Wallabies living near humans breed later in the season, potentially missing valuable resources that could mean the difference between life and death for their growing offspring.
New research published last month in Proceedings B that found that light pollution in Australia is putting the tammar wallaby (Macropus eugenii) out of sync with the seasons. Robert and colleagues from La Trobe University in Melbourne studied wallaby breeding near urban areas and in natural bush, and found that human light pollution prevents the marsupials from responding to light cues that normally signal the start of the breeding season. Wallabies living near humans had lower levels of melatonin, a hormone linked to the sleep-wake cycle, and gave birth on average 27 days later than wallabies in wild conditions. The authors say that this may lead to a mismatch between the birth of young wallabies and food availability.
The idea that the phases of the moon are linked to the human psyche is one of the oldest and most pervasive examples of folk lore and mythology. It is woven into the fabric of our classic literature, poetry and music. Even today, a surprising number of people believe that our deepest emotions and mental states are influenced by the lunar cycle, and there are plenty of police officers, doctors, nurses and prison guards who would swear blind they’ve seen evidence of it in their everyday lives. But is the lunar effect real? How and why does it work? Humans have spent thousands of years discussing the lunar effect in stories and legends, and the last 40 years documenting it in the academic literature. So what’s the verdict? How does the moon affect us?
In it’s simplest form, the Werewolf exemplifies our most primitive understanding of a link between human behaviour and emotion and the moon. It captures our idea that during the full moon, man becomes wild, violent and instinctive, a reversion to a more basal, less civilised version of ourselves. This is probably the most pervasive aspect of the myth, that the moon controls human aggression, impulsivity, violence and mood. But the lunar effect has also been proposed for a range of scenarios so broad it will make your mind boggle. A quick google search will tell you that the moon controls our fertility and reproduction, influences violent crime, suicide and even traffic accidents, affects seizures, blood loss, sleep quality and even our political leanings. All of this begs the question, how and why might such a mechanism exist?
