Semilunar Reproductive Cycles in Fundulus Heteroclitus (pisces: Cyprinodontidae) in an Area without Lunar Tidal Cycles
Although lunar spawning rhythms are relatively common in species of shallow-water fish, semilunar reproductive cycles have been reported in a small but growing number of species (Korringa 1947; Johannes 1978). Species with the best documented semilunar gonad and spawning cycles include the California grunion. LeurestMs tenuis, (Clark 1925); Atlantic silversides, Menidia menidia, (Middaugh 1981)...
متن کاملHuman Responses to the Geophysical Daily, Annual and Lunar Cycles
Collectively the daily, seasonal, lunar and tidal geophysical cycles regulate much of the temporal biology of life on Earth. The increasing isolation of human societies from these geophysical cycles, as a result of improved living conditions, high-quality nutrition and 24/7 working practices, have led many to believe that human biology functions independently of them. Yet recent studies have hi...
متن کاملReproductive cycles in tropical intertidal gastropods are timed around tidal amplitude cycles
Reproduction in iteroparous marine organisms is often timed with abiotic cycles and may follow lunar, tidal amplitude, or daily cycles. Among intertidal marine invertebrates, decapods are well known to time larval release to coincide with large amplitude nighttime tides, which minimizes the risk of predation. Such bimonthly cycles have been reported for few other intertidal invertebrates. We do...
متن کاملBehaviour and Mood Cycles Apparently Related to Parathyroid Deficiency.
INCREASING interest in the cyclic behaviour of man and animals has been evidenced in recent years, especially in so far as these cyclic changes are related to glandular disturbances. In studies of the spontaneous activity of rats the following cycles have been observed: a 4-5-day cycle associated with ovulation (Wang, 1923) ; a 14-day cycle after section of the pituitary stalk (Richter, 1933) ;...
متن کاملIndependent cycles and chorded cycles in graphs
In this paper, we investigate sufficient conditions on the neighborhood of independent vertices which imply that a graph contains k independent cycles or chorded cycles. This is related to several results of Corrádi and Hajnal, Justesen, Wang, and Faudree and Gould on graphs containing k independent cycles, and Finkel on graphs containing k chorded cycles. In particular, we establish that if in...
