Thesis title: The Dark Side of Light: The Impact of Artficial Light on Urban Nocturnal Fauna and their Trophic Interactions

Supervisors: Bradley LAW, Dieter HOCHULI , Caragh THRELFALL

Thesis abstract:

Artificial light at night is a very evident, and yet until recently under studied, anthropogenic stressor. A predicted 70% of the world’s human population will be living in urban settlements by 2030 (United Nations 2007), meaning that as human settlements expand, artificial light is set to spread and intensify.
It has been identified as a key threat to global biodiversity. Bats make up a majority of native urban mammal fauna, and most are important insectivorous predators. The species diversity of insectivorous bats, their specific habitat requirements and their nocturnality make them some of the most likely species to be affected by light pollution, and also good models for assessing the impacts of artificial light in cities. My research aims to understand how our use of artificial light in cities shapes the habitat of an urban bat, by investigating the following questions;

  1. What is the impact of new lighting technologies on bats and their insect prey?
  2. Do different functional groups of bats respond differently to artificial light?
  3. What are the impacts of artificial light on critical habitat?
  4. Do bats that have evolved to utilize dark spaces have inappropriate behavioral responses to artificial light?
  5. How possible is the conservation of dark spaces in urban areas?
