New paper: #lightpollution suppresses diel migration in #Daphnia, but no detectable difference between urban and rural populations. rdcu.be/eNVwb
So no adaptation to light pollution? We discuss different plausible explanations for this lack of differentiation.

My book #TransformingNight argues that excessive focus on #LightPollution #ArtificialLight during clear-sky conditions until recently is a legacy of astronomy's early attn to issue.
IOW, even recent scientific assumptions and practices have been shaped by the past.

Insightful paper about distance to cities and cloud composition for the distribution and reflection of light pollution. These kind of measurements should become standard for monitoring, eg, of urban lighting impacts particularly on biodiversity beyond the urban environment.

I'm used to the usual effect of clouds (reflection of light pollution, darkening of the natural sky), but it's interesting to see the zenith being darker than "normal" once the sky overhead cleared but Montreal was still covered, and that the zenith became brighter once the sky cleared over Montreal
