A variety of objective means exist to empirically measure biodiversity. Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness ...
Whether the ecological unit is perceived as a "real" entity or an abstraction by an observer: This argument debates if an ecological unit, despite having a name and loose definition, whether it is simply a measure for conceptual thought that helps in modeling, or whether it is definitive and seen as a concrete thing.
A diversity index is a method of measuring how many different types (e.g. species) there are in a dataset (e.g. a community).Diversity indices are statistical representations of different aspects of biodiversity (e.g. richness, evenness, and dominance), which are useful simplifications for comparing different communities or sites.
Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.
Biodiversity is also known to have an important role in reducing disaster risk and in post-disaster relief and recovery efforts. [167] [168] Biodiversity provides critical support for drug discovery and the availability of medicinal resources.
The Report examined the rate of decline in biodiversity and found that the adverse effects of human activities on the world's species is "unprecedented in human history": [14] one million species, including 40 percent of amphibians, almost a third of reef-building corals, more than a third of marine mammals, and 10 percent of all insects are ...
It has not been common for companies to integrate biodiversity aspects into their value chain, but some companies and organizations have shown overall efforts for implementing better practices. [4] An existing example for guidelines on biodiversity practices in agriculture is the Biodiversity Action Plan for spice production in India. [5]
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an intergovernmental organization established to improve the interface between science and policy on issues of biodiversity and ecosystem services. [47] [48] It is intended to serve a similar role to the Intergovernmental Panel on Climate Change. [49]
