LOCOMOTOR ACTIVITY OF FROG 307 1200 0600 cr Z> o I 0000 1800 1200. 0 12 16 18 14 O LUNAR DAY 20 22 (L 24 26 28 OCTOBER-MARCH FIGURE 3.

Activity is randomly distributed throughout the 24 hr period each day with no significant diurnal-nocturnal pattern evident. Diagonal lines indicate times of high and low lunar transit. revealed a change in pattern during July. Thus, three major periods were identi- fied, the first nonrandom period from April through June (79 days), a second non- random period from July to the first New Moon in Octoher (90 days), and the third "random" period from New Moon in October through March of the following year (109 days). The composite "lunar month" isogram constructed for the April to June period (three lunar months) revealed a coherent sinusoidal pattern with periods of in- creased LA (> 10%/two hours) near 0000 hr at New Moon (Fig. 1). This pat- tern shifted toward early evening hours during the progression of the lunar month to exhibit maximal LA at 1800 hr at Full Moon (NM + 15). In addition, a second period of increased activity was observed at 0600 hr which indicated a bi- modal diurnal pattern. During the remainder of the month, the primary activity pattern returned toward 0000 hr and continued the shift to 0300 hr at the end of the lunar month. Thus, a single mode of activity appeared from NM + 16 to NM + 5 of the following lunar month and a bimodal activity pattern from NM + 6 to NM + 15. The isogram based upon a composite of three lunar months of the second period (July through October) revealed a prominent bimodal diel pattern which was maximal at 0400-0600 hr with a minor maximum at about 2200 hr (Fig. 2). The major early morning maximum coincides with the time of sunrise (0430-0600 hr). Please note that these images
