The purpose of the study was to determine an emergence
rhythm, its period, and the developmental stages susceptible to
emergence synchronization in the leafcutter bee Megachile rotundata
(Fabricius). An attempt was made to determine if an oxygen consumption
rhythm was present in the pupal and adult stages of the
alkali...
The rhythms of emergence, oxygen consumption, and activity
were studied in Megachile rotundata with the object of comparing the
results to the major properties of the biological clock such as temperature
independence, susceptibility to light synchronization, and
entrainment. A further objective was to compare the three rhythms
to determine if...
Over 56,000 hours of locomotor activity of Taricha granulosa
were recorded using two types of low cylindrical plastic monitoring
chambers. This species shows distinct rhythms of activity under
normal day-night cycles, shortened day-night cycles, constant
darkness (DD) and constant light (LL). The rough-skinned newt is
day active and crepuscular. I...
The theory of Biorhythms is an up and coming topic.
Its founding fathers: Dr, Fliess, Dr. Swoboda, and
Dr. Teltsher discovered the 23 day physical 28 day sensitivity,
and 33 day Intellectual cycles around the turn of the century.
Today, biorhythms are being looked at and studied
from many different...
Purpose: The general problem was to determine the relationship between biorhythms and injuries to college football participants representing Oregon State University. Procedures: The population consisted of one hundred and ninty two football players representing Oregon State University who participated in the intercollegiate football seasons of 1981 and 1982. Injury data...
Biorhythm theory proponents believe that humans have
a 23-day physical cycle, a 28-day emotional cycle, and a
33-day intellectual cycle. According to biorhythm theories
a person in the positive portion of any single cycle, the performance potential is enhanced for those tasks related to
that particular rhythm. When each cycle...
Daily (circadian) rhythms exist at molecular, physiological, and behavioral levels and coordinate many life functions. This coordination is believed to contribute to an organism's fitness, however, such contributions have not been convincingly demonstrated in any animal. The most significant measure of fitness is the reproductive output of the individual and...
The genetic basis of adaptation is complex as many fitness-related traits are quantitative and likely influenced by multiple genes with variable effects across different selective environments. One important adaptation for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which individuals return to natal breeding sites within a reproductive season....
