Techniques to Assess Animal Diversity: Faunal Diversity Assessment

Background

At the beginning of the present century, was an expressive study of nature, a sort of natural history, which drew inspiration from the works of explorers and naturalists. Biodiversity is well-defined as the variability among living organisms from all sources, including, terrestrial, marine, other aquatic ecosystems, the ecological complexes of which they are part this contains diversity within species, between species and ecosystems (OECD, 2014). Biodiversity has evolved over the last 3.8 billion years or so of the planet’s approximately 5 billion-year history. Although five major extinction events have been recorded over this period, the large number, variety of genes, species and ecosystems in existence today are the ones with which human societies have developed, and on which people depend. As the basis for all ecosystem services, and the foundation for truly sustainable development, biodiversity plays fundamental roles in maintaining and enhancing the well-being of the world’s more than 6.7 billion people, rich, poor, rural and urban alike. Biodiversity comprises much of the renewable natural capital on which livelihoods and development are grounded biodiversity, encompassing variety and variability of all life on earth, is the product of over 3.5 billion years of evolutionary history. A process of assessment of existing status and change in the condition of biodiversity, as measured against a set of criteria and indicators. The faunal biodiversity to be assessed at species level, ecosystem level and genetic level. The oldest method to assess faunal diversity were direct count and indirect count.
