Biodiversity is the variation in living forms and can be measured in ways that include the number of species, functional variety of species, evenness of species distribution or genetic diversity. Biodiversity science investigates levels of biodiversity, its functional effects, and how and why it changes over time.
Why do we research biodiversity?
Genetic diversity within species is a useful measure of biodiversity, because many species are divided into local populations that are uniquely adapted to the environments in which they live . The study of the causes and consequences of such local adaptations is an important part of population biology.
What defines biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems , and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What is biodiversity in simple words?
Biodiversity is the shortened form of two words “biological” and “diversity” . It refers to all the variety of life that can be found on Earth (plants, animals, fungi and micro-organisms) as well as to the communities that they form and the habitats in which they live.
What is biodiversity study?
Biodiversity studies comprise the systematic examination of the full array of different kinds of organisms together with the technology by which the diversity can be maintained and used for the benefit of humanity.
What is biodiversity example?
Biodiversity is the variety of life . Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. ... Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
What is the aim of biodiversity?
The aim of Biodiversity is to raise an appreciation and deeper understanding of species, ecosystems and the interconnectedness of the living world and thereby avoid the mismanagement, misuse and destruction of biodiversity.
Why do humans rely on biodiversity?
Humans depend upon biodiversity for survival , such as for the foods we eat, medicines we use to stay healthy, and materials we wear or use to build our homes. These services are the tangible products or items that we and other species con sume for survival.
What are the major threats to biodiversity today?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation .
What is the difference between nature and biodiversity?
What is the difference between nature and biodiversity? The difference is very simple: nature covers all existing systems—created at the same time as the Earth —whereas biodiversity is the part of nature that is alive, born on a mineral substrate, in an earlier geodiversity.
What are the types of biodiversity?

What are the 4 types of biodiversity?
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. ...
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. ...

What do you call a person who studies biodiversity?
Who studies biodiversity? Biodiversity and biodiversity conservation is studied by scientists in several fields. These include ecologists , zoologists, botanists, biogeographers, and geneticists, with each exploring the subject from different perspectives and with different hypotheses.
What are the main principles of biodiversity?
We propose an alternative approach based on a set of five guiding principles for biodiversity conservation that are broadly applicable to any forested area: (1) the maintenance of connectivity; (2) the maintenance of landscape heterogeneity ; (3) the maintenance of stand structural complexity; and (4) the maintenance of ...
Who does biodiversity benefit?
- Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play.
- Support a larger number of plant species and, therefore, a greater variety of crops.
- Protect freshwater resources.
- Promote soils formation and protection.
