  2. Coupled human–environment system - Wikipedia

    en.wikipedia.org/wiki/Coupled_human–environment...

    The phrase "coupled human–environment systems" appears in the earlier literature (dating back to 1999) noting that social and natural systems are inseparable. [ 7 ] [ 8 ] "In 2007 a formal standing program in Dynamics of Coupled Natural and Human Systems was created by the U.S. National Science Foundation."

  3. Open system (systems theory) - Wikipedia

    en.wikipedia.org/wiki/Open_system_(systems_theory)

    In the social sciences an open system is a process that exchanges material, energy, people, capital and information with its environment. French/Greek philosopher Kostas Axelos argued that seeing the "world system" as inherently open (though unified) would solve many of the problems in the social sciences, including that of praxis (the relation of knowledge to practice), so that various social ...

  4. Gene–environment interaction - Wikipedia

    en.wikipedia.org/wiki/Gene–environment_interaction

    Gene–environment interaction (or genotype–environment interaction or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. [ 1 ]

  5. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    Ecosystem ecology is the "study of the interactions between organisms and their environment as an integrated system". [ 2 ] : 458 The size of ecosystems can range up to ten orders of magnitude , from the surface layers of rocks to the surface of the planet.

  6. System context diagram - Wikipedia

    en.wikipedia.org/wiki/System_context_diagram

    Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.

  7. Cell–cell interaction - Wikipedia

    en.wikipedia.org/wiki/Cell–cell_interaction

    Cell–cell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the ...

  8. Gene-environment interplay - Wikipedia

    en.wikipedia.org/wiki/Gene-environment_interplay

    Gene–environment interaction occurs when genetic factors and environmental factors interact to produce an outcome that cannot be explained by either factor alone. [6] For example, a study found that individuals carrying the genetic variant 5-HTT (the short copy) that encodes the serotonin transporter were at a higher risk of developing depression when exposed to adverse childhood experiences ...

  9. Biological interaction - Wikipedia

    en.wikipedia.org/wiki/Biological_interaction

    Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
