Environmental Factors : The Environmental Effects Of Marine Populations

Climate change has affected us in many ways, but it was even more influential on organisms and their community. The Earth is gradually heating and we are left to deal with the consequences. Homes are being destroyed, organisms are dying, and resources are running low. Since 1880, Our Earth’s temperature had increased by about 0.8 degrees Celsius. Climate change is affecting the Earth and scientists say that one more degree will greatly affect people from all over the world. There are many consequences of climate change and each one has a great impact on all of us, but organisms’ homes are being destroyed and thousands of species are dying out. These organisms are imperative to our world and how it functions.

Unforeseen weather that reduces soil moisture levels and increases water temperatures would affect all of the four organisms I picked. In the algae population, this species would not be able to intake enough oxygen to grow, therefore, this population would suffer. Moreover, warmer water temperature would affect the feeding behavior of the ghost shrimp, starfish, and shark population. For example, the ghost shrimp would not have enough algae plants to feed upon, therefore, they would starve, which would lead to domino effect throughout the ecosystem. In addition, all of the three species reproduction schedule would change, thus, they would not be able to reproduce as many offspring as they would in a normal environment. This would lead to less

Any change to an environment can be harmful to a species and often changes the carrying capacity in that area. In the case of an increase in temperature, the North American River Otter and the Giant Pacific Octopus are both impacted. There would likely be negative effects to both species, but the Giant Pacific Octopus’ ability to adapt more quickly in a warmer environment gives it an advantage in this changing environment. While the River Otter would have many detrimental changes occur with an increase in temperature, the octopus may have an increased chance of survival.

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

Natural selection is arduous but it is also amazing to see how some aquatic organism evolved over time with pollution and specifically global warming. Since global warming will increase heat in aquatic habitat, thermal behavior will evolve as well (Bolnick 2003, et al). Ectothermal species are very fascinating due to their capability to live in a wide variety of climate change on earth. Knowing about their ability would explain their tolerance even though we are going through a big climate change every day (Sollid 2006). As a conformer Carassius auratus would not mind being within a range of different environment without too much suffocation as long as it’s not over their limit. Being responsive to climate change would have an

Increasing temperatures are an immediate threat to the earth and its many diverse ecosystems. Our group chose to take an in depth look at the effects of climate change on freshwater fish species, specifically on the rising air and freshwater temperatures and how they affect a cold water dwelling fish species such as the trout. We will explore how the distribution of trout has changed over time with rising temperatures, how fires due to climate change affect trout populations, and lastly what the economic impacts of increased water temperatures will be on fisheries.

The example given is the coral trout, a fish that is commercially important. Since the water temperature has risen higher up in the water, these trout tend to be more lethargic now; they stay lower in the water. This is crucial because all of their hunting and mating ground is higher

Increasing water temperatures decrease the amount of phytoplankton, which is what shrimp eat. As the water temperature increases it takes a ripple effect into the marine ecosystem, phytoplankton decrease in numbers, shrimp decline in numbers, those that prey off of shrimp decline and so on (Trotter). This then leads species to migrate to stable habitats, but survival of the fittest takes into place and large amounts die off in the process.

In general, the rate of physiological processes increase as the temperature and oxygen concentration increase (Buentello et al., 2000). The main controlling factor for fish or shrimp feeding, metabolism, and growth is temperature. The growth rate is reduced if the energy demand of increased metabolic rate exceeds the gain from increased food consumption (Brett, 1979). When the food supply is not limiting, the specific growth rate of most aquatic species increases with rising temperature (Talbot,

The Natural Bridges at Santa Cruz that I have been to study the marine organisms and the environment of between the beach and the ocean. The directions to the Natural Bridges Tide Pool Area is at the north end of 2395 Delaware Ave and De Anza Trailer Park. We examine some different kinds of marine plants such as seaweeds, kelps, and algae in texture, size, type of phylum and class, and how tidal zone affects their natural habitat. We learn about different animals that different in their biodiversities such as Epifauna and Infauna animals. We also examine and analyze the data in abiotic living things about the intertidal habitat. We also observe the tidal zone in high, middle, and low from how winds carried the energy to create the ocean waves.

Serge M. Garcia and Andrew A. Rosenberg expect that global warming will affect the “availability, stability, access and utilization of food supplies” (2010). This will have important consequences for an already constricted system. Rising water levels will affect the habitat of ocean and land dwellers. The availability of fish will be altered as species acclimated towards warmer water migrate towards the poles, due to increasing water temperature (Garcia and Rosenberg, 2010). Ocean acidification is the foremost critical effect of global warming on the oceans. It results from the absorption of atmospheric carbon dioxide by the oceans, which lowers the pH of the water. The National Oceanic and Atmospheric Administration (NOAA) of the US states that there has been about a 30% increase in ocean acidity since the beginning of the industrial revolution. Moreover, current CO2 output levels would lead to a 150% increase in ocean acidity by the end of this century (NOAA). Increased ocean acidity will have drastic effects on shellfish and coral, due to their calcium based nature (NOAA). Reduced quantities of shellfish and coral will further alter presently dwindling habitats and amplify the loss of biodiversity. Garcia and Rosenberg explain that temperature changes will greatly affect fish’s metabolism, growth, and reproduction because they are cold-blooded. This will further influence the availability of food and the

The effect of increasing ocean temperatures is important to understand because the rising temperatures influence the physiology, ecology, distribution and evolution of marine life. Marine biologists have observed changes in cell physiological processes, protein damage to membrane fluidity, relocation of marine species, and species extinction since the sea temperatures have risen. Marine life also faces greater susceptibility to infectious diseases due to climate change. Distribution and abundance of marine life food sources have also been affected by warmer ocean temperatures.

There are many concerns for marine organisms and ecosystems. These concerns include: reduced calcification rates, increased photosynthesis and nitrogen fixation, reduced growth, production, and life span of adults juveniles and larvae, reduced tolerance to other environmental fluctuations, and significant shifts in key nutrient and trace element speciation. This creates changes to fitness and survival, species biogeography, key biochemical cycles, and food webs. It also creates reduced sounds absorption, homing ability, and recruitment and settlement.

As the world develops and the human population grows there is more pollution being dumped into the oceans, causing major problems to marine life and ecosystems. Major causes of marine pollution involve non-point pollutants, marine garbage, toxic ocean pollutants and sewage disposal in oceans. From heavy metal poisoning including lead and mercury killing predators such as sharks and whales, to waste getting trapped in the digestive tracts of marine animals, this essay focuses on how human interference causes horrifying problems to the marine life, but also how to fix it. It will also explore the normal activities of people including farming and how this can cause an imbalance in an ecosystem. Everyday activities can cause massive nutrient

It is well known that approximately 40% of the world’s population lives within 100km of a coastline. Knowing this fully well goes to explain the effect which this population have on the coastal area and the coastal resources (Segal 1997). Generally, coastal population exerts enormous pressure on the marine environment and its resources due to seeking out a livelihood, it is also documented that a considerable percentage of the economy comes from the activities, occupations, and livelihood that really either directly or indirectly on marine resources and several other factors that are present there(Small, Gornitz & Cohen 2000). As a result of this, issues arise from conflicting uses of marine resources either through man’s interaction with the marine environment causing pollution and depletion of resources or through man’s interaction with fellow man giving rise to a dispute over use of space, unauthorised use and exploiting of resources (Cicin-Sain et al. 1998). All these activities, according to (Douvere 2008) have “considerably increased the demand for ocean space and it is certain that this will continue to be so in the future”.
