Most studies in chronobiology focus on solar cycles (daily and annual). Moonlight and the lunar cycle received considerably less attention by chronobiologists. An exception are rhythms in intertidal species. Terrestrial ecologists long ago acknowledged the effects of moonlight on predation success, and consequently on predation risk, foraging behaviour and habitat use, while marine biologists h...

 I argue it is inconsistent to believe that overconsumption is wrong or bad yet believe that having children is morally permissible, insofar as they produce comparable environmental impacts, are voluntary choices, and arise from similar desires. This presents a dilemma for “mainstream environmentalists”: they do not want to abandon either of those fundamental beliefs, yet must give up o...

The authors reject Joseph Fletcher's arguments that the choice to procreate is a privilege and that parents may be responsible in certain circumstances for producing genetically defective children. They argue instead that procreation is a conditional right, but nonetheless conclude that parents may be held responsible for the "wrongful life" of genetically damaged offspring based on the legal ...

Cupchik. G. C. & 8erlyne, D. E.: The perception of collatÎve properties in visual stimuli. Scand. J. Psychol. 20, 93-104, 1979. Two experiments were conducted to determine how quickly subjects respond to collative properties (e,g., Complexity, Uncenainty) of visual stimuli. In Experiment I subjects were presented with reproductions of paintîngs and artificial patterns which varied in collative ...

an important part of male infertility of unknown etiology may be attributed to various environmental and occupational exposures to toxic substances, such as lead. the reproductive effects of lead are complex and appear to involve multiple pathways, not all of which are fully understood. it is still unclear, for example, if male reproductive issues in lead-exposed persons are mostly related to t...
