Title Light pollution causes object collisions during local nocturnal manoeuvring flight by adult Manx Shearwaters Puffinus puffinus Type Journal Article
Year 2019 Publication Seabird Abbreviated Journal
Volume 31 Issue Pages 48-55
Keywords (up) Animals
Abstract Understanding the detrimental effects of anthropogenic light on nocturnally mobile animals is a long-standing problem in conservation biology. Seabirds such as shearwaters and petrels can be especially affected, perhaps because of their propensity to fly close to the surface, making them vulnerable to encountering anthropogenic light sources. We investigated the influence of light pollution on adult Manx Shearwaters Puffinus puffinus at close range in foggy conditions. We recorded collisions with a building at a breeding colony for six consecutive pairs of intervals in which the house lights were left on as normal for 135 seconds, then turned off for 135 seconds. The relationship between lighting condition and collision frequency was highly significant, with a collision rate in the presence of lighting around 25 times that in its absence. Our results show that birds were clearly affected by the lights, by being either directly attracted, or disorientated during flight close to the structure. This could have been due to the light source itself, or an indirect effect of the all-round reflective glow in the fog perhaps interfering with visual or magnetic control inputs on both sides of the bird simultaneously. Our results suggest a mechanism by which the screening of artificial lights close to shearwater breeding areas, at least during foggy nights, could lead to improved welfare and survival at breeding colonies.

Title Modification of Mammalian Sexual Cycles; Reactions of Ferrets (Putorius vulgaris) of Both Sexes to Electric Light Added After Dark in November and December Type Journal Article
Year 1932 Publication Proceedings of the Royal Society B: Biological Sciences Abbreviated Journal Proceedings of the Royal Society B: Biological Sciences
Volume 110 Issue 767 Pages 322-336
Keywords (up) Animals
Abstract Studies by Rowan (1930 and preceding papers) and Bissonnette (1931, a, b, 1932, a, b, and preceding papers) and Bissonnette and Wadlund (1931) have shown that in juncos, canaries, crows and starlings, at least, among birds, the sexual cycle is conditioned to a great degree by daily light ration. Sexual activity in both males and females can be modified at will by altering the daily light ration with controlled electric lighting from ordinary incandescent bulbs. Gonad changes, controllable in this way, are closely correlated with migrations in juncos and crows, as demonstrated by Rowan (1930, and preceding papers), who, however, maintains that it is the added periods of muscular exercise, rather than the light, as such, that condition these changes, in spite of the fact that it is always the added light he uses, rather than exercise, to get his effects. Bissonnette disagrees, and holds it is the light that is the major factor in conditioning the changes in sexual cycles. It has been found, also, that intensity and colour, or wave-length, as well as daily period of light are factors in conditioning sexual activity in starlings, and the method of increase of light also plays a part (Bissonnette, 1931, b, 1932 ; Bissonnette and Wadlund, 1931).
