Biodiversity What is Biodiversity? Biodiversity describes the variety of different types of life found on Earth. It is extent of the variety of organisms present in different ecosystems. This can denote to genetic variation, ecosystem, variation, or species disparity (number of species) inside an area, biome, or planet. Biodiversity is pondered at three levels:- 1. Genetic 2. Species 3. Ecosystem • Genetic Diversity Variation amongst the same species between diverse groups and between versions
Studies showed that the elimination of sea otters during the 1800s from the Californian waters might be responsible for the dwindling numbers of kelp forests. Further studies have also shown that the population density of sea otters affects seaweed biodiversity as well. In a study conducted in Alaska on three different bays, the Torch Bay, Deer Harbor and the Surge Bay, it was found that the presence of sea otters led to a decrease in the population of sea urchins, which led to an increase in the population
utilizing Alachua County’s property. PC b states that conservation easements are “likely to provide tens of millions of dollars of value to the public in the form of forest ecosystem services” (pp 18).One of the goals of the Envision plan is to provide Alachua with recreation, aesthetics, and cultural use through 23, 216 acres of conversation easement while also addressing the rivalry of those goals with resources management and private use. While conservation will diminish resource utilization for private
Urbanization Among the many human activities that cause habitat loss (Czech et al. 2000), urban development accounts for some of the greatest local extinction rates and frequently eliminates the large majority of native species (Vale and Vale 1976, Luniak 1994, Kowarik 1995,Marzluff 2001). Also, urbanization is often more continous than other types of habitat loss. Throughout much of New England, for example, ecological succession is restoring forest habitat lost from farming and logging, whereas
Therefore, sea otters play an indirect, yet vital role in the preservation of kelp forests. This in turn protects kelp forests and other macroalgae, which would have otherwise been depleted due to grazing by sea urchins. “Where sea otters abound so do
second category, there are three conservation statuses which are “critically endangered”, “endangered” and “vulnerable”. They differ in the risk of extinction; “critically endangered” species has the highest risk of extinction, followed by the remaining two. The third category consists of 3 conservation statuses: “conservation dependent”, “near threatened” and “least concern”, which differ from one another in terms of their needs to be included into conservation programs. By understanding the risk
lousy effect governed the environment. People have finally realized that man and nature should be interdependent and that the economy and the environment must develop together. All of the negative impacts on the environment have either direct and indirect adverse effects on the long-term economy. Deforestation not only affects the environment, but it also negatively affects the long-term economy as seen through impacts on forest ecology, timber production, and intangible goods. Forest is one of the
or real conservation concern? Abstract: Invasive plant species are a cause of great concern in many countries of the world due to their impact on the environment, the economy and on human health. The movement of these plants across borders have been facilitated by global trade and travel. Invasive alien species are non-native plants that are introduced in new areas causing drastic changes to the natural habitats, thus threatening the indigenous plant species and impact local biodiversity. Although
Proposed Botanical Garden Design Prepared by: Date submitted Section Name of TA Introduction Biodiversity refers to the variety of life species that exist on the Earth. Studies on diversity include understanding the relationship between all the living species on Earth The Importance of Biodiversity According to (Newmark, 2010), to the people on Earth and the health of ecosystems, biodiversity is vital for the following mentioned reasons; it helps us to live healthy and happy through the provision
Biodiversity Introduction For once in history, the introduction of a foreign species has had paramount importance throughout their evolution for many terrestrial ecosystems. Apis Mellifera also commonly known as the Western Honey bee, is a vital component to global biodiversity. The honey bee provides ecosystem services of considerable ecological significance for the reproduction of plants and for the pollination of many economically important crops. Although the place of origin of Apis Mellifera
