Biotone
A biotone is a biogeographical region characterized not by distinctive biota but rather by a distinctive transition from one set of biota to another. They often contain the limits of distribution of the biota of neighbouring regions. Biotones are especially useful in marine biogeography, where the movement of water may result in substantial overlap in the floral and faunal components of adjacent regions. In such case, the regions of overlap is considered a biotone. A simple example would be mid-latitude waters where tropical and temperate waters mix. This region is a biotone characterized by the transition between tropical and temperate waters. It would contain both tropical and temperate biota. Tropical biota that do not extend into temperate areas would be at the limit of their range in this biotone, and vice versa. The co-occurrence of biota that are normally distinct can result in unusual ecological relationships. References Biogeography {{ecoregion-stub ...

Biogeography
Biogeography is the study of the species distribution, distribution of species and ecosystems in geography, geographic space and through evolutionary history of life, geological time. Organisms and biological community (ecology), communities often vary in a regular fashion along geographic gradients of latitude, elevation, allopatric speciation, isolation and habitat species-area curve, area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable Natural environment, environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy (bio ...

Biota (ecology)
A biome () is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. In 1935, Tansley added the climatic and soil aspects to the idea, calling it '' ecosystem''. The International Biological Program (1964–74) projects popularized the concept of biome. However, in some contexts, the term ''biome'' is used in a different manner. In German literature, particularly in the Walter terminology, the term is used similarly as '' biotope'' (a concrete geographical unit), while the biome definition used in this article is used as an international, non-regional, terminology—irrespectively of the continent in which an area is present, it takes the same biome name—and corresponds to his "zonobiome", "orobiome" and "pedobiome" (biomes determined by climate zone, altitude or soil). In the Brazilian literature, the term ''biome'' is sometim ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Marine (ocean)
The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as ''oceans'' (the Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic Ocean),"Ocean."
