Cybernetic systems are systems with feedback (Wiener 1948). They are a special class of cause-and-effect (input-output) systems in which input is determined, at least in part, by output. The portion of output that is returned to input is the feedback, and this may become the basis for feedback control. Very small feedbacks may exert very large effects. Figure la illustrates a basic input-output system. Energy, matter, or information coming from the environment causes the system to respond; this… Expand
Adding artificial feedback to a simple aquatic ecosystem: the cybernetic nature of ecosystems revisited
TLDR
The experimental addition of new feedback is apparently a useful means of investigating the self-organizational properties of ecosystems and may also improve the understanding of the consequences of anthropogenically induced feedback in natural and managed systems. Expand
Towards a control model for the highly cybernetic farming ecosystems

TLDR
It is demonstrated using input‐output analysis technique that residuals generated in the farming system is the most important cybernetic variable, so that the proper management of residuals alone has the potential to maintain future productivity and sustainability. Expand
Natural ecosystem design and control imperatives for sustainable ecosystem services
TLDR
The conclusion from these results is that ecosystems under natural conditions evidence organizational properties evolved over evolutionary time, and management for sustainable extraction of ecosystem services should seek to preserve and emulate these properties in the new exploited states. Expand
Engineering of highly autonomous biosystems: Review of the relevant literature
TLDR
The EcoCyborg Project, in which computer models are used to investigate the engineering of ecosystems combined with artificially intelligent control networks, exists at the nexus of several expansive fields of research, and the review therefore is not comprehensive. Expand
Ecosystems emerging:: 4. growth
Abstract This fifth paper in the series on Ecosystems Emerging treats the properties of ecosystem growth and development from the perspective of open (paper four), nonequilibrium, thermodynamicExpand
Regulation/Adaptation: Control Aspects of Ecological Systems
TLDR
This chapter addresses regulation/adaptation, one of the core ecological system functions, in detail, and the interaction outcomes strongly suggest and support the prevalence of fluctuating dynamics in ecosystems. Expand

Abstract Feedback loops stabilize energy and nutrient flow in ecological food webs and the ecosystems in which they are embedded. In these feedback loops, flow of energy propels nutrients fromExpand
Darwinian Evolution in Ecosystems: A Survey of Some Ideas and Difficulties Together with Some Possible Solutions
Ecology, the biological science of environment, has not produced a synthesis of environment from its broad technical knowledge of influence of external parameters on organisms. Before Darwin (1859),Expand
Ecosystem spatial self-organization: Free order for nothing?
TLDR
This work explores whether spatial self-organization provides a mechanism for such feedback for ecosystems as CAS, that is, whether ecosystem-level outcomes of self-organized patterning could feed back to affect or even reinforce local pattern-forming processes at the agent level. Expand
Network perspectives on ecological indicators and actuators: Enfolding, observability, and controllability
TLDR
Network enfolding is a powerful expression of systemic holism and the source of what is termed the “indicator problem”, and formal theory can help structure the indicator problem and its relationship to management. Expand

System Theory of the Ecological Niche
TLDR
To illustrate the span of the new system theory of the niche and its extension to environs, adaptation, succession, competitive exclusion, coevolution, niche (and environ) overlap, output niche, and dominance and control are each discussed within the new framework. Expand
Environs: Relativistic Elementary Particles for Ecology
TLDR
It is suggested that ecology lacks an elementary particle of its own, with discoverable properties that can clarify the nature of environment and its relationship to life, and what is known about it and some directions for learning more. Expand
The Noncybernetic Nature of Ecosystems
Ecosystems lack (1) global information networks to integrate their parts, (2) low-energy cause and high-energy effect interactions to make the regulation of high-energy events possible, and (3)Expand

The hypothesis that complexity and stability are positively correlated was experimentally tested at the ecosystem level of organization using intact terrestrial microcosms. Power spectral densitiesExpand
Ecosystem Persistence and Heterotrophic Regulation
TLDR
Mechanisms leading to ecosystem persistence are explored with a simple mathe- matical conceptualization and it is suggested that simple mathematical constructs, quantifiable from available data and amenable to direct analysis, have much to offer in increasing understanding of ecosystem function.
