When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health.
Introduction The Pacific viperfish or if you want to use its scientific name it would be Chauliodus macouni. It is a predatory fish that lives in the abyssal depths of the deep sea. It is a very ferocious creature of the deep. Humans don't have to worry about them because they can't get to us because they need to stay in the deep abyss to stay alive where the pressure is just right for them. There are 9 known species of viperfish known and the most common one is the sloanes viperfish but the one i'm gonna be talking about is the pacific viperfish
The dispersant is fatal to a wide array of marine species and if they are not fatal to the effect of the dispersant than at the less they are vulnerable to the effects. The effects or not, only limited to sea but also the sky. The dispersant affect the birds that make their resting place in the sea it destroys their protective waterproofing and insulating features common to the birds who take residence in the sea. Corexit contains a solvent that can cause cancer in some animals which is very deadly.
There are many different plants like algae, seagrass, phytoplankton, coral reefs, seaweed, marsh grasses, and many more. There is a huge problem with overfishing at the moment and if it goes on there will not be enough fish more the food chain to function and then more species will get extinct. Desert biomes are very interesting as during the day the heat is almost unbearable for humans but animals have adapted and they can stand the heat. At night is a completely different story, instead of the weather being extremely hot at night it becomes super cold. The animals in the desert biome need to adapt to the different temperatures.
On the other hand, the importance of Daphnia in the food chain is significant as Daphnia is preyed upon by several aquatic organisms such as tadpoles, salamanders, aquatic insects, and many of small fish species. Ultimately, and by the end of the chain, food fish for human consumption could be affected as a result of the negative changes in Daphnia
On the other hand, the meiofauna found on beaches with large grain sizes can reach deep into the sediment (Rodriguez et al., 2003), in order to avoid the effects of wave action at the surface. Macrofauna can be negatively affected by wave action on beaches with high wave action and, therefore, tend to reside in more favourable beaches that have less wave action (McLachlan et al., 1996; Rodriguez et al.,
An organism that thrives at high pressures is called a piezophile or barophile. These organisms have a waxy cell layer that helps them survive the crushing pressures found below the sea. It has been difficult for studies to be done on such organisms because of the pressure and temperature barrier. A study done on bacteria from the Mariana trench concluded that “much of deep-sea microbiology may have been done with spurious deep-sea organisms due to warming of samples” (Yayanos, Dietz and Boxtel, 1981). The pressure of the deep ocean is incredibly hard to recreate in a
Threats: Increased exploitation of sea cucumber populations represents major threats to sea cucumber; several cases can confirm that such as the significant decline of sea cucumber in the Red Sea which took place over a limited period of time. Predators are also threating sea cucumber. Self-defense: Animals have different self defense mechanisms against predation. Sea cucumber may propel their own toxic internal organs from their anus in the direction of predator’s attack. Some of sea cucumber species are able to emit sticky threads when threatened to ensnare their enemies.
There very rough water. Both the acorns have hard shells and are cemented to the rock. Because the brown barnacle is at high tide it is less likely to be affected too much by the tide, but it is still very possible. Therefore both barnacles need to be protected from this. (Smith, 2013) Sun/Temperature: The acorn and brown barnacle need to be able to survive despite the sun and hot temperatures.
This adaptation is to retain moisture using a special structure – the operculum – which can be sealed when the snail is not eating to retain moisture within the shell. This is used especially between the high tides, as water only reaches this high zone at these times. Another factor associated with the supralittoral zone is harsh wind conditions, which was observed at Hastings Point where the temperature indicated a 12% increase in average temperature between the littoral and supralittoral zones. The black nerites adapted behaviourally to survive these conditions. To do this,
Sediment and nutrient pollution is a huge contributor to the poor water quality in the bay. While some nutrient variation is expected due to normal changes in weather,
They’re also tolerant of a broad range of environmental and climatic conditions, making them able to occupy many habitats. There are concerns that cane toads are the key factor in the decline of many native species. They endanger native frogs by consuming far more prey than them, approximately 200 food items per night, causing native frogs to need to compete for their food. They also possess highly toxic chemical predator defences which can kill many native predators, such as snakes and lizards that attempt to consume them (The biological effects, including lethal toxic ingestion, caused by Cane Toads).
A vulnerable species means if their their birth and deaths rates decrease, they will become endangered. Humans hunt Makos for sports and food(Gray, 2014). For example, they make shark fin soup with Mako sharks. To protect the Mako Shark species, they are protected by U.S. waters(Beardsley, 2015). Mako sharks are fascinating animals.
