Ecosemiotics represents a theoretical approach to human ecology that can be applied across several disciplines. lts primary justification lies inthe ambition to transcend "Cartesian", conceptual dichotomies such as culture/nature. society/nature, mental/material. etc. It argues that ecosystems areconstituted no less by flows of signs than by flows of matter and energy. This paper discusses the roles of different kinds of hmnan sign systems in the ecologyof Amazonia, ranging from the phenomenology of unconscious sensations. through linguistic signs such as metaphors and ethnobiological taxonomies, to money and the political economy of environmental destruction. Human-environmental relations mediated by direct, sensory and (oral) linguistic communication have tended to enhance biological diversity, suggesting modes of calibrating the long-term co-evolution of human and non-human populations. Economic sign systems, on the other hand, have rapidly and drastically transfonned human-environmental relations in Amazonia to the point where the entire rainforest ecosystem is illlder threat. In detaching themselves from the direct, "face-to-face" communication between humans and their natural environments, flows of money and commodities - and the decontextualized knowledge systems that they engender - have no means of staying geared to the long-term negotiation of local, ecological co-existence. It is argued that the ongoing deterioration of the biosphere can be viewed as a problem of communication, deserving semiotic analysis.

The emerging epistemic community of ecosemioticians and the multidisciplinary field of inquiry known as ecosemiotics offer a radical and relevant approach to so-called global environmental crisis. There are no environmental fixes within the dominant code, since that code overdetermines the future, thereby perpetuating ecologically untenable cultural forms. The possibility of a sustainability transition (the attempt to overcome destitution and avoid ecocatastrophe) becomes real when mediated by and through ecosemiotics. In short, reflexive awareness of humankind's linguisticality is a necessary condition for transforming ecologically maladaptive cultural forms. As a multidisciplinary, interdisciplinary research program integrating the human and natural sciences, ecosemiotic inquiry closes the gap between biophysical ecology and human ecology. A provisional outline of a pragmatic theory of ecoserniotics attempts to describe the processes by which adaptive cultural changes might be facilitated and points toward substantive content areas that constitute sites for further research. Ecosemiotic inquiry frames cultural codes as these shape and reproduce the ongoing stream of individual and societal choices that shape distinctively human existence in a larger context of biophysical realities that drive natural selection. However, while ecosemiotics is a necessary condition for the sustainability transition, it is not a sufficient condition.

Following Peirce's broad concept of semiosis as a foundation of a field ofsrudy, the semiotics ofphysical nanrre, it is argued that we have to explore the interconnections of Peirce's semiotics with metaphysics. These interconnections will be analyzed in five steps: (I) Peirce's radical antidualism and evolutionism, implied in his synechistic ideas, (2) Peirce's semiotic statement that "all this universe is perfused with signs if it is not composed exclusively of signs" (CP 5.448, n.l), (3) Peirce's bold statement that "matter is effete mind, inveterate habits becoming physical laws" (CP 6.24), (4) his theory of final causation, which can only be properly understood in the light of semiosis, (5) his metaphysics and his methodeutics in relation to semiotics. The laws of nature are discovered by abductive inference revealing an affinity between the human mind and the designs of nature. Hence, the formal laws of thought are not simply laws of our minds but laws of the intelligibility of things.

This article poses the hypothesis that the problem of the intrinsic value of nature that stems from the work of G. E. Moore and is widely discussed in environmental philosophy, bas a parallel in a contemporary discussion in semiotics on the existence of semiosis in nature. From a semiotic point of view. value can be defined as an intentional dimension of sign. This is concordant with a biological interpretation of value that relates to biological needs. Thus. a semiotic approach in biology may provide a useful tool for further analysis of the intrinsic value problem in the biological realm. From an ecosemiotic point of view, the problem is also related to the concepts of bioart and ecoart. Ecoart viz environmental art is that which encompasses the human ambience, e.g., landscape or its components. Bioart call be defined as the art whose material ("clay") is a living body, living matter or communication of organisms (which may include, e.g., genetic engineering). It is concluded that the acceptance of biosemiotic view has implications for a large area of ecological philosophy.

