Biodiversity and biodiversity indices essay

Intensified and enhanced food production through irrigation, use of fertilizer, plant protection pesticides or the introduction of crop varieties and cropping patterns affect biodiversity, and thus impact global nutritional status and human health. With this classification, Raunkiaer aimed to understand plants strategies to face cold climates.

Nevertheless, functional diversity studies may also focus on the importance of specific traits to individual fitness Bradshaw A relative of the vaquita, the baiji or Yangtze River dolphin, has not been sighted since and is presumed extinct. The idea of biodiversity also encompasses the range of ecological communities that species form.

During 70's, ecological researchers were mainly interested in understanding species interactions with biotic and abiotic factors Grime, leading to development of new approaches to organisms classifications Cummins ; Grime Biological sources provide many industrial materials.

The addition of rare species with one individual will fail to change the index. The Amazon basin, Madagascar and parts of southern and central Africa also compare favorably.

How is biodiversity measured? In oil palm plantations and other industrial-scale monocultures, a handful of standardized high-performance plant varieties produce huge quantities of agricultural commodities. It takes into account both richness and evenness. The value of this index also ranges between 0 and 1, but here, the greater the value, the greater the diversity.

Anyone can raise awareness: The greater the species diversity within an area, the higher the biodiversity, which can be calculated using various methods, such as diversity indices. How is biodiversity measured? For example, improved cultivation methods, suitable seed and agro-ecological strategies offer considerable potential to improve yields.

Such disturbances reduce the abundance of some organisms, cause population growth in others, modify the interactions among organisms, and alter the interactions between organisms and their physical and chemical environments.

What role does biodiversity play in conservation concepts? The areas with the greatest diversity of plant life are the tropical Andes and southeastern Asia. All of these hotspots are endangered by factors such as timber harvesting and slash-and-burn clearing driven by strong demand for tropical timber, the expansion of the mining industry and the cultivation of crops such as oil palms, sugar cane and soy.

Forest and prairie are just two of a plethora of names applied to ecological assemblages defined in a variety of ways, methods, and terms, and many ideas exist regarding what constitutes an assemblage. Again, only around 50 species of ants can be found throughout the UK.

Almost all the Hawaiian species, however, are found only there, whereas the species on continents may be much more widespread. Major processes affecting infectious disease reservoirs and transmission include, deforestation; land-use change; water management e.

Livestock feed is grown on an industrial scale on land that was once rainforest. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause political conflict.

So far, however, the plan only exists on paper. Unfortunately, biodiversity often takes a back seat when conservation measures are developed.


Increasingly sophisticated processes are then used to turn those raw materials into the seemingly endless variety of products on our supermarket shelves. It represents the wealth of biological resources available to us.

Biodiversity provides for variety of foods for the planet. It varies globally and within regions. Biodiversity What is biodiversity? Appropriate investment in renewable energy could threaten the fossil fuel industry though they are trying to adapt to that perhaps slowly, and after initial resistance.

Inthe terms threatened, endangered or rare were used to describe the status of many species. Biodiversity is determined by counting the number of species occurring in a given unit of area. The richness of functions and interdependencies in the relationships of species within ecosystems is also a factor.

Nonetheless, especially when these approaches are applied globally, as with the ecoregions used by the World Wide Fund for Nature World Wildlife Fund, WWFthey provide a useful guide to biodiversity patterns.

There are two versions of the formula for calculating D. The topic of placing a monetary value on nature as the basis of life was on the agenda in India in Hotspots are regions characterized by numerous endemic plant and animal species living in a particularly vulnerable environment.

Problems are thus continually being pushed further down the road without properly addressing them.Biodiversity provides numerous ecosystem services that are crucial to human well-being at present and in the future.

Climate is an integral part of ecosystem functioning and human health is impacted directly and indirectly by results of climatic conditions upon terrestrial and marine ecosystems. Biodiversity or Biological diversity is a term that describes the variety of living beings on earth.

In short, it is described as degree of variation of life. Biological diversity encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.

The data was analyzed for deriving various indices indicating biodiversity value, species richness and ecosystem uniqueness for different forest types. Table 3: The distribution of sample points in.

The Economics of Ecosystems and Biodiversity (TEEB) is an organization — backed by the UN and various European governments — attempting to compile, build and make a compelling economics case for the conservation of ecosystems and biodiversity.

Essay Indicators for Monitoring Biodiversity: A Hierarchical Approach REED F. NOSS* US. Environmental Protection Agency Environmental Research Laboratory Corvallis, ORU.S.A. Abstract: Biodiversity is presently a minor consideration in environmental policy. The data was analyzed for deriving various indices indicating biodiversity value, species richness and ecosystem uniqueness for different forest types.

Table 3: The distribution of sample points in each of the forest types.
