Aquatic ecology

The public's attention has recently been caught by species introduction and its resultant biotic invasions which are major components of global change. The last few decades have seen substantial advancements in invasion ecology which are succinctly summarised in this book. The deliberate or accidental introduction of organisms into a new ecosystem may cause the onset of a biological invasion. These so-called 'exotic species' may establish, spread and ecologically alter the invaded community.…

Bioindicators and How They Aid Scientists in Preserving Environments Kira Seckler 11/18/15 Bioindicators are everywhere, from the pond in your backyard to a tree in a forest, and they all help us by doing the same thing, changing. What are bioindicators and in what ways are they useful in environmental preservation? Bioindicators help us and scientists maintain a…

In the article, “Why Bother” by Michael Pollan, we see him discuss many arguments on why we should do our part in going green. His inspiration to start living green was inspired by Al Gore’s An Inconvenient Truth. He discusses that many people are aware of the rapid environmental changes, but feel that it is too late to take action. I don’t believe that is true. There are many ways we can contribute to environmental preservation that he explains throughout the article. Some of these was…

THE GREENS The party established in 1992 has four elemental significance i.e. ecological sustainability, social justice, grassroots democracy and peace and non-violence. The party tries to maintain fair trade deals which can keep the transparency going in order to maintain peace and build trust. The Greens are not enthusiastic about the trade agreements that are taking place as these trade agreements according to them are not keeping in mind all the environmental factors and are only interested…

Once common, this species has started to decline across much of its range from Queensland to northern NSW; it is most commonly found in Southern Queensland, in places such as Hervey Bay, Sunshine Coast and Moreton Bay. Its preferred habitats are tidal rivers and the intertidal flats of estuaries and bays, which are lined with mangroves and have sandy to muddy bottoms. The population decrease has been caused from a combination of habitat degradation, mortality from commercial and recreational…

Lesson 2.1 Which type of business takes resources from nature to make its products? Name several examples. The business that gets their resources from nature is Extractors. Some examples are oil refineries and mines. Oil drillers extract oil from the ground then it is used as a resource. Miners also get coal and other minerals from nature and use them for goods. Why is raising capital critical to success of a business? Raising capital is critical to a business. Without capital there would not…

Post Lab 3 – Ecosystem Management: The Oak Savannah at High Park 1. The upper ravine slope of High Park’s oak savannahs consist primarily of black and white oak, shrubs, wildflowers, and grasses. These ecosystems also have very dry and sandy soil, which has caused the oaks to adapt to low soil nitrogen availability levels. Furthermore, the plants found in these savannahs are dependent on frequent fires to clear out the invasive species so they do not have to compete for light and also to sustain…

Over the past century we have seen not only our population skyrocket, but also our technological capacity increase exponentially. My worldview, primarily eco-centric, is focused on the incredible potential of technology to create sustainable harmony between humanity and the earth. We have gotten to a point in our evolution where it will be impossible to revert to our pre-industrial state. Our resources are limited and should not be wasted, this traces back to the fundamental property of the…

Why is Stewardship Important Today? Stewardship is important today as it is necessary for the survival of living organisms, it helps set a good example for generations to come, and God called us to be stewards of creation. It’s vital to preserve God’s creation because if we don't look after the planet and sustain it, and if we continue to exploit and abuse our power over the environment, our world’s natural resources will eventually run out. Even though it may be hard, it is important to nurture…

Many species of plants and animals may seem attractive, but looks can be deceiving. Various kinds of plants and animals are brought in each state intentionally or accidentally. They are introduced intentionally by people for specific purposes such as to serve as pets or to fulfill the responsibilities of native species. They could also be introduced accidentally, because of increasing trade, by ocean voyaging ships, or other means. According to the National Oceanic and Atmospheric Administration…
