The findings of the study, which was based on the records of nearly 500 lion attacks on Tanzanian villagers between 1988 and 2009, said that victims were eaten in over two thirds of cases.
The findings also claimed that most of the attacks occurred between dusk and 10pm on nights when the moon was waning and providing relatively little light, the researchers said.
The Chief investigator of the study, Dr Craig Packer said, "People start out at moderate danger during days 0-4, when the moon is only a sliver and sets shortly after sunset. Danger then declines as the moon gets brighter each evening, with very few attacks in the nights just before the full moon. Then, wham, danger spikes as those hungry lions can now operate in darkness for the rest of the lunar cycle."
"The post-full-moon spike is restricted to relatively few hours of full darkness before the largish moon rises later in the evening," added the researcher.
