Mr Alexander Harcourt


My research focuses on the negative impacts of artificial light at night (ALAN) on nocturnal behaviours. Specifically, I am currently investigating the effect of white LED lighting on emergence behaviour of the Cuban (Osteopilus septentrionalis) and American green (Hyla cinerea) treefrogs. In addition to investigating the effect of ALAN on frog behaviours, I aim to manipulate the LED lighting to the effect of reducing the observed negative impacts.
