So wildlife corridors can be compromised by even a single light and so prevent animals from moving across the landscapes. Predators have an advantage by seeing over a greater area, and their prey must seek darkness and spend more time hiding. The prey has less time to use for normal activities. What is the biological affect? Melatonin production, which is dark dependent, is suppressed when the dark is interrupted at night.
Artificial light is linked to diabetes, depression, failure at school, and difficulties in concentrating. Some studies indicate a link between artificial light and obesity as well.
On our campus, the NIH Office of Research Facilities has undertaken a long term re-lamping program to change out over roadway and walkway lamps to lower energy LEDs and to redirect the light beams only where needed. The program, when completed, will insure that the Federal Security mandates for illuminating our campus are met.
It will also help to:. The walkway lights that were installed comply with the IDA dark sky requirements mentioned above. One benefit to the new LED fixtures is that each of the LEDs that make up the fixture contains a different shaped lens that directs the light from that LED to a specific spot.
The LED roadway fixtures have zero up lighting unlike previous lighting technologies that relied on reflectance within the fixture itself to direct light to the ground.

These are all nocturnal hunters and have a wide variety in their diet. A nesting pair of owls is capable of capturing and eating thousands of small rodents per year, and are favorites on farms and homesteads for their exterminating abilities.
Owls are nocturnal, so they have fantastic eyesight and hearing to assist with hunting. Their ears are placed slightly off-center of one another so that the owl can most accurately pinpoint the location of their prey, even in pitch black.
Their specialized feathers are also adapted to the night, as they silence their approach and allow them to be incredibly stealthy when hunting. The biggest difference is in the fur color and the location, with the Red Fox preferring the northern climate while the Gray Fox prefers the south.
Foxes are relatively shy, so they prefer to forage nocturnally and use their superior eyesight and hearing to catch mice, rats, and rabbits. They are omnivores and will happily supplement their diet with fruits, berries, and even insects! A capybara is a large rodent that resembles an overgrown guinea pig and can grow about 4 feet long, which is around the size of a medium dog. They have no natural predators in the U.
