Study of insects shows that street lighting affects ecosystem
City lights have an unexpectedly strong effect on insect populations, favoring some species and harming others, according to a study that raises new questions about the human impact on wildlife.
Scientists led by Thomas Davies of the University of Exeter, southwest England, spent three days in August 2011 by installing insect traps in the vicinity of Helston, a small town in Cornwall.
Five species, including ants, ground beetles and bugs-believe, were much more abundant invue in lighted areas compared to areas located between points of light. City Lights also attracted more predatory insects and ghouls.
"Urban lighting changes the environment at higher levels of biological organization than we knew before, revealing the potential of being able to change the structure and function of ecosystems," says the study.
