For the first time, sleep was studied in a representative of the order of Sirenia. Slow wave sleep occupied 27%, and paradoxical sleep 1% of the total recording time in the Amazonian manatee. Trichechus inunguis. The circadian rhythmicity of sleep was pronounced. During the sleep period, the manatee woke up for a short time for each respiratory act.(More)
Survivorship of larvae of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), was measured after they were raised on one of six diets. The effects of container shape (wide and shallow vs. narrow and deep), soil depth (0, 0.5, 1.0, 2.0, 4.0, and 8.0 cm), and temperature (28°, 32°, or 35° C) on pupation success was measured.

A Sau3A fragment containing most of the repA gene of plasmid R1 has been cloned in the BamH1 site of the expression vector pAS1. One of the recombinants, pSO1, codes for a fused RepA' protein which is efficiently synthesized both in vivo and in vitro from transcriptional and translational signals of the vector. It is shown that following pSO1 promoted(More)
