Climate Change and the Bottlenose Dolphins

The rise of sea levels are projected to increase warmer waters from one and a half to two degrees in Central North Pacific in 2050, 1.9 to 2.6 degrees in Northern Islands, and also two to five degrees in the Caribbean at the end of this century. This rise of temperature decreases the life of ecosystems in the ocean and resulting in less freshwater for

As the earth's global temperature rises, the ocean is expected to encroach upon population-dense coastal areas because of melting permafrost and the thermal expansion of the water. When water in rivers cannot flow into the

A warming ocean has already killed large chunks of Australia’s Great Barrier Reef. On April 4, 2017, writer Eduardo Porter for The New York Times published an article called, “To Curb Global Warming, Science Fiction May Become Fact,” intended for the reader of the New York Times. The editorial talks about how if we don’t take action as soon as possible, climate change could indeed become a new thing. Scientist all over the world are discovering many areas throughout the planet that are increasing in temperature, and animals’ homes are being destroyed. The writer is able to create a better understanding on the dangers of a warming planet, by saying the earth is increasing in temperature all over the world, not only affecting different animals,

Modern fishing methods have first and foremost created serious problems for ocean ecosystems. Scholastic Scope states, “The populations of almost all fish species that we eat have shrunken, some drastically, as a result of overfishing, or catching fish faster than they can reproduce” (Dignan 14). Sadly, fish cannot reproduce fast enough to sustain their populations when different fishing techniques drain their ecosystem’s health. Because humans are relatively new organisms, fish, a much older species, have not adapted to modern fishing techniques and overfishing in the sea. Therefore, oceans are at risk because fish cannot compete with newer, more efficient fishing techniques produced by humans. Climate change is furthermore another major threat to oceans. As published by Scholastic Scope, “Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems” (Dignan 14). Although climate change may now be a controversial issue, its footprint and effects have no doubt left their mark. Powerful and destructive climate change has also been the culprit of extinction for many other animals such as the marine animals during the Permian-Triassic extinction event. Since things often repeat itself in history, the ocean could have a Holocene extinction event, which would completely

Bottlenose dolphins are among the most familiar cetaceans, just as whales. The Bottlenose dolphin is a primitive member of the subfamily Delphinine. Bottlenose dolphins are grey, varying from dark grey at the top near the dorsal fin to very light grey and almost white at the underside. There are two ecotypes of bottlenose dolphins the coastal and the offshore. The Coastal dolphin has a small body and large flippers to increase agility and heat dissipation. They have a limited movement into offshore waters and like shallow warm water near the shore. Coastal dolphins for the most part remain in their region. The Offshore dolphin has a large body to help conserve heat and defend itself against predators. They are less restricted in range and movement and like deep, cold waters. Offshore dolphins in the North Atlantic have migratory patterns that follow prey distribution. Bottlenose dolphins live in groups typically of 10–30 members, called pods, but group size varies from single individuals up to more than 1,000. In a case study performed by Randall Wells who is the leader of the longest study of dolphin population since 1970, it was discovered that there are three main factors that influence migration: Seasonal changes in prey location, predation pressure and reproductive requirements. (Wells, 1980). In the fall dolphins follow mullet fish when they migrate from the bays into the Gulf of Mexico to spawn. Dolphins experience the most predation pressure during the summer when

Global warming is affecting oceans and seas, they temperature is increasing and is becoming higher the concentrations of carbon dioxide, making the oceans more acidic, Is impacting the coral reefs, the are at risk, there are dying, and important fact is that in 2050 is the global warming remain, the coral will die, including the animals that live in there. The oceans and seas are becoming worst, animals are dying for temperature or by the contamination that humans produce. Contamination effect to Global warming. The temperatures are becoming worse every year.

Global warming is the number one concern on the planet right now (Ankara 1). Ankara University suggests that “the most common definition of global warming is the process in which Earth’s temperatures increase due too many human activities” (“The Impact of Global…” 1). A basic background of how climate change is provoked is that it is caused by fossil fuels and carbon dioxide being released in the air due to many human activities. This event can potentially harm the human population and put many ecosystems around the world to extinction. Marine ecosystems, in general, are parts of the Earth’s hydrosphere, which make up large parts of the Earth and contain magnificent biodiversity from beautiful fish to the

A one way trip taking two weeks longer than the other. This was explained with the global ocean conveyor current loops. Global temperatures are rising because of gases like carbon dioxide, methane, and others. Penguin and polar bear population are suffering because of these changes. These changes potentially could stop the ocean currents causing an ice age. Ultimately, this will have an effect on upwelling creating a problem for fish populations. Furthermore, anoxia and sulfide eruptions can have a big toll on the ocean food chain. Mass die off of sea life is becoming more common and unless climate change is stopped they will become more

