Many aspects of lionfish biology are studied at the USGS Wetland and Aquatic Research Center. Patterns pertaining to the geographic distribution of organisms and patterns in the fossil record played a fundamental role in convincing Darwin and other scientists that evolution had happened, and they still play an important role today in providing insights into the evolutionary process. Consequently, admixture patterns may vary by geographic regions ranging from countries to neighborhoods. Biogeographic studies divide Earth's surfaceprimarily the continents and islands into regions exhibiting differences in the average composition of flora and fauna. This is discussed below under geographical distribution and host range. These geographic distribution records will be accepted in a standard format only, and all authors must adhere to that format, as For example the IUCN describes the geographical range of Pan troglodytes as wide but discontinuous across Equatorial Africa between 13 degrees North and 7 degrees South occurring from southern Senegal across the forested belt north of the Congo River to western Uganda and western Tanzania from sea-level to 2 .

The settings in which leishmaniasis is found range from rain forests in Central and South America to deserts in West Asia. Biogeography is the study of the geographic distribution of living things and the abiotic factors that affect their distribution. Different ecological and evolutionary factors such as the dispersal ability, tolerance to environment changes, population size, floral phenotypic plasticity, establishment and extinction dynamics may help to explain the geographic distribution of species (Brown et al., 1996).But breeding systems have been often viewed as a factor that may affect the persistency and distribution .

There are 54-75 species of true mangroves, which are found only in the intertidal zones of coasts, and are taxonomically isolated from terrestrial counterparts. Geographic isolation refers to the separation of members of a population by a physical barrier, such as a mountain or body of water, which disrupts the gene flow between them and begins the process of speciation. noun : the natural arrangement and apportionment of the various forms of animals and plants in the different regions and localities of the earth Love words?
