Systems ecology is an interdisciplinary field of ecology , a subset of Earth system science , that takes a holistic approach to the study of ecological systems, especially ecosystems . Systems ecology can be seen as an application of general systems theory to ecology. Central to the systems ecology approach is the idea that an ecosystem is a complex system exhibiting emergent properties . Systems ecology focuses on interactions and transactions within and between biological and ecological systems, and is especially concerned with the way the functioning of ecosystems can be influenced by human interventions. It uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems.
73-430: Systems ecology seeks a holistic view of the interactions and transactions within and between biological and ecological systems. Systems ecologists realise that the function of any ecosystem can be influenced by human economics in fundamental ways. They have therefore taken an additional transdisciplinary step by including economics in the consideration of ecological-economic systems. In the words of R.L. Kitching : As
146-579: A physical system under repeated conditions, and it implies that there is a causal relationship involving the elements of the system. Factual and well-confirmed statements like "Mercury is liquid at standard temperature and pressure" are considered too specific to qualify as scientific laws. A central problem in the philosophy of science , going back to David Hume , is that of distinguishing causal relationships (such as those implied by laws) from principles that arise due to constant conjunction . Laws differ from scientific theories in that they do not posit
219-459: A classical problem for the philosophy of language concerning how words convey meaning, there is debate over its validity mostly from two angles of criticism: opposition to compositionality and, especially, instability of meaning. The first claims that meaning holism conflicts with the compositionality of language. Meaning in some languages is compositional in that meaning comes from the structure of an expression's parts. Meaning holism suggests that
292-474: A consistent meaning to the word, Smuts used holism to represent at least three features of reality. First, holism claims that every scientifically measurable thing, either physical or psychological, does possess a nature as a whole beyond its parts. His examples include atoms , cells , or an individual's personality . Smuts discussed this sense of holism in his claim that an individual's body and mind are not completely separated but instead connect and represent
365-404: A highly integrated and ethical fashion" Ecological economics is a transdisciplinary field of academic research that addresses the dynamic and spatial interdependence between human economies and natural ecosystems . Ecological economics brings together and connects different disciplines, within the natural and social sciences but especially between these broad areas. As the name suggests, the field
438-444: A holistic view of the universe explains its processes and their evolution more effectively than a reductive view. Professional philosophers of science and linguistics did not consider Holism and Evolution seriously upon its initial publication in 1926 and the work has received criticism for a lack of theoretical coherence. Some biological scientists, however, did offer favorable assessments shortly after its first print. Over time,
511-420: A law or theory from facts. Calling a law a fact is ambiguous , an overstatement , or an equivocation . The nature of scientific laws has been much discussed in philosophy , but in essence scientific laws are simply empirical conclusions reached by scientific method; they are intended to be neither laden with ontological commitments nor statements of logical absolutes . A scientific law always applies to
584-476: A mechanism or explanation of phenomena: they are merely distillations of the results of repeated observation. As such, the applicability of a law is limited to circumstances resembling those already observed, and the law may be found to be false when extrapolated. Ohm's law only applies to linear networks; Newton's law of universal gravitation only applies in weak gravitational fields; the early laws of aerodynamics , such as Bernoulli's principle , do not apply in
657-428: A mode of scientific enquiry, a central feature of Systems Ecology is the general application of the principles of energetics to all systems at any scale. Perhaps the most notable proponent of this view was Howard T. Odum - sometimes considered the father of ecosystems ecology. In this approach the principles of energetics constitute ecosystem principles . Reasoning by formal analogy from one system to another enables
730-426: A particular phenomenon always occurs if certain conditions be present". The production of a summary description of our environment in the form of such laws is a fundamental aim of science . Several general properties of scientific laws, particularly when referring to laws in physics , have been identified. Scientific laws are: The term "scientific law" is traditionally associated with the natural sciences , though

