Tooth bleaching

its worst coral bleaching to date. This Friday, the Department of Natural Resources announced that, as was forecast, coral reefs across Hawaii from the northernmost spot in the Hawaiian Archipielago, Kure Atoll, all the way to the island of Hawaii are already feeling the effects of coral bleaching. Coral bleaching occurs when ocean temperatures rise above their accustomed range, causing coral to expel the algae that they and creatures living in them feed from. It’s called bleaching because as the

Importance of the Parrotfish family Coral reefs support an abundant and diverse population of herbivores, on reefs subject to minimal human disturbance, herbivorous fish such as the scaridae family are predominant herbivores, both in terms of population density and algal biomass consumption. By the consumption of algae, parrotfishes open space for young coral settlement and growth, therefore playing a vital role in the maintenance of coral reefs. This feeding behavior has been observed and past studies

Coral bleaching is a broad yet complex topic that involves the mutualistic and obligate symbiosis between corals and dinoflagellate algae of the genus Symbiodinium, commonly referred to as zooxanthellae. Bleaching occurs when a significant concentration of the zooxanthellae are no longer fixed on the coral, which occurs due to an inability to perform their role (Wooldridge and Done 2009). With the often colorful dinoflagellate algae gone, the coral is left as a white carbonate skeleton (Douglas 2003)

1. Policy Description Introduction Worldwide we are facing an epidemic of large-scale Coral Reefs bleaching themselves white. Although white coral is not dead it is likely to die shortly after bleaching. The main problem is global warming, this causes overfishing, pollution and rising ocean temperatures with more acidity. Global warming is an issue that affects our planet, especially in the ocean. This problem has also an economic and political impact because "If the reefs vanished, experts

Cho, “The reefs hold an annual global economic value of $375 billion, providing food and resources for over 500 million people in 94 countries and territories” (Cho). However, the reefs are in a detrimental crisis that could end in chaos. Coral bleaching is occurring around the world. Heat stress from global warming triggers the symbiotic relationship between polyps and zooxanthellae to collapse. This results in the expel of photosynthetic algae, leaving them bleached white. The coral reefs are in

Coral reefs are found in shallow tropical waters along the shores of islands and continents. Coral bleaching is a topic that gets left in the dust. Not many people really pay attention or show much interest in it. Widespread bleaching, involving major coral reef regions and resulting in mass coral mortality has raised concerns about linkage of the events to global phenomenons including global warming or climate change and increased UV radiation from ozone depletion. Corals provide a lot not just

The US Virgin Islands, which constitute of St. Croix, St. Thomas and St. John, are US territories located amongst other Caribbean Islands. With little natural resources to support them, these islands rely heavily on specialized ecosystems, such as the coral reefs and mangrove forests, for sources of food and income through tourism. With a special adaptation to salt water and a unique ability to thrive in oxygen depleted environmentals, mangrove forests are among one of the most common wetland systems

and if the water keeps changing, bleaching will become more common and the health of the coral reef will begin to decline. In 1998, an enormous underwater heat wave hit and killed 16% of the coral on reefs around the world. This was caused by the El Nino and became known as the first major coral bleaching event to occur. The next major coral bleaching event took place in 2010 and it was triggered by the El Nino again. Currently coral is going through another bleaching event that began in 2015 and is

Moon Jellyfish are in the “Animalia Kingdom, Phylum Cnidarian, Class Scyphozoan, Order Semaeostomeae, Family Ulmaridae, and Genus Aurelia” ( Myers, 2016 ; Espinosa, ; 2016 ; Parr, 2016 ; Jones, 2026 ; Hammond, 2016 ; Dewey, 2016). The morphological description of Cnidarians are corals, sea anemones, jellyfish and hydroids. These cnidarians form a diverse phylum that contains ~9000 species, which live in aquatic (predominantly marine) environments. The phylum-defining trait of Cnidaria is the stinging
