Web4 de set. de 2024 · Biological diversity, or biodiversity, refers to all of the variety of life that exists on Earth. Biodiversity can be described and measured at three different levels: species, genetic, and ecosystem diversity. Species diversity refers to the number of different species in an ecosystem or on Earth as a whole. Neutral genetic diversity consists of genes that do not increase fitness and are not responsible for adaptability. Natural selection does not act on these neutral genes. Adaptive genetic diversity consists of genes that increase fitness and are responsible for adaptability to changes in the environment. Adaptive genes are responsible for ecological, morphological, and behavioral traits. Natural selection acts on adaptive genes which allows the organisms to evolve. The rate of evol…

WebDiversity can be measured by considering species richness, the Shannon index, or Shannon entropy. The data on biodiversity are incomplete or insufficient to provide a complete picture.
