BIO-8 Lecture Notes - Lecture 5: Environmental Factor, Sequential Analysis
Document Summary
That is what is the reason for absence of a species from a given area. To answer this, set up a transplant experiment. Handle individuals identically to treatment group, but : Place them back into their native site. Handle individuals identically to control group, but. Variable studied is location (only thing that"s different) Answer is yes: if experiments show that location is suitable (both groups have same rates); shows its habitat choice and dispersal. Answer is no: shows this habitat is unsuitable. Non-native"s site conditions or resources or both. Limitation by biotic factors or physical or chemical selection aren"t suitable factors. Shelford"s law of tolerance: factor that organism is most sensitive to controls. Distribution controlled by environmental factor for which the organism distribution has the narrowest range of physiological adaptability. Several factors may interact to set distributional limits. Acclimation: physiological process where organisms become adjusted to specific set of ecological factors.
