Heliotropic Animals as Photometers on the Basis of the Validity of the Bunsen-Roscoe Law for Heliotropic Reactions.
While it was customary to express animal instincts in terms of human behavior, one of us many years ago began to replace this anthropomorphic. method by the objective and quantitative methods of the physicist. These methods were most easily applicable in the case of those instincts familiar to every layman in which animals were apparently attracted or repelled by light. Loeb1 was able to expres...
متن کاملLight and the Muscle Tonus of Insects the Heliotropic Mechanism
The tonus of the muscles of heliotropic insects is due chiefly to the action of light; it is markedly decreased in the dark. Each eye controls the tonus of a different group of muscles on both sides of the body. Different areas of each eye likewise are related to the tonus of different muscle groups, and the relationship is entirely analogous to that of the otic labyrinth of vertebrates. Asymme...
متن کاملHeliotropic leaf movements in common beans controlled by air temperature.
Heliotropic leaf movements were examined in common beans (Phaseolus vulgaris cv Blue Lake Bush) under outdoor and laboratory conditions. Heliotropic leaf movements in well-watered plants were partly controlled by temperature, and appeared to be independent of atmospheric humidity and CO(2) concentration. When environmental conditions were held constant in the laboratory, increased air temperatu...
متن کاملTranscriptome of the freshwater amphipod Gammarus pulex hepatopancreas
So far, ecotoxicological studies used biomarkers of exposure or of effects in order to investigate the impacts of contaminated areas on biota (Peakall, 1994 [6]). However, although these results are important in the ecotoxicological risk assessment, biomarkers are very specific and only provide information on the biological processes or physiological pathways targeted by the biomarkers experime...
متن کاملAn Investigation into Formal Animals
1 Preface Animals walk the earth, y through the air and occupy the ocean deeps in countless millions. Their nervous systems receive information about the external world, and also about the state of their own bodies, process it and generate responses, commonly complex sequences of muscle contractions. A description of this process at the physical level of, for example, photons impinging on the r...
