Recommended: Impact of invasive species on ecosystems research paper

According to T.N. Ananthakrishnan (2010), the definition of biodiversity can be as the variety of life on earth at all its levels which are from genes to ecosystems and the ecological and evolutionary processes that sustain it. The most diverse group of organisms on earth is insects and related arthropods. They make up more than 95% of animal diversity globally and considered as an important component of biodiversity (Neher, 1999; Giller, 1996).
The estimation of total global biodiversity is about 80 million species. Invertebrates represent most of these while most invertebrates are arthropods and most arthropods are terrestrial insects (Giller, 1996). Soil microbial community contributes to diversity of insects through plant diversity. Insect diversity is also play a role in contributing to diversity of plant. This is because the abundance and richness of plant species can be strongly influenced by insects during insect outbreaks. It eventually limits the fitness and abundance of certain plant species (Bennett, 2010). Additionally, the composition of the soil community can be chang...

    First of all I would have to say that yes it has a great impact on our global warming and I will go on to explain to you how it affects our planet. We as a whole have let the dollar get in the way of how our planet is affected, some would say at all costs. It is true we have refineries, car pollution, but most of all deforestation of tropical areas. In the National Geographic Magazine you will come to see and appreciate the facts of how deforestation has affected our nation and has spiraled into global warming. We can look at Brazil’s rainforest that is estimated to be larger than two hundred football fields it will be destroyed before you are even able to read the article at hand (Magazine, 1996-2014). It has been noted that within the past 40 years we have managed to do more damage than what was done in the four hundred and fifty (450) years since the European Colonization even began. That sent chills through my bones when I read that, imagine how much tropical areas have been affected. We have destroyed twen...

  • Macro Ecology Essay

    1623 Words  | 4 Pages

    Discerning the spatial patterns of biodiversity and understanding their ultimate (why) and proximate (how) causes is very dear to biogeography and is one of the key concepts of Macro ecology. Some places on earth contain more species as compared to others. All species occurring at a given space and time either originated (speciated) there or dispersed and arrived from another place and settled there. Biogeographers try to understand the past and current distributions of species by incorporating historical, evolutionary and ecological factors. Earlier biogeographers or the ‘naturalists’ in their sacred quest to serve ‘the creator’, travelled to various parts of the world and imparted valuable knowledge about the diverse patterns and processes of nature. Linnaeus (1743), on the one hand, hypothesized that early Earth was filled with water except for it’s highest mountain top i.e., Mount Ararat which was known to be the site of paradise and as the sea level dropped the exposed land was colonized by plants and animals that migrated down from high elevational zones of Mount Ararat whereas Willdenow (1805) hypothesized that within each geographical region of the earth, plants and animals were first placed and later survived the great flood on many mountain ranges (Lomolino,2001). Von Humboldt and Darwin in the South American Andes and Wallace Southeast Asian islands noticed the decreasing trend in elevational species richness patterns (McCain and Grytnes, 2010). Later work done by Grinnell (1917), Whittaker (1952), Terborgh (1977, 1985) on elevational species richness became accepted and set a established pattern for all species for more than two decades (McCain and Grytnes, 2010). However current researches on elevational gradients are...

    Deforestation is defined as the clearing of trees, and the absence of a forest. What most people seem to turn a blind eye to the fact that we need these trees and plants not just for our paper, pencils, or even furniture, but something much greater than any of these things put together. Indeed having a low costly grocery store within walking distance is pleasant, but there are negative consequences as well as positive consequences that coincide with the placement of a Wal-Mart in the city of Oviedo. It is understood to many that industrialization as well as being able to finally have a store that does not charge six dollars for orange juice is a blessing. Fretfully, the negative consequences will

    Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?

    Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth

    In The Diversity of Life, Edward O. Wilson reflects on how the living world became diverse and how humans are destroying that diversity. In the book’s preface, Wilson defines biodiversity as “the totality of inherited variation in all organisms in a selected area” (Wilson ix). He adds that modern technology will allow for us to find many new species that were previously unknown to be in existence.

  • The Degradation of Ecosystems and Loss of Biodiversity

    940 Words  | 2 Pages

    Biodiversity is affected by five main pressures: habitat loss and degradation, climate change, excessive nutrient load and pollution, over-exploitation, and invasive alien species. As mentioned before, humans are not the only force that influences the environment. Natural events such as volcanic eruptions can potentially disrupt an ecosystem’s balance as well. However, at least three out of five of the principle pressures are caused by humans, although it is arguable that we do play a crucial role in speeding climate change and transporting invasive species. Ecosystem degradation and biodiversity loss is almost like the result of the other issues.

  • Loss of Biodiversity

    998 Words  | 2 Pages

    One of the reasons for loss in biodiversity is alteration of habitats. A habitat is the natural environment in which a species of living organism lives. If the habitat of a species is changed, it will cause the species to die or migrate to other places where it can find its natural habitat. There are many ways in which the habitat of plants and animals can be altered. One of them is land use changes. Since the beginning of human life, human beings have been changing land use for farming. Large areas of forests have been cleared by humans to increase the area of farming to satisfy their growing needs. Many biodiversity-rich landscape characteristics have been lost due to intensive farming (Young, Richards, Fischer, Halada, Kull, Kuzniar, Tartes, Uzunov & Watt, 2007). For example, traditional farming was replaced by private farms in Europe after the First World War causing an immense change in land use patterns. Another major proble...

    According to Campbell and Reece (2007) biogeography is the study of the past and present distribution of species. Cristopherson (1994) states that it is the study of the distribution of plants, animals and related ecosystems and the geographical relationships with related environments over time. It involves a wide range of disciplines such as biology, geology, geography and ecology. It begs the question, why are there so many more species in tropical rainforests than in woodlands? What allows a species to live in one area and prevents it from dispersing and colonising in other areas?

    NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY:         Biodiversity, a contraction of “biological diversity,” generally refers to the variety and variability of life on Earth. The very existence of human species and sustainable development depend on biodiversity conservation, therefore the need for conservation of biodiversity is basically for this reason that all living creatures need other creatures and plants in one way or the other. At least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are mainly derived from biological resources. Biodiversity is necessary for our existence as well as valuable in its own right as it provides the fundamental building blocks for the many goods and services which are essential
