Jan 3, 2021 13: biogeographic diversity biogeography is the study of the distribution of organisms in space and through time.
The patterns of biogeography are the result of the interaction between the two great engines of our planet: evolution and plate tectonics. Because it faces such wide-ranging questions, biogeography must draw upon an extensive range of other disciplines. Explaining biodiversity, for example, involves the understanding of climate patterns over the face of the earth, and the way in which the productivity of photosynthetic plants differs with climate and latitude.
Today, biogeography is broken into three main fields of study: historical biogeography, ecological biogeography, and conservation biogeography. Each field, however, looks at phytogeography (the past and present distribution of plants) and zoogeography (the past and present distribution of animals).

A large majority of the species are endemic to a seep area and the symbiont-containing species are mainly endemic to the cold-seep ecosystem. A comparison of species found in other deep chemosynthesis-based ecosystems, hydrothermal vents, whale carcass and shipwreck reduced habitats, reveals from the existing data, that only 13 species, of which five are symbiont-containing species occur, at both seeps and hydrothermal vents.

Here, we review our current state of knowledge about the biodiversity and biogeography of the atmosphere, with an emphasis on micro-organisms, the numerically dominant forms of aerial life. We present evidence to suggest that the atmosphere is a habitat for micro-organisms, and not purely a conduit for terrestrial and aquatic life.
Biogeography is the study of the geographic distribution of living things and the abiotic (non-living) factors that affect their distribution. Abiotic factors can include temperature, moisture, nutrients, oxygen, and energy availability, as well as disturbances from events such as wind and fire.

Biogeography is the study of the distribution of organisms in space and through time. Analyses of the patterns of biogeography can be divided into the two fields of historical biogeography and ecological biogeography (wiley, 1981). Historical biogeography examines past events in the geological history of the earth and uses these to explain patterns in the spatial and temporal distributions of organisms (usually species or higher taxonomic ranks).
Biogeography is the geographical distribution of organisms and how and why that changes over time. It is closely linked to the study of biodiversity, or the number of different organisms in a specific area.
