Phytosemiotics is a branch of biosemiotics that studies the sign processing capabilities present in plants. [1] Some functions that plants perform that utilize this simple semiosis includes cellular recognition, plant perception, intercellular communication, [1] and plant signal transduction. [2] Comparative to the sign processing present in animals and humans, phytosemiotics occurs at the cellular level, with communication between the cells of plants acting as a means of observing their surroundings and making rudimentary decisions. [1]
The addition of phytosemiotics into the broader scale of semiotic research remains a controversial one, as determining the extent to which plants actually exhibit sign processing remains a debate, as the range of what signs are able to be processed by plants remains fairly limited compared to the semiotic capabilities of humans or animals. [2] If fully recognized, phytosemiotics could expand semiotic research beyond a focus on human or animal semiotics into the other kingdoms of life, including fungi and bacteria. [1] It could also change how we view the components that make up effective sign processing and how non-human/animal life is capable of more advanced sign processing. [2]
The term 'phytosemiotics' was introduced by German psychologist and semiotician Martin Krampen, in 1981. After participating in an experiment involving a subject living in a plant-filled greenhouse, Krampen became interested in the semiotic processing capabilities of plants. After consulting with the works of Jakob von Uexküll, in particular his 'Theory of Meaning', Krampen further developed this concept and eventually wrote "Phytosemiotics", the first essay covering the topic. [3]
Despite the fundamentally different biological systems that make up animals and plants, there are comparisons to be made in the ways they undergo semiotics. One possible similarity is the presence of vegetative semiotics within plants as well as animals, as intercellular communication is an important aspect of all life. [1] Another example is the ability to distinguish which aspects in the immediate environment of a creature (also known as their 'umwelt') are important to their survival and which ones are not. [3] While plants do not have an umwelt in the traditional sense, they are able to deduce what surrounding resources are important to them and which ones are not. [3]
An important aspect of phytosemiotics is understanding how plants undergo semiosis differently than how animals experience it. [3] One important difference is the lack of 'receptor' and 'effector' organs in plants, unlike animals who are able to see their environment and interact with it in a more direct way than plants are able to. [3] While plants may not have tradition receptor or effector organs in the same way animals do, plants do use signal transduction to send external signals throughout the plant to make simple decisions. [2] Another important difference is the types of signs plants are able to process. While plants can only process indexes, animals can also process icons and humans can further process symbols. [3]
Semiotics is the systematic study of sign processes and the communication of meaning. In semiotics, a sign is defined as anything that communicates intentional and unintentional meaning or feelings to the sign's interpreter.
Semiosis, or sign process, is any form of activity, conduct, or process that involves signs, including the production of meaning. A sign is anything that communicates a meaning, that is not the sign itself, to the interpreter of the sign. The meaning can be intentional such as a word uttered with a specific meaning, or unintentional, such as a symptom being a sign of a particular medical condition. Signs can communicate through any of the senses, visual, auditory, tactile, olfactory, or taste.
Biosemiotics is a field of semiotics and biology that studies the prelinguistic meaning-making, biological interpretation processes, production of signs and codes and communication processes in the biological realm.
Zoosemiotics is the semiotic study of the use of signs among animals, more precisely the study of semiosis among animals, i.e. the study of how something comes to function as a sign to some animal. It is the study of animal forms of knowing.
Jakob Johann Freiherr von Uexküll was a Baltic German biologist who worked in the fields of muscular physiology and animal behaviour studies and was an influence on the cybernetics of life. However, his most notable contribution is the notion of Umwelt, used by semiotician Thomas Sebeok and philosopher Martin Heidegger. His works established biosemiotics as a field of research.
An umwelt is the specific way organisms of a particular species experience the world, which is dependant on what their sensory organs and perceptual systems can detect and interpret.
Thomas Albert Sebeok was a Hungarian-born American polymath, semiotician, and linguist. As one of the founders of the biosemiotics field, he studied non-human and cross-species signaling and communication. He is also known for his work in the development of long-term nuclear waste warning messages, in which he worked with the Human Interference Task Force to create methods for keeping the inhabitants of Earth away from buried nuclear waste that will still be hazardous 10,000 or more years in the future.
The semiosphere is a concept in biosemiotic theory, according to which - contrary to ideas of nature determining sense and experience - the phenomenal world is a creative and logical structure of processes of semiosis where signs operate together to produce sense and experience.
Kalevi Kull is a biosemiotics professor at the University of Tartu, Estonia.
John Deely was an American philosopher and semiotician. He was a professor of philosophy at Saint Vincent College and Seminary in Latrobe, Pennsylvania. Prior to this, he held the Rudman Chair of Graduate Philosophy at the Center for Thomistic Studies, located at the University of St. Thomas (Houston).
Karl Kuno Thure Freiherr von Uexküll was a German scholar of psychosomatic medicine and biosemiotics. He developed the approach of his father, Jakob von Uexküll, in the study of living systems and applied it in medicine.
Martin Krampen was a leading German semiotician, semiotics Professor in Göttingen.
Giorgio Prodi was an Italian medical scientist, oncologist and semiotician.
Jesper Hoffmeyer was a professor at the University of Copenhagen Institute of Biology, and a leading figure in the emerging field of biosemiotics. He was the president of the International Society for Biosemiotic Studies (ISBS) from 2005 to 2015, co-editor of the journal Biosemiotics and the Springer Book series in Biosemiotics. He authored the books Biosemiotics: An Examination into the Signs of Life and the Life of Signs and Signs of Meaning in the Universe and edited A Legacy for Living Systems: Gregory Bateson as Precursor to Biosemiotics.
Ecosemiotics is a branch of semiotics in its intersection with human ecology, ecological anthropology and ecocriticism. It studies sign processes in culture, which relate to other living beings, communities, and landscapes. Ecosemiotics also deals with sign-mediated aspects of ecosystems.
The following outline is provided as an overview of and topical guide to semiotics:
Semiotics of culture is a research field within semiotics that attempts to define culture from semiotic perspective and as a type of human symbolic activity, creation of signs and a way of giving meaning to everything around. Therefore, here culture is understood as a system of symbols or meaningful signs. Because the main sign system is the linguistic system, the field is usually referred to as semiotics of culture and language. Under this field of study symbols are analyzed and categorized in certain class within the hierarchal system. With postmodernity, metanarratives are no longer as pervasive and thus categorizing these symbols in this postmodern age is more difficult and rather critical.
Susan Petrilli is an Italian semiotician, professor of philosophy and theory of languages at the University of Bari, Aldo Moro, Italy, and the seventh Thomas A. Sebeok Fellow of the Semiotic Society of America. She is also International Visiting Research Fellow at the School of Psychology, the University of Adelaide, South Australia.
Paul Cobley is an eminent British semiotician and narratologist.
Neurosemiotics is an area of science which studies the neural aspects of meaning making. It interconnects neurobiology, biosemiotics and cognitive semiotics. Neurolinguistics, neuropsychology and neurosemantics can be seen as parts of neurosemiotics.