#1733093828555876-403: A series of improving and more precise generalizations. Scientific laws are typically conclusions based on repeated scientific experiments and observations over many years and which have become accepted universally within the scientific community . A scientific law is " inferred from particular facts, applicable to a defined group or class of phenomena , and expressible by the statement that
949-583: Is biological organization which models biological systems and structures only in terms of their component parts. "The reductionist approach has successfully identified most of the components and many of the interactions but, unfortunately, offers no convincing concepts or methods to understand how system properties emerge...the pluralism of causes and effects in biological networks is better addressed by observing, through quantitative measures, multiple components simultaneously and by rigorous data integration with mathematical models." The objective in systems biology
1022-418: Is a combination of extensive evidence of something not occurring, combined with an underlying theory , very successful in making predictions, whose assumptions lead logically to the conclusion that something is impossible. While an impossibility assertion in natural science can never be absolutely proved, it could be refuted by the observation of a single counterexample . Such a counterexample would require that
1095-463: Is a consequence of the shift symmetry of time (no moment of time is different from any other), while conservation of momentum is a consequence of the symmetry (homogeneity) of space (no place in space is special, or different from any other). The indistinguishability of all particles of each fundamental type (say, electrons, or photons) results in the Dirac and Bose quantum statistics which in turn result in
1168-481: Is also sometimes used in the context of various lifestyle practices, such as dieting , education, and healthcare, to refer to ways of life that either supplement or replace conventional practices. In these contexts, holism is not necessarily a rigorous or well-defined methodology for obtaining a particular lifestyle outcome. It is sometimes simply an adjective to describe practices which account for factors that standard forms of these practices may discount, especially in
1241-440: Is complex. Much of systems ecology can be considered a subset of ecosystem ecology. Ecosystem ecology also utilizes methods that have little to do with the holistic approach of systems ecology. However, systems ecology more actively considers external influences such as economics that usually fall outside the bounds of ecosystem ecology. Whereas ecosystem ecology can be defined as the scientific study of ecosystems, systems ecology
1314-400: Is considered to broadly present insight into the ontological problem. In one sense, holism for physics is a perspective about the best way to understand the nature of a physical system. In this sense, holism is the methodological claim that systems are accurately understood according to their properties as a whole. A methodological reductionist in physics might seek to explain, for example,
1387-418: Is generally understood that they implicitly reflect, though they do not explicitly assert, causal relationships fundamental to reality, and are discovered rather than invented. Scientific laws summarize the results of experiments or observations, usually within a certain range of application. In general, the accuracy of a law does not change when a new theory of the relevant phenomenon is worked out, but rather
1460-456: Is independent and so there are no emergent properties within a language. Additionally, there is meaning molecularism which states that a change in one word alters the meaning of only a relatively small set of other words. The linguistic perspective of meaning holism is traced back to Quine but was subsequently formalized by analytic philosophers Michael Dummett , Jerry Fodor , and Ernest Lepore . While this holistic approach attempts to resolve
1533-411: Is made up of researchers with a background in economics and ecology . An important motivation for the emergence of ecological economics has been criticism on the assumptions and approaches of traditional (mainstream) environmental and resource economics . Ecological energetics is the quantitative study of the flow of energy through ecological systems. It aims to uncover the principles which describe

Their efforts were motivated by a need they perceived for the development of an " ecological self ", which views the human ego as an integrated part of a living system that encompasses
1679-472: Is more of a particular approach to the study of ecological systems and phenomena that interact with these systems. Industrial ecology is the study of industrial processes as linear (open loop) systems, in which resource and capital investments move through the system to become waste, to a closed loop system where wastes become inputs for new processes. Holism Holism is the interdisciplinary idea that systems possess properties as wholes apart from
1752-411: Is not necessarily specified in meaning holism, but typically such a change is taken straightforwardly to affect the meaning of every word in the language. In scientific disciplines, reductionism is the opposing viewpoint to holism. But in the context of linguistics or the philosophy of language , reductionism is typically referred to as atomism. Specifically, atomism states that each word's meaning
1825-425: Is often placed in opposition to reductionism , a dominant notion in the philosophy of science that systems containing parts contain no unique properties beyond those parts. Proponents of holism consider the search for emergent properties within systems to be demonstrative of their perspective. The term "holism" was coined by Jan Smuts (1870–1950) in his 1926 book Holism and Evolution . While he never assigned
1898-505: Is one of the main goals of science. The fact that laws have never been observed to be violated does not preclude testing them at increased accuracy or in new kinds of conditions to confirm whether they continue to hold, or whether they break, and what can be discovered in the process. It is always possible for laws to be invalidated or proven to have limitations, by repeatable experimental evidence, should any be observed. Well-established laws have indeed been invalidated in some special cases, but
1971-425: Is the mathematical consequence of the 3-dimensionality of space . One strategy in the search for the most fundamental laws of nature is to search for the most general mathematical symmetry group that can be applied to the fundamental interactions. Conservation laws are fundamental laws that follow from the homogeneity of space, time and phase , in other words symmetry . Conservation laws can be expressed using
2044-474: Is to advance models of the interactions in a system. Holistic approaches to modelling have involved cellular modelling strategies, genomic interaction analysis, and phenotype prediction. Systems medicine is a practical approach to systems biology and accepts its holistic assumptions. Systems medicine takes the systems of the human body as made up of a complete whole and uses this as a starting point in its research and, ultimately, treatment. The term holism

