The word BIODIVERSITY originates from the Greek word BIOS = LIFE and Latin word DIVERSITAS = VARIETY or DIFFERENCE. The whole word BIO DIVERSITY generally therefore means: VARIETY OF LIFE.
What are the origins of biodiversity?
History of Biodiversity. … Charles Darwin  identified the first principle of the origin of modern biodiversity, namely that all species were linked in a single great phylogeny, or tree of life, and that all could be traced back to a presumed single original species at some distant time in the geological past.
What are the root causes of threats to biodiversity?
What are the main threats to biodiversity?
- Changes to how we use the land and waters. Both our lands and our seas contain many different ecosystems, and these are affected by business actions. …
- Overexploitation and unsustainable use. …
- Climate change. …
- Increased pollution. …
- Invasive species.
What is the original source of all biological diversity?
Genetic diversity in a population comes from two main sources: mutation and sexual reproduction. Mutation, a permanent change in DNA sequence is the ultimate source of new genetic variation in any population. An individual that has a mutated gene might have a different trait than other individuals in the population.
What are 3 causes of biodiversity?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.
Who made Biodiversity?
1980 – Thomas Lovejoy introduced the term biological diversity to the scientific community in a book. It rapidly became commonly used. 1985 – According to Edward O. Wilson, the contracted form biodiversity was coined by W. G. Rosen: “The National Forum on BioDiversity … was conceived by Walter G.
Who first introduced Biodiversity?
At the ecosystem level, India is also very well-endowed with 10 distinct biogeographic zones. In 1985, Walter G. Rosen first coined the term ‘Biodiversity’. It is a compound word of the longer form ‘Biological diversity’ which was coined by Lovejoy in 1980 to denote the number of species present in a group.
Where is the most biodiversity found on Earth?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
What are types of biodiversity?
Types of Biodiversity. Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).
What is the biggest threat to the loss of biodiversity?
Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
What is biodiversity Natgeo?
Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
When did biodiversity loss start?
Global Biodiversity Crisis
In the mid-1980s, the planet’s “biodiversity crisis” burst forth as a critical conservation issue at the National Forum on Biodiversity, organized in Washington, D.C., by the National Research Council and spearheaded by Harvard University biologist Edward O. Wilson.
What is the largest scale of biodiversity?
Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity.
