Editing Nocturnality (section)

==== Reproduction ====
There have been documented effects of light pollution on reproductive cycles and factors in different species. It can affect [[mate choice]], migration to breeding grounds, and nest site selection.<ref name=":1" /> In male [[Northern green frog|green frogs]], artificial light causes a decrease in mate calls and continued to move around instead of waiting for a potential mate to arrive.<ref name=":5">{{Cite journal|last1=Baker|first1=B.J.|last2=Richardson|first2=J.M.L.|date=October 2006|title=The effect of artificial light on male breeding-season behaviour in green frogs, Rana clamitans melanota|journal=Canadian Journal of Zoology|volume=84|issue=10|pages=1528–1532|doi=10.1139/z06-142|bibcode=2006CaJZ...84.1528B |issn=0008-4301}}</ref> This hurts the overall [[Fitness (biology)|fitness]] of the species, which is concerning considering the overall decrease in [[amphibian]] populations.<ref name=":5" />

'''Predation'''

Some nocturnal predator-prey relationships are interrupted by artificial lighting. Bats that are fast-moving are often at an advantage with insects being drawn to light; they are fast enough to escape any predators also attracted to the light, leaving slow-moving bats at a disadvantage.<ref name=":1" /> Another example is [[harbor seal]]s eating juvenile [[salmon]] that moved down a river lit by nearby artificial lighting. Once the lights were turned off, predation levels decreased.<ref name=":1" /> Many diurnal prey species forced into being nocturnal are susceptible to nocturnal predators and those species with poor nocturnal eyesight often bear the brunt of the cost.<ref name=":3" />
