Biosemiotics (from the Greek βίος bios, "life" and σημειωτικός sēmeiōtikos, "observant of signs") 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.
To explain the relationship between semiotics and communication studies, communication is defined as the process of transferring data and-or meaning from a source to a receiver. Hence, communication theorists construct models based on codes, media, and contexts to explain the biology , psychology , and mechanics involved.
Inter-organismic communication includes human speech, which is key to maintaining social structures. Dolphins communicate with one another to aid navigation. Dolphins communicate with one another in a number of ways by creating sounds, making physical contact with one another and through the use of body language. Dolphins communicate vocally ...
Cell signaling (or communication) is the ability of cells to receive, process, and transmit signals with its environment and with itself. [ 55 ] [ 56 ] Signals can be non-chemical such as light, electrical impulses , and heat, or chemical signals (or ligands ) that interact with receptors , which can be found embedded in the cell membrane of ...
Plant cells are surrounded by cell walls which are barriers for cell-cell communication. This barrier is overcome by specialized junctions called plasmodesmata. They are similar to gap junctions, connecting the cytosol of adjacent cells. Small molecules (<1000 Da), such as ions, amino acids, and sugars, can diffuse freely through plasmodesmata.
In their 1972 book Autopoiesis and Cognition, Chilean biologists Maturana and Varela described how they invented the word autopoiesis. [4]: 89 : 16 "It was in these circumstances ... in which he analyzed Don Quixote's dilemma of whether to follow the path of arms (praxis, action) or the path of letters (poiesis, creation, production), I understood for the first time the power of the word ...
The communication systems of songbirds is commonly described as a system that is based on syntactic operations. Specifically, bird song enables the systematic combination of sound elements in order to string together a song. Likewise, human languages also operate syntactically through the combination of words, which are calculated systematically.
A biological network is a method of representing systems as complex sets of binary interactions or relations between various biological entities. [1] In general, networks or graphs are used to capture relationships between entities or objects. [1]
