red tide can infect shellfish and cause shellfish poisoning if people eat the bad shellfish. Some symptoms of shellfish poisoning are nausea, vomiting, and diarrhea Explain how an HAB outbreak can have a devastating economic impact. There would be a bad impact on…

The Crown of Thorns starfish (Acanthaster Planci) Anjali Barnes 2016 Ms. Lee 9X Acanthaster planci Introduction The Crown of Thorns starfish, or Acanthaster Planci, is one of the largest threats to the Great Barrier Reef. The starfish, also known as COTS, can have up to 21 arms, each with hundreds of toxic spines. They move by expanding and contracting these feet, and feed on hard coral. Abiotic features are non-living or physical factors and can have a large effect on the Great Barrier Reef…

The article “Forecasted Coral Reef Decline in Marine Biodiversity Hotspots under Climate Change” examines the suitability of habitats for coral reef development and growth concerning mainly the factor of thermal tolerance. Coral reefs are home to many species and these habitats are key for maintaining biodiversity, yet under climate change this highly diverse system is very vulnerable, especially to changing sea surface temperatures. A slight increase in sea surface temperature can lead to mass…

Acropora Millepora is just one of the many types of coral species in the world that are affected by coral bleaching. As the previous section looked at the organismal level of these particular species, this section will now take the perspective at the population level. Population ecology is defined in the book of Environmental Science as “ the study of factors that cause populations to increase or decrease” ( Friedland 151). These factors may include what enables species to thrive in a certain…

Global climate change: there is now sufficient evidence that global climate change, the emission an accumulation of greenhouse gases in the atmosphere, has had multiple effects on coral reefs. (Lesser, 2010) Terrestrial, aquatic and marine ecosystems are all affected by climate change. Coral is a vital part of the Great Barrier Reef ecosystem, without it there would be cascading effects. Coral bleaching is primarily caused by ocean temperature increase, but can also be caused by increased…

plants, are water milfoil, hornwort, and water primrose. Floating plants, float on the surface of the pond. They do not need soil, as the extract their nutrients from the water. Floating plants are extremely beneficial as they control algae. Floating plants control algae by restricting light, and filtering out excess nutrients. Some examples of floating plants, are duckweed, and water…

predator to plant. According to the model, H. arenicola can only undergo division if it contains its symbiont. The division a symbiont-bearing H. arenicola cell produces two vastly different cells. One of the daughter cells is green coloured because it retained the entire green alga symbiont while the other daughter cell is colourless and free of symbiont. The symbiont is never shared between the two daughter cells because it always polarizes to one side of a dividing H. arenicola cell.…

nauplii reach approximately 1 mm in length (about 3 to 4 days), water will be drained out using filters and about 100 ml of the concentrated nauplii will be collected and feed with appropriate algae source in 2 tanks. Feeding will be repeated once the Artemia has cleared the tank of motile, suspended algae, typically 2 to 4 days depending on the density and size of the Artemia. During the six-week spiking experiment, HgT and isotopic ratios will be measured in Artemia samples every week…
