Species naturally migrate and expand their ranges, utilising new habitats and resources, e.g. the cattle egret.These natural invasions, an incursion in the absence of anthropogenic influences, occur "when an intervening barrier is removed, or through the development of biotic or abiotic transportation mechanisms, able to overcome the barrier in question". [3]
The full title of the 10th edition (1758), which was the most important one, was Systema naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis, which appeared in English in 1806 with the title: "A General System of Nature, Through the Three Grand Kingdoms of Animals ...

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."
The open systems are systems that allow interactions between its internal elements and the environment. An open system is defined as a "system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components." [4] For example, living organism. Closed systems, on the other hand ...
The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
Ecocentrism (/ ˌ ɛ k oʊ ˈ s ɛ n t r ɪ z əm /; from Greek: οἶκος oikos, 'house' and κέντρον kentron, 'center') is a term used by environmental philosophers and ecologists to denote a nature-centered, as opposed to human-centered (i.e., anthropocentric), system of values.
Holarchy: A concept invented by Arthur Koestler to describe behavior that is partly a function of individual nature and partly a function of the nature of the embedding system, generally operating in a bottom upwards fashion. Holism: A non-reductionist descriptive and investigative strategy for generating explanatory principles of whole systems.
