Effect of climate Change on the Great Barrier Reef (GBR)

Rising sea temperatures: Empirical evidence shows that the rising temperatures caused by climatic changes have a ripple impact on the GBR due to the interdependence between algae found on the coral reef tissue and sea animals that feed on it (GBR Marine Park Authority, 2011). More importantly, rising temperatures stress coral reefs because they are highly responsive to fluctuating temperatures; in particular, if sea temperatures remain higher than usual overtime due to climate change, algae that depend on corals for food may escape the tissue. The effect of algae leaving the tissue is manifested when the corals change color ...

Rising sea temperatures

Rising sea temperatures are disturbing the ecosystem of the Great Barrier Reef, and if it continues, it will cause major disturbances in the coastal region. Temperature regulates the distribution and the variety of the marine life species, and it also maintains the growth of the coral reef. Over the years, these have grown and evolved with time. When a certain limit of the temperature is exceeded, it can cause the tiny algae inside to be expelled out which causes the coloration of the corals to change. The corals die because of this as they suffer from a lack of ...

The General Assembly of the United Nations has stated that “Changes to the climate, brought about by increasing levels of greenhouse gases in the atmosphere, will thus lead to changes in the oceans, including sea-level rise and ocean acidification, which will put marine ecosystems and coastal communities at risk. Most of these changes can be attributed to human activities and will negatively affect the animal inhabitants of the marine environment. Some effects of global warming on marine animals include changes in distribution, reduction of habitats and reductions in diversity and sex ratios. In the last hundred years, the rate ...

Improved scientific understanding in recent years has shown that humans are the major causes of climate change on the planet. A report released by IPCC (the UN Intergovernmental Panel on Climate Change) in 2014 reports that it is “extremely likely” that the dominant cause of global warming in the 20th Century is the influence of humans. Human activities over the last two hundred years, since the beginning of industrialization, have caused a building up of greenhouse gases in the atmosphere, and as a result, the Greenhouse Effect (a natural phenomenon which regulates the temperature of the earth) has increased ...

The majority of scientists are in agreement that global warming is occurring and is caused by human activities over the last two hundred years or so. Global warming is caused by the build up in the atmosphere of gases such as methane, carbon dioxide, nitrous oxide and others which have been created by the burning of fossil fuels in order to produce electricity, and for use in industries and motor vehicles. Another contribution to global is the removal of vast areas of natural forest from the planet. . The majority of carbon dioxide exchange between the atmosphere and the earth ...

BP Oil Spill had many negative effects to marine wildlife these effects occurred shortly after the instance while others occurred after the long run.

- This oil coated bird’s feathers and as a result many of the birds lost their buoyancy and capability to regulate their body temperature. Moreover, the oil concentration on the birds’ skin and face led to skin and eye lesions. Most of the birds died following this while the remaining few where infected with diseases. Birds require preening of their feathers so as to remain warm and dry, be able to remove parasites and remain ...

Introduction

The Florida area is renowned for its attractive and unique coral reef. The coral reef system that exists in this area serves as the natural habitat to many reef-dwelling species. Some of the well-known species are the Gag Grouper, which are considered very important to the fishermen. However, in the past 40 years, there has been a significant decrease in the coral reef cover in South Florida. It is estimated that over half of the native Oculina Varicosa coral that exists off the Florida coast has been ruined since the early 70’s, and there is very little evidence to ...

Impact of climatic change on the Great Barrier Reef

Climatic changes refer to lasting and significant changes in the weather patterns characterized by statistical distribution over a period spanning decades or hundred thousands of years. These changes may encompass extreme weather conditions and may happen due to variations in solar radiation reaching earth, biotic processes, volcanic eruptions, melting of the polar caps and plate tectonics. Certain activities undertaken by humans have also been recognized as contributing to negative climatic changes such as global warming. This climate change has threatened earth's ecosystems. The recent harsh change in the climate such as an increase in temperature takes a great toll on the ...

Causation of Climate Change

The world’s climate system is composed of five elements that include hydrosphere, lithosphere, atmosphere, cry sphere, and biosphere. It varies naturally with time and is dependent on the incoming and outgoing energy which determine the optimal balance of the earth’s energy. These determinants constitute factors that cause climate variation that result in either warmer or colder states. This result into a phenomenon referred to as climate change. This is a condition, in which, the earth experiences adjustments in its weather that occurs over a period. This essay provides a detailed analysis of the causes, characteristics, and the impacts of climate change ...

Glaucus atlanticus – a kind of gastropod mollusks from the unit of nudibranchs. Nudibranch called a large group of marine gastropods. These animals are related to the usual snails and slugs, but at the same time, nudibranchs have a number of unique anatomical features. For this reason, they are isolated in a special unit, which has about a thousand species. The general principle of the structure of these animals is the same as at the garden snails, the basis of body is flat foot-sole, at the anterior end of which there are stalked outgrowths - one pair carries at its ends tiny eyes, and the ...

Global warming has been a major climatic concern for a couple of decades. Many countries suffer from this menace either extremely or mildly. The effects of global warming is evident in agriculture, whereby crops do not thrive well as a result of it, and also affects the human population due to its numerous effects on human beings. This paper is going to focus on the cause as well as the effects of global warming and other fuel use in the UAE.

