Systems ecology

drives all environmental and ecosystem management decisions are sustainability. Sustainability is defined by Miller & Spoolman, (2009) as the “Ability of earth’s various systems, including human cultural systems and economies, to survive and adapt to changing environmental conditions indefinitely.” Applying this definition to ecology, there are four scientific principles of sustainability that highlight how the ecosystem has naturally sustained itself for billions of years. The thought by…

Clayton Hull-Crew stated, “When one animal is removed, specifically a powerful player in its ecosystem, not only does their niche become available, but many others collapse. Every spot occupied in a system relies on every other. Waterfowl rely on frogs and tadpoles for food, those frogs spawn in still waters provided by beavers, and beavers rely on flora to eat and use as building materials. That fits the usual bottom-up model of ecosystems, but who…

over the world are suffering from the results of the projects, which are made for the name of progress in today’s industrial society. The way to such type of thinking is offered by the theory of ecocriticism which has various concepts such as deep ecology, ecopoetics,and ecofeminism. Ecofeminism encourages our interconnectedness with nature. It also addresses the subjugation of women and marginalized people. The recognition of social and environmental injustices is presented…

Journal Two: Leopold Aldo Leopold’s The Land Ethic mainly focuses on the importance of developing a sort of ethic for interacting with the land or a symbiotic relationship with the land and the world around us. This piece touches on numerous aspects of our current relationship with the environment and what needs to be reformed and understood in order to improve this relationship. Although The Land Ethic was published in 1949, Leopold’s statements and evaluations made in this piece are…

cannot metabolize large loads of glucose (MacDonald et al., 1984; Zoran, 2002). Hence, they fully depend upon gluconeogenesis to obtain energy for maintaining their blood glucose level from glucogenic amino acids and glycerol. The sugar transport systems in the feline intestinal brush border are non adaptive to varying levels of dietary carbohydrate (Buddington et al., 1991). However, D-glucose transport across the…

including their species richness in an environment. It is a major component of environment and useful for all living organisms including man. Biodiversity plays important role in regulation of climate. Biodiversity is a major part of life-support system. It is particularly ecological, economic, spiritual, cultural, and aesthetic importance. Although the benefits from biodiversity, present causes to species and ecosystem diversity are the greatest recorded in recent period. All these threats are…

Sustainability Importance Student’s Name Bethel University The Importance of Sustainability The importance of sustainability is simply a matter of taking care of the earth and everything thereof. Religion plays its own significant part in sustainability also. If we as a people do not learn to take care of the land, animals, and the things in nature, we jeopardize losing our ozone layers and running out of fossil fuels. In addition, people and animals can become extinct, we could lose our…

Sustainability is concerned with the promoting of the most effective use of resources, the protection of the environment and ecosystems and the development of a more equitable world society. As sustainability includes different issues, is often difficult to define precise terms of it. Considering the Venn diagram, sustainability can be described as the intersection of three main issues as environmental, economic and social issues. Sustainability Venn diagram…

reproductive output, and experiencing virtually almost no predation of their own, due to their possession of large, venomous dorsal, pelvic and anal spines (Arias-González JE and al. 2011). These factors make the invasive red lionfish a compelling system to study species interactions with native fish communities Since their…

Five Research Articles on Biodiversity Succession in Ecology: Summaries Article 1: “Effects of nitrogen deposition on soil and vegetation in primary succession stages in inland drift sands” What kind of system was being considered? -They studied the Inland drift sands in the areas of the Netherlands. They specifically looked and studied at the Drethe, Veluwe, Utrecht, Brabant, and along Meuse. They wanted to consider how plants grow and develop during succession. The author’s hypothesis: -The…
