There is local biodiversity, which directly impacts daily life, affecting the availability of fresh water, food choices, and fuel sources for humans. Regional biodiversity includes habitats and ecosystems that synergizes and either overlaps or differs on a regional scale.
It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour, or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined.
The higher biodiversity there is within an ecosystem, the higher the chances are that species richness will be prevalent with respects to the ecosystem's relative abundance levels. Species richness across different parts of the world will show variations based on location, climate, predator/prey relationship, food availability and other factors ...
Two global information systems are either dedicated to, or have strong focus on, biogeography (in the form of the spatial location of observations of organisms), namely the Global Biodiversity Information Facility (GBIF: 2.57 billion species occurrence records reported as at August 2023) [29] and, for marine species only, the Ocean Biodiversity ...
This classification is used to define the Global 200 list of ecoregions identified by the WWF as priorities for conservation. [ 27 ] For the terrestrial ecoregions , there is a specific EcoID, format XXnnNN (XX is the biogeographic realm , nn is the biome number, NN is the individual number).
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
Biodiversity is usually plotted as the richness of a geographic area, with some reference to a temporal scale. Types of biodiversity include taxonomic or species, ecological, morphological, and genetic diversity. Taxonomic diversity, that is the number of species, genera, family is the most commonly assessed type. [7]
Taxonomic rank is a classification level in biological taxonomy, such as species, genus, family, order, class, phylum, and kingdom.
