functions together to keep the organism alive and functioning well. The scope of the biology includes the study of all these and may extend to the level of the organism such as behavior‚ and the organism mechanism for interacting with its environment. Ecology started from the study of the organism-a group of organisms that is similar in appearance‚ behavior and genetic make up belong to the same species. The biological species concept state that members of a species are those individual that are genetically

Exotic plant invasions are causing profound changes to ecosystems around the world. However‚ it is difficult to generalise about their effects on ecosystem properties‚ since these vary according to the traits of the invading species‚ and the properties of the invaded vegetation and habitat. Yet‚ knowing the inherent functional traits of an exotic invasive plant could improve understanding of its invasion success and impact‚ since plant traits affect ecosystem properties such as through fall distribution

Introduction The state of the world today is under a great amount of stress. This is mainly due to the evolution of man and their usage of the space they inhabit (Nickerson 2003). Due to humans increasingly invading and destroying natural areas‚ current environmental problems are induced and they include: global warming‚ acid rain‚ air pollution‚ waste and deforestation (Nickerson‚ 2003). These issues have a detrimental effect on more than a handful of species and ultimately cause a reduction in

In September‚ I began “Let’s Map‚” a school-yard mapping and species identification project‚ and “Living Machine Stewards‚” where students maintained the school’s Living Machine and increased the biodiversity of this model aquatic ecosystem. In the winter‚ students in the “For the Birds!” program created a bird viewing and feeding station. ts an example of sustainable developmwnt because it It aims to raise the level of environmental awareness among teachers and students

We have recognized the problem and developed a strategy to balance the ecosystem‚ with causing harm to the environment‚ the people of our cities‚ and to our cities commerce. Ecosystem balance is very important. It is the equilibrium and harmonious coexistence

survival fitting machine. In the beginning of the film it shows two professors describing a creature who has evolved into the “most extreme and deadly” of species. The creature they are talking about becomes identified as the “Newt”. Newts are aquatic amphibian creatures’ part of the Salamander family. In the scheme of predator and prey‚ the newt is known as the prey and its opposite is considered the garter snake. As a defense mechanism to the garter snake the newt produces a toxic nerve poison

Biodiversity is the variability among living organisms from all sources‚ including terrestrial‚ marine‚ and other aquatic ecosystems and the ecological complexes of which they are part of‚ this includes diversity within species‚ between species‚ and of ecosystems. Biodiversity in animals have changed over time whether it has been through genetics or adaptations from outside forces‚ such as ecosystems. The question that has been through multiple assumptions and have been approached many times is:

stumbling blocks which we are encountering with in our international effort to achieve sustainable development. 2. What is sustainable development To start with this concept I prefer to define ecology in the first step since it is related to sustainable development. According to Ernst Haeckel “Ecology is the study of our physical environment; more precisely the study of distribution and abundance of organisms and also the relationships between these organisms with their physical environment (Cary
