24 Οκτ 2024 · Biodiversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety, called species richness, is the count of species in an area. Biodiversity encompasses the genetic variety within each species and the variety of ecosystems that species create.
31 Μαΐ 2019 · Biodiversity is a term which describes every living organism within a single ecosystem or habitat, including numbers and diversity of species and all environmental aspects such as temperature, oxygen and carbon dioxide levels and climate.
10 Μαρ 2023 · Biodiversity is defined as the measurement tool for all the variations (at all three levels namely genetic, species, and ecosystem) that exist in the different life forms inhabiting the Earth’s surface. It includes all microscopic and macroscopic forms of life. Why Is Biodiversity Important?
Summary. Biodiversity includes not only the world's species with their unique evolutionary histories, but also genetic variability within and among populations of species and the distribution of species across local habitats, ecosystems, landscapes, and whole continents or oceans.
Biodiversity refers to the ecological complex formed by living organisms (including animals, plants, and micro-organisms), the surrounding environment, and the sum of various ecological processes related to them, including ecosystem diversity, species diversity, and genetic diversity [1].
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.
We synthesize aspects of this literature, focusing on several key concepts, debates, patterns, trends, and drivers. We review the history of the term and the multiple dimensions and values of biodiversity, and we explore what is known and not known about global patterns of biodiversity.