2336-950: The law of conservation of energy can be written as Δ E = 0 {\displaystyle \Delta E=0} , where E {\displaystyle E} is the total amount of energy in the universe. Similarly, the first law of thermodynamics can be written as d U = δ Q − δ W {\displaystyle \mathrm {d} U=\delta Q-\delta W\,} , and Newton's second law can be written as F = d p d t . {\displaystyle \textstyle F={\frac {dp}{dt}}.} While these scientific laws explain what our senses perceive, they are still empirical (acquired by observation or scientific experiment) and so are not like mathematical theorems which can be proved purely by mathematics. Like theories and hypotheses, laws make predictions; specifically, they predict that new observations will conform to
2409-453: The social sciences also contain laws. For example, Zipf's law is a law in the social sciences which is based on mathematical statistics . In these cases, laws may describe general trends or expected behaviors rather than being absolutes. In natural science, impossibility assertions come to be widely accepted as overwhelmingly probable rather than considered proved to the point of being unchallengeable. The basis for this strong acceptance
2482-469: The (more famous) mass–energy equivalence E = mc is a special case. General relativity is governed by the Einstein field equations , which describe the curvature of space-time due to mass–energy equivalent to the gravitational field. Solving the equation for the geometry of space warped due to the mass distribution gives the metric tensor . Using the geodesic equation, the motion of masses falling along
2555-533: The 2nd, zero resultant acceleration): where p = momentum of body, F ij = force on body i by body j , F ji = force on body j by body i . For a dynamical system the two equations (effectively) combine into one: in which F E = resultant external force (due to any agent not part of system). Body i does not exert a force on itself. From the above, any equation of motion in classical mechanics can be derived. Equations describing fluid flow in various situations can be derived, using
2628-490: The Galilean transformations for low velocities much less than the speed of light c . The magnitudes of 4-vectors are invariants – not "conserved", but the same for all inertial frames (i.e. every observer in an inertial frame will agree on the same value), in particular if A is the four-momentum , the magnitude can derive the famous invariant equation for mass–energy and momentum conservation (see invariant mass ): in which
2701-474: The Lagrangian, is required (in other words it is not as simple as "differentiating a function and setting it to zero, then solving the equations to find the points of maxima and minima etc", rather this idea is applied to the entire "shape" of the function, see calculus of variations for more details on this procedure). Notice L is not the total energy E of the system due to the difference, rather than
2774-571: The Lorentz transformation). Similarly, the Newtonian gravitation law is a low-mass approximation of general relativity, and Coulomb's law is an approximation to quantum electrodynamics at large distances (compared to the range of weak interactions). In such cases it is common to use the simpler, approximate versions of the laws, instead of the more accurate general laws. Laws are constantly being tested experimentally to increasing degrees of precision, which

Some of the more famous laws of nature are found in Isaac Newton 's theories of (now) classical mechanics , presented in his Philosophiae Naturalis Principia Mathematica , and in Albert Einstein 's theory of relativity .

A methodological holist, on the other hand, believes there is something misguided about this approach; one proponent, a condensed matter physicist, puts it: “the most important advances in this area come about by the emergence of qualitatively new concepts at the intermediate or macroscopic levels—concepts which, one hopes, will be compatible with one's information about
3139-438: The behavior of individual parts represents the whole. However, the state of a system in quantum theory resists a certain kind of reductive analysis. For example, two spatially separated quantum systems are described as " entangled ," or nonseparable from each other, when a meaningful analysis of one system is indistinguishable from that of the other. There are different conceptions of nonseparability in physics and its exploration

Many laws take mathematical forms, and thus can be stated as an equation; for example,

The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science ( physics , chemistry , astronomy , geoscience , biology ).

Ecosystem ecology is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals . Ecosystem ecology examines physical and biological structure and examines how these ecosystem characteristics interact. The relationship between systems ecology and ecosystem ecology
3650-400: The general continuity equation (for a conserved quantity) can be written in differential form as: where ρ is some quantity per unit volume, J is the flux of that quantity (change in quantity per unit time per unit area). Intuitively, the divergence (denoted ∇⋅) of a vector field is a measure of flux diverging radially outwards from a point, so the negative is the amount piling up at

It entails a wide range of subject areas including anthropology, engineering, environmental science , ethics and philosophy. At its core, ESEM looks to "rationally design and manage coupled human-natural systems in
3942-462: The instability of meaning holism is an acceptable feature from several different angles. In one example, contextual holists make this point simply by suggesting we often do not actually share identical inferential assumptions but instead rely on context to counter differences of inference and support communication. Scientific applications of holism within biology are referred to as systems biology . The opposing analytical approach of systems biology
4015-409: The meaning of individual words depends on the meaning of other words, forming a large web of interconnections. In general, meaning holism states that the properties which determine the meaning of a word are connected such that if the meaning of one word changes, the meaning of every other word in the web changes as well. The set of words that alter in meaning due to a change in the meaning of some other
4088-467: The meaning of other words, then in order to communicate a message, the sender and the receiver must share an identical set of inferential assumptions or beliefs. If these beliefs were different, meaning may be lost. Many types of communication would be directly affected by the principles of meaning holism such as informative communication, language learning, and communication about psychological states. Nevertheless, some meaning holists maintain that
4161-497: The meaning of the word holism became most closely associated with Smuts' first conception of the term, yet without any metaphysical commitments to monism , dualism , or similar concepts which can be inferred from his work. The advent of holism in the 20th century coincided with the gradual development of quantum mechanics . Holism in physics is the nonseparability of physical systems from their parts, especially quantum phenomena. Classical physics cannot be regarded as holistic, as
4234-544: The meaning of words plays an inferential role in the meaning of other words: "pet fish" might infer a meaning of "less than 3 ounces." Since holistic views of meaning assume meaning depends on which words are used and how those words infer meaning onto other words, rather than how they are structured, meaning holism stands in conflict with compositionalism and leaves statements with potentially ambiguous meanings. The second criticism claims that meaning holism makes meaning in language unstable. If some words must be used to infer

