Perspectivas de biosemiotica en casos biológicos

Resumen

This book, like the first volume, is basically a collection of papers with the principal aim of offering the practical applications of the theory presented in volume 1. In consequence, this review will be, also, intends chapter by chapter. The first chapter intend to show communication in plants under the biosemiotic paradigm, which involves sign processes that are realized among plants of different species, plants with other organisms, and also among cells, and, even, in cells of the same plant. To that aim the author provides interesting examples in each kind of interaction. What is worth to note is the proposition that chemical molecules function as signs and that they are interpreted which implies that they are differing from molecules that not form part of messages, which are noise. In connection to this it should be noted the sense of the term semiochemicals that the author specifies, he points out that it must embrace all chemicals which are involved as signs, in sign-mediated interactions in and between organisms. Which is also interesting is the similarity between plants and animals in the developing of immune substances and even more the synapse-like communication among all parts of the plant and recognition in neuronal-like networks, that are a possible explanation of some kind of memory shown by plants, all this could be part of an underlying principle that could be called the relativity constancy of patterns. What seems something misleading is the assertion that plants have a decentralized nervous system which seems not proved.
