Biologists most often define biodiversity as the "totality of genes, species and ecosystems of a region". [8] [9] An advantage of this definition is that it presents a unified view of the traditional types of biological variety previously identified: taxonomic diversity (usually measured at the species diversity level) [10]
There is biodiversity of marine species in the sea where nutrient cycles are common. A picture of the Udachnaya pipe, an open-pit diamond mine in Siberia. An example of a non-renewable natural resource. Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics ...
The physiognomic approach in the study of vegetation is common among biogeographers working on vegetation on a world scale, or when there is a lack of taxonomic knowledge of someplace (e.g., in the tropics, where biodiversity is commonly high). [14] The concept of "vegetation type" is more ambiguous. The definition of a specific vegetation type ...
A 2019 UN report assessing global biodiversity extrapolated IUCN data to all species and estimated that 1 million species worldwide could face extinction. [ 38 ] [ 39 ] Conservation of a select species are often prioritized on several factors which include significant economic and ecological value, as well as desirability or attractiveness. [ 40 ]
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 ...
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]
A lion (Panthera leo).Lions are an example of charismatic megafauna, a group of wildlife species that are especially popular in human culture.. Wildlife refers to undomesticated animals and uncultivated plant species which can exist in their natural habitat, but has come to include all organisms that grow or live wild in an area without being introduced by humans. [1]
Biodiversity declines can lead to associated declines in ecosystem services. A long-term study reports the decline of 74–92% of catch per unit effort of sharks in Australian coastline from the 1960s to 2010s. [70] Such biodiversity losses impact not just species themselves, but humans as well, and can contribute to climate change across the ...
