Understanding behavioral changes of prey and predators based on lunar illumination provides insight into important life history, behavioral ecology, and survival information. The objectives of this research were to determine if bobcat movement rates differed by period of day (dark, moon, crepuscular, day), lunar illumination (<10%, 10 - <50%, 50 - <90%, >90%), and moon phase (new, full). Bobcat...
In this study, we examined the effect of weather and moon illumination on sand fly activity, as measured by light trap collections made between 2 May 2003 and 25 October 2004 at Tallil Air Base, Iraq. Wind speed, temperature, dew point, percentage of sky cover, and moon illumination were entered into principal components analysis. The resulting principal components were entered into stepwise re...
A surprisingly large amount of information on our solar system can be gained from simple measurements of the apparent angular diameters of the sun and the moon. This information includes the average density of the sun, the distance between earth and moon, the radius of the moon, and the gravitational constant. In this note it is described how these and other quantities can be obtained by simple...
Introduction: The irregular shape of the Moon may be explained in detail by assuming that a single large impact struck the near side of the Moon and deposited its ejecta on the far side [4], [5], [8], [9]. The impactor would have been very large in order to deposit the 5 kilometer bulge on the far side, perhaps 300 to 600 kilometers in diameter, and the internal basin would have covered more th...
