Project Summary
Title: The ecological impacts of artificial night lighting on biodiversity. Artificial night lighting is globally on the increase, currently consuming around 1/5th of all electricity use. Despite artificial night lighting's wide spread and high use, the ecological impacts have been largely under explored. Many species are nocturnal or exhibit nocturnal tenancies so altering the night time environment though artificial lighting is likely to have negative impacts.
I'm currently studying the effects of light pollution on bats. Most bat species are nocturnal so sensitive to artificial night lighting and protected across the UK and EU. The areas I will be exploring include impacts on abundance, activity, survival, and also comparisons between 'light-shy' and 'light-attracted' species of bats.
