  Title The daily activity patterns of mayfly nymphs (Ephemeroptera) Type Journal Article
  Year (up) 1968 Publication Journal of Zoology Abbreviated Journal  
  Volume 155 Issue 2 Pages 201-221  
  Keywords Animals  
  Abstract Nymphs of Baëtis rhodani (Pictet), Ephemerella ignita (Poda), Ecdyonurus venosus (Fabricius), Rhithrogena semicolorata (Curtis), and Heptagenia lateralis (Curtis) showed a similar endogenous rhythm of activity under conditions of natural illumination, continuous light and continuous darkness; and were most active at night when they moved from the lower to the upper surface of the stone. The nymphs were positively thigmotactic and negatively phototactic in flowing water, but these taxes and the endogenous activity rhythm of all species except Heptagenia lateralis changed markedly when the flow of water ceased.

  Title Ovulation Rate In Gilts After Short-Time Exposure To Continuous Light Type Journal Article
  Year (up) 1968 Publication Reproduction Abbreviated Journal Reproduction  
  Volume 15 Issue 1 Pages 123-125  
  Keywords Animals  
  Abstract Ovulation rate in gilts maintained under continuous light (daylight plus 118 to 130 lux of artificial light at night) for a complete oestrous cycle during the spring months was not significantly different from that in gilts maintained under normal daylight. Average ovulation rates were 13·4 for controls and 13·1 for treated gilts. A significant (P<0·01) difference in ovulation rate was found between years.

  Title Copepod Phototaxis And Vertical Migration Influenced By Xanthene Dyes Type Journal Article
  Year (up) 1968 Publication The Biological Bulletin Abbreviated Journal The Biological Bulletin  
  Volume 134 Issue 3 Pages 398-410  
  Keywords Animals  
  Abstract 1. Phototaxis of the copepods Paracalanus crassirostris, Calanopia americana, and Acartia lillijeborgi has been measured by determining the percentage of a population moving toward or away from a point source of light per unit time. Quantitative differences in positive phototaxis were found between the species. Photopositive responses differed during the day and night in Acartia but not in Paracalanus and Calanopia.

2. Rhodamine B (8.4 x 10-6 M) brought about the following effects: (a) Locomotor activity was reversibly inhibited in all species. (b) Photopositive responses were increased in Calanopia and Acartia but decreased in Paracalanus. (c) The difference between day and night responses to a point source of light was abolished in Acartia and induced in Calanopia. (d) Somersaulting was induced in Paracalanus but not in the other species.

3. Pyronine B (8.4 x 10-6 M) also decreased locomotor activity. Fluorescein sodium (1.1 x 10-5 M and 1.1 x 10-4 M) was without significant effect.

4. Paracalanus, Calanopia, and Acartia exhibited characteristically distinct diurnal migratory cycles in vertical cylinders, which correlated well with behavior in natural waters. Calanopia and Acartia migrated to the bottom in the daylight whereas Paracalanus and young forms of Acartia were widely distributed vertically during daylight. Specimens of Calanopia and Acartia kept in the dark did not migrate.

5. The effects of rhodamine B (8.4 x 10-6 M) on vertical migration depended upon species, developmental stage, and time of day. In general, rhodamine increased the concentration of animals at the surface at night and at the bottom in daylight. Fluorescein sodium (1.1 x 10-5 M and 1.1 x 10-4 M) had little effect on vertical migration.

6. The effectiveness of rhodamine B and pyronine B is probably related to the presence of diethylamine groups lacking in fluorescein.

  Title The Pineal and Endocrine Function Type Journal Article
  Year (up) 1969 Publication Hospital Practice Abbreviated Journal Hospital Practice  
  Volume 4 Issue 1 Pages 32-37  
  Keywords Human Health  
  Abstract Recognition that levels of hormonal secretion vary markedly from day to night has triggered intensive investigation into the influence of environmental light upon endocrine function. These studies have pointed to the pineal gland as a major mediator of a wide variety of hormonal responses involving the gonads, thyroid, and pituitary, and the hypothalamus and other regions of the brain.
