Algae

Coral bleaching is caused by multiple stressors. One stressor is when water temperatures that are warmer than normal. The rise in the water temperatures cause the coral to expel algae that thrive in their tissues. When this happens, the coral will turn white. If the bleaching happens for too long it will cause the coral to die. In 1980, global warming caused 80% of the Indian ocean corals to become bleached, about 20% of them died…

food poisoning include nausea, vomiting, diarrhea, dizziness and respiratory distress. • Based on the above symptoms I think brevetoxin , which is produced by Karenia brevis would be responsible for the outbreak. Karenia brevis (K. brevis), a marine algae, causes red tides. 2. A HAB outbreak can have an economic impact: • HAB can affect tourism, public health, jobs, public safety, and coastal communities because it can contaminate water sources used for personal use, recreational use, and…

C: The MAR is a vital piece of the Ccaribbean area because of the benefits it provides to oceanic life and the people living in coastal cities and towns. E: The reef is home to over five hundred aquatic species,, but this is only 10 % of the ocean is currently discovered, leaving 90% waiting to be researched (Barbezat). The reef is home to many endangered species, including, one of them being Whale Sharks. E: Although Whale Sharks also reside in Australia’s Great Barrier Reef, if they were to…

more than 17 million people (NOAA). Baltimore, one of the most important North Atlantic port is located on the Chesapeake Bay. Oysters are one of the biggest resources of the Chesapeake bay. Ecologically, oysters are important because they filter algae, sediment, and pollutants. They maintain a good water quality and salinity. Oysters can tolerate a wide range of salinity, between 10ppt-27ppt. Humans have had huge positive and negative impacts on oyster population. Things that destroy an oyster…

either found alone or often in pairs. Prey/Predator The predators of the queen angelfish are people. People capture queen angelfish and sell them to aquariums. The queen angelfish are omnivores, so they eat plants and meat. They eat mostly sponges and algae, but they also eat sea fans, soft corals, tunicates, and jellyfish, if the chance comes up. “Young queen angelfish feed by setting up cleaning stations in sea grass where larger fish come to have their skin parasites removed.”…

change. Our chlorophyll a content was 18.26 ug/L (table 1 in the appendices). Furthermore, the abundance of phytoplankton sampled from Ada Hayden supports our prediction (Table 3 and Figure 3, in appendices). We found more cyanobacteria and green algae which are more commonly found in mesotrophic lakes (Claustre 1994). The results of our…

The Historical Predation of the West Indian Manatee The West Indian Manatee (Trichechus manatus), also known as the sea cow; was listed as an endangered species by U.S Fish and Wildlife Services in 1972. However, since then it has been downgraded from an endangered species to a threatened species (Heavy Poaching in Prime Habitat: The Conservation Status of the West Indian Manatee). The main reasons behind their decline; are pollution in the water, powerboats, and slow reproduction. As a result,…

Algae contribute to about half of all oxygen production(Chapman, 2013). They are photosynthetic, meaning that they produce their own food from sunlight, water, and nutrients, and are usually found in any water habitat(Smithsonian, 2016). The fact that algae produce oxygen is important because dissolved oxygen is very important to the health about of a water body(Water properties: dissolved oxygen, 2016). Human activity runoff is a major source of water pollution(Runoff, 2016). Runoff can pick up…

Nhuy Nguyen Mrs. Pirchio AICE Marine Science 27 September 2015 Hunter and the Hunted Interrelation Population 1. Introduction: From Mexico, to Alaska, and even within Japan, there’s a high chance of being able to visit areas where sea otters can be sighted. Sea otters, also known scientifically as, Enhydra lutris, inhabit shallow coastal areas and they prefer places with a lot of kelp. They use the kelp surrounding them to wrap themselves in while they’re resting. They are very sociable…

In the Baja California coast of Mexico, shrimp ponds were reported to be affected by algal blooms and the responsible algae were the prasinophyte Nephroselmis sp., Cochlodinium polykrikoides, Prorocentrum rhathymum, P. minimum, and Heterocapsa triquetra (dinoflagellates) and Nitzschia sigma (diatom) (Gárate-Lizárraga et al., 1999; 2004; 2006; Sierra-Beltrán et al., 2005; Gárate- Lizárraga and Muñetón-Gómez, 2008). Severe losses in shrimp farming in Mexico caused by toxic dinoflagellates and…
