Invasive species are any species that is not native to a specific ecosystem (7). The majority of people believe that invasive species are harmful; causing economic damage‚ disrupting ecological food webs‚ and out competing native species for food and land. The benefits of invasive species are overlooked and tossed aside by many people. Invasive species have the ability to control other species populations/ problems in an ecosystem‚ create biodiversity‚ and help in testing for cures for diseases and

Conservation 2 Earth is composed of many different ecosystems and each one is a “dynamic complex of plant‚ animal‚ and micro-organism communities interacting with the non-living environment as a functional unit" (Protecting Threatened Ecosystems‚ 2004). These ecosystems are an intricate part of the human lifecycle as they provide us with our water‚ food and energy. Since mankind is in a take and take some more relationship with the ecosystems‚ many of them have had their natural processes disrupted

ABSTRACT An ecosystem is a very important part of our natural world. Everything relates to nature in one way or another. In turn‚ should be treated with respect and should be not tampered from its original state. With animal annihilation and extinction aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population

Within planet earth today Biodiversity forms the foundation for the vast array of ecosystem services that critically contribute to human well being. It is as important in human managed ecosystems as well as natural ecosystems (Hambler‚ C.‚ 2004‚ 15). To begin to understand Biodiversity

Keystone species play a large role in each ecosystem‚ they have the ability to alter their ecosystem or be the reason they completely collapse. Keystone species are the reason that many different species exist‚ these other species highly depend on the keystone species for survival‚ if a single keystone species were to go extinct‚ it is likely for other species populations to decrease. Other species benefit from keystone species in a variety of ways‚ such as food supply‚ shelter‚ or a water source

However many of these ecosystems are threatened by the likes of climate change‚ increased urbanisation/land use and tourism developments which can prove critical for the wellbeing of their environment. One area that has witnessed degradation in recent years is Galapagos which

rapidly growing knowledge base of ecosystem services provided by landscape features. Although the conventional approach to landscape ecology is based on a model that assumes poor ecological quality in the human-dominated matrix‚ a review of recent literature reveals important opportunities to improve the quality of the landscape matrix by increasing spatial heterogeneity through the addition of seminatural landscape elements designed to provide multiple ecosystem services. Taken alone‚ these individual

However‚ when based in the indices on Diversity‚ Similarity and Dominance in the tropical grassland and tropical rainforest data‚ the Simpson Indices favor the data for the tropical rainforest as more diverse than the tropical grassland. The Simpson Indices‚ as defined in Cuevas et. al (2012)‚ is based on dominance and as the number of dominant species in a community are few‚ the species has low diversity. The tropical rainforest ecosystem showed a higher index of