Causes of Global warming

There are many things that bring about global warming. They include; Emission of carbon dioxide gas by plants that use fossil ...

Tropical coral reefs are deep-sea habitat made of calcium carbonate. Corals secrete the calcium carbonate making most of the coral reefs. They occur in warm tropical waters with bountiful sunlight necessary for their survival. Coral reefs are made up of tiny marine creatures made up of few nutrients. Stony corals consisting of polyps make the basis for most of the coral reefs. Polyps belong to group cnidarians in the animal kingdom. This group of animals also consist the jellyfish and anemones. Different from the sea anemones, coral polyps secrete a hard exoskeleton made up of carbonate offering mechanical support to ...

Introduction

In its natural state, Carbon dioxide (CO2) is a colorless and odorless gas. Its significance in preserving life on Earth is demonstrated through Carbon cycle, a process that begins with the use of CO2 by plants for photosynthesis and ends with the release of the same compound into the atmosphere by the dead and decomposed plants and the animals that feed on them. This cycle is continuous and ensures that the supply of Carbon (a vital element of life) is sufficient. This paper, however, focuses on the disastrous effects of excessive CO2, released into the environment.

Overview

CO2, along with a ...

In evolution, medicine, as well as ecology, it is recognized that nature together with symbiotic interactions’ outcome are frequently context-dependent. However, the importance of context-dependence in symbiosis associated with diseases of wildlife. The availability of information that context-dependent symbiosis is important and common has resulted in evolutionary theory development, enhanced the apprehension of activity of bicontrol in agriculture and intensified the apprehension of ecologies of several species and contributed to human medicine. The authors of this paper reviewed the proof for context-dependency in symbioses, in various taxa, as well as disciplines. Symbioses are used as a variable, and chytridiomycosis, the ...

Introduction.

As mans impact on this pale blue dot with its complex and fragile natural cycles and ecosystems becomes increasingly more evident and concerning, it is up to the people to take initiative and pride themselves on minimising and hopefully one day in the far future reverse the harm we have caused to our one and only planet. It is due to our ignorance, greed and trust in the powers that be that have brought the climate to where it is today. So as conditions worsen we must hold governments accountable and implement strategies that protect natural systems whilst supporting ...

There are several ways in promoting the positive behaviors. One should have a solid ground of the support team that can guide them all throughout such as families, friends, and social groups. Aside from those, these healthcare programs such as Every Woman Matters Program, Black Corals' Project, and National Breast & Cervical Cancer Early Detection Program are also great help, to promote the positive behavior. Since, they are most expose to cancer incidence, so they come up with different techniques to motivate an individual. Providing supports that can certainly affect the behavior such as self-efficacy, social support, and problem-solving. But before ...

Biodiversity and sustainability, two of the major factors to determine if an ecosystem is habitable and sufficient for any life form, may it be fauna, fawn or human kind. However, there are only a few sites left around the globe which can be considered sustainable and contains biodiversity as climate change continues to affect the planet. Some areas have become barren, while a few remained arable but in the risk of being converted into commercial lands for homes or businesses. In the United States, the problem of pollution not only affected its once diverse ecosystem, which is considered the home of ...

About 70% of our planet’s surface is salt water, comprising five oceans. Of these oceans, the Pacific is the deepest; at its deepest spot almost 36,000 feet deep. It is also the largest, covering about a third of the earth’s entire surface, more than all five continents combined. As an important part of the world’s ecosystems, it has a surprisingly delicate balance, easily disturbed by man’s interference (intentional or otherwise) with the normal harmony of nature. For example, global warming and the consequent increases in temperature and CO2 levels are threatening marine life there. Many ...

Many scientists argue that oceanic acidification, which is said to arise from dissolving of artificial carbon dioxide emissions, has serious impacts to both the land and sea life. Besides, scientists equate oceanic acidification to the evils of global warming. However, in this essay, we argue that oceanic acidification does not pose much threat to either land or sea life, and it should not be such a significant environmental concern. Oceanic acidification, from artificial carbon dioxide emissions, is said to cause a decrease in PH level of the ocean, thus interfering with marine life. However, I refute this point because a decrease ...

Coral bleaching occurs when there is physiological stress experienced by the coral reefs. The stress is caused by an imbalance of the symbiotic relationship that the corals have with the algae that live within them. These algae are of the genus Symbiodinium. The algae are important to the coral reef since they are a source of nutrition and color. The algae will reduce or all will leave the coral reefs when there are harsh physical conditions. When this occurs, there is no tissue growth and sexual production in the corals. They end up losing color and thus the term coral ...

Coral Bleaching: Causes, Effects and Response Action Plan Coral bleaching occurs when there is physiological stress which leads to an imbalance of the symbiotic relationship that the corals have with the algae that live in the coral leaves (Rosenberg, Kushmaro, Kramarsky-Winter, Banin and Yossi 1). The algae will reduce or all will leave. The algae are important to the coral reef since they are a source of nutrition and colour. When this occurs, there is no tissue growth and sexual production in the corals. They end up losing colour and thus the term coral bleaching (Douglas, 386). The skeletal ...

Abstract
