Conservation biology is reforming around strategic plans to protect biodiversity. [ 203 ] [ 208 ] [ 209 ] [ 210 ] Preserving global biodiversity is a priority in strategic conservation plans that are designed to engage public policy and concerns affecting local, regional and global scales of communities, ecosystems and cultures. [ 211 ]
The genetic diversity within species is one of the three fundamental components of biodiversity (along with species diversity and ecosystem diversity), [1] so it is an important consideration in the wider field of conservation biology.
The Convention on Biological Diversity (CBD), known informally as the Biodiversity Convention, is a multilateral treaty. The Convention has three main goals: the conservation of biological diversity (or biodiversity); the sustainable use of its components; and the fair and equitable sharing of benefits arising from genetic resources.
[3] [4]: 5 [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. [5] "Ecosystem processes" are the transfers of energy and materials from one pool to another. [2]: 458 Ecosystem processes are known to "take place at a wide range of scales". Therefore, the correct scale of study depends on the ...
Another study, published in 2011 by PLoS Biology, estimated there to be 8.7 million ± 1.3 million eukaryotic species on Earth. [11] Some 250,000 valid fossil species have been described, but this is believed to be a small proportion of all species that have ever lived. [12] Global biodiversity is affected by extinction and speciation.
Biogeography (an amalgamation of biology and geography) is the comparative study of the geographic distribution of organisms and the corresponding evolution of their traits in space and time. [146] The Journal of Biogeography was established in 1974. [147] Biogeography and ecology share many of their disciplinary roots.
The concept of the natural environment can be distinguished as components: Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms , soil , rocks , plateaus, mountains, the atmosphere and natural phenomena that occur within their boundaries and their nature.
Common components of different classification schemes were used to allow users to navigate using multiple classifications and to meander among schemes. This initiative overcame a major problem of many biological data bases, [ 13 ] that of having rigid and singular classification structures that were unable to reflect the diversity of views, or ...
