The skylight gradient of luminance helps sandhoppers in sun and moon identification.
To return to the ecologically optimal zone of the beach, the sandhopper Talitrus saltator (Montagu) maintains a constant sea-land direction based on the sun and moon compasses. In this study, we investigated the role of the skylight gradient of luminance in sun and moon identification under natural and artificial conditions of illumination. Clock-shifted (inverted) sandhoppers tested under the ...
متن کاملActivity rhythms and orientation in sandhoppers (Crustacea, Amphipoda).
The aim of the present review is to combine knowledge of locomotor activity rhythms with that of compass orientation in littoral arthropods. Talitrid amphipods (the sandhoppers) represent a good biological model in the fields of animal orientation and biological rhythms. The paper examines the activity rhythms of different species of sandhoppers (mainly Talitrus saltator), as well as the chrono...
متن کاملStromatolites and Earth--sun--moon Dynamics
Vanyo, J.P. and Awramik, S.M., 1985. Stromatolites and Earth--Sun--Moon dynamics. Precambrian Res., 29 : 121--142. Inclination of stromatolite columns, caused by nonvertical direction of averaged incident solar radiation, provides a signal for deducing astronomical and geophysical data at time of stromatolite formation. A sample of Anabaria juvensis (Bitter Springs Formation, central Australia)...
متن کاملThe Wives of the Sun and Moon
In much Native American mythology, marriage is conceptualized as a monthly honeymoon interrupted at each dark moon by menstruation. Woman’s monthly alternation between marital sex and menstrual seclusion is coded as an alternation between her rival partners, Sun and Moon. Against this background, a Plains Indian myth attempts to come to terms with a novel problem. With the introduction of patri...
متن کاملMoon and Sun shadowing effect in the MACRO detector
Using data collected by the MACRO experiment from 1989 to the end of its operations in 2000, we have studied in the underground muon flux the shadowing effects due to both the Moon and the Sun. We have observed the shadow cast by the Moon at its apparent position with a significance of 6.5 σ. The Moon shadowing effect has been used to verify the pointing capability of the detector and to determ...