In another sense, holism is a metaphysical claim that the nature of a system is not determined by the properties of its component parts. There are three varieties of this sense of physical holism. The metaphysical claim does not assert that physical systems involve abstract properties beyond
4380-402: The most evolutionarily advantageous system function occurs when the environmental load matches the internal resistance of the system. The further the environmental load is from matching the internal resistance, the further the system is away from its sustainable steady state. Therefore, the systems ecologist engages in a task of resistance and impedance matching in ecological engineering , just as

That is, the invalidated laws have been found to be only close approximations, to which other terms or factors must be added to cover previously unaccounted-for conditions, e.g. very large or very small scales of time or space, enormous speeds or masses, etc. Thus, rather than unchanging knowledge, physical laws are better viewed as

The kinetic energy of the system is T (a function of the rate of change of the configuration of the system), and potential energy is V (a function of the configuration and its rate of change). The configuration of a system which has N degrees of freedom is defined by generalized coordinates q = ( q 1 , q 2 , ... q N ). There are generalized momenta conjugate to these coordinates, p = ( p 1 , p 2 , ..., p N ), where: The action and Lagrangian both contain

Some laws reflect mathematical symmetries found in nature (e.g. the Pauli exclusion principle reflects identity of electrons, conservation laws reflect homogeneity of space , time, and Lorentz transformations reflect rotational symmetry of spacetime ). Many fundamental physical laws are mathematical consequences of various symmetries of space, time, or other aspects of nature. Specifically, Noether's theorem connects some conservation laws to certain symmetries. For example, conservation of energy

In systems ecology the principles of ecosystem energy flows or "ecosystem laws" (i.e. principles of ecological energetics) are considered formally analogous to the principles of energetics. Ecological humanities aims to bridge the divides between the sciences and the humanities, and between Western , Eastern and Indigenous ways of knowing nature. Like ecocentric political theory,
4891-509: The properties of their component parts. The aphorism "The whole is greater than the sum of its parts", typically attributed to Aristotle , is often given as a glib summary of this proposal. The concept of holism can inform the methodology for a broad array of scientific fields and lifestyle practices. When applications of holism are said to reveal properties of a whole system beyond those of its parts, these qualities are referred to as emergent properties of that system. Holism in all contexts
4964-1138: The properties of those particles guiding their trajectories. Bohm's ontological holism concerning the nature of whole physical systems was literal. But Niels Bohr (1885-1962), on the other hand, held ontological holism from an epistemological angle, rather than a literal one. Bohr saw an observational apparatus to be a part of a system under observation, besides the basic physical parts themselves. His theory agrees with Bohm that whole systems were not merely composed of their parts and it identifies properties such as position and momentum as those of whole systems beyond those of its components. But Bohr states that these holistic properties are only meaningful in experimental contexts when physical systems are under observation and that these systems, when not under observation, cannot be said to have meaningful properties, even if these properties took place outside our observation. While Bohr claims these holistic properties exist only insofar as they can be observed, Bohm took his ontological holism one step further by claiming these properties must exist regardless . Semantic holism suggests that

As with other kinds of scientific knowledge, scientific laws do not express absolute certainty, as mathematical laws do.

5256-546: The universe. Smuts perceived evolution as the process of nature correcting itself creatively and intentionally. In this way, holism is described as the tendency of a whole system to creatively respond to environmental stressors, a process in which parts naturally work together to bring the whole into more advanced states. Smuts used Pavlovian studies to argue that the inheritance of behavioral changes supports his idea of creative evolution as opposed to purely accidental development in nature. Smuts believed that this creative process
5329-399: Was intrinsic within all physical systems of parts and ruled out indirect, transcendent forces . Finally, Smuts used holism to explain the concrete (nontranscendent) nature of the universe in general. In his words, holism is "the ultimate synthetic, ordering, organizing, regulative activity in the universe which accounts for all the structural groupings and syntheses in it." Smuts argued that
