Scientists have recognised for some years that
light pollution from buildings, vehicles and streetlights is a growing phenomenon that impacts on the behaviour and success of many animals including migrating birds, hunting bats and the moths they try to capture.
As the human population grows the problem is due to worsen and even remote coastal areas are now being affected by civilization's tell-tale glow-in-the-sky
. Turtles, disoriented as they return to their nesting beaches, or confused hatchlings struggling to find the sea, are iconic examples.Now, a new study conducted by scientists from the University of Exeter and the Plymouth Marine Laboratory and the University of Exeter looks at the
true extent to which light pollution is affecting key marine wildlife in the UK.© Galleries - Looe Marine Conservation GroupDogwelk
The research team set up a series of laboratory experiments to determine whether the less well known, but highly important inhabitants of the seashore were also affected.
Using the dogwhelk (Nucella lapillus), a key seashore species that modulates biodiversity and community structure of our coasts, they kept one group of dogwhelks in artificially-lit night sky conditions, while a control group experienced a more natural night/day cycle.
