Environmental Effects On Marine Iguana

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.

The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.

In the article “Climate change in Hawaii and U.S Tropical islands” written by EPA, informs the audience that island communities and ecosystems face uncertainty as a result of the negative effects brought on by one of the most controversial topics debated today. Climate change. Islands, like Hawaii, Guam, and the Caribbean, are most vulnerable to the harsh effects of climate change. The reason for this is because islands are small and the way their infrastructures are set up make communities almost directly affected. One of the most important things that are affected is the weather. In areas where precipitation was generous, rainfall is actually decreasing while drier areas see an increase in rainfall. Less precipitation also means less available water resources because

The article discussed the changes in many habitats due to anthropogenic activity. Anthropogenic is an adjective that describes changes in nature due to the people. Next, this article discussed climate change and the impact that it is having on species like clams, and fish due to ocean temperatures rising. The article also addressed carbon dating of fossils to look for cause of extinctions. Human development and agriculture have had a tremendous impact on the population of many species that are terrestrial. Deforestation is a big problem that has caused a decline in the bird species. Commercial fishing in many areas has led to a decline in fish populations. Furthermore this article

Climatic changes are expected to change species distributions, phenologies, interspecific interactions, community composition, and ecosystem function (Schneider & Root 2002). Many of these impacts have already been observed (Parmesan 2006). In California’s San Joaquin Valley, temperatures are projected to be warmer in both winter and summer, with a mean annual increase of 1.4–2.0°C by 2070 (PRBO Conservation Science 2011). Additionally, precipitation is projected to decrease (-9% to -30%), although there is a high degree of uncertainty surrounding the magnitude of the precipitation changes (PRBO Conservation Science 2011). Summer heat waves are projected to become longer and hotter, and droughts more severe (Garfin et al. 2012).

Over the years, climate change has affected marine species because it has increased the ocean temperature, causing it to get warmer, which is causing a negative impact to most marine organisms like echinoderms and cnidarians (Quinn, 2016). In many cases, the optimum temperature of growth increased 1-6°C, which created harmful effects on stages of development (Quinn, 2016). In some cases such as the American lobster (Homarus americanus), warming of the ocean had caused smaller body sizes (Le Bris et al., 2016). Even though there is some research that showed that the warm temperature could also benefit the lobster’s population, most of their population has declined in the warmest and southernmost regions of the lobster’s range in places like southern New England and Long Island Sound (Quinn, 2016).

After watching the video on Finch evolution, and completing the gizmo, I have found many correlations between the finch population, and the climate of the Galapagos Islands. The Finches beak size was dependent on the climate, and natural selection. The population of the birds increased and decreased throughout the years because the extreme climate changes and the process of natural selection.

This scientific study is relevant to today’s issues in biology/society due to the constant progression of civilization. As time moves forward there is always something, whether it is an environmental factor or a societal one, that affects the progression of the human race. Humans are either braving impacts brought on by each other, or issues concerning their lifestyle. For example, climate change is a pressing matter due to the increasing temperature of the atmosphere. Eventually this could effect life as we know it by forcing populations to migrate to a cooler environment. This is similar to the reefs and their adaptation to seascape factors due to the fact that individuals acclimate to circumstances affecting them. The species present in

Climate change is one of the most important challenges of humankind in this century. The ability to adapt, mitigate and reduce carbon emissions will be decisive to preserve the world for future generations. The last IPCC report has provided more evidence regarding the rise in temperature and sea level. Apparently, additional 2°C above the pre-industrial average temperature levels is unavoidable, and it will continue at that level due the accumulation of gases in the atmosphere (Solomon 2009). Climate change will affect people all around the world in different ways, though the capacity to cope with it is different among regions and countries. The Latin America region is notably susceptible to climate change, due its geographical position, population location and its economy relying in natural resources (Vergara et. al. 2013a). The withdrawal of the coral biome, glaciers melting, jungles & forest savannization and strongest climate events are only some of the threats that will affect their inhabitants.

Have you ever wondered how the earth's processes have changed populations of organisms? Well, they can either drastically decrease or increase depending on what's happening in that area or environment.There are many people that would not waste time paying attention to things like these, but they should because you never know if it can affect you too. There are many ways the earth can bring up populations or destroy them such as specific resources, weather climate, finding preserved remains, or even when DNA strands change.

El Nino/ Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) have a major impact in the Pacific Basin. Understanding the different climate variability is relevant in order to have better knowledge on the marine living resources that we are dependent on. The equatorial Pacific and the coast of Peru are

"We call them dumb animals, and so they are, for they cannot tell us how they feel, but they do not suffer less because they have no words” (Anna Sewell). There is undeniable evidence that animals are being affected by climate change. Even though the effects are difficult to measure, there are many different ways animals are being affected. With the loss of predator and prey species it affects the life cycles in the food chain. The earth’s climate change causes habitats such as snow, ice, or forest areas to alter, resulting in loss of habitat and food accessibility as well as causing extinction.

Effects of climate change on marine mammals Introduction Climate change is the change in distribution of weather patterns usually after an extended period. Climate change is caused by factors such as variation in solar radiation, biotic processes, volcanic eruptions and plate tectonic oceans are known to be affected by climate. Marine mammals are very sensitive to changes in the ocean environment. It is anticipated that climate change effects on marine mammals mediated majorly by changes in prey distribution and abundance and the adaptable species may be able to respond to this changes to some extent. Observations made during the previous years on marine mammals show that certain species maybe vulnerable than others this may include those with limited habitat such as narwhals.

Global warming is a major problem when providing a suitable habitat and lifestyle for ample marine life. With sea levels rising there are consequences to plant life in coastal wetlands that can not handle the amount of water being provided. The wetlands are important in their job to protect the species they contain and for stabilizing coastlines. Storms are increasing in magnitude and severity, causing the transport of nutrients to marine life to be disturbed. As shores move further inland animals will have to move and adapt, history has shown how this can decrease populations. In the future both rare and abundant species could become locally extinct, with rare species on the verge of becoming totally extinct.
