  2. Limiting factor - Wikipedia

    en.wikipedia.org/wiki/Limiting_factor

    Limiting factor. A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. A factor not limiting over a certain domain of starting conditions may yet be limiting over ...

  3. Liebig's law of the minimum - Wikipedia

    en.wikipedia.org/wiki/Liebig's_law_of_the_minimum

    In a limited system life will adjust as an evolution of what came before. Biotechnology. One example of technological innovation is in plant genetics whereby the biological characteristics of species can be changed by employing genetic modification to alter biological dependence on the most limiting resource.

  4. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    The best-known example is the so-called "paradox of the plankton". All plankton species live on a very limited number of resources, primarily solar energy and minerals dissolved in the water. According to the competitive exclusion principle, only a small number of plankton species should be able to coexist on these resources.

  5. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    Competition (biology) Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory ). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other.

  6. Shelford's law of tolerance - Wikipedia

    en.wikipedia.org/wiki/Shelford's_Law_of_Tolerance

    A low level of one factor can sometimes be partially compensated for by appropriate levels of other factors. In case of chemical reactions it is known as law of limiting factor. A corollary to this is that two factors may work synergistically (e.g. 1 + 1 = 5), to make a habitat favorable or unfavorable. Geographic distribution of sugar maple.

  7. Carrying capacity - Wikipedia

    en.wikipedia.org/wiki/Carrying_capacity

    Carrying capacity. The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the environment 's maximal load, [clarification needed] which in population ...

  8. Population control - Wikipedia

    en.wikipedia.org/wiki/Population_control

    Population control is the practice of artificially maintaining the size of any population. It simply refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology. [1] [2] [3]

  9. Marginal distribution (biology) - Wikipedia

    en.wikipedia.org/.../Marginal_distribution_(biology)

    Marginal distribution (biology) The geographical limits to the distribution of a species are determined by biotic or abiotic factors. Core populations are those occurring within the centre of the range, and marginal populations (also called peripheral populations) are found at the boundary of the range. The inability of a species to expand its ...
