Australian zoologist Kylie Robert and colleagues have published an exciting new paper on the disruption of breeding patterns and melatonin levels in a free-ranging native mammal. I had the chance to comment on the significance of this research for Science News and am delighted that Dr. Robert will also be presenting at the Annual General Meeting of the International Dark-Sky Association on November 15 in Phoenix. To my knowledge, this paper is one of the first showing these kinds of effects, such as lowered blood melatonin levels, in the field and joins recent work by Davide Dominoni, who showed impacts from night lighting on the physiology of wild birds.
