TLDR
Although anthropogenic light sources appear to advance the onset of LH secretion in urban tree sparrow populations, they also lower peak LH, and consequently levels of T and E2, according to a linear mixed model (LMM).About:

Impacts of Artificial Light at Night on Biological Timings
TL;DR: Support is added to arguments that artificial nighttime lighting has a quite pervasive and marked impact on ecological systems, that the rapid expansion in the global extent of both direct illuminance and skyglow is thus of significant concern, and that a widespread implementation of mitigation measures is required.
Journal ArticleDOI
A meta-analysis of biological impacts of artificial light at night
TL;DR: The breadth and often strength of biological impacts revealed highlight the need for outdoor artificial night-time lighting to be limited to the places and forms—such as timing, intensity and spectrum—where it is genuinely required by the people using it to minimize ecological impacts.

Light pollution alters the phenology of dawn and dusk singing in common European songbirds
TL;DR: The hypothesis that artificial night lighting alters natural seasonal rhythms is supported, independently of other effects of urbanization, by finding that in four species dawn and dusk singing developed earlier in the year at sites exposed to light pollution.
Journal ArticleDOI
Early life exposure to artificial light at night affects the physiological condition: An experimental study on the ecophysiology of free-living nestling songbirds.
TL;DR: Experimental field evidence is provided that ALAN affects nestlings' physiology during development and early life exposure to ALAN could therefore have long lasting effects throughout adulthood.
Journal ArticleDOI
Working with Inadequate Tools: Legislative Shortcomings in Protection against Ecological Effects of Artificial Light at Night
TL;DR: In this paper, the authors present the results of an analysis of the current legal obligations on artificial light at night in context with a systematic review of adverse effects, and discuss the conditions for prohibitions by environmental laws and whether protection gaps persist and, hence, whether specific legislation for light pollution is necessary.

Ecological light pollution
Travis Longcore,Catherine Rich +1 more
TL;DR: The more subtle influences of artificial night lighting on the behavior and community ecology of species are less well recognized, and constitute a new focus for research in ecology and a pressing conservation challenge.

Reproduction and resistance to stress: When and how
TL;DR: Four mechanisms underlying resistance of the gonadal axis to stress are suggested, likely genetically determined, and their expression may depend upon a complex interaction with environmental factors.

TL;DR: It is argued that, in addition to altered habitat structure, three major processes contribute to the patterns of reduced species diversity and elevated abundance of many species in urban environments.

Photoperiodic Control of Seasonality in Birds
TL;DR: This review examines how birds use the annual cycle in photoperiod to ensure that seasonal events—breeding, molt, and song production—happen at the appropriate time of year.