This paper attempts to put forward an aesthetic theory of nature based on a biosemiotic description of the living, which in turn is derived from an autopoietic theory of organism (p. Varela). An autopoietic system's reaction to material constraints is the unfolding of a dimension of meaning. In the outward Gestalt of autopoietic systems, meaning appears as fonn, and as such it reveals itself in a sensually graspable manner. The mode of being of organisms has an irreducible aesthetic side in which this mode of being becomes visible. Nature thus displays a kind of transparency of its own functioning: in a nondiscursive way organisms show traces of their conditio vitae through their material self-presentation. Living beings hence always show a basic level of expressiveness as a necessary component of their organic mode of being. This is called the ecstatic dimension of nature (G. Böhme, R. Corrington). Autopoiesis in its full consequence then amounts to a view reminding of Paracelsus' idea of the signatura rerum (c. Glacken, H. Böhme): nature is transparent, not because it is organized digitally as a linguistic text or code, but rather because it displays analogically the kind of intentionality engendered by autopoiesis. Nature as a whole, as «living fonn" (S. Langer), is a symbol for organic intentionality. The most fundamental meaning of nature protection thus is to guarantee the «real presence" of our soul.

During the recent decades, a global culrural-institutional network has gradually grown lip to project, implement, and use an enormous technological web that is supposed to observe, monitor, communicate, inventory, and assess our environment and its biodiversity in order to implement sustainable management models. The majority of "knowledge tools" that have been incorporated in the mainstream of this "techno-web" are amply based on a combination of mechanistic biology, genetic reductionism, economical determinism and neo-Darwinian cultural and biological perspectives. These approaches leave aside many of the qualitative and relational aspects that can only be grasped by considering the semiotic networks operative in complex ecological and cultural systems. In this paper, it is suggested that a biosemiotic approach to ecology may prove useful for the modelling process which in turn will allow the construction of meaningful monitoring systems. It is aJso advanced that it may as well serve to better integrate our understanding and monitoring of ecosystems into the cultural process of searching for (human) sustainability.

A main question for semiotics today is how far does the paradigm for the action of signs, semiosis. extend. There is general agreement by now that semiosis extends at least as far as awareness or cognition occurs, which includes the entire domain of animal sign usage, or zoosemiosis. The open question today is whether semiotics is broader still, and on this question two positions have emerged. The comparatively conservative position would extend semiotics to the whole of living things. This extension was first formally proposed and argued under the label phytosemiotics, the study of an action of signs in the realm of vegetable life. The conservative faction has rallied around the label of biosemiotics. The more radical faction argues that even this extension leaves something out, namely, the physical universe at large which surrounds and upon which depends all life. The radical argument is that what is distinctive of the action of signs is the shaping of the past on the basis of furore events, a shaping that can be discerned even in the rocks and among the stars - a veritable physiosemiosis, theoretical justification and practical exploration ofwhich marks the final frontier of semiotic inquiry.

Mimicry has been an important topic for biology since the rise of the Darwinian theory of evolution. However. by its very narure mimicry is a sign process and the quest for understanding mimicry in biology has intrinsically always been a semiotic quest. In this paper various theories since Henry W. Bates will be examined to show how the concept of mimicry has been shifted from perceptual resemblance to a particular communicative structure. A concept of mimicry will then be formulated which emphasizes its dynamic properties, and finally, mimicry will be considered in the framework of ecosemiotics.

The article develops a suggestion of how cybersemiotics is pertinent to ecosemiotics. Cybersemiotics uses Luhmann's triadic view of autopoietic systems (biological, psychological, and socio-communicative autopoiesis) and adopts his approach to communication within a biosemiotic framework. The following levels of exosemiosis and signification can be identified under the consideration of nonintentional signs, cybernetics, and information theory: (1) the socio-communicative level of self-conscious signification and language games. (2) the instinctual and species specific level of sign stimuli signifying through innate release response mechanism and sign games, and (3) the level of structural coupling, signal recognition, and languaging, where cybernetic feedback loops evince differences. Signification and communication levels arise whenever autopoietic systems interpenetrate (I) with the language system's semiotic and the psyche's phenosemiotic processes based on imaging, emotion, and volition and (2) between the psyche's phenosemiotic and the body's endosemiotic processes. It is at these two levels that we have the ecosemiotic signification processes of nonintentional signs in nature. Humans are linguistic cyborgs as animals are sign cyborgs because signs at different levels interpenetrate and form our embodied processes. Sign producing and interpreting capability has had selective influence on both animals and humans in evolution.

Ecosemiotics is the study of sign processes (semioses) in relation to the natural environment in which they occur. The paper examines the cultural, biological, and evolutionary dimensions of ecosemioses on the basis of C. S. Peirce's theory of continuity between matter and mind and investigates the ecosemiotic dimensions of natural signs. Ecosemiotics and the semiotics of nature are distinguished from pansemiotism, and the coevolution of sign processes with their natural enviromnent is discussed as a determining factor of ecosemiosis.
