: the natural arrangement and apportionment of the various forms of animals and plants in the different regions and localities of the earth .
What is geographical distribution of the population?
Population distribution means the pattern of where people live . World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people.
What is an example of geographic distribution?
Geographical distribution is the natural arrangement of animals and plants in particular regions . For example. wild potatoes are found in significant numbers along the west coast of South America and Central America. ... In other instances animals from the same species, get seperated, and therfore grow in different places.
What are the two types of geographic distribution?
Usually the natural geographical distribution is stated, naturalised and cultivated distribution is given only if the natural distribution is unknown or obscurely known.
What causes geographic distribution?
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.
What are 6 types of distribution patterns?
- Uniform dispersion. In uniform dispersion, individuals of a population are spaced more or less evenly. ...
- Random dispersion. In random dispersion, individuals are distributed randomly, without a predictable pattern. ...
- Clumped dispersion. In a clumped dispersion, individuals are clustered in groups.
What is geographical isolation?
The physical separation of members of a population . populations may be physically separated when their original habitat becomes divided. Example: when new land or water barriers form. See also allopatric speciation.
What are the geographical factors that influence the distribution of population?
The main factors determining population distribution are : climate, landforms, topography, soil, energy and mineral resources, accessibility like distance from sea coast, natural harbours, navigable rivers or canals, cultural factors, political boundaries , controls on migration and trade, government policies, types of ...
What parts of the world have high population distribution?
The territories in the world with the highest population densities are Southeast Asia, Western and Central Europe, and the east coast of the US . Other areas are located along some river valleys, such as the river Nile, the coast of Brazil, Mexico and Maghreb, and also areas rich in mineral or energy resources.
What do you understand by geographical distribution of diseases?
The relationship between the prevalence of a disease and specific geographical-environmental conditions . For example, goiter occurs in inland iodine-deficient areas of the U.S., and pulmonary hypertension occurs in those who reside at high altitude.
Why is random distribution so rare?
Random distribution is rare in nature as biotic factors , such as the interactions with neighboring individuals, and abiotic factors, such as climate or soil conditions, generally cause organisms to be either clustered or spread. ... Random distributions exhibit chance clumps (see Poisson clumping).
What are the characteristics of geographic distribution?
Geographic distributions are thus a function of a range of morphological and physiological adaptations of individual organisms , characteristics acquired through the process of natural selection.
What is the most common type of distribution?
The most commonly used distribution is the normal distribution , which is used frequently in finance, investing, science, and engineering. The normal distribution is fully characterized by its mean and standard deviation, meaning the distribution is not skewed and does exhibit kurtosis.
What are geographical changes?
A sequence of actions, natural and/or cultural, that shape and change environments, places and societies. Some examples of geographic processes include erosion, migration, desertification and globalisation .
What does the word geographic?
1 : of or relating to geography . 2 : belonging to or characteristic of a particular region the geographic features of Ohio. Other Words from geographic More Example Sentences Learn More About geographic.
What causes clumped distribution?
Clumped patterns usually occur when resources are concentrated in small areas within a larger habitat or because of individuals forming social groups . At large spatial scales most organisms appear to have clumped distributions because their habitats are not uniformly distributed over wide areas.