The oceans have been recorded to be rising in surface temperature, which in turn is causing fish to migrate to colder oceans near the poles; this disruption fisheries and other animals who prey on fish. The rise in temperature also can control currents, which caused a 40% increase in tropical storms since the 1950’s. The rise in temperature in our atmosphere has also caused for the melting of the ice caps, which has raised the sea levels almost 6.7 inches in the last century, with some locations on the eastern parts of Canada reading increases as high as 8 inches. These readings are more than double what they were in the previous century. The acidity of oceans is also increasing due to the increase of CO2 in the air. This is doing many things to different ecosystems such as coral reefs. The Great Coral Reef in Australia has lost half of its’ coral over the last 27 years alone. The rise in temperature and carbon dioxide causes the coral to bleach, which makes it weak and allows it to be destroyed very easily by any storms, or other predators. The rise in carbon emissions not only affects land life, but is also destroying our oceans as

Millions of dollars have been invested into vet care and machines to help with the care of dolphins, including x-rays, scales, and better suited habitats. In recent findings by Larry Schaefer, it has been shown that dolphin lifespans have actually increased by living in captivity. This is mainly because of the constantly monitored lives of the mammals, and because of the near to zero threat level. Having no predators in captivity guarantees them safety, however an unnatural life. (Schaefer,

The bottlenose dolphin has a broad diet that varies depending on its water depth. Those that live inshore typically feed on fish and other invertebrates located near the shoreline. Deepwater, bottlenose dolphins, on the other hand, typically feed on squid and fish in pelagic zones. Furthermore, bottlenose dolphins have differing diets depending on their geographic location. Bottlenose dolphins along the U.S. Atlantic Coast typically feed on the following: atlantic croacker (micropogonias undulatas), spot fish (Leistomos xanthurus), and silver perch (Bairiella chrysoura), whereas those found in South Africa typically feed on: african massbankers (Trachurus delagoae), olive grunters (Pomadasys olivaceus), and pandora (Pagellus bellotti). The

The next innocent animal forced to cope with global warming is the whale. With the ocean waters warming more and more, the patches of zooplankton that female whales need to “bulk up” for a full pregnancy and being able to produce milk for her young. When the amount of zooplankton is too low, the right whale,

The animal that I choose was Bottlenose Dolphin, but if you want it scientific name is considered as a Tursiops. Bottlenose dolphins are mammals so they are warm-blooded just like human. There are so many things to talk about this species like what they do during their environment and learn about their life cycle. It is great that I am learning about my favorite animal and it turns out that dolphin are never separated from their families. Bottlenose dolphins are very joyful that like kids would want to swim with them and play around.

This article talks about how the Arctic Ocean is being affected by climate change. Because of greenhouse gas emissions, the PH of the water is lowering, its glaciers are melting which is causing a rise sea levels, and many species are becoming vulnerable. A mineral called aragonite, which is a form of calcium carbonate, is found in the water and helps organisms build their exoskeletons. As the Arctic’s water becomes more acidic, it loses more and more of this mineral, which threatens the lives of plankton, coral reefs, and shell-fish. The Artic is most vulnerable to acidification because northern ocean currents push the Pacific’s water into the Artic, which contains certain chemical properties that lead to lower pH. After much research, scientists

Marine biologist play a key role in understanding climate change and identifying sustainable and profitable ways humans can use the sea and its resources. Marine biologist understand marine organisms needs in their habitats, ultimately helping protect species and reduce human threats. As experts in understanding marine habitats, marine biologist often form essential parts of relief teams. They respond to oil spills and chemical leaks, helping other scientist restore normalcy to local habitats. Sometimes, marine biologists influence other spheres, such as economics and law. They might analyze the effect of sonar on whales and seals, for instance, recommending best practices for reducing harm on those sensitive populations. Marine biologists understand how the ocean supports basic needs, and in turn relay that information to lawmakers, who establish protocols regarding human use of ocean waters and marine organisms. Marine biologist help develop ocean technology too, improving waste elimination, energy sourcing and extraction of key sources. A brief review of components of the marine environment, world food resources, climate control, air and water quality, transportation, and the ecosystem balance are important features that are studied by marine biology. So, understanding why marine biology is important is foundational to integrating a balanced approach toward management of the sea and proper stewardship of organisms,
