Ecosystems are complex and ecological indicators can help describe them in simpler terms that can be understood and used by non-scientists to make management decisions. For example, the number of different beetle taxa found in a field can be used as an indicator of biodiversity. Many different types of indicators have been developed.
There are many ways to measure biodiversity within a given ecosystem. However, the two most popular are Shannon-Weaver diversity index, [4] commonly referred to as Shannon diversity index, and the other is Simpsons diversity index. [5] Although many scientists prefer to use Shannon's diversity index simply because it takes into account species ...
This is a list of biodiversity databases. Biodiversity databases store taxonomic information alone or more commonly also other information like distribution (spatial) data and ecological data, which provide information on the biodiversity of a particular area or group of living organisms. They may store specimen-level information, species-level ...
Data from 2018 found that at 1.5 °C (2.7 °F), 2 °C (3.6 °F) and 3.2 °C (5.8 °F) of global warming, over half of climatically determined geographic range would be lost by 8%, 16%, and 44% of plant species. This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria. [41] [42]
A biological indicator is also the name given to a process for assessing the sterility of an environment through the use of resistant microorganism strains (e.g. Bacillus or Geobacillus). [5] Biological indicators can be described as the introduction of a highly resistant microorganisms to a given environment before sterilization , tests are ...
Biodiversity is the result of 3.5 billion years of evolution. [106] The origin of life has not been established by science, however, some evidence suggests that life may already have been well-established only a few hundred million years after the formation of the Earth .
2016 conservation indicator which includes the following indicators: marine protected areas, terrestrial biome protection (global and national), and species protection (global and national) Conservation biology is the study of the conservation of nature and of Earth 's biodiversity with the aim of protecting species , their habitats , and ...
In natural ecosystems, the greatest utilization of carbon is through the uptake of carbon in photosynthesis and the second greatest utilization of carbon is through the release of carbon in cellular respiration. [5] minute changes to these two fluxes can have a larger effect on the carbon dioxide in the atmosphere. [6]
