To perceive environmental chemical compounds and to convert these external signals into an intracellular message might be the oldest way for a living being to get information from the outside world. Chemoreceptors are proteins or protein complexes that detect molecules from the outside world either at distance (olfaction) or at close range (gustation). Chemoreceptors can operate as ionotropic or as metabotropic receptors. Ionotropic receptors form ion channels that are activated via ligand binding. Activation of a metabotropic receptor initiates an intracellular signaling cascade that could include a change of enzymatic activity, production of second messenger or activation of ion channels. The receptor performance has to be fine-tuned according to the actual physiological requirements and the presentation of the chemical signal. This Research Topic collects reports and reviews on structure and function of chemoreceptors in the animal kingdom, and how these receptors are regulated.
Insect Taste offers an accessible overview to some of the many advances in insect taste research. The book covers how insects solve the basic problem of taste gustatory processing, from detection and transduction, through coding to the generation of behavior and the evolutionary biology underpinning gustaory learning.
This book compiles the latest information on different kinds of natural, plant-based super sweeteners. A book on alternative, natural super sweeteners is extremely timely and useful, especially, in light of the decreasing cultivable area, ever increasing demand for sucrose, and the well identified ills of sugar consumption. Every year more than 5.0 million people die due to diabetes and diabetes-associated diseases like cardiovascular, kidney disorder, liver cancer etc. This book describes the use of non-saccharide super sweet principles to counter such maladies. The readers will get an in-depth understanding of different kinds of sweeteners, molecular basis of sweetness, their general class...
This Research Topic eBook includes articles from Volume I and II of The Future of Physiology: 2020 and Beyond series: Research Topic “The Future of Physiology: 2020 and Beyond, Volume I” Research Topic “The Future of Physiology: 2020 and Beyond, Volume II” The term Physiology was introduced in the 16th century by Jean Francois Fernel to describe the study of the normal function of the body as opposed to pathology, the study of disease. Over the ensuing centuries, the concept of physiology has evolved and a central tenet that unites all the various sub-disciplines of physiology has emerged: the quest to understand how the various components of an organism from the sub-cellular and cel...
Not since Paul the octopus became famous during the 2010 soccer world cup have scientists realized that decision-making is not a capacity exclusive to the so-called 'higher' animals. Invertebrate animals show an amazing capacity for making decisions even if the external circumstances provide little or no information. This Research Topic celebrates the diversity of decision-making by showcasing the most well-studied cases in a range of invertebrate species.
This book enables the students, researchers and teachers of crop protection faculty to understand and practice the pheromones of the fauna that have been designated by scientists. This compendium of information includes the following topics amongst others: • A timeline detailing the history of the pheromones • Information on the mentors of pheromone research • Types of signalling in various groups of fauna • Modes of communication among fauna and insects • Alarm signals, attractants, recognition signals, indirect guiding Kinesis, orthokinesis, klinokinesis, etc. • Types of communication among conspecifics • Modes of Communication • The broad categories of the pheromones • P...
The reason why insect-plant relationships attract more and more attention has been given by Professor Schoonhoven in the introductory lecture to this symposium: `The green blanket on the earth's surface with its myriads of insects has already revealed some of its complex workings, but contains many more facets which need to be discovered to gratify our insatiable curiosity, as well as help to improve agricultural production'. The 9th International Symposium on Insect-Plant Relationships (SIP-9) was once more, following the tradition established in 1958, a forum for investigators in both basic and applied entomology. Participants from 26 countries throughout the world presented 12 keynote lectures and a total of 141 oral presentations and posters. The proceedings volume contains 72 contributions of both oral lectures and posters which were all peer-reviewed by two independent referees.
Cet ouvrage présente les grandes fonctions des insectes, leur fonctionnement individuel et collectif, leurs interactions plus ou moins intimes avec les composantes de l’écosystème, en particulier les plantes, en s’appuyant sur l’histoire évolutive à l’origine de ces interactions. Il décrit les multiples applications des recherches sur les insectes pour l’agriculture.
Vingt ans après la découverte des récepteurs olfactifs, ce livre fait le point des apports de la biologie moléculaire et de la neurobiologie expérimentale aux sciences du goût et de l’odorat. Il offre un panorama des découvertes récentes sur la réception et le traitement des messages olfactifs et gustatifs et leurs implications biologiques et sociales. Des nez bioélectroniques à la lutte biologique en passant par le comportement des consommateurs et le diagnostic des maladies, les auteurs ont sélectionné quelques applications actuelles et prometteuses.
