Conservation biologists have designed a variety of objective means to measure biodiversity empirically. Each measure of biodiversity relates to a particular use of the data. For practical conservationists, measurements should include a quantification of values that are commonly shared among locally affected organisms, including humans. For others, a more economically defensible definition should allow the ensuring of continued possibilities for both adaptation and future use by humans, assuring environmental sustainability. As a consequence, biologists argue that this measure is likely to be associated with the variety of genes. Since it cannot always be said which genes are more likely to prove beneficial, the best choice for conservation is to assure the persistence of as many genes as possible. For ecologists, this latter approach is sometimes considered too restrictive, as it prohibits ecological succession. (Wikipedia).
31. Why So Many Species? The Factors Affecting Biodiversity
Principles of Evolution, Ecology and Behavior (EEB 122) One can look at biodiversity from several perspectives. An ecological point of view tries to determine how necessary diversity is for an ecosystem to function. An economic point of view tries to capture the value of the "services"

An ecosystem can be defined as a large, highly interconnected area of the planet that is composed of several different biotic and abiotic components. A good example of an ecosystem would be an entire forest or mountain range. A natural ecosystem is made of all the plants, animals, and en

👉 Learn how to find the variance and standard deviation of a set of data. The variance of a set of data is a measure of spread/variation which measures how far a set of numbers is spread out from their average value. The standard deviation of a set of data is a measure of spread/variation

The Missing Pieces in the 6th Mass Extinction
Recent biodiversity reports point to a drastic drop in species across the world, but on the local scale the results are more mixed. We're also missing data from some of the key ecosystems on our planet. In order to fight off the 6th mass extinction, we need more data to get a complete pict
