""An Experimental Analysis Of The Relation Between Physiological States And Rheotaxis In Isopoda"" is a scientific research paper published in 1912 by American ecologist and zoologist Warder Clyde Allee. The paper presents the findings of a series of experiments conducted to investigate the relationship between physiological states and rheotaxis (the tendency of an organism to move towards or away from a current) in isopods, a type of crustacean.Allee's experiments involved subjecting isopods to various physiological stressors, such as changes in temperature and oxygen levels, and observing their response to a water current. The results of the experiments showed that the isopods' rheotactic behavior was influenced by their physiological state, with stressed individuals exhibiting a reduced response to the water current.The paper provides a detailed description of the experimental methods used, as well as the results and conclusions drawn from the research. It also includes a discussion of the broader implications of the findings for the study of animal behavior and ecology.Overall, ""An Experimental Analysis Of The Relation Between Physiological States And Rheotaxis In Isopoda"" is a significant contribution to the field of animal behavior and provides valuable insights into the complex relationship between physiology and behavior in organisms.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
